We are shut up in school and college recitation rooms for ten to fifteen years, and come out at last with a bellyful of words and do not know a thing. We cannot use our hands, or our legs, or our eyes, or our arms. We do not know an edible root in the woods. We cannot tell our course by the stars, nor the hour of day by the sun. It is well if we can swim and skate. We are afraid of a horse or a cow, of a dog, of a cat, of a spider. Far better was the Roman rule to teach a boy nothing that he could not learn standing.

All the great ages have been ages of belief.

Go put your creed into your deed, Nor speak with double tongue.

Happy the man who never puts on a face, but receives every visitor with that countenance he has on.

No matter how often defeated, you are born to victory.

We can only be valued as we make ourselves valuable.

All science has one aim, namely, to find a theory of nature.
