9014 | Some conditionals can be explained just by negation and conjunction: not(p and not-q) [Quine] |
Full Idea: Often the purpose of a conditional, 'if p, q', can be served simply by negation and conjunction: not(p and not-q), the so-called 'material conditional'. | |
From: Willard Quine (Philosophy of Logic [1970], Ch.2) | |
A reaction: Logicians love the neatness of that, but get into trouble elsewhere with conditionals, particularly over the implications of not-p. |
