Facts
There are certain experiences which are undoubtedly true. The book we have in front is one of these. Certain deductions are apodictic. These experiences have been tempting philosopher since the very beginnings. The analytical philosophers have been this century particularly obsessed with such truths. To their minds they are like clews which they hope to follow to absolutely certainty. Such is the origin of the philosophical use of facts. Facts constitute states of affairs. In sum, both refer to the evidence of the senses and to logic. But to designate the set of such truths with the terms reality and being will not do, because both reality and being embrace also untruths, illusions, errors, and so on.
Factuality, factual propositions
Factuality refers to necessary truths.
Perceptions are factual propositions.
Fatalism

Determinism
Fine grain, coarse grain
These paired metaphors are taken from photography. Coarse grain refers to the larger picture involving metaphysical principles. Fine-grain is akin to the bottom up strategy.
Fixation
Fixation is the self fixing upon itself as it fixes upon external objects.
As such, it easily turns into anxiety because it cannot manipulate mental events in the way that the hand manipulates objects.
Fixation is the quintessence of introspection in so far as it makes mental events as real as things, in the sense that things are resistant to our touch.
Fodor
(1) Fodor seems to
believe that knowledge is belief when he makes it his chore to defend a strong
distinction between perception and inference
Now, for one thing,
belief is not a condition for knowledge
I can suspect that
something is true which is indeed true, and yet I may not believe in what I
suspect and the proposition which expresses my suspicion would still be valid
But my touble with his
concerns goes deeper than that
It has to do with two
different basic approaches to knowledge
As he sees it for
something to be knowledge it must become a belief
Otherwise, why would he
bother to distinguish between perception and inference, which are cognitive
propositions, in terms of belief formation?
But belief in my theory
is part of a propositional base underlying all propositional content
Propositional content is
the product of cognitive processes
These cognitive processes
can produce belief, denial or belief, a neutral, noncommittal stance, and
"shades" in between these attitudes
The bases of
propositiional content are always valid
Propositional content
itself may or may not be valid
So, applying my theory to
Fodor's mistaken approach we get the following propositions
Cognitive processes
produce propositions
Propositions have
propositional bases
One of these bases is the
belief-proposition
Cognitive processes can
determine the form of the propositional base involving belief, but they do not
necessarily do so, i.e., we can have cognitive processes which produce
propositions involving neither belief nor unbelief
There are cognitive
processes other than perception and inference
Some propositions are
self-justificatory: neither perceptual nor inferential
Some controversial
propositions, which could possibly be valid, are not inferential, i.e.,
originate in some associative subconscious process of squiggles
Finally, to say inference
without more ado leaves too much up in the air, for there are various sorts of
inference, among them, just to be summary and quick about it, probabilistic
inference, inductive or empirico-rational inference, and logico-mathematical
inference
We must mention, in
addition, that there are two types of scientific inference: a type related to
inductive inference, which leads to scientific hypotheses, and lawful scientific
inference, which is very much like logic-math inference
(2) I am reading a book
whose contents I detest
This is a personal
attitude
It implies the self, and
the self is a special set of squiggles
In Fodor's view meaning
is a rational process
All that mind does is to
translate the contents of the book into mentalese
But the presence of
affects as adjunts to meaning imply that meaning and Fodor's version of
mentalese cannot account for my mind's reading of the book
More than mental meaning
goes into my reading of the book
(3) I am reading a book
whose contents I detest
In Fodor's view meaning
is a rational process
All that mind does is to
translate the contents of the book into mentalese
But the presence of
affects as adjunts to meaning imply that meaning alone and Fodor's version of
mentalese cannot account for my mind's reading of the book
More than mental meaning
goes into my reading of the book
Fodor, The Language of
Thought (1975)
Wittgenstein confused
dualism with mentalism
It is possible to have
mentalism without dualism
"But representation
presupposes a medium of representation, and there is no symbolization without
symbols. In particular, there is no internal representation without an internal
language"
Infra-human organisms and
the pre-verbal infant think in the sense of considered action, concept-learning,
and perceptual integration
They do not know a
natural language
Therefore, a natural
language cannot be the medium of thought
Only computer models as
representational systems can give account of non-verbal thought
"We have no notion at all
of how a first language might be learned that does not come down to some version
of learning by hypothesis formation and confirmation"
"Similarly, learning the
truth conditions on P would be a matter (not of hypothesizing and conforming
that the corresponding truth rule applies, but just) of having one's response
dispositions appropriately shaped.
"A number of
philosophers who ought to know better, apparently, accept such views.
Nevertheless, I shall not bother running through the standard objections since
it seems to me that if anything is clear it is that understanding a word
(predicate, sentence, language) isn't a matter of how one behaves or how one is
disposed to behave. Behaviour and behavioural dispositions, are determined by
the interactions of a variety of psychological variables (what one believes,
what one wants, what one remembers, what one is attending to, etc.). Hence, in
general, any behaviour whatever is compatible with understanding, or failing to
understand, any predicate whatever"
Actually, there is
teaching before hypothesis formation
A parent teaches words to
a child
That the child later
might ask is this the word that designates this object cannot be considered a
form of hypothesis testing
The child is appealing to
an authority
A child will fight tooth
and nail for a definition it got from his parents against a stranger's version
of the same word
This is not an inductive
process
In this book Fodor works
hand in glove with Chomsky
Chomsky holds that
language universals are innate
A child supposedly tests
grammars against language universals
But do not language
universals as such entail a grammar?
In any event, the
Fodor/Chomsky argument is that both language universals and grammars imply a
mental language, which is not a natural language because it is precisely a
natural language that the child is learning
Learning the semantic
properties of a predicate [noun, verb, adjective, et al] is learning the
extension of the predicate
This involves a truth
rule for that predicate
"S learns P only if S
learns a truth rule for P"
The truth rule consists
in knowing what it is in the world that the predicate is true of
If we already know a
language which is at least as extensive as the natural language that we learn,
then obviously the language we already know must of necessity contain the real
extension of all the predicates that we can learn when we learn the natural
language
"But one cannot learn
that P falls under R unless one has a language in which P and R can be
represented. So one cannot learn a language unless one has a language in which P
and R are prepresented. In particular, one cannot learn a first language unless
one already has a system capable of representing the predicates in that language
and their extensions. And...that system cannot be the language being learned.
But first languages are learned. Hence, at least some cognitive operations are
carried out in languages other than natural languages"
But I can know a
predicate without knowing its full extension
And is it ever possible
to know the full extension of a predicate?
Take table and table
mountain
The figurative
possibilities of predicates are quite unpredictable
Pegasus is a winged horse
cannot be understood because there are no conditions under which this
proposition would be true
Or take a dragonfly is a
winged insect
How do I know that insect
extends to wings?
Insect could refer
exclusively to the metameres or some other insect feature not including wings
It is possible to argue
that every P has a definition and that it is from the definition of P that we
determine its extension
Only experience can give
you the true extent of a proposition
"I will argue primarily
that you cannot learn a language whose terms express semantic properties not
expressed by the terms of some language you are already able to use. In
formulating this argument, it is convenient to assume that the semantic
properties expressed by a predicate are those which determine its extension,
since, whatever its faults may be, that assumption at least yields a sharp sense
of identity of semantic properties (two predicates have the same semantic
properties if they apply to the same set of things)"
This of course leaves out
grey areas, figurativeness, connotations, intensions, and so on
It is possible to speak
of beauty in relation to art or to the world, and the meanings are different
Beauty in nature is
sensuality
Beauty in art is more
formal than sensual
No predicate can be
exactly as extensive as another, although this is not to say that synonymy is
not possible
"...what happens when a
person understands a sentence must be a translation process basically analogous
to what hapens when a machine `understands'...a sentence in its programing
language"
"One way of describing my
views is that organisms (or, in any event, organisms that behave) have not only
such natural language as they may happen to have, but also a private language in
which they carry out the computations that underlie their behaviour"
Fodor here deliberately
sets up a phony confrontation with Wittgenstein, who denied the possibility of a
private language
In Wittgenstein the
primary definition of a private language is that it is one that only expresses
what an individual experiences, e.g., the use of arbitrary sounds that
correspond to no existing language in order to designate experiences that every
one has or can have
And in this sense the
mental language, if it is to make any sort of sense at all, cannot be a private
language
The private language that
makes learning possible has to be the same for all individuals, especially as it
has to be innate
Learning is an universal
process
It is not admissible that
human beings should know they know if the innate system for learning they have
were peculiar to each individual
However, there is another
Wittgensteinian definition of a private language and that is that it is a
"language for the applicability of whose terms there exist no public criteria
(or rules or conventions)"
What Fodor claims he
wants to prove is that this definition of a private language does not apply to
his thesis of a mental language
Or to put it another way:
that it is possible to use a private language coherently if not exactly
according to public criteria
"Notice...that the use of
a language for computation does not require that one should be able to determine
that its terms are consistently employed; it requires only that they should in
fact be consistently employed...The soundness of inference is not impugned by
the possibility of equivocating, but only by instances of actual equivocation"
Isn't this an implicit
denunciation of Gedanken?
"We must give some sense
to the notion of terms in an internal representational system being used
coherently and we must show how that sense is at least reasonably analogous to
the sense in which the terms in public languages are coherently employed"
His argument
fundamentally is that if it is conventions that make for coherence in public
languages it is the facts of the world that create those conventions and the
same facts can be used to demonstrate the coherence of a private language
Coherence requires a
stable relation between the way terms are used and the way the speaker believes
the world to be
In a natural language
conventions determine such coherence
Such conventions are the
rules which pair propositional attitudes like beliefs with the forms of words
that express these attitudes
In a Wittgenstein private
language the relation between language forms and propositional attitudes is not
mediated by public conventions
The challenge that the
private language argument poses to the notion of a language of thought is: show
how such a relation could be mediated other than public conventions
To my way of seeing
things, the question really is: how does a system of representation apply logic,
make perception possible, and so on?
But no matter
Fodor's argument seems to
be that an organism shows coherence if there is correspondence between its
beliefs and the ways things are in the world and that for the same coherence to
obtain in relation to a private language it is necessary to assign the formulae
of the private language to the coherent states of the organism
"Any psychological
theory...will have to ascribe a special role to the computational states for
organisms, viz., the way that information is stored, computed, accepted,
rejected, or otherwise processed by the organism explains its cognitive states
and, particularly, its propositional attitudes"
"Finally, and this is the
important [condition for the ascription of computational processes to
organisms], that for any propositional attitude of the organism (e.g., fearing,
believing, wanting, intending, learning, perceiving, etc., that P) there will be
a corresponding computational relation between the organism and some formula(e)
of the internal code such that (the organism has the propositional attitude iff
the organism is in that relation) is nomologically necessary"
In Wittgenstein inputs
plus conventions produce belief
Belief is conventional
In Fodor inputs plus code
language produce belief
Belief is nomologically
necessary
In sum, prop-att
psychology presupposes a self and awareness and representation
"There are...two
things--the organism's relation to propositions and the organism's relations to
formulae--and these two things are so arranged that the latter is causally
responsible for the former (e.g., the organism's being in a certain relation to
the formulae causes the organism to be in a certain relation to propositions). I
can imagine that someone might want to resist this picture on metaphysical
grounds; viz., on the grounds it takes propositions (or, anyhow, relations to
propositions) as the bedrock on which psychology is founded"
There must be a
computational formula for every propositional attitude is a law
But there is no
difference between perceiving and perceiving that P
The act of perceiving is
itself a proposition
Therefore, for every
proposition there is a symbolic formula
Fearing necessarily must
be fear of something
Fear without cause is not
experienceable (pace Kierkegaard)
"What is required...is
that there should be the right kind of correspondence between the attitudes the
system bears to propositions and the relations that it bears to formulae of the
language...We remarked that, in the case of natural languages, the relevant
correspondence between the speaker's relation to formulae and the attitudes he
bears to propositions is mediated by his adherence to the conventions that
govern the language. In the case of the internal code, it is presumably
determined by the innate structure of the nervous system"
"It remains an open
question whether internal representation, so construed, is sufficiently like
natural language representation so that both can be called representations `in
the same sense'...Since public languages are conventional and the language of
thought is not, there is unlikely to be more than an analogy. If you are
impressed by the analogy, you will want to say that the inner code is a
language. If you are unimpressed by the analogy, you will want to say that the
inner code is in some sense a representationsl system but that it is not a
language. But in neither case will what you say affect what I take to be the
question that is seriously at issue: whether the methodological assumptions of
computational psychology are coherent. Nothing in the discussion so far has
suggested that they are not. In particular, nothing has prejudiced the claim
that learning, including first language learning, essentially involves the use
of an unlearned internal representation"
Computation and unlearned
are oxymoronic
In my view propositional
attitudes are the propositions themselves
When we have a
proposition, be it perception, thought, or affect, we already have a
propositional attitude
There can be no
propositional attitudes without propositions
The so-called formulae of
the code language are the propositions themselves
In Fodor the code
language determines our propositional attitudes
In Wittgenstein it is the
conventions of the natural language that do so
How do I justify that all
mental contents are propositions?
Aristotle called
sensations propositions
The thesis is implicit in
Fodor
We can say yes or no to
all our mental contents
We could if we had the
time describe in words each and every one of the instants of mind
And if not in words it
can be argued that propositions are not necessarily only verbal
The question of meaning
entails a system of representation
A system of
representations entails propositions
What the private
language must be like
"...(E)very compound
predicate is constructed from elementary predicates in some manner that the
truth definition is required to make explicit...(A) truth definition for a
natural language contains a list of representations which determine the
extensions of its elementary predicates and a set of rules defining its complex
predicates in terms of its elementary predicates...The upshot would appear to be
that one can learn L only if one already knows some language rich enough to
express the extension of any predicate of L. To put it tendentiously, one can
learn what the semantic properties of a term are only if one already knows a
language which contains a term having the same semantic properties."
In order to learn a
language one must have the means to represent its elementary predicates and to
build complex predicates from them, and this implies the existence and operation
of another, a previous private mental language
"...(T)here is no
principled reason why the experiences involved in learning a natural language
should not have a specially deep effect in determining how the resources of the
inner language are exploited.
"What, then, is
being denied? Roughly, that one can learn a language whose expressive power is
greater than that of a language that one already knows. Less roughly, that one
can learn a language whose predicates express extensions not expressible by
those of a previously available representational system. Still less roughly,
that one can learn a language whose predicates express extensions not
expressible by predicates of the representational system whose employment
mediates the learning.
"Now, while this is
all compatible with there being computational advantage associated with knowing
a natural language, it is incompatible with this advantage being, as it were,
principled. If what I have been saying is true, then all such computational
advantages--all the facilitatory effects of language upon thought--will have to
be explained away by reference to `performance' parameters like memory, fixation
of attention, etc."
