Here, as in so many other cases, however, it turns out that a very commonsensical idea looks far less attractive when one examines some of the experimental work which is not available to us from the armchair.

Talk of belief in these animals is not some kind of anthropomorphism. We simply cannot explain the kinds of problem solving and behavioral sophistication some species exhibit without supposing that they have genuine beliefs. But once these ethologists finish making the case for animal belief, they quickly move to talk of animal knowledge as well. What I argue is that this is not a mere façon de parler.

In my view, philosophers have shown a great deal more respect for the first-person point of view than it deserves. There's a lot of empirical work on the various psychological mechanisms by way of which the first-person point of view is produced, and, when we understand this, I believe, we can stop romanticising and mythologising the first-person perspective.

I do think that it is legitimate to talk of goals and functions in nature, and that these things can be made sense of in naturalistic terms. There is nothing at all contrary to naturalism in the idea of goal-directed systems.

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.

For one thing, I think that there are questions which philosophers raise which, although science bears on them, are not typically the central focus of those who work in the sciences. At the same time, I don't have a view of philosophy which marks it out as different in kind from scientific work
