Redundancy theory: comprises the thesis that nothing is added to a true sentence when it is said that it is true. In other words, each sentence asserts its own truth; the appending of the truth predicate "is true" would thus be redundant. See also judgment, truth theory, truth definition, deflationism, minimalism, disquotationalism, all that he said is true, predication._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

W.V.O. Quine on Redundancy Theory - Dictionary of Arguments
VII (i) 164 Redundancy Theory/Quine: it is doubtful whether the connection of "Fa" with "Fa is true" is analytic. - - - XIII 214 Redundancy Theory/QuineVsRedundancy Theory/truth/Quine: the truth has been said to disappear, because the truth of the sentence is simply the sentence. ("Disapearance theory of truth") This is wrong: the quotation marks must not be taken lightly. We can only say that the adjective "true" is dispensable if it is applied to sentences that explicitly lie before us. Truth-predicate/true/generalization/Quine: is necessary to say that all sentences of a certain form are wrong. Or For example, a sentence that is not literal (not literally passed down) is true or false. Or E.g. that the slander paragraphs cannot be applied to true sentences or E.g. that you will tell the truth, the whole truth and nothing but the truth. N.B.: if you translate such sentences into the predicate logic, the subject of the truth- predicate is not a quotation, but a variable. These are the cases where the truth-predicate is not superfluous. Disquotation/truth/definition/Quine: the disquotational approach may still be useful when it comes to defining truth. Truth-Definition/truth/Quine: it identifies all discernible truths that the truth of the sentence is communicated by the sentence itself. But that is not a strict definition; it does not show us who could eliminate the adjective "true" XIII 215 from all contexts in which it can occur grammatically. It only shows us where we can eliminate it in contexts with quotations. Paradox/Quine: we have seen above (see liar paradox) that definability can contain a self-contradiction. It is remarkable how easily definable we found truth in the present context. How easy it can be and at the same time possibly fatal. Solution/Tarski: Separation object language/meta language. Recursion/Tarski/Quine: shows how the truth-term is first applied to atomic sentences and then to compositions of any complexity. Problem: Tarski could not yet define truth because of the variables. Sentences with variables can be true in some cases and false in others. (Open Sentences). Only closed sentences (where all variables are bound by quantifiers) can be true or false. Fulfillment/Recursion/Tarski/Quine: what Tarski recursively defines is fulfillment of a sentence by an object; is not truth. These objects are then the possible values of the free variables. After that, truth trivially results as a waste product. Def Truth/Fulfillment/Tarski: a closed sentence is true if it is fulfilled by the sequence of length 0, so to speak. Liar Paradox/Tarski/Quine: Tarski's construction is masterly and coherent, but why doesn't it ultimately solve the paradox? This is shown by the translation into symbolic logic when the sentence is formulated in object language (see paradoxes above, last section). Paradox/logical form/liar/Quine: the word "true" has the context "x is true" in the explicit reconstruction where "x" is the subject of quantifiers. Problem: the recursive definition of truth and fulfillment does not show how to "fulfill x". XIII 216 or "x is true" is eliminated. Solution: this only works if "x is true" or "fulfilled" is predicated by an explicitly given open or closed sentence._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
