Philosophical concept
According to the redundancy theory of truth (also known as the disquotational theory of truth), asserting that a statement is true is completely equivalent to asserting the statement itself. For example, asserting the sentence Snow is white' is true" is equivalent to asserting the sentence "Snow is white". The philosophical redundancy theory of truth is a deflationary theory of truth.

Redundancy theorists infer from this premise that truth is a redundant concept—in other words, that "truth" is merely a word that it is conventional to use in certain contexts but not one that points to anything in reality. The theory is commonly attributed to Frank P. Ramsey, who argued that the use of words like fact and truth was nothing but a roundabout way of asserting a proposition, and that treating these words as separate problems in isolation from judgment was merely a "linguistic muddle", though there remains some debate as to the correct interpretation of his position (Le Morvan 2004). Redundancy theorists begin by inquiring into the function of the predicate " is true" in sentences like Snow is white' is true". They reason that asserting the longer sentence is equivalent to asserting the shorter sentence "Snow is white". From this they infer that nothing is added to the assertion of the sentence "Snow is white" by quoting it, appending the predicate " is true", and then asserting the result. Most predicates attribute properties to their subjects, but the redundancy theory denies that the predicate is true does so. Instead, it treats the predicate is true as empty, adding nothing to an assertion except to convert its use to its mention. That is, the predicate " is true" merely asserts the proposition contained in the sentential clause to which it is applied but does not ascribe any additional property to that proposition or sentence, and in Ramsey's British lexicon, "is true" is redundant. Hence, redundancy theory of truth claims that the whole issue of truth is an illusion, caused by our use of the predicate "is true" which allegedly is redundant, i. e without meaning.

A variant of redundancy theory is the disquotational theory, which uses a modified form of Tarski's T schema: To say that P' is true" is to say that P. Yet another version of deflationism is the prosentential theory of truth, first developed by Dorothy Grover, Joseph Camp, and Nuel Belnap as an elaboration of Ramsey's claims. They argue that sentences like "That's true", when said in response to "It's raining", are prosentences (see pro form), expressions that merely repeat the content of other expressions. In the same way that it means the same as my dog in the sentence My dog was hungry, so I fed it, That's true is supposed to mean the same as It's raining—if you say the latter and I then say the former. These variations do not necessarily follow Ramsey in asserting that truth is not a property, but rather can be understood to say that, for instance, the assertion "P" may well involve a substantial truth, and the theorists in this case are minimalizing only the redundancy or prosentence involved in the statement such as "that's true." Proponents of pragmatic, constructivist and consensus theories would differ with all these conclusions, however, and instead assert that the second person making the statement "that's true" is actually participating in further verifying, constructing and/or achieving consensus on the proposed truth of the matter—e. g., the proposition that "it's raining". Redundancy theory does not apply to representations that are not analogous to sentences and they do not apply to many other things that are commonly judged to be true or otherwise. Consider the analogy between the sentence "Snow is white" and the person Snow White, both of which can be true in a sense. To say Snow is white' is true" is to say "Snow is white", but to say "Snow White is true" is, obviously, not to say "Snow White."
