 According to bivalence,  (8)  must be either true or false. Which is it? Russell’s answer is well known. According to his theory of descriptions  (8)  expresses the conjunction “there is a unique king of France and he is bald” of which the first conjunct is false, and therefore the whole sentence is false. Strawson (1950) however criticized Russell’s analysis and argued that the existence and uniqueness of the king of France is not part of what is asserted by an utterance of  (8)  rather it is part of what is taken for granted or presupposed. If there is no king of France, the sentence is not false, rather it is neither true nor false. Adopting a three-valued logic we can assign to  (8)  value #. Consider now the following three examples where  (8)  occurs in a disjunction.
