See also judgment, truth theory, truth definition, deflationism, minimalism, disquotationalism, all that he said is true, predication.|

Redundancy theory / Tugendhat: there is a surplus in the expression ’p’ incomparison to the incomplete expression ’that p’ - it is this plus that the addition of ’is true’ expressed - that is not at all trivial. - It would be trivial if one presupposes that one already understands the use of assertoric sentences - "true" can be eliminated - (Tugendhat per redundancy theory)
