Physicalism, Foundationalism, and Infinite Descent

Abstract

AbstractThis paper contributes to answering the question how physicalism can be defined for a world without fundamental physical phenomena. In a recent paper in this journal, Torin Alter, Sam Coleman, and Robert J. Howell propose a necessary condition on physicalism. They argue that physicalism is true only if there is no infinitely descending chain of mentally constituted phenomena. I argue that this alleged necessary condition faces counterexamples. An infinitely descending chain of mentally constituted phenomena is compatible with physicalism. Afterwards I propose a simpler definition of physicalism that does not fall prey to my counterexample.