"It should now be clear
why the fact that we can use part of a natural language to learn another
part...is no argument against the view that no one can learn a language more
powerful than some language he already knows. One cannot use the definition D to
understand the word W unless (a) `W means D' is true and (b) one understands D.
But if (a) is satisfied, D and W must be at least coextensive, and so if (b) is
true, someone who learns W by learning that it means D must already understand
at least one formula coextensive with W, viz., the one that D is couched in."
This is legerdemain in
various senses that can be easily demolished
What I want to get at is
at the kernel of truth and the kernel of distortion
True, we have the system
of representation and this system comports rules and makes possible learning
processes
However, (1) we cannot
limit this system to the concept of language
It is more than a
language
It is a language and all
the instructions and rules that the language can represent and apply
Therefore, (2) this
systems embraces all cognitive processes and not just language learning
Primarily, in fact, it
contains all the rules of intuitive logic, and many of the learning operations
which Fodor attributes to learning a language can be explained by appealing not
to a private language for learning a natural language but to the larger system
of representation in which logic is embedded
Piaget's argument is that
the child has a rudimentary grasp of symbols (x) which makes language
acquisition possible
With language the child
then improves his ability to grasp symbols, and with this he expands his ability
to know and use language
Fodor negates that x can
expand in this way
"It might really turn out
that the kinds of representational system that children use is, in a principled
sense, weaker than the kind of system that adults use, and that a reasonable
account of the stages of cognitive development could be elaborated by referring
to increases in the expressive power of such systems. What I think one cannot
have, however, is that concept learning provides the mechanisms for the
stage-to-stage transition. That is, the child's cognitive development is
fundamentally the development of increasingly powerful
representational/conceptual systems, then cognitive development cannot be the
consequence of concept learning."
The vocabulary of
internal representations
"We commenced this
discussion by assuming--along with most of current linguistics, generativists
and interpretativists--that there is a level of representation at which words
are replaced by their defining phrases...but we ended by advocating a solution
which recognizes `only' at the deepest level to which transformartions apply,
and which acknowledges a richer system of cross-referencing than standard
quantificational logic employs at the level for which inference is defined"
Sounds like a reference
to intuitive logic
"Some properties of
language of thought must, in short, be represented in the language of thought
since the ability to represent representations is, presumably, a preconditon of
the ability to manipulate representations rationally"
Do we manipulate
cog-processes?
Or is all of mind
outsourced from the subconscious?
The temporality of
mind--the instantenity of awareness--inclines me to believe that all thought is
produced by the subconsious
This is certainly true of
the newborn
Why shouldn't it go on
being true of all specific selves throughout life?
But does awareness affect
the subconscious at all?
This could be argued for
if we could claim, e.g., that we choose what to think about
But we can equally argue
that in "choosing" what to think about we are actually responding to a
subconscious cog-process
Or is choosing not a
cog-process?
If we could act in a
manner that is independent of cognition and cog-processes, and only in such a
case, could we argue for the effects of the conscious on the subconscious
But we cannot!!!
If we can argue for the
existence of intuitive logic and of rules of perception as two different sets of
mental postulates, as two different sets of basic-cog's, and if we also argue
for the interactiveness of the different sets of basic-cog's--and if we admit
that memory has its rules, as Fodor does indeed admit, then the previous
arguments must be valid, for there must be different cog-processes and these
cog-processes all presuppose memory--then we have to recognize that, as Fodor
puts it, the language of thought must be represented in the language of thought,
or as I prefer to put it, that there are rules of squiggles different from all
other sets of basic-cog's
Finally, if we assume
rules of perception and if we define awareness as perception and introspection,
then, since there are rules of perception, there must also be rules of
introspection
But since introspection
is really nothing more than our ability to represent mental contents, then the
rules of introspection must be the entire set of all different sets of
basic-cog's
And where does all this
leave us on awareness?
Awareness is perception
and introspection
Consequently awareness is
nothing but the interactive operation of all basic-cog's
Doesn't this refer to
introspection since the rules of introspection are the totality of basic-cog's?
It would seem so
However, since
introspection is the ability to represent, then properly speaking the rules of
introspection must be the rules of representation, i.e., of squiggles, and since
there is some representation that is not introspectivem, then introspection can
be accounted for by some but not all of the rules of squiggles
The problem is which
exactly?
The working proposition
is that among the rules of squuiggles must be some which determine what we shall
have in the mind at any given moment that is not identical with perception
We are getting a bit
twisted up here
Awareness is our ability
to perceive and to introspect and to distinguish between the two and their
respective contents
Is the awareness of
perception or introspection different from specific acts of perceiving and
introspecting?
We can distinguish
between a perception and thought about a perception
Both are awareness
Thought about perception
or introspection is necessarily awareness of the past
In the case of perception
it is the introspection of past perceiving
In the case of
introspection it is awareness of awareness
All of these particulars
are constitute forms of awareness
And when we say that
awareness is perceiving and introspecting and distinguihsing between the two, we
are not excluding the introspection of past perception and of past introspection
Awareness is the result
of the interactivess of all basic-cog's and processes
It is not the only result
but it is sufficiently explained from the source of all mental contents, aware
and non-aware
There are no rules
necessary to explain awareness beyond basic-cog's
And what about
introspection?
The same reasoning
applies
But there are rules of
perception?
Shouldn't there be rules
of awareness and rules of introspection?
Not really!!
The interactiveness of
basic-cog's is present in all of awareness
It is the interactiveness
of basic-cog's and processes that accounts for awareness and consequently for
introspection and perception
Since thre are rules of
perception, then these rules determine awareness and also intervene in
introspection
There is no such a huge
gap between perception and introspection
The only difference is
that perception has specific rules and introspection does not have specific
rules
It could be argued then
that awareness is more like introspection, but we can hardly leave perception
out of any definition of awareness, can we???
Since however we can have
perception without introspection, then of the trio of concepts we are defining
we must admit that the least susceptible to specification is introspection
What then is
introspection???
No more and no less, then
awareness!!!
Conclusion: scope and
limits
"At the heart of the
picture, the fundamental explicandum, is the organism and its propositional
attitudes: what it believes, what it learns, what it wants and fears, what it
perceives to be the case...To have a certain propositional attitude is to be in
a certain relation to an internal representation. That is, for each of the
(typically infinitely many) propositional attitudes that an organism can
entertain, there exist an internal representation and a relation such that being
in that relation to that representation is nomologically necessary and
sufficient for (or nomologically identical to) having the propositional
attitude."
If such is the case, if
one specific propositional attitude corresponds to one specific representation,
then the distinction between propositional attitude and representation escapes
me: they are both identical dated particulars
Why then not speak simply
of propositions, of mental states as being propositions?
"Mental states are
relations between organisms and internal representations, and causally related
mental states succeed one another according to computational principles which
apply formally to the representations."
This is the proposition
that cognition is the only condition for belief, which is plain cussedness
It is probably true that
mental states are caused and relate causally in sequence or succession, but to
say that this occurs according to computational principles is a mere assumption,
and a wrongheaded one: computational principles make no room for affects and
affects are part of all individual causal chains
Fodor says that his
psychology will not work unless "organisms have pertinent descriptions as
instantiations of some or other formal system", and he goes on: "What pertinency
requires is (a) that there be some general and plausible procedure for assigning
formulae of the system to states of the organism; (b) that causal sequences
which determine propositional attitudes turn out to be derivations under the
assignment; (c) that for each propositional attitude of the organism there is
some causal state of the organism such that (c1) the state is interpretable as a
relation to a formula of the formal system, and (c2) being in that state is
nomologically necessary and sufficient for (or contingently identical to) having
the propositional attitude."
He admits that the
requirements of pertinency can not be carried out because of certain "glaring
facts about mentation which set a bound to our ambitions...It is, I think, next
thing to dead certain that some of the propositional attitudes we entertain
aren't the results of computations."
The example he gives is
purely physiological--"brute incursions from the physiological level", like
pain--and this only alludes to the problem on its edges
However, he then broadens
his perspective
"The mental life is, as
Davidson (1970) suggested, gappy. (Footnote: As is the domain of any other of
the special sciences. If the world is a continuous causal sequence, it can be so
represented only under physical description.) Those of one's propositional
attitudes that are fixed by computations form the subject matter for a science
of the kind that we have been examing. But those that aren't don't, and that
fact provides for the possibility of bona fide mental phenomena which a theory
of cognition cannot, literally in principle, explain...On the contrary, some of
the most systematic, and some of the most interesting, kinds of mental events
may be among those about whose etiology cognitive psychologists can have nothing
at all to say.
"The most obvious
case is the causal determination of sensation. Presumably the perceptual
integration of sensory material is accomplished by computational processes of (a
general sort). But the etiology of sensory material must typically lie in causal
interaction between the organism and sources of distal stimulation, and such
interactions have, almost by definition, no representation in the psychological
vocabulary...Cognitive psychology is concerned with the transformations of
representations [propositions], psychophysics with the assignment of
representations to physical displays."
Let us start with a
summary of Fodor
There is the organism
The organism has
computational abilities, propositions, and propositional attitudes
It processes information
or propositions, which then determine the propositional attitudes
The propositional
attitudes are the result of the organism's computational ability
But the organism is also
physical
Even though ultimately
the propositional attitudes must correspond to physical states, Fodor makes a
strong distinction between the two
He assumes isomorphism
The strong distinction is
based on sensations, i.e., physical pain and pleasure, but also just ordinary
sensory inputs
His cognitive psychology
cannot account for sensation
But this proposition is
nonsense, because there is no way that you can speak of an internal division
between computational and non-computational mental states
You have to account for
all mental events, and this includes sensations and physical pain and pleasure
I find his perplexity
perplexing
Why should the relation
between the perceiver and the perceived have any relevance to the process
whereby sensations becomes perceptions and to the characterization of
perceptions as propositions?
Would it not be possible,
for instance, to construct a model of the way in which sensations come together
in mind as recognizable images?
Hasn't this been
attempted in various ways?
Of course psychology
"knows nothing about the stimulus", but what exactly does this mean?
After all, psychology is
about mind and not about the material world
Since perceptions are
propositions, hence formulable in the internal code, then sensations too must
have some representational value, and I should think, prima facie, that
cognitive psychology would be interested in the way that sensations become
perceptions, that is, how some a form of representation is turned into a more
complex form of representation
Does this observation
clash with my own belief that pain is not a form of representation
Is pain, or pleasure, in
the same category as sensory inputs?
The causes of pain and
pleasure act directly upon the nervous system, whereas sensory inputs are, as
Fodor says, distal stimuli
But how about the pain of
the sun directy in the eyes?
It is not the sun but
emanations from the sun
Taste and physical
sensation cause representations
Why should pain and
pleasure be different?
We know that such is the
case
We feel pain and pleasure
but we do not process them
Stimuli of this sort have
physical causes, whose effects can produce propositions
This logic might apply to
all sensations, and it is this possibility of propositional content from
sensation that seems to lie at the root of an explanation of perception
However, it is valid that
sensations seem to be at the seam between mind and body
The sharp separation
between psychology and "psychophysics" that Fodor posits is not tenable
Psychology can and should
search for the link in the mind between sensation and representation
It could be that all that
can be said is that sensations can produce representational effects, that it is
a property of the human brain, in the same sense that it is a property of the
brain to have a representational system
"Nothing principled
precludes the chance that highly valued mental states are sometimes the effects
of (literally) nonrational causes. Cognitive psychology could have nothing to
say about the etiology of such states since what it talks about is at
most...mental states that have mental causes."
And are so-called
nonrational causes not logical?
Fodor has at least the
virtue of frankness
He admits that philosophy
of mind in the guise of cognitive psychology is highly restricted and not a very
comprehensive picture of mind
So what then is it about?
The time it takes to
solve problems?
The order in which we go
about solving problems?
In general, specific and
specialized hypotheses of this sort?
Other philosophers of
mind leave room for nothing but such issues, e.g., Dennett, whereas Fodor admits
that mind is wider
"(C)ognitive psychology
is about how rationality is structured, viz., how mental states are contingent
on each other...Cognitive explanation requires not only causally interrelated
mental states, but also mental states whose causal relations respect the
semantic relations that hold between formulae in the internal representational
system. The present point is that there may well be mental states whose etiology
is precluded from cognitive explanations because they are related to their
causes in ways that satisfy the first condition but do not satisfy the second."
As an example of
"causal-but-noncomputational relations between mental states" Fodor offers the
case of a person that chooses some arbitrary sign to remind him to do something
or other
He concludes that there
is a connection between the two states but that it is not a logico-semantical
connection
But in fact the sign
chosen, although seemingly arbitrary, has a metaphorical value which is
internally coded and which connects semantically with the state which is the
effect he wants to achieve (be reminded of something)
"I think it's likely that
there are quite a lot of kinds of examples of causal-but-noncomputational
relations between mental states. Many associative processes are probably like
this, as are perhaps, many of the effects of emotion upon perception and belief.
If this hunch is right, then these are bona fide examples of causal relations
between mental states which, nevertheless, fall outside the domain of
(cognitive) psychological explanation. What the cognitive psychologist can do,
of course, is to specify the states that are so related and say that they are so
related. But, from the psychological point of view, the existence of such
relations is simply a matter of brute fact; explaining is left to lower-level
(probably biological) investigation."
Associative processes
are, to my mind, prime examples of the language of thought
Affects accompany
propositional states and of course have effects upon them, and vice versa
propositional states have effects upon affects, e.g., I am depressed because of
something that I know, I entertain a consolatory proposition, I feel better even
if only momentarily: depression can return but only as a consequence of
propositional content
He cannot
compartmentalize mind in this manner, he cannot lawfully say that there are pure
computational mental states, except on the mistaken assumption that mind can be
reduced by analogy to the condition of a computational organism
"The universe of
discourse whose population is the rationally related mental events constitutes,
to a first approximation, the natural domain for a cognitive psychology."
FN: "I am assuming--as
many psychologists do--that cognitive processes exploit at least two kinds of
storage: a `permanent memory' which permits relatively slow access to
essentially unlimited amounts of information and a `computing memory' which
permits relatively fast access to at most a small number of items"
Fodor,
Representations: Philosophical Essaqys on the Foundations of Cognitive Science
(1981)
If Fodor and others are
analytical philosophers of mind, then we must distinguish between two phases in
analytical phil-mind: the first analytical phil-mind, which in essence is a
denial of psychology; and the second analytical phil-mind, in which psychology
is brought back in and with it introspection under various guises,
justifications, and so on
According to Fodor, in
the early 1960s dispositionalism was the analytical theory of choice against the
old psychological model (the Roustan model)
The Roustan model beat
dispositionalism hands down on simplicity, explanatory power, and predictive
success, e.g., how could you go from headache behaviour to headache itself?
