The psychopathologist has had the great advantage of seeing many trends of the personality which are normally subordinated to other trends when they have escaped from control and achieved Gargantuan proportions. The clinical caricature throws into imposing relief the constituent tendencies which make up the functioning person, and draws attention to their presence and their processes. “Normality” involves a complicated integration of many tendencies, a flexible capacity to snap from one mood, preoccupation, and overt activity to another as the changing demands of reality require. The pathological mind, if one may indulge in a lame analogy, is like an automobile with its control lever stuck in one gear: the normal mind can shift. One has a queer feeling as one passes around the wards of a hospital for the custody of the more seriously disordered patients that if one could assemble the scattered parts of the mind that one could create at least a single supermind. There in one corner is a melancholic who is stuck in the mood of despondency; in another corner is a manic who is expansive and elated; elsewhere is a man whose self-esteem has achieved cosmic dimensions; in the back wards is a deteriorated mind in perpetual repose. Every conceivable nuance of preoccupation and mood with which we are normally familiar seems to be dissatisfied with its minor rôle in a healthy integration, and intent upon autocratic mastery of the mind. The clinical caricature draws attention as sharply as possible to the components of the healthy mind. So every theory of pathological manifestations must presently become expanded or assimilated into a comprehensive account of human psychology. The gross clinical material reveals the intimate interrelationships between soma and psyche. The patient who suffers from obsessive ideas may find relief from obsession by showing hysterical symptoms; and hysterical symptoms may clear up, only to make way for obsessive symptoms. “Pure pictures” are almost pure theories. The patient who is suffering from a definite organic lesion may complicate his troubles by “worry,” and “worry” may be one of the factors in bringing about a physical disease picture. There is evidence that psychological factors are among those significantly operating in such diseases as common colds, asthma, catarrh, hay fever, hyperthyroidism, gall-bladder trouble, gastro-intestinal ulcers, irregular menstruation, and sexual impotence. Fresh vitality has come into modern psychology from the clinic. The psychopathological approach has gradually vindicated itself as more and more of its conceptions find a permanent place in the vocabulary of psychology and social science. Modern psychopathology is itself a recent development, and undoubtedly the most revolutionary figure is Sigmund Freud.
