"The Republic" is a Socratic dialogue by Plato, written around 375 BC. It falls under the genre of philosophy and political theory.
In this work, Socrates and other Athenians explore the meaning of justice, examining whether a just person is happier than an unjust one. This leads to a discussion of different regimes and the proposal of Kallipolis, a utopian city-state ruled by philosopher-kings. The dialogue also touches on themes of ethics, the immortality of the soul, the theory of forms, love, and the roles of philosophers and poetry in society.
"The Republic" is considered Plato's most influential work and a cornerstone of Western philosophy. Academics and students voted it the greatest philosophical text ever written in a 2001 survey. While there are no direct film or TV adaptations of "The Republic," the 1971 film Socrates alludes to the work. The dialogue is divided into ten books and translations vary in page count, with some editions containing around 480 pages.
