Actual Consciousness
A Lecture
17 April 20141 Need for adequate Initial Clarification of Consciousness?
You are conscious just in seeing this room you are in,
conscious in an ordinary sense of being aware of it. That is not to say what is
different and more, that you are seeing or perceiving the room, with all that
can be taken to involve, including stuff about your visual cortex and maybe
retinas. To say you are conscious just in seeing this room is not itself to
say, either, what is often true, that you are attending to the room, fixing
your attention on it or on something in it.
You are now conscious, secondly, I am sure, in having certain
thoughts, no doubt about what you are hearing.
You
are conscious, thirdly, in having certain feelings, maybe the hope that
everything is going to be clear as a bell, maybe in intending to leave early if
it isn't.
What are those three states, events, facts or things? What is
their nature? What is the best analysis or theory of them? What is what we can
call perceptual consciousness, cognitive consciousness, and affective
consciousness? There is also another question, as pressing. What is common to
the three states, events or whatever? What is consciousness in general? What is
the kind of state, event or whatever of which perceptual, cognitive, and
affective consciousness are parts, sides, or groups of elements? As I shall be
remarking later in glancing at existing theories of consciousness, the known
main ones answer only the general question. Is that a good idea? Is it a
possible idea if you want the philosophy of mind to be better? We can ask the particular questions and the general question in
mainstream philosophy. It is a greater concentration than that of science on
the logic of ordinary intelligence: (i) clarity, usually analysis, (ii)
consistency and validity, (iii) completeness, (iv) generality – generalness. Is
it safe enough to say that philosophy is thinking about facts as distinct from
getting them?
Another preliminary. There are ordinary and there are other
related concepts of things, ordinary and other senses of words -- say
stipulated or technical ones. Let us ask what it is to be conscious in the primary ordinary sense, in the core meaning of the word -- and what it
is to be conscious in each of the three ways in the primary ordinary sense. Do
you ask if that is the right question? Assume it is and wait for an answer in
the end.
We have what Searle rightly calls a common sense definition,
something he calls unanalytic, of what seems to be this ordinary consciousness
-- presumably must be ordinary since it is common sense. This consciousness in
the definition is states of awareness
that we are in except in dreamless sleep. That has the virtue of including
dreaming in consciousness, which surprisingly is not a virtue of all
definitions, notably a slightly mad Wittgensteinian one. But how much more
virtue does the common sense definition have? Awareness obviously needs defining as much as consciousness.
Each of us also has something better than a common sense
definition, a hold on her or his
individual consciousness. That is, each of us can recall now the nature of
something a moment ago, consciousness of the room, or a thought, or a feeling.
I guess that is what has been called introspection, and doubted because it was
taken as a kind of funny inner seeing, and people or subjects in psychology
laboratories were asked to do more with it than they could. Forget all that. We
can be confident right now that each of us can recall that thing of consciousness
a moment ago.
There are lesser and greater pessimisms about our answering
the general question of consciousness. Greater pessimists have included Noam
Chomsky, Tom Nagel, David Chalmers -- and Colin McGinn, who began by saying we
have no more chance of getting straight about consciousness than chimps have of
doing physics.
Here is a first question for you, a first piece of this
lecture. Are those pessimisms and also, more importantly, the great seeming
disagreement about what consciousness is, owed at least significantly to one
fact? The fact that there has not been agreement on what is being talked about,
no adequate initial clarification of the subject matter, people talking past
one another? In a sense, of course, that is not disagreement at all, but a kind
of confusion.
2 Five Leading Ideas of Consciousness I'd say there are five leading ideas of consciousness. They
are about qualia, something it's like to be a thing, subjectivity,
intentionality, and phenomenality. Fly through them with me, in fact over them.
Qualia Dan Dennett says qualia are the ways things seem to us, the
particular personal, subjective qualities of experience at the moment. Tom
Nagel says qualia are features of mental states. Very unlike Dennett, he says
it seems impossible to analyse them in objective physical terms, make sense of
them as objectively physical. Ned Block has it that they include not only
experiential properties of sensations, feelings, perceptions, wants, and
emotions. They are also such properties of thoughts,
anyway our thoughts that are different from the sort of thing taken to be the
functioning of unconscious computers -- computation or bare computation.
Do we get an adequate initial clarification of the subject of
consciousness here? No. (i) There is only what you can call a conflicted
consensus about what these things are to be taken to be. (ii) In this consensus
one thing that is very widely assumed or agreed. Qualia are qualities of consciousness, not what has
the qualities, consciousness itself, maybe its basic or a more basic quality.
