By the intensity in believing in a god, people can be stratified as following seven groups.
1) I sense/know/seen (etc) god, and I believe 100% that god exists.
2) I know people of group 1, so I believe in god and its existence.
3) I am not sure about god and his existence, but I choose to believe in it.
4) I am not sure whether god exists or not
5) I am not sure about god and his existence, but I choose not to believe in it.
6) I have some evidence to not to believe in god and 90% sure that it doesn't exist.
7) I am 100% sure that there can be a god, and I deny any god/gods and it's existence.
Before this book, I was in group 6 and slowly moving to 7.
I was walking, very slowly on that road. This book pushed me in the back, made me run some distance towards group 7.
A great read. Actually, a must read for every sane person.
Looking back, I realise I had a rationalist in me, ever since I was a kid. Still, I chose to be a "good Muslim kid" by believing in believing. I had my doubts in teachings of ustad's in madrassas. Tried reading Quran in my mother tongue and found several contradictions. Asked the people about it who I thought were knowledgeable enough to provide me answers but to no avail. Ever since I had resources available, I exploited it for my answers.
I came to terms with it only four years ago, by coming out of the closet and proudly announcing that I am a rationalist/atheist.
I hope this book will answer a lot other people's questions which they have buried in them.
