Like Alexander of Aphrodisias and Themistius, he saw himself as a commentator explaining the doctrines of Plato and Aristotle. But in his Enneads he went further than those authors, often working from passages which had been presented more tentatively, possibly inspired partly by earlier authors such as the neopythagorean Numenius of Apamea. Neoplatonism provided a major inspiration to discussion concerning the intellect in late classical and medieval philosophy, theology and cosmology.
