What are the two crucial conclusions reached at the end of Book One of Plato's Republic?

The two crucial conclusions are: 1) justice is not a craft but has a unique character, and 2) justice never harms; it only brings benefit.

How does Thrasymachus define justice and what is Socrates' disagreement?

Thrasymachus defines justice as the advantage of the stronger, which Socrates disagrees with, leading to a philosophical debate between them.

What are the three types of goods Glaucon discusses in Book Two of Plato's Republic?

The three types of goods Glaucon discusses are: 1) goods valued for themselves alone, like harmless pleasures; 2) goods valued for themselves and for their results, like knowledge or health; and 3) goods valued for their results but burdensome in themselves, like exercise or taking medicine.

Which category of good does Socrates believe justice belongs to, and why?

Socrates believes justice belongs to the second category, as it is valuable in itself and for its consequences, similar to good health or seeing.

What is Glaucon's Challenge and how does it relate to the common people's view of justice?

Glaucon's Challenge is a philosophical argument that questions whether justice is valuable in itself or only for its consequences. It relates to the common people's view by suggesting they might see justice as burdensome but necessary, valuing it only for its results.

What is the natural origin of justice according to Glaucon's story?

According to Glaucon's story, the natural origin of justice is an agreement among people who are too weak to dominate others, forming a truce to prevent victimization, as they realize the pain of suffering oppression outweighs the pleasure of oppressing the weaker.

What is the moral of Glaucon's story of the Ring of Gyges?

The moral of the Ring of Gyges story is to illustrate that people would choose injustice over justice if they could act without consequences, suggesting that the appearance of justice might be more valuable than actual justice for some.

📚 Introduction to Plato's Republic Book Two

Dr. Anadale introduces Book Two of Plato's Republic, continuing the philosophical discussion on the nature of justice initiated in Book One. The video outlines the structure of Book Two, which is divided into three parts: Glaucon's Challenge, the Political Metaphor, and the Guardians. It emphasizes the importance of the first third, Glaucon's Challenge, which includes a framework for the discussion and two key stories: the natural origin of justice and the Ring of Gyges. The framework introduces three types of goods, and Glaucon questions the intrinsic value of justice, contrasting it with the views of the common people. The challenge is to demonstrate the value of justice independent of its consequences, which sets the stage for the rest of the dialogue.

🔍 Glaucon's Challenge and the Ring of Gyges

In this section, Glaucon presents a challenge to Socrates, arguing that justice is a social contract among the weak to prevent domination by the strong. He suggests that people only practice justice because they lack the power to be unjust without consequence. To illustrate this, Glaucon tells the story of the Ring of Gyges, which explores the behavior of individuals with the power to act unjustly without repercussions. The story challenges the audience to consider whether justice is chosen for its own sake or merely for its rewards. Glaucon also sets up a comparison between the lives of a just person falsely perceived as unjust and an unjust person perceived as just, asking Socrates to prove that true justice leads to happiness regardless of reputation. Adeimantus then adds his own argument, suggesting that people praise justice for its reputational benefits, not its intrinsic value, and that the life of an unjust person with a just reputation is the most desirable.

Keywords

💡Justice

Justice is a central theme in Plato's 'Republic' and is defined in various ways throughout the dialogue. In the video, justice is initially discussed as not being a craft but having a unique character. It is also described as something that never harms and only brings benefit. The video explores different perspectives on justice, including whether it is a good in itself or merely a means to an end. The exploration of justice is crucial as it sets the stage for the dialogue in Book Two and the challenges posed by Glaucon and Adeimantus.

💡Socrates

Socrates is the main interlocutor in Plato's 'Republic' and is portrayed as seeking the true definition of justice. In the video, Socrates engages in dialogues to understand justice better, rejecting conventional definitions and arguing against Thrasymachus' view that justice is the advantage of the stronger. His method of questioning and his belief in the intrinsic value of justice are highlighted, showing his commitment to philosophical inquiry and the pursuit of truth.

💡Thrasymachus

Thrasymachus is a character in 'Republic' who introduces the idea that justice is the advantage of the stronger. This view is later challenged by Socrates and becomes a point of contention in the dialogue. The video mentions that Thrasymachus abandons the conversation, leaving Glaucon and Adeimantus to continue his argument, which is crucial as it sets up the challenges that Socrates must address in Book Two.

