The Republic (Ancient Greek: Πολιτεία, romanized: Politeia; Latin: De Republica)^[1] is a Socratic dialogue, authored by Plato around 375 BC, concerning justice (dikaiosúnē), the order and character of the just city-state, and the just man.^[2] It is Plato's best-known work, and one of the world's most influential works of philosophy and political theory, both intellectually and historically.^[3][4]

In the dialogue, Socrates discusses with various Athenians and foreigners the meaning of justice and whether the just man is happier than the unjust man.^[5] He considers the natures of existing regimes and then proposes a series of hypothetical cities in comparison, culminating in Kallipolis (Καλλίπολις), a utopian city-state ruled by a class of philosopher-kings. They also discuss ageing, love, theory of forms, the immortality of the soul, and the role of the philosopher and of poetry in society.^[6] The dialogue's setting seems to be the time of the Peloponnesian War.^[7]

The Republic is generally placed in the middle period of Plato's dialogues. However, the distinction of this group from the early dialogues is not as clear as the distinction of the late dialogues from all the others. Nonetheless, Ritter, Arnim, and Baron—with their separate methodologies—all agreed that the Republic was well distinguished, along with Parmenides, Phaedrus and Theaetetus.^[8]

However, the first book of the Republic, which shares many features with earlier dialogues, is thought to have originally been written as a separate work, and then the remaining books were conjoined to it, perhaps with modifications to the original of the first book.^[8]

While visiting Athens's port, Piraeus, with Glaucon, Socrates is invited to join Polemarchus for a dinner and festival. They eventually end up at Polemarchus' house where Socrates encounters Polemarchus' father Cephalus.

In his first philosophical conversation with the group members, Socrates gets into a conversation with Cephalus. The first real philosophical question posed by Plato in the book is when Socrates asks "is life painful at that age, or what report do you make of it?"^[9] when speaking to the aged Cephalus.

Cephalus answers by saying that many are unhappy about old age because they miss their youth, but he finds that "old age brings us profound repose and freedom from this and other passions. When the appetites have abated, and their force is diminished, the description of Sophocles is perfectly realized. It is like being delivered from a multitude of furious masters."^[9] The repose gives him time to dedicate himself to sacrifices and justice so that he is prepared for the afterlife.

Socrates then asks his interlocutors for a definition of justice. Three are suggested:

• Cephalus: To give each what is owed to them (331c)
• Polemarchus: To give to each what is appropriate to him (332c)
• Thrasymachus: What is advantageous for the stronger (338c)

Socrates refutes each definition in turn:

• One may owe it to someone to return them a knife one has borrowed, but if he has since gone mad and would only harm himself with it, returning the knife would not be just.
• Polemarchus suggests that what is appropriate is to do good to friends and bad to enemies, but harming someone tends to make them unjust, and so on his definition, justice would tend to create injustice.
• If it is just to do what rulers (the stronger) say and rulers make mistakes about their advantage, then it is just to do what is disadvantageous for the stronger.

Thrasymachus then responds to this refutation by claiming that insofar as the stronger make mistakes, they are not in that regard the stronger. Socrates refutes Thrasymachus with a further argument: Crafts aim at the good of their object, and therefore to rule is for the benefit of the ruled and not the ruler.

At this point, Thrasymachus claims that the unjust person is wiser than the just person, and Socrates gives three arguments refuting Thrasymachus. However, Thrasymachus ceases to engage actively with Socrates's arguments, and Socrates himself seems to think that his arguments are inadequate, since he has not offered any definition of justice. The first book ends in aporia concerning the essence of justice.

