The Presocratics in the doxographical tradition. Sources, controversies, and current research

In this paper I present a synthetic overview of recent and ongoing research in the field of doxography, that is, the study of the nature, transmission and interrelations of sources for ancient Greek philosophy. The latest revisions of the theory of Hermann Diels (Doxographi Graeci 1879) regarding the historiography ought to be known more widely, as they still influence our understanding of the Presocratics and their reception. The scholarly study on the compilations of Greek philosophical views from Hellenistic and later periods has received a major boost by the first of a projected three-volume study by Mansfeld and Runia (1997). Taking their work as a firm basis I also describe my own work in this area and how it can be related to, and fitted into, this trend by outlining how two important sources for the historiography of Greek philosophy, Theophrastus (4th-3rd c. BCE) and Simplicius (early 6th c. AD) stand in a special relation to each other and form an important strand in the doxographical tradition.
