Pragmatism originated in the United States in the late 1800s through the works of Charles Sanders Peirce, William James, and John Dewey. It is a philosophical movement that emphasizes practical consequences and actions over thought. Pragmatists believe that ideas and beliefs are true if they are useful and work in practice. The meaning and truth of ideas lies in how they can be applied and their observable, practical outcomes. Pragmatism rejects the notion of absolute truth and emphasizes change, pluralism, and adaptation through experimentation.
