tautologyIn logic, a statement that cannot be denied without inconsistency. Thus, “All bachelors are either male or not male” is held to assert, with regard to anything whatsoever that is a bachelor, that it is male or it is not male. In the propositional calculus, even complicated symbolic expressions such as [(A ⊃ B) ∧ (C ⊃ ¬ B)] ⊃ (C ⊃ ¬ A) can be shown to be tautologies by displaying in a truth table every possible combination of T (true) and F (false) of its arguments A, B, C. A tautology can be purely formal (a statement form rather than a statement), and in some usages only such formal truths are tautologies. tautology Logic a statement that is always true, esp a truth-functional expression that takes the value true for all combinations of values of its components, as in either the sun is out or the sun is not out

His is a philosophical humor that relies on tautologies and clashing contrasts, inspired equally by Duchamp and Wittgenstein. To make matters worse, in his attempt to work out his conception of 'worldview' from the Kantian synthetic a priori, Acikgenc falls into tautologies, circularities, conceptual gaps, inconsistencies and contradictions too numerous and tedious to exhaust in any detail here. The continued use of categories such as eschatology or apocalyptic to describe New Testament data simply indicates that too many scholars are stuck in nineteenth-century tautologies that no longer produce the scientific self-evidence they did in the past. |
