The most satisfactory way for the uninitiated to make himself familiar with the technique of psychoanalysis is to submit himself to psychoanalysis. For that purpose one turns to an experienced analyst, and takes to him one's ideas and dreams. Consequently I submitted myself for two months to analysis from Dr. Jung, who in that way initiated me into the practice of psychological investigation. The interpretation of one's own dreams, reading and studying of the principal literature about analytical psychology or deep psychology, as Bleuler calls it; and the application of what is thus learned, at the start to simple, later to more difficult cases, must do the rest in making an independent investigator in this branch of psycho-therapy. As has already been said, psychoanalysis aims at bringing into consciousness all the forgotten things. When all the gaps in the memory are filled in, when all the puzzling operations of the psychological life are explained, then the continuance and the return of the suffering has become impossible. The attainment of this ideal state is truly the attainment of Utopia. Most certainly a treatment does not need to be carried so far. One may be satisfied with the practical cure of the patient, with the restoration of his power for work, and with the abolition of the most difficult functional disturbances. It is applicable in cases of chronic psychoneurosis which exhibit no difficult or dangerous phenomena. Among these are counted all sorts of compulsive neuroses, compulsive thoughts, compulsive behavior and cases of hysteria, where phobias and obsessions play a chief role, also somatic phenomena of hysteria which do not need to be acted upon quickly, such as, for example, anorexia. In acute cases of hysteria it is better to wait for a calmer period before applying psychoanalysis. In cases of nervous prostration this manner of treatment, which demands the serious co-operation and attention of the patient, which lasts a long time and at first takes no notice of the continuance of the phenomena, is difficult. This form of psychotherapy places great demands on the physician's patience and understanding. Psychoanalyses which last more than a year, are no rarity. It cannot be applied to the seriously degenerated; to people who have passed far beyond middle life, because among the last named the accumulated material compasses too much; to those who are entangled in a state of great fear and who live in deep depression. Analysis can be applied to the neuroses of children. It is desirable in those cases for the physician to be supported by a trusted person, as for example a woman assistant, but preferably by parents enlightened sufficiently to observe the spontaneous remarks of the child, to make notes of them, and communicate them to the physician. According to the experiments undertaken by the Zurich school, the expectation is justified within certain limits, that psychoanalysis will be
