The famous ancient Greek philosopher known for the concept of the "Golden Mean" is Aristotle. His philosophy emphasizes moderation and the idea that moral virtue is achieved through a balanced approach between extremes. In works such as Nicomachean Ethics, Aristotle explores how virtue lies between excess and deficiency, providing a framework for ethical behavior. His teachings have profoundly shaped Western thought, influencing fields like ethics, politics, and education. Aristotle's concept of the Golden Mean continues to resonate as a guiding principle for personal and moral development.
