The society we have described can never grow into a reality or see the light of day, and there will be no end to the troubles of states, or indeed, my dear Glaucon, of humanity itself, till philosophers become rulers in this world, or till those we now call kings and rulers really and truly become philosophers, and political power and philosophy thus come into the same hands.

That's what education should be," I said, "the art of orientation. Educators should devise the simplest and most effective methods of turning minds around.

Reading Plato should be easy; understanding Plato can be difficult.
Here's something else I'd like your opinion about," I said. "If he went back underground and sat down again in the same spot, wouldn't the sudden transition from the sunlight mean that his eyes would be overwhelmed by darkness?" "Certainly," he replied. "Now, the process of adjustment would be quite long this time, and suppose that before his eyes had settled down and while he wasn't seeing well, he had once again to compete against those same old prisoners at identifying those shadows. Would he make a fool of himself? Wouldn't they say that he'd come back from his upward journey with his eyes ruined, and that it wasn't even worth trying to go up there? And would they -- if they could -- grab hold of anyone who tried to set them free and take them up there and kill him?

Imagine that the keeper of a huge, strong beast notices what makes it angry, what it desires, how it has to be approached and handled, the circumstances and the conditions under which it becomes particularly fierce or calm, what provokes its typical cries, and what tones of voice make it gentle or wild. Once he's spent enough time in the creature's company to acquire all this information, he calls it knowledge, forms it into a systematic branch of expertise, and starts to teach it, despite total ignorance, in fact, about which of the creature's attitudes and desires is commendable or deplorable, good or bad, moral or immoral. His usage of all these terms simply conforms to the great beast's attitudes, and he describes things as good or bad according to its likes and dislikes, and can't justify his usage of the terms any further, but describes as right and good the things which are merely indispensable, since he hasn't realised and can't explain to anyone else how vast a gulf there is between necessity and goodness.
It's not at all uncommon to find a person's desires compelling him to go against his reason, and to see him cursing himself and venting his passion on the source of the compulsion within him. It's as if there were two warring factions, with passion fighting on the side of reason. But I'm sure you won't claim that you had ever, in yourself or in anyone else, met a case of passion siding with his desires against the rational mind, when the rational mind prohibits resistance.

About the book

Written around 375 BCE, Plato's Republic is a Socratic dialogue in ten books in which Socrates and a group of Athenians investigate the meaning of justice and whether the just person is happier than the unjust one. The conversation begins in the Piraeus at the house of Cephalus and moves through competing definitions of justice, including Thrasymachus's claim that justice is merely the advantage of the stronger, before Socrates builds a far larger inquiry in response to a challenge from Glaucon and Adeimantus.

To understand justice in the soul, Socrates constructs an ideal city, the Kallipolis, arguing that the just city and the just soul share the same threefold structure: a rational part, a spirited part, and an appetitive part, mirrored in the city by rulers, warrior-guardians, and producers. Justice, on this account, is each part performing its proper role in harmony. The dialogue famously proposes that such a city can only flourish when philosophers become kings, since only they possess knowledge of the Forms and especially of the Form of the Good, illustrated through the Analogy of the Sun, the Divided Line, and the Allegory of the Cave.

The Republic is among the most influential works of philosophy and political theory ever written, shaping thinkers from Aristotle and Cicero to Thomas More, Hegel, and modern critics such as Karl Popper, who read the ideal city as totalitarian. It remains one of the most widely studied texts in universities and continues to frame debates about justice, education, the soul, and the best form of government.
