To be able to fill leisure intelligently is the last product of civilization, and at present very few people have reached this level.

Every advance in civilization has been denounced as unnatural while it was recent.

A young man who had been troubling society with impalpable doctrines of a new civilization which he called "the Kingdom of Heaven" had been put out of the way; and I can imagine that believer in material power murmuring as he went homeward, "it will all blow over now." Yes. The wind from the Kingdom of Heaven has blown over the world, and shall blow for centuries yet.

I've made an odd discovery. Every time I talk to a savant I feel quite sure that happiness is no longer a possibility. Yet when I talk with my gardener, I'm convinced of the opposite.

No one gossips about other people's secret virtues.

Ethics is in origin the art of recommending to others the sacrifices required for cooperation with oneself.
