Anthony M. Matteo’s “In Defense of Moral Realism” offers a fascinating argument. He begins with the seemingly innocuous premise that philosophy, and by extension theorizing of any stripe, should be linked to what people actually do. Philosophy of science is his analogue, the obtuse, jargon-laden pages of such work often seeming to generate little useful insight for the practitioners of science. An account of morality, by analogy, should be useful to practicing moral agents.
