 Vives’ career as a leading northern European humanist starts with the publication in 1519 of In pseudodialecticos, a satirical diatribe in which he voices his opposition to scholastic logic on several counts. He follows in the footsteps of earlier humanists such as Lorenzo Valla (1406–57) and Rudolph Agricola (1443–85), who set about to replace the scholastic curriculum, based on syllogistic and disputation, with a treatment of logic oriented toward the use of the topics, a technique of verbal association aiming at the invention and organization of material for arguments, and persuasion. Vives’ severe censure of scholastic logic derived from his own unhappy experience with the scholastic curriculum at Paris. Therefore, as he himself emphasized, no one could accuse him of “condemning it because he did not understand it” (Opera omnia, 1964, III, 38; all quotations below are from this edition). Erasmus wrote to More that no one was better suited for the battle against the dialecticians, in whose ranks he had served for many years.