Assuming mental
interaction--perception and memory or logic, logic and memory, and so on--it did
not necessarily manifest itself in physical behaviour
Behaviorism and
dispositionalism could in no way or manner or form constitute a wholesale
refutation or denial of psychology
There are two forms or
versions of physicalism
Type physicalism
necessarily implies that mental states could only be realized in the brain
Token physicalism
admitted the possibility of multiple realization
The argument ran somewhat
like this: a specific pain was the same as a specific brain state, but another
specific pain could have its realization in a brain of another sort of material
[This argument is
wrong-headed
The specificity of a pain
or a qualia cannot be argument for that machines can feel
Further, a specific pain
necessarily implies the type pain and, as per Fodor, this precludes multiple
realization]
Type physicalism leads
directly to neurophysiological theories of mind
But in this respect it is
necessary to distinguish between those that hold to identity, in one version or
another, without giving up the autonomy of mental processes, and those that
posit eliminativism or reductionism
But let us proceeed with
Fodor's argument
Since mind is not
identified with a specific type of brain, then mind is cognition
Token physicalism leads
directly to cognitive processes
Cognitivism agreed with
the physicalist position on the ontological autonomy of mental particulars
On the other hand,
cognitivism and behaviorism agreeed on the relational nature of mental events
The assumption here is
that behaviorism assumes a relation between mind and body
What was needed to bring
these two strands together within cognitivism was funcionalism or the
mind/machine analogy
Functionalism then
embraced autonomous cog-processes and the relational property of mind
Functionalism was
cognitivism as a fusion or combination of the best features of physicalism and
behaviorism
Functionalism finally
managed the reconciliation of cognitivism and materialism
Fodor seems to recognize
that Putnam indeed proposed the functionalist analogy in his article "Minds and
Machines" (1960)
We must assume that
cognitivism was born and bred in psychology, i.e., that it was a branch of
psychology
Functionalism has three
defining features
It is relational in two
senses: in the sense of the interaction of mental states and in accepting
propositional attitudes as a relation of a belief and a proposition
Belief of course implies
self
Functionalism holds that
mental particulars are causes
"The intuition that
underlies functionalism is that what determines which kind a mental particular
belongs to is its causal role in the mental life of the organism"
The reasoning here is
that psychology necessarily entails categories
Functionalism claims that
it is only as causes that mental events can be categorized
The only psychological
properties are functional properties, i.e., those that have effects
Finally and crucially,
because without this the whole program founders, cog-processes can be realized
and studied in mechanisms other than the human brain
This means basically that
if we study the way a computer reasons, we can elicit information on the way the
mind works
Fodor, however, is
critical of pure functionalism, and this is important because what he is driving
towards in thse essays is a vindication of folk psychology
"And while it is arguable
that what makes a belief--or other propositional attitudes--the belief that it
is, the pattern of (e.g. inferential) relations that it enters into, many
philosophers (I am among them) find it hard to believe that it is relational
properties that make a sensation pain rather than an itch, or an after-image a
green after-image rather than a red one"
Let us put our ducks in a
row as per Fodor
The old traditional
psychology--what I call the Roustan model--is that mind is constituted by
propositional attitudes
Propositional attitudes
have contents and are causes, i.e., we act on what we know
Propositional attitudes
are the essence of awareness
"By saying that
propositional attitudes have semantic properties, I mean to make the
unpretentious point that beliefs (for example) are the kinds of things that can
be true or false, and that there is typically an answer to the question of who
or what a given belief is true or false of (who or what it is a belief about).
By saying that propositional attitude contexts are opaque (intensional), I mean
to make the familiar point that such principles of inference as existential
generalization and substitutivity of identicals apparently do not apply to
formulae occuring unembedded"
What Fodor is trying to
do is to reconcile propositional attitude psychology and functionalism
For the first analytical
theory of mind propositional attitudes were a dirty phrase
You could not avoid them,
but they made introspection useless
We knew what we believed
but what we believed could be perfectly illogical
I myself call this the
awareness problem, and I shall get to that
Fodor's argument is that
propositional attitudes have content and are semantical and intensional
Similarly, functionalism
is both semantical and intensional
Since functionalism
entails symbol-manipulation, then we can infer that mind is also
symbol-manipulation
But mind also has
contents, i.e., awareness
Awareness or contents are
causes in prop-att psychology
However, functionalism
does not posit awareness and is neutral about causes
Cognitivism is
psychological, hence partial to the identification of prop-att's and causes
Functionalism seems then
useless to cognitivism
What Fodor wants to prove
is that functionalism does provide a theory of mental contents, i.e., of
awareness and prop-att's
"Here's where we've got
to: what we need--and what functionalism tolerates but does not, per se,
provide--is a theory of what it is for mental states to have propositional
content"
"This is the theory:
(a) propositional
attitudes are relational.
(b) Among the relata are
mental representations (often called `ideas' in the older literature).
(c) Mental representation
are symbols: they have both formal and semantic properties.
(d) Mental
representations have their causal roles in virtue of their formal properties.
(e) Propositional
attitudes inherit their semantic properties from those of the mental
representations that function as their objects."
"Questions like the
following are in the forefront: If there are mental representations,
where--ontogenetically speaking--do they come from? If mental representations
have both semantic and causal properties, how do the two connect? If we are
going to take the notion of propositional content seriously, how will that
affect what we say about the position of psychology among the other sciences?
And so on."
"If the present views can
be sustained, then it is mental representations that have semantic properties
in, one might say, the first instance; the semantic properties of propositional
attitudes are inherited from those of mental representations and, presumably,
the semantic properties of the formulae of natural languages are inherited from
those of the propositional attitudes that they are used to express. What we need
now is a semantic theory for mental representations; a theory of how mental
representations represent"
Let us take stock here
What Fodor has done is to
recover mind for philosophy
But mind in the guise of
cog-processes organized according to scientific cause-and-effect symbolic
sequences
This is not exactly the
Roustan model, but it is closer to it than behaviorism or dispositionalism
The first analytical phil-mind
retained propositional attitudes from the Roustan model until Wittgenstein
simply got rid of them
Fodor also retains them
but, whereas propositional attitudes were the source of the intensionality of
mind in the first analytical phil-mind, in Fodor propositional attitudes are
determined cognitive processes or the result of them
Functionalism applies to
the analysis of propositional attitudes
And in addition, Fodor
admits the existence of qualia, which is definitely psychological
Fodor claims that to
explain propositional attitudes means to explain cog-processes such as
perception
And since perception is
awareness, then perception implies that we are aware and we can derive knowledge
from introspection
Propositional content
determine propositional attitudes
And if propositional
attitudes are psychological, the propositional content are also the object of
psychology
The crux of the matter is
that functionalism is about symbols
How can mind know the
symbolic processes of functiionalism?
Fodor's answer is that
symbols are representations
What we have in mind are
not images but symbols
We have a language of
symbols in mind
"Now here is one story
about the frequency effect. There is in your head a mental lexicon: a list of
such of the words in your language as you know. When you are asked whether a
letter string is a word you know, you search for the letter string in this
mental lexicon...(T)he words in the mental lexicon are listed in order of their
frequency and they are searched in the order in which they are listed"
Fodor, "Observation
reconsidered" (1984)
According to Quine and to
Churchland via Quine, observation is not theory neutral
Quine argues in Fodor's
words: "It is thus unclear how two theories could dispute the claim that P
(since the claim that P means something different in a theory that entails that
P than it does in, say, a theory that entails its denial)"
Non-theory-neutrality
means that perception is inferential
Fodor claims a strong
distinction between inference and observation
Inference implies
attachment to theory whereas observation implies attachement to the world
In arguing against Quine/Churchland
Fodor as usual appeals to ignoratio elenchi, as do all philosophers
"What happens in
perceptual processing, according to this account, is that sensory information is
interpreted by reference to the perceiver's background theories"
This can be read as that
specific memory is a theory
Further he argues that if
perception were dependent on theory, then knowing an illusion or the cause of an
illusion we wouldn't entertain it, but in fact "knowing that they are illusions
doesn't make them go away" (in specific reference to Müller-Lyer)
In sum, theories make
little difference to how we perceive
And then his main
argument: the "idea that perception is a kind of problem solving does not, all
by itself, imply the theory-dependence of observation...To get from a
cognitivist interpretation of perception to any epistemologically interesting
version of the conclusion that observation is theory dependent, you need not
only the premise that perception is problem solving, but also the premise that
perceptual-problem solving has access to ALL (or, anyhow, arbitrarily much) of
the background information at the perceiver's disposal", which doesn't square
with what he calls "perceptual implasticities"
Fodor argues: "sensation
is responsive solely to the character of proximal stimulation and is
noninferential. Perception is both inferential and responsive to the perceiver's
background theories...Sensory processes can't be inferential because they have,
by assumption, no access to background theories in light of which the distal
causes of proximal stimulation are inferred...to split the difference...you need
to postulate a tertium quid; a kind of psychological mechanism which is both
encapsulated (like sensation) and inferential (like cognition)..."
He ends up with a modular
theory in which perception is both inferential and encapsulated, but is not
continuous with cognition
Cognition connotes
theory-laden or non-theory-neutrality
Fodor in this article is
committed to a compartmentalized understanding of mind for the sake of the
objectivity of observation and perception as opposed to their sensitivity to
beliefs other than those for which they provide grounding
Interestingly, he does
agree to a distinction between observation and belief-fixation, based once again
on Müller-Lyer
"Belief-fixation, unlike
the fixation of appearances--what I'm calling observation--is a conservative
process; to a first approximation, it uses everything you know"
And you can start the
work of critique from here: modules so-called do not work if they do not work
synchronously with all basic-cog's
Try as he might Fodor
cannot come up with a solution to the distinction he himself makes: "modules
offer hypotheses about the instantiation of observable properties of things, and
the fixation of perceptual belief is the evaluation of such hypotheses in light
of the totality of background theory"
Additionally, he had
written: "it may be that some of (the) semantic properties (of sentences) are
determined by the character of their attachment to the world (e.g., by the
character of the causal route from distal objects and events to the tokening of
the sentence or the fixation of belief)"
He was preparing the way
for the distinction, which is not easily inferrable in his other writings
What he in effect is
saying is just the contrary of what he started with: that seeing is believing
Fodor, "Fodor's Guide to
Mental Representation: The Intelligent Auntie's Vade-Mecum (1985)
This essay is about
functionalist psychology
It is about how mind
thinks, how knowledge is possible, how our beliefs are formed, and so on
From Representations
(1981):
"The intuition that
underlies functionalism is that what determines which kind a mental particular
belongs to is its causal role in the mental life of the organism"
But were this so, we
could only classify mental particulars as either causes or non-causes, and this
is patently untrue given that we know a perception from a thought from an affect
Fodor defines himself as
a realist about prop-att's
He accepts what is
sometimes called prop-att psychology
There is also something
called standard realism (SR)
This is what he first
tries to describe
SR involves two distinct
networks
There is a network of
beliefs/causes
These are mental states
The other network is the
semantical inferential network in which propositions emerge as the objects of
propositional attitudes
On semantical see
Representations
In sum, SR posits
propositional attitudes and propositions with semantical content
Propositional attitudes
are causal networks
Propositions originate in
inferential systems
There are isomorphisms
between the causal network and the inferential system
"Notice, however, that
while this gives a Functionalist sense to the indviduation of propositional
attitudes, it does not, in and of itself, say what it is for for a propositional
attitude to have the propositional content that it has. The present proposal is
to remedy this defect by reducing the notion of propositional content to the
notion of causal role"
"In short we can make
non-arbitrary assignments of propositions as the objects of propositional
attitudes because there is this isomorphism between the network generated by the
semantic relations among propositions and the network generated by the causal
relations among mental states...Now, though they are usually held together, it
seem clear that these claims are orthogonal. One could opt for monadic mental
states without functional-role semantics; or one could opt for functional-role
semantics together with some nonmonadic account of the polyadicity of the
attitudes"
What Fodor pretends to
give is an explanation of how prop-att's are mapped on to inferential processes
and what the inferences are made of
Roughly, this is
referring to the relation between thought and brain, mind and matter
SR apparently does not
contemplate the intermediation of representations
His own explanation is
the representational theory of mind or RTM
"Acccording to the
canonical formulation of (RTM): for any organism O and for any proposition P,
there is a relation R and a mental representation MP such that: MP means that
(expresses the proposition that) P; and O believes that P iff O bears R to
MP...As compared with SR, RTM assumes the heavier burden of ontological
commitment. It quantifies not just over such mental states as believing that P
and desiring that Q but also over mental representations; symbols in a `language
of thought'"
What Fodor introduces
with RTM is representation
Representation is mising
in SR
I presume that what he
means is that SR does not have a clear notion of mental content
It does not in itself as
a theory argue for words, images, or what have you
From here on in his
arguments are for a language of thought which is symbolically represented in
mind
How can thought be so
productive?
Fodor recurs to the
speech acts/mental acts analogy I have seen in Searle
Language is productive
because its assertions are symbolical
We can assume that mind
is productive because it works with a language of mental symbols
The next argument has to
do with the process of thought and how it connects with propositional attitudes
Propositional attitudes
necessarily involve a theory of thought
This is where Fodor
offers a mind/matter bridge, supposing that prop-att's are mental states and
mental states are brain states
Before he gets there
Fodor does some simplistic historical speculation
The philosophy of mind of
British empiricism was a form of RTM
It assumed prop-att's
related to mental images "the latter being endowed with semantic properties in
virtue of what they resembled and with causal properties in virtue of their
associations. Mental states were productive because complex images can be
constructed out of simple ones"
However, associationism
is not rational, which Kant criticized
And that is why, Fodor
says, everybody went behaviorist
And what he claims he is
trying to do is to connect prop-att's with rational processes
"Computers show us how to
connect semantical with causal properties for symbols...You connect the causal
properties of a symbol with its semantic properties via its syntax. The syntax
of a symbol is one of its second-order physical properties...Because, to all
intents and purposes, syntax reduces to shape and because the shape of a symbol
is a potential determinant of its causal role, it is failry easy to see how
there could be environments in which the causal role of a symbol correlates with
its syntax...But...we know from formal logic that certain of the semantic
relations among symbols can be, as it were, `mimicked' by their syntactic
relations; that, when seen from a very great distance, is what proof-theory is
about. So, within certain famous limits, the semantic relation that holds
between two symbols when the proposition expressed by the one is implied by the
proposition expressed by the other can be mimicked by syntactic relations in
virtue of which one of the symbols is derivable from the other...(C)omputers...are
environments in which the causal role of a symbol token is made to parallel the
inferential role of the proposition that it expresses...Computers are a solution
to the problem of mediating between the causal properties of symbols and their
semantic properties. So if mind is a sort of computer, we begin to see how you
can have a theory of mental processes that succeeds where associationism (to say
nothing of behaviorism) abjectly failed; a theory which explains how there could
regularly be nonarbitrary content relations among causally related thoughts.
