"The law must be founded on principle. There must be absolutely no limits on liberty. In a free state, each and every citizen acts as a guardian of liberty. Everyone must be completely free to protest, in person or in print, at anything endangering liberty. If, as a consequence, public officials were to find themselves exposed to calumny, so be it. Incorruptible men, who have no other passion besides the well-being and glory of their country, do not dread the public expression of the sentiments of their fellow citizens. They know only too well that it is not easy to lose their esteem, when one can counter calumny with an irreproachable life and proof of disinterested zeal; if they are sometimes victims of a passing persecution, this is, for them, a badge of their glory, the brilliant testimony of their virtue; they rest assured with gentle confidence in the suffering of a pure conscience and the force of truth which will soon reconcile theirs with their fellow citizens."
Robespierre in his speech on freedom of the press on 7 April 1791 while addressing the Jacobin Club in Paris, France.
