Truth Conditional. KehlBayern October 24, 2011 Entertainment “A variant of the Correspondence Theory, and akin to Redundancy Theory. It was developed by the Polish logician Alfred Tarski (1902-1983), and applied to language by British philosopher D. Davidson. (See also Montague Grammar). Semantic theory for sentences rather than words (see also Semantics, Lexical). We know the meaning of a sentence if we know the conditions under which it would be true. The basica idea is that a sentence like ‘Snow is white’ is true in English (and ‘La neige est blanche’ is true in French) if and only if snow is white. Truth is thus relative to a language, and Tarski applies the theory primarily to certain formal languages, developed so as to deal with the ‘liar’ paradox is ‘I am now lying’ true or false?). For this and other reasons the full statement of the theory is very complicated, which is itself one of the objections to it.” M.
