The ancient Greek philosopher famous for his contributions to ethics and politics is Aristotle. A student of Plato, Aristotle made profound contributions across various fields, including metaphysics, biology, ethics, politics, and logic. His ethical philosophy emphasizes virtue, the concept of the "golden mean," and the importance of rationality in achieving a good life. In politics, his work "Politics" examines different government types and advocates for a balanced approach, favoring a constitutional government. Aristotle's comprehensive approach to philosophy established him as a foundational figure in Western thought, influencing countless philosophers and political theorists throughout history.
