"Searching, scholarly and thoughtful, this valuable book is essential reading. It is not only for psychoanalysts but for all concerned people. The possibility that an innate principle of self-annihilation is at work in human behaviour and at the level of the species as well as at that of individuals is disturbing. Yet much in our contemporary situation points in its direction. If we do not want to know more, we may destroy ourselves, and many other species besides. But if we understand more, it can be ameliorated."-David Taylor, Hon,.