"But patently,
there are going to have to be mental representations if this proposal is going
to work. In computer design, causal role is brought into phase with content by
exploiting parallelisms between the syntax of a symbol and its semantics. But
that idea won't do the theory of mind any good unless there are mental symbols;
mental particulars possess semantic and syntactic properties. There must be
mental symbols because, in a nutshell, only symbols have syntax, and our best
available theory of mental processes--indeed, the only available theory of
mental that isn't known to be false--needs the picture of mind as a
syntax-driven machine"
Let us do a rehash
Propositional attitudes
necessitate representation
Representations are
symbolic
Symbols entail syntax and
syntax is physical
The physicality of syntax
provides the bridge between propositional attitudes and the symbol-using
cognitive system which provides the objects of prop-att's
All of this means that
what he calls a theory of thought is also a theory about the mind/matter
relation
Can we really make grand
claims about mind from the way we have computers work?
How do we know that the
computer syntax is like the syntax of squiggles?
Does the computer explain
anything that cannot be explained without the computer?
I will grant that the
computer analogy provides "leads" but not "grounds"
Finally, any full-blooded
functionalist must of necessity be a believer in and a partisan of artificial
intelligence, for it is only in the belief that machines can be entirely like
mind that we can infer anything about mind from machines
"...(T)he question of the
extent to which RTM must be committed to the `explicitness' of mental
representation is one that keeps getting raised...According to RTM, mental
processes are transformations of mental representations. The rules which
determine the course of such transformations may, but needn't, be themselves
explicitly represented. But the mental contents (the `thoughts', as it were)
that get transformed must be explicitly represented or the theory is simply
false"
None of the above
guarantees that thought will be truthful or error-free
"I remarked above that
the two characteristic tenets of SR--that the attitudes are monadic and the the
semanticity of attitudes arises from isomorphisms between the causal network of
mental states and the inferential network of propositions--are mutually
independent. Similarly for RTM; it's not mandatory, but you are at liberty to
combine RTM with FR semantics if you choose"
So it turns that RTM does
not correct at least one fundamental deficiency of SR
"Functionalism guarantees
that mental states are individuated by their causal roles; hence by their
position in the putative causal network. But nothing guarantees that
propositions are individuated by their inferential roles"
"Individuate" could mean
explain, classify, or determine
Take your pick
"Quantify over" is to
give a material or "extensional" explanation
FR posits that logic
determines propositional attitudes but "everybody is at least a little
irrational"
This argument is to say
the least too humble by half and show the essential vacuity of Fodor's abstract
verbiage
He also has a more
abstract argument
The beliefs P and [P v (Q
v ~Q)] are different, but logically the propositions P and [P v (Q v ~Q)] are
equivalent
In sum the fact that
logic recommends both propositions does not necessarily mean that they are
beliefs in any one
Hence, RTM dos not
necessarily involve or include FR
Finally, then, we have a
"syntactic theory of mental operations...But a theory of the intelligence of
thought does not, in and of itself, constitute a theory of thought's
intentionality...If RTM is true the problem of the intentionality of the mental
is largely--perhaps exhaustively--the problem of the semanticity of mental
representations. But of the semanticity of mental representations we have, as
things now stand, no adequate account"
Folk psychology
See Dualism
Formal language
"An uninterpreted system of signs. The
signs are typically of three sorts: (1) variables, for example, sentence
letters p, q, r, s; (2) connectives, for example, V, &, -->, by which
signs are joined together; and (3) punctuation devices, such as brackets,
to remove ambiguity. There are also formation rules telling how to string
signs together to form well-formed formulae, and transformation rules
telling how to transform one string of signs into another...[If] the
transformation rules are made deduction rules, then the formal language
has been interpreted as a system of logic.
"Distinction must be made between
formal languages (uninterpreted systems of marks) and artificial languages
which are, however, not natural languages as vernacular English is)."
(Flew)
Formal system
"Formal system (or theory). Any set of
axioms and/or rules of inference written in some specified formal language
L. The axioms will be closed wffs of L, and rules of inference (or
transformation rules) are rules according to which proofs can be
constructed out of wffs of L." (Flew)
Formalization
Whereas to specify means to individualize in explaining, to formalize is explain by means of relations like similarity and contrast.
The propositional calculus
Rules (either formation or inference): if x and y are wffs, then the following propositions are also well formed
(1) denial of x
(2) x and y
(3) x or y
(4) if x then y
Now from the above (without assuming that x and y are wffs)
(5) if (2), x and y are wffs;
(6) if x and (x-->y), then y (modus ponens);
(7) if x then y, when not x then not y (modus tollens);
(8) If not x and not y, then not x or y;
(9) if x or y, when not x then y.
Obviously, then, the propositional calculus has nothing to do with the linguistic equivalent of strings, because if "this is a chair" is the linguistic equivalent of a wff, then it cannot be that "this is not a chair".
As the derivation of formal logic from the application of intuitive logic to itself, logic is the use of variables in lieu of propositions and the formulation of axioms and rules to apply to variables. As the application of formal logic to propositions, logic is mainly the conversion of propositions into variables and the application of axioms as rules either to derive variables which in turn can be converted into propositions or to determine whether propositions conform to logical rules. Finally, logic is also the derivation of formulæ from the application of formal logic to itself, that is, the use of variables and rules to derive different valid combinations of variables (wffs).
How formal logic operates
Formal logic represents terms and relations.
Operations are propositions which affect representations.
Representation
Assuming a proposition, an operator can deny, but there is no specific symbol for affirmation: it is expressed in formal logic as a variable, although a case could be made for the existential quantifier as essentially an affirmation in which the concept is made explicit. In other words: concept is: "there is chair", "there are chairs". "this is a chair". The existential quantifier says: "there is an x such that if there is an object with chair-properties it is x".
Representation/operation
In relation to complex propositions, logical operators function in two ways: (a) they represent logical relations within propositions; (b) they allow intuitive logic to determine whether the relations within existing propositions are logical or not.
Operations
Formal logic is a system of notations which includes variables and rules. The rules are expressed as operators or functions. Operators permit the derivation of propositions, simple or complex, from other propositions. They also serve to determine the relations between propositions.
"Operator. That which effects a [logical] operation. In logic it is usually expressed as a symbol. Corresponding to each function on objects there is a symbolic operation effected by the symbol for that function...The truth-functional operators and quantifiers are termed logical operators. The truth-functional operators are also called sentential operators because when applied to sentences, they yield another sentence." [Flew]
[The reference seems to be to the distinction between intuitive and formal logic. Formal logic works with intuitive logic and symbols, as in inferring that conjunction and exclusive disjunction cannot be applied to the same pair of propositions.]
In making a statement logical operators are at work.
This is self-evident in that affirmations or propositions are logical operations: various symbolizable or notational operations go to making an affirmation or formulating a proposition. In formal logic, operators determine what are wffs and not wffs. The rules of deductive systems permit the elaboration of wffs. But there is some questions as to whether wffs are true in the epistemic sense.
I cannot grasp the idea of a wff that is not also valid.
Affirmation and negation and in-between stances apply to simple propositions and to complex propositions.
Simple propositions are usually concepts: propositions which say that something is or is not, although concepts can also be definitions, such as "justice is fairness for all" or "democracy is one person/one vote". Complex propositions involve relations between entities and properties.
Complex propositions also establish relations between simple propositions, between simple and complex propositions, and between complex propositions.
Logical rules apply to all the types of complex propositions.
Since propositions have truth values, then it can be said that operators establish truth-values and can derive truth-values.
Therefore, operators can be termed truth-functional operators. Operators are means of justification and criteria of validation.
All the propositions that apply to operators apply equally well to the concept of basic-cog's in intuitive logic.
Formal system
Todo sistema formal para hacer inferencias o deducciones consta de símbolos y de reglas. En el supuesto de que las operaciones dentro de este sistema se puedan hacer de manera automática con sólo percibir los símbolos y sus posicions respectivas, se puede decir que son reglas tipográficas, según Hofstadter. Pero entonces, en cuanto anteponer un no a una expresión en un lenguaje natural equivale a su negación, también podríamos describir a la gramática como reglas tipográficas. El concepto de "reglas tipográficas" puede servir para subrayar el carácter mecánico de la lógica, pero no es, a mi entender, muy apropiado. Es hasta de dudarse que las llamadas reglas tipográficas funcionen de la manera vacía y automática que les atribuye Hofstadter.
Con los dos elementos de todo sistema se pueden producir teoremas o cuerdas (strings). En las matemáticas, teoremas son proposiciones verdaderas (válidas). Un axioma es una cuerda que se presupone o con la que se arranca para derivar otras cuerdas. Un axioma por ende es un teorema elemental. Aplicando las reglas o axiomas a los axiomas se logran más cuerdas que se llaman derivaciones. Entre los axiomas los hay que excluyen ciertas derivaciones.
Todo sistema deductivo implica la existencia de un `procedimiento decisorio' (decision procedure) para determinar la validez de los teoremas.
`Procedimiento decisorio' viene entonces siendo lo mismo que `prueba' o `método de prueba'. El procedimiento decisorio básico de cualquier sistema se puede expresar de la manera siguiente: suponiendo la cuerda `x' y suponiendo un sistema `s' que contiene o puede producir un número determinado de cuerdas o teoremas, si la cuerda `x' es una de las cuerdas del sistema `s', entonces `x' es un teorema del sistema `x', y a la inversa: si la cuerda `x' no es parte del sistema `s', entonces no es un teorema del sistema `s'.
Foundationalism
Foundationalism is that all philosophical thought comes down to abstract choices from basic alternatives about fundamental issues.
Since such choices are neither apodictic nor necessary, they can be considered equally rational. Some foundational claims are: that rational statements can be reliable even if no wholly accurate definition of reason exists; that science gives or does not give an accurate account of nature; that mathematics are a fallible but basic tool of science; that the unity of self is a bundle of perceptions or that it is an intuitive fact that cannot be pinned down in awareness; and that despite the inaccuracy of language, we can rely on it for our everyday transactions, for scientific communication, and for the work of philosophy.
A possible definition of foundational concepts or propositions is that they are undecidable.
Instances of the propositions are:
--self comes before world or world before self;
--being precedes and determines knowledge or knowledge defines being;
--God exists or God does not exist;
--we are free or we are determined;
--behaviour includes thought or thought is not a form of behaviour.
In other words, we can take either option for there is no way that either option can be refuted.
Foundationalism is the claim that it is valid to choose between un-decidable propositions concerning circular concepts.
Frege
(A) From M. Dummett's
Origins of Analytical Philosophy (1993)
Pages 5-6:
"An epistemological
enquiry (behind which lies an ontological one) is to be answered by a linguistic
investigation.
"No justification
for the linguistic turn is offered in Grundlagen: it is simply taken as
being the most natural way of going about the philosophical enquiry. And yet, as
his philosophy developed, Frege became more and more insistent that thoughts,
and not the sentences that express them, formed his true subject-matter. Natural
language came to appear to him more of an obstacle than a guide in logical and
philosophical enquiries. Especially was this so after his realisation that he
had after all no satisfactory solution to Russell's paradox, and that he had
failed...to set number theory...on indisputably firm foundations. This occurred
in August 1906; and he thereafter rejected his whole former conception of
logical objects, including classes (extensions of concepts), blaming language
for the illusion of their existence generated by the possibility of forming
apparent singular terms of the form "the extension of the concept F". Thus, in
November 1906 he wrote to Husserl that "The main task of the logician consists
in liberation from language", and in the article "Erkenntnisquellen", completed
the last year of his life, he said that "a great part of the work of the
philosopher consists in...a struggle with language".
Pages 6-7:
Frege: "The sentence can
be regarded as an image of the thought in that to the relation between the part
and the whole within the thought there by and large corresponds the same
relation between the part of the sentence and the sentence"
Dummett: "The
discernment of constituent senses as parts of a thought is parasitic upon the
apprehension of the structure of the sentences expressing it"
"The thought is grasped
in grasping the semantic properties of the sentence: to speak of the structure
of the thought is to speak of the semantic interrelation of the parts of the
sentence"
[But we can understand
unstructured sentences
Therefore, thought has
nothing to do with grammatical structure]
Pages 8-9:
"Frege held that it is
the thought that is primarily said to be true or false, the sentence being
called true or false only in a derivative sense; and, since for Frege the
reference of the sentence is its truth-value, this means that it is the sense of
the sentence that primarily has the reference, and the sentence only
derivatively...In practice, however, Frege never conformed to this order of
priority when expounding the distinction between sense and reference. He never
first introduces the notion of sense, subsequently explaining reference as a
feature of senses: he speaks first of the expression as having reference, and
proceeds either to argue that it also has a sense or to say something about what
its sense consists in. This order of exposition is actually demanded by his
conception of the sense of an expression as the way in which its reference is
given: for it follows from this conception that the notion of sense cannot be
explained save by appeal to that of reference, and so we must have first the
notion of reference. Now if we have the notion of reference before we have that
of sense, we cannot construe reference as a property of the sense, but only of
the expression. It follows that Frege's thesis that it is the sense to which the
reference is primarily to be ascribed is incorrect."
[This argument seems to
be saying: Frege held thesis x and he held thesis y, thesis x contradicts thesis
y and thesis y is incorrect, therefore Frege is wrong, but in fact both theses
are Frege's so he is both right and wrong]
Pages 15-6:
"Hence, in asking the
question, `What, in general, render a proposition true?', we are presupposing
that the meanings of sentences can be taken as given in advance of a knowledge
of what renders them true or false"
[In point of fact there
is no `general' answer to what renders a proposition true, and it seems obvious
that we must know what a proposition means before we can qualify it as true,
false, valid, or whatever
If I hear someone say
"the white horse ran over the cliff edge" I grasp the meaning of a sentence
which may or may no be true and in grasping its meaning I am also grasping the
conditions for it to be true, and that is that!!!]
Page 23:
"On Frege's view,
thoughts and their constituent senses form a `third realm' of timeless and
immutable entities which do not depend for their existence on being grasped or
expressed.
"The practical
consequence of this ontological doctrine was the rejection of psychologism. If
thoughts are not mental contents, then they are not to be analysed in terms of
individual mental operations. Logic and theories of thought and of meaning are
thus to be sharply demarcated from psychology. Although Frege asrrived at this
position quite independently, he was far from from unique in holding it. Bolzano
had drawn a distinction between the subjective and the objective in almost the
same terms are Frege, and had anticipated his complaint that Kant fails to
maintain a clear distinction between them. He had made the same distinction as
Frege between subjective and ibjectiver ideas, or ideas possessed and ideas in
themselves: this is precisely Frege's distinction between ideas and senses. He
had likewiswe distinguiashed between propositions as being thought and
propositions in themselves, crediting Leibniz and Herbart with having previously
made a parallel distinction."
