The upshot of the evidence, then, is about as follows: Psychoanalysis has extended in important ways our knowledge of the ramifications of the sex impulses and of the impulse to egoistic dominance; it has increased our knowledge of the motivation of much that mistakenly, through “rationalization,” offers itself as reasonable conduct; it has put us upon our guard against a considerable range of self-deceptions; but it has not proved the actual existence of the diabolism that is pictured in “the Unconscious.” And let it be remembered that, in front of the patient whose mind is supposed to be a den of wild beasts, sits the psychoanalyst himself, a self-controlled, benevolent, and high-minded man. Over against the theoretical Unconscious let us place the certainly actual honor of the psychiatrist in his handling of his patient--scrupulous honor in a situation that brings to the fore the most enticing emotions and impulses. A word should be said concerning the bearing of intelligence-tests upon our knowledge of the motives of men. There is a popular tendency, which is not altogether absent from academic circles, to jump at conclusions concerning motivation from the results of experiments upon something else. The adjectives “superior” and “inferior,” applied primarily to levels of intelligence, come almost insensibly to be a designation of levels of manhood or of decency in general. Now, the most that can be said as yet concerning the interrelations between the various desirable and undesirable factors of personal make-up is that, on the whole, the more desirable tend to bunch together, and the undesirable likewise tend to go in bunches. It cannot be said, however, that there is only one worthwhile type, and that the core of this type is superior intelligence. We do not yet know just what this “intelligence” that we have been measuring is, nor what it guarantees at its various levels. It is certain that achievement depends upon other qualities also, so that failure may attend a high IQ, and success may be won by steady and persistent employment of an intelligence distinctly lower. Wisdom and goodness and efficiency have other foundations in addition to some as yet undetermined degree of intelligence. Further, it appears that within the general concept, “intelligence,” we are required to distinguish between types. There is, for example, in addition to the abstract or conceptual type that is most cultivated in schools, a mechanical type of intelligence, very likely there is a social intelligence, and there may be others. We do not yet know, except in the vaguest way, how these varieties of intelligence are dynamically related to the requirements of wise living, either individual or social.
