Aristotle (384-322 BC) was a Greek philosopher and polymath who profoundly influenced Western thought. He studied under Plato at the Academy in Athens and later established his own school, the Lyceum. Aristotle made major contributions to almost every field of human knowledge of his time, including logic, metaphysics, biology, physics, ethics, politics, and aesthetics. His works cover a wide range of subjects and have had a lasting impact on philosophy, science, and literature.
