The Nicomachean Ethics is a foundational text in Western philosophy written by the ancient Greek philosopher Aristotle. It explores the nature of the good life and the concept of virtue, emphasizing the importance of character and moral virtue in achieving happiness. In this work, Aristotle argues that ethical behavior is a mean between extremes, advocating for a balanced approach to life. He introduces key ideas such as the importance of practical wisdom and the role of community in shaping moral character, making it a significant influence on both philosophy and ethics throughout history.
