Problem of Evil

How, if at all, can the existence and severity of moral and natural evil be reconciled with the existence of an omnipotent, omniscient, and perfectly good God?

The Problem of Evil is a family of arguments that claim the existence, extent, or nature of evil is logically incompatible with, or provides strong evidence against, the existence of an omnipotent, omniscient, and perfectly good God (or gods with similar attributes).

Origin
While reflections on suffering and divinity are ancient, the canonical formulation of the "problem of evil" as a logical tension among divine omnipotence, omniscience, and omnibenevolence in light of evil is often traced to Epicurus (via later reports) and was systematically developed in early modern philosophy (e.g., Pierre Bayle, David Hume). The phrase "problem of evil" became standard in 19th–20th‑century anglophone philosophy of religion.

1. Introduction

The problem of evil is a central topic in the philosophy of religion that examines whether, and how, belief in a morally perfect, all-powerful, and all-knowing God can be reconciled with the existence of suffering, wrongdoing, and seemingly unjust states of the world. It functions both as a family of arguments against theism and as a framework within which theists attempt to articulate responses.

These arguments do not focus on evil in a purely moralistic or rhetorical sense, but on a wide range of phenomena: from everyday pain, illness, and natural disasters to genocide, slavery, and what some philosophers term horrendous evils. The problem of evil asks how such realities fit into a world allegedly governed by perfect goodness and sovereign power.

Philosophers typically distinguish between:

  • Logical challenges, which claim that God and evil are strictly incompatible.
  • Evidential challenges, which claim that evil makes God’s existence unlikely.
  • Existential or pastoral concerns, which focus on how sufferers understand God in the midst of affliction.

The entry considers how different traditions and thinkers have framed the tension between divine attributes and evil, and how they have tried either to justify God (theodicies, defenses) or to resist such justification (anti-theodicy, protest). It also surveys non-theistic views that take the prevalence and character of evil to support naturalistic explanations of the world.

The problem of evil intersects with metaphysics (divine attributes and possibility), ethics (moral responsibility and value), epistemology (what humans can know about God’s reasons), and political philosophy (structural injustice and collective wrongdoing), as well as with scientific accounts of nature and human behavior. This entry maps those intersections while remaining focused on the philosophical question of how evil relates to the existence and nature of God.

2. Definition and Scope of the Problem of Evil

The problem of evil is commonly defined as a cluster of arguments claiming that the existence, extent, or character of evil conflicts with, or strongly disconfirms, the existence of an omnipotent, omniscient, and omnibenevolent God. It is not merely the observation that suffering exists, but the perceived tension between such suffering and specific theistic claims.

Dimensions of “Evil”

Philosophers often distinguish:

Type of evilBrief descriptionTypical examples
Moral evilResults from actions or omissions of moral agentsMurder, torture, fraud, oppression
Natural evilNot directly caused by moral agentsEarthquakes, disease, drought, animal predation
Gratuitous evilApparently serves no greater good or purposeA child’s fatal illness with no discernible benefit
Horrendous evilSo extreme it seems to destroy meaning in a lifeGenocide, severe abuse, “soul-crushing” trauma

Arguments about evil may focus on any or all of these categories. Some emphasize the sheer quantity of suffering; others emphasize its distribution (e.g., affecting innocents); still others stress its apparently pointless character.

Logical, Evidential, and Practical Scope

The scope of the problem also varies by argumentative aim:

  • Logical problem of evil: claims that any evil at all is incompatible with the God of classical theism.
  • Evidential (probabilistic) problem: concedes logical compatibility but argues that evil makes God’s existence unlikely.
  • Practical/existential problem: concerns how belief in God can be lived or justified in the presence of suffering, even if philosophical compatibility is granted.

Debates over scope also address whether the problem of evil targets only classical monotheism, or whether it challenges broader conceptions of a morally perfect or providential deity. Some argue that versions of the problem apply to any worldview that posits a powerful, benevolent cosmic order, while others restrict it to doctrines affirming a personal, intervention-capable God.

3. The Core Question: God, Power, and Suffering

At the heart of the problem of evil lies a structural tension among three elements:

  1. The existence of extensive suffering and wrongdoing.
  2. The claim that there exists a God who is omnipotent (all-powerful).
  3. The claim that this God is omniscient (all-knowing) and omnibenevolent (perfectly good).

The core question is how all three can be affirmed consistently.

