Multiple Realizability - Kim's Argument

Kim's Argument

Jaegwon Kim has recently argued against non-reductive physicalism on the grounds that it violates the causal closure of the physical. Roughly, the idea is that physics provides a full explanation of physical events. If mental properties are causally efficacious, they must either be identical to physical properties, or there must be widespread overdetermination. The latter is often held to be either unlikely or even impossible on conceptual grounds. If this is right, then the options seem to be either reduction or elimination.
