Natural evil

Natural evil, or surd evil, is a term generally used in discussions of the problem of evil and theodicy that refers to states of affairs which, considered in themselves, are to be avoided and not to be promoted, and for which no agent is morally responsible. It stands in contrast to moral evil.

Nature of natural evil

Moral evil results from a perpetrator, or one who acts intentionally and in so doing has flouted some duty or engaged in some vice. Natural evil has only victims, and is generally taken to be the result of natural processes. The "evil" thus identified is evil only from the perspective of those affected and who perceive it as an affliction. Examples include cancer, birth defects, tornadoes, earthquakes, tsunamis, hurricanes, acts of god, and other phenomena which inflict suffering with apparently no accompanying mitigating good. Such phenomena inflict "evil" on victims, but with no human perpetrator to blame for it.

Natural or moral evil?

Jean Jacques Rousseau responded to Voltaire's criticism of the optimists by pointing out that the value judgement required in order to declare the 1755 Lisbon earthquake a natural evil ignored the fact that the human endeavour of the construction and organization of the city of Lisbon was also to blame for the horrors recounted as they had contributed to the level of suffering. It was, after all, the collapsing buildings, the fires, and the close human confinement that led to much of the death.

The question of whether natural disasters such as hurricanes might be natural or moral evil is complicated by new understandings of the effects, such as global warming, of our collective actions on events that were previously considered to be out of our control. Certain such disasters, however, such as damage caused by a meteorite, cannot be ascribed to the actions of humans.

Another common argument, espoused by Alvin Plantinga, is that everything that appears at first glance to be natural evil could in fact be moral evil committed by freely acting supernatural beings, such as fallen angels.
