Concept

Skeptical Theism

Intro

The strongest atheist argument against God is the problem of evil: a good and powerful God would not allow horrific suffering, this kind of horrific suffering exists, therefore God either is not good or is not powerful or does not exist. The version that does the most work in serious philosophy is the evidential version, which says, "I can think of no possible reason God could have for letting this child die of cancer; therefore probably there is no such reason; therefore probably God is not the kind of being who would allow it."

Skeptical theism is a Christian response to that argument. It does not try to name God's reasons. It does not say cancer is good. It does something humbler and harder for the atheist to defeat: it asks a question about the inference.

The inference is: "I see no reason; therefore probably no reason exists." Logicians call this a no-see-um inference, you do not see one, so probably there is not one. Sometimes that inference works. If I look hard for an elephant in my living room and do not see one, there probably is not one. The inference works because if there were an elephant there, I would see it.

But the inference fails when what you are looking for is the kind of thing you would not be able to see anyway. If I look hard for invisible bacteria in my living room and do not see them, my failure to see them tells me almost nothing. They are below my detection range.

Skeptical theism asks: are God's reasons for permitting evil the kind of thing finite minds could detect? Probably not. The gap between an infinite, all-knowing intellect aware of every chain of consequences across all of history, and a creature whose perspective is one life on one planet for a few decades, is so vast that most of the morally relevant reasons would simply lie outside our access. Not seeing one is what you would expect either way, whether God exists or not. The no-see-um inference fails.

This does not prove God exists. It blocks the strongest version of the atheist argument from disproving God. It keeps the question open and forces the debate to other grounds. The position has been developed since the 1980s by Stephen Wykstra, William Alston, and Michael Bergmann. Critics like Stephen Maitzen argue it works too well and slides into a wider moral skepticism. The page below walks the formal technical work (Wykstra's CORNEA principle), the major objections, and the related applications to divine hiddenness arguments. It is one of the most important contemporary defensive moves in the philosophy of religion.

In full

The contemporary apologetic move that addresses the evidential problem of evil (and adjacent objections like divine hiddenness) by invoking human cognitive limitation with respect to detecting morally-justifying reasons. The core thesis: even if we cannot identify a morally-sufficient reason why God permits some particular evil E, the inference from I see no reason for E to there is no reason for E is not warranted given (a) the vast asymmetry between human cognitive resources and an infinite divine intellect, and (b) general epistemological principles about when "no-see-um" inferences are reliable. Skeptical theism therefore blocks the inferential move that powers evidential-POE arguments without requiring positive identification of the reasons God might have. Major proponents: William Alston ("The Inductive Argument from Evil and the Human Cognitive Condition," 1991), Stephen Wykstra (the original CORNEA principle, 1984), Michael Bergmann (Justification without Awareness 2006; multiple papers), Daniel Howard-Snyder. Major critics: Stephen Maitzen (2009), Trent Dougherty (sympathetic critic), argue skeptical theism collapses into wider moral skepticism. The position is load-bearing across evidential-POE engagements (Problem of Evil; Divine Hiddenness; Atheism §grounding-problem).

The thesis

Skeptical theism distinguishes:

Ontological claim, there exists pointless evil (gratuitous evil, evil for which God has no morally-sufficient reason).
Epistemic claim, we can detect that some evil is pointless.

The standard evidential-POE argument depends on (2): Rowe-style arguments move from "we cannot identify any reason God could have for permitting [horrific case E]" to "probably there is no reason." Skeptical theism rejects the inference from (2): we cannot reliably move from I see no reason for E to there is no reason for E given the radical asymmetry between human cognitive resources and divine omniscience.

The position does not commit to (1) being false. Skeptical theism is epistemically defensive, it blocks the atheist's inferential move without requiring the theist to positively identify God's reasons.

The CORNEA principle (Wykstra 1984)

Stephen Wykstra's "Condition of Reasonable Epistemic Access" (CORNEA) is the foundational technical articulation:

A subject S can reasonably claim "p is the case from what I can tell" only if it is reasonable for S to believe that, if p were not the case, this likely would have shown up given what S has access to.

Applied to POE: the atheist Rowe-style claim "there is no morally-sufficient reason for evil E from what I can tell" is reasonable only if "if there were such a reason, it likely would have shown up given my access." But:

Human moral perception is shaped by limited time-horizons, limited cognitive resources, limited awareness of metaphysical considerations relevant to divine value-making.
If there were a morally-sufficient reason for E, it would not necessarily show up to human moral perception, many morally-relevant considerations are accessible only with extensive temporal-and-cognitive resources, complete information about counterfactuals, etc.
Therefore the CORNEA condition fails for the Rowe-style premise, and the inference "I see no reason → there is no reason" is not warranted.

Wykstra's classic analogy: the chess novice watching a grandmaster's move that looks pointless. The novice's failure to see the move's purpose is no evidence that the move has no purpose; the novice lacks the chess-cognitive-resources to detect the purpose if one is present.

Three lines of argument for skeptical theism

1. Cognitive-asymmetry argument

The simplest argument: humans are finite cognitive beings; God (if exists) is infinite. The asymmetry is not just quantitative (more knowledge) but qualitative (access to all relevant counterfactuals, all causal chains, all moral relations across all of history). Given this asymmetry, the human inability to identify a justifying reason for E provides weak evidence about whether such a reason exists.

Proponents: Alston 1991; Bergmann 2006; Howard-Snyder. The argument operates on the modesty-of-human-cognition grounds shared with much of mainstream epistemology.

2. Track-record argument

We have track-record evidence that human moral judgment about distant or large-scale matters is unreliable. Examples: 19th-c. moral judgments about race; medieval moral judgments about heresy-execution; Greco-Roman moral judgments about slavery. In each case, considered moral judgment of the period was strongly convinced of moral propositions that subsequent reflection revealed to be false.

