This is Peter Strawson, Oxford's Waynflete Professor of Metaphysical Philosophy from 1968 to 1986. One of his many contributions to philosophy is a delightful little whimsy. He called it his First XI. The idea is that of all the Great Dead Colleagues, eleven men stand head and shoulders above the others. And the game is to identify them.
Of course, everyone has their own list of favourites. I would like to include The Buddha, Newton, Nietzsche, Darwin. Great and influential thinkers all. But the rules are strict. You are not allowed to select anyone, no matter how important a thinker, no matter how great his intellectual contribution to human thought, who did not practice the art of philosophy in the way that we, the present academy, do. He has to be recognisably one of us.
See if you can guess them all. There are two Greeks, three Germans, two Englishmen, one Scotsman, one Frenchman, an Austrian and an Italian. And if and when you get stuck, the answers are here.
