 Let us step back from some of the particular commitments in Perry’s presentation of the case to extract an argument that both Perry and Lewis could endorse: There’s something theoretically and explanatorily important that Hume and Heimson have in common. But it’s not a state of believing P for any traditional proposition P. (If it was, either both would be correct in their belief or neither would.) To capture this doxastic similarity, we need resources beyond those provided by the Simple Picture. We need states of distinctively self-locating belief.
