What justice actually is
Four definitions fail in the first book alone.
- What do I actually owe other people?
- Is it ever right to break a rule?
- What does fairness mean when everyone claims it?

The Republic by Plato
It begins with a simple question — what is justice? — and the first four answers all collapse under questioning within a few pages. That pattern is the book.
Somewhere in the middle a character called Glaucon raises the hardest objection in moral philosophy: give a man a ring that makes him invisible and he will do whatever he likes, so isn't everyone only good because they're being watched? The remaining eight books are Socrates trying to answer him.
Along the way it builds an imaginary city, argues that philosophers should rule it, proposes abolishing the family, and produces the allegory of the cave — the image of prisoners who prefer shadows to daylight, and would kill the person who tried to free them.

The ring of Gyges — the hardest question in the book.
Prisoners who prefer shadows, and resent being freed.
His answer was philosophers, and he knew how that sounded.

The Republic is a Socratic dialogue in ten books, written by Plato around 375 BC and set in the Athens of his teacher Socrates, who executed the arguments and was executed by the city in 399 BC.
Its stated subject is justice — what it is, and whether a just life is better than an unjust one even when injustice pays. To answer it, Socrates builds a city in speech, on the theory that justice will be easier to see written large in a state than small in a person.
It is also the origin of a great deal else: the theory of Forms, the tripartite soul, the allegory of the cave, the philosopher-king, and a censorship regime for poetry that has troubled admirers for two thousand years. Karl Popper called it totalitarian. Others read the ideal city as a deliberate impossibility, constructed to say something about the individual instead.
In its words
The beginning is the most important part of the work.
Behold! human beings living in an underground den.
The chief penalty is to be governed by someone worse than yourself, if a man will not himself hold office and rule.
Necessity, who is the mother of invention.
