Those who make peaceful revolution impossible will make violent revolution inevitable.

The peasants alone are revolutionary, for they have nothing to lose and everything to gain. The starving peasant, outside the class system, is the first among the exploited to discover that only violence pays. For him there is no compromise, no possible coming to terms. 

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

I have been ever of the opinion that revolutions are not to be evaded.

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.

The spirit of revolution, the spirit of insurrection, is a spirit radically opposed to liberty.

Revolutionaries are greater sticklers for formality than conservatives.

And then, sir, there is this consideration: that if the abuse be enormous, nature will rise up and, claiming her original rights, overturn a corrupt political system.

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