ABSTRACT
Karttunen (1977) within the framework of Montague (1973).11 Karttunen claimed that there is a basic difference between the two in that on his analysis questions denote sets of propositions that are true answers, not all possible answers, to them. (More accurately, Karttunen's analysis yields sets of all true propositions that correspond to the question or else, if there are no such true propositions, the empty set.12) But, as noted by G&S (1984, ch.l, n.38), there is really no substantive difference: since Hamblin's denotation-set for a proposition is a set of sets of worlds, it is a straightforward matter to single out, at any world w;, the propositions which are true at w;: simply collect together the subsets of the denotation-set of which w; is a member. So for a given question evaluated at a given index, Hamblin's and Karttunen's analyses yield the same set of propositions.13
