A Problem Emerges: or, why Nonreductive Materialism and Emergentism Face the Same Set of Insourmountable Problems

Jaegwon Kim, in his superb essay The nonreductivists troubles with mental causation (from the volume Supervenience and Mind), argues that nonreductive materialism (NRM) and emergentism (E) have the same cash value. He identifies four key theses that NRM is committed to: (1) all concrete particulars are physical (2) mental properties are not reducible to physical properties (3) all mental properties are physically realized and (4) mental properties are real properties of objects and events. Kim finds that E is committed to the same four theses: E accepts a materialist ontology (1), accepts that emergent properties are not reducible to their ‘basal conditions’ (2), accepts that higher-level or emergent properties need a physical base; this physical base is itself sufficient for the emergence of these properties (3) and finally, E accepts realism about the mental (4). These agreements are sufficient to show that NRM and E are, more or less, the same thing. Thus, any problems had by one are had by the other. Should NRM face an insurmountable difficulty, E will as well, and should E face its own insurmountable difficulty, then NRM also will. Continue reading
