I write primarily on Wittgenstein, Cavell, and topics in aesthetics (improvisation, music, film). I am contributing co-editor (with Victor J. Krebs) of a volume on Wittgenstein's aspect-seeing remarks, Seeing Wittgenstein Anew (Cambridge UP, 2010). Other publications include articles and book chapters on Emerson, the Neo-Confucian thinker Wang Yangming, and moral perfectionism.
