|Truth Predicate: the truth predicate of a language is the "is true" expressed in this language. Its allowance can be empirically justified or attributed to the statement on the basis of the logical form. According to the redundancy theory, the truth-predicate is fundamentally superfluous. According to W.V.O. Quine (Quine, Philosophie der Logik, 2005, p. 33), the truth predicate is merely used for generalization. For example, all sentences of a particular form are true. A language containing its own truth-predicate is semantically closed. In such a language, semantic paradoxes are possible. See also expressiveness, circularity, semantic closeness, truth, truth definition, redundancy theory, self-reference, paradoxes._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Zero digit relation: E.g. Tarski: "true" is the zero digit case of satisfaction: that means, a formula is true if it has no free variables and the zero sequence is met. - zero sequence: converges to 0. Example 1, 1/4, 1/9, 1/16, ...
Truth/logic/Putnam: the meaning of "true" and the connectives are not determined by their formal logic. -> Holism -> Quine: the distinction between the whole theory and meanings of each statement is useless.
"True"/Tarski/Putnam: all writers: the meaning of "true" is detected by any definition that meets the criterion W - the meaning can still be explained by non-semantic vocabulary (descriptive words of the object language and logical vocabulary)._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