Glaucon and Adeimantus are unsatisfied with Socrates's defense of justice. They ask Socrates to defend justice against an alternative view that they attribute to many. According to this view, the origin of justice is in social contracts. Everyone would prefer to get away with harm to others without suffering it themselves, but since they cannot, they agree not to do harm to others so as not to suffer it themselves. Moreover, according to this view, all those who practice justice do so unwillingly and out of fear of punishment, and the life of the unpunished unjust man is far more blessed than that of the just man. Glaucon would like Socrates to prove that justice is not only desirable for its consequences, but also for its own sake. To demonstrate the problem, he tells the story of Gyges, who – with the help of a ring that turns him invisible – achieves great advantages for himself by committing injustices. Many think that anyone would and should use the ring as Gyges did if they had it. Glaucon uses this argument to challenge Socrates to defend the position that the just life is better than the unjust life.

Adeimantus supplements Glaucon's speech with further arguments. He suggests that the unjust should not fear divine judgement, since the very poets who wrote about such judgement also wrote that the gods would grant forgiveness to those who made religious sacrifice.

Socrates suggests that they use the city as an image to seek how justice comes to be in the soul of an individual. After attributing the origin of society to the individual not being self-sufficient and having many needs which he cannot supply himself, Socrates first describes a "healthy state" made up of producers who make enough for a modest subsistence, but Glaucon considers this hardly different than "a city of pigs." Socrates then goes on to describe the luxurious city, which he calls "a fevered state".^[10] Acquiring and defending these luxuries requires a guardian class to wage wars.

They then explore how to obtain guardians who will not become tyrants to the people they guard. Socrates proposes that they solve the problem with an education from their early years. He then prescribes the necessary education, beginning with the kind of stories that are appropriate for training guardians. They conclude that stories that ascribe evil to the gods or heroes or portray the afterlife as bad are untrue and should not be taught. They also decide to regulate narrative and musical style so as to encourage the four cardinal virtues: wisdom, courage, justice and temperance. Socrates avers that beautiful style and morally good style are the same. In proposing their program of censored education, they are repurifying the luxurious or feverish city. Socrates counters the objection that people raised in censorship will be too naive to judge concerning vice by arguing that adults can learn about vice once their character has been formed; before that, they are too impressionable to encounter vice without danger.

They suggest that the second part of the guardians' education should be in gymnastics. With physical training they will be able to live without needing frequent medical attention: physical training will help prevent illness and weakness. Socrates claims that any illness requiring constant medical attention is too unhealthy to be worth living. By analogy, any society that requires constant litigation is too unhealthy to be worth maintaining.

Socrates asserts that both male and female guardians be given the same education, that all wives and children be shared, and that they be prohibited from owning private property so that guardians will not become possessive and keep their focus on the good of the whole city. He adds a third class distinction between auxiliaries (rank and file soldiers) and guardians (the leaders who rule the city).

In the fictional tale known as the myth or parable of the metals, Socrates presents the Noble Lie (γενναῖον ψεῦδος, gennaion pseudos), to convince everyone in the city to perform their social role. All are born from the womb of their mother country, so that all are siblings, but their natures are different, each containing either gold (guardians), silver (auxiliaries), or bronze or iron (producers). If anyone with a bronze or iron nature rules the city, it will be destroyed. Socrates claims that if the people believed "this myth...[it] would have a good effect, making them more inclined to care for the state and one another."^[11] Socrates claims the city will be happiest if each citizen engages in the occupation that suits them best. If the city as a whole is happy, then individuals are happy.

In the physical education and diet of the guardians, the emphasis is on moderation, since both poverty and excessive wealth will corrupt them (422a1). He argues that a city without wealth can defend itself successfully against wealthy aggressors. Socrates says that it is pointless to worry over specific laws, like those pertaining to contracts, since proper education ensures lawful behavior, and poor education causes lawlessness (425a–425c).^[12]

Socrates proceeds to search for wisdom, courage, and temperance in the city, on the grounds that justice will be easier to discern in what remains (427e). They find wisdom among the guardian rulers, courage among the guardian warriors (or auxiliaries), temperance among all classes of the city in agreeing about who should rule and who should be ruled. Finally, Socrates defines justice in the city as the state in which each class performs only its own work, not meddling in the work of the other classes (433b).

