Pragmatism is the theory that ideas or principles are true so far as they work. In general, pragmatists rely on empirical or experimental methods and reject apriorism as a source of human knowledge. Because pragmatists differ among themselves in their use of the term, it is difficult to give a short precise definition. For adequate treatment see Dagobert A. Runes' Dictionary of Philosophy.
