The Republic is Plato's most complete and incisive work – a detailed study of the problem of how best to ensure that justice exists in a real society, rather than as merely the product of an idealized philosophical construct. The work considers several competing definitions of justice, and looks closely not only at what exactly a "just life" should be, but also at the ways in which society can organise itself in ways that maximise the opportunities for every member to live justly. Much of the discussion is via imagined dialogues, giving Plato the opportunity to deploy the tools of Socratic debate to remarkable effect; nowhere else, it can be argued, is the Socratic dialectic better exemplified than in The Republic. In large measure, Plato's success is the product of the acute analytical ability that he demonstrates throughout his surviving oeuvre. No one is better at understanding the relationships between the various parts of a successful argument than Plato, and The Republic also demonstrates the Greek philosopher has few peers when it comes to looking for and highlighting the core assumptions that underlie an argument. The demolition of competing views that Plato puts into the mouth of Socrates is based on a series of relentless interventions and counter-examples that this mastery makes possible. Combining analytical skills with great powers of reasoning to produce a well-structured solution that deals emphatically with counter-arguments, Plato crafts one of the most enduring works of philosophy in the entire western canon.

The Republic is a Socratic dialogue, written by Plato around 380 BCE, concerning the definition of justice, the order and character of the just city-state and the just man. The dramatic date of the dialogue has been much debated and though it must take place some time during the Peloponnesian War, "there would be jarring anachronisms if any of the candidate specific dates between 432 and 404 were assigned". It is Plato's best-known work and has proven to be one of the most intellectually and historically influential works of philosophy and political theory. In it, Socrates along with various Athenians and foreigners discuss the meaning of justice and examine whether or not the just man is happier than the unjust man by considering a series of different cities coming into existence "in speech", culminating in a city (Kallipolis) ruled by philosopher-kings; and by examining the nature of existing regimes. The participants also discuss the theory of forms, the immortality of the soul, and the roles of the philosopher and of poetry in society.

Nicholas D. Smith presents an original interpretation of the Republic, considering it to be a book about knowledge and education. Over the course of Summoning Knowledge in Plato's Republic, he argues for four main theses. Firstly, the Republic is not just a work that has a lot to say about education; it is a book that depicts Socrates as attempting to engage his interlocutors in such a way as to help to educate them and also engages us, the readers, in a way that helps to educate us. Secondly, Plato does not suppose that education, properly understood, should have as its primary aim putting knowledge into souls that do not already have it. Instead, the education Plato discusses, represents occurring between Socrates and his interlocutors, and hopes to achieve in his readers is one that aims to arouse the power of knowledge in us and then to begin to train that power always to engage with what is more real, rather than what is less real. Thirdly, Plato's conception of knowledge is not the one typically presented in contemporary epistemology. It is, rather, the power of conceptualization by the use of exemplars. And finally, Plato engages this power of knowledge in the Republic in a way he represents as only a kind of second-best way to engage knowledge - and not as the best way, which would be dialectic. Instead, Plato uses images that summon the power of knowledge to begin the process by which the power may become fully realized.

In its examination of two of Plato's key works, Soul, World, and Idea: An Interpretation of Plato's Republic and Phaedo reveals the key role that images and our capacity for image-making play in the relationship among soul, world, and Idea. This bookbegins and ends with a reading of the Republic. Daniel Sherman turns midway to the Phaedo to further analyze the nature of the soul and its relation to the nature of the Ideas, then returns to apply the conclusions to the rest of the Republic. Sherman's focus is on the ontological and epistemological argument, including attention to the dramatic detail. He argues that the ontology of the Ideas in the Republic and the Phaedo is inseparable from the ontology of human being, that is, from the structure and life of the soul. On this interpretation, the Ideas are seen as indeed objective but as in a sense also a product of a permanent dialectical relationship. The Ideas, though something more than concepts, do not have any real independent existence outside of this human dialectical triad of world, soul and Idea. The stability of the Ideas need not be grounded in a static otherworldliness, and the condition of meaning is not temporally prior to human existence in general. The result is a new interpretation concerning the realm of the Ideas, the immortality of the soul, and the lived in world of their interaction in the production of interpretive images. Sherman argues that the platonic soul is immortaland the Ideas eternal wholly and solely in human (dialogical) activity--the rest is muthologia--and that the world of our experience is a product of an ongoing act of interpretation or dianoetic dialegesthai. This reinterpretation of the platonic Ideas will be especially interesting to students and scholars of classics, ancient philosophy, and continental philosophy.
