(1) THERE has been a rapid growth of interest, during recent years, in the theoretical explanation and practical treatment of mental diseases, especially of those so-called “borderland” cases between the normal and the definitely insane. The problems involved have aroused vigorous controversy, and the most conflicting views have been put forward by different schools of thought. Among the exponents of these various doctrines two of the most distinguished are Prof. Freud, of Vienna, and Prof. Morton Prince, o£ America. Broadly stated, Freud's psychological system is based upon a fundamental distinction between two classes of memories and mental tendencies, viz., ordinary memories and tendencies and those that have for one reason or another been repressed. The latter are those involved in mental conflicts and accompanied by pain. They constitute the true “unconscious” of the mind. The other memories are classed by Freud as “pre-conscious.” Unconscious memories and mental tendencies retain their original intensity, and although outside of consciousness continue to act, and from time to time affect consciousness. “Like the shades in the Odyssey,” says Freud, “they come to life again as soon as they have drunk blood.” When especially intense, or when the repressing power of the mind is in one way or another diminished, they may produce the symptoms of hysteria and of other forms of mental disease. But they are also the cause of dreams in normal persons, and of the apparently unintentional mistakes in speech, writing, and other actions, to which we are all more or less subject when our attention is distracted. Freud tries to sustain this latter view in his “Psychopathology of Everyday Life.” He contends that the method of psychoanalysis,1 or free association, demonstrates conclusively that such slips of memory, speech, and writing are really intentional, and due to the concomitant working of unconscious mental tendencies. In his view the problem for psychology is not why we are able to remember, but why we come to forget, and his own solution of the problem is that we forget the unpleasant, except when special factors make this forgetting impossible.
