The ancient Greek philosopher known for the Socratic method is Socrates himself. Socrates, who lived from approximately 470 to 399 B.C., developed this method as a form of cooperative argumentative dialogue aimed at stimulating critical thinking and illuminating ideas. The Socratic method often involves asking a series of questions that challenge assumptions and lead to deeper insights about topics. Socrates' approach emphasized the importance of questioning and discussion over dogmatic assertions, significantly impacting Western philosophy. His teachings were preserved mainly through the dialogues of his student Plato, where the Socratic method has continued to be an essential pedagogical tool.
