We
can go back to the 18th century and to Thomas
Reid to see what appears to be a reference to what is now called
“non-conceptual content”. Reid
wrote:
“[S]ensation, taken by itself, implies neither the conception nor the
belief of any external object. [] Perception
[on the other hand] implies an immediate conviction and belief of
something external.”
Now
let's jump to the first half of the 20th
century, when “sense-data theory” was in fashion. An experience
of a sense-datum was seen in non-conceptual terms. It is of course
true that this position was problematic in many ways. As Michael
Williams puts
it:
“It
is important to see that acquaintance with sense-data is 'direct' or
'immediate' in two senses. Not only is it independent of any further
beliefs, it is pre-conceptual.
It makes propositional knowledge (involving conceptualisation)
possible.”
Now
we can jump forward to another distinction offered by Laurence
BonJour. He argues that what he calls “sensory content” is not in
fact “propositional or conceptual in character”.
*************************************
If
we return to the sense-datum of a red patch.
That
must have meant (i.e., to sense-data theorists) that a red patch
sense-datum is firstly experienced and only then perceived as a
red patch. That is, the concepts [red] and [patch] are applied to the
red patch. (What is meant by “applied” here?)
Thus, the sense-datum of a red patch is a basis
of later knowledge, not an example
of knowledge itself. It can become conceptual. So there's no reason
to believe it is
incorrigible, direct, immediate, pure or anything else like that. The Given is only seen as the Given
after the fact.
Following
on from that, this raises the possibility (or actuality) that even if
we accept non-conceptual content, we may still go wrong when we
describe it. However, how would we (or anyone else) ever know
that? Here we have another problem: the problem of private mental
states. (In this case, private sensory content.)
As
for BonJour's position.
We
can say that such “sensory content” can
become
conceptual content. And only then can it (as Michael Williams puts
it) “justify
basic beliefs”.
More simply: sensations cause
beliefs (i.e., they aren't themselves beliefs). This is a position
which will be defended later.
This
question must now be asked:
What
is the precise nature of the movement from non-conceptual content to
conceptual content?
Animals
It
can be argued that some animals have the same “non-conceptual
content” as human persons – at least in certain cases. It's just
that we can (or do) apply words or concepts to that very same
content. This is a position expressed (if not endorsed) by Alex Byrne
when he states
the following:
“Some
of the perceptual states of lower animals have contents in common
with human perceptual states.”
We
can of course ask (in tune with philosophers like Daniel Dennett) how
we could ever know (or even surmise)
that
“animals
have contents in common with human perceptual states”. On the basis
of their behaviour? (How would that work?) On the basis of their
evolutionary proximity to human persons?
In
any case, Martin Davies also allows animals non-conceptual content
when
he says that
“human infants and certain other creatures” are
“arguably [ ] not deployers of concepts at all”. More
specifically, this perceptual content is free “of any judgement
that might be made”.
We
can also take the position of Brian Loar.
Let's
talk about a dog called Fred.
According
to Loar (not his own example), Fred “picks out a kind” - the
kind human
beings call
“human beings”. More correctly, Fred picks out a particular (say,
Mike) and sees that he/it belongs to the kind we call (though it
doesn’t) human
beings.
At no stage of the game is Fred’s x
is F
anything like our x
is F.
That is, it's not linguistic or sentential.
So how close must Fred’s x
is F to our x
is F?
More relevantly, why do we demand an exact parallel with our x
is F
in order to allow attributions of concepts and beliefs to dogs and
other animals?
Having
put the dog's position, it doesn't appear to be an argument for
non-conceptual content in that Loar says that Fred (the dog) “picks
out a kind”, etc. Clearly, noting or picking out kinds (even if
non-linguistically, etc.) doesn't seem like a candidate for
non-conceptual content.
Nonetheless,
something
(or some things)
must also come before the linguistic expressions of human persons:
both as a species and as individuals. Our linguistic expressions
didn’t occur ex
nihilo.
