There is a worry that many have expressed that, on the naturalistic way of approaching philosophical questions, philosophy will somehow be co-opted by science. I'm not much worried about this.

The experimentalists think that we can only get at our concepts by way of empirical investigation, while the armchair philosophers think that we can skip the experiments and figure things out from our armchairs. What they have in common, however, is regarding our concepts as the targets of philosophical theorising, and I just don't think that, in the vast majority of cases, the subject matter of philosophy has our concepts as its target.

When we recognise that reflective processes are no more outside the causal net than unreflective processes, and that they are bound by similar constraints, we may come to understand the nature of reflection for the first time.

One of the goals of scientific theorising is to develop concepts which are adequate to the phenomena under study. In my view, things should work the same way in epistemology. We want to know what knowledge actually amounts to, not what our folk concept of knowledge is, since, just as with our pretheoretical concept of acidity, it might contain all sorts of misunderstandings and leave out all manner of important things.

No one worries terribly much about who the questions belong to, or whether a given contribution is really philosophy or, instead, properly nothing but science. Perhaps another way to put this is that, although I think that knowledge is a natural kind, I don't think that philosophy is.

When I first began studying philosophy, a good deal of what went on in analytic epistemology was focused on addressing the Gettier problem. At first, I became quite caught up in it, and the kind of analytical ingenuity required for the work appealed to me. After a while, however, I started to lose interest.

What we need to do, however, is figure out what our best available theories of the mind suggest about epistemological issues, while we recognise that we may need to change our views on these questions as new evidence comes in.