Page 36-7
"Frege, during his early
period, that is to say, up to 1890, drew no distinction between signification
and thing signified; he used the term `indifferently' for both. He therefore
drew the consequence that when an empty singular occurred in a sentence, that
sentence was devoid of content: if a part lacks content, the whole must lack
content, too. From 1891 onwards, however, he distinguished sense and reference
within his former undifferentiated notion of content; henceforward he had this
distinction by means of which to explain the matter. An empty name, though it
lacks a reference, may still possess a sense. A sentence containing it cannot be
true or false, since, if a part lacks reference, the whole must lack reference,
and the reference of a sentence, on Frege's theory, is a truth-value; but the
sentence will still express a thought if the name has a sense. There is thus no
simple answer to the question whether a speaker who uttered such a sentence
would thereby have said anything: he expressed a thought, but he said nothing
either true or false."
Page 53:
"Since the sense of an
expression is in all cases the way in which its referene is given, deciding
what, and what kind of thing, constitutes the reference of a given expression is
a crucial first step towards characterising its sense, which is required to take
the form of a means by which that reference may be given to a speaker of the
language"
[These statements
contradict the argument on page 36
They also seem partly to
contradict pages 8-9]
Pages 58-9
"Frege would not have
said that the sentence (the King of France is bald) was nonsense, but that it
had sense, and so expressed a thought. But he would also not have said that it
was false, since he would have regarded the absence of reference for the
constitutent "the King of France" as depriving the whole of reference, and thus
of truth-value; the thought expressed was neither true nor false."
"Frege called what is
expressed by a sentence a `thought', and held that truth and falsity are
predicated of thoughts absolutely: a thought could not, for him, be true at one
time and false at another, or true for one subject and false for another, but it
is simply true or simply false."
On page 59:
Sentences can have or
not have sense
It is assertions that
are true or false
For Husserl and Frege
sentences can have different senses but the same reference, as in the phrases
"the victor at Jena" and "the loser at Waterloo"
It is not the sense of
these phrases that matter but their reference
Page 63:
"Frege believed that the
only access we human beings have to thoughts is through their verbal expression;
so the question how we grasp thoughts resolves into the question of how we
understand sentences...The sense of an expression is the way its reference is
given to us; the reference of the words in a sentence together serve to
determine its truth-value, so that to grasp the thought it expresses is to grasp
the condition for it to be true"
Page 81:
"[Frege] believed that
natural language contains expressions possessing sense but lacking reference:
but he believed also that this is a grave defect of natural language, which
requires correction before we have at our disposal a language within which we
can reason with an assurance of the validity of our inferences"
Page 81:
"Russell plainly
believed that, once he had distinguished between sense and reference, Frege was
powerless to counter an attach from idealism"
Page 96:
"The `third realm' [is
the realm] of thoughts and their constituent senses, which is...accessible to
all in common, but whose contents are immutable and immaterial, and do not act
on the senses or on each other, but which we can grasp"
There are then three
realms: the inner world of ideas, the external world, and the `third realm'
The sense of thought is
the third realm, which is timeless and immutable
Psychology cannot reveal
thought
There is an opposition
between psychology and logical thought
Mind contains ideas
which are subjective and incommunicable, whereas thought is objective and
communicable
The stream of thought is
constituted by ideas
[In connection with the
idea that thoughts are unchanging, Dummett states that according to Frege: "They
do not act causally upon other objects"
I am not clear as to
what he means
If thoughts are logical,
then they must interact
Ideas are communicable
Suppose two persons
disagree on an impression
There has to be a
transaction of one sort of another: perhaps Quine's notion of marginal
"sacrifices"
Otherwise there is no
communication, but this would be irrational
It happens that such
irrationalities transpire, but this is even more damning for any
meaning/language theory]
Page 98:
"As for whether
perception involves judgement, or only the apprehension of a thought without
judging it to be true, that depends on whether perception yields knowledge or
not, since Frege explicitly...held that knowledge issues in judgements; since he
also accepted sense-perception as a source of knowledge, the natural conclusion
is that, at least in the normal case, perception involves judging some state of
affairs to obtain, rather than merely entertaining the thought that it does"
Page 103:
"But it is difficult to
see how it can be maintained that no occurrent notion of understanding is
required: for it is possible to be perplexed by a sentence on first hearing,
through a failure to take in its structure, and to attain an understanding of it
on reflection"
And Frege writes:
"When we use the word
`integral', for example, we are always conscious of everything that belongs to
the sense of this word?"
And:
If we tried to recall
everything belonging to the sense of this word, we should make no headway"
[It seems to me that all
these statements involve introspection
Awareness is not
introspection: it is the presence of the world or of thought to mind
When the self is
explicit in awareness, then awareness is consciousness. and it seems to me that
in these cases the self is made explicit]
Page 107:
Sense, but not
reference, can be grasped directly
"We need to know what
exactly it is to grasp a sense, because sense is distinguished from reference
prercisely by the fact that it can be grasped--can be apprehended directly,
rather than in one or another particular: were it not so, there would be no
place for a notion of sense, as distinct from reference, at all...Our grasp of
sense consists, therefore, not in the ability to determine the truth-values of
sentences, or to recognise them as having one or other truth-value, but in the
knowledge of what renders them true or false.
"We thus cannot,
after all, extract from Frege a clear account of what it is to grasp a sense;
and we need to know this, in particular, in order to assess the thesis that
sense-perception involves the grasp of a thought or sense...But it is only a
theory that anything resembling meaning plays a role in the perception of a
physical object: to support that theory, it has to be argued that a grasp of
meaning is an ingredient in the (psychological) process of perceiving"
Page 110:
"What can be Frege's
ground for holding that sense-perception involves the grasp of a sense? It is,
presumably, that sense-perception normally requires the awareness of one or more
object, and that we cannot ever simply be aware of an object, in the sense that
our state of awareness can be completely described by indicating the object of
which we are aware: that object must be given to us in some particular way, and
the way in which it is given is always a sense which can be a
thought-constituent. The sense-impression may be of the object, in the sense
that the object gave rise to it, but, being a mere content of consciousness,
does not of itself have the capacity to point beyond itself to the object: only
a sense--a thought-constituent--has such a capacity to point to something as its
referent."
[This quote implies a
distinction between consciousness and sense
But sense or meaning is
precisely what defines awareness
A sense is nothing: an
ability, a use, a grasping, and so on, in other words, nothing, at most a
practice
So when Dummett says
that sense-perception involves a sense, he is saying nothing at all
He could escape this
empty doctrine by defining mental contents as propositions
Perception is a
proposition to the extent that a proposition requires assent or dissent and we
are constantly accepting perception as reliable, we are constantly making
judgements about perception, which is proven by our ability to sense small or
instantaneous changes in perceptions
We can be neutral about
propositions, and we can be neutral about perception as when we see reflection
on a wall and we do not know its source or what it is
Finally, if our thought
is propositional, since propositions, as in perception, do not come to us
expressed in linguistic terms, its form cannot be that of natural language, and
since we mainly either think in words or in other symbols, we must think in
other symbols
Sense then has to be the
grasp of symbols, more than a practice, which does not tells us much
Symbols are not easily
forthcoming either, but at least there is here a territory that can be covered
in different ways, not just logic or logic and language, which is a myth anyway]
The sense of a
perception is the grasp of a sense
Since perception always
involves reference, the grasp of sense includes its reference
Thoughts are either true
or false
Thought and reference
determine the truth value of sentences
The sense of a sentence
is dependent on thought]
Page 115:
"Frege's theory [of
sense-perception] is hobbled by his commitment to the thesis that thoughts are
accessible to us only through language. If this means that we can grasp thoughts
only by understanding sentences expressing them, we obtain a very implausible
theory of sense-perception; but, if we set any such contention aside, we are
left with no explanation of how we grasp those thoughts that open up the
external world to us in perception. But Husserl's theory is not in better but in
worse case. His notion of meaning was not, indeed, connected at the outset with
the senses of words, and so can be thought to be detachable; but that only
underlines the lack of any substantial account of what it is...We do not know
why all noematic sense are capable of being expressed in language; and, although
it is clear that they are detachable from language, we do not know how we grasp
them, or, hence, what exactly the noematic ingredient in an act of sensory
perception is..."
Pp.127-8
"If we identify the
linguistic turn as the starting-point of analytical philosophy proper, there can
be no doubt that, to however great an extent Frege, Moore and Russell prepared
the ground, the crucial step was taken by Wittgenstein in the Tractatus
Logicus Philosophicus of 1922. We have been concerned, however, with the
preparation of the ground. Before the philosophy of language could be seen, not
as a minor specialised branch of the subject, but as the stem from which all
other branches grow, it was first necessary that the fundamental place should be
accorded to the philosophy of thought. That could not happen until the
philosophy of thought had been disentangled from philosophical psychology; and
that in turn depended upon the step that so perplexed Brentano, the extrusion of
thoughts from the mind and the consequent rejection of psychologism. The step
was taken by Frege and by the Husserl of the Logische Untersuchungen, who
had been so deeply influenced by Bolzano, if not, as many have argued, by Frege
himself. Frege was the first philosopher in history to achieve anything
resembling a plausible account of the nature of thoughts and of their inner
structure. His account depended upon his conviction of the parallelism between
thought and language...[H]is strategy for analysing thought was to analyse the
forms of its linguistic or symbolic expression. Although he continued to
reiterate that it is inessential to thoughts and thought-constituents that we
grasp them as the senses of sentences and their parts respectively, it is
unclear that his account of the senses of linguistic expressions is capable of
being transposed into an account of thoughts considered independently of their
expression in words. When philosophers consciously embraced the strategy that
Frege had pursued, the linguistic turn was thereby decisively taken.
"Once the
linguistic turn had been taken, the fundamental axiom of analytical
philosophy--that the only route to the analysis of thought goes through the
analysis of language--naturally appeared compelling. Acceptance of that axiom
resulted in the identification of the philosophy of thought with the philosophy
of language, or, to give it a grander title, with the theory of meaning."
[Dummett agrees with
both Frege and Russell that sense is not a product of a psychological process
But if such is the case,
how can we know what we mean when we say something?
Where would meaning be
if not in mind as an attribute of mind?
Communication, if the
meaning of thought were not a content of mind, would have to rest on some kind
of faith about what belief we can ascribe to someone else
A person could say
anything, but in the absence of belief-ascription, which implies a specific
mental content/process, we would have no basis on which to ascribe belief
Unless I assume he has
qualified a proposition as belief, I have no way of knowing whether he means
what he says or not
If his proposition
implies belief, then we are into how the qualification was made
If not, then what are we
left with?
Just the ability to use
the proposition and this does not imply belief
Dummett argues that the
use of a common language suffices to establish meaning, but this to my mind is
skirting the issue
"The crucial question",
he says, "is whether we should take the public language or the private
understanding of it to be primary"
Still, in what does the
grasp of language by an individual consist?
Dummett says that the
individual understanding of a language is an idiolect (from an analogy with
dialect)
The common language
could consist of overlapping idiolects
This respects the
priority of language over thought
Quine subscribes to a
view of this sort
But Dummett insists that
the common language is the primary reference]
Page 130:
"As Frege perceived, a
complete thought is to be characterised as that which it makes sense to qualify
as true or as false: the connection between sense and truth-value has to be made
from the outset if any plausible answer to the question, `What is thought?', is
to be given"
Page 131:
"The extrusion of
thought from the mind initiated by Bolzano led to what is often termed
`Platonism', as exemplified by Frege's mythology of the `third realm'"
The sense of thought is
the third realm, which is timeless and immutable
Psychology cannot reveal
thought
There is an opposition
between psychology and logical thought
Mind contains ideas
which are subjective and incommunicable, whereas thought is objective and
communicable
The stream of thought is
constituted by ideas
Pages 132-3:
"...[U]nderstanding a
word as expressing a certain concept cannot be explained as consisting in the
word's calling up in his mind a concept with which he has come to associate it,
since there is no such process as a concept's coming into anyone's mind: a tune,
a name, a remembered scent can come into the mind, but a concept is not the sort
of thing of which this can be intelligibly said."
[This argument is based
on the proposition that to have a concept is to know how to apply it: it make no
difference whether, when it is applied, anything comes into the mind in the
manner in which a tune might do so
But it is possible to
not have a concept: to have it yet not know all its different intensions or
connotation]
p.134
"It is because
concepts...cannot be spoken of as coming into the mind as ideas can that they
cannot be described as contents of consciousness; and it is precisely this that
gives the strongest grounds for believing the fundamental axiom of analytical
philosophy, that is, that the analysis of thought both can and must go via the
analysis of the linguistic expression."
Pages 135-6
"How, then, can we get
from the premiss that concepts are not contents of consciousness to the
conclusion that thoughts are not contents of consciousness...[A] concept cannot
exist on its own, nor, therefore, come into the mind on its own, but only as a
constituent of a thought, which, perhaps, can come to mind...But, as we saw, on
Frege's theory it is not merely that a thought which I am entertaining is not a
content of my mind, but a constituent of an immaterial reality external to it;
it is, further, that my apprehension of the thought is not mediated by anything
in my mind: it is, rather, preesented to my mind directly--and yet it is
not a content of my mind. And this conception is not consistent."
Page 136:
"But as we saw, on
Frege's theory it is not merely that a thought which I am entertaining is not a
content of my mind, but a constituent of animmaterial reality external to it; it
is, further, that my apprehension of the thought is not mediated by anything in
my mind: it is, rather, presented to my mind directly--and yet it is not a
content of my mind. And this conception is not consistent"
[An analysis of the
previous arguments suggests that Skorupki's thesis, in the sense that for Frege
the primary philosophical issue is thought and not language, is probably
correct]
Page 139:
"The true ground for
Frege's doctrine, shared by Bolzano and by Husserl, that thoughts and their
constituent senses are not mental contents thus lies in their categorial
difference from mental images and sense-impressions, rather than where Frege
located it, in the objectivity of thought and the subjectivity of the mental."
Page 139:
"A judgement is...an
`advance from a thought to a truth-value'. Judgements, and therefore knowledge,
are accordingly subject to the same constraints as thoughts: if thoughts are
intrinsically communicable, then judgements must be intrinsically communicable,
and hence any knowledge we can have must be communicable"
[If knowledge were
intrinsically communicable, then the myriad components of our everyday
experience would not be knowledge, for in practice it is not possible to
communicate those experiences
However, Frege's concept
of judgement would seem to correspond to what I call the qualification of
propositions
Within his own
nomenclature, judgement would have to correspond to the determination of
reference from the meaning of thought
Therefore, we grasp
reference from sense with or through judgement]
Page 140:
"Frege was right to say
that, for me, the first-person pronoun `I' represents a way in which I am given
to myself in which I cannot be given to anyone else."

