Insurrection of thought always precedes insurrection of arms.

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

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

Revolutions are not made by men in spectacles.

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.

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

Who draws his sword against his prince must throw away the scabbard.

No one makes a revolution by himself, and there are some revolutions which humanity accomplishes without quite knowing how, because it is everybody who takes them in hand.

There is a kind of revolution of so general a character that it changes the mental tastes as well as the fortunes of the world.
