Dear Professor Dawkins,
I do not know whether or not you will read this, but I am certain there is a better chance that you will read it than that some deity will hear my thoughts while I type it.
I cannot claim that I have just recently lost my religious faith, but certain ideas I had already thought (and many that I hadn’t!) became much clearer to me as I read The God Delusion. You must have gone through great pains to address each argument as completely and logically as possible. I want to thank you not only for cementing in my mind a strong foundation for rational thought, but also for being courageous, as you go against some rather delusional (to use your word) and sometimes radical opponents: a potentially hazardous combination.
From before I was a teenager, it bothered me that any religion could make a claim that it was the only right one. I figured that the only solution was that they had to all be wrong, and I made up my own theory – that God manifested him/herself in different ways according to what would work best for different peoples throughout history. Admittedly, I prayed quite often in my teenage years, and even had some superstitious quirks, but I slowly became more skeptical as I learned more about how the world works and wondered more and more about the incompatibility of the idea of a benevolent, all-powerful god with a cruel world full of religious wars and natural disasters. Finally, when I was about 20, I stopped believing in the supernatural altogether. I came across your book when I was 24, and it was like a breath of fresh air.
I wish you the greatest success in encouraging religious people to think for themselves and to raise questions about things which they’ve formerly taken for granted. It is a worthy and noble cause.
