Quite a title for what will actually be a slim post! Here's the
sitch—we're trying to answer the question why certain
"imagings" of images or sentences hold our attention and are
experienced as contentful, telling us things, when "this is
an illusion", because "images are not missives sent from oneself to
oneself".
Here is a possible answer. Suppose that one's mind
includes many system,s attentional, computational (comprised of
many task specific computational modules), memorial, affective,
visual, auditory, speech-producing and consuming, and so on. One
also has self-monitoring systems, built to register bodily states
and needs … The information stored and processed
continually by all these systems is quite enormous; but attention
is limited, as are resources … In this competition for
agential, person-level, resources, it gives an attitude, a need,
or an emotion a decided edge if it can cause representations that
have a powerful pull on the attention. The attention is commanded
by representations with auditory and visual aspects, and held by
information that tells a coherent story. So if a desire can cause
an image or images that catch and hold the attention, relevant
systems of intention-formation may more readily engage in ways
favorable from the perspective of the desire. … No agency
needs to design the image so that it speaks just so about the
desire. It is enough that having such effects in creature
[sic] like us is a way for desires to get their way with
us.
All this is from p 64 of Krista Lawlor's "Knowing What One Wants"
and it is, seh allows, "entirely speculative". But if this is the
account she's going to go with, it seems to open up some territory
that ought to be acknowledged and addressed. (Does one address
territory?) The account is evolutionary in spirit, I take it, in
that desires need not to be conceived of as having designs or being
capable of fashioning actual messages to us, it's just that
the desires that happen to cause representations that are as-if-of
the things the desires themselves are concerned with fare better in
actually being acted on than other desires do, so … something
something evolutionary pressure, I suppose; there seems to be a
missing element to the story, given that there isn't a notion
of reproduction at play that would explain why desires
would come more often to tend to cause imagings that catch and hold
the attention and that correspond in some systematic way to what the
desires are of. Given a soup of desires, one that tended to catch
and hold the attention might meet with greater success than the
others, in that intentions and actions would be formed and performed
that led to the desire's being fulfilled. But that doesn't mean that
it will transmit that same tendency to its successor desires,
whatever that notion might mean. Whatever, though; let us wave our
hands over that question in the manner prescribed by ritual and
custom. Here's a more interesting issue.
We know from the evolution of creatures that some of them are both
poisonous and brightly colored, the coloration serving to warn
predators of the poison. (Handy at the individual level, one must
admit.) And one knows also that some other creatures have (as it
were, not by design, etc.) cottoned on to the utility of bright
coloration and taken the shortcut of just being brightly colored,
and omitted to actually be poisonous—so much work! The
coloration gives you most of the benefit of being both brightly
colored and poisonous at a fraction of the cost. Couldn't something
similar happen with desires, on this sort of account? The benefit
that accrues to a desire that
p of catching and holding the
attention and intention is the benefit of my actually bringing it
about that
p, fulfilling the desire; this, however, will be
a benefit to any desire that would be fulfilled by my doing whatever
it is I'll do to bring it about that
p, i.e.,
not
only by desires actually about
p. Suppose I
harbor the perverse desire to degrade the soles of my shoes;
couldn't it catch and hold my attention by causing representations
as if of the pleasantness of going for long walks? Going on the
walks will also affect my shoes, and such a representation might
actually be more reliable, from the perspective of this desire, than
a representation of the pleasures of down-at-the-heels shoes, which
would be apt primarily to puzzle me. The desire that
q,
which I find distasteful, might clothe itself in representations
of
p, which I find more reasonable. Of course this
as-it-were strategy is not without its risks, since I might hit on a
way of bringing it about that
p that
doesn't
bring
q about too, but it might on the whole be as it were
worth it to the desire that
q, depending. So there seems to
be a question, on this account, that faces any would-be agent
inferring from representations to the desires that supposedly caused
them: were these representations of doing
this caused by a
desire with the selfsame content (is
that what I desire)?
