| Tautology, philosophy: A tautology is a statement that is constructed in such a way that it cannot be wrong, because its elements are repeated either affirmatively or negatively, or an exhaustive enumeration of possibilities is spread between which no decision is made. For example, A = A; If A, then A; A or non-A. Tautologies are not informative. See also certainty, information, knowledge, logic, validity, universality, contradiction, truth values, interpretation._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.
