Peripatetic philosophers were a group of thinkers associated with the school founded by Aristotle in ancient Greece. The term "peripatetic" comes from the Greek word for "walking around," as Aristotle often taught while walking in the Lyceum of Athens. This school focused on various subjects, including ethics, politics, metaphysics, and natural sciences. The Peripatetic school emphasized empirical observation and logical reasoning. Key figures included Theophrastus, who succeeded Aristotle, and Strato of Lampsacus. Their teachings influenced later philosophical traditions, including Stoicism and Neoplatonism, and contributed significantly to the development of Western philosophy.