"Frege was opposed to
what he called `psychologism'--the interpretation of logic in psychological
terms. Logic is concerned with propositions, and it is therefore important to be
clear what propositions are and what is the status of the terms that make them
up. In Foundations of Arithmetic he laid down that one should ask for the
meaning of a word only in the context or nexus of a proposition. It is
propositions that constitute the fundamental units of meaning. He was later to
say that the sense of a proposition is a thought, so that it is thoughts, in the
form of judgements, which are the starting point for any theory of meaning."
(p.291)
"In his paper `On Sense
and Reference' Frege goes further into questions concerning meaning. He starts
from the observation that `The morning star is the the evening star' and `The
morning star is the morning star' are both true identity statements; the terms
in each refer to the same thing. Frege suggests that one can explain this only
by distinguishing between the sense and reference of expressions. The sense of
a compete proposition is a thought; its reference must be True or False, that
is, its truth-value...Since propositions have the primary role as units of
discourse and their reference is the True or the False, this gives truth and
falsity an important place in the theory of meaning put forward." (Pp.291-2)
(C) [Frege said let's
get to thought from language leaving psychology to one side
Wittgenstein said let's
just look at language and assume it is thought
From Frege's view there
is a parallel between the structure of sentence and the structure of thought
Words per se do not
express thought: if anything thought is what gives words their meaning
Likewise, thought
implies truth or falsehood, which is not the case of words
Since the question of
philosophy is knowledge and knowledge is about what is true and what is false,
then evidently thought is the main question of philosophy
There are of course many
questions on thought
What is it to have a
thought?
What is the structure of
thought?
What is it to have a
thought of a particular thing?
What is a concept and
how is it a component of thought?
In the Frege/Dummett
canon, a concept corresponds to a word, a sentence to a thought, and so it goes]
[In 1884 Frege believed
that sense and reference were inseparable
This implies an
equivalence between meaning and truth
After 1891 he
distinguishes between sense and reference
In either instance of
his thinking, thought is subject to and manifests logic
In the first period
language and logic were coreferential references to thought
In the second period he
separates language from logic, but he retains the thought/logic relation
Since truth involves
logic and reference, this implies a strong connection between thought and
reference: whereas language can have sense without reference, it is not possible
to have thought without reference, and language consequently is not an
infallible guide to thought]

(1848-1925)
Die Grundlagen der
Arithmetik (The Foundations of
Arithmetic, 1884) attempted to show that arithmetic could be derived from
the laws or axioms of a system of formal logic; this involves the so-called
logistic thesis that arithmetic, and thereby mathametics in general, could be
derived from logic." (p.289)
"In any case, in 1931
Kurt Gödel proved that mathematics is incomplete and that there are arithmetical
truths which are unprovable within any consistent logical system. However, the
philosophical insights that came with the attemp[ts to develop that programme
remain.
"There is, first, the
definition of number. Frege's insight is that numbers belong to concepts
(Russell said that they belonged to classes)...Frege asks what it is to say that
the number which belongs to the concept F is the same as that which belongs to
the concept G, and answers...[that]...it is to say that the extension of the
concept equal to the concept F is the same as that equal to the concept G, that
is, the classes that form their extensions have the same number of members.
(Analogously, Russell said that five was the class [concept in Frege] of all
quintets, and a number the class of all classes similar to a given class.) Frege
then defines zero as the number which belongs to the concept `not identical with
itself' (there being, of course, nothing which is not identical with itself).
Having defined zero, then given the notion of succession, which is definable in
logical terms, it is possible to determine all subsequent numbers." (p.290)
"The flaw that Russell
discovered in [this account] lay in the fact that it was possible to produce a
paradox over the notion of the class of all classes by asking whether the class
of classes [e.g.things] which are not members of themselves [classes] is a
member of itself or not; if it is then it is not, and if it is not then it is.
The possibility of producing that paradox seemed to cast doubt upon the very
notion of the class of all classes." (p.290)
"Frege was opposed to
what he called `psychologism'--the interpretation of logic in psychological
terms. Logic is concerned with propositions, and it is therefore important to be
clear what propositions are and what is the status of the terms that make them

(E) What in Frege is the
ambiguity of language in Russell is opacity of mind
The problem of the
paradox of awareness is expressed in Frege as indirect reference, e.g.,
Copernicus believed that the orbits of the planets were circular
For Frege numbers were
concepts, i.e., they were equla to themselves yet had a crucial property in
common
They all had in common
their extensions
The successiveness of
numbers could be established by logic starting with zero which was the only
number not equal to itself since 0 equals nothing
The mathematical history
sequence from Frege to Gödel starts with Frege's attempt to base arithmetic on
logic
For this he used set
theory, which Russell found deficient
But Russell could not
achieve what Frege attempted either
Finally, Gödel showed
that arithmetic was not explicable with logic because it was either inconsistent
or incomplete
(F) Squiggles can help
us solve the meaning/reference problem
Frege identified
knowledge with reference
He distinguished between
the sense and reference of public-language words
He had no problem with
reference, but with sense without reference
From a squiggles theory,
we can say that reference is to symbols/squiggles, which are of course the means
of expressing meaning in mind, i.e., of making sense of reality
All in mind is
reference: there is no question of sense without reference
However, when Frege said
reference he meant existents: he did not mean reference to their representation
Therefore, for Frege
knowledge meant the knowledge of existents
However, he was mistaken
because reference in mind is in part to squiggles, and the grasp of squiggles is
knowledge whether the squiggles mean a myth or an object
(G) Frege distinguished
in propositions between concept and object, between argument and function, and
between sense and reference
These distinctions have
the same purpose as my own distinction between propositional bases and
propositional content
To illustrate his point
he used the example that to say the morning star is the evening star is exactly
the same as to say that the morning star is the morning star
To understand his
problem with these propositions we have to assume Frege's perspective, which was
that we have access to thought only through words
Such being the case,
then the two expressions mean different things and contradict each other
But thought must be
logical if it is to be of any use to any one!!!
Either then thought is
different from words, which Frege would not accept, or verbal expression does
not lead to contradiction
The solution that Frege
gives to this problem is that the propositions in question have sense and
reference
Both make perfect sense
and are different but both refer to the same thing
The contradiction is in
the sense but the reference eliminates it
Likewise both have
different concepts and arguments, but both have the same function and object
The problem as I see it
is that it is possible to have the knowledge of what is not knowledge
I can believe that the
morning star is not the evening star
And this proposition
insofar as it is mine is necessarily valid
But since it has
propositional content, it can be either valid or invalid
Does this mean that I
accept Frege's thesis of the verbal extrusion of thought?
I do indeed with the
proviso that the extrusion of thought necessarily involves introspection
Since introspection is
always propositional, though, it almost comes to the same thing: Frege did not
accept propositions about mind and I do
Awareness is knowledge
is valid insofar as it refers to my belief
But it is not
necessarily valid in its contents
The sense of this
proposition is perfectly clear
But it has no reference,
in Frege's view
Nevertheless, Frege did
accept the notion of sense and sense is different from the proposition
The proposition has its
meaning from its sense
Wittgenstein put a stop
to this by claiming that the sense of a proposition is not derived from thought
but from the context of its utterance
Frege also distinguished
between direct and indirect reference
Indirect reference is
what is involved in Copernicus believed that the planetary orbits are circles
Here too he made the
sense/reference distinction, so that the sense of the proposition was true but
the indirect reference false
However, the distinction
between direct and indirect reference only makes sense if we disqualify
reference to thought itself, which is what Frege called psychologism
(H) "Frege was the
founding father of modern mathematical logic, philosophy of mathematics, and
philosophy of language. He believed that proof in mathematics should be
exhibited in a way that lays bare the deductive validity of each step, leaving
nothing to unbridled intuition. The axioms from which proof starts must be as
firm as possible--preferably truths of logic. To satisfy this procedure proofs
must be translated into a formal language with a settled vocabulary and set
modes of construction. In such a notation the construction of each sentence,
hence its meaning, and hence the question of whether it follows from previous
steps, are all explicit. Frege's greatest achievement in developing this idea
was the invention of the quantifier and variable construction to formalize
expressions of generality in natural languages" (Flew)
"Frege's first work,
Begriffschrift (Concept-Writing, 1879) was an attempt to put forward a new
notation for logic which would give it a much wider basis than Aristotelian
logic and could be used to deal with issues in the philosophy of mathematics...Die
Grundlagen der Arithmetik (The foundations of arithmetic, 1884) attempted to
show that arithmetic could be derived from the laws or axioms of a system of
formal logic; this involved the so-called logistic thesis that arithmetic, and
thereby mathematics in general, could be derived from logic.
"This programme
was carried further in his Die Grundgesetze der Arithmetik (Fundamental
laws of arithmetic, 1893-1903). Bertrand Russell attempted a similar programme
in The Principles of Mathematics (1903), and carried it through more
comprehensively and formally in Principia Mathematica (1910-13), written
together with A. N. Whitehead. In 1902, Russell wrote to Frege pointing out a
contradiction in Frege's theory...In any case, in 1931 Kurt Gödel proved that
mathematics is incomplete and that there are arithmetical truths which are
unprovable within any consistent logical system. This put an end to the logicist
programme"
"Frege holds that
numbers are objects, and the number that belongs to the concept F is, on his
definition, the extension (range of application) of the concept equal to the
concept F...Two sets or classes of objects ordered by the concepts F and G can
be said to be equinumerous if their numbers can be brought into one-one
correspondence--something that, as Frege shows, does not itself presuppose the
concept of number. Frege asks what it is to say that the number which belongs to
the concept F is the same as that which belongs to the concept G, and
answers...it is to say that the extension of the concept equal to the concept F
is the same as that equal to the concept G, that is, the classes that form their
extension have the same number of members. Analogously, Russell said that five
was the class of all quintets, and a number the class of all classes similar to
a given class...The flaw that Russell discovered in it lay in the fact that it
was possible to produce a paradox over the notion of the class of all classes ..Frege
tried to deal with the problem by restricting his theory; Russel introduced a
theory of types, which is similar to a theory of categories in forbidding us to
put things from different types on the same level." (Hamlyn)
Freedom and determinism
The concepts of deciding,
will, and so on, emerge from the implicitness of self in awareness. We have
the awareness of our specificity from which we deduce the unity of self. We
do not imagine ourselves as battlefields of forces, but do we consider
ourselves as actual unities? Do we always spontaneously imagine ourselves in
the active mood? These questions are as undecidable as freedom and
determinism.
Determinism is neither
decidable nor interesting. Birth is the big-bang of cognition. The specific
self starts from before the big-bang. For something to be specific it must
be determined by specific causes. The specific self implies determinism. If
all cognitive processes were objective, then there would be universal
agreement. Why does the absence of universal agreement preclude freedom?
This argument can only work if we assume a chain of causes and define
freedom as obedience to reason. The specificity of being means deviance from
the norm. Specificity means deviance from the logical norm and deviance from
the logical norm could mean non-determinism.
Given the subconsciousness
of cognition, is concentration or attention possible on the assumption that
it is a prolonged apparently volitional phenomenon? Each individual instant
of awareness quickly passes into memory. Since awareness is instantaneous,
then it cannot "cover" cognition in general. For reasoning and cognition to
be possible they must occur below the threshhold of awareness. If there are
instants of awareness which can be called concentration or attention, then
they too must be the result of subconscious processing. But if this is the
case how can we account for the durability and willfulness of concentration?
Volition is a propositional event in which certain propositions predominate
over other propositions. There is nothing volitional that cannot be
explained propositionally, hence subconsciously, including attention. The
durability of attention can be explained as the "sustaining" of perception
or thought from the reinforcing power of memory.
Let's say I am writing and
decide to concentrate on the view from my office window. It might have to do
with a moment of awareness, but only if we ignore that the specific self has
a continuous unbroken past. I chose to concentrate from a cognitive chain
coterminous with my experience. We never do anything on the spur of the
moment. When I say I am concentrating I am keeping before me an object of
perception or thought and I am breaking down this object into details or
parts. Since I am aware only an instant and awareness is a succession of
instants, this breaking down has to be going on in subconscious mind. And my
ability to keep this object before me and to break it down successively is
the result of the continuous interaction of basic-cogs and the cog-processes
they govern. Awareness is the illusion that what awareness does comes out of
itself and not from below its own threshhold, or from what is happening
beyond the ken of the instant of awareness. Attention is, e.g., an
interaction between the rules of perception as applied to inputs and the
rules of memory as affecting successive results of perception.
It is the subconscious which
determines awareness and not the other way around. Even when we consciously
choose to think in this or that direction, we are still under the
determination of the subconscious. But in all cases there is no argument for
determinism that can make us disbelieve in our ability to be free. The will
of the specific self sees itself as the denial of determinism, whatever
arguments we can muster for determinism. Talk of determinism always tends to
trail off into free-will talk. Free will is embedded in language. Yet the
very strong arguments for determinism--and the crucial one we haven't used,
which is the absence of a hiatus in being--mean that compatibilism is about
the only reasonable position there can exist between determinism and free
will.
Success and failure have
nothing to do with freedom or determinism. It is not freedom which gives us
success. We are not determined towards defeat. There are rules and
mechanisms in the world, and there are personal traits and attitudes, not
excluding specific volition, that will determine whether we succeed or fail.
If the world and history are rational and "look" towards rational goals,
then if what we are doing is of value to the achievement of rational goals,
we should succeed, and if what we are doing is not of value to rational
goals, we will not succeed. This is about as close to determinism as we can
get, and even this is unacceptable to the specific self, who refuses point
blank to accept the thesis of determinism.
Behaviour is determined
internally and externally but it is not possible to make a sharp distinction
between forces because they are usually mixed and interactive. On the
external side, two basic "axioms" are fear and imitation. Fear is coercive
and imitation "voluntary". Basically, we are either forced or enticed from
the outside. But external forces do not explain everything. There are also
the "internal" traits proper to the specific self. There is no way that
coercion or imitation can be explained without the specific self as the
basis of all "axioms" of behaviour.
From the perspective of
cognitive processes it is qualitatively impossible to distinguish between
axioms of behaviour. And if axioms of behaviour are the same at the source,
then our behaviour is more the result of our specific selves than of fear of
others or the wish to imitate them. If fear, imitation, and the specific
self are names for special cognitive processes, then all behaviour, being
the result of cognition, necessarily partakes of these special cognitive
processes, e.g., all apparently imitative or all apparently fearful
behaviour is also self-specific and of course all self-specific behaviour
also has imitative and coercive components. There is no point in making such
distinctions. Their usefulness is another matter, but usually over time what
is groundless tends to be useless.
