What this key area is asking
The teleological or design argument is the second a posteriori argument: it starts not from the bare existence of the universe but from its apparent order, complexity and purpose, and infers a designer. You must understand Paley's watchmaker analogy and the argument from order and purpose, the modern fine-tuning version, and the two great criticisms, Hume's objections and Darwinian evolution, then evaluate whether the argument survives them.
The argument from order and purpose
The argument is a posteriori and analogical: it reasons from a feature we observe (purposeful arrangement) to the best explanation of it (an intelligent designer). Its strength depends on how strong the analogy is between the order we see and the products of known designers.
Paley's watchmaker
The watch case is meant to make the inference vivid: we do not hesitate to infer a maker for the watch, and Paley claims nature presents even stronger evidence of contrivance. The argument therefore stands or falls on whether natural order really is relevantly like designed artefacts.
The fine-tuning version
The modern fine-tuning version moves the argument from biology to cosmology: the fundamental laws and constants of the universe (the strength of gravity, the cosmological constant) appear improbably suited to the existence of life, such that tiny differences would make life impossible. The best explanation, defenders argue, is a designer who set the parameters. This version is important because it is not touched by evolution: natural selection presupposes the very laws whose fine-tuning is in question.
Criticisms: Hume and evolution
Evolution is the decisive blow to the biological design argument: it removes Paley's strongest examples by showing how apparent design in organisms arises without an intelligence. Hume's objections cut deeper at the analogy itself and at the leap from "a designer" to "the God of theism."
Evaluating the argument
The key evaluative move is to distinguish the versions. Evolution defeats the biological design argument, so an essay that treats Paley as the whole argument concedes too much. But the fine-tuning version survives evolution, because it concerns the laws that make evolution possible; here the debate shifts to whether fine-tuning is best explained by design, by chance, or by a multiverse (many universes, so some are bound to be life-permitting). As with the cosmological argument, even a successful design argument reaches at most a powerful designer, not necessarily the good, personal God of theism. A strong judgement weighs which version, if any, survives its objections.
Worked example
Try this
Q1. What does Paley's watch analogy aim to show? [2 marks]
- Cue. That order arranged for a purpose forces the inference of a designer, and since nature shows the same marks of contrivance, it too must have a designer, namely God.
Q2. Why does evolution not refute the fine-tuning version of the design argument? [2 marks]
- Cue. Fine-tuning concerns the laws and constants of the universe that make life possible, which natural selection presupposes rather than explains.

SQA AH (Philosophy of Religion)20 marksTo what extent does the theory of evolution undermine the teleological argument?Show worked answer →
A strong essay sets out the design argument, explains how evolution challenges it, and judges how far the challenge succeeds.
Explain the argument from order and purpose: the universe and living things show order, complexity and apparent purpose, like a watch whose parts are arranged for an end (Paley); such design implies a designer, namely God. Then set out the Darwinian challenge: evolution by natural selection explains the apparent design of living things without a designer, since random variation and the survival of the fitter produce complex, well-adapted organisms over time, so the watchmaker is blind. Evaluate: this is a powerful answer to the biological version of the argument and removes its strongest examples, but defenders shift to the fine-tuning version, that the laws and constants of the universe are improbably suited to life, which evolution does not explain because it presupposes those laws. Conclude with a judgement, for example that evolution defeats the biological design argument but the cosmological fine-tuning version survives it, so the challenge is decisive against one form but not all.

The marks reward an accurate, analytical account of the analogy and its inference.
Paley argues that if you found a watch on a heath, its intricate parts arranged to tell the time would force you to conclude it had a maker, even if you had never seen one made, because order directed to a purpose does not arise by chance. The natural world, he argues, shows the same marks of contrivance on a far greater scale (the eye adapted for sight, organisms suited to their environments), so it too must have a designer, and that designer is God. A full answer explains the structure of the analogy (from the watch to nature, from contrivance to a contriver) and notes that it is an a posteriori argument from observed features of the world, rather than just retelling the watch story.
