The kinds of claims I make about knowledge are thus meant to be illustrative of a general argumentative strategy which might well bear fruit in areas of philosophy which I have not thus far explored.

But there is no doubt that my own views on this are, in quite a number of ways, very different from those of Quine.

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.

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 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.

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.

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.
