Jeffrey Jay Lowder on logical arguments from evil.
According to logical arguments from evil, some known fact about evil is logically incompatible with God's existence. (In contrast, evidential arguments from evil merely claim that some known fact about evil is evidence for God's nonexistence.) Ever since Alvin Plantinga rebutted J. L. Mackie's logical argument from evil, the majority of contemporary philosophers of religion have come to believe that logical arguments from evil are unsuccessful. This opinion is not unanimous, however. Philosophers Richard Gale, Quentin Smith, and Howard Jordan Sobel challenge the conventional view regarding the prospects for logical arguments from evil. Indeed, Smith has formulated a new version of the logical argument from evil to avoid the pitfalls of Mackie's argument. Nevertheless, many philosophers remain highly skeptical regarding logical arguments from evil.
