I read "The God Delusion" by Richard Dawkins almost a year, after which the idea came to me to try to summarise each chapter into laymen's terms (that is, even further... Dawkins is already very skilled in making science easily understandable for the average man). I wanted to do it for me as much as for other people but I never got round to it. Now, I'm determined, no matter how long it takes.
Books by people like Richard Dawkins, Sam Harris, Christopher Hitchens, Lawrence Krauss, A.C. Grayling, Daniel Dennett, etc ... All the authors I have lined up to read =)
My hope is that you read these summaries and are inspired to read the books themselves. If you've already read any of them, I'd be very happy to hear what you think of my summaries.
