I believe, that empirically informed approaches to the question have issued in more illuminating answers than the old armchair approaches. But I think that it would be a terrible mistake to give up on addressing normative questions in epistemology.

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.

I argue is that philosophers have had a tendency to present a kind of mystical view of the powers of reflection. Unreflective belief acquisition is seen in mechanistic terms, but when philosophers talk about reflection, it is as if reflective processes are not bound by the kinds of limitations which inevitably arise from being embedded within the same causal structure which governs unreflective belief acquisition.

It's not just that there is a cooperative spirit of investigation there, where we all recognise that we are engaged in a common project of inquiry. It's also that the philosophers are well-versed in the relevant empirical data, and the scientists are well-versed in the more abstract issues which are typically the central focus of philosophical work.

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.

I was often asked how one could even make sense of this. Isn't the category of knowledge something that we project upon the world, rather than something that we discover in it?

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.
