01 • What is on the exam, and what should I bring?

Study Books I–III only. The professor's Sept 15 update replaces the older sheet's Book IV topics. You have 50 minutes to write an essay in class, with no books or notes. Bring a blue book and a pen or pencil. Source links are in this set's description.

02 • What main question connects Books I–III?

What is justice? And why choose to be just because justice itself is good, even when being unjust seems to pay more? These are two different tasks: defining justice and showing how justice helps the person who practices it.

03 • Cephalus: how do old age and money lead to justice? (330d–331b)

As death gets closer, Cephalus worries about wrongs he has done and debts he owes to people and gods. Money helps a decent person avoid cheating and pay those debts. He connects justice with being honest, paying what you owe, and meeting religious duties.

04 • Cephalus: what is justice, and what is the weapons problem? (331c–d)

His idea: tell the truth and return what you owe. Socrates' example: a friend lends you weapons, then loses his sanity and asks for them back. Returning them would follow the rule but would be wrong. So deciding what is just requires judgment about the situation; repayment is not always right.

05 • What does the weapons example prove—and not prove?

It shows that “always tell the truth and repay what you owe” cannot be a complete definition of justice. It does NOT give a full replacement definition. It also does not prove that every action with a good result is just.

06 • Polemarchus: what does “give people what they are owed” mean? (331e–332d)

Following the poet Simonides, he says it means help your friends and harm your enemies. This goes beyond returning borrowed things: what you should give someone depends on whether that person is your friend or enemy.

07 • Polemarchus: what if we choose the wrong friends? (334c–335a)

Socrates' objection: we can mistake bad people for friends and good people for enemies. The rule could then tell us to harm good people. Polemarchus changes it: help friends who really are good, and harm enemies who really are bad.

08 • Polemarchus: why does Socrates say harming enemies is wrong? (335b–e)

His steps: harming something makes it worse at its particular excellence. Harming a person makes that person worse in human virtue, which they identify here as justice. That would mean making the person more unjust. But justice cannot create its opposite. So a just person cannot make others unjust by harming them.

09 • How could you question Socrates' argument against harm?

Possible criticism: does every injury make someone a worse person? A punishment might hurt but improve someone's character. Keep three things separate: physical pain, losing an advantage, and becoming morally worse. The argument does not automatically answer every question about punishment or war.

10 • Polemarchus: why compare justice with skills like medicine? (332d–334b)

Socrates asks: what special benefit does justice provide, just as medicine provides health? The discussion makes justice look useful for guarding property when it is not being used. But someone skilled at guarding may also know how to steal it. Possible lesson: justice may not be a morally neutral skill that can be used for either good or bad ends.

11 • Thrasymachus: what does “the advantage of the stronger” mean? (338c–339a)

The “stronger” are the people who rule. They make laws that benefit themselves and call obeying those laws “just.” On this view, a subject is just by serving the rulers' interests, rather than following a standard of right and wrong independent of those rulers.

12 • Thrasymachus: what is the rulers' mistakes objection? (339b–341a)

Socrates: rulers sometimes order things that hurt themselves. If obeying rulers is just, justice would sometimes hurt the stronger. Thrasymachus replies: a ruler understood strictly as an expert does not make mistakes while correctly exercising that expertise.

13 • How does Socrates use skilled work to answer Thrasymachus? (341c–342e; 345e–347a)

A skill, properly understood, benefits what it cares for: medicine helps the patient. So genuine ruling should help the people being ruled. A ruler's pay comes from the separate activity of earning wages; getting paid is not the proper purpose of ruling itself.

14 • Why might the skilled-work argument fail to settle the debate?

Possible criticism: Socrates assumes that genuine ruling is like a skill aimed at helping the people it serves. Thrasymachus could reject that ideal picture. Keep two questions separate: what good rulers SHOULD do, and what powerful rulers ACTUALLY do.

15 • Thrasymachus: why compare rulers to shepherds? (343b–c)

Shepherds care for sheep, but they do it for their own or their owners' profit. So caring for someone does not necessarily mean putting that person's interests first. Thrasymachus applies this to rulers. Socrates answers by separating the work of genuine care from the separate goal of earning money.

