The sitting posture, when long continued, excites the genital organs. Simon thinks so; because this attitude, by the pain and obstruction which it causes to the circulation, brings the blood to the lower parts of the trunk, and keeps it there: hence, it exposes the young man to excitement of the genital organs, and to engorgements of the spermatic cord: even hemorrhoids appear in those who ride and sit much. This author concludes by condemning the custom, in schools, of keeping the students sitting the greater part of the day. He thinks that the number of hours spent in school should be less, and that the students should study as many of their lessons as possible, in the erect posture. He recommends, also, that the seats should be so constructed as not to generate much heat, as do those which are stuffed. The action of intellectual labor is extremely analogous to that of muscular exertion. Persons whose minds are much occupied, who are devoted to their studies, are generally but slightly sensual in their feelings. There are some literary men who thus have become prematurely impotent. On the other hand, individuals whose minds are naturally dull and heavy, the imbeciles and idiots, are frequently remarkable for their extreme salacity. The cultivation of the intellect then is not in itself a predisposing cause of venereal abuses, but it may become so indirectly, either by the physical inaction which it demands, or by the nature of the ideas it excites. We have spoken of the former, and will now consider the latter. The moral influences, that is, those which are impressed on the senses through the medium of the intellect, often predispose young patients to the abuses of which we are treating. The action of these influences is direct: it is by the impressions which they develop, that they may give to the senses the power of holding a language, and of exercising a precocious influence. They are particularly to be dreaded when they address the instinct of propagation, and excite it before the organized system is perfectly developed. The moral education also, that education which consists in keeping from the young certain impressions, does not act until their time has come, and must be considered as one of the most efficacious modes of preventing the premature abuse of venereal pleasures.
