G. K. C. on ugliness

Man may behold what ugliness he likes if he is sure that he will not worship it; but there are some so weak that they will worship a thing only because it is ugly. These must be chained to the beautiful. It is not always wrong even to go, like Dante, to the brink of the lowest promontory and look down at hell. It is when you look up at hell that a serious miscalculation has probably been made.

—G. K. Chesterton, ‘The Nightmare’