(iii) Another thing agreed is itself fatal to the idea of an adequate initial
clarification -- that qualia are only part of consciousness. There's the other
part, which is what are called propositional attitudes.
Something it's like to
be a thing That idea of Nagel in
his paper 'What It's Like To Be a Bat', however stimulating an idea, as indeed
it has been, is evidently circular.
Searle in effect points to the fact when he says we are to understand the words
in such a way that there is nothing it is like to be a shingle on a roof. What
we are being told, it seems to me, is that what it is for something to be
conscious is for there is something it is like for that thing to be conscious. Also, you can worry, no
reality is assigned to consciousness here. Can there be reality without a positive
assurance of physicality?
Traditional
or familiar subjectivity Here, whatever
better might be done about subjectivity, there is circularity. Consciousness is
what is of a subject, which thing is
a bearer or possessor of consciousness. There is also obscurity. Further, a
subject of this kind is a metaphysical self. Hume famously saw off such a
thing, didn't he, when he reported that he peered into himself and could not
espy it?
Intentionality The
idea was brought into circulation by the German psychologist Brentano in the
19th Century and has as its contemporary defender and developer Tim Crane. It
is usually and better spoken of as aboutness,
where that is explained somehow as also the puzzling character of spoken words
and seen images. There is the great problem that when intentionality is made
clear by way of likeness to words and images, it is evident that it is only
part of consciousness. As is often remarked, it leaves out aches and objectless
depression. Crane says otherwise, to me unpersuasively.
Phenomenality
Block speaks of the concept of consciousness as being hybrid or mongrel, and
leaves it open whether he himself is speaking of consciousness partly in an
ordinary sense. He does concern himself, certainly, with what he calls phenomenal consciousness, as does
David Chalmers. This is said by Block, not wonderfully usefully, to be 'just
experience', just 'awareness'. I add in passing that he takes there to be
another kind of consciousness, access
consciousness, which most of the rest of us recognise as what we call
unconscious mentality, say brain-workings. Here, I remark in passing, is a
first and striking instance of philosophers or scientists definitely not meaning
the same thing as other philosophers or scientists. How many more instances do
we need?
A
last remark about the five ideas. It is notable that
Chalmers takes them to come to the much the same thing, one thing, to
pick out
approximately the same class of phenomena. He is not alone in that
inclination.
But evidently the five things are different. Those five lots of
thinkers are indeed talking about differentthings, as indeed they say.
And can their various disabilities conceivably add up to something
clear and useful?
3 Something's Being Actual Is confession good for a philosopher's soul? Well, some from me might
help out with your getting an early hold on a lecture. I sat at a table some
years ago and said to myself stop reading all that madly conflicting stuff
about consciousness. You're
conscious. This isn't Quantum Theory or its worldly interpretation, let alone bafflement about moral and
political truth. Just answer the question of what my being conscious right now
is, more particularly what your being conscious of the room is, your being conscious in just
seeing the room. Not thinking about just seeing. Not liking it or whatever. You
know the answer in some sense, don't you? You've got the hold.
The answer, lucky or unlucky, was that my being conscious was
the fact of the room being there.
Later on, as you will be hearing, I preferred to say that a room was being there.
You will be more reassured, I'm sure, to hear that that I do
not just discard all that philosophy of mind just glanced at -- the five
leading ideas, and a lot more. On the contrary, it must be that there is
something in it all. It's hard to have a view about the value of consensus in
philosophy, or in science, about what you can call democracy about truth. But
who can say there isn't any value at all?
If you go through the philosophy on qualia, what it's like,
subjectivity, intentionality, and phenomenality, you can have what is the first
of three or four main things in this lecture. You find all those philosophers
using certain terms and locutions. Suppose, as you very reasonably can, that
they or almost all of them are talking about consciousness in the primary
ordinary sense. They think about it in a certain way, have certain concepts, use
certain language for it. It is shared with philosophers and scientists
otherwise concerned with consciousness and with what they call the mind. I am
confident that it is shared with you.
