(maybe that would have been a better example than a scintillating scotoma). — jamalrob
I think, in the case of the scintillating scotoma, or an after-image or color patch, that a
de re reading is also intelligible. That is, since you only refer to the object seen
qua visual impression, I think it can be true to say 'there is an x such that x is an after-image and I see x.' I don't think objects in the wide sense have to be 'located' anywhere in particular, and it's perfectly fine to treat things in the visual field as objects and talk about them that way. That is not the same as seeing a face in the clouds: when someone says this, they're not committed to there being any face at all, except metaphorically; but I think you are in some sense committed to saying
there is an after-image (look, it's right there). The after-image and scintillating scotoma are not
supposed to be extra-visual objects in the first place, like a face is.
I see no reason, other than philosophical prejudice, not to say the same about splotches of color and so on in every case. Here, of course, you often do have to take a sort of abstract and artificial view of your own perception to say something like 'I see a red patch of color' and mean it, but that's fine, there's no reason to rule it out on that account. Day to day though, I would say people don't do this sort of thing very often -- it usually happens when something's wrong with your eyes or you for some reason are relaxed and curious, and want to take an objective distance toward your own experience.
It is this distinction that I am claiming is missed by the indirect realist, who thereby finds that all we ever see is faces in the clouds, where some correspond to real objects and others do not. — jamalrob
I need to clarify a few more things here.
De dicto and
de re readings of these verbs can be distinguished, but that doesn't mean they're mutually exclusive. Suppose again I say 'John is seeking a unicorn.' That can be true
de dicto: he has his 'sights' set on finding some unicorn or other; it can be true
de re: there is some unicorn (say, Charlie), and John is seeking him; it can be true
both: John is seeking Charlie, and since he knows Charlie is a unicorn, he has his sights set on finding a unicorn, too; it can be true
de re but not
de dicto: John is seeking Charlie, but doesn't know Charlie is a unicorn, and so he is seeking an x such that x is a unicorn, but does not have his sights set on finding a unicorn; and it can be true
de dicto but not
de re: John has his sights set on finding a unicorn, but not on any individual in particular (rather he just wants to find some unicorn or other, he doesn't care which).
The reason this is important is because it is possible to see something
de dicto without seeing
anything de re. If I shut my eyes and imagine a house, I can with propriety say on the
de dicto interpretation, 'I see a house.' This can be true, even if
de re there is no x at all such that I see x: I don't see anything in this sense, since my eyes are closed. But the reverse is not true: you cannot see something
de re without seeing something
de dicto. It is true that I might see a church
de re, and not see
a church de dicto: I only see a barn
de dicto. But nevertheless, it is impossible, given that I see something, that I do not see
something de dicto. So in this respect, the indirect realist is perfectly correct. And they are perfectly correct in claiming that it is possible to see 'the same thing' in one sense regardless of whether you are hallucinating or not, and regardless of what the object 'actually' is.
Because the de re sense is privileged (certainly by realists), faces in clouds, hallucinations, and shrinking tables are thoughtlessly taken to be objects of perception rather than in various ways constituting perceptual experiences (in the same way that the pain constitutes a pain experience rather than being an object of awareness in a perceptual sense). — jamalrob
It depends on what you mean by 'objects,' but okay. And certainly phenomenalists like Ayer are far more sophisticated and subtle than this crude criticism would suggest. I also think, as I said, that it is possible in analyzing your own experiences to objectify them and make of them
de re objects. And of course, it's perfectly intelligible to speak of the experiences themselves as such objects.
But I don't think direct realists make that claim. Their point is that the sense in which one sees something shrinking, or sees a face in the clouds, does not permit the indirect realist to say that one always only sees a perceptual intermediary, precisely because, as you say, it does not entail that ‘there is an object such that it was shrinking and I saw it.’ — jamalrob
Okay, yes, I agree with this. But I'm not sure the hypostatization of the sensory intermediary in these cases is really what's crucial about indirect realism insofar as it's a criticism of direct realism. In other words, the fact that the indirect realist's positive thesis is incorrect doesn't really help the direct realist in any way, who will be beset by the same problems.
