This is novel book. Let us start by making a little apology to Psychoanalysis. It wasn't fair to jeer at the psychoanalytic unconscious; or perhaps it was fair to jeer at the psychoanalytic unconscious, which is truly a negative quantity and an unpleasant menagerie. What was really not fair was to jeer at Psychoanalysis as if Freud had invented and described nothing but an unconscious, in all his theory. The unconscious is not, of course, the clue to the Freudian theory. The real clue is sex. A sexual motive is to be attributed to all human activity. Now this is going too far. We are bound to admit than an element of sex enters into all human activity. But so does an element of greed, and of many other things. We are bound to admit that into all human relationships, particularly adult human relationships, a large element of sex enters. We are thankful that Freud has insisted on this. We are thankful that Freud pulled us somewhat to earth, out of all our clouds of superfineness. What Freud says is always partly true. And half a loaf is better than no bread.
