 Suppose we call physicalism so defined fundamentality physicalism; what is the relation between it and supervenience physicalism? Supervenience physicalism does not entail fundamentality physicalism, since the fact that a property F supervenes on a property G does not entail that either property is fundamental. Nevertheless, it is reasonable to think that fundamentality physicalism entails supervenience physicalism, especially in the light of Lewis’s comment about supervenience just quoted.
