Peripatetic

The Peripatetic school was founded by Aristotle at the Lyceum in Athens — named for the peripatos, the covered walkways where he lectured. In contrast to Plato's world of ideal Forms, the Peripatetics grounded philosophy in careful empirical observation of the natural world. Aristotle and his followers produced systematic works across logic, physics, biology, ethics, politics, rhetoric, and aesthetics. Transmitted through Averroes and Aquinas, the school's influence shaped medieval philosophy in both the Islamic and Christian worlds.
