Our notion of validity in classical logic seems to yield some unintuitive results, one of which is that known as EFQ, ex falso quodlibet. In this paper I examine Read’s solution to EFQ. Read argues that some rules of inference such as addition or disjunctive syllogism are not valid. I show that he does not succeed in establishing the invalidity of those rules.