The virtues discovered in the city are then sought in the individual soul. For this purpose, Socrates creates an analogy between the parts of the city and the soul (the city–soul analogy).^[13] He argues that psychological conflict points to a divided soul, since a completely unified soul could not behave in opposite ways towards the same object, at the same time, and in the same respect (436b).^[14] He gives examples of possible conflicts between the rational, spirited, and appetitive parts of the soul, corresponding to the rulers, auxiliaries, and producing classes in the city.^[15] Having established the tripartite soul, Socrates defines the virtues of the individual. A person is wise if he is ruled by the part of the soul that knows "what is beneficial for each part and for the whole," courageous if his spirited part "preserves in the midst of pleasures and pains" the decisions reached by the rational part, and temperate if the three parts agree that the rational part lead (442c–d).^[16] They are just if each part of the soul attends to its function and not the function of another. It follows from this definition that one cannot be just if one does not have the other cardinal virtues.^[14] In this regard, Plato can be seen as a progenitor of the concept of 'social structures'.

Socrates, having to his satisfaction defined the just constitution of both city and psyche, moves to elaborate upon the four unjust constitutions of these. Adeimantus and Polemarchus interrupt, asking Socrates instead first to explain how the sharing of wives and children in the guardian class is to be defined and legislated, a theme first touched on in Book III. Socrates is overwhelmed at their request, categorizing it as three "waves" of attack against which his reasoning must stand firm. These three waves challenge Socrates' claims that

• both male and female guardians ought to receive the same education
• human reproduction ought to be regulated by the state and all offspring should be ignorant of their actual biological parents
• such a city and its corresponding philosopher-king could actually come to be in the real world.

In Books V–VII the abolition of riches among the guardian class (not unlike Max Weber's bureaucracy) leads controversially to the abandonment of the typical family, and as such no child may know his or her parents and the parents may not know their own children. Socrates tells a tale which is the "allegory of the good government". The rulers assemble couples for reproduction, based on breeding criteria. Thus, stable population is achieved through eugenics and social cohesion is projected to be high because familial links are extended towards everyone in the city. Also the education of the youth is such that they are taught of only works of writing that encourage them to improve themselves for the state's good, and envision (the) god(s) as entirely good, just, and the author(s) of only that which is good.

Socrates' argument is that in the ideal city, a true philosopher with understanding of forms will facilitate the harmonious co-operation of all the citizens of the city—the governance of a city-state is likened to the command of a ship, the Ship of State. This philosopher-king must be intelligent, reliable, and willing to lead a simple life. However, these qualities are rarely manifested on their own, and so they must be encouraged through education and the study of the Good.

The Allegory of the Cave primarily depicts Plato's distinction between the world of appearances and the 'real' world of the Forms.^[17] Just as visible objects must be illuminated in order to be seen, so must also be true of objects of knowledge if light is cast on them.

Plato imagines a group of people who have lived their entire lives as prisoners, chained to the wall of a cave in the subterranean so they are unable to see the outside world behind them. However a constant flame illuminates various moving objects outside, which are silhouetted on the wall of the cave visible to the prisoners. These prisoners, through having no other experience of reality, ascribe forms to these shadows such as either "dog" or "cat". Plato then goes on to explain how the philosopher is akin to a prisoner who is freed from the cave. The prisoner is initially blinded by the light, but when he adjusts to the brightness he sees the fire and the statues and how they caused the images witnessed inside the cave. He sees that the fire and statues in the cave were just copies of the real objects; merely imitations. This is analogous to the Forms. What we see from day to day are merely appearances, reflections of the Forms. The philosopher, however, will not be deceived by the shadows and will hence be able to see the 'real' world, the world above that of appearances; the philosopher will gain knowledge of things in themselves. At the end of this allegory, Plato asserts that it is the philosopher's burden to reenter the cave. Those who have seen the ideal world, he says, have the duty to educate those in the material world. Since the philosopher recognizes what is truly good only he is fit to rule society according to Plato.