Here’s
Paul
Churchland
making
related
points:
“[L]anguage
use is something that is learned, by a brain already capable of
vigorous cognitive activity; language use is acquired as only one
among a great variety of learned manipulative skills; and it is
mastered by a brain that evolution has shaped for a great many
functions, language using being only the very latest and perhaps the
least of them. Against the background of these facts, language use
appears as an extremely peripheral activity, as a species-specific
mode of social interaction which is mastered thanks to the
versatility and power of a more basic mode of activity. Why accept,
then, a theory of cognitive activity that models its elements on the
elements of human language?”
Peacocke,
Davies and Tye
One
direct case of purportedly non-conceptual content is offered up by
Christopher Peacocke when he
writes the
following:
“Only
those with the concept of a sphere can have an experience as of a
sphere in front of them."
In
detail:
“The
natural solution to this... quandary is to acknowledge that there is
such a thing as having an experience of something as being pyramid shaped that does not involve already having the concept of being
pyramid shaped.”
This
is problematic in that there may still be concepts involved in this
experience. That is, it may still be what Peacocke calls
“object-involving”.
In any case, this person (or animal) has an experience - and even an
experience of a something
(x).
It's just that he (or it) doesn't have an experience “as of
a
sphere”. It's a sphere to us; though not to him (or it).
Elsewhere,
Peacocke says
that the
“content
of experience is to be distinguished from the content of a judgement
caused by the experience”.
In
our example, this would be a judgement that x is a pyramid.
In
basic terms, the “content of experience” and the“judgement”
don't occur at precisely the same time. Whether this temporal way of
looking at things makes sense (or is acceptable) is another matter. I
say that because it can argued that the experience and judgement
occur at one and the same time.
Peacocke
also sets up a relation between the non-conceptual and the conceptual
when he
says that
“thought
can scrutinise and evaluate the relations between non-conceptual and
conceptual contents and obtain a comprehensive view of both”.
This
question must again be asked here:
What
is the precise nature of the movement from non-conceptual content to
conceptual content?
Colin
McGinn points out the position represented by philosophers like
Peacocke when it comes to “representational content”. McGinn says
that they accept
“prerepresentational
yet intrinsic level of description of experiences: that is, a level
of description that is phenomenal yet noncontentful".
Peacocke
himself says that “sensational properties do not determine
representational content”. (Peacocke cites an example of an array of
dots which can be seen as either vertical
or horizontal rows1 and Wittgenstein's duck-rabbit
seems to be relevant too.) Concepts are part of this story.
More
specifically on representation, Peacocke says
that the
“representational
content of a perceptual experience has to be given by a proposition,
or set of propositions, which specifies the way the experience
represents the world to be”.
Does
Peacocke mean something linguistic or something abstract here? Does
he mean that these propositions need to be articulated or verbalised?
And why do we need propositions at all in these cases?
Peacocke
also appears to make a mistake about a supposedly non-conceptual
experience.
He
says
that a person
“waking up in an unfamiliar position or place [will have] minimal
representational content” . Yet surely unfamiliarity doesn’t
entail lack of conceptual or “representational content”. This
person may still conceptualise his “unfamiliar position or place”.
Perhaps this only displays Peacocke’s linguistic or propositional
bias. This person may not describe or form “propositional
judgements” about his unfamiliar position or the new place he finds
himself in. However, that may be irrelevant to conceptual and/or
representational content.
To
summerise
Peacocke's position:
sensation
⟶
perception ⟶
judgement
Martin
Davies too makes an explicit distinction between what he calls the
“perceptual content of experience” and the having (or possession)
of concepts. In
detail:
“[T]he preconceptual content of an experience is a kind of
non-conceptual
content. What this means is that a subject can have an experience
with a certain perceptual content without possessing the concepts
that would be used in specifying the content of that experience.”
Thus,
in Davies's jargon, the “perceptual content of experience” comes
first, and only then are concepts applied to it. Indeed, it seems
possible that this perceptual content of experience may remain (as it were) free of concepts.
Davies's
perceptual-content idea is even more radical in that it “is
not object-involving”.
The basic point here seems to be that non-conceptual content can't
(by definition?) be object-involving.
Martin
Davies also divorces perceptual content from the “representational”.
