The articles collected here are based for the most part on papers read at the Colloquium “The
Placita of Aëtius: Foundations for the Study of Ancient Philosophy,” held in Melbourne in December 2015. The
Placita, a first century CE collection of systematically organised tenets in natural philosophy ranging from first principles to human physiology is incompletely extant in several later sources. Its laborious reconstruction and the identity of its author are discussed from various angles. The text of the treatise is further elucidated by a novel statistical exploration of what is extant and what is missing. Its relation to various currents in the history of Greek philosophy and its reliability are also examined in some detail.
Jaap Mansfeld is emeritus professor of Ancient and Medieval Philosophy in the University of Utrecht. He has published numerous papers and several monographs on ancient philosophy, among which (together with David T. Runia) the three previous volumes of Aëtiana.
David T. Runia is Director of the Institute for Religion and Critical Inquiry, Australian Catholic University, and also Professorial Fellow in the School of Historical and Philosophical Studies at the University of Melbourne. He has written widely on ancient philosophy, with a particular focus on the thought of Philo of Alexandria.