💡Glaucon

Glaucon is a brother of Adeimantus and a character in 'Republic' who takes up the challenge of defining justice after Thrasymachus leaves. In the video, Glaucon presents what he calls 'Glaucon's Challenge,' which includes the framework for discussing justice, the story of the natural origin of justice, and the story of the Ring of Gyges. His challenge to Socrates is to demonstrate the value of justice independent of its consequences, which is a key point of discussion in the video.

💡Goods

The concept of 'goods' is introduced by Glaucon as a framework for discussing justice. He categorizes goods into three types: those valued for themselves alone, those valued for themselves and their results, and those valued for their results but burdensome in themselves. This classification is used to question in which category justice belongs, which is a central point of debate in the video and relates to the nature and value of justice.

💡Natural Origin of Justice

The 'natural origin of justice' is a story told by Glaucon to explain how people came to agree on what justice is. According to the story, people realized that suffering injustice was worse than doing injustice and thus agreed not to harm each other, which they called 'justice.' This story is used to argue that justice is a second-best situation, chosen only when people are not strong enough to dominate others.

💡Ring of Gyges

The 'Ring of Gyges' is a story used by Glaucon to illustrate the difference between being just and seeming to be just. The story involves a ring that makes its wearer invisible, which allows a just person to act unjustly without consequence. The lesson Glaucon draws is that people would choose injustice if they could get away with it, suggesting that justice is pursued only for its rewards, not for its own sake.

💡Political Metaphor

The 'political metaphor' is a part of Socrates' response to Glaucon's and Adeimantus' challenges. It refers to the discussion of an ideal city's structure as a means to understand justice. The video mentions that Socrates will use this metaphor to address the challenges posed, indicating that the metaphor is a key tool in the philosophical exploration of justice.

💡Guardians

The term 'Guardians' refers to the class of individuals in the ideal city that Socrates discusses, who are responsible for protecting the city and its citizens. The video mentions the Guardians in the context of their character and education, which is part of Socrates' response to the challenges about justice. The Guardians are an important element in the construction of the ideal city and the understanding of justice within it.

💡Injustice

Injustice is the opposite of justice and is a key concept in the video as it is contrasted with justice throughout the dialogue. The video discusses the perceived benefits of injustice and the challenges in proving that justice is more desirable than injustice. The exploration of injustice is essential for understanding the arguments presented by Glaucon and Adeimantus and Socrates' responses to them.

Transcripts

Hello, I'm Dr. Anadale. I teach philosophy at Mount St. Mary's University in Emmitsburg Maryland.

This video is an introduction to Book Two of Plato's Republic.

In Book One, Socrates started the quest for the true definition of justice.

After considering and rejecting some conventional definitions, the conversation produced two crucial conclusions.

First: justice is not a craft like medicine or shipbuilding, but has a unique character.

And second: justice never harms; it only brings benefit.

Halfway through Book One Thrasymachus enters the conversation conversation and defines justice as the advantage of the stronger.

Socrates disagrees and they argue. At the beginning of Book Two, Thrasymachus abandons the conversation and two more speakers, Glaucon and Adeimantus, take over his position.

Book Two falls into three roughly equal parts, which I call Glaucon's Challenge, the Political Metaphor, and the Guardians, their character and education.

I will discuss each part separately. First, what I call Glaucon's Challenge. This is the first third of Book Two, up to approximately 368c.

Several very important things happen in this section so you should read these pages very carefully.

Glaucon's Challenge contains three important passages: the framework, giving three types of goods,

the story of the natural origin of justice and the story of the Ring of Gyges.

So we have a framework and two stories that make up Glaucon's challenge.

Book Two starts by giving a framework for the discussion to follow.

Glaucon says there are three kinds of goods: goods that are valued for themselves alone, things like harmless pleasures,

like playing a game simply because I enjoy it, not because I hope to get anything out of it.

Second, goods that are valued for themselves and for their results: things like knowing, or seeing, or being healthy.

These things are pleasant and good in themselves and they also make it possible for me to do other pleasant and good things.

And third, goods that are valued for their results but which are burdensome in themselves.

And these are things like exercise, or taking medicine, or doing physical labor in exchange for money.

No one would do these things unless they were somehow connected to some kind of external reward structure.

Glaucon asks Socrates which category justice belongs in; what type of good is it?

