This is a strange book to review, because it is so decidedly sure of itself in ways that I cannot necessarily agree with. However, I will say that it is compelling, and brings very large concepts down to accessible writing. For these factors alone, I have to commend it!
Mr Severino attempts to explain how humans can, logically, "know" there is a God. I err on the theist side myself, although I perhaps have more humility about my human condition than Severino. He puts a lot of trust in deducting God's existence from the world we experience around us as humans. Especially at the beginning of the book, he does a very good job of explaining why one can be fairly sure of God's existence in ways that I had already "felt," myself. He even throws in a few surprises in his logic puzzles that I had never quite thought about and was not expecting. The influence of C.S. Lewis is obvious, but Severino is actually much clearer and more no-nonsense than what I have read of Lewis books like Mere Christianity.
However, on the negative side, the book is sometimes rhetorically annoying. There are repeated phrases that sound conversational at best, and as though he is talking down to the reader at worst. Just as well, though the author's confidence is admirable, someone with as much doubt as I have doesn't find his logic as convincing as he does. Perhaps his courage, though, wins me over on this one.
I'd still love to hear the atheists rip this one apart ;) For now, kudos, Mr Severino, and thanks for appearing on the Busted Halo radio show which led me to this work.
