Medicina e divinazione in Francisco Sanchez : il De divinatione per somnum ad Aristotelem

In F. Sanchez's De divinatione per somnum ad Aristotelem the reconsideration of philosophical thought on conjectural and empirical-inductive grounds aims at the medical practice through a conceptual link of an anti-Aristotelian probabilism of an Academical and Ciceronian (De divinatione) kind and a criticism of the dogmatism of Galenic medicine and of the Neoplatonic and Neopythagorian views of Renaissance physicians. Sanchez criticized the use of Hippocratic and Galenic divining theories and techniques that are linked to dreams in Cardano and in the bulk of Renaissance medical theory. Thus, the 'semiotics' of dreams developed by Auger Ferrier, Sanchez's Toulousian rival, is here used as a clue for the interpretation of his text.
