| 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.

W.V.O. Quine on Theories - Dictionary of Arguments
I 34 Theory does not have to be based on intention, it was internalized in the past. I 56 QuineVsVerification: it is pointless to equate a sentence within the theory with one outside - Inter-theoretically no meaning - no additions with "or" ((s) Cf. Goodman, Davidson, "fake theories"). >Verification, >Additional hypotheses. I 57 For the time being, we retain our beliefs in theory creation. I 74 Basics for a theory: Carnap: terms - Quine: sentences. I 393 Theory is only predication, universal quantification, truth function (for derived properties) - general term (for primary properties) - (no "because"). I 429 Theory: are isolated systems, mass point, infinitesimal size: behavior in every case more typical, the closer you get to zero, therefore it is acceptable - but not allowed in ontology - unlike geometric object: Position of mass points made no sense - therefore no individuation - no identity. (> Quine, Word and Object, 1960(1), §52.) I 431 Paraphrase (no synonymy): Newton could be reformulated relativistically - like Church: "true in a higher sense" - sometimes acceptable. I 432 Theory: Structure of meaning, not choice of objects (Ramsey, Russell) Quine: new: even with physical objects they are also theoretical. Reason: sentences are semantically primary. >Frege principle. 1. Quine, W. V. (1960). Word and Object. MIT Press --- II 45 Equivalence of theories: is discovered when one discovers the possibility of reinterpretation - both true - but possibly logically incompatible. --- VI 134 Theory/Empirically equivalent/logically equivalent/Quine: Two theories can be logically incompatible and yet empirically equivalent. E.g. Riemann/Euclidean geometry. Case 1: even untransformable theories (in the same terminology, where each implies certain sentences that the other one does not imply) are empirically equivalent - no problem. Case 2: additional theoretical terms Case 3: logically incompatible. Davidson: can be traced back to case 2 - because contentious sentences depend on theoretical terms which are not empirical - therefore they are still empirically equivalent. Solution: theoretical term in question in two spellings (according to theory) - that makes them logically compatible. >Theoretical terms. VI 136 Empirically equivalent/logically incompatible/Theory/Quine: Case 2: (theory for global worlds without context embedding): solution: eliminate exotic terms (without predictive power) Important argument: then it is about consistency (otherwise QuineVsConsistency theory). Elimination: justified by the fact that we have no other access to the truth except our own theory. >Elimination. VI 139 Empirically equivalent/logically incompatible/Theory/Quine: Variant/Davidson: Both theories are valid, truth predicate: in comprehensive, neutral language. QuineVsDavidson: how much further should the variables reach then? - We need a stop, because we do not want a third theory - "everything different"/Important argument: the two systems definitely describe the same world - purely verbal question. --- XII 70 Theory form/Quine: after abstraction of the meanings of the non-logical vocabulary and the value range of the variables - reinterpretation of the theory form provides models. >Vocabulary, >Reinterpretation, >Abstraction, >Models._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
