On the Constitutive Property Reply: Commentary on Campbell



For the nonreductive physicalist, behavioural effects have a complete physiological explanation and a distinct psychological explanation. In a series of papers Jaegwon Kim argues that there can be no more than a single complete and independent explanation of any one event, thereby excluding the psychological explanation. For his own part, Kim includes psychological explanations through the use of an extensional model of explanatory individuation. Numerous critics have pointed out the counterintuitive results of this extensional model of explanatory individuation. In a recent article in this journal, Neil Campbell suggests that Kim's property exemplification account of events provides the conceptual resources to dodge this objection. In this article I argue that this appeal to the property exemplification account does not work in the crucial case of mental explanation.
