Abstract
The problem of evil is one of the most fundamental challenges in the philosophy of religion and has often been described as the strongest argument against classical theism. It arises from the apparent incompatibility between the existence of moral and natural evils and the divine attributes of omnipotence, omniscience, and perfect goodness. In contemporary philosophy of religion, alongside the logical problem of evil, the evidential or probabilistic problem—most notably advanced by William Rowe—has gained particular prominence. In response, the position known as skeptical theism has been developed, emphasizing the cognitive limitations of human beings in grasping God’s reasons and purposes for permitting evil. This paper offers an analytic and critical examination of skeptical theism through the views of three of its leading proponents: Stephen Wykstra, Michael Bergman, and William Alston. It is argued that although skeptical theism aims to block the inference from “we see no justifying reason for evil” to “there is no justifying reason,” it ultimately relies on epistemic humility in a way that fails to provide a persuasive response to non-theistic critics. The paper concludes that skeptical theism does not successfully resolve the problem of moral and natural evil; rather, it leads to a form of agnosticism about divine attributes and purposes, rendering it insufficient as a rational defense of classical theism against the problem of evil. Then considers the free will defense with some reservations and the best possible world theodicy with a reservation as convincing answers to the problem of evil

Introduction
The problem of evil is one of the most fundamental and challenging issues in the philosophy of religion, often described as the strongest argument against classical theism. Its significance and difficulty are such that it has been called "the rock of atheism." The problem arises from the apparent incompatibility between the existence of moral and natural evils in the world and the divine attributes of omnipotence, omniscience, and perfect goodness. In the history of philosophy, Epicurus famously articulated this challenge through a series of questions demonstrating that the existence of evil is incompatible with a God who is both willing and able to prevent it. In the modern period, David Hume revitalized this argument, and in recent decades, atheist philosophers such as William Rowe, Anthony Flew, and J.L. Mackie have prominently advanced the problem, while theist philosophers like Alvin Plantinga and John Hick have sought to provide new responses.
The nature of evil has been understood in various ways throughout history. In traditional theology, evil was sometimes defined as privation or as a relative matter. In contemporary philosophy, however, the discussion focuses on the instances of evil—events or phenomena that cause pain and suffering to human beings. Evil is commonly divided into two categories: moral evil, which results from human free will and includes acts such as murder, torture, and aggression; and natural evil, which arises from the natural world and includes events such as earthquakes, floods, and diseases. The logical problem of evil, as formulated by Mackie, asserts that the existence of a God who is omnipotent, omniscient, and perfectly good is logically incompatible with the existence of evil. In response, Plantinga developed the free will defense, arguing that it is possible that God could not create free creatures who always do what is right, and that the existence of evil is a necessary consequence of human freedom. However, Anthony Flew countered that it is logically possible for God to create free creatures who, by their own free will, always choose the good and never commit evil. In response to the evidential or probabilistic problem of evil, advanced notably by William Rowe, skeptical theism has emerged as a significant position. Skeptical theism emphasizes the cognitive limitations of human beings in understanding God's reasons and purposes for permitting evil. This paper examines and evaluates the views of three prominent representatives of skeptical theism—Stephen Wykstra, Michael Bergman, and William Alston—and argues that while skeptical theism attempts to block the inference from "we see no justifying reason for evil" to "there is no justifying reason," it ultimately fails to provide a persuasive response to non-theistic critics. The paper concludes that skeptical theism leads to a form of agnosticism about divine attributes and purposes rather than resolving the problem of moral and natural evil, rendering it insufficient as a rational defense of classical theism.

Research Methodology
This research employs an analytical-critical approach to examine and evaluate the arguments of skeptical theism as presented by three of its leading proponents: Stephen Wykstra, Michael Bergman, and William Alston. The study involves a systematic review and analysis of primary texts, including Wykstra's articulation of the CORNEA principle, Bergman's formulation of skeptical theses (ST1-ST3), and Alston's critique of Rowe's evidential argument from evil. The analysis proceeds through several stages: first, a detailed exposition of each thinker's position; second, an evaluation of the logical and epistemological foundations of their arguments; third, a critical assessment of the strengths and weaknesses of their approaches; and fourth, a comparative analysis of the three perspectives to identify common themes and divergent responses. The methodology also involves examining the broader implications of skeptical theism for classical theism, particularly concerning the possibility of knowledge of divine attributes and purposes. The research draws upon key philosophical debates in contemporary philosophy of religion, including discussions of the logical and evidential problems of evil, the nature of divine omnipotence and omniscience, and the limits of human cognitive faculties.

