According to Gauker an argument is valid if the conclusion is assertible inevery context in which the premises are assertible. This runs counter to whatGauker sees as a systematic misreading of the data by other authors who judgearguments to be invalid if they can think of a context in which the premisesare judged true and some other context in which the conclusion is judged false.Different schools of thought on conditionals reflect fundamentally differentapproaches to semanties. Gauker offers his theory as a motive and test case fora distinctive kind of semanties that dispenses with reference relations andpossible worlds. «
