Multiple Realizations and the Metaphysics of Reduction
Multiple Realizations and the Metaphysics of Reduction
Jaegwon Kim has argued against non-reductive physicalism on the justification that it defies the causal closure of the physical. Causal closure is actually a metaphysical theory regarding the nature of causation in the physical sphere with considerable implications in the study of the mind. Generally, the concept is that physics endows with complete clarification of physical events. If mental properties are efficacious causally then they have to be either identical to physical properties, or there should be widespread over determination.
