The dialogue "Gorgias" is considered one of Plato's most important works among philosophers and philologists. The variety of topics addressed within it—including public rhetoric and dialectics, justice and injustice, wrongdoing and suffering from wrong, the useful and the harmful, the good and the pleasant, law and nature—should not obscure the fact that the question of ethical principles forms the core of the entire work. An extensive commentary is included, which elucidates the rhetorical and philosophical dimensions of the text.
