The fact that these scientific theories have a fine track record of successful prediction and explanation speaks for itself. (Which is not to say that I don't directly discuss the work of those philosophers who would disagree.) But even if we grant this, many will argue that scientific knowledge in humans, and, indeed, reflective knowledge in general, is quite different in kind from the knowledge we see in other animals.

The great philosophers of the 17th and 18th centuries did not think that epistemological questions floated free of questions about how the mind works. Those philosophers took a stand on all sorts of questions which nowadays we would classify as questions of psychology, and their views about psychological questions shaped their views about epistemology, as well they should have.

I am certainly open to the idea that this might be used to explain other philosophical categories besides knowledge. I have some real sympathy with the work of those moral realists who have tried to give naturalistic accounts of human flourishing, and who offer accounts of right action in such terms. (I suppose this is more evidence that I really do have deep affinities with Aristotle!)

When reflection is thereby demystified, I believe that the temptation to view human knowledge as different in kind from animal knowledge is undermined.

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.

By putting the first-person point of view in a naturalistic perspective, I believe that we may genuinely come to understand it for the first time.

The idea that we should check on our unreflective belief acquisition sounds great, but we need to know whether the processes of reflection which we put to work serves to improve our reliability or not.
