Arnold Joseph Toynbee

History not used is nothing, for all intellectual life is action, like practical life, and if you don't use the stuff - well, it might as well be dead.

The world's greatest need . . . is mutual confidence. No human being ever knows all the secrets of another's heart. Yet there is enough confidence between mother and child, husband and wife, buyer and seller . . . to make social life a practical possibility. Confidence may be risky, but it is nothing like so risky as mistrust.

The supreme accomplishment is to blur the line between work and play.

America is a large, friendly dog in a very small room. Every time it wags its tail it knocks over a chair.

Civilization is a movement and not a condition, a voyage and not a harbor.

Civilizations, I believe, come to birth and proceed to grow by successfully responding to successive challenges. They break down and go to pieces if and when a challenge confronts them that they fail to meet.