If our moral judgment is this unreliable about human-scale moral matters with full access to the relevant facts, our judgment about cosmic-scale moral matters where God's vantage encompasses considerations we cannot access is even less reliable.

3. Probability-theory argument

Bergmann's particular contribution: even granting Bayesian frameworks, the prior probability that we would be able to identify all morally-sufficient reasons God might have is low, given the cognitive-asymmetry. Therefore the evidential-POE argument's posterior probability against theism is correspondingly weak, the failure to identify reasons does not raise atheism's probability significantly.

Apologetic deployment

1. Against Rowe's evidential argument from evil

William Rowe's classic evidential POE (the fawn-burning-in-the-forest example, The Problem of Evil and Some Varieties of Atheism 1979): probably God does not exist, given the apparent gratuitousness of horrific evil cases.

Skeptical theist response: the inference from apparent gratuitousness to actual gratuitousness fails the CORNEA condition. Without the inference, the evidential-POE argument is blocked.

2. Against the divine-hiddenness argument

J. L. Schellenberg's Divine Hiddenness and Human Reason (1993) argues that the existence of non-resistant non-believers is evidence against the existence of a perfectly-loving God (who would supposedly make himself known to all who are open to him).

Skeptical-theist response: the inference from I see no reason God would permit non-resistant non-belief to God has no reason fails the CORNEA condition. Multiple Christian-apologetic responses (free-will-formation, soul-making, idolatry-prevention per Dumsday, saving-faith-formation per Moser/Stump) supply candidate reasons; even if those particular candidates fail, the inferential blockage holds. See Divine Hiddenness.

3. Against the moral-evil objections

The OT-difficult-text objection family (Canaanite Conquest and Herem; God and the Killing of Children; etc.) often deploys variant forms of the evidential-POE inference: "I see no reason God could have for X" → "there is no reason." Skeptical theism blocks this inferential pattern as a general apologetic-deployment strategy across the OT-difficult-text family.

4. The Job-paradigm

Skeptical theism finds biblical anchor in Job 38-41, God's response to Job's complaint is not to justify the suffering by listing the reasons but to display the cognitive-asymmetry between divine and human standpoints. "Where were you when I laid the foundations of the earth?... Have you seen the springs of the sea?... Will you discredit my justice?... Will you condemn me to justify yourself?" The Job-paradigm is the canonical biblical articulation of the skeptical-theism move: God's response to the POE-problem is not to give the justifying reasons but to re-frame the standpoint from which justification is evaluated.

Major objections to skeptical theism

Objection 1, Moral skepticism slippery slope (Maitzen 2009; Almeida & Oppy 2003)

If we cannot reliably move from "I see no reason for E" to "there is no reason for E" in cosmic-providential cases, then the same skepticism should apply to ordinary moral cases: "I see no reason God would prevent the Holocaust" cannot be ruled out by "I see no Holocaust-justifying reason." But that seems to license appalling conclusions: we cannot say that the Holocaust was a gratuitous evil; we cannot rule out that God had a sufficient reason; we therefore cannot draw moral conclusions from cosmic suffering.

Maitzen and others argue this collapses skeptical theism into a wider moral skepticism that vitiates all moral judgment.

Response (Bergmann + Howard-Snyder): The slippery slope is not as steep as charged. Skeptical theism's cognitive-asymmetry premise concerns cosmic-providential cases where the divine vantage's access to counterfactuals + universal-causal-chains is the relevant difference. Ordinary-moral cases (where a human acts wrongly) do not require the same divine-vantage premises and remain subject to standard moral epistemology. The skeptical-theist position can distinguish first-order moral claims (Hitler's actions were wrong) from cosmic-providential moral claims (God permitted the Holocaust) without inconsistency. The key is whether the case requires divine-vantage information for adjudication.

Objection 2, Trent Dougherty's commonsense problem (2008)

Sympathetic critic Trent Dougherty argues that radical skeptical-theism creates apologetic problems: if skeptical-theism blocks the atheist's evidential-POE move, it equally blocks Christian positive moral claims about God's providence (we cannot positively identify the morally-sufficient reasons either). Christian theology then collapses into a sort of "we don't know what God is doing or why" position that is religiously unsustainable.

Response: Modest skeptical theism (the Bergmann-Howard-Snyder consensus) does not preclude positive Christian theology. The Christian theological tradition (theodicy literature, free-will-defense, soul-making, eschatological-justification) supplies candidate reasons that the skeptical theist accepts while not committing to any particular one being the actual reason. The skeptical-theist move blocks atheist inferences without committing to or precluding positive theological commitments.

Objection 3, Begging-the-question concern

Skeptical theism assumes the cognitive-asymmetry between human and divine, which assumes God exists. This makes the argument question-begging in atheist debates.

Response: Skeptical theism's cognitive-asymmetry premise can be granted for the sake of argument by atheists in evaluating the strength of the evidential-POE move. The atheist who runs Rowe-style arguments has typically already granted (for argument's sake) the kind of God being argued against, a God whose cognitive resources would be infinite. Granting this hypothetical, the cognitive-asymmetry follows. The argument is internal to the dialectic with the atheist's own framing.

Connection to other apologetic moves

Theodicies (positive accounts of why God permits evil), free-will-defense, soul-making (Hick), eschatological-vindication (Stump), Christological-cross (Moser). Skeptical theism is complementary to theodicies, it operates as the epistemic-blocking move while theodicies supply candidate reasons.
Reformed Epistemology (Plantinga's sensus divinitatis + warrant), both share concern with human cognitive limitations and the structure of religious-belief warrant.
Job-paradigm, biblical archetype of the skeptical-theist move.
