The constituents of the average marriage are a man over-stimulated sexually by mystery and ignorance, and a woman abnormally undersexed by the course of self-repression and self-mutilation which have been taught her from her earliest childhood as necessities of modesty, purity and virtue. And then out of the carefully cultivated repugnance of the woman and the savage, exulting, unrelenting passion of the man are produced children, frequently welcome, seldom premeditated. And we are asked to believe that out of such elements are created the best foundation for a race or nation. Surely, surely, that combination of conditions is the best for a race or a nation which produces the best individuals; and quite as surely we should strive to bring about those conditions which tend to produce the best individuals. Then there is home. Home, sweet home! the perfect flower, we are told, that blooms on the fair stem of marriage. Yet it is the very citadel of ignorance, when it should be the school in which are taught the beautiful phenomena of physical life. Home! where the simplest, purest facts of life are converted into a nasty mystery and deliberately endowed with the characteristics of impurity and sin; for what else is the meaning of that solemn formula, which most of us have been taught, that we were conceived in sin? What else is the meaning of the hush and blush that go to any reference to sex, sign or manifestation of sex? Is it not awful beyond the power of words to express that a man and a woman come together in ignorance and beget children who are not even to obtain the benefit of such knowledge as their unfortunate parents pick up by the way, but must themselves begin the most responsible functions of life, not only in equal ignorance, but with an added load of misconceptions, sex-superstitions, immoral dogmas and probably physical disabilities? A short time since a father was speaking to me of his son, fourteen years of age, and plainly at an age when some of the beautiful phenomena of sex-life were beginning to crowd upon him for notice. I asked the man if he had talked with his son about the matter. His answer was peculiar only in that he put into words a description of the attitude of the average parent: "Talked to him about that? Not I. Let him learn as I did. No one ever told me." But some one had told him, as his unpleasantly reminiscent smile advised me! He had been told by ignorant companions, by ignorant servants, and, quite likely, by books, whose grossness would have been harmless but for the child's piteous ignorance. No, the man would not talk with his son about such things, but he would go into his club and talk into the small hours over a glass of whiskey with his friends there, turning the beauty and purity of sex manifestation into shabby jest and impure ridicule. He would exchange stories based on sex relation with any stranger with whom he might ride for two hours in a smoking car. Every man knows that I speak well within
