Pragmatism is a philosophical movement that originated in the United States during the late 19th century, spearheaded by thinkers such as Charles Sanders Peirce, William James, and John Dewey. This approach places emphasis on action, practicality, and interaction with the external world. Pragmatists believe that knowledge is not static or absolute, but rather, it evolves and adapts through human actions and interactions. They view truth as something that is sought after through scientific inquiry and experimentation and not pre-determined or universal. In pragmatism, reality is not a fixed entity but is constantly being shaped and reshaped through actions. It is a philosophy deeply rooted in research and experimentation, justifying beliefs through their practical applications and outcomes.
