Abstract: With his Discours philosophiques (1579), the young Calvinist Pierre de Lostal (1559 ?-1621 ?), presents a summary of metaphysics and ethics, to foster a political goal: he contradicts Bodin. He is famous for the Soldat françois (1604) that incites, in a very emphatic style, to fight against Spain. The Discours share many authorities with the Essais, such as Plutarch, Cicero, and Seneca, but the author’s Neoplatonism, and baroque emotional aesthetics, move him away from Montaigne.
