Barbara Sattler is professor for ancient and medieval philosophy at Bochum University, and has taught at St. Andrews, Yale, and Urbana-Champaign before. The main areas of her research are issues in metaphysics and natural philosophy in the ancient Greek world, especially in the Presocratics, Plato, and Aristotle. She focuses on the philosophical processes through which central concepts of metaphysics and natural philosophy, such as space or speed, arise in Greek antiquity. By showing that such concepts were originally spelt out in ways significantly different from the way they are today, she aims to make us aware both of the rich conceptual basis we often take for granted, as well as to sketch out possible alternative understandings. She is the author of The Concept of Motion in Ancient Greek Thought – Foundations in Logic, Method, and Mathematics (CUP 2020), and is currently writing a book on ancient notions of space. This podcast is an audio recording of Professor Sattler's talk - 'Paradoxes as Philosophical Method and their Zenonian Origins' - at the Aristotelian Society on 1 February 2021. The recording was produced by the Backdoor Broadcasting Company.
