The list author says: "Being impolite dinner conversation, religion is rarely challenged. Questioning religion seems oddly disrespectful, almost... sinful. Doubters often privately struggle to figure it out or are influenced by a believer. Many, indoctrinated when young, now demand proof of religion's claimed "truth" which is sheltered in a fortress of faith. Disbelievers are surprisingly abundant but covert (to avoid discrimination) and not organized (there is no need to meet weekly to disbelieve), so there are few accessible opposing sources to consult.
The books listed below were written over the past 250 years (starting with the amazing Spinoza) by people who had questions, thought hard, researched, reasoned, and were kind enough to share. These intelligent, respectful and honest writers investigate religion's "truth". Validated truth is crucial when challenging fundamentalism, evangelism, cults, the prophets of "intelligent design" in public schools or when wondering how religious people can become terrorists. These titles are all excellent. Read a few BEFORE sending your children off to religious schools. (Or if you were one of those religiously schooled children.)"
"The most powerful modern challenge to religion(s) I've seen in many years. I kept saying Yeah! Yeah! He's right! Read this book and see through the propaganda. A MUST read, destined to become a classic."
"Harris has again generated a serious challenge to the status-quo. This book deserves to be read and discussed. He might just have started a well deserved debate that will have profound consequences. Thank you Mr. Harris."
"A quantum leap for those who question religion, but do not have resources nor the time for research. Dawkins has collected, documented and analyzed an exhaustive and persuasive argument in a pleasant readable style that can only be denied by those for whom reason is denied. The best $15 you will have ever spent. Far cheaper than tithing (with better results)!"
"Hutchens seems angry in this book, then justifies his mood in a way that makes you wonder why we all aren't angry. He is another in a long new list of people putting pressure on the faithful to defend their beliefs. This book helps explain why religious defenders are called apologetics. They have a lot to apologize for."
"This is a unique book designed to help parents deal with the challenges of raising secular kids in a sectarian world. It offers practical reasonable examples of how non-believers deal with things like death, morality, supernaturalism, natural disasters, etc. without crediting or blaming supernatural beings. This book is a valuable resource."
"This is an excellent book and worth the read, but the required reading level is high. Onfay writes intelligently about the culture of religion, how and why it can become more athiestic. He encourages Atheology, the atheist perspective, but the translation from French must have been done by a very literate person. It is not for light readers."
"If you haven't read Ingersoll, you are sadly missing the thoughts of a brilliant American mind. In the late 1800s he spoke out against orthodox religion with logic, power and humor and was America's most POPULAR speaker! You will learn much by reading him. He lived his life honestly and is an example of how a human can be good, and smart, without superstition. Read this or one of his other works."
"Paine is responsible for our existence as Americans. You may not know him because he made the mistake of writing this book, his opinion on religion, one of the most thorough bible challenges ever written. Read the reviews!"
"The first 150 pages (of over 500 pages) were interesting. The book tries to remain objective. The author is Mormon. It should be on every Mormon home bookshelf. It seems to be the latest reliable detailed source on Smith, the golden plates, the translation process, and the history of the church."
