Does Perceiving Require a Perception of a Perception?

Posted on by

Since we perceive that we are seeing and hearing, it is necessary that one perceives that one sees either by sight or by some other sense…Further, if the sense which perceived sight were to be other than sight, then either this will carry on into infinity or there will be some sense which will be of itself, with the result that one should grant this in the case of the first sense (De Anima, 425b22 ff., trans. Shields).

In the De Anima passage above Aristotle tells us that there are no perceptions of perceptions, that is, a perception as such does not need to appeal to yet another perception to explain our awareness of it.  Rather the capacity of perception itself, when active, carries with it the awareness of its own perception.  Aristotle’s main problem with multiplying perceptions here is that this will lead to perceptions of perceptions of perceptions, a never-ending cascade of perceptual regress, if you will. 

There would seem to be at least two other difficulties Aristotle would wish to avoid with “perceptions of perception.”(1)  The first is that the second perception would not be “of” the object of perception, the purported intention of the thought.  Rather it would be of the first perception (even if this included the original object as well), relegating the first perception to a role not unlike the one played by the Forms in Plato’s epistemology.  That is, the first perception would be the noetic stuff given to the awareness, just as the Forms are ultimately that by which and of which a thought is about.  On this understanding the first perception would be of the object, while the second perception would be of the perception of the object.  Consciousness is thus directly removed from the true object of its intention, and there is an awareness not of something out there in the world, but at a remove of one step from that world.  If this is so, it is easy to see why Aristotle would avoid this difficulty by positing that a perception, or a thought, carries with it its own awareness. 

The second difficulty for “perceptions of perception” is that the two perceptions are presumably identical.  And either they are precisely identical, in which case one of them is superfluous, or they differ only in that the second is the perception of the first, while the first is of some other object.  In this second case then, the second perception perceives the first perception with the result that there is an awareness of either the first perception or the object of the first perception, it is unclear to say which.  Whichever the object of the second perception though, it would seem better served, since we have already granted that a perception qua mere perception (in the second perception) has the capacity to serve as an awareness, that we grant this same power to the first perception, eliminating what appears to be an unneeded appeal to the unsure grounds of infinite regress.

This impulse to put “safeguards” in place for capacities seems to be a mainstay in philosophy: for every capacity there must be some further capacity over and above this one in order to ensure proper functioning of the capacity.  John McDowell criticizes this maneuver lucidly when he says, “Some people have a capacity to throw a basketball through the hoop from the free-throw line. Any instantiation of such a capacity is imperfect; even the best players do not make all their free throws” (McDowell 245).  Thus, to make a basket with (a given) regularity belongs to the capacity itself, not by a capacity over and above the ability to hit a free throw.

What is the “Nature” of the Philosopher in the Republic?

Posted on by

In Book VI of the Republic a grocery list of the desirable traits to be found in a philosopher are described by Socrates.  The list of virtues is long and encompassing: a love of learning of things that are (485b), no taste for falsehood (485c), a concern with the pleasures of the soul, not the body (485d), being moderate and not a lover of money (485e), not given to petty speech (smikrologia) (486a), believing that death is no great evil (486b), being “just and tame not hard to get along with and savage” (486b), learning easily (486c), has a good memory (486c), has measure and charm (486d).

Equally prominent in this discussion of what the virtues are is the continual emphasis that  Socrates places on nature.  We are left to puzzle about what the definition of “nature” is here, a term frequently and problematically employed in philosophical contexts.  The traits listed above are somehow desirable in the philosopher only if they are present by nature.  However, there is little discussion of what nature is, and what we are left with is a view of nature that consists in little more than whatever inborn proclivities one happens to have, as is exemplified in this statement about a man erotic by nature, “It’s not only likely, my friend, but also entirely necessary that a man who is by nature erotically disposed toward someone care for everything related and akin to his boy” (485c). 

This explanation of nature is further corroborated by the foreshadowing of the philosopher first seen in Book II.  There, Socrates and Glaucon agreed that they were looking for a chimerical kind of guardian, one who is, “at the same time gentle and great-spirited.  Surely a gentle nature is opposed to a spirited one”  (375c).  When they deliberate further upon this discovery, Socrates and Glaucon despair, since the combination of two opposed traits would appear to be a contradiction.  However, soon Socrates realizes that, “You know, of course, that by nature the disposition of noble dogs is to be as gentle as can be with their familiars and people they know and the opposite with those they don’t know”  (373d).  The explication of this “noble dog,” analogous to the philosopher, is telling, because it will inform us not only about Plato’s conception of nature here, but by extension the nature of the philosopher.  Socrates explanation of the dog’s behavior is not in terms of training, but something rather more inborn: “When it sees someone it doesn’t know, it’s angry, although it never had any bad experience with him.  And when it sees someone it knows, it greets him warmly, even if it never had a good experience with him”  (376a).  Thus it is not by training that the dog has learned to embody a composite of two opposed traits, for this would be impossible.  Furthermore, as Socrates analysis makes clear, the dog’s nature makes it immune to any training by experience which it could have undergone.  It is friendly to its owner by nature, and hateful to strangers by nature despite any exposure intentional or unintentional which could train the dog to behave in exactly the opposite way.  Thus when we are told that the philosopher is to hold certain traits by nature, this is to say that he should be possessed of these traits from birth, which manifest themselves in a disposition that easily expresses them.

If Images are Inferior, Why is the Allegory of the Cave an Image?

Posted on by

The Platonic vocabulary is often skeptical and even antagonistic toward the uses of images.  This denigration is attributed to the mutability of images, so that we could really apply this criticism to anything that changes, which would apply to all of the visible world.  Among many other places in the Republic, Socrates makes the distinction clear by explaining how what we think about determines the very certainty of that thought:   

Well then, consider that the truth of the soul is thus: Whenever truth and what is shine upon something, the mind attaches to this, it intellects and knows and appears to have intelligence.  But whenever it attaches to that which is mixed with obscurity, that which comes to be and passes away, it has opinions and sees dimly, changing opinions here and there, and seems not to have intelligence (Republic 508d3-8). (1)

These two sides of opinion and knowledge, perishability and persistence, are, as Socrates will shortly explain, the sensible and intelligible realms.  Socrates says there are two kinds of objects of the sensible realm, shadows, appearances and reflections, but then also those things of which these are the shadows, appearances and reflections.  It is obvious that these mere reflections are inferior to the objects which they represent: animals, people, etc.  It goes without saying, moreover, that everything in the sensible realm is inferior to anything in the intelligible realm.

Now here is the part I take particular interest in.  Socrates says that all of the shadows, appearances and reflections in the sensible realm are images (τὰς εἰκόνας) of other things in the sensible realm.  Because of this, they obviously have the least substantive mode of existence, and along with this, the lowest level of cognitive certainty.  Yet image-language is precisely what Socrates employs, and is his own self-characterization of what he does, in the allegory of the cave.  He tells us at the beginning of Book VII, as he is about to explain the cave allegory, “make an image [ἀπείκασον] of our nature in such a condition concerning education and lack of education” (514a1-2). (2) (3)

The question arises then, why are we using an image to describe a program of education the goal of which is to lead one away from images?  This is especially curious because it comes right before Socrates exposition of philosophical education, beginning with arithmetic.  Perhaps the allegory of the cave is a necessary propaedeutic before one begins— not to undertake such an education— but to even understand its purport and goal.  Or perhaps because the uninitiated reader has not yet taken the first step to a philosophical education, he must be accommodated where he is at, in this case at the lowly level of understanding mere images, so that he can be taken where he needs to go.
