Aristotle is famous for thinking that all our knowledge comes from perception. But it's not immediately clear what this view is meant to entail. It's not clear, for instance, what perception is supposed to contribute to the more advanced forms of knowledge that derive from it. Nor is it clear how we should understand the nature of its contribution—what it might mean to say that these more advanced forms of knowledge are "derived from" or "based on" what we perceive. Aristotle (...) is often thought to have disappointingly little to say on these matters. I argue here that this thought is mistaken: a coherent and philosophically attractive view of perceptual knowledge can be found in the various texts in which Aristotle discusses perception's role in animal life, the cognitive resources on which it does and does not depend, and the relation it bears to practical and theoretical modes of understanding. This book offers a sustained examination of these discussions and their epistemological, psychological, and ethical implications. It defends an interpretation of Aristotle as a moderate sort of empiricist, who thinks that we can develop sophisticated forms of knowledge by broadly perceptual means—and that we therefore share an important part of our cognitive lives with nonrational animals—but also holds that our intellectual powers allow us to surpass these animals in certain ways and thereby develop distinctively human forms of understanding.

The argument at Phaedo 74 B 4‐C 6 that the equal itself is ‘something different from’ sets of physical equals depends on Leibniz's Law: there is a property that perceptible equals have that the equal itself does not have. What I call the ‘epistemic interpretation’ holds that the property is an epistemic one: having appeared unequal. The ‘ontological interpretation’ holds that the property is not epistemic, but simply the property of being unequal. The most natural reading of the text favours (...) the epistemic interpretation; scholarly support for the ontological interpretation is based on the widely held view that on the epistemic interpretation the argument is manifestly invalid. But this view implicitly relies on an impoverished sense of ‘appearing’ as equivalent to ‘being thought’. Drawing on an analogy with colour perception, I elaborate an experiential sense of ‘appearing’ which makes Plato's argument on the epistemic interpretation philosophically defensible. (shrink)

Interpretations of recollection in the "Phaedo" are divided between ordinary interpretations, on which recollection explains a kind of learning accomplished by all, and sophisticated interpretations, which restrict recollection to philosophers. A sophisticated interpretation is supported by the prominence of philosophical understanding and reflection in the argument. Recollection is supposed to explain the advanced understanding displayed by Socrates and Simmias (74b2-4). Furthermore, it seems to be a necessary condition on recollection that one who recollects also perform a comparison of sensible particulars (...) to Forms (74a5-7). I provide a new ordinary interpretation which explains these features of the argument. First, we must clearly distinguish the philosophical reflection which constitutes the argument for the Theory of Recollection from the ordinary learning which is its subject. The comparison of sensibles to Forms is the reasoning by which we see, as philosophers, that we must recollect. At the same time, we must also appreciate the continuity of ordinary and philosophical learning. Plato wants to explain the capacity for ordinary discourse, but with an eye to its role as the origin of philosophical reflection and learning. In the "Phaedo", recollection has ordinary learning as its immediate explanandum, and philosophical learning as its ultimate explanandum. (shrink)

In the _Phaedo Socrates says that as a young man he thought it a great thing to know the causes of things; but finding existing accounts unsatisfying, he fell back on a method of his own, hypothesizing that Forms are causes. I argue that part of what this hypothesis says is that certain phenomena--the ones for which it postulates Forms as causes--are the result of processes whose object was to produce them. I then use this conclusion to explain how Socrates' (...) discussion of causality in the _Phaedo might be supposed to contribute to his final argument for immortality. (shrink)

This paper concerns Plato’s characterization of the body as the soul’s tool. I take perception as an example of the body’s usefulness. I explore the Timaeus’ view that perception provides us with models of orderliness. Then, I argue that perception of confusing sensible objects is necessary for our cognitive development too. Lastly, I consider the instrumentality relationship more generally and its place in Plato’s teleological worldview.
