Matthew Lutz is an associate professor of philosophy at Wuhan University in Wuhan, China. His research interests are in Ethics and Epistemology, with a particular interest in moral epistemology. His dissertation is on moral skepticism, wherein he argues that moral knowledge is impossible for moral non-naturalists. Lutz has a number of continuing projects. Within moral epistemology, he is interested in evolutionary debunking arguments, moral disagreement, and the question of whether moral naturalism can avoid epistemic issues. Within metaethics more broadly, he is interested in moral supervenience, the nature of our moral concepts, and moral error theory. And within epistemology more broadly, he is interested in the nature of justification and how justification relates to knowledge, whether the Gettier problem can be solved, the prospects for a causal theory of knowledge (better than one might think!), and how pragmatic considerations relate to knowledge attributions.
