Aristotle

Aristotle was one of the most influential thinkers in human history, a philosopher, scientist, and teacher whose systematic investigations of nature, ethics, politics, logic, and literature helped establish the foundations of Western intellectual inquiry. Born in Stagira, in northern Greece, he was the son of a physician associated with the Macedonian royal court, an upbringing that may have encouraged his lifelong fascination with the natural world. At seventeen, he travelled to Athens and entered Plato's Academy, where he studied for approximately twenty years. Although deeply influenced by his teacher, Aristotle developed a distinctive philosophical method grounded in observation, classification, and the careful examination of experience. After leaving Athens, he travelled through the eastern Mediterranean and later served as tutor to the young Alexander the Great before returning to establish his own school, the Lyceum.

Aristotle's surviving works encompass an extraordinary range of human knowledge. His Nicomachean Ethics examined happiness, virtue, friendship, and the cultivation of character, while Politics explored the nature of civic life and the organisation of society. His Metaphysics, Physics, and biological writings investigated causation, change, and the principles governing the natural world, while Poetics offered one of antiquity's most influential analyses of tragedy and literary art. Unlike Plato's emphasis on transcendent Forms, Aristotle sought to understand reality through the structures and purposes discoverable within the world itself. Following Alexander's death, political hostility toward Macedonian influence prompted Aristotle to leave Athens, and he died in Chalcis in 322 BC. His philosophical legacy profoundly shaped medieval Islamic and Christian scholarship, Renaissance humanism, and the development of modern science and philosophy.
