Professor Cartwright, longtime member of the philosophy faculty at MIT (where he was professor emeritus), passed away on December 19.  I will link to memorial notices as they appear.

UPDATE:  MIT has posted Judith Jarvis Thomson's admiring remarks on Cartwright for a festschrift published for him a number of years ago.  They are both evocative and sociologically instructive about a certain conception of philosophy.  Alex Byrne tells me a memorial notice will be forthcoming shortly.

ADDENDUM:  There is now a memorial notice and a link to a Facebook appreciation page at the same link, above.
