Maximilien Robespierre On the Justified Use of Terror

“If the spring of popular government in time of peace is virtue, the springs of popular government in revolution are at once virtue and terror: virtue, without which terror is fatal; terror, without which virtue is powerless. Terror is nothing other than justice, prompt, severe, inflexible; it is therefore an emanation of virtue; it is not so much a special principle as it is a consequence of the general principle of democracy applied to our country’s most urgent needs.
It has been said that terror is the principle of despotic government. Does your government therefore resemble despotism? Yes, as the sword that gleams in the hands of the heroes of liberty resembles that with which the henchmen of tyranny are armed. Let the despot govern by terror his brutalized subjects; he is right, as a despot. Subdue by terror the enemies of liberty, and you will be right, as founders of the Republic. The government of the revolution is liberty’s despotism against tyranny. Is force made only to protect crime? And is the thunderbolt not destined to strike the heads of the proud?”
