I should affirm this question, which is one of the most frequent put to the psychotherapist. And yet, if I myself have entirely given up the cure of stammerers in recent years, it was not only because there was little chance to learn anything new scientifically from it but also because it was ultimately disappointing, as the severe cases cannot be cured entirely. Every hypnotist can quickly secure a strong improvement. In even new cases I found an almost surprising improvement in the first two weeks, an improvement which stirs up the most vivid hopes of the sufferers. Then the improvement becomes slower and finally it stops before a complete cure is reached. The patient notices it and it easily works back on his emotion and thus begins again to disturb the speech, unless a very careful continuous counter-suggestion is given. Slight disturbances, to be sure, can be removed entirely. The essential point will always be to suggest to the stammerer the full belief that he is able to speak every word and that he is able to speak it in every situation. But where there is a limit for improvement, we must take for granted that the disturbing fear is only superadded to an organic trouble. In such cases, probably the inability of certain nervous paths was primarily irreparable. These inabilities then became the source of discomfort and of fear and this fear added greatly to the disturbance. Hypnotism then quickly removes that part of the disturbance which had been superadded by the mental emotion but it cannot remove that primary factor, the objective inability, and every cure thus finds its limit there. Near the field of emotions stand also the many varieties of sexual abnormities and perversities. I abstain from discussing any special cases but it may be said that suggestive treatment is in this region powerful to an almost surprising degree. Even homosexual tendencies which go back to the beginnings of the memory of the individual yield, as my experience shows, in a few weeks, if again the suggestion is not so much directed towards the suppression as to the creation of the antagonistic reaction, that means in this case, of the normal sexual desire.
