Key Idea: Topic 5.1 asks the oldest question in the philosophy of religion: is there a God, and can reason alone tell us? You test the famous arguments FOR God, the strongest challenges AGAINST, and then judge whether the debate can be settled by argument at all. This is the core of the optional theme, and it feeds Paper 1 Section B — a 25-mark 'Evaluate the claim that…' essay.
🧠 The four big questions, one card each
Topic 5.1 at a glance
- 5.1.1 · What do we mean by 'God'? — Before you argue, define the target. The classic 'omni' God is all-powerful, all-knowing and all-good. Different traditions mean different things — pin down WHICH God a claim is about, or the whole argument slips.
- 5.1.2 · Arguments FOR God — Three families: ontological (God exists by definition), cosmological (everything needs a first cause), teleological (order needs a designer). Each moves from an everyday fact to a divine conclusion — the question is whether the leap holds.
- 5.1.3 · Arguments AGAINST God — The problem of evil is the strongest: if God is all-good and all-powerful, why real suffering? Add the omnipotence paradox and the fact that religions disagree. These target the 'omni' God directly.
- 5.1.4 · Can reason settle it? — The arguments fight to a draw — none forces assent. So people reach God three ways: reason, faith, or experience. A mature answer says WHICH route can decide, and why.
A priori arguments work from concepts alone, before experience (the ontological argument: unpack the idea of God and existence falls out). A posteriori arguments work from what we observe in the world (cosmological and teleological: start from causes or order, then infer a cause of it all). Knowing which kind you're facing tells you exactly where to push — a definition, or the evidence.
✍️ Bring it together — a Section B essay
Evaluate the claim that the existence of evil makes belief in an all-good, all-powerful God unreasonable.

Important: Preaching or debunking instead of evaluating. Section B is not a chance to defend or attack religion — it's a balanced weighing. Give the STRONGEST version of each side, treat believer and non-believer arguments with equal seriousness, then reach a reasoned conclusion. A one-sided essay caps your marks however fluent it is.
✅ Check yourself
If you can answer these six, you have the spine of the whole topic.
What is the 'omni' God? The classic God of the arguments: omnipotent (all-powerful), omniscient (all-knowing) and omnibenevolent (all-good). Most arguments target THIS definition.
A priori vs a posteriori argument? A priori works from concepts before experience (ontological); a posteriori works from what we observe (cosmological, teleological).
The cosmological argument in one line? Everything that exists has a cause; there can't be an endless chain, so there must be a first, uncaused cause — which we call God.
The problem of evil? An all-good, all-powerful God would prevent pointless suffering, yet it exists — so either God lacks a power, or doesn't exist. The strongest argument against.
What is a theodicy? A believer's reply to the problem of evil that gives evil a purpose — e.g. free-will defence, or Hick's soul-making.
Can reason settle God's existence? The arguments fight to a draw — none forces assent. People then reach God by reason, faith or experience; a strong answer says which route can decide.
Exam tips
- Section B is a 25-mark 'Evaluate the claim…' essay with NO stimulus — the existence of God is the richest claim to reach for, and this whole topic feeds it.
- Define the God in question first — most arguments only work against the 'omni' God, so name that target.
- Name a thinker ONLY with their argument (Anselm's definition, Paley's watch, Hick's soul-making) — a name alone earns nothing.
- Weigh both sides evenly and end on a reasoned conclusion — never 'it's just a matter of faith'.
