The Problem of Suffering

Suffering, not just evil

Philosophers usually frame the challenge as the problem of evil: if God is all-powerful, all-knowing, and perfectly good, why does evil exist? The word “evil” tends to pull the conversation toward moral failure — murders, genocides, cruelty — things that a defender of God can blame on human free will. But that framing quietly skips past the harder case. A child dying of leukaemia has not been wronged by anyone with free will. A fawn burned alive in a forest fire has not been wronged by a sinner. The deepest version of the problem is not about human wickedness. It is about suffering.

The philosopher William Rowe put it starkly in 1979: consider a fawn trapped in a forest fire, lying for days with terrible burns before finally dying. No one saw it. No moral lesson was drawn. No soul was purified. There appears to be no good that this suffering served. If cases like this — and there are countless such cases, every day — are what they seem to be, then the God of classical theism is harder to square with the world than theology usually admits.

Natural evil and moral evil

Theologians distinguish between moral evil (cruelty performed by free agents) and natural evil(suffering caused by the world itself — disease, earthquakes, tsunamis, predation, birth defects). Most free-will defences address moral evil only. They argue that God permits human wickedness because the good of genuine moral freedom outweighs its misuse. Whatever one thinks of that argument, it does nothing for natural evil.

Earthquakes do not have free will. Cancer cells do not have free will. Parasitic wasps that lay their eggs inside living caterpillars do not have free will. The 2004 Indian Ocean tsunami killed roughly 230,000 people, including tens of thousands of children. No human chose that. It was the plate tectonics of a planet that supposedly bears the fingerprints of a loving designer. If God designed the geology, God designed the geology that kills children.

Animal suffering and Darwin’s wasp

Charles Darwin lost his faith partly over this. In an 1860 letter to the American botanist Asa Gray, he wrote: “I cannot persuade myself that a beneficent and omnipotent God would have designedly created the Ichneumonidae with the express intention of their feeding within the living bodies of Caterpillars.” The ichneumon wasp lays its eggs inside caterpillars; the larvae eat their host alive from within, carefully avoiding vital organs so the meal stays fresh. Millions of such arrangements run, right now, across every ecosystem on Earth.

Richard Dawkinshas returned to this point repeatedly. Across roughly 500 million years of animal nervous systems, the sheer volume of agony — animals eaten alive, animals starving, animals dying of parasite load, animals watching their young killed — dwarfs anything humans have inflicted on each other. This is not a side issue. It is what evolution actually looks like: a vast, uncurated engine of pain. Theodicies that centre on human souls have nothing plausible to say about any of it.

Childhood cancer and Stephen Fry’s answer

In 2015, Irish broadcaster Gay Byrne asked Stephen Frywhat he would say if he met God at the pearly gates. Fry’s reply became the most watched moment of that year’s Irish television: “I’d say, bone cancer in children? What’s that about? How dare you? How dare you create a world in which there is such misery that is not our fault? It’s not right.”

Fry was not making a formal philosophical argument. He was articulating what is sometimes called the emotional or existentialproblem of suffering — the version of the problem that most people actually feel before they are taught to feel otherwise. A toddler dying of a brain tumour cannot be explained by Adam’s sin, by the fall, by human free will, or by the toddler’s need to build character. A defence that relies on hidden goods the sufferer cannot access is a defence that has stopped describing the God people actually pray to.

Logical vs. evidential

Contemporary philosophy of religion distinguishes two versions of the challenge. The logicalproblem of evil claims that the existence of any evil is strictly incompatible with an omnipotent, omniscient, perfectly good God. After Alvin Plantinga’s free-will defence, most philosophers — including most atheist philosophers — grant that the logical version is not decisive on its own: it is at least possible that God has a reason we cannot see.

The evidential problem of suffering is tougher. It does not claim strict incompatibility. It claims that the amount, distribution, and pointlessnessof actual suffering — the fawn, the tumour, the tsunami, the 500 million years of animal pain — is strong evidence against the classical God. “God might have a reason” is not a reason; it is a placeholder. And a God whose goodness is entirely compatible with bone cancer in a three-year-old is a God whose goodness has been stretched until it means nothing familiar.

Why theodicy fails emotionally even when it’s logically sound

A theodicy is an attempt to justify God’s permission of suffering — soul-making (Hick), greater-good (Swinburne), skeptical theism (“God’s reasons are beyond us”), free-will defence (Plantinga). Some are sophisticated. Most can be made logically consistent. None of them sound right in a paediatric oncology ward. That mismatch is not a trivial complaint. If the argument that God is good requires you to describe a child’s last six months as a hidden blessing, the argument has lost contact with what “good” ordinarily means.

This is why the problem of suffering is closely linked to the problem of hell, divine hiddenness, and the wider question of whether God exists. Each sharpens the same point: the God described in the texts looks nothing like the universe we actually inhabit. A disciplined atheism does not claim to have proven God impossible. It claims that, when you stop averting your eyes from what suffering is actually like, the probability falls. For many people, the first honest crack in a lifelong faith appears not in a logic textbook but in an intensive care unit.
