Evolution-Revolution

In nothing is there more evolution than the American mind. (Whitman)

Women is perpetual revolution, and is that element in the world which continually destroys and re-creates. (Warner)

Every revolution was first a thought in one man's mind; and when the same thought occurs to another man, it is the key to that era. (Emerson)

The Revolution must take place in men before it can be manifest in things. (Graffito)

Not actual suffering but the hope of better things incites people to revolt. (Hoffer)
