Intention, Action, and De Se Indexicality

The view that first-person (de se) mental content is essential to the explanation of action in general is a strong essential indexicality thesis. A weaker essential indexicality claim is that de se mental content is an essential ingredient of intentional action. An argument by Bermudez for the former thesis and an argument from Babb in support of the latter are discussed in Section 2, and for reasons presented there it seems that both arguments are unsound and the conclusions are false as well. However, the discussion of their arguments helps us identify a certain class of intentional action, and an apparently very large class, the members of which are guaranteed to have de se origin. This class of intentional action is identified in Sections 3 and 4 and it is shown that necessarily, any member of this class has its origin in indexical, specifically, de se mental content.
