Yet another evil, frequently met, must also be shortly touched upon. Excessive sexual indulgence is infinitely more harmful than too little. A body, misused by excess, will go to pieces, even without venereal diseases. Impotence, barrenness, spinal affections, insanity, at least intellectual weakness, and many other diseases, are the usual consequences. _Temperance_ is as necessary in sexual intercourse as in eating and drinking, and all other human wants. But temperance seems difficult to youth. Hence the large number of "young old men," in the higher walks of life especially. The number of young and old _roues_ is enormous, and they require special irritants, excess having deadened and surfeited them. Many, accordingly, lapse into the unnatural practices of Greek days. The crime against nature is to-day much more general than most of us dream of: upon that subject the secret archives of many a Police Bureau could publish frightful information. But not among men only, among women also have the unnatural practices of old Greece come up again with force. Lesbian love, or Sapphism, is said to be quite general among married women in Paris; according to Taxal,[121] it is enormously in practice among the prominent ladies of that city. In Berlin, one-fourth of the prostitutes are said to practice "tribady;" but also in the circles of our leading dames there are not wanting disciples of Sappho. Still another unnatural gratification of the sexual instinct manifests itself in the violation of children, a practice that has increased greatly during the last thirty years. In France, during 1851-1875, 17,656 cases of this nature were tried. The colossal number of these crimes in France is intimately connected with the two-child system, and with the abstinence of husbands towards their wives. To the German population also we find people recommending Malthusianism, without stopping to think what the sequels will be. The so-called "liberal professions," to whom belong mainly the members of the upper classes, furnish in Germany about 5.6 per cent. of the ordinary criminals, but they furnish 13 per cent. of the criminals indicted for violation of children; and this latter percentage would be still higher were there not in those circles ample means to screen the criminals, so that, probably, the majority of cases remain undiscovered. The revelations made in the eighties by the "Pall Mall Gazette" on the violation of children in England, are still fresh in the public memory. The moral progress of this our best of all possible worlds is recorded in the below tables for England, the "leading country in civilization." In England there were:--
