The Republic by Plato - The Republic is Plato's most famous work and one of the seminal texts of Western philosophy and politics. The characters in this Socratic dialogue - including Socrates himself - discuss whether the just or unjust man is happier.
Plato described in his Republic the need for the elite to maintain certain myths, which he called "noble lies" (gennaion pseudos) in order to protect social harmony. These could include, for example, religion.
