The fact that we have been able to develop a successful science, which issues in ever more accurate predictions and broader explanations, is the real ground for confidence that we are in a position to gain knowledge of the world around us. At the same time, one might ask how it is that the cognitive equipment we have came about, and here, no doubt, our evolutionary origins are relevant.

In my view, since the case can be made that knowledge too is a natural kind, the role of pretheoretical intuitions is similarly diminished in epistemology.

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.

Here, as in so many other cases, however, it turns out that a very commonsensical idea looks far less attractive when one examines some of the experimental work which is not available to us from the armchair.

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.

I largely defer to the cognitive ethologists. I believe that the arguments that they make on this score are extremely persuasive. More than this, I do think as well that a priori objections by philosophers to successful research programs in the sciences have a very bad track record.
