Leave time, leave space, to grow. All our progress is an unfolding, like a vegetable bud. You have first an instinct, then an opinion, then a knowledge as the plant has root, bud, and fruit. If we stand still we will surely be drowned. To stay on the crest, we have to keep moving.
Unreasonable people attempt to adapt the world to themselves.
The reason for the slow progress of the world seems to lie in a single fact. Every man is born under the yoke, and grows up beneath the oppressions of his age. He can only get a vision of the unselfish forces in the world by appealing to them, and every appeal is a call to arms. If he fights he must fight, not one man, but a conspiracy. He is always at war with a civilization.
