<p>utrecht</p> <p><b>New page</b></p><div>'''Necessary truth''' is a sentence which is [[truth|true]] by virtue of its [[logical structure]].<br /> <br /> === Example ===<br /> <br /> sentence (i) is necessarily true due to the meaning of the [[logical constant]]s ''every, or'', independently of the words ''raven'' and ''black'': <br /> <br /> (i) Every raven is black or not black<br /> <br /> Sentence (i) is also called a [[tautology]]. All sentences that are not necessarily true are contingently true (see [[contingent truth]]). See also [[analytic truth]].<br /> <br /> === Links ===<br /> <br /> [http://www2.let.uu.nl/UiL-OTS/Lexicon/zoek.pl?lemma=Necessary+truth&amp;lemmacode=490 Utrecht Lexicon of Linguistics]<br /> <br /> === References ===<br /> <br /> * Gamut, L.T.F. 1991.
