Revolutions never go backwards.

The value of a principle is the number of things it will explain; and there is no good theory of disease which does not at once suggest a cure.

Self-command is the main elegance.

The effects of opposition are wonderful. There are men who rise refreshed on hearing of a threat, — men to whom a crisis which intimidates and paralyzes the majority — demanding, not the faculties of prudence and thrift, but comprehension, immovableness, the readiness of sacrifice — comes graceful and beloved as a bride!

Nothing is rich but the inexhaustible wealth of Nature. She shows us only surfaces, but she is million fathoms deep.

Nature is no sentimentalist, — does not cosset or pamper us. We must see that the world is rough and surly, and will not mind drowning a man or a woman, but swallows your ships like a grain of dust. The cold, inconsiderate of persons, tingles your blood, benumbs your feet, freezes a man like an apple. The diseases, the elements, fortune, gravity, lightning, respect no persons.

Nature is too thin a screen; the glory of the One breaks in everywhere.

The person who screams, or uses the superlative degree, or converses with heat, puts whole drawing-rooms to flight. If you wish to be loved, love measure. You must have genius or a prodigious usefulness if you will hide the want of measure.

Nature is the best posture-master.

I have seen manners that make a similar impression with personal beauty, that give the like exhilaration and refine us like that; and in memorable experiences they are suddenly better than beauty, and make that superfluous and ugly. But they must be marked by fine perception, the acquaintance with real beauty. They must always show control; you shall not be facile, apologetic, or leaky, but king over your word; and every gesture and action shall indicate power at rest. They must be inspired by the good heart. There is no beautifier of complexion, or form, or behavior, like the wish to scatter joy, and not pain, around us.
