Taking these differences into account, Kripke's controversial analysis of naming as contingent and a priori would, according to Stephen Palmquist, best fit into Kant's epistemological framework by calling it "analytic a posteriori."[iii] Aaron Sloman presented a brief defence of Kant's three distinctions (analytic/synthetic, apriori/empirical, and necessary/contingent), in that it did not assume "possible world semantics" for the third distinction, merely that some part of this world might have been different.[8] ./cache/en-wikipedia-org-2294.html ./txt/en-wikipedia-org-2294.txt
