[catalogued under 7. Existence / C. Structure of Existence / 5. Supervenience / c. Significance of supervenience]

Full Idea

Some entailments do not suffice for supervenience. Being a brother entails being a sibling, but being a sibling does not supervene on being a brother. Sarah has a sister and Jack in an only child. Sarah, unlike Jack, is a sibling; neither is a brother.

Gist of Idea

Some entailments do not involve supervenience, as when brotherhood entails siblinghood

A Reaction

The whole point of supervenience, I take it, is to label a relation of tracking, while offering no explanation of the tracking. Entailment would be a rather powerful explanation, as would a dog's being tied to a cart.
