Dear Professor Dawkins,
I have just finished reading The God Delusion. Thank you for writing such an insightful, well-argued, passionate and thoroughly enjoyable book.
Until recently, I would have described myself as an agnostic. My reasoning was as follows: the existence of God -or any other supernatural being- can't be proven, but I couldn't see how it could be conclusively disproven. However, reading your book has convinced me it is nonsensical to maintain this theoretical, fence-sitting position. I imagine I qualify as a convert.
It is blatantly obvious that the false comforts offered by religion have no place in the real world. There is absolutely no reason to assume we live on after our physical deaths. Hence, we have no excuse for not making every second of our lives count. Predestination, divine intervention and divine retribution are all man-made fantasies and the responsibilty for taking care of ourselves lies entirely with us. We humans do not need indoctrination and obsolete power structures. What we require is the freedom to make well-informed choices based on critical thinking, responsible behaviour and empathy. And by now we ought to be able to do this without religion.
Finally, I'd just like to mention two books which I personally found very interesting: The Origin of Pagan and Christian Beliefs, by Edward Carpenter and A History of the Devil, by Gerald Messadie. Both offer an interesting insight into the entirely opportunistic manner in which various religions have appropriated bits an pieces from one another to suit their needs.
Kind regards and all the best,
