I once knew a certain high school teacher, who believed religiously in every kind of freedom. When she married, she and her husband, an artist, made a vow against jealousy; but as it worked out, this vow meant that the wife had a steady job and took care of the husband, while he loafed and loved other women. When finally she grew tired of it, he accused her of being jealous; also, she had brought it down to the matter of money! I know another woman, an Anarchist, widely known as a lecturer on sex freedom. She laid down the general principle of unlimited personal freedom for all, and she tried to live up to her faith. She entered into a "free union" with a certain man, and when she discovered that he was making love to another woman, in the presence of a friend of mine she threw a vase of flowers at his head. You see, her general principles had clashed with another general principle, to the effect that a person who feels deep and strong love inevitably desires that love to endure, and cannot but suffer to see it preyed upon and destroyed. Let us first consider the question, just what are the true and proper implications of monogamous love? The Roman Catholic church advocates "monogamy," and understands thereby that a man and woman pledge themselves "till death do us part," and if either of them cancels this arrangement it is adultery and mortal sin. I hope that none of my readers understands by "monogamy" any such system of spiritual strangulation. My own idea is rather what some churchman has sarcastically described by the term "progressive polygamy." I believe that a man and woman should pledge their faith in love, and should keep that faith, and endeavor with all their best energies to make a success of it; they should strive each to understand the other's needs, and unselfishly to fulfill them, within the limits of fair play. But if, after such an effort has been truly made, it becomes clear that the union does not mean health and happiness for one of the parties, that party has a right to withdraw from it, and for any government or church or other power to deny that right is both folly and cruelty. Now, on the basis of this definition of monogamy--or, if you prefer, of progressive polygamy--we are in position to say what we think about jealousy. If two people pledge their faith, and one breaks it, and the other complains, we do not call that jealousy, but just common decency. Neither do we call it jealousy if one expects the other to avoid the appearance of guilt; for love is a serious thing, not to be played with, and I think that a person who truly loves will do everything possible to make clear to the beloved that he is keeping and means to keep the plighted faith.
