 Pomponazzi used the methods and language typical of the medieval scholastic tradition (Kraye 2010), primarily relying on reason and experience as the key tools for investigation. The former refers to the logical and philosophical principles of Aristotelianism, the latter refers to both quotidian experience and the experiences found in the writings of authorities, witnessed in testimonies of contemporaries, and taken from his own personal history. He had a critical attitude toward some humanist writers, for example, judging Giovanni Pico della Mirandola’s attack on astrology to be ignorant of the workings of the field. And while his Latin prose did not match the polished elegance of Renaissance humanists, in other ways his writings, through their extensive consideration of ancient philosophical and literary sources, reflect developments of humanism. Despite never learning Greek as many of his fellow philosophers did, including his rival Agostino Nifo, Pomponazzi relied on new translations of Greek commentators on Aristotle, most significantly those of Alexander of Aphrodisias (Kessler 2011). Furthermore, his later writings, especially On Incantations, take evidence from a broad range of Greek, Roman, and Renaissance poets and historians, interspersed among citations of the typical authorities of the scholastic traditions. In that work, he also discussed the possible natural causes of the Delphic oracle (see Ossa-Richardson 2010).
