Emergence and Reflexive Downward

Abstract

This paper responds to Jaegwon Kim's powerful objection to the very possibility of geninely novel emergent properties. Kim argues that the incoherence of reflexive downward causation means that the causal power of an emergent phenomenon is ultimately reducible to the causal powers of the causal powers of its constituents. I offer a simple argument showing how to claracterize emergent properties in terms of the effects of structural relations on the causal powers of their constituents.