16 • Thrasymachus: why does he think injustice pays better? (343c–344c)

He says just people lose out in business dealings, public duties, and how benefits are distributed. A person who gets away with injustice gains money and power; a tyrant is the biggest example. Justice helps someone else, while complete, successful injustice supposedly helps the person doing it most.

17 • Why would good people agree to rule? (347b–d)

Socrates says their main goal is not money or honor. They fear that, if they refuse, someone worse will rule them. Ruling is therefore a burden they accept to secure good government. This supports his claim that genuine ruling is not mainly about the ruler's personal gain.

18 • Book I, argument 1: how is a just person like an expert? (348b–351c)

A just person tries to outdo an unjust person, but not another just person. An expert similarly follows the right standard instead of trying to exceed another expert who is already doing it correctly. Socrates links justice with knowledge and goodness. Possible weakness: behaving similarly to an expert does not prove someone has moral knowledge.

19 • Book I, argument 2: why do even robbers need justice? (351c–352d)

If robbers constantly wrong one another, conflict and hatred stop them working together. Even their gang needs some internal justice. Socrates says injustice also divides a person against himself. His point: injustice undermines the ability of groups and individuals to act effectively.

20 • What is the weakness in the robbers argument?

A gang can cooperate fairly with its own members while robbing everyone else. So the argument shows why SOME justice inside a group is useful. It does not yet prove that being completely just toward everyone always benefits each person. This is a possible criticism, not Socrates' own conclusion.

21 • Book I, argument 3: how does justice supposedly make the soul happy? (352d–354a)

A thing does its job well when it has the excellence, or virtue, needed for that job. The soul's jobs include governing, thinking through choices, and living. If justice is its virtue, a just soul lives well and happily. The key gap: we still need support for the claim that justice really is the soul's virtue.

22 • Why does Book I end without a firm answer? (354b–c)

Socrates says they asked whether justice is a virtue and brings happiness before finding out what justice IS. Without a clear definition, those later claims lack a secure foundation. The arguments give possible answers, but the discussion is not finished.

23 • What are the three kinds of good things? (357b–d)

1. Good for their own sake: harmless enjoyment. 2. Good both in themselves and for their results: knowledge and health. 3. Unpleasant burdens accepted for their results: painful treatment or work done for pay.

24 • Which kind of good is justice? (358a)

Socrates: justice belongs in the best group—it is good in itself AND for its results. Popular opinion: justice is a burden worth accepting for rewards and a good reputation. The question is whether justice itself is good, not just whether it brings benefits others can see.

25 • Why do Glaucon and Adeimantus speak against justice?

They want a stronger defense of justice than Book I gave them. They make the case against justice as strong as possible so Socrates must answer it. They want to know what justice itself does for a person. Do not mistake these challenging speeches for simple statements that they personally support injustice.

26 • Glaucon: what are the three parts of his challenge? (358b–362c)

1. Explain how justice began as a compromise. 2. Argue that people are just unwillingly, using the ring story. 3. Compare a completely just life with a completely unjust one, after reversing their reputations. Each part asks whether justice is good in itself.

27 • Glaucon: how did justice begin? (358e–359b)

People like doing wrong without punishment, but being helpless victims is worse. Most cannot guarantee that they will always be the winner and never the victim. So they agree not to wrong one another. Laws and shared rules grow from this compromise, made because people are vulnerable.

28 • Glaucon: what does the Ring of Gyges test? (359c–360d)

The ring makes someone invisible, letting them do wrong without being caught or punished. Glaucon claims both just and unjust people would use that power for wrongdoing. This suggests fear of consequences keeps people in line. But it is an imagined test, not observed proof of what everyone would do.

29 • Glaucon: why give the just man a bad reputation? (360e–362c)

Make the completely unjust man LOOK just, so he gets justice's rewards. Make the completely just man LOOK unjust, so he gets disgrace and punishment. This separates actually being just from merely appearing just. Is justice still worth choosing when its usual rewards are taken away?

30 • What possible inconsistency is in Glaucon's speech?

He says nobody chooses justice willingly, but then imagines a completely just person who stays just despite suffering. That seems to challenge his claim about everybody. Be careful: the person is part of an imagined comparison, and Glaucon is presenting an argument he wants Socrates to answer.

31 • Adeimantus: what is wrong with the usual praise of justice? (362d–367e)

Parents, teachers, and poets praise the reputation and rewards justice brings: honor, wealth, good marriage prospects, and rewards from the gods. This gives people reasons to LOOK just. It does not explain why actually being just is good for their soul.

