| Consistency | Henkin | Quine IX 224 Henkin: shows the consistency of a ω-contradictory (omega-contradictory) system. (Also Goedel and Tarski). Just interpret "F" as true for all but those objects x that fulfill (7). (7) x ε N, x ≠ 0, x ≠ 1, x ≠ 2... ad infinitum >Sets/Henkin. A theory that is ω-contradictory seems unacceptable even if it is consistent. But according to Henkin, it is easy to see that the term and its definition are misleading. If a system is consistent and yet allows "Ex(x e N u ~Fx)" and "F0", "F1"...all as theorems, and if we guarantee the interpretation of "0" , "1" etc. as names of numbers, then the problem seems to be to interpret "N" as "number" and not more comprehensive. Henkin: shows that "N" can be interpreted as N containing extras even under the most favorable circumstances. (See Sets/Henkin) If the system is ω-contradictory, N must even be interpreted that way. ((s) "Extras": e.g. "...and their successors"). Sometimes it is then possible to limit "N" so that it avoids the extras, and sometimes this is not possible. For example, for every formifiable condition that is verifiably met by 0,1,2... ad infinitum, there is another condition that we can prove is also met by 0,1,2... and yet not by all things that meet the first condition. This is the chronic form of ω-contradictoriness that cannot be cured by an improved version of "N". (Quine: "numerically insegregative"). >Löwenheim. Def Omega-contradictory/(w)/Goedel: (Goedel 1931) is a system when there is a formula "Fx" such that any one of the statements "F0", "F1", "F2",... can be proved ad infinitum in the system, but also "Ex(x ε N and ~Fx)". >Contradictions, >Proofs, >Provability. |

| Quantification | Quine | I 283 Indefinite singular term: quantification disappears in "something is an x such that", "everything is an x ...". I 316 Paraphrases by quantification uncover false existence assumptions. >Existence/Quine VI 41 Quantification/Quine/(s) is a postulation of objects. X 94 Quantification/variable/Quine: in the open sentence after the quantifier "x" stands at a point where a name could be - E.g. also names of numbers - the sentences do not say that names or numbers are walking- "EF" does not say, "is a predicate such and such", but an object that is called by the predicate is so and so" - this object could be a property (pro Frege ) - VsRussell: but not a predicate - mixing up of representation (schema) and quantification (talking about). >Predicates/Quine X 104 Apparent Quantification/Quine: Apparent values of the new quantifiable variables " p", " q ", etc.: truth values - then sentences are exceptionally names of these apparent objects - we can quantify over apparent objects - apparent objects arise from context definition. >Objects/Quine Lauener XI 38 Quantification/Lauener/(s): truth values can only be attributed to quantified sentences. >Truth Value/Quine |

| Symbols | Bigelow | I 176 Symbol/blackening/Bigelow/Pargetter: some authors believe that symbols are mere blackenings on paper (e.g. numbers) or mere noises. >Blackening of the paper, >Numbers, >Formalism. BigelowVsFormalism: Problem: on the one hand there are too many symbols and on the other hand there are not enough. Not enough: for very large numbers there is no corresponding blackening or noise. Too many: for smaller numbers there are too many different ways of representation, more than numbers can be distinguished. Example "4", "four", "IV". >Numerals, >Names of numbers, >Representation, >Presentation. |

| Variables | Frege | II 81 Variable/mathematics/logic/Frege: variables have nothing to do with change. Arithmetic: arithmetic has nothing to do with quantities like e.g. lengths - only with numbers. II 83 f Variable/Frege: a variable is not a name of an "indeterminate" or "variable" number. "X" has no properties (only in context). "Indeterminately": indeterminately is not an adjective but an adverb to the process of the calculation. "Universality": universality is not a meaning but a suggestion. Letters are rarely names of numbers: e.g. π, i and e are not variables but constants. >Indeterminacy. Solution: e.g. "n" is used in the antecedent of a conditional sentence. II 85 Number/Frege: e.g. "a variable takes a value": here, the number must play both roles: as an object it becomes a variable, as a property it is called value. >Numbers. II 87 Variable/designation/description/Frege: "x" designates nothing! X only hints at numbers. Therefore, e.g. "x² + 3x" designates nothing. The whole function only indicates. On the other hand, "sin" (sinus) is a sign that designates. But not a law yet. Law/Frege: e.g. "y = sin x". >Denotation. |

| Frege, G. | Black Vs Frege, G. | II 124 Numbers/BlackVsPlato/BlackVsFrege: false Platonism: imagining them as "extraordinary" or "special", "eternal" objects. II 125 Grammatically, however, the names of numbers (numerals) differ in important aspects from the name of physical objects. E.g. "Two people came in": Here "two" is public. Adverb. This can be transformed into "one and one: "a man came in and then another." This is not possible in the case of "red". (> Paraphrase). BlackVsFrege: These grammatical facts show that numbers are no "special kinds of objects". Frege: the great Frege, however, made no elementary mistake by accepting it anyeay, but he was never really satisfied with it. |
