Arthur John Terence Dibben Wisdom (12 September 1904, Leyton, Essex – 9 December 1993, Cambridge), usually cited as John Wisdom, was a leading British philosopher considered to be an ordinary languagephilosopher, a philosopher of mind and a metaphysician. He was influenced by G.E. Moore, Ludwig Wittgensteinand Sigmund Freud, and in turn explained and extended their work.
He is not to be confused with the philosopher John Oulton Wisdom (1908–1993), his cousin, who shared his interest in psychoanalysis. - Wikipedia
This guy is a very impressive thinker, at least as represented by the essays in this book. Makes me want to revisit my G. E. Moore books and give them a second chance...