In Books VIII–IX stand Plato's criticism of the forms of government. Plato categorized governments into five types of regimes: aristocracy, timocracy, oligarchy, democracy, and tyranny.

The starting point is an imagined, alternate aristocracy (ruled by a philosopher-king); a just government ruled by a philosopher king, dominated by the wisdom-loving element. Aristocracy degenerates into timocracy when, due to miscalculation on the part of its governing class, the next generation includes persons of an inferior nature, inclined not just to cultivating virtues but also producing wealth. In a timocracy, governors will apply great effort in gymnastics and the arts of war, as well as the virtue that pertains to them, that of courage. As the emphasis on honor is compromised by wealth accumulation, it is replaced by oligarchy. The oligarchic government is dominated by the desiring element, in which the rich are the ruling class. Oligarchs do, however, value at least one virtue, that of temperance and moderation—not out of an ethical principle or spiritual concern, but because by dominating wasteful tendencies they succeed in accumulating money.

As this socioeconomic divide grows, so do tensions between social classes. From the conflicts arising out of such tensions, the poor majority overthrow the wealthy minority, and democracy replaces the oligarchy preceding it. In democracy, the lower class grows bigger and bigger. The populism of the democratic government leads to mob rule, fueled by fear of oligarchy, which a clever demagogue can exploit to take power and establish tyranny where no one has discipline and society exists in chaos. In a tyrannical government, the city is enslaved to the tyrant, who uses his guards to remove the best social elements and individuals from the city to retain power (since they pose a threat), while leaving the worst. He will also provoke warfare to consolidate his position as leader. In this way, tyranny is the most unjust regime of all.

In parallel to this, Socrates considers the individual or soul that corresponds to each of these regimes. He describes how an aristocrat may become weak or detached from political and material affluence, and how his son will respond to this by becoming overly ambitious. The timocrat in turn may be defeated by the courts or vested interests; his son responds by accumulating wealth in order to gain power in society and defend himself against the same predicament, thereby becoming an oligarch. The oligarch's son will grow up with wealth without having to practice thrift or stinginess, and will be tempted and overwhelmed by his desires,^[18] so that he becomes democratic, valuing freedom above all.^[18] The democratic man is torn between tyrannical passions and oligarchic discipline, and ends up in the middle ground: valuing all desires, both good and bad. The tyrant will be tempted in the same way as the democrat, but without an upbringing in discipline or moderation to restrain him. Therefore, his most base desires and wildest passions overwhelm him, and he becomes driven by lust, using force and fraud to take whatever he wants. The tyrant is both a slave to his lusts, and a master to whomever he can enslave. Socrates points out the human tendency to be corrupted by power leads down the road to timocracy, oligarchy, democracy and tyranny. From this, he concludes that ruling should be left to philosophers, who are the most just and therefore least susceptible to corruption. This "good city" is depicted as being governed by philosopher-kings; disinterested persons who rule not for their personal enjoyment but for the good of the city-state (polis). The philosophers have seen the "Forms" and therefore know what is good. They understand the corrupting effect of greed and own no property and receive no salary. The philosopher-kings also live in sober communism, eating and sleeping together among themselves.

