Correcht/True/Truth/Correctness/Reference/Tugendhat: a speech event is only called a right (correct), when another one is called right - then it has the sense of "true" - that constitutes the reference to objects. - (>Dummett?)
Correctness/Language/Tugendhat: E.g. signal language of animals or humans, rules causal or conventional, then the use is considered "right" - then classification expressions = quasi-predicates (only in presence of the object).
Regardless of situation: when the perceptual situation is specified by spatio-temporal localization and is thus objectified.
If the observer speaks a situation-independent language, he can respond to a situation-dependent language (e.g. of measuring instruments) with the attribution of truth/falsehood.
Truth: if the speaker only has quasi-predicates, he would have to be able to distinguish between regulatory compliance and situation conformity - then correcting errors about verification rules - I 446 but by definition not if only quasi-predicate available - Solution: singular term, then constancy of an identifiable - I 519 "right"/Tugendhat: Basic Concept
Truth/Correctness/Tugendhat: the false use of a term (lie) presupposes that it is used in a rule-compliant way (!) - therefore it is necessary to separate correctness and truth - it must be possible to refer to other situations with singular terms and quantifiers
