This book provides a collection of essays representing the state of the art in the research into argumentation in classical antiquity. It contains essays from leading and up and coming scholars on figures as diverse as Parmenides, Gorgias, Seneca, and Classical Chinese "wandering persuaders." The book includes contributions from specialists in the history of philosophy as well as specialists in contemporary argumentation theory, and stimulates the dialogue between scholars studying issues relating to argumentation theory in ancient philosophy and contemporary argumentation theorists. Furthermore, the book sets the direction for research into argumentation in antiquity by encouraging an engagement with a broader range of historical figures, and closer collaboration between contemporary concerns and the history of philosophy.
