It would be perfectly easy to give many other quotations from prominent psychologists who agree with Foerster and Muensterberg in this matter. What is forgotten is how large a role suggestion plays in all matters relating to conduct, but particularly sex conduct. The exhibition of such ordinary crimes as "second-story work", climbing porches in order to steal while the family are at meals, the picking of pockets and the like, on the reels of moving pictures has been found to be followed over and over again by the occurrence of such crimes among the boys and even the girls in the neighborhood where the exhibition was given. Girls see a woman's reticule cleverly rifled in a street car or on a crowded corner and, tempted by the cleverness of it, they are led to imitate the action. In many cities the police refuse to allow such reels to be exhibited unless the punishment for the crime completes the picture. Even with this, however, it has been found that such exhibitions prove criminally suggestive, for the young folks remember the cleverness and think of the fun that one can have with the money, while the punishment is, if not forgotten, at least so pushed into the background of memory as to have comparatively little deterrent effect. {192} If this is true with regard to indifferent actions of this kind, the temptations to which are more or less artificial or but of comparatively slight allurement, it is easy to understand how serious and profound can be the suggestive power of sex knowledge for which there is likely to be so prurient a curiosity and with regard to which there are in the best-regulated healthy individuals, bodily stirrings almost as soon as the mind begins to be occupied with them. For that is the danger,--that even in the best of men the physical sex impulse may be awakened. In those who for professional reasons are quite familiar with sex matters, as for instance the physician, the dwelling on sex subjects even in matters of disease may arouse physical elements in the system, and these may react to deepen the attention until other considerations may be quite pushed into the background of consciousness. If this is true for older people, how much more so for the young, who have not yet been disillusioned on sex subjects and whose inhibitions are likely to be so much weaker. A great many of the people who are so intent on sex education apparently do not realize that their very tendency to occupy themselves with this subject so much is due to unconscious physical stirrings within themselves, consequent upon the preoccupation of mind with these subjects to the exclusion of healthier considerations.