If you put together the terms and locutions you get what we
can certainly call data. You get a database. It is that in the primary ordinary sense, in any of the three
ways, your being conscious now is:
the having of something, something being had -- not in a general sense, the sense in which you have ankles,
hence something being held,
possessed or owned,
your seeing, thinking,
wanting in the ordinary active sense of the verbs,
the experience in the sense
of the experiencing of something,
something being in contact,
met with, encountered, or undergone,
awareness of something,
something being directly or
immediately in touch,
something being apparent,
something not deduced,
inferred, posited, constructed or otherwise got from something else,
something somehow existing,
something being for something else,
something being to something,
something being in view, on
view, in a point of view,
something being open,
provided, supplied,
something to which there is
some privileged access,
in the case of perception,
there being the world as it is for something,
what at least involves an
object or content,
an object or content's coming
to us, straight-off,
something being given,
hence something existing and
known,
something being present,
something being presented,
something being shown,
revealed or manifest,
something being transparent
in the sense of being unconveyed by anything else,
something clear straight-off,
something being open,
something being close,
an occurrent or event, not a
disposition to such events,
something real,
something being vividly
naked,
something being right there,
in the case of perception,
the openness of a world.
That, I say to you, is
data, and I sure bet you it exists in other languages than English. We can
await reassurance from the Germans and no doubt trouble from the Frogs. It is a database. To glance back at the five
leading ideas, it's not a mediaeval technical term in much dispute, or a
philosopher's excellent apercu but
still an apercu, or a familiar or
traditional idea, or an uncertain truth based on words and images, or an
uncertainty about consciousness that seems to slide into unconsciousness.
Without stopping to say more about generalizing about the database,
except that in character it has to do with both existence and a relationship,
is both ontic and epistemic, we can of course note that certainly it is
metaphorical or figurative. To say consciousness is given is not to say it's just like money being given. There is an
equally figurative encapsulation of it all, which I will be using. It is that
being conscious in the primary ordinary sense is something being actual. We can also say that what we have is a
conception of primary ordinary consciousness as being actual consciousness. Can we follow in the history of so much
science by starting from but getting beyond metaphor?
It immediately raises two general questions. What is actual with this consciousness?
And what is it for whatever it is to be
actual? And, remembering what has is being supposed about three parts,
sides or group of elements of consciousness, there are the questions of what is
actual and what the actuality is with each of perceptual, cognitive and
affective consciousness.
So the first two criteria – of 8 -- for an adequate theory or
analysis of ordinary consciousness, a literal account of its nature, is the
theory's giving answers to those questions about (1) what is actual and (2)
what its being actual comes to. Certainly we have to get to the absolutely literal.
We will get better answers, however, if we look at a few other things first.
4 Functionalisms, Dualisms It is prudent, whether or not required by a respect for
consensus, for democracy about truth, to consider existing dominant theories of
anything. If you take the philosophy and science of consciousness together,
certainly the philosophy and science of mind, you must then consider abstract functionalism and its
expression in cognitive science -- computerism about consciousness and mind,
which of course might be or anyway might have been right.
Could it be that abstract functionalism is usefully approached
in a seemingly curious way, approached by way of what has always been taken as an
adversary, traditional dualism? This dualism is the proposition that the mind
is not the brain. That, in a sentence only slightly more careful, is to the
effect that consciousness is not physical. It is, as maintained by many who
have followed Descartes, spiritual. There are, of course, reputable and indeed leading
philosophers and scientists of mind who are dualists. Chalmers is one. There
are other more metaphysically explicit dualists, including Howard Robinson. Has
Block himself been a fellow traveller?
You may excuse me saying of dualism, since I have a lot of my
own fish to fry, that it has the great recommendation of making consciousness different in kind, and the great failing
of making it not a reality. Your
being conscious is something with a history that began and will end. Who now
has the nerve to say it is out of space? It is now real. It now exists. It's
a fact. Evidently all this is bound
up with the clearer and indeed dead clear truth that it has physical effects,
starting with arm movements. This is only denied in Australia,where the sun is
very hot. Elsewhere there is the axiom of the falsehood of epiphenomenalism.
But, however, as the dictionary says, mind is somehow different from matter --
or from some or much matter.
There is no more puzzle about what, in general, abstract
functionalism is. Certainly the elaboration of it in cognitive science has been
rich. Abstract functionalism is owed to a main premise and a large inspiration.
The large inspiration is that we do indeed identify and to an extent
distinguish types of things and particular things in a certain way -- by their
relations, most obviously their causes and effects. We do this with machines
like carburettors, and with kidneys, and so on.
The premise, more important now, is the proposition that one
and the same type of conscious state somehow goes together with or anyway turns
up with different types of neural or other physical states. This is the premise
of what is called multiple realizability.
We and chimps and snakes and conceivably computers can be in pain that goes
with quite different physical states.
My own short story of abstract functionalism, my own objection,
which I skip past, is that a conscious state or event is itself given no reality in this theory that allows it to be a cause
of actions etc. It goes together with traditional dualism in this respect, and
is therefore as hopeless. There is a place within other and very different
theorizing for what you can call physical
functionalism, but that too is not a subject for this evening.
