The Essential Indexicality of Intentional Action

Abstract

Cappelen and Dever challenge the widely accepted idea that some key aspect of intentional action is essentially indexical. They argue that the classical arguments for this coming from Perry are in fact arguments for a different phenomenon: the opacity of explanatory contexts. I agree with Cappelen and Dever that what Perry says about the ineliminability of indexical terms from explanations of intentional action fails to amount to an argument for this indexicality being essential. But this should not lead us to be sceptics. In this paper, I present a different argument for the essential indexicality of intentional actions. The key premise of this argument is that intentions themselves are essentially indexical. I provide evidence for this premise and defend it against potential criticism. I also show how the essential indexicality of intentions can be used to vindicate Perry's original claims about the essential indexicality of certain beliefs and desires.
