It has indeed an egoistic side, including the ingredients I have called Individual Preference, Monopolism, Jealousy, Coyness, Hyperbole, Mixed Moods, and Pride; and it is not a mere accident that these are also the seven features which may be found in sensual love too; for sensuality and selfishness are twins. But the later and more essential characteristics of romantic love are the altruistic and supersensual traits--Sympathy, Affection, Gallantry, Self-sacrifice, Adoration, Purity, and Admiration of Personal Beauty. The two divisions overlap in some places, but in the main they are accurate. It is certain that the first group precedes the second, but the order in which the ingredients in each group first made their appearance cannot be indicated, as we know too little of the early history of man. The arrangement here adopted is therefore more or less arbitrary. I shall try in this long chapter to answer the question "What is Romantic Love?" by discussing each of its fourteen ingredients and tracing its evolution separately.
If a man pretended to be in love with a girl while confessing that he liked other girls equally well and would as soon marry one as another, everybody would laugh at him; for however ignorant many persons may be as to the subtler traits of sentimental love, it is known universally that a decided and obstinate preference for one particular individual is an absolute condition of true love.
As I have just intimated, a modern romantic lover would not exchange a beloved beggar-maid for an heiress or princess; nor would he give her for a dozen other girls, however charming, and with permission to marry them all. Now if romantic love had always existed, the lower races would have the same violent and exclusive preference for individuals. But what are the facts? I assert, without fear of contradiction from any one familiar with anthropological literature, that a savage or barbarian, be he Australian, African, American, or Asiatic, would laugh at the idea of refusing to exchange one woman for a dozen others equally young and attractive. It is not necessary to descend to the lowest savages to find corroboration of this view. Dr. Zöller, an unusually intelligent and trustworthy observer, says, in one of his volumes on German Africa (III., 70-71), that