Concluding a theme brought up most explicitly in the Analogies of the Sun and Divided Line in Book VI, Socrates finally rejects any form of imitative art and concludes that such artists have no place in the just city. He continues on to argue for the immortality of the psyche and espouses a theory of reincarnation. He finishes by detailing the rewards of being just, both in this life and the next. Artists create things but they are only different copies of the idea of the original. "And whenever any one informs us that he has found a man who knows all the arts, and all things else that anybody knows, and every single thing with a higher degree of accuracy than any other man—whoever tells us this, I think that we can only imagine to be a simple creature who is likely to have been deceived by some wizard or actor whom he met, and whom he thought all-knowing, because he himself was unable to analyze the nature of knowledge and ignorance and imitation."^[19]

And the same object appears straight when looked at out of the water, and crooked when in the water; and the concave becomes convex, owing to the illusion about colours to which the sight is liable. Thus every sort of confusion is revealed within us; and this is that weakness of the human mind on which the art of conjuring and deceiving by light and shadow and other ingenious devices imposes, having an effect upon us like magic.^[19]

He speaks about illusions and confusion. Things can look very similar, but be different in reality. Because we are human, at times we cannot tell the difference between the two.

And does not the same hold also of the ridiculous? There are jests which you would be ashamed to make yourself, and yet on the comic stage, or indeed in private, when you hear them, you are greatly amused by them, and are not at all disgusted at their unseemliness—the case of pity is repeated—there is a principle in human nature which is disposed to raise a laugh, and this which you once restrained by reason, because you were afraid of being thought a buffoon, is now let out again; and having stimulated the risible faculty at the theatre, you are betrayed unconsciously to yourself into playing the comic poet at home.

With all of us, we may approve of something, as long we are not directly involved with it. If we joke about it, we are supporting it.

Quite true, he said. And the same may be said of lust and anger and all the other affections, of desire and pain and pleasure, which are held to be inseparable from every action—in all of them poetry feeds and waters the passions instead of drying them up; she lets them rule, although they ought to be controlled, if mankind are ever to increase in happiness and virtue.^[19]

Sometimes we let our passions rule our actions or way of thinking, although they should be controlled, so that we can increase our happiness.

Aristotle systematises many of Plato's analyses in his Politics, and criticizes the propositions of several political philosophers for the ideal city-state.

Zeno of Citium, the founder of Stoicism, wrote his version of an ideal society, Zeno's Republic, in opposition to Plato's Republic.^[20] Zeno's Republic was controversial and was viewed with some embarrassment by some of the later Stoics due to its defenses of free love, incest, and cannibalism and due to its opposition to ordinary education and the building of temples, law-courts, and gymnasia.

The English title of Plato's dialogue is derived from Cicero's De re publica, written some three centuries later.^{[21][citation needed]} Cicero's dialogue imitates Plato's style and treats many of the same topics, and Cicero's main character Scipio Aemilianus expresses his esteem for Plato and Socrates.

Augustine of Hippo wrote his The City of God; Augustine equally described a model of the "ideal city", in his case the eternal Jerusalem, using a visionary language not unlike that of the preceding philosophers.

Islamic philosophers were much more interested in Aristotle than Plato, but not having access to Aristotle's Politics, Ibn Rushd (Averroes) produced instead a commentary on Plato's Republic. He advances an authoritarian ideal, following Plato's paternalistic model. Absolute monarchy, led by a philosopher-king, creates a justly ordered society. This requires extensive use of coercion,^[22] although persuasion is preferred and is possible if the young are properly raised.^[23] Rhetoric, not logic, is the appropriate road to truth for the common man. Demonstrative knowledge via philosophy and logic requires special study. Rhetoric aids religion in reaching the masses.^[24]

Following Plato, Ibn Rushd accepts the principle of women's equality. They should be educated and allowed to serve in the military; the best among them might be tomorrow's philosophers or rulers.^[25][26] He also accepts Plato's illiberal measures such as the censorship of literature. He uses examples from Arab history to illustrate just and degenerate political orders.^[27]

The medieval jurist Gratian in his Decretum (ca 1140) quotes Plato as agreeing with him that "by natural law all things are common to all people."^[28] He identifies Plato's ideal society with the early Church as described in the Acts of the Apostles. "Plato lays out the order", Gratian comments, "for a very just republic in which no one considers anything his own."^[29]