Classical Formulation

A traditional formulation, attributed (via later reports) to Epicurus and echoed by David Hume, places the tension in interrogative form:

“Is he willing to prevent evil, but not able? then he is impotent.
Is he able, but not willing? then he is malevolent.
Is he both able and willing? whence then is evil?”

— David Hume, Dialogues Concerning Natural Religion (reporting an Epicurean argument)

In more analytic terms, critics often reason:

  • If God is omnipotent, God can prevent any evil.
  • If God is omniscient, God knows about all evils and their consequences.
  • If God is perfectly good, God would want to prevent any evil that is not necessary for some greater good or equally good state.
  • Yet such evils seem to occur.

The central puzzle is whether there can be morally sufficient reasons for God to permit suffering and injustice, given these attributes.

Varied Responses to the Core Question

Different strategies respond to the tension by modifying one or more components:

  • Some retain traditional divine attributes but argue that there are unknown or known justifying reasons for God’s permission of evil.
  • Others reconsider divine power (e.g., denying that omnipotence entails unilateral control over all events) or divine goodness (e.g., interpreting it in non-human-centered or non-moral terms).
  • Still others reject the existence of such a God, taking the tension as evidence against theism.

While subsequent sections develop these strategies in detail, they all orbit this basic question: how can a world so marked by suffering be the creation or domain of a perfectly powerful and perfectly good God?

4. Historical Origins and Ancient Approaches

Ancient discussions did not always use the phrase “problem of evil,” but they addressed related tensions between divine order and suffering, injustice, or apparent chaos.

Greek and Hellenistic Thought

Plato treated evil largely as ignorance or disorder in the soul, subordinate to an overarching rational and good cosmic order. In dialogues like the Republic, injustice and suffering are ultimately harmonized by the soul’s fate beyond this life.

Aristotle affirmed an unmoved mover that is perfect and contemplative but not a providential moral governor. This limited divine involvement reduces pressure to explain specific evils.

Epicureans typically denied providence: the gods, if they exist, are unconcerned with human affairs. The famous Epicurean trilemma (reported later by Lactantius and Hume) uses the reality of evil as an argument against a providential, morally engaged deity.

Stoics understood the cosmos as governed by divine reason (logos). What seems evil is often seen as a necessary part of a rational whole. Suffering can be a stimulus to virtue, and the truly wise person aligns with fate, regarding external misfortunes as indifferent in themselves.

Late Antique and Religious Texts

Plotinus and later Neoplatonists developed a metaphysical hierarchy from the One, treating evil as a privation or lack of good at lower levels of reality rather than a positive principle.

In the Hebrew Bible, texts such as Job, Psalms, and Lamentations wrestle with innocent suffering and divine justice. These writings often emphasize lament, trust, and mystery rather than systematic theodicy. The Book of Job, in particular, foregrounds the protest of a righteous sufferer and a divine response that highlights human cognitive limits.

Zoroastrian traditions present a more dualistic cosmology, with a good, wise deity opposed by an evil spirit. Here, much evil is attributed to a cosmic conflict, mitigating the burden on the good deity’s direct responsibility.

These ancient approaches established key themes—privation, fate, limited providence, protest, cosmic dualism—that later monotheistic and philosophical discussions would refine and contest.

5. Medieval Theodicies and the Privation Theory of Evil

Medieval thinkers within Judaism, Christianity, and Islam developed systematic accounts of how evil could exist under an all-good, all-powerful God, often building on late antique metaphysics.

Privation Theory of Evil

A central medieval theme is the privation theory of evil. Following Augustine and Neoplatonist sources, many argued that evil is not a positive substance but a lack or disorder of good.

  • Augustine of Hippo famously held that all that exists, insofar as it exists, is good; evil arises when wills turn away from the highest good, resulting in a privation of proper order.
  • Thomas Aquinas elaborated this view, distinguishing between metaphysical goodness (being as such) and moral goodness (right order). For Aquinas, God creates only good; evil is a parasitic defect in created goods, especially in the will.

This theory aims to protect God from being the author of evil while preserving divine creation as fundamentally good.

