Our social conditions have created a profound contradiction between man as a sex being and man as a social being. This contradiction has never been so noticeable as in the present age, and it leads to many evils and diseases to which women especially are subjected. In the first place the woman’s organism is far more influenced by her sex mission than man’s organism (for instance, the regular recurrence of menstruation); in the second place she is confronted by the greatest number of obstacles that prevent her from satisfying her strongest natural impulse in a natural way. This contradiction between natural impulse and social constraint leads to anomalies, to secret vices and excesses that are bound to undermine even strong constitutions. Unnatural satisfaction is frequently aided in a most shameless manner. In the advertisements of newspapers and periodicals, certain manufactures are recommended in a more or less veiled manner. These advertisements appeal to the wealthy classes of society, because the price of the manufactures are so high that a person of moderate means could not buy them. Besides we find advertisements of obscene pictures, entire series of photographs, and poetry and prose of a similar character, whose very titles are intended to produce sensual excitement. These matters ought to claim the attention of the police and public prosecutors. But these gentlemen are too busy persecuting Socialism, “that will destroy the home and the family,” to give their full attention to such doings. A part of our novels influence the sentiments of the reading public in the same direction. It is really not to be wondered at if sexual debauchery, artificially stimulated, gradually becomes a social disease. Many women of the wealthy classes lead an idle, self-indulgent life. They stimulate their nerves by the most extraordinary means, and indulge in a certain enjoyment of art that creates an exaggerated sentimentality and heightens their nervous irritability. All this increases the sensual passions and naturally leads to excesses. Among poor people sexual irritability is frequently heightened by certain kinds of hard work, especially such work that compels people to lead a sedentary life which creates congestion of the blood in the abdominal organs. One of the most dangerous occupations in this respect is constant work at the sewing machine, an occupation in which a great many women are employed at present. This work is so detrimental to the health of women that ten to twelve hours of it daily will shatter the strongest constitution in a few years. Excessive sexual irritability is also brought about by long hours of work in a high temperature, for instance in sugar refineries, laundries, printing establishments, etc. The same may be said of night work with artificial light in overcrowded work-shops, especially where members of both sexes work together.