Thomas More, when writing his Utopia, invented the technique of using the portrayal of a "utopia" as the carrier of his thoughts about the ideal society. More's island Utopia is also similar to Plato's Republic in some aspects, among them common property and the lack of privacy.^{[30][31][32][33]}

Hegel respected Plato's theories of state and ethics much more than those of the early modern philosophers such as Locke, Hobbes and Rousseau, whose theories proceeded from a fictional "state of nature" defined by humanity's "natural" needs, desires and freedom. For Hegel this was a contradiction: since nature and the individual are contradictory, the freedoms which define individuality as such are latecomers on the stage of history. Therefore, these philosophers unwittingly projected man as an individual in modern society onto a primordial state of nature. Plato however had managed to grasp the ideas specific to his time:

Plato is not the man to dabble in abstract theories and principles; his truth-loving mind has recognized and represented the truth of the world in which he lived, the truth of the one spirit that lived in him as in Greece itself. No man can overleap his time, the spirit of his time is his spirit also; but the point at issue is, to recognize that spirit by its content.^[34]

For Hegel, Plato's Republic is not an abstract theory or ideal which is too good for the real nature of man, but rather is not ideal enough, not good enough for the ideals already inherent or nascent in the reality of his time; a time when Greece was entering decline. One such nascent idea was about to crush the Greek way of life: modern freedoms—or Christian freedoms in Hegel's view—such as the individual's choice of his social class, or of what property to pursue, or which career to follow. Such individual freedoms were excluded from Plato's Republic:

Plato recognized and caught up the true spirit of his times, and brought it forward in a more definite way, in that he desired to make this new principle an impossibility in his Republic.^[35]

Greece being at a crossroads, Plato's new "constitution" in the Republic was an attempt to preserve Greece: it was a reactionary reply to the new freedoms of private property etc., that were eventually given legal form through Rome. Accordingly, in ethical life, it was an attempt to introduce a religion that elevated each individual not as an owner of property, but as the possessor of an immortal soul.

Mussolini admired Plato's Republic, which he often read for inspiration.^[36] The Republic expounded a number of ideas that fascism promoted, such as rule by an elite promoting the state as the ultimate end, opposition to democracy, protecting the class system and promoting class collaboration, rejection of egalitarianism, promoting the militarization of a nation by creating a class of warriors, demanding that citizens perform civic duties in the interest of the state, and utilizing state intervention in education to promote the development of warriors and future rulers of the state.^[37] Plato was an idealist, focused on achieving justice and morality, while Mussolini and fascism were realist, focused on achieving political goals.^[38]

Martin Luther King Jr. nominated the Republic as the one book he would wish to have desert island, aside from Bible.^[39]

In 2001, a survey of over 1,000 academics and students voted the Republic the greatest philosophical text ever written. Julian Baggini argued that although the work "was wrong on almost every point, the questions it raises and the methods it uses are essential to the western tradition of philosophy. Without it we might not have philosophy as we know it."^[40] In 2021, a survey showed that the Republic is the most studied book in the top universities in the United States.^[41][42]

Plato's Republic has been influential in literature and art.

• Aldous Huxley's Brave New World has a dystopian government that bears a resemblance to the form of government described in the Republic, featuring the separation of people by professional class, assignment of profession and purpose by the state, and the absence of traditional family units, replaced by state-organized breeding.^[43]
• The Orwellian dystopia depicted in the novel 1984 had many characteristics in common with Plato's description of the allegory of the Cave as Winston Smith strives to liberate himself from it.^[44]
• In the early 1970s the Dutch composer Louis Andriessen composed a vocal work called De Staat, based on the text of Plato's Republic.^[45]
• In Robert A. Heinlein's Starship Troopers, his citizen can be compared to a Platonic Guardian, without the communal breeding and property, but still having a militaristic base. Although there are significant differences in the specifics of the system, Heinlein and Plato both describe systems of limited franchise, with a political class that has supposedly earned their power and wisely governs the whole. The Republic is specifically attacked in Starship Troopers. The arachnids can be seen as much closer to a Republic society than the humans.^[46]
• The film The Matrix models Plato's Allegory of the Cave.^[47]
• In fiction, Jo Walton's 2015 novel The Just City explored the consequences of establishing a city-state based on the Republic in practice.

