Alvin Plantinga's Free Will Defense - Logical Problem of Evil

Logical Problem of Evil

The logical problem of evil emerges from four core propositions:

  1. An all-powerful (omnipotent) God could prevent evil from existing in the world.
  2. An all-knowing (omniscient) God would know that there was evil in the world.
  3. An all-good (omnibenevolent) God would wish to prevent evil from existing in the world.
  4. There is evil in the world.

As J. L. Mackie has highlighted, there would appear to be a contradiction between these propositions such that they cannot all be true. Given that the fourth proposition would appear to be undeniable, it can be inferred from the above that one of the other three must be false, and thus there cannot be an all-good, all-knowing and all-powerful God. To put it another way, if God does exist, He must be either "impotent, ignorant or wicked".

The problem, and various solutions to it, have been debated by philosophers since at least the time of Epicurus in the fourth century BC. One of the most historically significant replies to the problem is the free will theodicy of Augustine of Hippo, which has been extensively criticized.

Famous quotes containing the words logical, problem and/or evil:

    The truth is, that common-sense, or thought as it first emerges above the level of the narrowly practical, is deeply imbued with that bad logical quality to which the epithet metaphysical is commonly applied; and nothing can clear it up but a severe course of logic.
    Charles Sanders Peirce (1839–1914)

    Will women find themselves in the same position they have always been? Or do we see liberation as solving the conditions of women in our society?... If we continue to shy away from this problem we will not be able to solve it after independence. But if we can say that our first priority is the emancipation of women, we will become free as members of an oppressed community.
    Ruth Mompati (b. 1925)

    ... so far from entrenching human conduct within the gentle barriers of peace and love, religion has ever been, and now is, the deepest source of contentions, wars, persecutions for conscience sake, angry words, angry feelings, backbitings, slanders, suspicions, false judgments, evil interpretations, unwise, unjust, injurious, inconsistent actions.
    Frances Wright (1795–1852)
