Theory/Object level/Field: we assume a theory here instead of the truth of the theory. Problem: the theory requires mathematical entities.

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.

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".

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.
