Completeness Quine X 80
Completeness Theorem/deductive/Quantifier Logic/Quine:
(B) A scheme fulfilled by each model is provable.

Theorem (B) can be proven for many proof methods. If we imagine such a method, then (II) follows from (B).

(II) If a scheme is fulfilled by every model, then e is true for all insertions of propositions.
X 83
Proof Procedure/Evidence Method/Quine: some complete ones do not necessarily refer to schemata, but can also be applied directly to the sentences,
X 84
that emerge from the scheme by insertion. Such methods produce true sentences directly from other true sentences. Then we can leave aside schemata and validity and define logical truth as the proposition produced by these proof procedures.
1. VsQuine: this usually triggers a protest: the property "to be provable by a certain method of proof" is uninteresting in itself. It is only interesting because of the completeness theorem, which allows to equate provability with logical truth.
2. VsQuine: if one defines logical truth indirectly by reference to a suitable method of proof, one deprives the completeness theorem of its basis. It becomes empty.
QuineVsVs: the danger does not exist at all: the principle of completeness in the formulation (B) does not depend on how we define logical truth, because it is not mentioned at all! Part of its meaning, however, is that it shows that we can define logical truth by merely describing the method of proof, without losing anything of what makes logical truth interesting in the first place.
X 100
Fake theory/quantities/classes/relation/Quine: is masked pure logic. Mathematics: begins when we accept the element relationship "ε" as a real predicate and accept classes as values ​​of the quantified variables. Then we leave the realm of complete proof procedure. Logic: quantifier logic is complete. Mathematics: is incomplete.
X 119
Intuitionism/Quine: gained buoyancy through Goedel's incompleteness evidence.
XIII 157
Predicate Logic/completeness/Goedel/Quine: Goedel proved its completeness in 1930.

Definiteness Ayer I 288
Determinateness / Ayer: defined by containment: that my shoes are blacc entails that they are not brown, but not vice versa - that I write entails that anybody writes, but not vice versa - Def Determinateness / Ayer: a statement is absolutely specific in L, if no statement can be made that contains this statement, without being included in it - (> mininal / Chisholm) - then hierarchy constructible in L - problem: you may make a statement beconme more specific, by connecting another with it (conjunction,> Goodman: "fake theory" (> slingshot argument) - I 289 > Big fact: expressed by a conjunction of all independent true statements.

Slingshot Argument Ayer I 288
Assertiveness /Determination/ Ayer:defined by being contained: that my shoes are black, entails that they are not brown, but not vice versa - that I write entails that someone writes, but not vice versa. - ((s) something specific entails something vague.) - Def Assertiveness / Ayer: a statement is absolutely specific in S if no statement can be made that contains this statement, without being contained in it. - ((s) > Def minimal / Chisholm) - then there is a constructible hierarchy in S. - Problem: you can make a statement of specific when connecting another statement with it. (Conjunction, > Goodman: fake theory (> slingshot argument) - I 289 > "Big fact": expressed by a conjunction of all independent true statements .

Theories Quine 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" (Cf. Goodman, Davidson, "fake theories"). ---
I 57
For the time being, we retain our beliefs in theory creation. ---
I 74
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 not individuateable - no identity. (> Quine, Word and Object, 1960, §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. ---
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. ---
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. ---
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.

Ayer, A. J. Hempel. Vs Ayer, A. J. II 112
Demand for Partial Confirmability/(2.3)/Ayer: his criterion is supposed to determine by content that a statement S has an empirical sense if observation statements can be derived from S together with suitable auxiliary hypotheses, which cannot be derived from the auxiliary hypotheses alone. HempelVsAyer: Although this is more similar to the logical structure of the verification, it is much too permeable. ((s) >Quine-Duhem Thesis/QDT: allows just any auxiliary hypothesis).
Hempel: E.g. "If the absolute is perfect, then this (!) apple is red". This allows the derivation of the observation statements, which obviously does not follow from the auxiliary hypothesis.
((s) But it does not allow to call a green apple red).
Stace: "principle of observable species": "The facts that are denied or affirmed, must be of a type or class so that it is logically possible to observe some facts immediately, which are cases of that class or species. If a statement asserts or denies facts about a class, so that it is not logically possible to observe them directly, then the statement is not significant.
II 113
HempelVsStace: this is undecided, he does not say how we determine those classes. And that is precisely what the criterion was supposed to do. Moreover, we can always form a class that contains the fact f together with the fact which is expressed by an observation statement at our discretion, which makes f a member of a basically observable class!. Therefore, the first part of the principle, like Ayers original wording, already includes everything.
Criterion of Meaning/Ayer: Additionally: a statement has a meaning if it can be derived from observation statements together with an auxiliary hypothesis. HempelVsAyer: too permeable ((s) >"fake theories".)
Modification of 2.3/Ayer: limits the auxiliary hypothesis to statements that are either analytical or can be verified independently.
Conjunction/HempelVsAyer: this new criterion fulfills the demand for full falsifiability of an arbitrary conjunction S u N and thus has unintended empirical significance for this one.
ChurchVsAyer: Suppose there are any three observation statements, none of which implies any of the others alone, then follows for an entirely arbitrary statement S that either itself or its negation has an empirical sense according to Ayers new criterion.