Medieval Theodical Strategies

Medieval theodicies often combined privation theory with appeals to free will and divine wisdom:

ThinkerKey elements of response to evil
AugustineEvil as privation; original sin; misuse of free will by angels and humans as source of moral and some natural evils; greater good of a redeemed order.
BoethiusIn The Consolation of Philosophy, reconciles providence and fate; apparent injustices explained by the limits of human perspective within time.
MaimonidesIn Guide of the Perplexed, classifies evils as self-inflicted, inflicted by others, or natural; emphasizes human ignorance and the limited scope of what counts as genuine evil.
Al-Ghazali and other Islamic theologiansEmphasize God’s sovereignty and wisdom; some stress that what appears evil may serve hidden goods or tests, while debates continue over human freedom and predestination.

These accounts typically affirm that:

  1. God wills good and creates only good.
  2. Evil arises from creaturely limitation or misuse of freedom.
  3. God’s providence orders even evils toward wise purposes, often beyond human ken.

Medieval debates also raise questions about the compatibility of strong divine predestination with genuine human responsibility for evil, tensions that later discussions would revisit.

6. Early Modern Transformations: Bayle, Leibniz, and Hume

In the early modern period, new scientific, theological, and skeptical currents transformed discussions of evil. Three figures—Pierre Bayle, G. W. Leibniz, and David Hume—are particularly influential.

Pierre Bayle: Skeptical Challenge

Bayle’s Dictionnaire Historique et Critique presents the problem of evil as a deep rational challenge to traditional theism. He argues that:

  • The existence of massive suffering and moral corruption is difficult to reconcile with a perfectly good, omnipotent God.
  • Traditional appeals to free will or greater goods fail to explain why God did not prevent particular horrors or create better worlds.

Bayle concludes that human reason seems unable to harmonize evil with classical theism, though he personally maintained faith on fideistic grounds. His work helped crystallize the “problem of evil” as a central philosophical issue.

Leibniz: Best of All Possible Worlds

Leibniz coined the term “theodicy” in Essays on Theodicy, attempting a systematic justification of God:

  • God, being perfectly wise and good, chooses to create the best of all possible worlds, balancing goods, evils, and the laws governing them.
  • Evils are permitted because they are necessary conditions for greater goods, including the orderliness of nature and the existence of free, morally significant agents.
  • Like earlier thinkers, Leibniz treats moral evil as rooted in creaturely freedom and metaphysical evil as a byproduct of finite, limited beings.

Critics have often caricatured this as naïve optimism, but defenders emphasize its sophisticated modal and metaphysical structure.

Hume: Empirical and Dialogical Critique

In Dialogues Concerning Natural Religion and Natural History of Religion, Hume develops powerful objections:

  • Observing the world’s mixture of pleasure and pain, he suggests that its designer, if any, would be at best morally ambiguous, not perfectly good.
  • The scale and randomness of suffering (e.g., natural disasters) are argued to count against traditional theism.
  • Hume questions whether human analogies and reasoning can justifiably infer a morally perfect deity from the empirical world.

These early modern debates shifted focus from purely logical compatibility to empirical evaluation and skepticism about human capacity to justify God’s ways, setting the stage for later logical and evidential formulations.

7. The Logical Problem of Evil and Free Will Defenses

The logical problem of evil asserts that the existence of any evil is strictly incompatible with the existence of an omnipotent, omniscient, perfectly good God. It is presented as a deductive inconsistency claim.

Formal Structure

A typical logical argument runs:

  1. A perfectly good being always eliminates evil as far as it can.
  2. An omnipotent, omniscient being can eliminate all evil.
  3. Evil exists.
  4. Therefore, no such being exists.

Proponents (e.g., J. L. Mackie) argue that, given the divine attributes, there is no possible world in which God and evil coexist.

Free Will Defenses

In response, many theists offer free will defenses, which aim not to explain God’s actual reasons but to show logical compatibility.

The most influential is Alvin Plantinga’s Free Will Defense:

  • Distinguishes between defense and theodicy: a defense only needs a possible explanation.
  • Introduces the idea of significantly free creatures, who can choose between good and evil.
  • Argues that it is possible that even an omnipotent God cannot strongly actualize a world where free creatures always freely choose good, because their free choices are not up to God.
  • Thus, there is at least one possible reason God might permit moral evil: the great good of libertarian free will.

Plantinga also addresses the possibility of transworld depravity, the hypothesis that in every possible world where a given person is significantly free, they perform some wrong action. If such a condition is even possibly true, then God may be unable to create a world with free creatures and no moral evil.

