Science does not know its debt to imagination.

Success goes thus invariably with a certain plus or positive power: an ounce of power must balance an ounce of weight.

For all men live by truth, and stand in need of expression. In love, in art, in avarice, in politics, in labor, in games, we study to utter our painful secret. The man is only half himself, the other half is his expression.

The sum of wisdom is that time is never lost that is devoted to work.

There is virtue yet in the hoe and the spade, for learned as well as for unlearned hands. And labor is everywhere welcome; alwayswe are invited to work.

Who can . . . guess how much industry and providence and affection we have caught from the pantomime of brutes?

Each man has an aptitude born with him. Do your work.
