Grantaire was a man who took good care not to believe anything. He was, moreover, one of the students who had learned most during their course in Paris; ...[he] knew the good places for everything; furthermore, boxing, tennis, a few dances, and he was a profound cudgel-player. A great drinker to boot. He was frightfully ugly; the prettiest shoe-binder of that period, Irma Boissy, revolting at his ugliness, had uttered this sentence: "Grantaire is impossible," but Grantaire's self-conceit was not disconcerted. He looked tenderly and fixedly upon every woman, appearing to say of them all: 'if I only would'; and trying to make his comrades believe that he was in general demand.

All these words: rights of the people, rights of man, social contract, French Revolution, republic, democracy, humanity, civilization, religion, progress, were, to Grantaire, very nearly meaningless. He smiled at them. Skepticism... had not left one entire idea in his mind. He lived in irony. This was his axiom: There is only one certainty, my full glass. He ridiculed all devotion, under all circumstances... He said of the cross: "There is a gibbet which has made a success." A rover, a gambler, a libertine, and often drunk... Still, this skeptic had a fanaticism. This fanaticism was neither an idea, nor a dogma, nor an art, nor a science; it was a man: Enjolras.

...Grantaire, a true satellite of Enjolras, lived in this circle of young people; he dwelt in it; he took pleasure only in it; he followed them everywhere. His delight was to see these forms coming and going in the fumes of the wine. He was tolerated for his good-humour