Assessment

Many philosophers— including non-theists—hold that free will defenses successfully undermine the strict logical incompatibility claim, especially regarding moral evil. Debate continues over:

  • Whether the defense adequately addresses natural evil, sometimes linked to demonic freedom or to conditions necessary for free, orderly existence.
  • Whether alternative accounts of divine power and freedom render the defense unnecessary or problematic.

The consensus in much contemporary literature is that the strong logical problem has been largely displaced by evidential formulations, though some still defend or refine logical versions.

8. The Evidential Problem of Evil and Gratuitous Suffering

The evidential (or probabilistic) problem of evil concedes that God and evil may be logically compatible but argues that the nature and amount of evil make God’s existence unlikely.

Rowe’s Formulation and Gratuitous Evil

William Rowe’s influential argument centers on apparently gratuitous evils—cases of intense suffering with no discernible outweighing good or necessary role in a greater plan.

His well-known example is:

  • A fawn trapped in a forest fire, suffering terribly and dying alone, with no human observer or apparent benefit.

Rowe’s reasoning:

  1. There exist instances of intense suffering that an omnipotent, omniscient being could have prevented without thereby losing some greater good or permitting some equally bad or worse evil.
  2. A perfectly good being would prevent any such suffering.
  3. Therefore, probably, no such being exists.

Premise (1) is typically supported by an inference from inscrutability: we see no justifying reason, so it is reasonable to think there is none. This is where the notion of gratuitous evil plays a central role.

Variants and Data Emphasized

Evidential arguments often emphasize:

  • The scale of suffering: genocides, pandemics, widespread poverty.
  • The distribution: severe afflictions falling on children or non-human animals.
  • The pattern: the world does not appear finely tuned to minimize suffering, but rather shaped by indifferent natural processes.

These features are argued to be more probable on a naturalistic hypothesis than on traditional theism.

Responses

Standard responses include:

StrategyCore idea in relation to evidential problem
TheodiciesArgue that many evils are not gratuitous because they are required for greater goods (free will, soul-making, stable natural laws, afterlife compensation).
Skeptical theismChallenges the inference from “no known reason” to “no reason,” citing human cognitive limitations (see Section 10).
Defeater balancingClaims that other evidence for theism (e.g., fine-tuning, moral awareness, religious experience) offsets the evidential force of evil.

Debates focus on whether the cumulative pattern of suffering is better explained by theism with these supplements or by alternative worldviews.

9. Major Theodicies: Free Will, Soul-Making, and Greater-Good

Theodicies attempt to justify God’s permission of evil by proposing actual or likely reasons why an all-good, all-powerful God might allow particular kinds of suffering.

Free Will Theodicies

Free will theodicies extend beyond defenses by claiming that God in fact values creaturely freedom in ways that explain much evil:

  • God creates beings capable of genuine moral responsibility.
  • Such freedom necessarily includes the possibility of misuse, resulting in moral evils like cruelty and injustice.
  • Some versions argue that stable natural laws and a relatively orderly world—conditions for effective action—also make certain natural evils inevitable (e.g., earthquakes in a tectonic world).

Proponents claim that a world with free agents is better than one with merely programmed goodness.

Soul-Making Theodicies

Soul-making (or person-making) theodicies, associated especially with John Hick, reinterpret earthly life as a context for moral and spiritual development:

  • Humans are created in an immature or incomplete state.
  • Evils and challenges (danger, illness, opposition) provide opportunities for virtues like courage, compassion, and perseverance.
  • A world without such difficulties would lack many significant goods of character formation.
  • Often, an eschatological dimension is invoked: the full value of soul-making occurs in an afterlife where sufferings are integrated into a perfected relationship with God.

Critics question whether the severity of many evils is necessary or proportionate for such growth.

Greater-Good and Global Theodicies

Broader greater-good theodicies appeal to a wide array of goods:

Type of good citedExamples of associated theodical reasoning
Aesthetic or global orderSome evils contribute to an overall “beauty” or complexity of the cosmos that would otherwise be impossible.
Regular laws of natureGod maintains fixed natural laws that occasionally result in suffering, because such laws are prerequisites for science, responsibility, and stable interactions.
Afterlife justice and compensationPresent evils are rectified, compensated, and given meaning in a future state.

These theodicies aim to show, not merely that God and evil are compatible, but that there are plausible, morally significant reasons for God to permit the actual distribution of evils we see, though critics contest their adequacy and moral implications.

