 The mixed theory has two problems. This sentence combines (4) and (5) in a conditional sentence but since the consequent is taken to express an attitude it is unclear how it should be understood. This is because one can assert (6) without expressing the attitude in (5); one might, for example, think that the antecedent and consequent are false but nevertheless think that (6) is true because if the antecedent were true then the consequent would be true. It seems, therefore, that if the mixed theorist is right that (5) expresses a non-cognitive attitude then it must have a different meaning in (6) where it is not tied to the expression of any attitude. This brings us to a second problem, which is that (4) and (6) together entail (5). Together these sentences make an evidently valid modus ponens argument. However, if (5) means something different when asserted and when embedded in the conditional (6), then this argument is invalid. More generally, the mixed theory looks in difficulty when trying to explain the meaning of conditionals or valid arguments that contain expressive and cognitive religious sentences.
