Causation is a source of confusion in tort theory, as well as a flash point between consequentialist and deontological legal theorists. Consequentialists argue that causation is generally determined by the policy grounds for negligence, not by a technical analysis of the facts. Conversely, deontologists reject the view that policy motives determine causation findings. Causation has also generated different approaches within the consequentialist school. In this chapter I try to bring some order to the arguments on causation by isolating key elements of the cases and introducing a "causation tree" that highlights the role of information. A better model of causation may help to resolve the arguments between different schools of tort theory, and to reconcile conflicting models within the consequentialist school.
