How little do the most wonderful inventions of modern times detain us. They insult nature. Every machine, or particular application, seems a slight outrage against universal laws.

Mathematics should be mixed not only with physics but with ethics.

The rich man is always sold to the institution which makes him rich. Absolutely speaking, the more money, the less virtue.

When I hear music, I fear no danger. I am invulnerable.

A worm is as good a traveler as a grasshopper or a cricket, and a much wiser settler. With all their activity these do not hop away from drought nor forward to summer. We do not avoid evil by fleeing before it, but by rising above or diving below its plane; as the worm escapes drought and frost by boring a few inches deeper.

The most I can do for my friend is simply to be his friend. I have no wealth to bestow on him. If he knows that I am happy in loving him, he will want no other reward. Is not friendship divine in this?

Very few men can speak of Nature, for instance, with any truth. They overstep her modesty, somehow or other, and confer no favor.They do not speak a good word for her. Most cry better than they speak, and you can get more nature out of them by pinching than by addressing them. The surliness with which the woodchopper speaks of his woods, handling them as indifferently as his axe, is better than the mealy-mouthed enthusiasm of the lover of nature. Better that the primrose by the river's brim be a yellow primrose, and nothing more, than that it be something less.
