 Sturm is well-versed in the Aristotelian commentary tradition including the Greek commentators rediscovered in the Renaissance (Schmitt 1983), such as Iamblichus, Alexander of Aphrodisias, Themistius, Ammonius Hermeae, Simplicius of Cilicia, Philoponus (John the Grammarian), and Olympiodorus the Younger; the Arab commentators, such as Avicenna and Averroës; as well as the Latin commentators, such as Albertus Magnus, Thomas Aquinas, Duns Scotus, Durandus of St. Pourçain, and William of Ockham. Following a general line of thought manifesting itself in the Renaissance among both Aristotelian and Humanist thinkers (Schmitt 1983), Sturm takes the Greek commentators to be more reliable and true to the views of Aristotle himself than the Latin commentators (PE I: preface).
