I just learned from R.P. Wolff's blog that the philosopher Arthur Danto has died. I sometimes read his art criticism in the days when I subscribed to The Nation. Also, at least one person I know quite well had some interaction with him. (The five million *cough* daily readers of this blog will be used to cryptic statements of this sort by now.)
Btw it seems to me that an unusually large number of well-known scholars have passed on lately, but I don't see much point in listing them here.
P.s. I mentioned Danto here.
