Ludwig Wittgenstein, who died in Cambridge in 1951, is one of the most powerful influences on contemporary philosophy, yet he shunned publicity and was essentially a private man. His friend Norman Malcolm (himself an eminent philosopher) wrote this remarkably vivid personal memoir of Wittgenstein, which was published in 1958 and was immediately recognized as a moving and truthful portrait of this gifted, difficult man.

This edition includes also the complete text of the fifty-seven letters which Wittgenstein wrote to Malcolm over a period of eleven years. Apart from the quotations in the Memoir these letters are previously unpublished. They reveal how much friendships mattered to Wittgenstein, and how concerned he was for the health and well-being of his friends. His human qualities become evident; he advises, warns, jokes. and is grateful and affectionate.

The volume also features a concise biographical sketch by another leading philosopher who was a friend of Wittgenstein, Georg Henrik von Wright.

Much has been published about Wittgenstein since his death, but nothing brings us closer to the man himself than this modest classic of philosophical biography.
