The Design Argument

One unit, one ladder — climbed by Paley, attacked by Hume, audited for proof. Does the order of nature point to a designing God?

The
big
question

Does the appearance of design in nature prove — or even make probable — the existence of God?

01

The inference ladder

The whole unit lines up on one axis. Paley climbs from observation to God; Hume attacks each rung; the verdict asks what is left. Pick a lesson, then tap a position to see what it claims and where it's strong or weak.

Tap a circle — or use Tab and Enter — to explore each position.

The thread that ties it together

Top answers don't treat the three debates separately. Two ideas run through all of them — spot the thread and you're writing at the top of the mark scheme.

The inference ladder

Observation → purpose → designer → God. Every claim in the unit lives on a rung — and the evidence thins as you climb.

Probable vs proved

Paley's own method caps the argument at probability. Half the exam questions turn on what 'prove' is allowed to mean.

The Paley–Hume dialectic

Hume died before Paley published, yet every rung has a Humean attack and a Paleyan reply. Stage the dialogue and you're at the top of the mark scheme.

02

One argument, three lessons

The unit splits into three lessons. They look different, but each is really asking how far up the ladder the evidence reaches.

Lesson 1

Paley's Argument

Does order imply a designer?
The basisA posteriori & inductive — probable, never certain.
The watchParts framed for a purpose → an artificer.
The analogyWatch : watchmaker :: universe : God.
The defenceBroken watch · unknown parts · 'order' · ignorance.
Lesson 2

Hume's Criticisms

How deep does each cut?
Lesser designerProportion belief to the evidence.
EvilThe inconsistent triad — a limited designer.
VegetableThe world grows — it isn't a machine.
Anthropomorphism & chanceGod in our image · order by chance.
Lesson 3

Proof, Reason & Faith

What is it worth?
StrengthsShared evidence; an everyday inference.
WeaknessesHume's stack; the induction ceiling.
Proof?Not by any strict standard — probability at best.
FaithSupport & respectability — or nothing to lean on.

How to revise this unit

Use your resources in this order. The Philosopher Companion is where you learn to plan both question types.

Watch the lesson & listen to the podcast

One podcast per lesson — a teacher and student talk each position through to a judgement. Annotate as you listen.

Complete the greyscale booklet

Read the given text, write the key claims in your own words, then decide the strength and weakness you'd give each position.

Match & apply the key terms

In the Companion: match each term to its meaning, then use it in a sentence. RAG-rate the mastery checklist with the three faces.

Plan AO1, then build AO2 on top

Use the Companion frameworks and the guidance-left / your-turn-right scaffolds. Never evaluate what you haven't first explained.

AO1 · Examine the views (10)
What it is — the factual chain: define the argument's character (a posteriori, inductive), then set out each step or criticism in order and apply the evidence (the watch, the eye, the orbits).
Aim — explain the whole chain accurately and neutrally. No judging yet.
AO2 · Evaluate the claim (15)
What it is — a three-paragraph dialectic: position, then evaluation → counter-evaluation → implication; mirror it; then judge.
Aim — weigh Paley against Hume rung by rung, fix what 'prove' must mean, and reach a justified judgement that links back to your thesis.

Watch: the whole unit in one go

A full review of the Design Argument — Paley's ladder, Hume's criticisms, and the verdict on proof, reason and faith. Best watched before you start revising, then again to check your recall.
