My own reasons for favouring talk of natural kinds is just that I believe the best accounts of the success of scientific theories presupposes the existence of natural kinds.

I don't know whether I can say that having a career in philosophy has turned out as I imagined, since in many ways I had little idea of what such a life would be like. But philosophy is still tremendously exciting to me, and the opportunity to think, and talk, and write about these issues has been wonderful.

I am certainly open to the idea that this might be used to explain other philosophical categories besides knowledge. I have some real sympathy with the work of those moral realists who have tried to give naturalistic accounts of human flourishing, and who offer accounts of right action in such terms. (I suppose this is more evidence that I really do have deep affinities with Aristotle!)

Internalist approaches to epistemology, I believe, have a great deal of intuitive appeal. Internalists believe that the features in virtue of which a belief is justified must somehow be internal to the agent. On some views, this amounts to the claim that these features must be accessible to introspection and armchair reflection. On others, it amounts only to the claim that they must be mental features.

By putting the first-person point of view in a naturalistic perspective, I believe that we may genuinely come to understand it for the first time.

It started becoming clear to me how one might have views about the nature of mind and of knowledge which are empirically informed. This way of thinking about philosophical theorizing makes sense of how philosophy might be a legitimate intellectual activity, in a way that a good deal of the armchair philosophy, I believe, cannot.

Bealer has a number of reasons for thinking that a naturalistic epistemology is self-undermining. Let me focus on one of these. (I've tried to take on all of them in the first chapter of Knowledge and Its Place in Nature.)
