“ The spring cannot coexist with the autumn, nor day with night; what is beautiful in a child is hideous in a man, and vice versa; every age, every country, each sex, has a peculiar beauty, finite and incommunicable; the better it is attained the more completely it excludes every other. ”
 George Santayana, The Sense of Beauty Being the Outlines of Aesthetic Theory (1896). copy citation

“As the Roman emperor wished that the Roman people had but a single neck, to murder them at one blow, so we may sometimes wish that all beauties had but one form, that we might behold them together. But in the nature of things beauties are incompatible. The spring cannot coexist with the autumn, nor day with night; what is beautiful in a child is hideous in a man, and vice versa; every age, every country, each sex, has a peculiar beauty, finite and incommunicable; the better it is attained the more completely it excludes every other. The same is evidently true of schools of art, of styles and languages, and of every effect whatsoever. It exists by its finitude and is great in proportion to its determination.
But there is a loose and somewhat helpless state of mind in which while we are incapable of realizing any particular thought or vision in its perfect clearness and absolute beauty, we nevertheless feel its haunting presence in the background of consciousness.” source
