“A popular Government without popular information, or the means of acquiring it, is but a Prologue to a Farce or a Tragedy, or perhaps both. Knowledge will forever govern ignorance: And a people who mean to be their own Governors, must arm themselves with the power which knowledge gives.”

Context: Theoretically "democracy" means popular government; government by all for everybody by the efforts of all. In a democracy the people must be able to say what they want, to nominate the executors of their wishes, to monitor their performance and remove them when they see fit.
Naturally this presumes that all the individuals that make up a people are able to form an opinion and express it on all the subjects that interest them. It implies that everyone is politically and economically independent and therefore no-one, to live, would be obliged to submit to the will of others. <!--
If classes and individuals exist that are deprived of the means of production and therefore dependent on others with a monopoly over those means, the so-called democratic system can only be a lie, and one which serves to deceive the mass of the people and keep them docile with an outward show of sovereignty, while the rule of the privileged and dominant class is in fact salvaged and consolidated. Such is democracy and such it always has been in a capitalist structure, whatever form it takes, from constitutional monarchy to so-called direct rule.

Variant translations:
The attribute of popular government in a revolution is at one and the same time virtue and terror. Terror without virtue is fatal; virtue without terror is impotent. The terror is nothing but justice, prompt, severe, inflexible; it is thus an emanation of virtue.
As quoted in Red Star Over Southern Africa (1988) by Morgan Norval, p. xvi
If the mainspring of popular government in peace time is virtue, its resource during a revolution is at one and the same time virtue and terror; virtue, without which terror is merely terrible; terror, without which virtue is simply powerless.
As quoted in Rousseau, Robespierre and English Romanticism (1999) by Gregory Dart
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.
Original French: La terreur n'est autre chose que la justice prompte, sévère, inflexible; elle est donc une émanation de la vertu ; elle est moins un principe particulier, qu’une conséquence du principe général de la démocratie, appliqué aux plus pressants besoins de la patrie.
