Rachel Barney is Professor of Classics and Professor of Philosophy at the University of Toronto. She received her PhD at Princeton and has taught at the University of Ottawa, Harvard, and the University of Chicago. She has worked widely across ancient philosophy, from the sophists to the Neoplatonists, though her primary focus is on Plato. In this episode, Robinson and Rachel discuss the sophists, beginning with just who they were and why they have been so maligned in contemporary discourse—even the word sophist today has pejorative connotations—and continuing through some of their most important thinkers, like Gorgias and Protagoras. Check out Rachel’s last book, Plato and the Divided Self (Cambridge University Press, 2012).
