"There can be no doubt that the individual who has once devoted himself to this moloch of the species becomes but too frequently its slave to an almost incredible degree. A patient who was sent to London for my advice confessed that he had practiced this vice seven or eight times daily from the age of thirteen until twenty-four; and he was then reduced to the lowest state of mental weakness, associated with various bodily infirmities; indeed, both mental power and physical existence were nearly extinguished." Testimony of Eminent Authors.--Says a medical writer, "In my opinion, neither the plague, nor war, nor small-pox, nor similar diseases, have produced results so disastrous to humanity as the pernicious habit of onanism; it is the destroying element of civilized societies, which is constantly in action, and gradually undermines the health of a nation." "The sin of self-pollution, which is generally considered to be that of Onan, is one of the most destructive evils ever practiced by fallen man. In many respects it is several degrees worse than common whoredom, and has in its train more awful consequences, though practiced by numbers who would shudder at the thought of criminal connection with a prostitute."[46] [Footnote 46: Dr. Adam Clarke.] "However revolting to the feelings it may be to enter upon such a subject, it cannot be passed over in silence without a great violation of duty. Unhappily, it has not been hitherto exhibited in the awful light in which it deserves to be shown. _The worst of it is that it is seldom suspected._ There are many pale faces and languid and nervous feelings attributed to other causes, when all the mischief lies here."[47] [Footnote 47: Sir W. C. Ellis.] We scarcely need add further evidence of the fearful extent of this evil, but will conclude with the following:-- "The pernicious and debasing practice of masturbation is a more common and extensive evil with youth of both sexes than is usually supposed." "A great number of the evils which come upon the youth at and after the age of puberty, arise from masturbation, persisted in, so as to waste the vital energies and enervate the physical and mental powers of man." "Many of the weaknesses commonly attributed to growth and the changes in the habit by the important transformation from adolescence to manhood, are justly referable to this practice."[48] [Footnote 48: Boston Medical and Surgical Journal.] Not a Modern Vice.--That this vice is not entirely a modern one is proved by the fact that in many ancient writings directions are given for treating its effects. Even Moses seems to have recognized disorders of this class. Hippocrates and others devoted considerable attention to them.