All behaviour is anteceded
by propositions. The propositions/behaviour relation is unbreakable. We
assume that knowing the propositions should allow us to predict the
behaviour. Whatever principles determine the propositions are the principles
of behaviour. All we can do in the matter of predictive laws is to set up a
cognitive model and try to discover behavioural "trends" on the basis of
specificities. Since specificities are proper to individuals, there is no
question of trends in general: only of trends in individuals. To try to be
precise about the prediction of behaviour we would have to have, apart from
the cognitive models and its principles--for which we cannot claim more than
interpretation--constant complete knowledge of all specificities of the
individual mind. Such knowledge--just to give the magnitude of the
problem--would have to consist in ultra-precise quantifications of pain and
pleasure, of logic and memory, and so on. Cognition would have to be
infinitely subdivided and each fragment of each subdivision would have to be
minutely analyzed. Even animals, from this standpoint, with vastly simpler
cognitive organizations, are only marginally, precariously predictable.
The last complication is
that, after all has been calculated to the most infinitesimal detail, then
we have to assume that nothing unforeseen will come from the world and upset
the balances we so carefully set up. In the case of, say, a gazelle being
hunted by a predator, a minimal change in the atmosphere could give the prey
a sudden but decisive olfactory warning. The predictive process would also
have to depend on the exact knowledge of the way the world is configured at
any particular moment. In sum, neither "laws" nor predictions are possible
in respect to thought and behaviour. But when all is said and done to
discard the possibility of laws because they can never be uncovered and
formulated, is not a necessary deduction. The "laws" must exist only we
cannot get at them, and even though we have precluded accessibility, we
really have no basis for denying that somehow in due time these "laws" will
be functionally known, i.e., known sufficiently for certain practical
purposes if not for the constant prediction of action.
Reason and will
Kant argued for reason and
will. There are arguments for an object-self and objective cognition in
relation to volition in Kant's writings on ethics. In Kant, deciding runs
the gamut from, in effect, taking one's life to choosing how to kill the
next five minutes. The process is of course psychological, but not
discretely so. Into deciding enter perception, rationality, affects,
currently known particulars and "things" below the threshold of
consciousness, the past and expectations, and so on. They do not enter in
ordered ranks, nor do they exit after examination permanently. They enter
higgedly-piggedly and they come and go continually, often without our being
aware of it. This is true of what to do next. But it is no less true of
suicide, for suicide is a process and even if the final decision might
conceivably be ghastly cold--for which there is some evidence--in the
process the previous "disorderliness" must have been there most of the time.
Admittedly "disorderliness" might be a matter of perspective, but it is a
valid qualification as long as we do not have unimpeachable grounds for
arguing that everything has a purely rational cause.
But surely, even if there
were an universal order, this order could encompass some "chaos" without
losing its "composure"? There may be instances of deciding from a purely
rational stance. But there are other things to be observed here: one, even
as we are deciding we are deciding. This is not wordplay: a decision is a
temporal process and reason is biconditional with memory. Even if we could
actually "lean" the process to the starkest essentials, it still requires
memory and choosing between evidences and moments, and these are not subject
to precise rational decisions. In the end, we may indeed have decided on a
rational course for rational considerations, but this process is never
accomplished without the admixture of unreason or at least of circumstances
which cannot be rationally accounted for. Two, the final decision could be
not to do something or to let something pass. It could be in brief a passive
stance, and this can mean not choosing to recall or to move and say things,
but simply allowing thought to take its own course, in other words, "doing
nothing". Doing rationally, then, can be doing nothing. It is not possible
to find "will" in all the above. But what we do find is the hodgepodge of
the stream of thought, which may be rational, very likely is rational in the
sense of the universe being rational, but which we could no more prove to be
rational than we can say at precisely what moment and for precisely what
reasons I decided to fulfill a moral law.
Action is always contextual
and it is impossible not to consider its consequences. Duty, morality, so
on, are defined and understood in terms and only in terms of obedience to a
principle. Everything else--purpose, effects, goals, so on--is to be
disregarded, for nothing else has to do with morality. Yet laws have
purposes, so to obey the law must be in pursuance of a purpose. To this Kant
can allege his distinction between laws and the principle or reason behind
the laws. But this is as spurious as the attempt to obliterate all thought
of consequences from ethics.
The categorical imperative
has only limited applicability. "When I conceive of a hypothetical
imperative at all, I do not know previously what it will contain until I am
given the condition. But when I conceive a categorical imperative I know at
once what it contains." This implies that the categorical imperative is not
always relevant or applicable, but how can we be faithful to reason and
morality and go around making all sorts of practical compromises? And
additionally if the categorical imperative is only justified in certain
situations, before we apply it or even think of it, we have to work our way
from experience to pure reason, and Kant has expressly stated that the
categorical imperative is a prioristic.
"Morality is then the
relation of actions to the autonomy of the will, that is, to the possible
general laws made by its maxims. An action that is consistent with the
autonomy of the will is permissible, one that is not congruous with it is
forbidden." This implies that good actions are not those which are not
forbidden: all good actions must have some positive intent related to
autonomy of will. There is a complex argument against this implication.
Since it is not possible for the will to be always autonomous--sometimes we
have to keep an eye on results--there is implicit here a whole range of
behavior which is neither good nor bad, and as good is permissible and bad
forbidden, but actions which are neither good nor bad are permissible, then
there are good actions which are not necessarily the result of the autonomy
of the will.
Kant considers some duties
to see whether they can be derived from the categorical imperative and the
first one he turns to is not taking one's life. But in fact he had already
done this in the commonsensical part of his treatise where he defined the
moral worth of a deed as consisting in its accomplishment despite adversity.
Let us assume that this time he puts this duty on a more solid base by
relating it to the categorical imperative. It rather seems not that the
categorical imperative is justifying duties but that priorly known duties
are justifying the categorical imperative. Whichever way, he had formulated
the categorical imperative (or something very much like it) in the first
part. We have advanced not one whit. And there's the objection that the
example he uses of not taking one's own life as a manifestation of the
practical application of the categorical imperative is really quite
problematical.
To go on living requires
nothing. It can be multiply motivated. In fact, it does not even require a
maxim or a motivation. To find some sort of moral meaning in not taking
one's life would require, first, that one considered the possibility of
taking one's life; then, that one actually contemplated taking one's life;
and thirdly, that one then decided not to take one's life. But is this a
moral decision stemming from the categorical imperative? All the duties he
mentioned depend for their justification on their consequences. The only
real reason we cannot accept suicide as a morally permissible action is not
that I cannot wish my suicide to be universal law but that if we condoned
suicide we could be at the same time condoning a threat to the fabric of
society.
Robert Kane on Martha Klein,
Determinism, Blameworthiness and Deprivation (Oxford: Clarendon
Press), in TLS, August 31-September 6 1990, p. 927
"Her discussion of moral
responsibility-entailing choice (`free-will' in Leibniz's traditional
language) centres on what she calls the `U-(or ultimacy) condition for
blameworthiness': `an agent's morally reprehensible decisions or choices
should not be caused by factors for which he is not responsible'. If your
present choice issues from past character and motives, then to be morally
responsible for the choice you must be responsible for the character and
motives issuing in it. This suggests a familiar regress. Must you not also
be responsible for the earlier character and motives? To escape, one must
assume the existence of originating, buck-stopping, choices that are
`uncaused' or `undetermined' by factors that went before them."
"Emphasizing the U-condition goes against
the grain of much recent debate about determinism and blameworthiness, which
has focused on what Klein calls the `C-condition'--that free agents `could
have done otherwise'. She correctly argues that the C-condition is not
necessary for blameworthy action, and is even tempted to dismiss it
altogether as irrelevant for moral responsibility."
"Klein argues that only `reasonless' (or
motiveless) choices could satisfy the U-condition and that these are
empirically impossible. But reasonless choices are not the only things that
will satisfy the U-condition. There is a way to make sense of originating,
undetermined choices which satisfy the conditions of `ultimacy' and
`could-have-done-otherwise,' as well as `intentionality' and `rationality'
(they are not reasonless)...Free agents can have ultimate, but not absolute
(that is, complete) control over the outcome of originating free choices.
Hence responsibility and blameworthiness for them is never complete (and
`moral luck' is more deeply involved in the human condition than we
thought). This is a concession eminently worth arguing about. So the debate
will go on--but the focus will have shifted away from the idea that
incompatibilist views cannot be given any coherent formulation."
Robert Kane on Linda Trinkaus Zagzebski,
The Dilemma Of Freedom And Foreknowledge (Oxford) and on Susan Wolf,
Freedom Within Reason (Oxford) in TLS August 30 1991
"The main difficulty for traditionalists
like Zagzebski is that they will not allow as a solution to the problem any
view which limits divine foreknowledge. By contrast recent writers like
Richard Swinburne and William Hasker are ready to bite the bullet and
acknowledge that God does not have foreknowledge of all future free action."
It could be argued that he can
"calculate" the future perfectly without actually having foreknowledge, but
this still places God in time and this is scary. We do not have answers. We
can only suppose this or that.
"Wolf...sides with those who dismiss the
libertarian view of free will as unintelligible; I think they dismiss it too
hastily. The recent renaissance of interest in the subject has given us a
better understanding of the libertarian view. The responsibility associated
with such a view was traditionally thought to require two conditions.
Ultimacy, or the U-condition, as Martha Klein has called it (`to be
responsible for our actions we must be responsible for the character and
motives that produced them'); and explicable (`responsible actions must be
in terms of the character and reasons of the agent which precede them'). It
turns out that these conditions cannot be simultaneously satisfied. If
libertarian free will requires both, it is an incoherent ideal...Compatibilists
react by rejecting the Ultimacy condition, which they think is the source of
the incoherence because it requires indeterminism and leads to regresses and
other paradoxes."
Freud
(A) Freud specified
and formalized neurosis
He sought rational
explanations for neurosis
He applied reason in
situations so peculiar that they did not seem rational
Envy is a rational
sentiment, e.g., a footsore hitchhiker who sees someone else get a ride
But is penis-envy
rational?
Fear of castration is
rational where the threat even just might conceivably exist, e.g., certain
stunts
But is fear of
castration in a child rational?
The application of
reason to Freudian situations is to say the least strained
Therefore, we can say
that, even though Freud did specify and formalize neurosis, some of his
inferences from them were certainly far-fetched
Among those inferences
were that neurosis are rational and that they can be cured through memory
exercises in couch-analysis
Neurosis is more
resistant to talk than he thought

The tripartite theory
"Freud regarded
psychosis as the result of conflict between ego and reality and viewed neurosis
as an intra-psychic conflict among the id, ego, and superego."
Freud was first and
foremost a clinician and from this activity emerged his ideas on psychology
It cannot be asserted,
however, that he broke root and branch with traditional psychology
The definition of the
ego was a life-long concern with him
It went through several
phases
"the first phase, ending
in 1897, saw the ego as a dominant mass of conscious ideas and values distinct
from the impulses and wishes of the repressed unconscious" (122)

"Anxious expectation is
the nuclear symptom of [anxiety neurosis]. It openly reveals, too, a portion of
the theory of neurosis. We may perhaps say that here a quantum of anxiety in a
freely floating state is present, which, where there is expectation, controls
the choice of ideas and is always ready to link itself with any mutable
ideational content".

[conditioned awareness]
Meissner
"The second phase of the
concept of ego, from 1897 to 1923, was influenced by Freud's abandonment of the
seduction hypothesis and his concern with the instinctual drives, their
representations, and their transformations. The concept of ego was closely
linked to the ego instinct, which Freud was struggling to clarify. Defense was
limited primarily to repression and consisted of an instinctual force directed
against unconscious derivatives. The ego's activities followed the reality
principle and secondary process and included the capacity for delay of
gratification.
The Interpretation of
Dreams (II) (1900)
"It is instructive to
consider...the significance of a hysterical phobia or an agoraphobia. Let us
suppose that a neurotic patient is unable to cross the street alone--a condition
which we rightly regard as a `symptom'. If we remove this symptom by compelling
him to carry out the act of which he believes himself incapable, the consequence
will be an attack of anxiety; and indeed the occurrence of an anxiety-attack in
the street is often the precipitating cause of an onset of an agoraphobia. We
see, therefore, that the symptom has been constructed in order to avoid an
outbreak of anxiety; the phobia is erected like a frontier fortification against
the anxiety"--p.581

produces anxiety]

What Freud Really Said, Schocken Books, N.Y., 1966, 1976
"The Three Essays
(1901-1905) will always remain one of Freud's major works. They provide the
foundation for his theory of neuroses, the explanation of the need for
repression and the source of emotional energy underlying conscious and
unconscious drives and behaviour which he names libido"--p.105
"This concept of the
available quantity of original sexual energy (libido) being limited, and of its
compulsive fixation at various levels of development short of maturity in some
individuals, was to provide Freud with the basis of his general theory of
neuroses"--p.115
"It was possible in
Freud's day, and it is possible now, to take simple clinical examples for the
main forms of neuroses. We can list them and then consider them briefly one by
one:
(1) hysterical illnesses
and hysterical personality
(2) states of anxiety
and anxious and vulnerable personalities
(3) obsessive compulsive
disorders and obsessional personalities
(4) neurotic depression
and personalities specifically vulnerable to defeat and despair of this kind
(5) hypersensitive,
suspicious and paranoid attitudes, and the personalities prone to them
(6) specific disorders
of sexual immaturity, and personalities involved in and damaged by
this"--pp.142-3
"Freud classified the
neuroses in terms of their aetiology...His classification divided them into
actual neuroses and psychoneuroses. Actual neuroses were disturbances of
subjective well-being and physiological balance, entirely consequent upon a
frustration of libidinal fulfilment or exhaustion of libidinal energy...For
neither of these conditions did Freud consider psychoanalysis appropriate.
"[The
psychoneuroses] were patterns of neurotic activity entirely determined by
unconscious mechanisms, in response to the various hazards to which the
unconscious drive towards unconditional libidinal satisfaction must inevitably
expose the developing human being. Freud divided the psychoneuroses again into
two groups, the transference neuroses and the narcissistic neuroses...Anxiety
neuroses, anxiety hysteria, hysterical conversion neuroses and obsessive
compulsive neuroses were transference neuroses. Severe neurotic depression,
paranoid states and those borderline states of disturbance which lay between
personality disorders and schizophrenia were narcissistic neuroses"--p.150-2
"Underlying [neuroses],
Freud saw as decisive the Oedipus complex--the threat to the infant of its
inevitable desire for possession of the mother, with the inescapably concomitant
risk of talion punishment from the father"--p.152

of, and what consequences he fears, should it emerge into conscious discharge
and expression.
