Unnecessary Causation.

The causation question and the suggested answer

At common law the question of causation is fundamental. But, as is often acknowledged, the basic question of causation is not a question of law: it is commonly described, in a misleading expression, as ‘causation in fact’. The true causal question is not actually one of fact. It is one of metaphysics. It involves asking when an outcome (O) is caused by an event (E).
