But there is no doubt that my own views on this are, in quite a number of ways, very different from those of Quine.

The great philosophers of the 17th and 18th centuries did not think that epistemological questions floated free of questions about how the mind works. Those philosophers took a stand on all sorts of questions which nowadays we would classify as questions of psychology, and their views about psychological questions shaped their views about epistemology, as well they should have.

There has certainly been a great deal of work addressing the relationship between naturalism and the first-person perspective. Quite a number of philosophers have suggested that there are features of the first-person perspective that naturalism just cannot accommodate, whether it be qualitative character, or consciousness, or simply the ability we have to think of ourselves in a distinctively first-person manner.

So I do, of course, reject much that is central not only to the psychology of Descartes and Kant, but to their epistemology as well. No doubt, the best available theories of today will look primitive in comparison with what we are in a position to understand hundreds of years from now.

Talk of belief in these animals is not some kind of anthropomorphism. We simply cannot explain the kinds of problem solving and behavioral sophistication some species exhibit without supposing that they have genuine beliefs. But once these ethologists finish making the case for animal belief, they quickly move to talk of animal knowledge as well. What I argue is that this is not a mere façon de parler.

But there is no doubt that my own views on this are, in quite a number of ways, very different from those of Quine.

The role of empirical work in informing our philosophical theories, as I see it, is not that it gives us a better view of our folk concepts, but that it gives us a better view of knowledge, and the mind, and so on.
