Truth is a philosophical concept derived from the everyday notion of 'telling the truth' as opposed to telling a deliberate falsehood. "Correspondence" theories of truth hold that a statement is true if it corresponds to the "facts" of experience. "Coherence" theories of truth contend, however, that facts are themselves statements of a kind whose truth cannot be tested by looking for further corresponsences, but only considering their logical coherence with other statements about supposed reality. "Pragmatic" theories of truth stress that the only usefully testable "truths" are those that enable us to anticpate or control the course of events.
