Refining Motivational Intellectualism: Plato’s Protagoras and Phaedo

Abstract

Abstract Refined intellectualism (RI) holds that although an agent’s actions always follow his rationally-produced choices of what is best, those choices can be influenced by non-rational motivational states. Through a contrast with the Protagoras, I argue that RI is not only clearly endorsed in the Phaedo but also central to the philosophical ethic defended in that dialogue. This result raises problems for prevailing developmentalist interpretations of Plato’s moral psychology.
