Gorgias is a Socratic dialogue written by Plato around 380 BC. The dialogue depicts a conversation between Socrates and a small group of sophists (and other guests) at a dinner gathering, Socrates debates with the sophist seeking the true definition of rhetoric, attempting to pinpoint the essence of rhetoric and unveil the flaws of the sophistic oratory popular in Athens at this time. The art of persuasion was widely considered necessary for political and legal advantage in classical Athens, and rhetoricians promoted themselves as teachers of this fundamental skill. Some, like Gorgias, were foreigners attracted to Athens because of its reputation for intellectual and cultural sophistication. In the Gorgias, Socrates argues that philosophy is an art, whereas rhetoric is a skill based on mere experience. To Socrates, most rhetoric in practice is merely flattery. In order to use rhetoric for good, rhetoric cannot exist alone; it must depend on philosophy to guide its morality. Socrates, therefore, believes that morality is not inherent in rhetoric and that without philosophy, rhetoric is simply used to persuade for personal gain. Socrates suggests that he is one of the few (but not only) Athenians to practice true politics (521d).
