[catalogued under 14. Science / D. Explanation / 2. Types of Explanation / d. Lawlike explanations]

Full Idea

All animals with a liver also have a heart; so we can deduce from this plus the existence of Fido's liver that he also has a heart, but his liver does not explain why he has a heart.

Gist of Idea

Livers always accompany hearts, but they don't explain hearts

A Reaction

This is a counterexample to Hempel's deductive-nomological view of explanation. It seems a fairly decisive refutation of any attempt to give a simple rule for explaining things. Different types of explanation compete, and there is a subjective element.
