|Metalanguage: metalanguage is the language in which linguistic forms, the meaning of expressions and sentences, the use of language, as well as the admissibility of formations, and the truth of statements are discussed. The language you refer to is called object language. A statement about the form, correctness, or truth of another statement thus includes both, i.e. object language and meta language. See also richness, truth-predicate, expressiveness, paradoxes, mention, use, quasi-reference, quotation, hierarchy, fixed points._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Metalanguage/Object Language/Tarski/Black: the distinction has to be heeded very thoroughly. Example (c) The statement in italics is wrong - then: (1) c is identical with the statement "c is false" - on the other hand you cannot deny: (2) "c is false" is true iff c is false - from (1) and (2) follows: - (3) c is true iff c is false - this is a contradiction - Solution/Black: the contradiction arises, because the term "statement" is ambiguous - (primary/secondary) - then "the primary statement in italics is false" - (that is secondary) - with that, no primary statement itself is in italics.

T Def/Tarski/Black: Method: "true" is regarded as predicate of the object language - Important argument: the statement "S is true" then also belongs to the metalanguage.

Metalanguage/Names/Black: Important argument: the metalanguage contains no rule for converting the names from the object language! It must be seen as a kind of logical coincidence that E.g. names were always enclosed in commas. No structural relationship could be found between a word in the object language and its name in the metalanguage._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
