[CE] Le Pileur says: Lessons to young girls, showing them the dangers to which they expose themselves, can only have a favorable influence. Perhaps the physicians of Saint-Lazare will then hear no more, from at least one-fourth of all these unfortunate girls in this institution, that they have given themselves to some stranger. We will not hear twenty per cent. of them answer that they have allowed themselves to be defloured out of curiosity, to know what it is, to be as smart as their friends. This ignorance is due to the fact that the majority of parents have no more knowledge of sex than what is known to every animal by instinct. Pinard (Chronique Médicale, 1903, p. 488) says: “Jusqu’à présent l’acte procréateur n’a été qu’un acte instinctif tel qu’il existait à l’âge des cavernes, c’est le seul de nos instincts n’ayant pas été civilisé. L’acte est accompli à l’aurore du XXe siècle comme à l’âge de pierre.” [CF] The Sanitarian (March, 1904) claims that not one per cent. of prostitutes are able to read or write because they are of such a low order of intelligence that they cannot be educated. [CG] What are a few generations in the history of humanity? One to two centuries represent only a short space of time. Prostitution is older than history. The Hammurabi codex, paragraph 100, has already rules about Hierodules, or girls consecrated to the service of Venus. Moses, Deuteronomy xxiii, 18, commands: “There shall be no temple prostitute of the daughters of Israel.” Still prostitution existed among the Jews as seen by I. Regum, xiv, 24; xv, 12; xxii, 46; II. Regum, xxiii, 7; Amos, ii, 7; Hosea, iv, 14. At this point the prophet distinguishes between the common and the temple prostitute. If such an ancient institution could be banished from this earth by eugenics within a few centuries, humanity could be satisfied. [CH] If the symbol of inheritance be placed as 1, and the symbol of environment as 0, both together will give the figure 10; each alone amounts to little in one case and to nothing in the other. [CI] These conditions are now noticed even in our young country, where not only the native of the Anglo-Saxon stock sets a limit to his offspring but also the immigrant, who begins the same practices as soon as he has reached a higher step of the social ladder. The same Russian Jewess who in her native country set her pride to follow the religious dictates of her race to increase and multiply, the same Italian or Irish woman who in her native country would not have thought of defying the tenets of the Catholic church regarding the limitation of offspring, will ask her physician for some anti-conceptional remedy, as soon as she has reached a certain degree of affluence. With wealth and power come love for luxury and ease, and the consequence is the limitation of the offspring.
