 One should also pay attention to Mauricio Beuchot (Mexico) (1996, 2003) who devoted two papers to skepticism in the Middle Age. His point is that skepticism attracted some attention even before Renaissance. According to him, many medieval authors developed skeptical positions. Among them, Augustine’s Platonic Christianity appealed to Academic skepticism in its theory of illumination, in which Augustine emphasized the fallibility of human knowledge; Averroes’ theory of double truth, according to which there are two kinds of truth (truths for science and truths for faith) similarly has a skeptical tone, and those who thought that God could perhaps fool us were considering skeptical argument (Ockham, Pedro Lombardo, Tomás de Aquino and Buenaventura, among others). Beuchot also remembers that Nicolás d’Autrecourt, a French monk (1300–1350 approximately), active in the University of Paris, anticipated Humean skepticism concerning causality.
