This series of articles takes a look at the content of the bestseller, "The God Delusion", and then goes on to recommend a number of books which credibly deal with objections to belief in God and Christianity

The God Delusion is a 2006 bestselling non-fiction book by British biologist Richard Dawkins, professorial fellow of New College, Oxford, and inaugural holder of the Charles Simonyi Chair for the Public Understanding of Science at the University of Oxford.

In The God Delusion, Dawkins contends that a supernatural creator almost certainly does not exist and that belief in a personal god qualifies as a delusion, which he defines as a persistent false belief held in the face of strong contradictory evidence. He is sympathetic to Robert Pirsig's observation in Lila that "when one person suffers from a delusion it is called insanity. When many people suffer from a delusion it is called religion."

As of January 2010, the English version of The God Delusion had sold over 2 million copies. It was ranked #2 on the bestsellers' list in November 2006. In early December 2006, it reached #4 in the New York Times Hardcover Nonfiction Best Seller list after nine weeks on the list. It remained on the list for 51 weeks until 30 September 2007. The German version, entitled Der Gotteswahn, had sold over 260,000 copies as of January 28, 2010.

It has attracted widespread commentary, with many books written in response.

Dawkins has argued against all creationist explanations of life in his previous works on evolution. The theme of The Blind Watchmaker, published in 1986, is that evolution can explain the apparent design in nature. In The God Delusion he focuses directly on a wider range of arguments used for and against belief in the existence of God (or gods).

Dawkins had long wanted to write a book openly criticising religion, but his publisher had advised against it. By the year 2006, his publisher had warmed to the idea. Dawkins attributes this change of mind to "four years of Bush". By that time, a number of authors, including Sam Harris and Christopher Hitchens, who together with Dawkins were labelled "The Unholy Trinity" by Robert Weitzel, had already written books openly attacking religion. According to website, the book led to a 50% growth in their sales of books on religion and spirituality (including anti-religious books such as The God Delusion and God is Not Great: How Religion Poisons Everything) and a 120% increase in the sales of the Bible.

The book contains ten chapters. The first few build a case that there is almost certainly no God, while the rest discuss religion and morality. In dedicating the book to his late friend Douglas Adams, Dawkins quotes Adams' Last Chance to See: "Isn't it enough to see that a garden is beautiful without having to believe that there are fairies at the bottom of it too?"

Dawkins writes that The God Delusion contains four "consciousness-raising" messages:

  1. Atheists can be happy, balanced, moral, and intellectually fulfilled.
  2. Natural selection and similar scientific theories are superior to a "God hypothesis"—the illusion of intelligent design—in explaining the living world and the cosmos.
  3. Children should not be labelled by their parents' religion. Terms like "Catholic child" or "Muslim child" should make people cringe.
  4. Atheists should be proud, not apologetic, because atheism is evidence of a healthy, independent mind.

Since there are a number of different theistic ideas relating to the nature of God(s), Dawkins defines the concept of God that he wishes to address early in the book. Dawkins distinguishes between an abstract, impersonal god (such as found in pantheism, or as promoted by Spinoza or Einstein) from a personal God who is the creator of the universe, who is interested in human affairs, and who should be worshipped. This latter type of God, the existence of which Dawkins calls the "God Hypothesis", becomes an important theme in the book. He maintains that this existence of such a God would have effects in the physical universe and - like any other hypothesis - can be tested and falsified.

Dawkins surveys briefly the main philosophical arguments in favour of God's existence. Of the various philosophical proofs that he discusses, he singles out the Argument from design for longer consideration. Dawkins concludes that evolution by natural selection can explain apparent design in nature.

He writes that one of the greatest challenges to the human intellect has been to explain "how the complex, improbable design in the universe arises", and suggests that there are two competing explanations:

  • A hypothesis involving a designer, that is, a complex being to account for the complexity that we see.
  • A hypothesis, with supporting theories, that explains how, from simple origins and principles, something more complex can emerge.

This is the basic set-up of his argument against the existence of God, the Ultimate Boeing 747 gambit, where he argues that the first attempt is self-refuting, and the second approach is the way forward.

At the end of chapter 4, Why there almost certainly is no God, Dawkins sums up his argument and states, "The temptation [to attribute the appearance of a design to actual design itself] is a false one, because the designer hypothesis immediately raises the larger problem of who designed the designer. The whole problem we started out with was the problem of explaining statistical improbability. It is obviously no solution to postulate something even more improbable." In addition, chapter 4 asserts that the alternative to the designer hypothesis is not chance, but natural selection.

Dawkins does not claim to disprove God with absolute certainty. Instead, he suggests as a general principle that simpler explanations are preferable (see Occam's razor), and that an omniscient and omnipotent God must be extremely complex. As such he argues that the theory of a universe without a God is preferable to the theory of a universe with a God.

The second half of the book begins by exploring the roots of religion and seeking an explanation for its ubiquity across human cultures. Dawkins advocates the "theory of religion as an accidental by-product – a misfiring of something useful" as for example the mind's employment of intentional stance. Dawkins suggests that the theory of memes, and human susceptibility to religious memes in particular, can explain how religions might spread like "mind viruses" across societies.

He then turns to the subject of morality, maintaining that we do not need religion to be good. Instead, our morality has a Darwinian explanation: altruistic genes, selected through the process of evolution, give people natural empathy. He asks, "Would you commit murder, rape or robbery if you knew that no God existed?" He argues that very few people would answer "yes", undermining the claim that religion is needed to make us behave morally. In support of this view, he surveys the history of morality, arguing that there is a moral Zeitgeist that continually evolves in society, generally progressing toward liberalism. As it progresses, this moral consensus influences how religious leaders interpret their holy writings. Thus, morality does not originate from the Bible; rather, our moral progress informs what part of the Bible Christians accept and what they now dismiss.

The God Delusion is not just a defence of atheism, but also goes on the offensive against religion. Dawkins sees religion as subverting science, fostering fanaticism, encouraging bigotry against homosexuals, and influencing society in other negative ways. He is most outraged about the teaching of religion in schools, which he considers to be an indoctrination process. He equates the religious teaching of children by parents and teachers in faith schools to a form of mental abuse. Dawkins considers the labels "Muslim child" or a "Catholic child" equally misapplied as the descriptions "Marxist child" or a "Tory child", as he wonders how a young child can be considered developed enough to have such independent views on the cosmos and humanity's place within it.

The book concludes with the question whether religion, despite its alleged problems, fills a "much needed gap", giving consolation and inspiration to people who need it. According to Dawkins, these needs are much better filled by non-religious means such as philosophy and science. He suggests that an atheistic worldview is life-affirming in a way that religion, with its unsatisfying "answers" to life's mysteries, could never be. An appendix gives addresses for those "needing support in escaping religion".


In order to fairly and systematically look at the pros and cons for religious belief, it is important to seriously examine all sides of the argument. So I strongly recommend that to begin with the interested reader buys or borrows "The God Delusion" and reads it in detail. The writing style of the book is very accessible and gripping and while Dawkins goes over the top at times – and sometimes indulges in theories ill-befitting a top class scientist – nonetheless "The God Delusion" is the best "one stop shop" for becoming acquainted with well argued reasons for not believing in God. There are broad swathes of Dawkins' book which you can skip in order to concentrate on the core material. Chapters 3 and 4 are the key sections. 

If in seeking credible responses to Richard Dawkins' arguments you fancy plunging into the deep waters of highly technical intellectual argument and analysis, then the best book to consult is “Reasonable Faith” by William Lane Craig. Please go to the article below entitled "Reasonable Faith: Christian truth and apologetics" to read an introduction to Craig's work.
