[2] His second novel, Émilie de Varmont (1791), was intended to prove the utility and necessity of divorce and of the marriage of priests,[3] questions raised by the French Revolution; all his works tended to advocate revolutionary ideals.

[4] He attempted to have one of his unpublished plays, L'Anoblié conspirateur, performed at the Comédie-Française, and records that one of its managers, d'Orfeuil, listened to the reading of the first three acts impatiently, exclaiming at last: "I should need cannon in order to put that piece on the stage".

A sort of farce at the expense of the army of the Royalist émigrés, La Grande Revue des armes noire et blanche, had, however, better success: it was on stage for twenty-five nights.

[4] A self-styled philosophe and radical revolutionary, Louvet subsequently campaigned against despotism and reaction, which he identified with the moderate constitutional monarchy advocated by the Marquis de la Fayette, the Abbé Maury, and other disciples of Niccolò Machiavelli.

[4] He attached himself to the Girondists, whose vague deism, sentimental humanitarianism and ardent republicanism he fully shared, and from March to November 1792 he published, at Jean Marie Roland's expense, a bi-weekly journal-affiche, of which the title, La Sentinelle,[1] proclaimed its mission to open all of Europe to the Enlightenment at a time when, after the Habsburg declaration of war on France and the outbreak of the French Revolutionary Wars, a schism between the king and his subjects had become obvious.

On 10 August (the effective fall of the Monarchy), Louvet became editor of the Journal des Débats and, both as a journalist and deputy in the National Convention, made himself conspicuous by his attacks on Maximilien Robespierre, Jean-Paul Marat and the other Montagnards,[3] whom he later claimed he would have succeeded in bringing to justice after the September Massacres were it not for the poor support he received from the Girondist leaders.

[8][page needed] Commenting on the control that Robespierre ensured in Paris 1792 French National Convention election in which many candidates were disqualified Louvet said "Almost always at the moment despotism is overthrown agitateurs appear formenting anarchy to oppress and tyranize in their turn".

After the onset of the Thermidorian Reaction and the fall of Robespierre (27 July 1794), he was recalled to the Convention, when he was instrumental in bringing Jean-Baptiste Carrier and the others responsible for the drownings at Nantes to justice.
