4. Philosophers and Kings: Plato's Republic, Books I-II

Total duration is approximately one hour; it is recommended to watch in segments for better absorption. This lecture is the fourth in Yale University's introductory course on political philosophy, focusing on the core arguments of Books I and II of Plato's *Republic*, and delving into the classic proposition of "the philosopher and the king" that runs throughout the history of Western political thought. The course first situates the *Republic* within its historical context and surveys the multiple interpretive approaches it has received in the political-philosophical tradition. It then systematically analyzes Plato's argumentative logic concerning the nature of justice, and examines how the ideal of the "philosopher-king" shaped later imaginations of the ideal polity. The key highlight lies in how the professor places this ancient Greek text within a contemporary framework of political-theoretical dialogue, revealing that the *Republic* is not a simple utopian blueprint but rather a profound inquiry into the relationships among power, knowledge, and virtue. The course places strong emphasis on precise conceptual definition and close textual reading, with clearly structured argumentation. This course is suitable for beginners in philosophy or political science, as well as for viewers interested in the history of Western thought. It is recommended that viewers read the course materials or the original text of the *Republic* alongside the lectures to deepen their understanding.
