Multi-valued Logic | Dummett | II 108 Trivalent Logic: if B is false but A neither true nor false: then "If A is true then B is true" comes true, although "If A, then B" is not true! Reason: it is only because we assume, as it cannot be denied, that the sentence "A is true" is false if A is neither true nor false. New predicate for trivial axioms: "A is true": shall have the same truth value as A (not always true). II 121 Neither true nor false/Dummett: this is useful only for parts of sentences (clauses)! -> multi-value logic - independently used sentences (not complex): for these only distinction between designated and not designated truth value important. >Truth values/Dummett. III (a) 27f Third truth value/indeterminate truth value/multi-valued logic/Dummett: The "wit" (purpose) is to be able to explain "not" truth-functionally. Truth table with w, f, X. - Difference: without truth value with conditional with a false antecedent: "X" (>designated truth value) - for e.g. unicorn: "Y" (not designated truth value). |

Sense | Dummett | II (b) 72ff Sense/Dummett: The sense is a property of a single sentence, not of the full use of language. I 122 Sense/Capture/DummettVsFrege: The thought is not presented directly to the consciousness - rather grasping the sense: set of skills. I 123 The fact that the glasses are in the other jacket cannot be content of consciousness. I 124 Such examples (glasses) lead to an opposite direction according to which language is explained by thoughts that are considered to be language-independent, and not vice versa (> DummettVsEvans). - Saussure s conception of language as a code will avoid such a declaration - VsFrege: sense of the word is not the same as a part of the thought. EvansVsCompositionality. III (a) 25 Sense/Dummett: from division of states of affairs: 1) where the statement could be misused. 2) where it could be not misused. ad 1) Statement: false - conditional: false - atomic sentence or without truth value. ad 2): statement: true, Conditional: true or without truth value, atomic sentence: true. III (a) 28 Sense/Dummett: entirely determined by one knowing when it has an designated truth value and when a non-designated - finer distinctions only needed in complex sentences with operators. >Truth value/Dummett. III (b) 74 Sense/Dummett: not only through verification method, but understanding what circumstances must be realized. >Circumstances. |

Truth | Dummett | II 83 Truth/Dummett: truth comes from the act of asserting. - Closely related: correctness: saying something true means to say something correct. II 87ff Truth/Dummett: truth is an objective property of what a speaker says - and this is independent of the knowledge of the speaker or his utterance reasons - Truth is explainable by the more primitive notion of correctness. - (Correctness of sentences about the future, question, command). II 115 Truth/Dummett: truth is still necessary for deductive inferences - def valid/Dummett: an inference that contains truth. I 26ff Correspondence Theory/coherence Theory: meaning comes before truth. Davidson: Truth comes before meaning (truth conditions are defined later by the theory). - Dummett both together! Use/truth/Wittgenstein/Dummett: use theory makes concept of truth superfluous > meaning before truth. III (a) 8/9 Truth/Dummett: better: winning the game. - Therefore is necessary: in addition to declare that the goal is winning, not losing! - Part of the concept of truth is the stated goal to only make true statements. DummettVsFrege: The aim of the truth must be established before claiming, otherwise one could express the same thought, but deny it. III (a) 29 Truth/Dummett: in reality it is mostly about the distinction between designated /non-designated truth values. >Truth conditions/Dummett. III (a) 40 Truth/meaning/Dummett: "It is true that p if ... iff" is not sufficient - Use: Each conditional must be given a specific meaning. - We must be able to already understand "If P, then it is true that P" III (a) 45 Truth/Dummett: that by which a statement is true is that by which it can be recognized as true. Putnam II 214 Truth/Dummett: = Justification. - Dummett believes in final verification. PutnamVsDummett: merely idealized verification is possible. - The assertibility conditions for any sentence are not manageable. >Assertibility conditions/Searle, >Assertibility conditions/Soames. We get to know the meaning conditions by acquiring a practice; that is not an algorithm, they cannot be formalized - hence rationality cannot be formalized either. >Rationality/Putnam. |

Truth Values | Dummett | I 11 f Def Truth Value/Frege/Dummett: of the sentence: the reference - the (Fregean) " Bedeutung" ("meaning") of the sentence. I 20f Dummett: E.g. assuming the condition for true/Fals would be stated, but the two truth values were only marked with A and B, then it would be impossible to figure out which one, A or B, stood for t. One would have to recognize at least in a sample sentence what weight the speakers assign to the assertoric statement of this sentence. II 112 Def Non-designated Truth Value/Dummett: the way in which a sentence can be wrong. Def Designated truth value/Dummett: the way in which a sentence can be true - this is irrelevant for atomic sentences, only relevant for the way they contribute to a complex sentence - i.e. what the condition for an designated truth value for a composite sentence is. The truth value of the whole sentence does not arise simply from the truth value of the sub-sentences - or the subsentences do not only contribute their own truth value - or if we had a meaning theory for the whole language, perhaps we might not be able to explain the meanings of the logical constants by verification of the subsentences. - (These are three formulations for the same fact). >Compositionality. III (a) 20 Truth Value/Dummett: not by property of statements, but by behavior. - Compared to bet/command: requires: the antecedent lies in the power of the receiver: II (a) 21 Gap: if the child does not go out, it cannot have forgotten the jacket. - "Unconditional command": = material conditional: here there is no gap. III (a) 20 Meaning/Truth Value/Bet/Command/Dummett: There is an asymmetry: disobedience clearly leads to the right of disapproval - obedience does not lead to the right of reward (gap). Consequence: truth values are more likely to be extracted from bets (win/lose) than from command/behavior. III (a) 28 Designated Truth Value/Dummett: true or conditional with false antecedent (EFQ, >ex falso quodlibet) Non-designated truth value: wrong or the object is nonexistent. Validity/Multi-valued logic: valid in multi-value logic are the formulas that have a designated truth value for each allocation. >Multi-valued logic. |

Truth Values | Wright | II 239 Definition designated value/vagueness/Sorites/Wright: "a is F" has an designated value if "F" is a less misleading description as "non-F" - problem: to identify the last final object at one end of the spectrum, for which "a is F" has a designated value. -> Bivalence/Wright, >Designated truth value. |

Prior, A. | Kripke Vs Prior, A. | Prior I 169 Names/Prior: Thesis: Something that does not exist cannot be named, the same way as it cannot be pushed aside by a foot. And this neither by somebody who believes in the existence nor by somebody who does not believe in its existence. In circumstances in which object x is not present, x cannot be used as proper name in sentences and there are no facts with x. Names/KripkeVsPrior: Developed systems in which simple sentences with x are false if x does not exist and the designated truth values I 170 Follow specific rules, e.g. negations of these simple sentences become true. Order/Prior: This leads to an absolute differentiation between simple and complex sentences. Names/Kripke: Are logically without structure as well. But, because it is different in Lesniewski than in Kenny, an unbeliever is able to use names for the objects whose existence he is doubting. There are naturally names for the imagined or the simply possible world. E.g. it is possible that children develop fantasies based on what they imagine and an adult annoys them by bringing up other fantasies. The question is whether the same object is named. This is the problem for purely future or merely possible individuals as well. |
