Refers to the set of theories put forward by Socrates and Plato (427–347 BC) in their search for an Absolute Truth. Socrates and Plato questioned the fundamentals of reality, knowledge, and human nature. From these teachings emerged the Socratic method—the process of gaining knowledge by carefully questioning and then criticizing the answers. Socrates believed that all humanity possessed and was capable of such knowledge. Plato believed his ideas, referred to as forms, were all connected and arranged in a hierarchy, with the greatest of all forms being the Forms of Good. He believed that only the most knowledgeable would reach ultimate truth.
