Philosophizing - professionally
Today begins five days of rubbing heads with people who hopefully think like I do - or at least, they think about the things I think about. My first strictly academic philosophy conference. And a whole session on (what I consider to be) one of the great outstanding questions for both philosophers of biology and biologists - particularly paleobiologist: the (disputed) existence of levels of selection, which employs concepts, definitions, and assumptions about evolutionary trees and the nature of species. Very, very cool. Answering this question is on my 10-year to-do list.
