## Philosophy Lexicon of Arguments | |||

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. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments. | |||

I 249ff Theory/Object level/Field: we assume a theory here instead of the truth of the theory. Problem: the theory requires mathematical entities. --- I 262 Physics/Theory/Language/Ontology/Field: Thesis: in the typical physical language, sentences are essential for the description of observations that contain mathematical entities. Then a theory without mathematical entities does not allow any inference about distances and masses. - Solution: new (comparative) predicates: For example, the distance between x and y is r-times the distance between z and w, etc. - For example, the velocity of y relative to y multiplied by the time difference between z and w is r-times spatial distance between u and v (Definition acceleration without numbers). - r: is a rational number. - This distinguishes the predicates in the family - NominalismVs: these are too many predicates. --- II 46 Theory/Truth/Field: it is the assertion that the axioms of the theory are true of their objects at certain points of time (or at all times) - not the theory itself. - Variables: We leave it out here very often, but they must be understood as implicitly existing. - Instead of "pain has that and that causal role" we must say: "For every t and every c (organism) of type S to t, pain has that and that causal role in c to t". --- II 187 Ideal Theory/Quine/Field: (Quine 1960, 23-4): Suppose there is an ideal theory (in the future) that could be considered as completely true: - Problem: this ideal theory could not correct the truth values of our actual (present) individual sentences. - reason: there is no general sense in which one can equate a single sentence of a theory with a single sentence of another theory. - Quine/(s): there is no inter-theoretical translatability. - Thus there is no Truth-predicate for single sentences of a theory - Falsehood is distributed to the whole theory. - There is no fact that distributes falsehood to single sentences. - FieldVsQuine: therefore the sentences are not "intertheoretically meaningless". - Solution/Field: "partial denotation": Newton's mass partially denoted. - FieldVsKuhn/FieldVsIncommensurability: denotational refinement: (later only partial quantity) means no incommensurability. _____________ Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
