"The portrait that emerges from this account is human, all too human, but the author's respect for Wittgenstein is never in doubt. Though brief and written so that it can be understood by those with no previous knowledge of Wittgenstein's philosophy, this book is an important contribution to our understanding of the man and of the development of his thought." —Walter Kaufmann
