In addition to my ongoing work on Kant's ethics, I continue to collaborate with Terry Horgan. A Collection of our essays in metaethics entitled, Moral Twin Earth and Beyond is forthcoming from Oxford University Press. Terry and I are recipients of a John Templeton Foundation Grant that will support our writing a book, Illuminating Reasons: A Essay in Moral Phenomenology during the 2012-2013 academic year.
A selection of papers from the Workshop is published by Oxford University Press.
