Socrates ( /ˈsɒkrətiːz/; Greek: Σωκράτης, Ancient Greek pronunciation: [sɔːkrátɛːs], Sōkrátēs; c. 469 BC – 399 BC) was a classical Greek Athenian philosopher. Credited as one of the founders of Western philosophy, he is an enigmatic figure known chiefly through the accounts of later classical writers, especially the writings of his students Plato and Xenophon, and the plays of his contemporary Aristophanes. Many would claim that Plato's dialogues are the most comprehensive accounts of Socrates to survive from antiquity.
