Abstract
The problem of evil is considered to be the most formidable objection to theism and a central element in the case for atheism. This essay surveys and evaluates the two key formulations of the problem expressed as an argument: the logical argument and the evidential argument. It also analyzes two types of defences offered in response to the argument from evil: the Free Will Defence against the logical argument and Skeptical Theist Defence against the evidential argument. Also treated are several greater-good theodicies that are generally employed as responses to the evidential argument: free will theodicy, natural law theodicy, and soul-making theodicy. Because it sounds a slightly different note from traditional greater good approaches, the theodicy of Open Theism—which argues that the theistic God could create a universe in which there is the possibility of evil occurring that does not serve some greater good—is examined.
