Full Idea
The Hempelian deductive-nomological model of explanation clearly fits in well with the notion of explanation in terms of coherence. One way of fitting a belief into a system is to show that it is deducible from other beliefs.
Clarification
see under 'Lawlike Explanations' for the Hempel view
Gist of Idea
Deducing from laws is one possible way to achieve a coherent explanation

A Reaction
Smart goes on to reject the law-based deductive approach, for familiar reasons, but at least it has something in common with the Smart view of explanation, which is the one I like.
