It so happened that I began to collect notes for a paper on "How to Cure Love." It was at first intended merely as a personal experiment in emotional psychology. Afterward it occurred to me that such a sketch might be shaped into a readable magazine article. This, again, suggested a complementary article on "How to Win Love"--a sort of modern Ovid in prose; and then suddenly came the thought, "Why not write a book on love? There is none in the English language--strange anomaly--though love is supposed to be the most fascinating and influential thing in the world. It will surely be received with delight, especially if I associate with it some chapters on personal beauty, the chief inspirer of love. I shall begin by showing that the ancient Greeks and Romans and Hebrews loved precisely as we love." Forthwith I took down from my shelves the classical authors that I had not touched since leaving college, and eagerly searched for all references to women, marriage, and love. To my growing surprise and amazement I found that not only did those ancient authors look upon women as inferior beings while I worshipped them, but in their descriptions of the symptoms of love I looked in vain for mention of those supersensual emotions and self-sacrificing impulses which overcame me when I was in love. "Can it be," I whispered to myself, "that, notwithstanding the universal opinion to the contrary, love is, after all, subject to the laws of development?" This hypothesis threw me into a fever of excitement, without the stimulus of which I do not believe I should have had the courage and patience to collect, classify, and weave into one fabric the enormous number of facts and opinions contained within the covers of _Romantic Love and Personal Beauty_. I believed that at last something new under the sun had been found, and I was so much afraid that the discovery might leak out prematurely, that for two years I kept the first half of my title a secret, telling inquisitive friends merely that I was writing a book on Personal Beauty. And no one but an author who is in love with his theme and whose theme is love can quite realize what a supreme delight it was--with occasional moments of anxious suspense--to go through thousands of books in the libraries of America, England, France, and Germany and find that all discoverable facts, properly interpreted, bore out my seemingly paradoxical and reckless theory. SKEPTICAL CRITICS When the book appeared some of the critics accepted my conclusions, but a larger number pooh-poohed them. Here are a few specimen comments: "His great theses are, first, that romantic love is an entirely modern invention; and, secondly, that romantic love and conjugal love are two things essentially different.... Now both these theses are luckily false." "He is wrong when he says there was no such thing as pre-matrimonial love known to the ancients."
