This question is asked out of a relative ignorance of "analytic" or "Anglo-American" proceedings, so broad, simplified answers are quite welcome.
A slew of terms may be used to characterize the approaches of individual philosophers as, say, realists, cognitivists, constructivists, naturalists, evolutionary epistemologists, and so forth. Stances with respect to reductionism, AI, metaphysics, relativism, skepticism, and also "fence in" various debates.
Can the field today be roughly divided into broad, contending positions? Perhaps ten or so. I do not mean topics or areas of study, but arguments and beliefs that are typically incompatible and can be identified by commonly used terms.... somewhat in the manner of Bacon or Kant's rough division of "rationalists" and "empiricists."
I'm looking for the sort of overview of contemporary positions that is hard to sift out of indexes or sources like SEP.... and, it must be added, that individual philosophers themselves are usually quick to deny.
