I just learned that Denis Dutton has died at only 66. Others knew him as a professor of philosophy or media commentator; to me he was the guy who ran the website Arts & Letters Daily, which I read every day (and occasionally corresponded with him about) back around the turn of the millennium and sporadically in the years since—it was always thought-provoking, but there was just too much else to read. If I knew that he was a native Californian, I’d forgotten it; he got his PhD in philosophy from the University of California Santa Barbara in 1975, so I might have passed him on the street when I was visiting my parents in that lovely city all those years ago. Since 1984 he’s been teaching at the University of Canterbury in New Zealand. His voracious and wide-ranging interest in ideas and his enthusiasm for sharing them will be greatly missed.
