Single Idea 15293

[catalogued under 14. Science / D. Explanation / 1. Explanation / c. Direction of explanation]

Full Idea

Natural necessity involves causal directionality as an essential element, while entailment as a purely logical relation does not.

Gist of Idea

If explanation is by entailment, that lacks a causal direction, unlike natural necessity

A Reaction

If there is a naturally necessary relation between an eclipse and its cause, the directionality of that doesn't seem to arise from the mutual relation between the two. You have to add time's arrow, or causation's arrow.
