|Theoretical terms: Theoretical terms are expressions for unobservable objects which are indirectly derived from the application of their methods by a theory, and which are in accordance with the application rules of the vocabulary of the theory.

|Theoretical terms: recognition of objects coincides with the mastering of statements.
Empirical content = categorical observation sentences: linking theory with observation - two theories are equivalent if all categorical observation sentences are identical - theory implies categorical observation sentences without being implied by them.
Theoretical terms do not even exist in categorical observation sentences.
Theory: rewording: E.g. exchanging electron and molecule - an arbitrary empirical sentence (with theoretical term), however, will be evaluated oppositely - Mark theoretical terms and assign them to the two theories: then no problem, no relativism.
Comparative/Existence/language learning/Ontology/Quine: theoretical terms come into play through comparatives -smaller than this spot-" Important argument: although it is unobservable, the existence does not need to be discarded -" different: E.g. compound terms: -blue apple-: here is a non-existence of observable objects = non-existence in general -" theoretical terms: can otherwise be introduced through relative clauses or descriptions._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