5 Other Theories, More Criteria There are more existing theories and sorts of theories of
consciousness than dualism and abstract functionalism.
My
own list has on it Non-Physical Intentionality and Supervenience, and Davidson's
Anomalous Monism, and the Mentalism of much psychology and science as well as
philosophy, Block in particular, that runs together conscious and unconscious
mentality, and Naturalism, and the important and in a way dominant Representational
Naturalism, and such Aspectual Theories as Panpsychism and Double Aspect Theory,
and Russell's Neutral Monism, and the Physicalisms of Papineau, Searle, Dennett, and of
neuroscience generally, and the Higher Order Theory of Locke and Rosenthal, and the
audacity of the Churchlands maybe now recanted to the effect that it will turn out that there
aren't any beliefs or desires, and the wonderful mystery of Quantum Consciousness,
and finally the general Externalisms -- Putnam, Burge, Noe, Clark.
I save you consideration of and incidental objections to these
existing theories of consciousness, and say only a few things.
One is that while all of these theories are crucially or at
least centrally concerned with the
physical, physical reality, they do not dwell on it. They do not come close
to really thinking about what it is. Was that reasonable?
And just in passing, do these theories concern themselves with
the same question? For a start, was supervenience about the same question of
consciousness that representational naturalism was about?
A third thing is important, indeed crucial, for anyone who
believes, as I do, that there are not proofs
of large things in philosophy, which is a matter of comparative judgement
between alternatives. It is that a good look through those various theories
gives us more criteria for a decent theory or analysis of consciousness -- additional
to answers to the questions you’ve heard of (1) what is actual and (2) what the
actuality comes to.
A decent theory of consciousness, as I have already announced
to you, will indeed have to recognize and explain (3) the difference of consciousness from all else. It will have to give us an unfactitious difference. It will also have to
recognize and explain (4) the reality
of consciousness and the connected fact of its being causally efficacious.
Another condition of adequacy is something just flown by so far in this
talk -- (5) subjectivity, some credible
or persuasive unity, something quite other than a metaphysical self. Another is
(6) the three parts, sides or kinds of
elements of consciousness. It is surprising indeed that the existing
general theories of consciousness do not include in their generality the
distinctness of perceptual, cognitive and affective consciousness. Another
requirement (7) is that of naturalism, essentially a relation to
science. A last one (8) is making sense of the relation
or relations of consciousness to a brain or other basis and to behaviour
and also other relations.
A last thing I should provide here, since I know where this
lecture is going, is a scandalously speedy reminder of just a little more of the theories that are
the externalisms. Putnam said meanings ain't in the head but depend on science.
Burge explained by way of arthritis in the thigh that mental states are individuated
by or depend on external facts, notably that of language. Clark argued that
representation with respect to consciousness is a matter of both internal and
external facts – minds are extended out of our heads -- and Noe theorizes that
consciousness partly consists in acting.
There
is a very, very different externalism.
6 The Objective Physical World To make a good start on or towards the theory we can call Actualism, think for just a few minutes,
whether or not you now suppose this is a good idea, about the large subject of
the physical, the objective physical world. The existing theories of
consciousness, from dualism and abstract functionalism to the externalisms, do
one way or another include presumptions about or verdicts on consciousness
having to do with physicality -- by which they always mean and usually say
objective physicality. Will they come to be judged for their passing by the
subject? I hope so.
Anyway, having spent some time on a database, and flown over a
lot of existing theories of consciousness, let us now spend very little time on
the objective physical world, on what it is for something to be objectively
physical. If there are a few excellent books on the subject, notably those of
Herbert Feigl and Barbara Montero, it is hardly considered at all by the known
philosophers and scientists of consciousness. Or they take a bird’s-eye view,
far above a pedestrian one. Here I’m for walking around, going over the ground.
Let me report convictions or attitudes of mine owed to a respect for both
science and philosophy. I abbreviate what is a substantial inquiry in itself
into the objectively physical to a fast list of characteristics -- which you
will find in the left-side column of the table on the lecture handout [or Powerpoint]. They are properties that can be divided into those
that can be taken as having to do with physicality, the first nine, and those
having to do with objectivity, the other seven.
Physicality
1. Objective physical properties are the properties that are
accepted in science, or hard or harder science.
2. They are properties knowledge of which is owed or will be
owed to the scientific method, which method is open to clarification.
3. They are properties that are spatial and temporal in extent,
certainly not outside of space and time.
