Supervenience: Not local and not two-way

Abstract

This commentary argues that Ross & Spurrett (R&S) have not shown that supervenience is two-way, but they have shown that all the sciences, including physics, make use of functional and supervenient properties. The entrenched defender of Kim's position could insist that only fundamental physics describes causal relations directly, but Kim's microphysical reductionism becomes completely implausible when we consider contemporary physics.
