"To love is to value. The man who tells you that it is possible to value without values, to love those whom you appraise as worthless, is the man who tells you that it is possible to grow rich by consuming without producing and that paper money is as valuable as gold . . . . When it comes to love, the highest of emotions, you permit them to shriek at you accusingly that you are a moral delinquent if you’re incapable of feeling causeless love. When a man feels fear without reason, you call him to the attention of a psychiatrist; you are not so careful to protect the meaning, the nature and the dignity of love.
Love is the expression of one’s values, the greatest reward you can earn for the moral qualities you have achieved in your character and person, the emotional price paid by one man for the joy he receives from the virtues of another. Your morality demands that you divorce your love from values and hand it down to any vagrant, not as response to his worth, but as response to his need, not as reward, but as alms, not as a payment for virtues, but as a blank check on vices. Your morality tells you that the purpose of love is to set you free of the bonds of morality, that love is superior to moral judgment, that true love transcends, forgives and survives every manner of evil in its object, and the greater the love the greater the depravity it permits to the loved. To love a man for his virtues is paltry and human, it tells you; to love him for his flaws is divine. To love those who are worthy of it is self-interest; to love the unworthy is sacrifice. You owe your love to those who don’t deserve it, and the less they deserve it, the more love you owe them — the more loathsome the object, the nobler your love — the more unfastidious your love, the greater your virtue — and if you can bring your soul to the state of a dump heap that welcomes anything on equal terms, if you can cease to value moral values, you have achieved the state of moral perfection."
Ayn Rand, For the New Intellectual, 147
Agree. True love requires sacrifice. The only form of love that does not is so called self-love. But then you may ask if we should not love ourselves? But I will ask you in return are you talking about your flesh? Or your soul? How do you love your soul? But if you want to love your flesh, material nature of things which is temporary per se, what is noble in that? There is not much divine. But the source of true love is divine.