10. Skeptical Theism and Limits of Human Knowledge

Skeptical theism is a family of positions that use skepticism about human cognitive abilities to resist evidential arguments from evil. Skeptical theists typically affirm both theism and the reality of evil but deny that humans are well placed to judge whether any given evil is gratuitous.

Core Claims

Common skeptical theist themes include:

  • Cognitive disparity: The gap between finite human understanding and divine omniscience is immense; humans occupy a tiny slice of reality in space, time, and informational scope.
  • Complex goods and connections: Many goods, especially those involving long-term histories, free choices, or unknown future outcomes, may be beyond our ken.
  • No-see-um inference critique: The move from “we see no justifying reason for this evil” to “there is no justifying reason” is unreliable in domains where we should expect hidden complexities.

Thus, when evidential arguments point to apparently pointless suffering, skeptical theists contend that we are not epistemically justified in concluding that it is really pointless from God’s perspective.

Arguments and Analogies

Analogies often used include:

  • A small child unable to understand a parent’s painful but medically necessary action.
  • A layperson’s inability to see the rationale behind a complex scientific theory.

These are meant to show that inscrutability does not imply absence of reason.

Criticisms and Internal Debates

Critics argue that skeptical theism may have problematic implications:

Alleged implicationConcern
Moral skepticismIf we cannot assess God’s reasons, can we confidently judge any action as unjust, including our own?
Undermining theism’s positive argumentsIf our cognitive limitations are so severe, do they not also undermine inferences from apparent design, miracles, or moral experience to God?
Practical paralysisIf any apparently horrendous event might be part of a hidden divine plan, does this weaken motivation to prevent suffering?

Skeptical theists respond by attempting to calibrate their skepticism: strong enough to block certain evidential arguments from evil, but not so strong as to collapse ordinary moral reasoning or religious practice. How stable this balance is remains a matter of active debate.

11. Anti-Theodicy, Protest, and Post-Holocaust Thought

Anti-theodicy and protest theism challenge the very project of justifying God’s permission of evil. Rather than offering explanations, they often emphasize lament, resistance, and solidarity with victims.

Anti-Theodicy

Anti-theodicy maintains that attempts to show that horrendous sufferings are necessary or justified can be morally and religiously objectionable:

  • They may appear to instrumentalize victims, treating their suffering as a mere means to others’ goods.
  • They risk trivializing or aesthetically “beautifying” atrocities.
  • They might conflict with practices of mourning and repentance, which acknowledge evil as genuinely horrific rather than rationally subsumed.

Thinkers such as Emmanuel Levinas, D. Z. Phillips, and some liberation theologians argue that faith should not aim to rationalize every tragedy.

Protest Theism

Protest theism affirms God while also affirming the legitimacy—even necessity—of protesting against God in the face of evil:

  • Biblical texts like Job and certain Psalms are interpreted as paradigms of faithful protest.
  • Some Jewish theologians after the Holocaust (e.g., Richard Rubenstein, Elie Wiesel in literary form, and others in more nuanced ways) explore the idea that confronting or accusing God is part of honest covenantal relationship.

In such views, protest does not always entail denial of God’s goodness but may reflect a refusal to domesticate horror through tidy explanations.

Post-Holocaust Theological Reorientations

The Holocaust has been a focal point for rethinking responses to evil:

ApproachBasic orientation
Radical protestSome argue that Auschwitz makes traditional theodicy impossible; God is seen as silent or hidden in a way that defies justification.
Divine sufferingOthers develop the idea of a God who suffers with victims, reframing rather than resolving the problem.
Covenantal crisisEmphasis on the breakdown or transformation of the covenant, rather than on metaphysical theodicy.

These strands share a resistance to presenting the Holocaust as part of a beneficial divine plan. Anti-theodicy and protest thus reshape the discussion: instead of primarily asking how evil can be rationally reconciled with God, they ask how to speak of God at all in the presence of radical suffering.

12. Atheistic and Naturalistic Responses to Evil

Atheistic and naturalistic positions often treat the problem of evil as a key reason to reject the existence of a morally perfect, omnipotent, omniscient God. They typically argue that the world’s evils are more expected on a naturalistic worldview than on theism.

