The Puzzle of the Absent-Minded Driver is Not about Absent-Mindedness, but about Indexical Belief

  • Wolfgang Spohn

摘要

This paper does not add a novel solution or a novel justification for an existing solution of the puzzle of the absent-minded driver. Rather it wants to set existing solutions into the right perspective. It argues that the puzzle is not about absent-mindedness at all, but about indexically presented indistinguishable alternatives. It identifies a common assumption as one about the relation between beliefs about indexical and non-indexical propositions. So, this is what is involved in the puzzle. This assumption entails the favorite solution of the puzzle and is stated as a general a priori symmetry principle for indexical propositions.
