A promise to love someone forever, then, means, 'As long as I love you I will render unto you the actions of love; if I no longer love you, you will continue to receive the same actions from me, if for other motives.' Thus the illusion remains in the minds of one's fellow men that the love is unchanged and still the same.Friedrich Nietzsche

One must have a good memory to be able to keep the promises one has given. One must have strong powers of imagination to be able to have pity. So closely is morality bound to the quality of the intellect.Friedrich Nietzsche
