6155 | Supervenience is a one-way relation of dependence or determination between properties [Rowlands] |
Full Idea: Supervenience is essentially a one-way relation of dependence or determination, …which holds, in the first instance, between properties. | |
From: Mark Rowlands (Externalism [2003], Ch.2) | |
A reaction: This definition immediately shows why supervenient properties are in danger of being epiphenomenal (i.e. causally irrelevant). Carefully thought about the notion of a 'one-way' relation will, I think, make it more obscure rather than clearer. |
