 Cappelen and Dever (2013) present a sustained attack on the constellation of philosophical claims surrounding the “essential indexical”, including its purported relation to action, and both Perry’s and Lewis’s arguments for it (for an alternative objections to Perry and Lewis, see Millikan 1990; Magidor 2015). A central element in their critique is the claim that cases, such as Perry’s shopper, that are often thought to show the special connection between self-consciousness (I-thoughts) and the capacity for action really only show that action explanation contexts do not allow for substitution salva veritate, but rather are opaque (Cappelen &amp; Dever 2013: ch. 3). Just as, if I am at the airport waiting for Jones, I will only signal that man if I believe him to be Jones, so if I am looking for the shopper with the torn sack I will only stop when I believe that I am that shopper. On their view, despite the popularity of the view to the contrary, the capacity for self-consciousness does not possess any philosophically deep relation to the capacity for action.
