The ruminations and vituperations of Mr. Wylie- previously directed in Generation of Vipers at the American mother, this time largely directed at organised religion. This ""science of philosophy"", or inquiry into the modern theory of instinct, is in part an interpretation of Freud and Jung, starts with an acceptance of the fact that man is an animal. He goes on to show the pattern of the ego, its instincts of vanity and acquisition, its fear of death. The latter part goes somewhat afield of the intention of the book, attacks with robust rhetoric the church, ""school for hypocrites and university of ignorance"" in all its ""moribund architecture""... Once again the ardor, the impunity, which gave his previous books a certain thundercloud excitement; but also once again there is little restraint of reasoning, little impartial intellect, and a certain sensationalism.
