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.

I have made some headway in addressing these questions, however, and succeeded in explaining how it is that the category of knowledge might play an important role in empirical theories. To the extent that talk of knowledge can be shown to play an explanatory role in such theories, the analogy I wish to make with paradigm natural kinds such as acids and aluminum starts to make a good deal of sense. This is, of course, connected with the issue of the role of intuitions in philosophy.

The kind of approach I take is different from much of experimental philosophy. Although the experimental philosophers and I are certainly in agreement about the relevance of empirical work to philosophy, a good deal of their work is devoted to understanding features of our folk concepts, and in this respect, at least, I see them as making the same mistake as those armchair philosophers who are interested in conceptual analysis.

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.

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.

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.

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.