4. Particular physical properties stand in lawful connections,
most notably causal connections, with other such properties. Two things are in
lawful connection if, given all of a first one, a second would exist whatever
else were happening. Think about that some other time.
5. Categories of such properties are also lawfully connected.
6. The physical macroworld and the physical microworld are in
relations to perception, diffent relations -- the second including deduction.
7. Macroworld properties are open to different points of view.
8. They are different from different points of view.
9. They include, given a defensible view of primary and
secondary properties, both kinds of properties.
Objectivity
10. They are in a sense or senses separate from consciousness.
11. They are public.
12. Access to them is public, not limited to one perceiver or
other individual.
13.
They are more subject to truth and logic than certain other properties.
14. To make use of the idea of scientific method for a second
time, their objectivity, like their physicality, is a matter of that method.
15. They include no self or unity or other such inner fact of
subjectivity that is inconsistent with the above properties of the objective
physical world.
16. There is hesitation about whether objective physicality
includes consciousness.
So very much more is to be said about all that. Here and
elsewhere it comes to mind to remark that philosophy is as alive and good and with as much future as science -- since it is thinking more about facts as distinct
from getting them.
7 Perceptual Consciousness -- What Is and Isn't Actual Going on now from the database, and the encapsulation of it,
and the pile of theories of consciousness, and the criteria, it seems to me and
others that if we learn from the existing pile of theories of consciousness and
the resulting criteria, and the plain thinking about physicality, we need to
make an escape from the customary in the science and philosophy of
consciousness. There is a fair bit of agreement about that. McGinn is one who really declares it.
We
need to pay our very own attention to consciousness, some untutored attention.
We do not need to turn ourselves into what psychologists used to call
subjects or to demote ourselves to membership of the folk. We do need to concentrate, for a good start, on those two
questions at which we have arrived and respond to them directly out of our
holds on being perceptually conscious. Here is an anticipation, in awful
brevity, of what seems to me the right response.
What is actual for me now with respect to my perceptual
consciousness, my perceptual consciousness as distinct from my cognitive and
affective consciousness, is only a room, what it is sensible to call a room, but a room out there in space, a
room as definitely out there in space as anything at all is out there in space.
God knows it’s not in my head. You can walk around in it, really. And its being
actual is its being in certain clear and specific ways subjectively physical,
its being one of the spatio-temporal parts
or pieces or stages of what we can explain as and call a subjective physical world.
What is actual with you and me now, so far as perceptual
consciousness is concerned, I repeat, is a room, most certainly not a representation of a
room or any such thing whatever, called content or whatever else. What is
actual is a subjective physical world in the sense of a part of it. Saying so
is comparable to familiar talk of being in touch with the world as ordinarily
thought of or the objective physical world in virtue of being in touch with a
part of it.
Is a subjective physical world a phantom world, just a phantom world? Is it
insubstantial, imaginary, imagined? If you are caught in a good tradition of
philosophical scepticism or suspicion gone off the deep end, and feel like saying yes, making
me feel sorry for you, just hang on for a while. Hold your horses.
8. Perceptual Consciousness -- Being Actual is Being Subjectively Physical (in a way) What about question 2? What is a room's being actual?
It
is its existing in a way not at all metaphorical or otherwise figurative, but a
way to be very literally specified. This existence is mainly but not only a
matter of a room's occupying that space out there and lasting through some
time, and of its being in lawful connections including causal ones within
itself, and of two great lawful dependencies that mainly distinguish this way
of existing in particular.
The first is the lawful categorial dependency of what is
actual on what we have just inquired into, the
objective physical world, or rather on parts or pieces or stages of the
objective physical world we ordinary speak of perceiving, whatever that
perceiving comes to. The second dependency with my world is a dependency on my
objective properties as a perceiver, neural properties and location for a
start.
So my being perceptually conscious now is the existence of a
part or piece or stage of a sequence that is one subjective physical world, one among very many, as many as there
are sets of perceivings of single perceivers. These myriad worlds are no less
real for there being myriads of them and for their parts being more transitory
than parts of the objective physical
world. Myriad and momentary things in the objective physical world do not
fail to exist on account of being myriad and momentary. Nothing fails to exist because it is dependent on other stuff. Subjective physical
worlds and their parts or whatever are states of affairs or circumstances, ways
things or objects are, sets of things and properties.
These
subjective worlds are a vast subset, the objective physical world being a
one-member subset, of course of many parts, of the single all-inclusive world
that there is, the physical world,
that totality of the things that there are.
See the middle column of the table in the handout both for subjective physical worlds and their being a subset of subjective
physicality which is itself a subset of physicality in general. You will know
that I pass by a lot of stuff in the table and in what I have to say here in my
hour.
