case. Abandoning hypnosis, he developed another method which he called psycho-analysis. What chemical analysis is to chemistry, psycho-analysis is to the science of the mind. It splits up the mental content into its component parts, the better to be examined and modified by the conscious mind. Psycho-analysis is merely a technical process for discovering repressed complexes and bringing them into consciousness, where they may be recognized for what they are and altered to meet the demands of real life. It is a device for finding and removing the cause of nervousness,—for bringing to light hidden desires which may be honestly faced and efficiently directed instead of being left to seethe in dangerous insurrection. In order permanently to break up a real neurosis, a man must first know himself and then change himself. He must gain insight into his own mental processes and then systematically set to work to change those processes that unfit him for life.

We shall later find that a detailed self-discovery through psycho-analysis is not always necessary, and that a more general understanding of oneself is sufficient for the milder kinds of nervousness. But because of the promise which psycho-analysis holds out to those stubborn cases before which other methods are powerless; because of the invaluable understanding of human nature which it places at the disposal of all

nervous people, who may profit by its findings without undergoing an analysis; and because of the flood of light which it sheds on the motives, conduct, and character of every human being, no educated person can afford to be without a general knowledge of psycho-analysis.[41]

[41] ] It is unfortunate that the records of an analysis are too voluminous for use in so brief an account as this. Since the report of one case would fill a book, and a condensed summary would require a chapter, we must refer to some of the volumes which deal exclusively with the psychoanalytic principles. For a list of these books, see Bibliography.

A Chain of Associations. Psycho-analysis is not, like hypnosis, based on dissociation; it is based on the association of ideas. Its main feature is a process of uncritical thinking called "free association." To understand it, one must realize how intricately woven together are the thoughts of a human being and how trivial are the bonds of association between these ideas. One person reminds us of another because his hair is the same color or because he handles his fork in the same way. Two words are associated because they sound alike. Two ideas are connected because they once occurred to us at the same time. A subtle odor or a stray breeze serves to remind us of some old experience. Connections that seem far-fetched to other people may be quite strong enough to bind together in our minds ideas and emotions which have once been

associated, even unconsciously, in past experience.

In this way, thoughts in consciousness and in the upper layers of the subconscious are connected by a series of associations, forming links in invisible chains that lead to the deepest, most repressed ideas. Even a dissociated complex has some connection with the rest of the mind, if we only have the patience to discover it. Therefore, by adopting a passive attitude, by simply letting his thoughts wander, by talking out to the physician everything that comes to his mind without criticizing or calling any thought irrelevant or far-fetched, and without rejecting any thought because of its painful character, the patient is helped to trace down and unearth the troublesome complex which may have been absolutely forgotten for many years. He is helped to relive the childhood experiences back of the over-strong habits which lasted into maturity.

Resisting the Probe. Naturally, it is not all fair sailing. The subconscious impulses which repressed the painful complex in the first place still shrink from uncovering it. In many cases the resistance is very strong. It, therefore, often happens that after a time the patient becomes restive; he begins to criticize the doctor and to ridicule the method. His mind goes blank and no thought will come; or he refuses to tell what does come. The nearer the probe comes to the sore spot, the greater the pain of the repressing impulses

and the stronger the resistance. Usually a strange thing happens; the patient, instead of consciously remembering the forgotten experiences, begins to relive them with his original emotions transferred on to the doctor. Depending upon what person of his childhood he identifies with him, the patient develops either a strong affection or an intense antagonism to the physician, attitudes called in technical terms positive and negative transference. If the analyst is skilful, he is able to circumvent all the subterfuges of the resisting forces and to uncover and modify the troublesome complexes. Sometimes this can be accomplished at one sitting, but more often it requires long hours of conversation. Freud has spent three years on a single difficult case, and very frequently the analysis drags out through weeks or months. The amount of mental material is so great, especially in a person who is no longer young, that every analysis would probably be an interminable affair if it were not for three valuable ways of finding the clue and picking up the scent somewhere near the end of the trail. The first of these clues is nothing else than so despised a phenomenon as the patient's own night-dreams, which turn out to be not meaningless jargon, as we have supposed, but significant utterances of the inner man.

The Message of the Dream. When Freud rescued dreams from the mental scrap-basket and learned how
