A misleading title, for this is another sally into the field of self-discovery, dealing with various aspects of the personality and not just the love-hate apparatus. Again the statistician of human personality par excellence supplies tests and more tests to determine one's own tendencies, -- memory distinctions, sensory endowments, objectivity or subjectivity, whether introvert or extravert, the role of the will and the imagination, the emotions. He uses four emotional components in combination the one with the other, in greater or lesser degree, -- fear, wonder, sex and rage. His psychological bases are sound -- his formulae for self-catechising may be dangerous, and are inevitably superficial. But they are popular.
