This book can lay no claim to unity of theme, since its subjects range from skyscrapers to symbols and soul states; but the author claims for it nevertheless a unity of point of view, and one (correct or not) so comprehensive as to include in one synthesis every subject dealt with. For according to that point of view, a skyscraper is only a symbol-and of what? A condition of consciousness, that is, a state of the soul. Democracy even, we are beginning to discover, is a condition of consciousness too.
