The Causal and Unification Approaches to Explanation Unified—Causally

Two major modern accounts of explanation are the causal and the unification accounts. My aim in this paper is to provide a kind of unification of the two, by using the central technical apparatus of the unification account to solve a central problem faced by the causal account, namely, the problem of determining which parts of a causal network are explanatorily relevant to the occurrence of an explanandum. The result is a causal account of explanation that has many of the advantages of the unification account.
