 Lawyers and legal theorists alike have an unfortunate penchant for proclaiming that the law is, should be, and must be, autonomous from other disciplines (such as philosophy) in its use of concept like causation (Stapleton 2008; 2015). As Sir Frederick Pollack put it over a century ago, “the lawyer cannot afford to adventure himself with philosophers in the logical and metaphysical controversies that beset the idea of cause” (1901: 36). Yet whether such conceptual autonomy is desirable, necessary, or even possible, presupposes that the law has purposes for its causal requirements that do not dovetail with the metaphysics of causation so studied by philosophy.