Or were they caused by a more vulpine desire, which comes to me with
ovine representations? How could one tell? One might think that
Lawlor is actually acknowledging this possibility, albeit not
drawing attention to it, when she writes that "typically causing
the right kind of images gets the desire a better chance of being
fulfilled." One will likely assume, on first reading, that "the
right kind of images" means the kind of images that will be
interpreted to have the same content the desire has. But if the
point of these images is to catch and hold the attention and thereby
make more likely the undertaking of actions that will get the desire
fulfilled, the right kind could well be quite other.
And for Lawlor, I think, the question is, suppose that the
representations as if of doing p were actually caused by a
desire that q, but the agent doesn't know this, and
self-ascribes a desire that p. The agent might even then
(mightn't she? if not, why not?) experience the "characteristic
changes" (p 62) in her imagings that show the question to be
settled; she experiences a "sense of ease" (p 59), the attribution
"sticks" (p 57). What should we conclude about her? That
despite the actual cause of the representations, her inference that
she desires that p is correct? I'd be inclined in that
direction, but I'm unmoved by Lawlor's position and paper overall
anyway. If we do say that, then how do we justify it? If, on the
other hand, we prefer to say that she's just mistaken, and
really doesn't desire that p, only that q, then
what are we to make of her ease, the attribution's stickiness, etc.?
(Maybe we're to deny that in this case it could really happen that
way.) The (limited, piecemeal) discussion of the
attribution's sticking, once made, and the "characteristic
changes" and whatnot after the reflection and inferring, seems to me
to be a weak point in the account, one that serves as a
bactrio-nasal inlet. This question doesn't actually, I suppose,
require the possibility of the kind of mimicry described above
(though I do think that's worth addressing)—the agent could
just misinterpret the representations the desire
that q caused along p-lines and find herself at
ease with that interpretation. (Right? Or, again, if not, why not?)
Maybe "misinterpretation" isn't really the right term, since by
hypothesis these representations (and even "representations" isn't
the right term, for the same reason) aren't messages or any kind
of interpretandum in the first place—but the imaging
characteristically caused by a q-desire can't guarantee its
being taken qishly.
A bit later Lawlor writes that "whether or not one's
desire actually causes one's imagings and other internal
promptings is a separate question. The point I note here is that our
inference is structured in such a way as to suppose that
desires cause imagings and other internal promptings" (p 65). But
how could this be a separate question? It seems rather central to
me; if we're engaging in some kind of causal inference from an
internal prompting to the existence of a desire that caused it, then
the soundness of the inference seems to depend quite a bit on the
desire's actually having caused the prompting. If the inferential
pattern merely supposes that there are such causal
relations, then, on the one hand, something that I take it is
necessary to separate Lawlor's position from one like Taylor's,
namely that the desire in question definitely already
exists and is therefore decidedly not constituted by
the interpretive activity of the agent is free to go by the wayside.
(Lawlor wants to distinguish the inferential account from a
constitutive account, and also describes the cognitive element of
the inferential account. But someone who says, as Lawlor summarizes
Taylor, that "knowing what one wants owes to the fact that
self-interpretation … puts in place the very facts known" (p
51), will of course allow that there's cognitive activity associated
with knowing what one wants. Hermeneusis doesn't come for free. The
claim to deny is that the thing known preëxists the knowledge
thereof.) One is free, in particular, to claim that the causal
supposition is a dispensable manner of speaking, that what one
essentially has is, say, a sandy mental irritant around which
reflection and interpretation build up a pearly desire, which was
not the cause of the irritation but the product of the
interpretation. ("What's this grain of sand then" is of course a
good question. But I think on the whole there are lots of advantages
to thinking this way, among them that it can capture the
path-dependence of reflection and satisfaction with its results in a
way that taking the desire as independently constituted can't
obviously do.) And even if we don't go that far, then, on the other
hand, this pattern of inference does not seem like a very reliable
way to go about getting self-knowledge—if our desires don't
cause the internal promptings, then the inference is just structured
wrong.
