 In Pragmatism nothing practical or useful is held to be necessarily true, nor is anything which helps to survive merely in the short term.For example, to believe my cheating spouse is faithful may help me feel better now, but it is certainly not useful from a more long-term perspective because it doesn't accord with the facts (and is therefore not true).While pragmatism started out simply as a criterion of meaning, it quickly expanded to become a full-fledged epistemology with wide-ranging implications for the entire philosophical field.
