Here’s a nice brief memorial to Hilary Putnam by Roderick Long, with a bonus link to Roderick’s review of Putnam’s Collapse of the Fact/Value Dichotomy and Other Essays, from Reason Papers 28 (2006). Roderick has a real gift for writing these RIP notices, emphasizing the deceased’s achievements but not ignoring what might legitimately be criticized.
Jane O’Grady in London’s Guardian.
The official notice from Harvard, with a link that goes to Putnam’s blog, Sardonic Comment.
Though it’s not online, I’ve always found the interview of Putnam in Giovanna Borradori’s The American Philosopher candid and interesting.
Feel free to add any particularly good ones in the combox.
