The author, in attempting to nourish his mind at the feast of reason, appears to have nibbled at everything, swallowed much and digested nothing. His thesis is a nebulous idea that there is "a subtle rôle played by ideas through suggestion" which will some day solve all problems, from medical through economic, and many more. The reader gets nothing from the book but a jumble of words. Such ideas as it contains are the ideas of others, usually quoted in connections in which they scarcely apply. The book is not worth the time it takes to read it.
