George Santayana,
The Sense of Beauty
(1896)
“ The fact of his pleasure at her smile is the ground of his instinctive belief in her pleasure in it. For this reason the circumstances expressive of happiness are not those that are favourable to it in reality, but those that are congruous with it in idea. The green of spring, the bloom of youth, the variability of childhood, the splendour of wealth and beauty, all these are symbols of happiness, not because they have been known to accompany it in fact, — for they do not, any more than their opposites, — but because they produce an image and echo of it in us aesthetically. ”
