Pragmatism is a philosophical tradition that began in the United States around 1870.[1] Pragmatism is a rejection of the idea that the function of thought is to describe, represent, or mirror reality[citation needed]. Instead, pragmatists consider thought to be a product of the interaction between organism and environment. Thus, the function of thought is as an instrument or tool for prediction, action, and problem solving. Pragmatists contend that most philosophical topics—such as the nature of knowledge, language, concepts, meaning, belief, and science—are all best viewed in terms of their practical uses and successes.

A few of the various but interrelated positions often characteristic of philosophers working from a pragmatist approach include:
Epistemology (justification): a coherentist theory of justification that rejects the claim that all knowledge and justified belief rest ultimately on a foundation of noninferential knowledge or justified belief. Coherentists hold that justification is solely a function of some relationship between beliefs, none of which are privileged beliefs in the way maintained by foundationalist theories of justification.
Epistemology (truth): a deflationary or pragmatist theory of truth; the former is the epistemological claim that assertions that predicate truth of a statement do not attribute a property called truth to such a statement while the latter is the epistemological claim that assertions that predicate truth of a statement attribute the property of useful-to-believe to such a statement.
Metaphysics: a pluralist view that there is more than one sound way to conceptualize the world and its content.
Philosophy of science: an instrumentalist and scientific anti-realist view that a scientific concept or theory should be evaluated by how effectively it explains and predicts phenomena, as opposed to how accurately it describes objective reality.
Philosophy of language: an anti-representationalist view that rejects analyzing the semantic meaning of propositions, mental states, and statements in terms of a correspondence or representational relationship and instead analyzes semantic meaning in terms of notions like dispositions to action, inferential relationships, and/or functional roles (e.g. behaviorism and inferentialism). Not to be confused with pragmatics, a sub-field of linguistics with no relation to philosophical pragmatism.
Additionally, forms of empiricism, fallibilism, verificationism, and a Quineian naturalist metaphilosophy are all commonly elements of pragmatist philosophies. Many pragmatists are epistemological relativists and see this to be an important facet of their pragmatism (e.g. Richard Rorty), but this is controversial and other pragmatists argue such relativism to be seriously misguided (e.g. Hilary Putnam, Susan Haack).

Charles Sanders Peirce (and his pragmatic maxim) deserves much of the credit for pragmatism,[2] along with later twentieth century contributors, William James and John Dewey.[3] Pragmatism enjoyed renewed attention after W. V. O. Quine and Wilfrid Sellars used a revised pragmatism to criticize logical positivism in the 1960s. Inspired by the work of Quine and Sellars, a brand of pragmatism known sometimes as neopragmatism gained influence through Richard Rorty, the most influential of the late twentieth century pragmatists along with Hilary Putnam and Robert Brandom. Contemporary pragmatism may be broadly divided into a strict analytic
