What this dot point is asking
You need to explain the design (teleological) argument for God, from Aquinas's fifth way and William Paley's watchmaker analogy, including the arguments from order and purpose, and then evaluate the major challenges from David Hume, Charles Darwin and the problem of evil, noting the anthropic principle as a modern restatement. This is one of the classical arguments for God's existence that AS 8 requires you to explain and assess.
Aquinas's fifth way
The argument is a posteriori (based on observation of the world) and inductive (its conclusion is probable, not certain), which distinguishes it from the a priori ontological argument.
Paley's watchmaker analogy
Hume's criticisms
David Hume's Dialogues Concerning Natural Religion (published 1779) anticipated and attacked the argument.
- The analogy is weak. The universe is not much like a machine; it resembles a growing organism (a vegetable) at least as well, which would suggest no designer.
- The universe is unique. We have no experience of other universes being made, so we cannot reason from one case to a designer.
- Order can arise by chance. Given infinite time, particles may fall by chance into a stable, ordered arrangement (the Epicurean hypothesis), with no designer needed.
- The designer need not be God. Even if there is a designer, the argument cannot show it is single, infinite, perfect or the God of theism; an imperfect world might suggest an imperfect or apprentice designer.
Darwin, evil and the anthropic principle
The problem of evil adds that the natural world contains waste, suffering and apparent cruelty (predation, disease, natural disasters), which counts against a wholly good and competent designer.
Strengths and weaknesses
A model evaluation paragraph might run: "The design argument has real intuitive force: the order and apparent purpose of the world, from the eye to the fine-tuned constants of physics, genuinely cry out for explanation, and the anthropic principle gives the argument a contemporary, scientific form that Darwin does not touch, since evolution presupposes rather than explains the law-governed universe in which it operates. Yet the criticisms are serious. Hume showed the analogy between the universe and a machine is weak and that order might arise by chance; Darwin removed the need for a designer to explain biological complexity; and the waste and suffering in nature count against a perfect designer. The judgement, therefore, is that the design argument fails as a proof, but that its modern fine-tuning version remains a suggestive, if inconclusive, pointer towards a designer rather than a knock-down demonstration."
Try this
Q1. What does a posteriori mean, and why is the design argument a posteriori? [2 marks]
- Cue. A posteriori means based on experience; the design argument starts from observed order and purpose in the world.
Q2. Explain Paley's watchmaker analogy. [6 marks]
- Cue. A found watch with purposeful parts implies a watchmaker; by analogy the far greater contrivance of nature, such as the eye, implies a divine designer, even if imperfect.
Q3. "Hume's criticisms destroy the design argument." Discuss. [12 marks]
- Cue. Weigh Hume's points (weak analogy, unique universe, chance, imperfect designer) against the reply that fine-tuning gives the argument a form Hume did not anticipate. Reach a judgement.

CCEA AS 8 201812 marksExplain Paley's version of the design argument.Show worked answer →
An AO1 question, so reward accurate exposition of Paley's analogy and its
structure.
The analogy. Explain that Paley imagines finding a watch on a heath: its
intricate parts working together for a purpose force the conclusion that it
was designed, unlike a stone. By analogy, the order and purpose of the
natural world point to a divine designer.
Design qua purpose and regularity. A strong answer distinguishes design qua
purpose (parts arranged for an end, like the eye) from design qua
regularity (the ordered motion of the planets), both of which Paley uses.
The conclusion. The argument is a posteriori and inductive, moving from
observed features of the world to the probable existence of God as designer.
Accurate detail reaches the top band.
CCEA AS 8 202112 marksComment on the view that Darwin's theory of evolution destroys the design argument.Show worked answer →
An AO2 evaluation question, so argue both sides and judge.
Supporting the claim. Natural selection explains the apparent design of
living things by unguided, gradual adaptation, removing the need for a
designer to account for the eye or other complex organs.
Challenging the claim. Evolution explains biological complexity but not why
there is an ordered, law-governed universe at all; the anthropic principle
and fine-tuning relocate design to the laws and constants that make
evolution possible.
A judgement that Darwin undermines Paley's biological version but not the
wider argument from cosmic order reaches the higher bands.
