A sympathetic disposition is as essential to the individual who wishes to be loved truly and permanently as all the other secondary psychic qualities. Cruel indifference is not incompatible with sensual love, but it is fatal to love based upon sentiment. Ordinary, sensual infatuation could be strong and unprincipled enough to lead a person to sacrifice honor and self-respect for the caprices of another. But true love would turn into contempt for the one who could wantonly subject it to persistent insults and degradation; and contempt is the death of genuine love, though yet compatible with sensual love.[AH] True love is, therefore, characterized by patience, kindness, generosity, humility, unselfishness, good temper, and sincerity. This spectrum of true love shows the same elements as does that of genuine friendship. True love, therefore, can only be acquired in the same way as true friendship, namely, after a long probationary interval. Then only will the true love supply the universal need of friendship. Marriage is no barrier to the existence of unselfish and sexless love, which is the essence of the truest and purest friendship. If a husband be truly the friend of his wife, his love for her as a friend would be just as strong, just as tender, just as permanent and unswerving as if she were not his wife, nor ever might be. Nay, it may be said with Tolstoy that unless married people have been united by pure love, without a mixture of animal passion, the time must come when they will become weary of each other.
