This is why RPW’s blog is the best on the Internet. In the comments to an entertaining start to debunking the shibboleth that a rising educational tide lifts all boats is a superb history of the early development of formal modal logic by a graduate student in philosophy. Wolff – always game for a digression, and who happened to have been a present, alert observer of the scene during the historical period under discussion – peppers the narrative with stories of the time. Plus there are pinches of snark and academic territorialism.
It is really excellent stuff.