But what does "mediated" mean here? It all hinges on how one characterizes the fact that we see faces in clouds or hallucinations or mirages: if perception's being mediated means that it has its own properties that can be studied independently of the properties of whatever is perceived, and is perspectival, partial, subject to error, and relative to the perceiver's specific evolved physiology, his cultural milieu, his motivations and affect, and so on--if this is what "mediated" means then the direct realist can happily agree that perception is mediated. — jamalrob
I'm not so sure he can. You may think he can, or want very badly that he can because it would make you more comfortable with the position, but these are not all the same thing. Usually trying to account for mediation leads direct realists into incoherencies that invite dreaming arguments, and so on.
First, I don't think it's true that we are often met with indeterminate impressions. — jamalrob
It doesn't matter how often it happens. That it can happen, period, is a problem for the direct realist. And of course you can
make it happen once you figure out how.
Are there really times when what we see is inchoate and meaningless? — jamalrob
Yes.
But after reading what you say about unconscious inference, I suspect that you have more sympathy with this view than I at first thought: — jamalrob
'Inference' is misleading, in the sense that I think there's no transference from one sort of thing to another. In brief, I do not really think there is such a thing as perception as philosophers talk about it. If you like, direct realism could be an attempt to logically deduce
what qualities perception must have if it is to exist, and it rightly criticizes indirect realism for not sticking to those qualities. But then, since direct realism is internally incoherent, this shows that perception is internally incoherent.
If I had to pick a word, I would say that objects are
projected, not inferred or perceived or anything like that. If I could speak with more liberty, I would simply say, there are no objects. Period. There are experiential movements, some of which settle into more or less regular patterns. There is nothing they are 'about' or 'aim at.' They contain their telicity internally, in pleasure and pain.
So I'll return to the possibility that you mean "inference" metaphorically, to describe what the brain is doing in perception. Does this mean that unconscious brain processes can, like inferences, be mistaken? Does the use of "inference" mean you think there is something analogous to inference carried out by cognitive modules in the language of thought, as in computationalist theories? — jamalrob
It doesn't even matter. Even if we move the goalposts, the fact remains that sometimes you do literally infer what you are perceiving consciously, as when trying to figure out what a certain smell is. That in most cases the process isn't a conscious one seems to me metaphysically irrelevant. You have a lot of work to do in order to see anything. Sometimes it's conscious work, sometimes not -- so what?
As might now be clear, I didn't mean passive in the Cartesian or Kantian sense, as opposed to the active synthesizing of the manifold by the understanding. I meant it in Gibson's or Merleau-Ponty's sense, as opposed to the constant probing movements of a perceiver in an environment, relative to its affordances for action. Indirect realists imagine a passive sensory receptivity borne by a single static eye, the stimuli from which are only then worked up into perception by an active cognition--because for the indirect realist, the perceiver as bodily subject or situated organism is passive, its only relevant positive activity taking place behind the veil and in the head. — jamalrob
Honestly, I don't see how an indirect realist in any way, shape or form is less able than a direct realist to talk about, account for, or ascribe importance to active understanding and affordance in this way. I suspect this is more of a vague feeling of the 'character' of the positions that doesn't amount to much.
You say that the "remove"--the separation of mind and world or subject and object of perception--becomes apparent when perception breaks down. I would say rather that there is only such a remove when perception breaks down (or in "snapping out", etc.). — jamalrob
There are two theses held by the direct realist, both of which I think are wrong. These are that experience is:
1) teleological, aims naturally at something outside of it, and sometimes fails to hit its target;
2) normative, has a 'job to do,' and so sometimes can 'fail at it.' Furthermore, there are 'right' and 'wrong' ways to perceive (there must be, since there is a way the world is, and a way it's presented, and since these are separate, the latter is good only insofar as it somehow hooks up with the former)
We can talk about why I think these are both wrong, and why so much of the mistaken realist metaphysics depends on them; but I just wanted to say that this is where your 'snapping out of it' language comes from, and the only background against which it makes sense. I suspect what is at work is taking certain phenomenological or practical qualities of experience and mistaking those qualities for metaphysical ones -- that because, for example, some perception is felicitous or useful, it therefore is not just that, but further 'real' (insert some story about how there are evolutionary pressure to make perception 'good,' and so on).
That, of course, is more deeply Cartesian than anything you criticize.
