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.
Hilary KornblithThe 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.
Hilary KornblithExternalists reject any such view. I think that the idea that we can tell, simply by way of reflection, whether our beliefs are justified, is deeply commonsensical. More than that, the idea that responsible epistemic agents ought to reflect on their beliefs, and hold them only if they somehow pass muster, is utterly natural.
Hilary KornblithBut there is no doubt that my own views on this are, in quite a number of ways, very different from those of Quine.
Hilary KornblithI 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.
Hilary KornblithEpistemologists should be concerned with knowledge and justification and so on, not our concepts of them; philosophers of mind should be concerned with various features of our mental life and the large-scale structure of the mind, not our concepts of mind, or consciousness, or anything else
