Religion and morality[edit]
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"[21] 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.[22]
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, Dawkins states, morality does not originate from the Bible, rather our moral progress informs what part of the Bible Christians accept and what they now dismiss.[23]
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.[24] 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.