These perceived worlds are about as real, I repeat, in the sum
of decent senses of that wandering word, as the objective physical world, that
other half of the physical world, that other sequence -- however and to what
limited extent the objective physical world is related to subjective physical worlds.
You will guess it is because of the dependencies not only on the objective physical world but also on
perceivers, and for other specific and large reasons, that these perceived
worlds rightly have the name of being subjective.
You can say, then, that my being perceptually conscious now
just is and is only a particular existence of something like what most of the
leading ideas of consciousness and the existing theories of consciousness
half-seem to take or may take perceptual consciousness merely to be of or about, say a room.
If you fancy aphorisms, you can also say Bishop Berkeley wasn't near
to right in saying esse est percipi, to be is to be perceived. The better
aphorism is to be perceptually conscious
is for something in a way to be.
In talking of a subjective physical world, I'm not discovering
a new thing. Just noting and not being
distracted from and using an old thing, putting it into a theory of perceptual
consciousness. There has certainly been talk and theory of some or other physical
world being there for us, in the ordinary
sense of a part of it being there. There's been sensible talk of the world as experienced. There's one for you right now, isn't there?
You're immediately in touch with one of those right now, aren't you? If this
familiar fact doesn't give you a proof of Actualism with respect to perceptual
consciousness, it's a very helpful pull in the right direction.
So much for an anticipation of the main body of the theory of
Actualism with respect to perceptual consciousness, whatever is to be said
about cognitive consciousness and affective consciousness -- including whatever
is to be said of the beliefs and also the desires in which perceptual
consciousness does not consist at all but by which it is often accompanied or
to which it commonly gives rise.
9. Cognitive and Affective Consciousness -- Theories & What Is and Isn't Actual
To turn yet more briefly to these second and third parts or sides of
consciousness, what is actual with your cognitive consciousness, say your just
thinking of your mother or the proposition of there being different
physicalities, or your attending to this room or something in it?
My answer is that what is actual, we need to say, and absolutely all that is actual, is
a representation or a sequence of representations. Cognitive consciousness, to
move from the figurative to the theory, is differently
subjectively physical than with a room. Cognitive consciousness, further,
is related to truth. With respect to affective consciousness as against
cognitive, say your now wanting a glass of wine, what is actual is also
representation, subjectively physical, but related to valuing rather than
truth. See the lecture handout, the right hand column.
If there is a lot of existing
philosophical and scientific theory with respect to perceptual consciousness,
maybe there is still more with respect to cognitive and affective
consciousness. Since I am near the end of my lecturing hour, and discussion is
better, here is no more than just a list of good subjects in another pile, a
list of subjects having to do with representation.
Universal, Pure, and Other
Representationism -- mine, as you know from what has been said of perceptual consciousness as against cognitive
and affective consciousness, is not universal. As you will be hearing in a minute or two, it
is also not pure either.
Our Knowledge of Thinking and Wanting --
and Linguistic Representations.
Linguistic Representations -- a Simple
Classification.
Languages of Thought. Fodor.
Evolutionary Causalism, also known by
other names, for example as Biosemantics. Millikan and Papineau.
Relationism or computerism. A whole industry.
Lingualism, as I call it, philosophy of
language applied to philosophy of mind. Searle is the champion.
The Durable Truth of Some
Representationism or Other.
Dependency, Convention, Unicorns -- how
conventions come about and so on Searle again. His perfect Chinese Room Thought-Experiment and whether it's an argument for Actualism.
10 Cognitive and Affective Consciousness -- Being Actual is being Subjectively Physical (In a Way) But to say just a few words of some of that, the
representational theories of and related to cognitive and affective
consciousness admittedly do begin from reflection on our spoken and written
language, English and the rest, linguistic representations, and in effect move
on from that reflection to an account of conscious
representation. I report that it seems to me that none of it by itself works.
Absolutely plainly, there is a difference between a line of type on a page or a
sequence of sounds and a conscious representation or a sequence of such things.
Actualism saves the day. The greatest of philosophers
in our tradition, David Hume, began or more likely continued a certain habit of
inquiry when he was in a way frustrated in coming to an understanding of
something, in his case cause and effect. 'We
must...,' he said, 'proceed like those, who being in search of any thing, that
lies concealed from them, and not finding it in the place they expected, beat
about all the neighbouring fields, without any certain view or design, in hopes
their good fortune will at last guide them to what they search for'. Pity he
didn't get to the right answer about cause and effect, but let us be hopeful in
our own different endeavour. In fact we have more than good reason for hope.
