Single Idea 18680
[filed under theme 7. Existence / C. Structure of Existence / 5. Supervenience / a. Nature of supervenience
]
Full Idea
It is no part of supervenience that 'if p then q' entails 'if not p then not q'. To avoid such misunderstandings, it is common (though not more accurate) to describe supervenience in negative terms: no difference in A without a difference in B.
Gist of Idea
To avoid misunderstandings supervenience is often expressed negatively: no A-change without B-change
