The Republic is a Socratic dialogue by Plato, written in approximately 360 BC. It is one of the most influential works of philosophy and political theory, and arguably Plato’s best known work. In it, Socrates and various other Athenians and foreigners discuss the meaning of justice and whether the just man is happier than the unjust man by constructing an imaginary city ruled by philosopher-kings. The dialogue also discusses the nature of the philosopher, Plato’s Theory of Forms, the conflict between philosophy and poetry, and the immortality of the soul
The Phaedo is acknowledged to be one of Plato’s masterpieces, showing him both as a philosopher and as a dramatist at the height of his powers. For its moving account of the execution of Socrates, the Phaedo ranks among the supreme literary achievements of antiquity. It is also a document crucial to the understanding of many ideas deeply ingrained in western culture, and provides one of the best introductions to Plato’s thought.
Crito is a short but important dialogue by the ancient Greek philosopher Plato. It is a conversation between Socrates and his wealthy friend Crito regarding justice (δικη), injustice (αδικια), and the appropriate response to injustice. Socrates thinks that injustice may not be answered with injustice, and refuses Crito’s offer to finance his escape from prison. This dialogue contains an ancient statement of the social contract theory of government.
