The Intellectual Case Against Belief — Stated Honestly

Why It Matters

Just as it is intellectually dishonest to present the case for theism as obviously correct, it is intellectually dishonest to present the case against theism as obviously correct. Both positions have serious arguments and serious difficulties. The intellectual life requires engaging both.

Many students from religious backgrounds have never encountered the strongest arguments against their faith — not because those arguments don't exist, but because their communities have not presented them. This is a form of epistemic protection that tends to produce fragile rather than durable faith. The faith that has never met the problem of evil in its strongest form is not well-equipped for adulthood.

Many students from secular backgrounds have never encountered the strongest arguments against their default skepticism — not because those arguments don't exist, but because their communities have assumed skepticism is the obviously correct position. This is equally a form of epistemic protection.

This lesson exists to give every student the experience of encountering the strongest version of the case they have not yet fully faced. That encounter is uncomfortable and productive, and it is what intellectual adulthood requires.

A Story

The Problem Epicurus Posed

Around 300 BCE, a Greek philosopher named Epicurus posed what would become the most persistent challenge to monotheism in the history of philosophy. He posed it as a puzzle:

'Is God willing to prevent evil, but not able? Then he is not omnipotent. Is he able, but not willing? Then he is malevolent. Is he both able and willing? Then where does evil come from? Is he neither able nor willing? Then why call him God?'

Epicurus was not a bitter man writing in rage. He was a careful philosopher making a logical point: the attributes traditionally assigned to God — all-knowing, all-powerful, perfectly good — seem to be incompatible with the world as we actually find it. Not incompatible in a trivial way that faith can wave off. Incompatible in a way that requires a serious answer.

For two thousand years, philosophers and theologians have been providing serious answers. The free will defense: God permits evil because genuine freedom requires the possibility of choosing evil, and a world with genuine freedom is better than a world of programmed goodness. The soul-making argument: suffering produces virtues — courage, compassion, endurance — that could not exist without it, and those virtues are a higher good than painless comfort. The greater goods defense: God may permit specific evils because they are part of a larger pattern of goods that finite human beings cannot see.

These responses are serious. And yet — as the philosopher William Rowe pointed out in the twentieth century — there seem to be cases where the suffering is so extreme, so pointless, so devoid of any discernible connection to greater goods or soul-making, that the standard responses feel inadequate. A fawn dying slowly in a forest fire, unobserved by any human being, causing no free will choices, producing no soul-making virtues in any person, seems to be simply pointless suffering. If God is both able and willing to prevent pointless suffering, why does it exist?

Emma, who died at fifteen in the opening lesson, was not a philosophical example. She was a real person. The problem of evil has a face. And its face is not an argument to be refuted — it is a question to be sat with, honestly, without flinching.

Vocabulary

Problem of evil (logical form)

The argument that the existence of an all-powerful, all-knowing, perfectly good God is logically incompatible with the existence of any evil or suffering. If such a God existed, no evil would exist. Evil exists. Therefore such a God does not exist. Most philosophers now consider this form of the argument defeated by the free will defense.

Problem of evil (evidential form)

The more powerful contemporary form: while it may be logically possible for God and evil to coexist, the quantity, distribution, and apparent pointlessness of much suffering makes theism significantly less probable. Associated with philosopher William Rowe, who focused on cases of apparently 'gratuitous' evil — suffering with no discernible greater purpose.

Divine hiddenness argument

The argument developed by philosopher J.L. Schellenberg: if a perfectly loving God existed, every person who was open to a relationship with God would be able to have one. But many sincere, open-hearted people find no experience of God at all. Therefore either God lacks perfect love, or God does not exist. The argument targets not just God's existence but God's character.

Argument from religious diversity

The observation that sincere, intelligent people across cultures arrive at dramatically different and mutually exclusive religious beliefs — that the God they worship, the practices they follow, and the revelations they accept vary enormously. If there were a God who wanted to be known, why the confusion? The argument suggests that religious belief may reflect cultural formation rather than genuine divine communication.

Gratuitous evil

Suffering that appears to serve no greater purpose — that is not connected to free will choices, soul-making, or any discernible good. The existence of apparently gratuitous evil is the core of William Rowe's evidential argument. The theist must argue either that no evil is truly gratuitous, or that God has reasons we cannot see.

