Truth is most often used to mean being in accord with fact or reality, or fidelity to an original or to a standard or ideal. The commonly understood opposite of truth is falsehood, which, correspondingly, can also take on a logical, factual, or ethical meaning. The concept of truth is discussed and debated in several contexts, including philosophy and religion. Many human activities depend upon the concept, where its nature as a concept is assumed rather than being a subject of discussion; these include most (but not all) of the sciences, law, and everyday life. Definition and etymology An angel carrying the banner of "Truth", Roslin, Midlothian Thus, 'truth' involves both the quality of "faithfulness, fidelity, loyalty, sincerity, veracity", and that of "agreement with fact or reality", in Anglo-Saxon expressed by sōþ (Modern English sooth). All Germanic languages besides English have introduced a terminological distinction between truth "fidelity" and truth "factuality".
