The most radical revolutionary will become a conservative on the day after the revolution.

All successful revolutions are the kicking in of a rotten door. The violence of revolutions is the violence of men who charge into a vacuum.

Revolutions are celebrated when they are no longer dangerous. 

Revolutions have never lightened the burden of tyranny, they have only shifted it to another shoulder.

It is better to die on your feet than to live on your knees.

To cast aside obedience, and by popular violence to incite revolt, is treason, not against man only, but against God.

The only justification of rebellion is success.

An oppressed people are authorized, whenever they can, to rise and break their fetters.

If not us, who? If not now, when?

If there was ever a just war since the world began, it is this in which America is now engaged.

Nothing is more unpredictable than the mob, nothing more obscure than public opinion, nothing more deceptive than the whole political system.

Revolution can never be forecast; it cannot be foretold; it comes of itself. Revolution is brewing and is bound to flare up.

The brutalities of progress are called revolutions. When they are over we realize this: that the human has been roughly handled, but that it has advanced.