Discussion
Skeptical Theism and Its Rationale
Skeptical theism emerged as a response to the evidential problem of evil, particularly as formulated by William Rowe. Rowe argued that there are instances of intense suffering—such as a fawn burning in a forest fire or an innocent girl being raped and murdered—that an omnipotent, omniscient being could have prevented without losing any greater good or permitting any equal or worse evil. From this, he concluded that such evils are gratuitous and that their existence constitutes evidence against the existence of God. Skeptical theists respond by emphasizing the cognitive limitations of human beings. They argue that our inability to perceive any justifying reason for allowing a particular evil does not entail that no such reason exists. Given the vastness of the divine intellect and the limitations of human understanding, it is entirely possible that God has reasons for permitting evils that we cannot comprehend.
Stephen Wykstra introduced the CORNEA principle (Condition of Reasonable Epistemic Access) to formalize this response. According to CORNEA, if it appears to a person S that something is the case, then it is reasonable for S to believe it, unless there is evidence to the contrary. However, Wykstra argues that in the case of evil, we do not have the relevant epistemic access to determine whether the apparent absence of a justifying reason is genuine or merely a result of our cognitive limitations. He illustrates this with examples: if you look into a large warehouse full of debris and do not see a table, you cannot conclude that there is no table; or if you have a cold and cannot smell whether milk has gone sour, you cannot conclude that the milk is not sour. The key point is that our cognitive faculties may be insufficient to detect the goods that justify the permission of evil. Michael Bergman further develops this skeptical position by formulating three skeptical theses: we have no good reason to think that the goods we can conceive are representative of the goods that exist; we have no good reason to think that the evils we can conceive are representative of the evils that exist; and we have no good reason to think that the necessary relations between goods and evils we can conceive are representative of the actual relations. He argues that Rowe's argument fails because it assumes that the goods and evils we can conceive of are representative of the entire range of possible goods and evils—an assumption that is unjustified given our cognitive limitations. William Alston, while not explicitly identifying as a skeptical theist, argues that human cognitive limitations prevent us from adequately assessing Rowe's claim that some evils are gratuitous. He identifies several factors that contribute to these limitations: our ignorance of relevant facts; the complexity of the world; the difficulty of determining what is metaphysically possible or necessary; our ignorance of probabilities; and the limitations of our ability to judge values.
Critical Evaluation of Skeptical Theism
Despite its initial appeal, skeptical theism faces several significant challenges. The most fundamental criticism is that it seems to lead to a form of theological agnosticism. If our cognitive faculties are so limited that we cannot discern God's reasons for permitting evil, then it is unclear how we can have any positive knowledge of God's attributes or purposes. Skeptical theism appears to undermine not only our ability to understand why evil exists but also our ability to understand God's goodness, wisdom, and justice. This is a serious problem because classical theism requires that we have some knowledge of God's attributes; if we cannot know that God is good or wise, then the very concept of God becomes empty. As we have argued, if we accept the skeptical theist's conclusion that we cannot know God's purposes, then we must also accept that we cannot know God's goodness, wisdom, or justice. This is essentially a form of negative theology, which may be acceptable for some religious traditions but is problematic for classical theism, which asserts positive knowledge of God's attributes.
Another major criticism is that skeptical theism fails to provide a satisfying response to the non-theistic critic. The problem of evil is a challenge raised by atheists, and the burden of proof is on the theist to show that the existence of evil is compatible with the existence of a perfectly good, omnipotent, and omniscient God. Skeptical theism, however, merely states that we cannot know why God permits evil. This is not an argument that persuades the atheist; it is an argument that may convince someone who already believes in God. An atheist will not be persuaded by the claim that God has reasons we cannot understand, because the atheist does not believe that God exists in the first place. As we have argued, the skeptical theist's response is at best a way of preserving the coherence of theism for the believer, not a way of addressing the atheist's challenge.
