The distinguished political philosopher Thomas Pogge, who has spent the past couple of years at the Center for Applied Philosophy & Public Ethics at the Australian National University, will be leaving the Department of Philosophy at Columbia University for the Department of Political Science there, as of this fall.  (He will be back at CAPPE in 2007-08, then returning to Columbia Poli Sci thereafter.)  Together with the loss of Jeremy Waldron (an affiliated member of Philosophy) to NYU, this is a significant blow to political philosophy in the Philosophy Department.
