Perhaps the words, "a school of marriage," strike you as funny. When I was young I remember that Pulitzer founded a school of journalism, and all newspaper editors made merry--they knew that journalism could only be learned in practice. But nowadays every city editor gives preference to an applicant who has taken a college course in reporting; they have learned that journalism can be taught, just like engineering and accounting. In the same way I assert that marriage can be taught, and the art of love, physical, mental, moral, and even financial; I think that the day will come when enlightened parents would no more dream of trusting their tender young daughter to a man who had not taken a course in sex, than they would go up in an aeroplane with a pilot who knew nothing about an engine. The knowledge which I possess upon the art of love I would be glad to give you in this book; but unfortunately, if I were to do so, my book would be suppressed, and I should be sent to jail. Some ten or twelve years ago I received a pitiful letter from a man who was in state's prison in Delaware, charged with having imparted information as to birth control. Under our amiable legal system, a perfectly innocent man may be thrown into jail, and kept there for a year or two before he is tried, and if he is without money or friends, he might as well be buried alive. I went to Wilmington to call on the United States attorney who had caused the indictment in this case, and had an illuminating conversation with him. The official was anxious to justify what he had done. He assured me that he was no bigot, but on the contrary an extremely liberal man, a Unitarian, a Progressive, etc. "But Mr. Sinclair," he said, "I assure you this prisoner is not a reformer or humanitarian or anything like that. He is a depraved person. Look, here is something we found in his trunk when we arrested him; a pamphlet, explaining about sex relations. See this paragraph--it says that the pleasure of intercourse is increased if it is prolonged." I looked at the pamphlet, and then I looked at the attorney. "Do you think you have stated the matter quite fairly?" I asked. "Apparently the purpose is to explain that the emotions of women are more slow to be aroused than those of men, and that husbands failing to realize this, often do not gratify their wives." "Well," said the other, "do you consider that a subject to be discussed?" "Pardon me if I discuss it just a moment," I replied. "Do you happen to know whether the statement is a fact?" "No, I don't. It may be, I suppose." "You have never investigated the matter?" The legal representative of our government was evidently annoyed by my persistence. "I have not," he answered. "But then, suppose I were to tell you that thousands of homes have been broken up for lack of just that bit of knowledge; that tens of thousands of marriages are miserable for lack of it." "Surely, Mr. Sinclair, you exaggerate!"
