"Tindale has done an admirable job of showing that Plato's ambivalent relationship with rhetoric doesn't end with middle dialogues such as the Gorgias and Phaedrus. He convincingly demonstrates that Plato not only continues to keep rhetoric in the forefront of his later dialogues, but also rehabilitates it and grants it a significant, albeit subordinate role to play." — John Harris, University of Alberta"This is a groundbreaking work that contributes in a masterful way not to just one field but several, such as Platonic philosophy, rhetoric, and theory of argumentation. Tindale also provides a link between classical philosophy and modern issues of informal logic. For the first time, the classical triad of logic, rhetoric, and dialectic central to informal logic and argumentation theory are applied to the complete oeuvre of Plato." — Manfred Kraus, University of Tübingen, Germany
