Socrates was a classical Greek philosopher who is credited with laying the fundamentals (基础) of modern Western philosophy. He is a mysterious figure known chiefly through the accounts of later classical writers, especially the writings of his most famous student Plato.Socrates has become well known for his contribution to the field of ethics. His method of teaching, known as the Socratic Method, by asking and answering questions to stimulate critical thinking and to explain ideas remains a commonly used tool in a wide range of discussions. He also made important and lasting contributions to the field of epistemology (认识论) and logic, and the influence of his ideas and approach remains a strong foundation for Western philosophy that followed.Socrates was the most colorful figure in the history of ancient philosophy. His fame was widespread in his own time, and his name soon became a household word although he constructed no philosophical system, established no school, and founded no sect (宗派).