Socrates says he thinks it's in the second category: it's like good health or seeing; it's valuable in itself and valuable for its consequences.

Glaucon replies that the masses, the common people, would probably disagree.

They would put justice in category 3: they would say being just has good consequences but it's burdensome and difficult in itself

and nobody would do it unless they felt they had to.

Crucial to note here is that they differ not on the results of justice which they agree are beneficial.

They disagree on the question of whether justice is valuable in itself, in isolation from its practical effect on our lives.

Glaucon then takes up Thrasymachus' side of the argument, saying that he wants Socrates to demonstrate

the value of justice and injustice in the soul, independent of their consequences.

Glaucon insists that he doesn't believe what he is about to say about justice, but he wants to state a strong case

for Thrasymachus' point of view so that Socrates can defeat it.

It's worth pausing to note the value of this work by Glaucon.

It's valuable because if we had relied on Thrasymachus to carry his side of the argument we wouldn't learn anything,

because Thrasymachus got fed up and walked away. It's also giving us a very good example of the practice of stating an enemy's case

in the strongest possible form before attacking it. This is an example of the intellectual honesty and integrity of Socrates' method.

Glaucon then tells what he thinks the masses believe. This is his story of the natural origin of justice.

He says primitive people recognized that doing injustice was good and suffering injustice was bad.

So it feels good to beat up the people who are smaller than me, but it feels bad to get beat up by the people who are bigger and stronger than me.

Most people, being in the middle, experienced both sides of this: they were able to victimize others but they were

also the victims of people who are stronger than them. And they realized that the pain of suffering oppression

was greater than the pleasure they got from oppressing the weaker. So they banded together, all these primitive people,

and agreed among themselves that no one would victimize anyone else. And this is what they decided to call "justice."

Therefore justice, says Glaucon, is an agreement between people who are too weak to dominate everyone else.

It's something like a truce in the war of the strong against the weak, which has been called by all the people who know that they're not the strongest.

Some of you will recognize in this the basic idea behind social contract theory. The upshot of this story is that for each person

justice is always a second best situation. It is what I settle for instead of my best-case scenario, which

would be my being powerful enough to dominate everyone around me and this is why Glaucon says that people only do justice unwillingly.

That is, they are just only because they realize that they are not strong enough to get away with being unjust.

But if they could get away with it they certainly would choose injustice and domination as the better life in itself.

To illustrate this view of justice, Glaucon tells the story of the Ring of Gyges.

He considers the case of a just and an unjust person and what they would

each do if they had complete freedom of action to act exactly as they like with

no consequences for their reputation. My reading question for you is: summarize the Ring of Gyges story.

What lesson does Glaucon think it teaches about the difference between being just and seeming to be just?

After he tells the story, Glaucon compares the just life to the unjust life. To separate the benefits of reputation

from the benefits of actually being just or unjust, he's going to compare two extremes.

He's going to compare the just person whom everyone thinks is unjust to the unjust person whom everyone thinks is just.

So consider this the case of Mother Teresa in real life, but everybody thinks she's Hitler,

and on the other side Hitler in real life but everybody thinks he's Mother Teresa; he has that reputation.

If being just always makes one happy, and being unjust always makes one miserable, we would expect these two lives to still be happy and miserable.

So the challenge that Glaucon poses to Socrates is: compare these two extreme lives--the just life with a reputation for injustice,

and the unjust life with a reputation for justice--and prove to me that the just life is still preferable, is still happier

and is still the life more worthy of imitation for somebody who's trying to choose how to live their life.

At this point Glaucon's brother Adeimantus interrupts and gives his own defense of injustice, starting at 362d.

He points out that people who praise justice still seem to believe that injustice would be better for an individual.

People who praise justice, he says, really are only praising its reputation.

Injustice is "sweet and easy to acquire" and "the unjust person who has secured for himself a reputation for justice

lives the life of a god." That's the best life possible: the unjust life with a reputation for justice.

So Adeimantus puts this challenge to Socrates again slightly differently:

Show us, he says, how justice *by itself* makes a person happy, and show us how injustice *by itself* harms a person.

To respond to this challenge, Socrates is going to introduce the next stage of Book Two, which is the political metaphor.

He is going to consider the structure of an ideal city. I'll talk about that metaphor in a different video.

Thanks for watching today; goodbye.
