All civilization has from time to time become a thin crust over a volcano of revolution.

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

Revolutions are not about trifles, but they are produced by trifles. 

This country, with its institutions, belongs to the people who inhabit it. Whenever they shall grow weary of the existing government, they can exercise their constitutional right of amending it, or their revolutionary right to dismember or overthrow it.

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.

All revolutions devour their own children.

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

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.
