He was also continuing his studies, which almost from the start seem to have turned toward the psychic side of the medical science. The new methods of hypnotism and suggestion interested him greatly, and in 1889 he published a monograph on "Functional Aphonia and its Treatment by Hypnotism and Suggestion." In 1888 he made a study trip to England, during which he wrote a series of "London Letters" on medical subjects for his father's journal. On his return he settled down as a practicing physician, but continued to act as his father's assistant. And as late as 1891-95 we find him named as his father's collaborator on a large medical work entitled "Clinical Atlas of Laryngology and Rhinology." There are many signs to indicate uncertainty as to his true calling during those early years. The ensuing inner conflict was probably sharpened by some pressure exercised by his father, who seems to have been anxious that he should turn his energies undividedly to medicine. To a practical and outwardly successful man like the elder Schnitzler, his own profession must have appeared by far the more important and promising. While there is no reason to believe that his attitude in this matter was aggressive, it must have been keenly felt and, to some extent at least, resented by the son. One of the dominant notes of the latter's work is the mutual lack of understanding between successive generations, and this lack tends with significant frequency to assume the form of a father's opposition to a son's choice of profession. This conflict cannot have lasted very long, however, for the younger Schnitzler proved quickly successful in his purely literary efforts. The "Anatol" sketches attracted a great deal of attention even while appearing separately in periodicals, and with their publication in book form, which occurred almost simultaneously with the first performance of "A Piece of Fiction" at a Viennese theater, their author was hailed as one of the most promising among the younger men. From that time he has been adding steadily to his output and his reputation. When his collected works were issued in 1912, these included four volumes of plays and three volumes of novels and stories. Since then he has finished another play and two volumes of prose sketches.
