Aristotle's Ethics

i sort of liked the answer you gave me about responding to calicles and thrasimachus. Maybe the idea is, well, if you pushed him on the theoretical underpennings of his ethics, he would have something to say. But i think we should also bear in mind that what aristotle in the ethics might have thought didn't need too much argument. For instance, he doesn't argue very hard for the claim that human beings have a natural function that we might question. Now anyone wanting to revive aristotelian philosophy would have to work a lot harder so that they would have good reason,. even good practical reason, to refer in their ethics to metaphysics.