In his 1934 Plato und die Dichter (Plato and the Poets), as well as several other works, Hans-Georg Gadamer describes the utopic city of the Republic as a heuristic utopia that should not be pursued or even be used as an orientation-point for political development. Rather, its purpose is said to be to show how things would have to be connected, and how one thing would lead to another—often with highly problematic results—if one would opt for certain principles and carry them through rigorously. This interpretation argues that large passages in Plato's writing are ironic, a line of thought initially pursued by Kierkegaard.

The city portrayed in the Republic struck some critics as harsh, rigid, and unfree; indeed, as totalitarian. Karl Popper gave a voice to that view in his 1945 book The Open Society and Its Enemies, where he singled out Plato's state as a dystopia. Popper distinguished Plato's ideas from those of Socrates, claiming that the former in his later years expressed none of the humanitarian and democratic tendencies of his teacher.^[48][49][50] Popper thought Plato's envisioned state totalitarian as it advocated a government composed only of a distinct hereditary ruling class, with the working class—who Popper argues Plato regards as "human cattle"—given no role in decision making. He argues that Plato has no interest in what are commonly regarded as the problems of justice—the resolution of disputes between individuals—because Plato has redefined justice as "keeping one's place".^[51]

Popper insists that the Republic "was meant by its author not so much as a theoretical treatise, but as a topical political manifesto",^[52] and Bertrand Russell argues that at least in intent, and all in all not so far from what was possible in ancient Greek city-states, the form of government portrayed in the Republic was meant as a practical one by Plato.^[53]

Many critics have suggested that the dialogue's political discussion actually serves as an analogy for the individual soul, in which there are also many different "members" that can either conflict or else be integrated and orchestrated under a just and productive "government." Among other things, this analogical reading would solve the problem of certain implausible statements Plato makes concerning an ideal political republic.^[54] Norbert Blössner (2007)^[55] argues that the Republic is best understood as an analysis of the workings and moral improvement of the individual soul with remarkable thoroughness and clarity. This view, of course, does not preclude a legitimate reading of the Republic as a political treatise (the work could operate at both levels). It merely implies that it deserves more attention as a work on psychology and moral philosophy than it has sometimes received.

Eric Voegelin in Plato and Aristotle (Baton Rouge, 1957), gave meaning to the concept of 'Just City in Speech' (Books II–V). For instance, there is evidence in the dialogue that Socrates himself would not be a member of his 'ideal' state. His life was almost solely dedicated to the private pursuit of knowledge. More practically, Socrates suggests that members of the lower classes could rise to the higher ruling class, and vice versa, if they had 'gold' in their veins—a version of the concept of social mobility. The exercise of power is built on the 'noble lie' that all men are brothers, born of the earth, yet there is a clear hierarchy and class divisions. There is a tripartite explanation of human psychology that is extrapolated to the city, the relation among peoples. There is no family among the guardians, another crude version of Max Weber's concept of bureaucracy as the state non-private concern. Together with Leo Strauss, Voegelin considered Popper's interpretation to be a gross misunderstanding not only of the dialogue itself, but of the very nature and character of Plato's entire philosophic enterprise.

The paradigm of the city—the idea of the Good, the Agathon—has manifold historical embodiments, undertaken by those who have seen the Agathon, and are ordered via the vision. The centerpiece of the Republic, Part II, nos. 2–3, discusses the rule of the philosopher, and the vision of the Agathon with the Allegory of the Cave, which is clarified in the theory of forms. The centerpiece is preceded and followed by the discussion of the means that will secure a well-ordered polis (city). Part II, no. 1, concerns marriage, the community of people and goods for the guardians, and the restraints on warfare among the Hellenes. It describes a partially communistic polis. Part II, no. 4, deals with the philosophical education of the rulers who will preserve the order and character of the city-state.