Evil as Evidence for Naturalism

From this perspective:

  • Moral evil is explained in terms of evolutionary biology, psychology, social structures, and individual choice, without appeal to divine permission.
  • Natural evil—earthquakes, diseases, predation—is seen as a byproduct of impersonal physical processes and evolutionary history.
  • The scale, randomness, and apparent pointlessness of many sufferings fit well with an indifferent universe governed by blind laws.

Some atheists contend that appeals to unknown divine reasons are ad hoc compared to the relative simplicity of naturalistic explanations.

Philosophical Atheism and the Problem of Evil

Classical and contemporary atheists (e.g., J. L. Mackie, William Rowe, Paul Draper) develop both logical and evidential arguments from evil as part of a broader case against theism. For instance:

  • Draper formulates hypothesis-testing approaches, comparing the probability of observed pain-and-pleasure data on theism versus on a hypothesis of “indifferent” nature.
  • Others incorporate divine hiddenness alongside evil, arguing that both the world’s suffering and God’s alleged silence jointly support atheism.

Critiques of Naturalistic Accounts

Theistic philosophers raise objections to purely naturalistic treatments of evil:

ConcernQuestion posed to naturalism
Moral realismCan naturalism ground objective moral wrongness, as presupposed by calling some events “evils” rather than mere dislikes?
Existential depthDoes naturalism adequately capture the depth of moral horror, or does it risk reducing suffering to evolutionary or social contingencies?
CounterevidenceDo features such as conscious experience, rationality, fine-tuning, or moral awareness provide offsetting evidence for theism?

Atheistic and naturalistic responses thus form one side of a broader comparative explanatory debate: which overall worldview best accounts for both the existence of evil and other salient features of reality?

13. Intersections with Science: Evolution, Cosmology, and Neuroscience

Scientific developments have significantly reshaped how the problem of evil is framed, especially regarding natural evil and the origins of moral evil.

Evolution and Animal Suffering

Evolutionary biology introduces vast timescales and extensive non-human suffering:

  • Predation, disease, and extinction are integral to natural selection.
  • Mass extinctions and environmental upheavals predate humans by hundreds of millions of years.

This raises questions:

  • Why would a good God employ such a pain-filled process to produce life?
  • How should the suffering of countless animals be evaluated in the context of theodicy?

Some theists respond by appealing to the value of a dynamic, law-governed creation, the intrinsic worth of evolutionary processes, or an eschatological hope that encompasses non-human creatures.

Cosmology and a Vast, Indifferent Universe

Modern cosmology reveals an immense universe:

  • Most of it appears hostile to life.
  • Cataclysmic events (supernovae, gamma-ray bursts) and geological processes can cause immense suffering but are also implicated in making life possible.

These findings can be interpreted in different ways:

Theistic readingsNaturalistic readings
A finely tuned cosmos where harsh conditions are side-effects of laws allowing life.A vast, indifferent universe where life emerges as a contingent byproduct.

The scale and structure of the universe influence how surprising the distribution of natural evils appears under different worldviews.

Neuroscience, Psychology, and Moral Evil

Neuroscience and psychology investigate the roots of aggression, empathy, psychopathy, and bias:

  • Brain structures and neurochemistry correlate with moral behavior and dysfunction.
  • Environmental factors (trauma, deprivation) heavily shape moral capacities.

These insights intersect with philosophical questions:

  • How does biological and psychological constraint affect moral responsibility?
  • Does a naturalistic account of moral dispositions undercut or support theistic explanations of moral evil?

Some theists integrate these findings into free-will-based or soul-making theodicies, while naturalists use them to argue that morality and immorality can be fully understood within a scientific framework, without invoking divine agency.

14. Religious Traditions and Pastoral Responses to Suffering

Beyond abstract argument, the problem of evil shapes how religious communities interpret and respond to suffering through doctrines, practices, and pastoral care.

Judaism, Christianity, Islam

In Judaism, themes of covenant, exile, and return inform understandings of suffering as punishment, test, or occasion for lament and protest. Texts like Job and Lamentations underwrite liturgies of mourning and questioning.

Christian traditions engage suffering in light of the cross and resurrection:

  • Some theologies emphasize participation in Christ’s suffering and the redemptive potential of trials.
  • Others stress God’s solidarity with victims through a suffering or crucified God.

Pastoral responses may include sacramental rites, prayer for healing, and communal support, while debates continue over the appropriateness of offering explicit theodicies to those in acute distress.