That is, the non-conceptual implies (to me at least) the
non-representational. According to Davies, that non-conceptual
“substrate” is added to by a “representational superstructure”.
In addition, the “sensational” is also distinguished from the
“representational”.
Finally,
Michael Tye also makes a temporal division when he
says that
“visual
sensations feed into the conceptual system, without themselves being
a part of that system”.
One
can now ask how “visual sensations” can “feed into the
conceptual system” without having some kind of vital connection to
that system. And if they have such a connection, then can they still seen as non-conceptual? That is (as asked twice before), what is the precise
connection (or link) between the non-conceptual (visual sensations
in this case) and the conceptual system? One is tempted to infer (as
with John McDowell) that in
order for these visual sensations to be able to feed into the
conceptual system, then they must share something with that system. Otherwise how does that system distinguish irrelevant sensations from relevant ones?
Despite
that, according to Tye, “phenomenal content” is by definition
non-conceptual. And he too
(like Peacocke) gives us his own division between “phenomenal
content” and belief. Thus we have:
“A
content is classified as phenomenal only if it is nonconceptual and
poised [for use by the cognitive centres].”
And:
“Beliefs…[which]
lie within the conceptual arena, rather than providing inputs to it.”
Here
“phenomenal content” is seen as input
to be worked upon later. Beliefs, on the other hand, are outputs. Is this phenomenal
content
“the Given”? It certainly seems to be when Tye made the epistemic
point that phenomenal content is “poised for use by the cognitive
centres”. That is, it comes (epistemically) before such “use”.
We
also have an explicit tying of concepts to language from Tye when he
writes
the following:
“Having
the concept F
requires, on some accounts, having the ability to use the linguistic
term 'F' correctly.”
Yet
Tye also cites mental content that is non-linguistic when
he says that
“after-images,
like other perceptual sensations, are not themselves thoughts or
beliefs; and they certainly do not demand a public language”.
It's
very hard to see afterimages as
conceptual. Then again, afterimages are a very special case of
mental content. That is, afterimages don't seem to be relevant to
this discussion because they're unlikely (or rarely) to be the basis
of later conceptual content.
Critics
of Non-Conceptual Content/the Given
Wilfrid
Sellars
Wilfrid
Sellars (in his 'Epistemic Principles') lays his critical cards on
the table when
he said
the Given
“would
be a level of cognition unmediated by concepts; indeed it would be
the very source
of concepts”.
Sellars
was right to imply here that there can't be a “level of cognition”
which is “unmediated by concepts”. However, we needn't also
conclude (or accept) that these sensations can't be a “source of
concepts”. The problem is that Sellars fuses cognition with
non-conceptual content. Yet the two needn't go together. Indeed not
even an old-fashioned believer in the
Given
would have believed that. And isn't that why non-conceptual content
is a (to use Sellars' own word) “source” of cognition and
concepts, not an example of these things?
Incidentally,
Sellars himself did make a distinction between the two when he said
that a
“sensory element [of perceptual experience] is in no way a form of
thinking”. So Sellars happily concedes a “sensory
element”. Having said that, that sensory element
may not come first. It may simply be part of the perceptual
experience from the very beginning.
John
McDowell
John
McDowell explicitly believed that the acceptance of non-conceptual content is
effectively a rebirth of “the myth of the given”. McDowell is now
well-known (i.e., within epistemology) for holding this position.
That is, for his rejection of the idea that we have a temporal
division (as I see it) between the mind being presented with a
non-conceptual Given, and then a later application of concepts to
that Given.
McDowell
himself writes (in his Mind
and World):
“[T]he content of a perceptual experience is already conceptual. A
judgement of experience does not introduce a new kind of content, but
simply endorses the conceptual content, or some of it, that is
already possessed by the experience on which it is grounded.”
What
does McDowell mean by “simply endorse the conceptual content”
(i.e., apart from claiming that the content is already conceptual)?
What does McDowell mean by “already conceptual” here? How does a
concept-based “judgement” differ from the already conceptual
“content of a perceptual experience”? And isn't all this
dependent on what philosophers take concepts to be?
