 Besides these commentaries of Simplicius which have been preserved, the "de Anima" commentary mentions explanations on the metaphysical books, and an epitome of the "Physica" of Theophrastus.Simplicius, as a Neoplatonist, endeavoured to show that Aristotle agrees with Plato even on those points which he controverts, so that he may lead the way to their deeper, hidden meaning.In his view not only Plotinus, but also Syrianus, Proclus, and Ammonius, are great philosophers, who have penetrated into the depths of the wisdom of Plato.
