Skeptical theism is the view that we should remain skeptical of our ability to discern whether our perceptions about evil can be considered good evidence against the existence of the orthodox Christian God. The central thesis of skeptical theism is that it would not be surprising for an infinitely intelligent and knowlegeable being's reasons for permitting evils to be beyond human comprehension. That is, what may seem like pointless evils may be necessary for a greater good or to prevent equal or even greater evils. This central thesis may be argued from a theistic perspective, but is also argued to defend positions of agnosticism.
Skeptical theism can be an informally held belief based on theistic doctrine, but the origin of the term 'skeptical theist' is a 1996 paper by agnostic Purdue Philosopher Paul Drapier, "The Skeptical Theist. Following Draper's publication, the term 'skeptical theism' was adopted in academic philosophy and has developed into a family of positions supporting skeptical theism's central skeptical thesis; we should remain skeptical of claims that human beings can discern God's reasons for evils. One argument is based on analogy, likening our understanding of God's motives to those of a child grasping a parent's reasons for seeking painful medical treatment, for example. Other approaches are the limitations on the human ability to understand the moral realm, and appeals to epistemic factors such as sensitivity or contextual requirements.
In the philosophy of religion, skeptical theism is not a broad skepticism toward human knowledge of God, but is instead putatively presented as a response to philosophical propositions, such as those focused on drawing "all things considered" inductive conclusions about God's motives from perceived circumstances. Additionally, skeptical theism is not a position used to defend all forms of theism, though it is most often presented in the defense of orthodox Christian theism. Moreover, skeptical theism is not supported by all theists and some who support its skeptical positions are not theists.
In philosophy, skeptical theism is a defense of theistic or agnostic positions argued to undercut a crucial premise in the atheology argument from evil, a claim that God could have no good reasons for allowing certain types of evil. It is also presented in response to other atheological arguments claiming to know God's purposes based on circumstances, such as the argument from divine hiddenness .
Argument from evil is an atheological argument asserting that some evils in the world are pointless or gratuitous evils representing evidence against the existence of the orthodox Christian God.