So
McDowell believes that we're fooled into believing that there's such
a thing as non-conceptual content. In the case of “rich”
experiences (such as when we don't have the words or concepts for
particular shades of colour), it's nonetheless the case that we have
a “a
recognitional capacity, possibly quite short-lived, that sets in with
the experience”.
(This
is similar to the stress which David Lewis made on “recognitional
capacites”
when discussing the what-Mary-didn't-know
scenario. That is, Mary doesn't "acquire any new facts". However, she
does acquire new recognitional
abilities.)
Despite
all that, it's hard to see a situation in which having a
“recognitional capacity” can ever be mistaken for a
non-conceptual state by so-called “non-conceptualists”. After
all, McDowell argues that it's fully conceptual. So perhaps McDowell
is wrong to assume that this is an example of a conceptual state
mistaken (by non-conceptualists) for a non-conceptual state. In other
words, don't non-conceptualists have something more basic in mind
when they refer to non-conceptual content?
A
Rich Experience
It's
often said that an experience which is “rich” can't be entirely
conceptual. For example, Alex Byrne
quotes
a fictional
person saying:
“It
appears to me that my environment is thus-and-so.”
And
who then says:
“So I suppose the
content of my experience is
rich/perspectival/phenomenal/non-conceptual.”
I'm
not sure if this is a good way of putting it because if the environment is seen to be "thus-and-so”, then doesn't that imply that
it's not “non-conceptual”?
Anyway.
The above is a simple way of saying that this person had an
experience of a particular environment which he couldn't completely
describe. Or, rather, at the actual time of the experience he didn't
describe it; though afterwards he may well have been able to do so.
Nonetheless, even after the experience, there would still have been
elements of that environment for which he has no words or concepts.
So
does this show that this experience was at least partly
non-conceptual?
Here's
another description of a
rich
experience from Christopher Peacocke:
“Our
perceptual experience is always of a more determinate character than
our observational concepts which we might use in characterising it. A
normal person does not, and possibly could not, have observational
concepts of every possible shade of colour...”
Can
we say that an experience is “more determinate” even if it's not
conceptualised in any way? In what sense, then, is it determinate?
Here there's a hint at a kind of discrimination which doesn't involves concepts, let alone words or descriptions.
Despite
that, even if a person has no “observational concepts” or words
for “every shade of colour”, that person is said to still note
the unnamed shades of colour. But how is that possible without
concepts? Perhaps the problem is tying concepts too closely to public words. Surely
an animal (say, a dog) can discriminate without public words or
“observational concepts”.
Bill
Brewer articulates this point in
the following:
“For
surely a person can discriminate more shades of red in visual
perception, say, than he has concepts of such shades, like 'scarlet',
for example.”
That seems to be the case. However, according to Brewer, the “conceptualist”
has an answer to this. It is to
“exploit
the availability of demonstrative concepts of color shades, like
'thatr
shade',
said or thought while attending to a particular sample, R”.
As
can be seen, this is still language-fixated in that although there
are no public words for these colour shades, this person is still
saying “thatr
shade” to
either himself or to another person. Surely this rules out any discriminations an animal may make.
So
here we may have a “fineness of grain” (or “richness”)
without concepts or judgements that implies a level of discrimination which occurs without concepts - or at least without
words.
Of
course one can apply concepts or words after
the fact.
One can even invent one's own neologisms for experiences or colours
one doesn't know the name of. But we may still have had an experience
of the colours without using concepts or words.
We
can now go beyond talk of the different shades of colour and say, as
Gareth
Evans
did,
that perception itself always (or often) has a “phenomenological
richness” which goes beyond the concepts used in perception. In
other words, experiences or perceptions are more fine-grained than
can be accounted for by simple references to the many different
shades of colour. Indeed, phenomenologically, an experience is
almost infinitely rich (or detailed). And even if we had public words
for everything within it, such words would still never be used during
the actual experience itself.
Davidson on Causes and Sensations
It
may be useful to press-gang Donald Davidson into this debate.
Whereas
we can stress non-conceptual content, Donald Davidson himself
stressed the “causes” of what he called “sensations”. So, in
this picture, the causes of sensations can be said to take the place
of non-conceptual content.
