I<br /><br />In philosophy, "P entails Q" means "There is no possible world where P is true and Q is false." The philosophical meaning of entailment doesn't quite match the ordinary English definition, since in the philosophical sense "The existence of a married bachelor entails two plus two equal four" is true, but it is apparently not true in the ordinary English sense.<br /><br />Similarly, in the philosophical sense "imply" is potentially much weaker than what you've described here, since it is often used to refer to material implication, i.e. where "P implies Q" just means "It is not the case that P is true and Q is false." For example, "Abraham Lincoln never being President of the United States implies that he was a disc jockey" is true.Maverick Christianhttps://www.blogger.com/profile/04286456663634536819noreply@blogger.com