In part II, the Embodiment of the Idea, is preceded by the establishment of the economic and social orders of a polis (part I), followed by an analysis (part III) of the decline the order must traverse. The three parts compose the main body of the dialogues, with their discussions of the "paradigm", its embodiment, its genesis, and its decline.

The introduction and the conclusion are the frame for the body of the Republic. The discussion of right order is occasioned by the questions: "Is justice better than injustice?" and "Will an unjust man fare better than a just man?" The introductory question is balanced by the concluding answer: "Justice is preferable to injustice". In turn, the foregoing are framed with the Prologue (Book I) and the Epilogue (Book X). The prologue is a short dialogue about the common public doxai (opinions) about justice. Based upon faith, and not reason, the Epilogue describes the new arts and the immortality of the soul.

Some of Plato's proposals have led theorists like Leo Strauss and Allan Bloom to ask readers to consider the possibility that Socrates was creating not a blueprint for a real city, but a learning exercise for the young men in the dialogue. There are many points in the construction of the "Just City in Speech" that seem contradictory, which raise the possibility Socrates is employing irony to make the men in the dialogue question for themselves the ultimate value of the proposals. In turn, Plato has immortalized this 'learning exercise' in the Republic.

One of many examples is that Socrates calls the marriages of the ruling class 'sacred'; however, they last only one night and are the result of manipulating and drugging couples into predetermined intercourse with the aim of eugenically breeding guardian-warriors. Strauss and Bloom's interpretations, however, involve more than just pointing out inconsistencies; by calling attention to these issues they ask readers to think more deeply about whether Plato is being ironic or genuine, for neither Strauss nor Bloom present an unequivocal opinion, preferring to raise philosophic doubt over interpretive fact.

Strauss's approach developed out of a belief that Plato wrote esoterically. The basic acceptance of the exoteric-esoteric distinction revolves around whether Plato really wanted to see the "Just City in Speech" of Books V–VI come to pass, or whether it is just an allegory. Strauss never regarded this as the crucial issue of the dialogue. He argued against Karl Popper's literal view, citing Cicero's opinion that the Republic's true nature was to bring to light the nature of political things.^[56] In fact, Strauss undermines the justice found in the "Just City in Speech" by implying the city is not natural, it is a man-made conceit that abstracts away from the erotic needs of the body. The city founded in the Republic "is rendered possible by the abstraction from eros".^[57]

An argument that has been used against ascribing ironic intent to Plato is that Plato's Academy produced a number of tyrants who seized political power and abandoned philosophy for ruling a city. Despite being well-versed in Greek and having direct contact with Plato himself, some of Plato's former students like Clearchus, tyrant of Heraclea; Chaeron, tyrant of Pellene; Erastus and Coriscus, tyrants of Skepsis; Hermias of Atarneus and Assos; and Calippus, tyrant of Syracuse ruled people and did not impose anything like a philosopher-kingship. However, it can be argued whether these men became "tyrants" through studying in the academy. Plato's school had an elite student body, some of whom would by birth, and family expectation, end up in the seats of power. Additionally, it is important that it is by no means obvious that these men were tyrants in the modern, totalitarian sense of the concept. Finally, since very little is actually known about what was taught at Plato's Academy, there is no small controversy over whether it was even in the business of teaching politics at all.^[58]

Several Oxyrhynchus Papyri fragments were found to contain parts of the Republic, and from other works such as Phaedo, or the dialogue Gorgias, written around 200–300 CE.^[59] Fragments of a different version of Plato's Republic were discovered in 1945, part of the Nag Hammadi library, written c. 350 CE.^[60] These findings highlight the influence of Plato during those times in Egypt.
