Chapter 3

Plato vs. the Sophists: Rhetoric on Trial


Chapter Overview

Plato recognized the power of persuasive language, particularly when employed by a trained practitioner of rhetoric. He also saw a great danger in this power. Rhetoric in the service of personal motives, and appealing to an ignorant public, would lead a society to ruin. In Gorgias, he reveals the problems inherent in the practice of rhetoric when it is not joined to wisdom and a true knowledge of justice. Plato asked his readers to consider what constitutes “the good life.” Rhetoric can serve good or evil goals. Plato suggests in Phaedrus, there can be a true art of rhetoric. It would consist of a thorough knowledge of the different types of human souls, as well as a thorough knowledge of how to make arguments that would appeal to each type of soul.
