Abstract

It can be argued that political philosophy begins with the question “What is justice?” raised by Socrates in Plato’s Republic. The debate about justice that takes place in the dialogue leads to two opposing positions: the position represented by Socrates, according to which justice is a universal and timeless moral value that provides the foundation for order in any human society, and the position represented by Thrasymachus, according to which justice is purely conventional and relative to human laws that vary according to times and customs: “nothing else than the interest of the stronger.” This debate, initiated by Plato, continues throughout the history of political thought. Already in the Republic, it inspires additional questions: Do moral values hold in politics? What is human nature? What are the origins and the end of the state? Can a war be just? What are the limits of governmental power? How much liberty should citizens enjoy? Who should rule? What is the best form of government? Answers to these questions, posed in a single work written more than twenty-four centuries ago, have served in one way or another as the basis upon which the main themes of political and international relations theory have developed. This book provides a fresh, historical introduction to Western political philosophy from its beginning in ancient Greece to modern times. It is designed for students of philosophy, politics and international relations, and other fields, individuals taking courses in the history of political thought, and for general readers who have an interest in the subject. It is written simply and candidly, but without sacrificing intellectual depth. This book demonstrates the continuing significance of centuries old political and philosophical debates and problems. Recurring themes include discussions concerning human nature, different views of justice, the origin of government and law, the rise and development of various forms of government, idealism and realism in international relations, the distinction between just and unjust war, and the nature of legitimate sover-eignty. It explores tensions between ancient and modern ideas and presents the history of political thought as a great debate about politics and ethics in which political thinkers of various eras expound on their views in turn.