32 • Adeimantus: what is the problem with sacrifices buying forgiveness?

The stories suggest that injustice brings profit and offerings or rituals can remove divine punishment. A clever person might then think: “I can do wrong, keep the gains, and pay to escape the consequences.” Justice becomes less attractive if both people's opinions and the gods' punishment can be managed this way.

33 • How do Glaucon and Adeimantus differ?

Glaucon tests personal advantage through the ring and the two extreme lives. Adeimantus examines what people are taught and why they praise justice for rewards. Both want to know what justice and injustice themselves do inside a person, apart from reputation and rewards.

34 • Why does Socrates build a city in speech? (368c–369a)

Justice might be easier to spot in something large, a city, than in one person—like reading large letters before small ones. Building an imagined city through discussion may reveal where justice comes from, then help find it in a person. He is creating a model to investigate, not founding a real city.

35 • What is useful—and risky—about comparing a city with a person?

The city makes roles, cooperation, and conflict easier to see. But Socrates still has to show that justice works in the same relevant way in a city and in a person. A useful comparison is not automatically proof. For this exam, support your answer with Books I–III.

36 • Why do cities form, and why divide up the work? (369b–370c)

Nobody can meet all their needs alone: people need food, housing, clothing, and other services. They join together to exchange what they make. People have different natural abilities, and work goes better when one person focuses on a suitable task and does it at the right time.

37 • What is life like in the first, healthy city? (372a–d)

People do necessary jobs, eat simple food, enjoy modest comforts and family life, and sing to the gods. They limit population growth to what their resources can support. They live peacefully within their means. Socrates calls this healthy; Glaucon insults it as a “city of sows.”

38 • Why is justice hard to find in the first city? (371e–372a)

Adeimantus guesses that justice and injustice arise in citizens' dealings with one another. The city shows people cooperating, but no exact definition of justice has appeared. Possible criticism: naming a place where fairness can happen does not explain what fairness is.

39 • Why does Glaucon dislike the city of sows? (372d–e)

He wants the normal comforts of civilized life, including couches, tables, and richer food. For him, merely meeting basic needs is not a good enough life. Possible interpretation: this continues his earlier interest in the attraction of having more.

40 • How does luxury lead to war and guardians? (373a–374e)

More desires → more jobs and resources needed → more land needed → taking neighbors' land → war → a need for specially trained soldiers, or guardians. Limit: this model does not prove that a modest city could never be attacked by an aggressive neighbor.

41 • What opposite qualities must guardians have? (374e–376c)

They need strength, speed, courage, and spiritedness—a fierce, fighting spirit—toward enemies. But toward their own people, they must be gentle and eager to learn. The goal is powerful defenders who protect citizens instead of turning against them.

42 • Why compare guardians to dogs and philosophers? (375a–376c)

A good dog is fierce toward strangers but gentle toward people it knows. Socrates connects this use of knowledge with a love of learning, or philosophy. Possible criticism: knowing someone is familiar does not mean knowing they are good. The comparison suggests these qualities can coexist; it does not prove full philosophical judgment.

43 • What is the goal of the guardians' early education? (376e–377c)

“Music” here includes poetry and stories, alongside physical training, or gymnastics. These shape character as well as abilities. Children absorb stories before they can judge them carefully. Their education must therefore build courage, moderation or self-control, respect for the gods, and loyalty to the city.

44 • What should stories teach about the gods? (377e–383c)

God is good and causes good, not evil. Gods should not be shown doing shameful things or fighting one another. Because they are perfect, they do not change into something worse. They do not deceive people. Socrates argues that these claims are true and uses them to guide good education.

45 • Why remove scary stories about Hades? (386a–387c)

If guardians think death is the worst thing possible, they may choose defeat or slavery to avoid it. Removing frightening stories about the afterlife is meant to build courage. Possible criticism: does hiding frightening possibilities create real courage, or courage that depends on a carefully controlled story about death?

46 • Why is Achilles a bad example for guardians? (387d–391c)

An admired hero can make his behavior seem acceptable to young people. Achilles shows extreme grief, anger, greed, cruelty, and disrespect toward gods. Examples: his uncontrolled mourning for Patroclus and abuse of Hector's body. Socrates wants courage and strength joined with self-control, not heroism without restraint.

