The Peripatetic School was an ancient Greek philosophical institution founded by the philosopher Aristotle in the 4th century BCE. It was located in the Lyceum, a public gymnasium in Athens. The school is known for its emphasis on empirical observation and the study of various subjects, including ethics, politics, and natural sciences. Students of the Peripatetic School engaged in discussions while walking around the Lyceum, which is how the term "peripatetic," meaning "to walk about," originated. The school produced notable philosophers, including Theophrastus, who succeeded Aristotle and contributed significantly to botany and ethics.
