* A long lost letter by Descartes has been found; it's to Mersenne and discusses the publication of the Meditations. You can find more details at the website of Erik Jan-Bos, the discoverer.

* A good post by Paul Gowder on a common error about shared responsibility.
* Dog jousts rabbit. Poor rabbit.
* Burying the dead in Haiti. Burying the dead is one of the traditional corporal works of mercy.
