The Philosophical Pressure

The problem of evil asks how belief in God can be reconciled with the existence of evil and suffering. In this Component 1 philosophy topic, the pressure normally falls on a God understood as:

• omnipotent: all-powerful, so able to prevent evil;
• omniscient: all-knowing, so aware of evil and of possible ways to prevent it;
• omnibenevolent: wholly good or perfectly loving, so opposed to evil and suffering.

The problem does not begin from a minor inconvenience. It begins from suffering that seems serious enough to challenge the moral character, knowledge or power of God: cruelty, disease, disaster, grief, oppression, pain and apparently innocent suffering. The previous specification point distinguishes natural evil and moral evil; in this lesson those categories are useful examples, but the focus is the form of the argument.

The same pressure can be shaped in two different ways:

The Logical Problem

The logical form aims to show that theism contains an internal contradiction. It is often explained through an inconsistent triad:

The logical argument then runs like this:

1. If God is all-powerful, God can prevent evil.
2. If God is all-knowing, God knows about evil and knows how to prevent it.
3. If God is wholly good, God would want to prevent evil.
4. Evil exists.
5. Therefore, a God who is all-powerful, all-knowing and wholly good does not exist.

J.L. Mackie is a useful reference point for this kind of argument because he presented the problem as an inconsistency within the central claims of theism. AQA's wording for this row does not require Mackie by name, so the safest exam move is to understand the argument first and use the scholar only if it helps your explanation.

The hidden pressure point is the claim that a wholly good God would prevent every evil that God could prevent. If that claim is necessarily true, the contradiction looks powerful. If it is possible that God has a morally sufficient reason for allowing some evil, the contradiction is harder to prove.

The Evidential Problem

The evidential problem is less absolute than the logical problem. It does not need to prove that God and evil are logically incompatible. Instead, it asks whether the world looks like the kind of world we would expect if it were governed by a wholly good, all-knowing and all-powerful God.

An evidential argument may run like this:

1. Some suffering appears pointless or gratuitous.
2. A wholly good, all-knowing and all-powerful God would not allow pointless suffering.
3. Therefore, such suffering is evidence against the existence of that God.
4. So God's existence is less probable, even if not strictly impossible.

William Rowe is a useful reference point for the evidential form because he argued that some intense suffering appears to be preventable without losing a greater good or allowing an equal or worse evil. Again, AQA's exact wording names the evidential problem, not Rowe, so the scholar should support the concept rather than replace it.

The word appears matters. The evidential argument often begins from what human beings can reasonably see: some suffering looks pointless. A theist may reply that humans are not in a position to know all possible divine reasons. The debate then becomes one about evidence, inference and probability, not simple contradiction.

Comparing The Two Forms

Students often blur the two forms together. The table below is the distinction you need to keep clean.

Two careful exam distinctions follow.

First, the logical problem has a very high burden. It must show not merely that evil is puzzling, but that no possible morally sufficient reason could make God and evil consistent.

Second, the evidential problem has a lower but still serious burden. It does not need to prove contradiction; it only needs to argue that the actual pattern of suffering is better evidence against God than for God.

AO1 To AO2 Bridge

Good AO1 identifies the form of the problem accurately. Good AO2 asks what kind of response would actually answer that form.

This bridge prevents a common weak answer: saying "the free will defence solves the problem of evil" without asking which problem it is meant to solve. A defence that shows God and evil are logically compatible may answer the logical problem, but the evidential problem can still ask whether the world contains more suffering than that defence would lead us to expect.

Using The Distinction

In future essays, this lesson is most useful as a precision tool. You can use it to stop a paragraph drifting into a general discussion of suffering.

A basic paragraph might say:

Evil is a problem because God is good and powerful, but bad things happen, so God might not exist.

That is true but too broad. A stronger paragraph names the form:

The logical problem of evil argues that the existence of evil is incompatible with an omnipotent, omniscient and omnibenevolent God. The argument depends on the claim that a wholly good God would prevent every evil that God could prevent. If even one possible morally sufficient reason for allowing evil can be shown, the strict contradiction is weakened; however, this does not automatically answer the evidential problem, which asks whether the actual scale and apparent pointlessness of suffering still makes God's existence unlikely.

Why this improves the answer:

• it identifies the precise form of the problem;
• it uses the divine attributes accurately;
• it explains the assumption under pressure;
• it turns AO1 into AO2 by judging what kind of reply would be enough.

Synoptic link. This point links back to the concepts of natural and moral evil and forwards to AQA's separate response lessons: theodicy framework, Hick's soul-making theodicy, the free will defence, process theodicy as presented by Griffin, and strengths and weaknesses of each response. For later essay-bank work, it belongs in the C1-evil-and-suffering and C1-philosophy-synoptic clusters.
