|Theories: theories are statement systems for the explanation of observations, e.g. of behavior or physical, chemical or biological processes. When setting up theories, a subject domain, a vocabulary of the terms to be used and admissible methods of observation are defined. In addition to explanations, the goal of the theory formation is the predictability and comparability of observations. See also systems, models, experiments, observation, observation language, theoretical terms, theoretical entities, predictions, analogies, comparisons, evidence, verification, reduction, definitions, definability._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Physical theory/Cresswell: their formalization does not need an explicit reference to the language. - (+) - possible worlds as models, not linguistic elements, only parts that can be gained from the area of the intended interpretation. - Therefore, possible worlds are no strict linguistic entities. - Then intensional model ...
If h is a topicality model of L, then for every deductive consequence α of E(L), wh ∈ V v (α) for every v ∈ N.
Theory/Cresswell: Problems arise from facts, they should not be caused by a theory.
Theory/possible worlds/Physics/Cresswell: one cannot simply limit the amount of possible worlds by his own favored physical theory which (the theory) one wants to admit. If one does that, one could not test one's own theory. - A physical theory must be rich enough to contain resources to define what the case would be if this theory was false._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
