ABSTRACT
Suggestion plays an important part in the psychology of nations just as it does in the life of the individual, and it can sometimes be of supreme importance. In individual life suggestion plays an even bigger part. All education, for instance, depends, strictly speaking, on suggestion, for the transfer of ideas and intellectual content owes its strength solely to the suggestive resources at the disposal of the person in authority. The transferability of the delusional ideas depends among other things on their credibility, their plausibility. In contrast with the morbid processes that accord with this idea of induced insanity, the people are familiar with a large number of different forms of mental illness, ranging from infection with moods and affects in normal conditions by way of pathological anomalies of mood and superficially corrigible appropriation of morbid ideas all the way to the severest psychotic clinical pictures.
