Talks with a Devil
by P.D. Ouspensky
Introduced and edited by J. G. Bennett. The two stories in this book, "The Inventor" and "The Benevolent Devil," were written just before Ouspensky met Gurdjieff and just after he had returned from the East, "in search of the miraculous." They examine the whole question of conscious evil and the view that humanity's chief error is believing that the material world is the only reality.
