My paper about the role played by Simplicius and the late antique commentary tradition in Presocratic studies has been published in 'Platonic Pathways'.

No fully extant text of Presocratic philosophy has survived antiquity. Occasionally, there are significant new discoveries such as the Strasbourg papyrus of Empedocles, but, as Runia commented in 2008, “even the students of early Hellenistic philosophy are better off” when it comes to source material. The modern scholar of early Greek philosophy is reliant on source books published in the shadow of the Diels-Kranz that collect together fragments and testimonia from later sources. Much of what we know about the Presocratics comes from Plato and Aristotle, but also from the Neoplatonic tradition, in the form of the explicit influences that the Presocratics had on particular Neoplatonic thinkers, and the wealth of verbatim fragments preserved in Neoplatonic texts.
This paper discusses the reception and transmission of early Greek philosophy through the lens of Neoplatonism, focusing on Simplicius’ commentaries on the works of Aristotle. Many of the fragments and testimonia that we have today come from Simplicius. However, there are issues surrounding our reliance on Simplicius’ commentaries. Why does Simplicius include extended references to Aristotle’s predecessors in his commentaries on Aristotle? Does the tendency to harmonize the doctrines of Plato and Aristotle in Neoplatonic works, known as the harmonization hypothesis, extend to Simplicius’ reportage of the Presocratics? The paper evaluates Simplicius’ contribution to Presocratic scholarship and asks what implications there are for our reading of the Presocratic fragments we receive from Simplicius.
