|David K. Lewis: a thought experiment concerning two omniscient gods (omniscient with respect to propositions). None of them knows who he is because that is not comprehensible in propositions. Self-knowledge is not propositional knowledge. (D.K. Lewis Philosophical Papers Vol. I 1983, p 139ff)|

Two omniscient gods / Example/ Lewis: omniscient: only through knowledge of all propositions - but incapable of self-ascribe the decisive properties, since properties (attributes) are not propositional - CatanedaVsLewis: his notion of the unique counterpart fits more to the part-subject areas of private objects - the overlapping structure would be a total world, and each extension would be "my World" for every person in the world. Therefore, Lewis Example of the two Gods is not evident, even not if we equate propositions with sets of possible worlds.