Guided Teaching

Open by naming what this lesson is doing clearly: it is presenting the strongest arguments against theism, honestly and without strawmanning. The same standard of honest engagement that was applied to the arguments for belief applies here. The goal is not to produce unbelief but to equip students to engage the hardest challenges to faith honestly.

The problem of evil exists in two forms, and students should understand both. The logical form — that an all-powerful, all-knowing, perfectly good God is logically incompatible with any evil — is generally considered defeated by the free will defense, and most contemporary atheist philosophers acknowledge this. The evidential form is more difficult: the sheer quantity and apparent pointlessness of much suffering makes theism less probable, even if not logically impossible. This distinction matters. The logical form of the argument is not the strongest form.

William Rowe's case of the fawn is worth dwelling on. Not because it is unanswerable — theists have responses — but because it captures something that the theoretical versions of the problem miss: the intuition that some suffering simply seems pointless. Any serious theistic response has to account for this intuition honestly, not wave it away. Students who are believers should sit with the intuition before reaching for their responses. Students who are skeptics should engage the theistic responses rather than assuming they are mere rationalizations.

The hiddenness argument is less frequently encountered but philosophically powerful. J.L. Schellenberg's version focuses on non-resistant non-belief: the fact that sincere, open-hearted seekers sometimes find nothing. The theistic responses include: God has reasons for hiddenness (soul-making, the value of seeking), the absence of felt experience does not mean absence of God, and the 'openness' of the seeker may be more complicated than it appears. Students should engage these responses seriously rather than assuming one side wins easily.

The argument from religious diversity is often underestimated because it is often stated crudely. The sophisticated version is not 'there are many religions, therefore none is true' — that is a non-sequitur. The sophisticated version is: if a personal God wanted to be known and had intervened in history to make himself known, we would expect more convergence in human religious experience than we observe. The fact that sincere seekers arrive at wildly different conclusions is evidence (not proof) that the variations reflect cultural formation rather than genuine revelation. The theistic response: revelation is real but human reception of it is fallible and culturally shaped. This is a genuine back-and-forth.

Close by naming what honest intellectual engagement with these arguments requires of students on both sides. For believers: you must not retreat to 'God's ways are mysterious' as a first move — that is not engagement, it is avoidance. The serious theist has actual responses to these arguments, and those responses deserve to be made. For skeptics: you must not treat these arguments as knock-down proofs that settle the question — they are powerful probabilistic arguments that shift the balance, but the theistic responses have not been silenced. The question remains open. Both conclusions — that God exists and that God does not exist — require intellectual courage to hold honestly.

For Discussion

1. 1.What is the difference between the logical and evidential forms of the problem of evil? Why does the distinction matter?
2. 2.Epicurus posed his puzzle around 300 BCE. What does it mean that philosophers are still debating it in 2026? Does the persistence of the debate suggest the question is unanswerable, or that it is genuinely difficult?
3. 3.How would you respond to Rowe's case of the fawn? What is the most honest theistic response you can construct? Does it satisfy you?
4. 4.Schellenberg's hiddenness argument focuses on 'non-resistant non-belief' — sincere seekers who find nothing. Have you encountered people like that? What do you think explains their experience?
5. 5.The argument from religious diversity notes that sincere seekers arrive at different conclusions. Is that evidence against any of them being right, or is it compatible with one of them being correct? How would you reason about that?
6. 6.After this lesson and the previous one, where do you stand — not on whether God exists, but on whether the question is genuinely open? Has your sense of how open the question is changed?

Practice

Steel-Manning the Case Against Belief

1. 1.Choose one of the three arguments from this lesson: the problem of evil, the hiddenness argument, or the argument from religious diversity.
2. 2.Write a two-paragraph version of that argument in your own words — as compellingly as you can. Do not strawman it.
3. 3.Write one paragraph presenting the strongest theistic response to the argument.
4. 4.Write one final paragraph: how would a defender of the argument reply to that response? What does the back-and-forth reveal about the difficulty of the question?
5. 5.Compare your work with what you wrote in the previous lesson's exercise. Which argument — for or against — did you find it harder to state strongly? What does that reveal about your own prior assumptions?
