 Legal theory, like philosophy, has had its share of skeptics about causation. Most of such legally located skepticism has been directed at the proximate cause half of the conventional two-part definition of causation in the law. As we shall see shortly, such skepticism there considers “proximate cause” a misnomer and reinterprets the proximate cause requirement in noncausal, policy terms. More radical is the skepticism here considered. Some legal theorists are skeptical of there being any natural relation in the world named by “causation”. This skepticism includes what the law names “cause in fact” as well as “proximate cause”.
