The philosophical tradition that emerged in Greece between roughly 600 BCE and 300 CE and continued into the Roman world, asking the foundational questions about reality, knowledge, virtue, and the good life that all subsequent Western philosophy has worked from. Plato and Aristotle are its central figures, alongside Socrates, the Stoics, the Epicureans, and the major Hellenistic schools. Almost every later Western philosophical tradition can be understood as an extension, modification, or reaction against ancient philosophy.
