 Perry (1977, 1979) argues that terms such as “I” which are, as he puts it, “essentially indexical”, pose a problem for the traditional Fregean view of belief as a two-place relation between a subject and a proposition (cf. Spencer 2007). Fregean senses are, according to Perry, descriptive and as Perry has argued no description is equivalent to an essential indexical. Consequently, no Fregean proposition can be the thing believed when one believes first-personally. Essential indexicality, if somehow forced into the Fregean mould, means that we must implausibly accept that there are incommunicable senses that only the speaker (or thinker) is in a position to grasp (see García-Carpintero &amp; Torre 2016); cf.Evans 1981; Longworth 2013). D. Lewis goes further than this, arguing, partly on the basis of his much discussed Two Gods example (1979), in which each God knows all the propositions true at their world yet fails to know which of the two Gods he himself is, that the objects of belief are not propositions at all but rather properties (or centred worlds). That is, since they already know all the true propositions, there is no true proposition the Gods would come to believe when they come to realise which God they are. Essential indexicality forces us away from the model of propositions as the objects of belief. Further, Lewis claims that not just the explicitly indexical cases, but all belief is in this way self-locating or, in his terminology, de se. On this account, every belief involves the self-ascription of a property and so, arguably, is an instance of self-consciousness (for discussion, Gennaro 1996: ch. 8; Stalnaker 2008: ch. 3; Feit 2008; Cappelen &amp; Dever 2013: ch. 5; Magidor 2015).
