O’Brien and Koons on metaphysics and morality

Over at Public Discourse, philosophers Matthew O’Brien and Robert Koons have posted a three-part series on metaphysics and morality: “What Does it Mean to be a ‘Political Animal’?”; “Moral Absolutes and the Humpty Dumpty Fallacy”; and “Who’s Afraid of Metaphysics?”  Give ‘em a read.  (By the way, if you haven’t seen The Waning of Materialism, an important recent anthology edited by Koons and George Bealer, you should check that out too.)
