"The authors of this entertaining book vividly re-create the context to this sorry tale. They show us the stresses of being a Wittgenstein and a Popper, coming from very different social backgrounds in the hothouse city of Vienna. And they do an excellent job of reconstructing the philosophical differences, and the passions rightly aroused by the seemingly innocuous choice between problems and puzzles. They even manage to be fair to both parties, which is more than either party was to anybody else."Edmonds, David is the author of 'Wittgenstein's Poker The Story of a Ten-Minute Argument Between Two Great Philosophers', published 2002 under ISBN 9780060936648 and ISBN 0060936649.