47 • What should replace uncontrolled grief and laughter? (387d–390d)

Stories should model enduring hardship, acting with moderation, obeying proper authority, and controlling pleasure and emotion. Too much laughter also shows a loss of self-control. The goal is disciplined character—not simply removing every feeling.

48 • When does Socrates allow lying? (382a–d; 389b–d)

He separates being mistaken or ignorant in your soul from speaking a falsehood that may be useful. Rulers may tell lies to enemies or citizens for the city's good, like giving medicine. This does not allow lying for private gain or give ordinary citizens permission to deceive rulers.

49 • How are rulers chosen, and who are the auxiliaries? (412b–414b)

Choose able guardians who keep caring about the city's good even when tested by fear, hardship, pleasure, or deception. The best become rulers—the guardians in the strict sense. Auxiliaries are their military helpers: they support the rulers and defend the city.

50 • Noble lie, part 1: what is the earthborn story for? (414b–415a)

Citizens are told that their upbringing was a dream: they were really formed beneath the earth. Their homeland is their mother, and other citizens are their siblings. The story aims to make them united, attached to their land, and willing to defend it.

51 • Noble lie, part 2: what does the metals story mean? (415a–c)

Gold in the soul fits rulers; silver fits auxiliaries; bronze or iron fits producers. The story justifies different jobs by different natural abilities. Children may have a different metal from their parents and must move up or down accordingly. So the roles are not fixed only by family background.

52 • Why tell guardians they already have divine gold and silver? (416e–417a)

Their souls supposedly already contain gold and silver from the gods. Ordinary precious metals would corrupt that divine gift. This story supports the rule against their owning monetary wealth and helps keep them devoted to the city's good.

53 • What property rules apply to guardians, and why? (416d–417b)

They may have necessities, but not private wealth, gold or silver, or private storage others cannot enter. They live and eat together, supported by the city. The aim is to stop armed protectors becoming rich masters who put themselves first. These rules target guardians, not every citizen.

54 • How does the noble lie create a problem about truth?

Education rejects false stories that harm character, yet allows false stories meant to help the city. Possible questions: can rulers teach justice through deception? Who decides what benefits the city? Before judging the risks, explain the public good each story is meant to serve.

55 • Practice essay: compare Book I's definitions of justice

Outline: 1. Make a claim about the limits of ordinary rules of justice. 2. Explain Cephalus and the weapons example. 3. Explain Polemarchus, mistaken friends, and the argument against harm. 4. Explain Thrasymachus, rulers' mistakes, and the skilled-work reply. 5. Explain why rejecting these definitions has not yet given a secure replacement. Practice only—not the actual exam question.

56 • Practice essay: does Socrates defeat Thrasymachus?

Explain TWO claims: Thrasymachus' definition of justice and his claim that injustice pays. Keep the skilled-work response separate from Socrates' three arguments that justice is good. Explain the cooperation argument and the objection about robbers. End with Book I's uncertainty at 354b–c. Give a judgment that recognizes both strengths and limits.

57 • Practice essay: why does Book II reopen the debate?

Start with Book I's missing definition. Explain the kinds of goods, Glaucon's agreement not to harm one another, the ring, and the reversed reputations. Contrast Adeimantus' attack on ordinary praise and divine rewards. End with their shared demand: show what justice does to the soul, apart from reputation.

58 • Practice essay: why build a city, then educate it?

Explain how the “larger letters” comparison is meant to reveal justice in a person. Trace needs → divided work → healthy city → Glaucon's luxury → war → guardians. Explain why military power needs education and limits. Then assess whether the model captures human desires and establishes the city–person comparison.

59 • Practice essay: how should guardians be trained and controlled?

Connect their fierce-but-gentle nature to poetry, teaching about gods, death, Achilles, and self-control. Explain how rulers are chosen, the separate purpose of each founding story, and the property limits. Use specific examples to assess a tension: truth versus the city's benefit, or strength versus gentleness.

60 • How can I organize a 50-minute essay?

Suggested plan: 5 minutes to identify every part of the question and outline; 40 to write; 5 to check that the answer is complete and clear. Build each point as claim → explain the reasoning → give a textual example → assess it. Do not replace reasoning with lists of names or memorized conclusions.
