All minds quote. Old and new make the warp and woof of every moment. There is no thread that is not a twist of these two strands. By necessity, by proclivity, and by delight, we all quote. We quote not only books and proverbs, but arts, sciences, religion, customs, and laws; nay, we quote temples and houses, tables and chairs, by imitation.

The first and last lesson of religion is, "The things that are seen, are temporal; the things that are unseen, are eternal." It puts an affront upon nature.

Everything in nature goes by law, and not by luck.

I hear therefore with joy whatever is beginning to be said of the dignity and necessity of labor to every citizen. There is virtue yet in the hoe and the spade, for learned as well as for unlearned hands. And labor is everywhere welcome; always we are invited to work; only be this limitation observed, that a man shall not for the sake of wider activity sacrifice any opinion to the popular judgments and modes of action.

Nothing is at last sacred but the integrity of your own mind.

Do what you know and perception is converted into character.

The aid we can give each other is only incidental, lateral, and sympathetic.
