(philosophy)

Pragmatism is a philosophical movement that includes those who claim that an ideology or proposition is true if it works satisfactorily, that the meaning of a proposition is to be found in the practical consequences of accepting it, and that unpractical ideas are to be rejected. Pragmatism, in William James' eyes, was that the truth of an idea needed to be tested to prove its validity. Pragmatism began in the late nineteenth century with Charles Sanders Peirce and his pragmatic maxim. Through the early twentieth-century it was developed further in the works of William James, John Dewey and—in a more unorthodox manner—by George Santayana. Other important aspects of pragmatism include anti-Cartesianism, radical empiricism, instrumentalism, anti-realism, verificationism, conceptual relativity, a denial of the fact-value distinction, a high regard for science, and fallibilism.
