I have a new draft paper:

The best we can (expect to) get? Challenges to the classic semantics for deontic modals.
2012. Paper to be presented in a session on Deontic Modals at the Central APA, February 17, 2012.

A somewhat programmatic response to recent challenges to the classic semantics for deontic modals (as brought into linguistics by Kratzer), addressing work by Cariani, Cariani & Kaufmann & Kaufmann, Charlow, Kolodny & MacFarlane, Lassiter, Silk.

As always, comments would be very welcome. You know how to reach me.