Our maybe reassuring
circumstance right now is that if we need to look in another field than the
two-term relation of representation, we can in fact do that without going to a
wholly new field. If we have to leave the field of thoughts and wants and of
representation when it is understood as being somehow only a relation between
the representation and what is represented, we can in fact do that, by way of
another field that is not a new field.
I mean we can stay right in
and attend to the larger field that we've never been out of, always been in
since before getting to cognitive and affective consciousness. Never been out
of it since we began by settling our whole subject-matter of consciousness in
general, since we settled on an initial clarification of consciousness in the
primary ordinary sense -- consciousness as actual, actual consciousness. The
smaller field is in the larger.
Cognitive and affective
consciousness, thoughts and wants, are not only representations as first
conceived in relation to spoken and written language. They are not only such
representations, most saliently propositional attitudes, attitudes to
propositional contents, the latter being satisfied by certain states of
affairs. Rather, thoughts and wants are such
representations as have the further property of being actual. That is the
burden of what I put to you. Representational consciousness consists in more than a dyadic relation.
For the contents of that contention, you will rightly expect
me to refer you again to that table -- to its list of the characteristics of
subjective physical representations. The right-hand column.
Questions and objections are
of course raised by Actualism. One is prompted by the recent history of the
philosophy of consciousness and some of the science of it. Supposedly
sufficient conditions having to do with consciousness, it is claimed, fail to
be such. Do you simply say about
Actualism that exactly the conditions for consciousness now set out in
Actualism -- say perceptual consciousness -- could be satisfied by something
but the thing still wouldn't be conscious?
There is a
temptation to say a kind of replica of me or you that it could satisfy exactly
the conditions specified and the replica wouldn't be conscious in the way we
know about? That it would be, in this different setting of reflection, just one
of those things we were got to think about earlier, a zombie ? Putting aside
the stuff about metaphysical possibility and all that, which I can do pretty
easily, do you say it could be something without consciousness despite it and
the rest of the situation being exactly what actualism says is what being
conscious consists in?
Well, sometimes the best form of defence is counter-assertion
because it is true.
In the heatwave of the
English summer of 2013, at a gents club, a medical man gave me a free opinion
about diabetes. It led me, after reading up on the internet that the symptoms
are thirst, tiredness, seeing less clearly and so on, to the seemingly true
proposition about me that I had a lot of the symptoms. I fell into the illusion
that I had diabetes -- the diabetes illusion. Think of those propositions about
myself as counterparts of the 16 propositions on the checklist on the
physicality of subjective physical worlds and hence on perceptual
consciousness.
Is it an illusion that they
do not capture the nature of
perceptual consciousness, that there is something else or something more to
consciousness? Do you share with me at least on most days the idea that a
persisting elusiveness of perceptual consciousness is an illusion? That it just is
an illusion that there is more to
consciousness than we have supposed, more that we have got hold of? I hope so.
You may need to keep in mind all of the characteristics in the table of perceptual
consciousness and the other two kinds. Keep in mind too that there are more kinds of
illusion than personal ones.There are illusions of peoples, cultures, politics,
political classes, philosophy, and science. Maybe it will be possible to see more in the end about
the more-to-consciousness illusion.
It is pretty certain, and I'd say ordinary reflection and the
history of the philosophy of mind proves it if you need what you call a proof,
that there is at least strangeness about consciousness. More than difference
and uniqueness. Consciousness seems to be, they say, a trick we can't
understand. McGinn again. If
that's right, what you need in order to make sense of it is exactly something
strange that makes sense. Something that isn't strange won't be true to the
hold we have on consciousness. We aren't just ignorant. We know there is a
strangeness.
Do you now maybe change your tune? Do you
say that this externalism of mine, so-called, isn't crazy, in need of exclamation marks, rhetorical, circular,
against good sense, strange, or in one of the other ways unsatisfactory? Those
were more of Colin's ideas about a premature predecessor of the present Actualism.
Do you say more or less the opposite -- that Actualism is old hat, or at least
half old hat? That what it comes to is philosophically some familiar idea --
say that perceptual consciousness has content, with the addition, no doubt
already made by somebody else, that the content is external?
Well, Actualism doesn't come to that,
even with just perceptual consciousness before we get to reflective and
affective consciousness. What it comes to, in terms of a headline, is that the
consciousness is
the fact of an
existence of the content, the content out there -- a content properly
conceived and described. There's
no more to the fact of being perceptually conscious in this way than
dependent
external content. No vehicle or any other damned thing in that variety
glanced
at, including a funny self, direction. None of it except representation
and attitude in cognitive or affective consciousness either.
