The God Delusion. Richard Dawkins
The God Delusion is a fascinating and compelling insight into the evidence, not only against the existence of God, but a detailed analysis for the evidence for both sides of the argument, and the repercussions this has on society. It makes no attempt to hide its purpose, to enlighten believers to the reason and logic of science, and articulately, passionately and humorously describe the arguments against religion, and for the understanding and respect of science. It is important to note that I am an atheist myself, but do not be deterred by statement, for this book has plenty to offer.
