Republic, Plato's best known and most frequently read dialogue, although receiving a flood of translations and philosophical analysis over the last 100 years, has in recent times been quite short of detailed commentaries. In particular, a full edition of the introductory sections of the dialogue, representing, probably, a single papyrus roll in the original text (the division into our 'Books' came later), has not been attempted for more than fifty years. In that period scholarship has moved on, and this edition aims to take into account recent developments in the study of Plato's literary style as well as of his ideas. The arguments have always been of great interest to philosophers, especially the sophist Thrasymachus' clash with Socrates in defending injustice as the most profitable life-choice (which of them wins the argument?). But there is a great deal more to this introduction than abstract ideas; Plato chooses to begin his great work by staging a dramatic debate, arising out of a social meeting between Socrates and friends in the Athenian port of the Piraeus during a religious festival. The case against justice as a state of affairs leading to eudaimonia ('happiness') is put with great force and humour, not to mention bad temper, and in the cut-and-thrust of argument and the clash of personalities, Plato brings vividly to life the cultural and social world of his times and the crucial issues at stake for his contemporaries. He also puts as effectively as possible the adversarial case which Socrates has to answer in the rest of Republic. This edition is aimed principally at readers without Greek; however, following the main purpose of the Series, a spectrum of needs is catered for, ranging from those studying through the original text to those working with the translation.
Plato (Greek: Πλάτων), born Aristocles (c. 427 – 348 BC), was an ancient Greek philosopher of the Classical period who is considered a foundational thinker in Western philosophy and an innovator of the written dialogue and dialectic forms. He raised problems for what became all the major areas of both theoretical philosophy and practical philosophy, and was the founder of the Platonic Academy, a philosophical school in Athens where Plato taught the doctrines that would later become known as Platonism. Plato's most famous contribution is the theory of forms (or ideas), which has been interpreted as advancing a solution to what is now known as the problem of universals. He was decisively influenced by the pre-Socratic thinkers Pythagoras, Heraclitus, and Parmenides, although much of what is known about them is derived from Plato himself. Along with his teacher Socrates, and Aristotle, his student, Plato is a central figure in the history of philosophy. Plato's entire body of work is believed to have survived intact for over 2,400 years—unlike that of nearly all of his contemporaries. Although their popularity has fluctuated, they have consistently been read and studied through the ages. Through Neoplatonism, he also greatly influenced both Christian and Islamic philosophy. In modern times, Alfred North Whitehead famously said: "the safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato."