Do I have to try harder here? Will some
tough philosophical character say that there is no news in all this verbiage?
That Actualism is blunder from Bloomsbury? Will he say that it is a truism that
we all know that the world, something close to the objective physical world as
defined, is part of, maybe the main thing with, perceptual consciousness as
somehow ordinarily understood, with another main thing in the story of it being
some kind of representation of it?
Well, I don’t mind at all being in accord
with some or other truism of this sort. But it would be strange to try to
identify Actualism with it, try to reduce Actualism to it. Actualism is the
contention that the being perceptually conscious is itself precisely a defined
existence of an external world. Actualism is absolutely not the proposition,
say, that what the story of perceptual consciousness comes to is the objective
physical world and also representation, seemingly some kind of represented world
-- what does seem to be a kind of
phantom world.
Actualism
sure isn't naive or direct realism
either, mainly just against sense-data and all that, and to the effect
that in perception we're in some unexplained relation to the objective
physical world. Actualism isn't any other externalism either. And
we haven't just engaged in what
is often called semantics -- just
made a change in the use of a word for some purpose. We haven't just
transferred the noun 'consciousness' from a state in a perceiver or from a
relation of that state to an outer thing -- transferred it to an outer thing on
the end of the mentioned relation.We have a different view of what is out
there, its subjective physicality, and it has no relation or anything else in
it.
Further, whatever you think of it,
there's a completed argument for all that stuff. Of course there's that other
question. Is this the consciousness we should be thinking about? Should we be
thinking about what it is to be conscious in the primary ordinary sense? Is
this the right or the useful subject? You know what I say. Hold your horses.
11 Conclusions Past and Present So we have seen something of
the satisfying of two criteria for a decent theory or analysis of consciousness
in the primary ordinary sense, which is to say that consciousness clarified as
actual consciousness. We have seen something of answers to the questions of
what is actual and what actuality is. There remain other criteria. I pass by
all that. I just put it to you that Actualism does very well with the criteria
of reality and causation, difference in kind, subjectivity (of which I'll say just a word more), the three sides of consciousness, naturalism, and the relations of
consciousness.
It is my own attitude, then,
that Actualism is a defeat of pessimism
about understanding consciousness. More needs to be said about Chomsky in
particular here – but that is for another day. Chalmers’s hard problem of
consciousness, if Actualism works as well as I propose, is just solved. There
is also the hope that Actualism makes explicit and real sense for the devotees of Naive Realism. There is also the
hope that it liberates consciousness science from a common hesitancy, being baffled about science. It also sure
does for slightly mad neuroscence-with-philosophy, say that of Popper and
Eccles or Libet. Also, does it make more than a contribution to an old
chestnut, the subject that is determinism's consequences for freedoms and
responsibilities? You'll have to read the book to find out about that.
There remains a last matter here.
Was ordinary consciousness in the primary ordinary sense the right
consciousness to consider? My short answer cannot be yes, since there is no
possibility of showing that any consciousness is the right one.
In
the free world of
philosophy, so much freer than the free world we hear more about,
anyone can follow the crowd that considers the consciousness that
in our terms consists in both ordinary-consciousness mentality plus
mentality
that is not ordinary-consciousness mentality. They can be still freer
and
consider consciousness where it also includes the such facts of
perception as
those having to do with retinas. They can consider consciousness that
consists
in our perceptual consciousness plus
the cognitive and affective consciousness that consists in the large fact of
attention. They can consider consciousness in general without distinguishing
our perceptual consciousness from our cognitive and affective consciousness.
One thing that maybe can be
said for our choice is that no inquirer can leave out ordinary consciousness,
of which we have a clarification. This consciousness must surely be, it is, what serves to identify the other
additions, most obviously the addition of the mentality that is not ordinary
consciousness. This combined subject needs to be distinguished from other
explanations of behaviour, say mere musculature, and it cannot be distinguished
without reliance on ordinary consciousness. If Actualism is a defensible theory
of ordinary consciousness, no general theory can leave it out. I don’t think
that is true of any other initial idea of consciousness
The conclusions are the
result not of proof, for which philosophy as against science is too
hard, but of the weight of argument and judgement. Actualism, it is hoped, is a
case of satisfying Hume's hope -- an inescapability of conclusions given
prior acceptance of at least reasonable premises. It is mainstream philosophy,
a greater concentration than that of science on the logic of ordinary
intelligence -- on clarity, consistency and validity, completeness, and
generalness. Hopefully it is fertile or pregnant thinking.
