For dummies books arent really for dummies. They are just written in a way that anyone can completely understand the topics, without even having heard of it before.
A great video steph. It's the first I've heard of Hermant Mehta and friendly atheist. Has he written anything?.
He runs what is probably the most popular atheist blog in the world.
Among others, I would add to Hemant's list: Deconverted: A Journey from Religion to Reason, by Seth Andrews of The Thinking Atheist. His is the story of a person who was raised and indeed steeped in religion, who because of events in his life and his own curiosity, came to the conclusion that his belief system made no sense. The point is that he's a regular guy who figured it out and has since become one of the great lights of the atheist community.
Similar to that is Dan Barker's Godless: How an Evangelical Preacher Became One of America's Leading Atheists. Yes, it is another story of deconversion, but in this case, the subject was a genuine bible-thumper who had been determined with amazing fervor to bring people to Jesus before he came to his own epiphany about his flawed faith. I haven't quite finished Godless yet, but it has been an excellent and engaging read.
I shall buy them two Loren.
