I lost my faith at thirteen. Not because of an argument. Because of accumulating doubt, and because the story stopped being coherent from the inside. I had never read anything like The God Delusion. The leaving happened before I was old enough to have read much at all.
Reading Dawkins now is a strange experience. The book is written for people who need permission or argument to leave, or for confirmed atheists who want their position clearly articulated. For someone who left quietly, through experience rather than argument, reading it is a bit like being handed a map of a city you moved out of years ago. The map is accurate but you don’t need it anymore. What you actually want is to understand why your family still lives there.
That said: The God Delusion contains some genuine thinking worth engaging and some significant weaknesses worth being honest about.
What Dawkins gets right
The book’s best contribution is the argument from improbability. If you invoke God to explain the complexity of the universe, God must be more complex than the universe. You have not explained complexity. You have relocated it. This is a genuine philosophical point, not a rhetorical one. Dawkins calls it the Ultimate Boeing 747 gambit, and it forces anyone using complexity as evidence for God to explain how God avoids the same problem. Most cannot.
Natural selection is the actual answer. It builds complexity upwards from simplicity through cumulative small steps. No designer required at any stage. Dawkins explains this with real clarity. The distinction between a crane (which builds upward from what exists) and a skyhook (which imposes from outside) is a useful one well beyond biology. Any explanation that accounts for complexity by positing something even more complex is doing skyhook work.
The moral zeitgeist argument is also strong. Morality has improved across all societies over centuries: slavery abolished, rights extended, torture condemned. These improvements happened in societies with unchanged scriptures. The Bible has not changed. Something else is moving moral standards forward. Dawkins is vague about what, but the empirical observation stands. Religion is not the driver of moral progress. It often lags it.
Where the argument overreaches
The problem with The God Delusion is the opponent Dawkins has chosen. He is extraordinarily effective at demolishing young-earth creationism, biblical literalism, and the God of the gaps argument. These deserve demolishing.
But Aquinas didn’t hold those positions. Plantinga doesn’t. Tillich’s concept of God as the “ground of being” is not the personal, interventionist deity Dawkins is refuting. The theological tradition Dawkins argues against is, at best, a caricature of what sophisticated religious belief actually claims.
He is aware that these traditions exist. He dismisses them too quickly. His treatment of the ontological argument is particularly weak. He admits he cannot immediately say why it fails, then offers a response that most philosophers do not find convincing.
This does not mean Dawkins is wrong. It means the book does not close the case it claims to close.
A tension the book does not resolve
Dawkins uses moral language throughout. The God of the Old Testament is “monstrous.” Religion causes “harm.” Certain practices are “wrong.” But on his own framework, morality is an evolved trait shaped by evolutionary pressures. It is useful, not objectively true. If that is what morality is, it is not clear what gives Dawkins’ moral judgments any more authority than anyone else’s. He does not address this.
Haidt’s The Righteous Mind helped me see why this gap matters. Haidt showed that people do not form beliefs through argument and then apply them. They form beliefs through experience and intuition and generate arguments afterwards. Dawkins writes as if the right argument will move the right person. Haidt’s evidence is that it almost never works that way. Especially not on sacred beliefs.
(I wrote a full piece on Haidt’s moral foundations argument here.)
What the book is actually good for
The God Delusion is most valuable as popular science. The evolutionary argument, the probability argument, and the moral zeitgeist data are all worth reading carefully. As philosophy, it is thinner. As an attempt to understand religion, what it actually is, why it persists, what it does for people, it is thin.
The books that answered those questions better for me were not defences of religion. They were Sapolsky on the neuroscience of in-group behaviour and ritual, Kahneman on the cognitive biases that make supernatural thinking feel natural, and Haidt on why moral belief is not primarily a rational process.
(Full pieces on Sapolsky’s Behave and on Kahneman’s two systems are on the blog: behave and thinking-fast-and-slow.
Dawkins gives you a map out.
He doesn’t give you tools to understand why people who think clearly still live there.
I am reading Alister McGrath’s The Dawkins Delusion next.
McGrath is a former atheist who became a Christian after studying biochemistry at Oxford. He wrote it specifically as a response to this book. I want to see which objections land.
The study pack for both books
I build one of these for every book I read. These two come as a single twenty-one-page PDF, because reading them apart is most of what goes wrong with them: a briefing written to be read before you open Dawkins, structured notes in twelve blocks covering both books and the comparison, the five ideas that survive if nothing else does, connections to five other books, a seven-day test on how you hold a position, and 38 flash cards in four formats.
If you want to see the standard before you spend anything, The Doors of Perception pack is published here in full and free, nothing held back.

The reading and the arguments are mine. I write here to find out whether I have understood what I read, because explaining something is the cheapest way to discover whether you actually understood it or only recognised it.
AI is the other half of that. I argue with it, it pushes back, and what you are reading is what survived. English is not my first language, so it also helps me produce the clean version.
Nothing goes out that I could not defend if you asked.
