The essential of romantic love is that it regards the beloved object as very difficult to possess and as very precious. It makes therefore great efforts of many kinds to win the love of the beloved object, by poetry, by song, by feats of arms, or by whatever other method may be thought most pleasing to the lady. The belief in the immense value of the lady is a psychological effect of the difficulty of obtaining her, and I think it may be laid down that when a man has no difficulty in obtaining a woman, his feeling towards her does not take the form of romantic love.
