Aristotle was a Greek philosopher and polymath who lived from 384 to 322 BCE. He is considered one of the most influential figures in Western philosophy, contributing to various fields such as metaphysics, ethics, politics, and natural sciences. His works laid the groundwork for much of modern thought and inquiry. A student of Plato, Aristotle developed his own ideas, emphasizing empirical observation and logic. He founded the Lyceum, where he taught and wrote extensively. His writings, including Nicomachean Ethics and Politics, continue to be studied and revered for their insights into human nature and society.