A third criticism concerns the problem of unnecessary evil. Even if we grant that we cannot fully understand God's reasons, it is still rational to question whether a particular evil is necessary. If an omnipotent God could achieve a greater good without permitting a particular evil, then there is no reason to permit that evil. Skeptical theism cannot simply assert that God's reasons are beyond our comprehension; it must address the specific examples of apparently gratuitous evil. As we have argued, in many cases, we can conceive of alternatives that seem better than the current state of affairs. For example, we can conceive of a world in which innocent children do not suffer from terrible diseases, or where natural disasters do not cause mass destruction. If these alternatives are logically possible, then why does God not realize them? Skeptical theism does not provide a satisfactory answer to this question.
Furthermore, skeptical theism seems to imply that we cannot make any moral judgments about God's actions. If we cannot understand God's reasons, then we cannot say that God's actions are good or just. This is a serious problem for theodicy, which seeks to defend God's goodness in the face of evil. If we cannot know that God is good, then theodicy becomes impossible. As we have argued, skeptical theism undermines the very possibility of providing a rational defense of God's goodness. It transforms theodicy into a form of fideism, where belief in God's goodness is held despite a lack of rational evidence. This may be acceptable for some believers, but it is not a satisfactory response to the philosophical problem of evil.
Alternative Responses to the Problem of Evil
Given the limitations of skeptical theism, it is necessary to consider alternative responses to the problem of evil. In the case of moral evil, the free will defense remains a viable option, provided that certain conditions are met. First, it must be clarified whether human freedom is absolute or limited. Second, the compatibilist position of Anthony Flew must be addressed. As we have argued, Plantinga's incompatibilist position, which holds that freedom requires the possibility of choosing evil, provides a plausible response. However, the objection that God could have created free creatures who always choose the good must be addressed. The concept of infallibility in Shi'a theology, which holds that certain individuals possess infallibility while still being free, suggests that this possibility is not entirely impossible. The question remains: why did God not create all human beings as infallible? A possible response is that the value of freely choosing the good over evil may be lost in a world where evil is impossible. In such a world, the significance of moral choices would be diminished, and the very concepts of good and evil would be unclear. In the case of natural evil, the idea of the best of all possible worlds offers a potential response. This idea, famously associated with Leibniz, holds that this world is the best possible world, given the constraints of creation. The argument is that the current world, with all its imperfections, is better than any alternative. Theodicies such as the argument from divine perfection and the argument from the perfection of creation can be employed to support this view. As we have argued, the key is to show that the current world, with its specific structure and elements, is not obviously worse than any conceivable alternative. The critic who claims that God could have created a better world must specify what such a world would be like. Without a clear description of a better world, the objection remains vague and unconvincing. The problem of natural evil can be addressed by appealing to the idea of divine wisdom in creating a world that is governed by regular and predictable laws. This allows for the development of human knowledge and agency. The alternative—a world without natural laws—would be chaotic and unpredictable, and it is not clear that such a world would be better.

Conclusion
This paper has examined and evaluated the skeptical theist response to the problem of evil, focusing on the views of Stephen Wykstra, Michael Bergman, and William Alston. Skeptical theism, which emphasizes the cognitive limitations of human beings in understanding God's reasons for permitting evil, offers an initial response to the evidential problem of evil. However, upon closer examination, this approach faces significant challenges. The most serious criticism is that skeptical theism leads to a form of theological agnosticism that undermines our knowledge of God's attributes and purposes. If we cannot understand God's reasons for permitting evil, then we cannot understand God's goodness, wisdom, or justice. This is a problem for classical theism, which requires positive knowledge of God's attributes. Furthermore, skeptical theism fails to provide a persuasive response to non-theistic critics of theism. The problem of evil is raised by atheists, and the burden of proof is on the theist to show that the existence of evil is compatible with the existence of God. Skeptical theism merely asserts that God's reasons are beyond our comprehension, which is unlikely to convince an atheist. Alternative responses to the problem of evil are available and deserve serious consideration. The free will defense offers a plausible response to moral evil, provided that certain conditions are met, including a clear account of the nature of freedom and a response to the objection that God could have created free creatures who always choose the good. The idea of the best of all possible worlds offers a potential response to natural evil, although it requires a convincing demonstration that the current world, with all its flaws, is better than any alternative. In conclusion, skeptical theism, while initially appealing, ultimately fails to provide a satisfactory resolution to the problem of evil. Its emphasis on cognitive humility, while valuable, cannot substitute for a rational defense of God's goodness in the face of moral and natural suffering. The paper has argued that the problem of evil remains a significant philosophical challenge, and that theistic philosophers must continue to develop and refine their responses to this important issue.
