This is a good book which argues the idea of faith and god very thoroughly and logically. I believe in God and when I read this book, I tried on my own to counter each of his arguments against God, but found that I couldn't. He thorougly demolished any argument you could have to believe in God. I still believe in God, but as Smith might say, I do so irrationally. Everyone, even religious people, should read this book with an open mind and see how their beliefs hold up!
