A donor who wishes to remain anonymous has commissioned on my behalf a print publication of a slightly updated version of my 2006 essay "Why I Am Not a Christian." All proceeds will go to me. He just wanted it to exist so he could hand it out to door knocking evangelists, and make other handy uses of it in his own atheist evangelism. At the donor's request (and generous payment) I made several minor additions and some changes, to get its content up to date. It is available in print and kindle.
For those unfamiliar with the original, it explains the four reasons I do not accept the Christian religion, describing four facts of the world that, had they been different, I would believe. Those four reasons are God's silence, God's inaction, the lack of evidence, and the way the universe looks exactly like a godless universe would, and not at all like a Christian universe would, even down to its very structure. I address all the "usual" replies to these claims, in ways you might not have heard before, relying on my wide experience in debating and studying these issues all over the world for more than fifteen years.
In this version I am brief, clear, and down to earth, covering the whole topic in under ninety pages of easy-to-read explanation. My donor is right, it does make a perfect book to introduce yourself, or your friends, to why fewer educated people are embracing Christianity than ever before, and is ideal for handing out to door-to-door missionaries. I don't expect everyone will want one (it's content isn't new), but for the above uses it's handy and cheap, and makes for an easy read. I'll be selling copies at all my upcoming venues.
