7. Existence / C. Structure of Existence / 5. Supervenience / a. Nature of supervenience

3536	Supervenient properties must have matching base properties [Kim]
	Full Idea: Each supervenient property necessarily has a coextensive property in the base family.
	From: Jaegwon Kim (Concepts of supervenience [1984], §5)
	A reaction: This is presumably the minimum requirement for a situation of supervenience. How do you decide which property is the 'base' property? Do we just mean that the base causes the other, but not vice versa?

7. Existence / C. Structure of Existence / 5. Supervenience / c. Significance of supervenience

4242	Pure supervenience explains nothing, and is a sign of something fundamental we don't know [Nagel]
	Full Idea: Pure, unexplained supervenience is never a solution to a problem but a sign that there is something fundamental we don't know.
	From: Thomas Nagel (The Psychophysical Nexus [2000], §III)
	A reaction: This seems right. It is not a theory or an explanation, merely the observation of a correlation which will require explanation. Why are they correlated?
