Republic

O livro República do antigo filósofo Platão

The Republic (Greek: Πολιτεία, Politeia; Latin: Res Publica) is a Socratic dialogue, written by Plato around 380 BC, concerning justice (δικαιοσύνη), the order and character of the just city-state, and the just man. It is Plato's best-known work, and has proven to be one of the world's most influential works of philosophy and political theory, both intellectually and historically.

In the dialogue, Socrates discusses with various Athenians and foreigners about the meaning of justice and whether the just man is happier than the unjust man. They consider the natures of existing regimes and then propose a series of different, hypothetical cities in comparison, culminating in Kallipolis (Καλλίπολις), a city-state ruled by a philosopher king. They also discuss the theory of forms, the immortality of the soul, and the role of the philosopher and of poetry in society. The dialog's setting seems to be during the Peloponnesian War.
