Internalism and Externalism/talk

I don't have any idea which philosophical topic should get top billing on this page. I think the epistemological sense is the newest, and the moral sense is the oldest, and I know very little about the debate in philosophy of mind. The other scale we could use is how popular the terms are in these disciplines, but I have no idea how to determine that information. So, the current arrangement is arbitrary, and if you have a good reason for changing it, go right ahead. MRC
