Immortality

But Love desires the beautiful; and then arises the question, What does he desire of the beautiful? He desires, of course, the possession of the beautiful;—but what is given by that? For the beautiful let us substitute the good, and we have no difficulty in seeing the possession of the good to be happiness, and Love to be the desire of happiness, although the meaning of the word has been too often confined to one kind of love. And Love desires not only the good, but the everlasting possession of the good. Why then is there all this flutter and excitement about love? Because all men and women at a certain age are desirous of bringing to the birth. And love is not of beauty only, but of birth in beauty; this is the principle of immortality in a mortal creature. When beauty approaches, then the conceiving power is benign and diffuse; when foulness, she is averted and morose.
