deliver my lectures, I withdrew from academic life and ceased to attend the learned societies. It is a whole generation since I have visited the “Gesellschaft der Aerzte.” Anyone who wanted to make a living from the treatment of nerve-patients must clearly be able to do something to help them. My therapeutic arsenal contained only two weapons, electrotherapy and hypnosis, for prescribing a visit to a hydropathic establishment after a single consultation was an inadequate source of income. My knowledge of electrotherapy was derived from W. Erb’s text-book, which provided detailed instructions for the treatment of all the symptoms of nervous diseases. Unluckily I was soon driven to see that following these instructions was of no help whatever and that what I had taken for an epitome of exact observations was merely the construction of phantasy. The realization that the work of the greatest name in German neuropathology had no more relation to reality than some “Egyptian” dream-book, such as are sold in cheap book-shops, was painful, but it helped to rid me of yet another piece of the innocent faith in authority by which I was still obsessed. So I put my electrical apparatus aside, even before Möbius had solved the problem by explaining that the successes of electric treatment in nervous disorders (in so far as there were any) were the effect of suggestion on the part of the physician. With hypnosis the case was better. While I was still a student I had attended a public exhibition given by the “magnetist” Hansen and had noticed that one of the persons experimented upon had became deathly pale at the onset of cataleptic rigidity and had remained so as long as that condition lasted. This firmly convinced me of the genuineness of the phenomena of hypnosis. Scientific support was soon afterwards given to this view by Heidenhain; but that did not restrain the professors of psychiatry from declaring for a long time to come that hypnosis was not only fraudulent but dangerous and from regarding hypnotists with contempt. In Paris I had seen hypnosis used freely as a method for producing symptoms in patients and then removing them again. And now the news reached us that a school had arisen at Nancy which made an extensive and remarkably successful use of suggestion, with or without hypnosis, for therapeutic purposes. It thus came about, as a matter of course, that in the first years of my activity as a physician my principal instrument of work, apart from haphazard and unsystematic psycho-therapeutic methods, was hypnotic suggestion.
