How does Socrates transition the discussion of justice?

By linking justice to knowledge and crafts.

What are the three components of a craft according to Socrates?

Knowledge, Purpose, and End.

How does Socrates relate justice to a craft?

Justice, like a craft, involves knowledge, purpose, and an intrinsic end—the promotion of "the Good.

Why does Socrates reject Polemarchus’ definition of justice?

true justice should promote the good of everyone, not just benefit friends and harm enemies.

What is Thrasymachus’ definition of justice?

Justice is the advantage of the stronger over the weaker.

What does Thrasymachus mean by "Might makes Right"?

Laws and justice serve the interests of rulers rather than being grounded in an objective moral good.

How does Thrasymachus view the function of justice in society?

As a tool that elevates the weak while restraining the strong, which he sees as unjust.

How does Socrates challenge Thrasymachus’ view of rulers?

By arguing that rulers, like practitioners of a craft, should serve the good of their subjects, not just themselves.

What contradiction does Socrates expose in Thrasymachus’ argument?

If rulers can make mistakes about their own advantage, then obeying them is not always just.

How does Socrates use the concept of a craft to refute Thrasymachus?

A true craft serves others rather than the practitioner, so ruling should benefit the ruled, not just the ruler.

Why does Socrates argue that complete injustice is self-defeating?

Even a band of thieves must practice some justice among themselves to function.

in the 3rd category, not for its value but for its repuatation and benefits

What challenge does Glaucon present to Socrates regarding justice?

Socrates must prove that justice is a good valued in itself, not just for its benefits.

What is the scenario Glaucon presents to test whether justice is truly valuable in itself?

He contrasts the life of a completely unjust man with a good reputation and a completely just man with a bad reputation.

What conclusion must Socrates reach for justice to be truly valuable?

That the truly just life is better than the unjust life, even if it results in suffering.

Why does Socrates turn to the idea of the city to explain justice?

Examining justice on a large scale (the city) helps to understand it on a smaller scale (the individual).

How does Socrates describe the natural formation of cities?

Cities form when individuals join together and specialize in different tasks, leading to trade, wealth, and the need for defense.

What is the role of division of labor in the formation of cities?

How does Socrates describe the purpose of education?