In Islam, suffering is often framed as a test (ibtilā’) or as an occasion for patience (ṣabr) and trust (tawakkul). The Qur’an affirms both divine justice and mercy, and pastoral practice emphasizes remembrance of God, charity, and communal responsibility.

Eastern Traditions

In Hinduism, karma and rebirth provide a framework in which present suffering may result from actions in past lives, embedded in a broader cosmic moral order. Some strands focus on liberation (mokṣa) from the cycle of suffering rather than on theodicy in a Western sense.

Buddhism centers the Four Noble Truths, treating suffering (dukkha) as a fundamental feature of existence rooted in craving and ignorance. The focus is on diagnosis and path to cessation, rather than on reconciling suffering with a creator deity.

Pastoral and Practical Concerns

Across traditions, pastoral approaches often differ from philosophical theodicies:

FocusCharacteristics
Companionship and presenceEmphasis on being with sufferers rather than explaining their pain.
Ritual and narrativeUse of prayer, lament, storytelling, and communal rites to situate suffering within a larger spiritual story.
Caution about explanationMany practitioners warn against quick attributions of divine purpose in the midst of acute trauma.

These responses illustrate how lived religious practice may prioritize comfort, solidarity, and ethical responsibility over theoretical resolution of the problem of evil.

15. Political Evil, Structural Injustice, and Collective Responsibility

The problem of evil extends beyond individual wrongdoing to political and structural forms of harm, raising questions about collective agency, responsibility, and the theological interpretation of large-scale injustice.

Political and Structural Evil

Political evil refers to atrocities and injustices perpetrated or enabled by states and institutions:

  • Genocide, war crimes, authoritarian repression.
  • Systemic racism, colonial exploitation, and entrenched economic inequality.

Philosophers and theologians increasingly connect such phenomena to the problem of evil by emphasizing structural injustice: harm embedded not just in individual choices but in laws, norms, and social systems.

Collective Responsibility

Debates arise over:

  • How responsibility is distributed among leaders, participants, and bystanders.
  • Whether collectives (nations, corporations) can be said to bear guilt beyond the sum of individuals.
  • How this bears on traditional notions of sin, repentance, and forgiveness.

Some Christian and Jewish thinkers, for example, frame national or communal atonement in response to historical atrocities, while secular theorists explore legal and moral mechanisms for addressing collective wrongs.

Theodicy and Political Atrocity

Large-scale evils such as the Holocaust, ethnic cleansing, and slavery pose acute challenges to theodicy:

Response typeOrientation to political evil
Traditional theodiciesSometimes apply free will, soul-making, or punishment motifs to mass atrocities, though critics find this morally troubling.
Liberation theologiesFocus on God’s preferential option for the oppressed and call for active resistance against unjust structures, reframing the problem around divine solidarity and human responsibility.
Anti-theodic approachesResist treating political horrors as part of a divine plan, emphasizing remembrance, protest, and solidarity with victims.

Transitional justice mechanisms—truth commissions, reparations, trials—intersect with religious and philosophical debates about whether and how evil regimes can be confronted, forgiven, or transformed. These discussions broaden the problem of evil from a metaphysical puzzle about God and suffering to include the ethical and political tasks of confronting systemic wrongdoing.

16. Contemporary Debates and Future Directions

Contemporary philosophy of religion continues to refine and diversify approaches to the problem of evil, often integrating insights from other disciplines and global perspectives.

Ongoing Debates

Current discussions engage, among others:

  • Fine-tuning and evil: whether the same universe that appears finely tuned for life but rife with suffering supports or undermines theism.
  • Non-classical theisms: process theism, open theism, and other models that modify divine attributes (e.g., limiting omnipotence or foreknowledge) to respond to evil.
  • Horrendous evils and redemption: work by figures like Marilyn McCord Adams and Eleonore Stump on whether and how individual lives marked by extreme suffering can be given meaning in relation to God.

There is also sustained evaluation of skeptical theism’s epistemic costs, the moral adequacy of various theodicies, and the comparative strength of atheistic and theistic explanations of evil.

Expanding Perspectives

Newer directions include:

AreaEmerging questions
Global and postcolonial thoughtHow colonialism, racism, and global inequality reshape understandings of evil and divine justice.
Feminist and gender-focused analysesHow gendered violence and patriarchal structures inform critiques of traditional theodicies.
Environmental ethicsHow climate change, species extinction, and ecological degradation fit into theodical and anti-theodical frameworks.

