2329 | Causal power is a good way of distinguishing the real from the unreal [Kim] |
Full Idea: A plausible criterion for distinguishing what is real from what is not real is the possession of causal power. | |
From: Jaegwon Kim (Mind in a Physical World [1998], §4 p.119) | |
A reaction: This is, of course, a physicalist view, but for physicalists it is probably the best criterion of what is real. A standard objection to platonism in mathematics is that it denies mathematics causal powers. |
