The Megarian school was an ancient philosophical movement founded in the 4th century BCE by Euclid of Megara. It emerged from the teachings of Socrates and focused on logic, ethics, and the nature of reality. The school is known for its emphasis on dialectical reasoning and the use of paradoxes to explore philosophical questions. Members of the Megarian school, including notable philosophers like Chrysippus and Diodorus Cronus, often debated issues related to existence and the nature of knowledge. They contributed to the development of Stoicism and influenced later philosophical thought, particularly in the areas of logic and ethics.
