The rational consequence relation is non-monotonic, and the relation is intended to carry the meaning theta usually implies phi or phi usually follows from theta.In this sense it is more useful for modeling some everyday situations than a monotone consequence relation because the latter relation models facts in a more strict boolean fashion—something either follows under all circumstances or ...
Tautological consequence can also be defined as ∧ ∧ ... ∧ → is a substitution instance of a tautology, with the same effect. [2]It follows from the definition that if a proposition p is a contradiction then p tautologically implies every proposition, because there is no truth valuation that causes p to be true and so the definition of tautological implication is trivially satisfied.
The Psychological Consequences of Money Kathleen D. Vohs,1* Nicole L. Mead,2 Miranda R. Goode3 Money has been said to change people’s motivation (mainly for the better) and their behavior toward others (mainly for the worse). The results of nine experiments suggest that money brings
Lying in a court of law, for instance, is a criminal offense . [37] Hannah Arendt spoke about extraordinary cases in which an entire society is being lied to consistently. She said that the consequences of such lying are "not that you believe the lies, but rather that nobody believes anything any longer.
Due to the ability to speak about non-logical individuals along with the original logical connectives, first-order logic includes propositional logic. [ 7 ] : 29–30 The truth of a formula such as " x is a philosopher" depends on which object is denoted by x and on the interpretation of the predicate "is a philosopher".
