The Quietest Challenge to the Axiology of God
A Cognitive Approach to Counterpossibles
Guy Kahane asks an axiological question: what value would (or does) God¡¯s existence bestow on the world? Supposing God¡¯s existence is a matter of necessity, this axiological question faces a problem because answering it will require assessing the truth-value of counterpossibles. I argue that Kahane, Paul Moser, and Richard Davis and Paul Franks fail in their attempts to render the axiological question substantive. I then offer my own solution by bringing work in cognitive psychology and philosophy of mind to bear on the possibility of assessing counterpossibles. I argue that humans can engage in counterpossible reasoning by ¡°accepting¡± or ¡°supposing¡± that the antecedent is true and ¡°screening out¡± those beliefs that would result in contradictions when combined in inferences with the acceptance or supposition. These screened out propositions are not treated as false, but are ignored. I offer a three-valued logic for counterpossible reasoning. I conclude by outlining some implications for the axiological question.
