The patient had recovered and had remained well and, in fact, had become capable of doing serious work. But over the final stage of this hypnotic treatment there rested a veil of obscurity, which Breuer never raised for me; and I could not understand why he had so long kept secret what seemed to me an invaluable discovery instead of making science the richer by it. The immediate question, however, was whether it was possible to generalize from what he had found in a single case. The state of things which he had discovered seemed to me to be of so fundamental a nature that I could not believe it could fail to be present in any case of hysteria if it had been proved to occur in a single one. But the question could only be decided by experience. I therefore began to repeat Breuer’s investigations with my own patients and eventually, especially after my visit to Bernheim in 1889 had taught me the limitations of hypnotic suggestion, I worked at nothing else. After observing for several years that his findings were invariably confirmed in every case of hysteria that was accessible to such treatment, and after having accumulated a considerable amount of material in the shape of observations analogous to his, I proposed to him that we should issue a joint publication. At first he objected vehemently, but in the end he gave way, especially since, in the meantime, Janet’s works had anticipated some of his results, such as the tracing back of hysterical symptoms to events in the patient’s life, and their removal by means of hypnotic reproduction _in statu nascendi_. In 1893 we issued a preliminary paper, “On the Psychical Mechanism of Hysterical Phenomena,”[8] and in 1895 there followed our book, _Studien über Hysterie_.
