I am interested in everything.  Time allows me to write on collective intentions (with Sara Rachel Chant), genomics, the evidential status of moral intuitions, and sentential logics lacking the finite model property.

These are some of my papers, including those that are either in progress, under review, or forthcoming.  When a paper has been published, I have posted only the penultimate version.  For a list of everything, see my curriculum vita.

One hour of research
I also occasionally write little, informal things.  There are two here.  The first is a small rant on the neurological misadventures of my life; the second is a reflection on the obvious nudity of our emperor.Papers_files/mental.pdfPapers_files/emperor-1.pdfshapeimage_6_link_0shapeimage_6_link_1
