=Influence of Modern Civilization. Pornography.=--Human sexuality has been unfortunately perverted and in part grossly altered by civilization, which has even developed it artificially in a pathological sense. The point has been reached of considering as normal, relations which are in reality absolutely abnormal. For example, it is maintained that prostitution produces normal coitus in man. How can this term be seriously employed in speaking of connection with a prostitute who is absolutely indifferent to it, and who seeks only to excite her clients artificially and to get their money, without mentioning venereal diseases which she so often presents them with! Forgetful of the natural aim of the sexual appetite, civilization has transformed it into artificial enjoyment, and has invented all possible means to increase and diversify it. As far back as the history of civilization goes we see this state of affairs, and in this sense we are neither better nor worse than our ancestors. But we possess more diverse and more refined measures than barbarian peoples, and than our direct ancestors, to satisfy our unwholesome desires. Modern art in particular often serves to excite eroticism, and we must frankly admit that it often descends to the level of pornography. Hypocritical indignation against those who dare to say this often serves only to cover in the name of art the most indecent excitants of eroticism. Photography and all the perfected methods of reproduction of pictures, the increasing means of travel which facilitate clandestine sexual relations, the industrial art which ornaments our apartments, the increasing luxury and comfort of dwellings, beds, etc., are, at the present day, so many factors in the science of erotic voluptuousness. Prostitution itself has become adapted to all the pathological excrescences of vice. In a word, the artificial culture of the human sexual appetite has given rise to a veritable high school of debauchery. The artistic and realistic representations of erotic sexual scenes, so widespread at the present day, are much more capable of exciting the sexual appetite than the crude and unnatural pictures of former days, when, however, erotic objects of art generally belonged to a few rich persons or to museums.
