14. CROWNING SIN OF THE AGE.--Then there is the crime of abortion which is so prevalent in these days. It is the crowning sin of the age, though in a broader sense it includes all those sins that are committed to limit the size of the family. "It lies at the root of our spiritual life," says Rev. B.D. Sinclair, "and though secret in its nature, paralyzes Christian life and neutralizes every effort for righteousness which the church puts forth." 15. SEXUAL EXHAUSTION.--Every sexual excitement is exhaustive in proportion to its intensity and continuance. If a man sits by the side of a woman, fondles and kisses her three or four hours, and allows his imagination to run riot with sexual visions, he will be five times as much exhausted as he would by the act culminating in emission. It is the sexual excitement more than the emission which exhausts. As shown in another part of this work, thoughts of sexual intimacies, long continued, lead to the worst effects. To a man, whose imagination is filled with erotic fancies the emission comes as a merciful interruption to the burning, harassing and wearing excitement which so constantly goads him. 16. THE DESIRE OF GOOD.--The desire of good for its own sake--this is Love. The desire of good for bodily pleasure--this is Lust. Man is a moral being, and as such should always act in the animal sphere according to the spiritual law. Hence, to break the law of the highest creative action for the mere gratification of animal instinct is to perform the act of sin and to produce the corruption of nature. 17. CAUSE OF PROSTITUTION.--Dr. Dio Lewis says: "Occasionally we meet a diseased female with excessive animal passion, but such a case is very rare. The average woman has so little sexual desire that if licentiousness depended upon her, uninfluenced by her desire to please man or secure his support, there would be very little sexual excess. Man is strong he has all the money and all the facilities for business and pleasure; and woman is not long in learning the road to his favor. Many prostitutes who take no pleasure in their unclean intimacies not only endure a disgusting life for the favor and means thus gained, but affect intense passion in their sexual contacts because they have learned that such exhibitions gratify men." 18. HUSBAND'S BRUTALITY.--Husbands! It is your licentiousness that drives your wives to a deed so abhorrent to their every wifely, womanly and maternal instinct a deed which ruins the health of their bodies, prostitutes their souls, and makes marriage, maternity and womanhood itself degrading and loathsome. No terms can sufficiently characterize the cruelty, meanness and disgusting selfishness of your conduct when you impose on them a maternity so detested as to drive them to the desperation of killing their unborn children and often themselves.
