A longtime professor at the University of Turin, where he was emeritus, Professor Vattimo was a leading exponent and defender of "postmodern" philosophy in Italy and in Europe, although somewhat less-known in the Anglosphere. There is an obituary in Italian here. Comments are open for remembrances from those who knew Professor Vattimo, or from those who wish to comment on the significance of his work.
(Thanks to Mattia Riccardi for the pointer.)
