Read some of this: Stenius’ vacuous text, Hintikka’s interesting proposition to define candidates for quantification as what can be looked for in some sense, Chomsky’s vastly inaccurate criticism, Sellars’ fascinating, but ultimately pointless, proposition to quantify into modal, and other opaque contexts, if we allow ourselves to use individual concepts (roughly, senses), which is precisely what Quine wants to do without (and differently from Hintikka, who reduces the difference between opaque and transparent uses of intensional verbs to the extension of their possible objects, viz. does it range over what X knows, or over what he doesn’t know, whereas Sellars maintains an *intensional* difference between the two senses of the intensional verb—believes eg). And then I also read Kaplan’s article; I did like immensely the idea that we can put in referential position something that is actually in an opaque context, but the rest of the article went a bit over my head, because I had to get to work so I didn’t read it closely enough.