In
the following passage (from his paper 'A
Coherence Theory of Truth
and Knowledge')
Davidson
wrote:
“The
relation between a sensation and a belief cannot be logical. Since
sensations are not beliefs or other propositional attitudes. What
then is the relation? The answer is, I think, obvious: the relation
is causal. Sensations cause some beliefs and in this sense are the
basis or ground of those beliefs. But a causal explanation of belief
does not show how or why the belief is justified.”
So
it's worthwhile rewriting this passage for clarification and to put it within
the context of non-conceptual content. Thus:
The
relation between “sensations” (or non-conceptual content) and beliefs cannot
be logical. Since sensations are not beliefs. What then is the
relation? The answer is, I think, obvious: the relation is causal.
The world causes non-conceptual content (or sensations) and in this
sense is the basis or ground of concepts (or conceptual content) and
beliefs. But a causal explanation of non-conceptual content (or
sensation) doesn't show how or why judgements about it are true or
false of the world.
Another
passage (from the same paper by Davidson) is even more apposite
in this
context.
Davidson wrote:
“Accordingly,
I suggest that we give up the idea that meaning or knowledge is
grounded on something that counts as an ultimate source of evidence.
No doubt meaning and knowledge depend on experience, and experience
ultimately on sensation. But this is the 'depend' of causality, not
of evidence or justification.”
Here
again we can rewrite Davidson in the context of our take on
conceptual and non-conceptual content. Thus:
I
suggest that we give up the idea that conceptual content (or belief)
is grounded on something that counts as an ultimate reality: either
non-conceptual content or the world. No doubt conceptual content (or
beliefs) ultimately depend on non-non-conceptual content (sensations) or
the world. But this is the 'depend' of causality, not
mind-independent truth or fact.
In
Davidson's terms, conceptual content causally “depends” on
non-conceptual content (or sensations) and the world (or causes).
However, that non-conceptual content or world doesn't - and can't -
in and of itself guarantee us truth. Thus it can't be seen as the
Given
in the 20th century sense.
In
that case, perhaps we can say that our causal interactions with x
are the
Given;
though not the beliefs these causes bring about. In that case, as
Susan Haak says,
it is
“only
propositions, not events [or objects], that can stand in logical
relations to other propositions [or beliefs]”.
The
causal interactions (or non-conceptual content/sensations) themselves
are neither beliefs nor propositions. Therefore they can't “stand
in logical relations to other propositions” or beliefs. The causal
interactions (or sensations) are causes of beliefs; though, in and of
itself, they are neither evidence for such beliefs nor justifications
for further beliefs.
In
any case, the same causal context - taken only in itself - can cause
different beliefs in different people and possibly different beliefs
in the same person at different times. The interpretations of our
causal contacts depend on our prior beliefs and the prior concepts
which we apply to our causal interactions. And even if a particular
causal contact brings about the formulation of new beliefs or new
concepts, these will still be dependent upon - or be related to - prior
beliefs and prior concepts.
Conclusion
To
sum up. It can be said that surely there must be some kind of Given
in order to get the ball rolling.
Thus
in Davidson's scheme we had:
causes
⟶ sensations ⟶ beliefs
instead
of the more basic:
sensations
(or non-conceptual content) ⟶ beliefs (or conceptual content)
Alternatively:
i)
An experience of x.
ii)
Then an experience of
a
[?].
Or:
i)
Sense experience x.
ii)
Then sense experience x
+ conceptual content (or plain concepts).
We
can now say that i) and ii) may not, or cannot, occur at one and the
same time.
Thus
“the Given” needn't remain given. That is, i) becomes ii).

1)
Christopher Peacocke's example of a "sensational substratum" of either three vertical columns or four horizontal rows doesn't seem to work. He says that "we see the array as three columns of dots rather than as four rows". However, isn't that simply because the dots in the columns are closer together than the dots in the rows? If the distances between the dots were identical in both cases, then what would we "see"? The image at the top of the page is more balanced than Peacocke's own example in this note.
