“Each new generation born is in effect an invasion of civilization by little barbarians, who must be civilized before it is too late.”
"One of the most dangerous errors instilled into us by nineteenth-century progressive optimism is the idea that civilization is automatically bound to increase and spread. The lesson of history is the opposite; civilization is a rarity, attained with difficulty and easily lost. The normal state of humanity is barbarism, just as the normal surface of our planet is salt water. Land looms large in our imagination of the planet and civilization in our history books, only because sea and savagery are, to us, less interesting.
And if you press to know what I mean by civilization, I reply “Humanity,” by which I do not mean kindness so much as the realization of the human idea. Human life means to me the life of beings for whom the leisured activities of thought, art, literature, conversation are the end, and the preservation and propagation of life merely the means. That is why education seems to me so important: it actualizes that potentiality for leisure, if you like for amateurishness, which is man’s prerogative.
You have noticed, I hope, that man is the only amateur animal; all the others are professionals. They have no leisure and do not desire it. When the cow has finished eating she chews the cud; when she has finished chewing she sleeps; when she has finished sleeping she eats again. She is a machine for turning grass into calves and milk—in other words, for producing more cows. The lion cannot stop hunting, nor the beaver building dams, nor the bee making honey. When God made the beasts dumb He saved the world from infinite boredom, for if they could speak they would all of them, all day, talk nothing but shop."