Engagement with non-Western religious and philosophical traditions also broadens the conceptual resources for addressing suffering and injustice.

Future Trajectories

Scholars anticipate further work on:

  • Integrating empirical research (e.g., trauma studies, psychology of religion) with normative and metaphysical analysis.
  • Developing models of lament, protest, and hope that acknowledge unresolved theoretical tensions.
  • Comparative “worldview” assessments weighing the overall explanatory power of theism, naturalism, and alternative metaphysical pictures in light of evil.

The field thus moves not toward consensus but toward increasingly nuanced and interdisciplinary exploration.

17. Legacy and Historical Significance

The problem of evil has exerted a profound influence on both religious thought and secular philosophy, shaping conceptions of God, morality, and human existence.

Shaping Theology and Philosophy

Historically, efforts to respond to evil have:

  • Helped articulate key divine attributes (omnipotence, omniscience, omnibenevolence) and refine doctrines of providence, freedom, and sin.
  • Stimulated developments in metaphysics (e.g., privation theory, possible worlds), ethics (the nature and gravity of wrongdoing), and epistemology (limits of human understanding).

From Augustine to Leibniz to contemporary analytic philosophy, the drive to explain or resist explanation of evil has been a catalyst for broader theoretical innovation.

Cultural and Intellectual Impact

Beyond academic discourse, the problem of evil has:

  • Informed literature, art, and film, where representations of suffering and protest against God or fate often echo philosophical debates.
  • Influenced public and pastoral responses to disasters, wars, and injustices, shaping how communities narrate and confront collective trauma.
  • Contributed to the rise of modern skepticism and secularization, as some have found traditional religious responses to atrocity inadequate.

Enduring Centrality

Because it touches on universal human experiences of loss, injustice, and moral outrage, the problem of evil remains a recurrent point of reference across eras and cultures. It continues to serve as:

  • A leading argument in critiques of theism.
  • A testing ground for the coherence and plausibility of different theological systems.
  • A bridge between abstract philosophy and concrete ethical and pastoral concerns.

Its legacy is not a settled solution but an ongoing conversation that has shaped, and is likely to continue shaping, how human beings understand the relation between ultimate reality and the darkest aspects of life.

The view that while evil may be logically compatible with God’s existence, the quantity, distribution, and apparent pointlessness of evil make God’s existence improbable.

Theodicy

A systematic attempt to justify God’s permission of evil by explaining how evil contributes to, or is required for, greater goods or morally sufficient reasons.

Defense

A more modest strategy that aims only to show that God and evil are logically compatible, by proposing possible reasons for God’s permitting evil, without claiming they are actual reasons.

Free Will Defense and Free Will Theodicy

The Free Will Defense (Plantinga) argues that it is possible that God could not create significantly free creatures who always freely choose good; free will theodicies claim, further, that God in fact values such freedom enough to permit moral evil.

Gratuitous and Horrendous Evil

Gratuitous evil appears to serve no greater good or necessary purpose; horrendous evil is so severe that it seems capable of destroying a person’s ability to find life meaningful as a whole.

Skeptical Theism

The position that human cognitive limitations prevent us from justifiably concluding that God lacks morally sufficient reasons for permitting the evils we observe.

Discussion Questions
Q1

In what ways does the classic Epicurean-style formulation (as reported by Hume) capture the core tension of the problem of evil, and what important nuances or qualifications does the contemporary literature add?

Q2

How does Plantinga’s Free Will Defense aim to refute the logical problem of evil, and what are its main limitations when we consider natural evil and horrendous evils?

Q3

Are we justified in inferring from ‘we see no good reason for this suffering’ to ‘there is no good reason for this suffering’? How persuasive is skeptical theism’s challenge to that inference?

Q4

Do soul-making and greater-good theodicies adequately respect victims of horrendous evil, or do they inevitably instrumentalize their suffering?

Q5

How does the problem of evil change when we shift our focus from individual wrongdoing to structural and political evil such as genocide, colonialism, or systemic racism?

Q6

From a comparative explanatory perspective, does the distribution of natural and moral evils in our world seem more probable on theism (with theodicies/defenses) or on naturalism?

Q7

What roles do lament, protest, and divine suffering play in religious responses to evil, and how do they relate to (or conflict with) philosophical theodicy?
