Stendhal, on Love:

When heaven has endowed you with a soul made for love, not to love is to deprive yourself and others of great happiness. It is as if an orange-tree dared not flower for fear of committing a sin. And remember that a soul made for love can never be satisfied with any other kind of happiness. After its first taste of the much-vaunted pleasures of the world, it finds them intolerably dull, and though it often believes itself fond of Art and the sublimities of Nature, these merely lead the soul back to love, and more intensely than before, if that be possible. The soul soon realizes that it is being reminded of a happiness it has forsworn.
