Insurrection of thought always precedes insurrection of arms.

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.

The only justification of rebellion is success.

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

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

All men recognize the right of revolution, that is, the right to refuse allegiance to, and to resist, the government, when its tyranny or its inefficiency are great and unendurable.

Revolutionaries are greater sticklers for formality than conservatives.

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.

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