"What he fears is
the escape from the prison of the unconscious of aggressive and libidinal crises
and their derivative emotions and fantasies" p.176
Introductory Lectures
(1915-17): "Obsessional neurosis is shown in the patient's being occupied with
thoughts in which he is in fact not interested, in his being aware of impulses
in himself which appear very strange to him and in his being led to actions the
performance of which give him no enjoyment, but which it is quite impossible for
him to omit. The thoughts (obsessions) may be senseless, or merely a matter of
indifference to the subject; often they are completely silly, and invariably
they are the starting-point of a strenuous mental activity, which exhausts the
patient and to which he only surrenders himself most unwillingly. He is obliged
against his will to brood and speculate as though it were a question of his most
important vital problem...What is carried into action in an obsessional neurosis
is sustained by an energy to which we probably know nothing comparable in normal
mental life"--pp.155-6
"Freud saw obsessional
neuroses as essentially a regression of the libido to the earlier infantile
state of sadistic-anal organization; a stage in which the infant could not
directly experience, even in imagination, the possibility of a love for the
parents free from aggressive, destructive and defiant impulses. This aggression
transforms normal relationships into deeply unconscious infantile ones. For the
idea `I would like to love you, and to enjoy you in love', there exists in the
repressed form only the idea `I should like to be strong enough to kill you'.
This latter idea contains the phantasies of omnipotence which are the infant's
compensation for his developing awareness of his helplessness in relation to
those whom he wants to love"--pp.156-7
"...it is easier to see
now what Freud was never fully to express or finally to acknowledge: namely,
that what he called the narcissistic neuroses are probably not primarily
psychogenic in origin"--p.162
"Transference neuroses
correspond to the conflict between the ego and the id; the libidinal drive
reaching the ego from the id has been frustrated, distorted, subject to
inhibition or aggression, or fixated at a level short of fulfilment, because the
circumstances of the ego could not competely express or tolerate it. Then
narcissistic neuroses remained those in which the withdrawal of libidinal
attachments or cathexis to the outside world left an overwhelming reinvestment
of emotion and concern attached to the ego itself"--pp.163-4
"A man might become
jealous of his wife because his repressed homosexual impulses compelled him to
deny that he did not want her, and forced him to substitute the displaced
projection that she did not want him and was therefore being unfaithful to
him"--pp.166-7
Obsessive behaviour in
the rat-man: "For example, on one occasion the woman he loved was due to leave a
certain town, and he was walking along the route her carriage would take on the
way to the station when he saw a stone on the road. He immediately felt
compelled to remove it in case the carriage wheel should run over it and the
carriage then overturn and harm her. As soon as he had removed it he was not
sure whether he had not put it in a more dangerous position, or that its removal
might not cause some other catastrophe. He therefore felt compelled to replace
it"--p.178
Meissner
"During the third phase,
from 1923 to 1937, the structural theory emerged in which the ego was defined as
a structural entity and was definitely separated from the instinctual drives.
Within the structural framework, the ego was a coherent organization of mental
processes and functions oriented toward the perceptual-conscious system, and it
included mechanisms responsible for resistance and unconscious defense"
S. Freud, The Ego and
the Id (1923), chapter V: "The Dependent Relationships of the Ego", in
volume 19, pp.48-59
"There are certain
people who behave in a quite peculiar fashion during the work of analysis. When
one speaks hopefully to them or expresses satisfaction with the progress of the
treatment, they show signs of discontent and their condition invariably becomes
worse"--p.49
"In the end we come to
see that we are dealing with what may be called a `moral' factor', a sense of
guilt, which is finding its satisfaction in the illness and refuses to give up
the punishment of suffering"--p.49
"An interpretation of
the normal, conscious sense of guilt (conscience) presents no difficulties; it
is based on the tension between the ego and the ego ideal and is the expression
of a condemnation of the ego by its critical agency"--p.50-1
[awareness conditioning]
"What is now holding
sway in the super-ego is, as it were, a pure culture of the death instinct, and
in fact it often enough succeeds in driving the ego into death, if the latter
does not fend off its tyrant in time by the change round into mania"--p.53
"The super-ego arises,
as we know, from an identification with the father taken as a model"--p.54
"[In obsessional
neurosis] The defusion of love into aggressiveness has not been effected by the
work of the ego, but is the result of a regression which has come about in the
id. But this process has extended beyond the id to the super-ego, which now
increases its severity towards the innocent ego"--p.55
The Ego: "By virtue of
its relation to the perceptual system it gives mental processes an order in time
and submits them to `reality-testing'. By interposing the process of thinking,
it secures a postponement of motor discharges and controls the access to
motility...All the experiences of life that originate from without enrich the
ego; the id, however, is its second external world, which it strives to bring
into subjection to itself. It withdraws libido from the id and transforms the
object-cathexes of the id into ego-structures"--p.55
"What it is that the ego
fears from the external and from the libidinal danger cannot be specified; we
know that the fear is of being overwhelmed or annihilated, but it cannot be
grasped analytically"--p.57
"It seems to
me...perfectly correct to distinguish the fear of death from the dread of an
object (realistic anxiety) and from neurotic libidinal anxiety"--p.57-8
"The fear of death in
melancholia only admits of one explanation: that the ego gives itself up because
it feels itself hated and persecuted by the super-ego, instead of loved. To the
ego, therefore, living means the same as being loved--being loved by the
super-ego, which here again appears as the representative of the id. The
super-ego fulfills the same function of protecting and saving that was fulfilled
in earlier days by the father and later by Providence or Destiny"--p.58
"These considerations
make it possible to regard the fear of death, like the fear of conscience, as a
development of the fear of castration"--p.58
Meissner
"The fourth phase of ego
concept began with Anna Freud's The Ego and the Mechanisms of Defense
(1936) and culminated in the systematizing elaborations of Heinz Hartmann and
David Rapaport. Hartmann's key contributions were the development of a theory of
ego autonomy and emphasis on the principle of adaptation. Ego autonomy refers to
the innate or acquired capacity of the ego to function independently of
instinctual impulses and the influence of drive derivatives. Adaptation refers
to the capacity of the organism to fit in and adjust harmoniously to the
environment. The adaptational approach not only linked psychoanalytic theory
with biological thinking but also laid the groundwork for elaboration of
analytic principles into the framework for a general psychology of behavior"

Carl Rogers (1902- )
"Within Roger's
phenomenological and organismic theory, the phenomenological field is equivalent

evaluation of himself" (138)
The fundamental demarche
in the discovery of neurosis was the abandonment of the mind/body pathological
link: neither were physical or physiological lesions or malfunctions the cause
of abnormal conduct, nor was deviant behaviour necessarily a manifestation of
actual organic disorders. In explaining this "halfway house" between madness and
"normalcy", Freud speculated along various convergent paths: childhood
impressions, the subconscious, and instincts, especially the libido, and their
disruptions.
He further extended the
disassociation between objectivity and subjectivity implicit in the separation
between mental states and actual physical causes, by substituting imagined
traumas for actual traumatic events in the etiology of the neurotic condition.
This placed psychological "research" squarely within the area of introspection.
However, the elevation of introspection to a privileged methodological status,
also conjured up the spectre of subjectivity. Rational categories were necessary
to carry on beyond introspection, but this could not obviate the ultimate
reliance on the data of individual experience.
Freud conceived a rigid
scenario or schema for reducing neurosis to rationally manageable patterns of
thought and action, which presupposed the functional existence of the
subconscious beyond such self-evident operations as memory and reason. The
OEdipal complex, as he called it, postulated interferences in early childhood
that dislocated or displaced the normal channeling of affective and in general
psychological energies resulting in, among other things, emotional immaturity,
obsessive thought and behaviour, specifically symbolic dreaming, and even
parapraxes.
Neurosis was diagnosed
as the involuntary inability of an individual to work out or to surmount the
OEdipal scenario. The capping of the psychoanalytic programme was the notion of
the evacuation of the neurotic syndrome through therapeutic couch-analysis,
which consisted in memory exercises for the patient with the assistance of the
psychoanalytic clinician.
In the psychoanalytic
scheme, the castration trauma--and other similar traumas--has its effect on the
situation described in the so-called topographic model of the instinctual
economy of the mind
The concept of
topography originates in that the traditional qualitative
distinctions--intellect, volition, affectivity, "instinctuality"--are
disregarded in favour of a terrain image or perspective
The instinctual economy
refers to the idea that mental energy is limited--like resources in an
economy--and must be shared out between different instinctual claims
The war of the instincts
for predominance can lead to manifestations such as anxiety or shaking
More concretely, the
repression of sex produces generalized guilt feelings and guilt in turn leads to
timidity, insecurity, and so on
The effects of traumas
are eventually translated into neurotic symptons such as emotional immaturity,
mother fixation, impotence, homosexuality, etc.
I presume there are
proto-symptons
How and why are proto-symptons
transformed into symptons?
From the evolution of
the individual and the change in his societal circumstances
All of this amounted to
making two monumentally controversial statements: (1) on the therapeutically
reducible nature of what is in effect an existential problem, and (2) on the
possibility of self-knowledge from the assumption that "cure"lies in the
enlightenment achieved by the patient himself.
"Cure" applied to the
individual neurotic condition and did not affect the burdensome awareness of the
general constraints on existence.
The summatory
psychoanalytic statement on neurosis was contained in the OEdipal scenario,
whose dénouement appeared to derive from the Socratic dictum: "Know thyself",
but only in connection with the OEdipal scenario.
In sum, the basic
failure of psychoanalysis is that to work its explanations must be internalized
as belief in the individual and the scenario it constructs to explain neurosis,
i.e., the OEdipus thingamajig, is simply not believable, except perhaps in the
very rare cases where it happens to have taken place, or at the very least,
something like it
The greatest flaw in the
psychoanalytic agenda is that in its commitment to the alleviation of malaise,
it faces the problem that mind can derive relief for itself from itself alone.
It does not matter where that relief originates as long as mind "naturalizes" it
within itself. It is not only that it is only neurosis that can know itself; it
must also explain itself from itself alone. Mind in brief will not give its
assent about itself to anything but its own specific cognition. No general
abstract formulation will satisfy self-awareness and no external source can
speak for awareness, and the OEdipal construct, with its assertion of
undemonstrated, and undemonstrable, psychical energies and instinctual drives,
rather than answering the appeal of self-awareness for enlightenment, seems
instead to demand that mind mould itself to its own postulates.
It is possible to raise
strong objections to the theoretical structure within which neurosis was
originally typified. The psychoanalytic programme is built on a double helix of
related perceptions: neurosis immediately as its own verbalization and the
external rational interpretation of the self-perception of neurosis. On close
rational scrutiny, the specific psychoanalytic perception loses force. The
patterning function of the OEdipal scenario presupposes the repetition of
events, e.g. the perceived threat of castration, that are accidental rather than
invariant.
Fear and envy of the
father-figure do not necessarily require an OEdipal attachment to the mother;
they can arise from only the father/child side of the familial triangle leading
to the same social symptons as are attributable to an unresolved OEdipus
complex. In certain instances, so-called OEdipal manifestations, e.g. emotional
immaturity, can co-exist with traits, e.g. rejection of the mother, at odds with
OEdipal behaviour expectations.
Even in the crudest
state of non-resolution, the OEdipus scenario should cease operating at some
point in time, yet further neurotic manifestations are made dependent on its
residual subconscious effects when in fact the self/environment inter-action
throughout life would seem to be more influential on thought than any other set
of circumstances.
To the disruptive
libidinal fixations proposed by psychoanalysis can be opposed the notion of a
process of sexuality through development, conditioning, or some other mechanism.
In fact, the deviation
of the libido in any direction can be explained from the Freudian principle of
the conservation of psychological energy without the benefit of the OEdipal
construct.
Functionalism
An overview of functionalism is that it assumes that mental states are a form of behavior (computers are observable) and since behavior is caused mental states are caused. The functionalist separation between software and hardware is not easy to maintain in parallel to mind and brain. A hardware failure need not portend a software failure, although of course it could portend a software malfunction. To get over a hardware failure all you do is take the software and put it in another machine. It is difficult to assume that brain damage will not affect thought. And under the theoretical assumptions of functionalism the hardware cannot be identical to the software, for functionalism is the belief precisely that thought is autonomous and can be instantiated in substances other than brains. Given these difficulties with the analogy at the heart of functionalism, it would seem more productive to assume physicalism in the forefront and to keep functionalism in the background. In analogous monism I borrow symbolism for mind--although it can easily as well be derived from the temporality of thought--and shape to it to fit a neurological model.
Functionalism poses as many difficulties as metaphysics and folk psychology, as can be seen in Papineau's teleology, or in Dennett's intentionalism. Event-identity physicalism is at best a problematical theory. It is impossible to demonstrate either determinism or indeterminism. Circularity, which seems useless, is at the heart of rationality.
David Papineau on Daniel C. Dennett, The Intentional Stance (MIT Press), in TLS, August 19-25 1988, P. 911
"The materialistic shift in recent analytic philosophy represents a remarkable turnaround. In the 1950s and 60s philosophers used to divide on whether `reasons' were `causes', with neo-positivists like A. J. Ayer maintaining that mental states caused behaviour according to general scientific laws, while hermeneuticians like Peter Winch insisted instead that the attribution of mental reasons yielded a distinctive, non-causal way of understanding human action. Strikingly absent from that agenda, however, was the question of how the mind related to the brain. Even the positivists tended to deal with the mind in its own terms, relating beliefs and desires to actions directly, without bringing in the brain as the locus of mental states."
"Now that physical discourse has its own authority, the only way to relate mind to matter is somehow to find space for the mental within the physical."
"Dennett's position on the mind-brain issue combines elements of both orthodox `functionalism' and Donald Davidson's `anomalous monism'. Functionalism is the modern physicalist version of Ayer's positivism. Like Ayer, functionalists take everyday psychology to specify general causal relations between mental states and behaviour, but then add the physicalist twist of identifying those mental states with the brain states that play the same causal roles in our physical workings. Davidson, by contrast, is the physicalist heir of Winch. While accepting the general monist principle that everything, including humans, is made of matter, Davidson resists the further inference that psychology should dance to the same scientific tune as physics. He maintains instead that psychological terminology is `anomalous', in being unsuitable for the formulation of general scientific laws, and insists, with Winch, that the point of our everyday psychological notions of belief, memory, desire, intention and so on, is to enable us to make hermeneutic sense of people's actions, not to categorize them scientifically."
"One of the issues involved here is the debate between `connectionists' and `linguistic' models in artificial intelligence. In the 1970s the fashionable theories of the mind postulated `languages of thought', consisting of sentence-like structures which the brain possessed in sequence like a conventional computer. But it has since become clear that this is too cumbersome for abilities involving pattern recognition, and the fashion is now for `connectionist' models, in which mental judgements are embodied in holistic networks of simple non-sentential elements. Dennett argues, not unreasonably, that this shift in fashion casts little doubt on folk psychology, on the ground that there was little in folk psychology to commit us to the language-of-thought picture in the first place. But this scarcely establishes Dennett's more general thesis, that folk psychology carries no implications whatsoever about internal mechanisms."
Functional-role semantics
Approximately, functional-role semantics is the theory that meaning is subject to the laws of inference, i.e., that thought is logical, and that logic is causal.
