Pragmatism is an American philosophy that emerged in the 1850s. It views ideas as tools for solving problems and believes that the meaning and truth of ideas come from their practical consequences and real-world applications. Major exponents include Charles Sanders Peirce, William James, and John Dewey. Pragmatism emphasizes experience, action, and practical results over abstract theorizing. It influenced progressive education by stressing learning by doing, integrating subjects, using projects, and making education more relevant to students' lives and society.
