Impossible Worlds and the Intensional Sense of ‘And’ [Special Issue]

In this paper I show that the ‘and’ in an argument like Lewis’ against concrete impossible worlds cannot be simply assumed to be extensional. An allegedly ‘and’-free argument against impossible worlds employing an alternative definition of ‘contradiction’ can be presented, but besides falling prey of the usual objections to the negation involved in it, such ‘and’-free argument is not quite so since it still needs some sort of premise-binding, thus intensional ‘and’ is needed and that suffices to block the argument at a stage prior to the steps about negation.
