The stupidity of men always invites the insolence of power.

Every individual nature has its own beauty. One is struck in every company, at every fireside, with the riches of nature, when he hears so many new tones, all musical, sees in each person original manners, which have a proper and peculiar charm, and reads new expressions of face. He perceives that nature has laid for each the foundations of a divine building, if the soul will build thereon.

Wherever there is failure, there is some giddiness, some superstition about luck, some step omitted, which, Nature never pardons.

In spite of warnings, change rarely occurs until the status quo becomes more painful than change. People seem not to see that their opinion of the world is also a confession of their character.

Revolutions go not backward.

The law of nature is alternation for evermore. Each electrical state superinduces the opposite.

Courage consists in equality to the problem before us.
