 In more recent work (especially, Salmon 1984) Salmon abandoned the attempt to characterize explanation or causal relationships in purely statistical terms. Instead, he developed a new account which he called the Causal Mechanical (CM) model of explanation—an account which is similar in both content and spirit to so-called causal process theories of causation of the sort defended by philosophers like Philip Dowe (2000). We may think of the CM model as an attempt to capture the “something more” involved in causal and explanatory relationships over and above facts about statistical relevance, again while attempting to remain within a broadly Humean framework.
