Abstract: The skepticism of the New Academy, as presented by the Dialogues of Guy de Bruès (1555), is identified with a position that is amoral or too radical to be systematically refuted. Confronted with its sources, however, this work reveals a more precise image of this philosophy, although in a hidden way. I argue that this apparent paradox will be resolved once the work is placed in the literary context of Renaissance declamatio and philosophical dialogue.
