The God Delusion
Why this book?
This was the book that impelled me to write my own account of superstition. I could have also recommended his masterpiece, The Selfish Gene, which I read as a teenager and got me into science in the first place but this unforgiving attack on religion spurred me to write a more balanced view that considered religion as a naturally emerging consequence of cognitive development. In fairness, The God Delusion does briefly mention evidence in support of a natural inclination, but this is outweighed by an agenda (that I do not share) to eradicate religion as pernicious indoctrination. Whatever your opinion of Dawkins, he is undeniably one of the most gifted science writers with a clarity of argument combined with a poetic beauty of prose.
