사건과 사건 사이의 관련성은 판단에 잘 사용하지만 사건과 사건없음의 관련성에는 주목하지 못한다. 무사함의 원인에 대해 분석도 필요함
Causality (also called causation, or cause and effect) is influence by which one event, process, state, or object (a cause) contributes to the production of another event, process, state, or object (an effect) where the cause is partly responsible for the effect, and the effect is partly dependent on the cause. In general, a process has many causes, which are also said to be causal factors for it, and all lie in its past. An effect can in turn be a cause of, or causal factor for, many other effects, which all lie in its future. Some writers have held that causality is metaphysically prior to notions of time and space.
