The collection of nineteen articles in Jaap Mansfeld’s Studies in Early Greek Philosophy span the period from Anaximander to Socrates. Solutions to problems of interpretation are offered through a scrutiny of the sources, and also of the traditions of presentation and reception found in antiquity. Excursions in the history of scholarship help to diagnose discussions of which the primum movens may have been forgotten. General questions are treated, for instance the phenomenon of detheologization in doxographical texts, while problems relating to individual philosophers are also discussed. For example, the history of Anaximander’s cosmos, the status of Parmenides’ human world, and the reliability of what we know about the soul of Anaximenes, and of what Philoponus tells us about the behaviour of Democritus’ atoms.
