I was really disappointed by this. I actually picked it for a group read with some friends, having read Keller before and been impressed by him. I wasn't impressed with this.
The full title of the book is The Reason for God: Belief in the Age of Skepticism. And the back suggests that Keller "addresses the frequent doubts that skeptics...have about religion." And goes on to say that "Keller explains how the belief in a Christian God is, in fact, a sound and rational one." And then, "to skeptics, atheists, and agnostics, he provides a challenging argument for pursuing the reason for God."
Unfortunately, I feel like he didn't meet this at all. Let me caveat this by saying that I do believe in God. My point here is that, if I didn't, this book wouldn't sway me an inch.
The first half of the book addresses several skeptic arguments. But they are really straw men in comparison to real skeptic arguments. Instead of addressing things like, "I see no evidence to indicate that there is a personal God described in the Bible," he addresses things like "Christianity is too exclusive" and "there can't just be one religion". The more I think about it, the more I feel like he's just trying to argue that Christianity is better than the other world religions. Which is completely different than arguing for the existence of the Christian God.
The second half of the book gives reasons to believe in God. This would be better addressed to evangelicals as Keller's "this is why I believe in God." A couple are somewhat compelling, and might have value to strengthen the faith of someone who is already a believer, but as any sort of proof or evidence, they are a poor apologetic.
Keller starts off in this book on the wrong foot. In the first chapter ("There Can't Just be One True Religion), I counted 6 different logical fallacies alone.
1. Bandwagon. This suggests that something is true because everyone believes it. (It's a fallacy because things need to be argued on their own merits, not because everyone thinks they're true.) Keller states: "Religion is not just a temporary thing that helped us adapt to our environment. Rather it is a permanent and central aspect of the human condition." In other words, I read, it's always been here, it's always going to be here, therefore God exists?
2. Burden of Proof. This one is his favorite. He tries to put the burden of proof on those that do not believe; but the burden of proof is on those that do. If you say unicorns exist, and I say they don't, the burden of proof is on you to prove they exist. If I say "God exists" and you say "I don't see any evidence for God" then the burden of proof lies on me. But he wants to put them in the same camp, as if "believing" God exists and "believing" God doesn't exist are the same thing.
3. Tu Quoque. (Pronounced "too kwo-kwee".) This is the "so are you!" argument. He wants to suggest that Christianity is better, but rather than presenting proof that it is, he just says that "the insistence that doctrines do not matter is really a doctrine itself." In other words, instead of presenting evidence that God holds us to a specific doctrine and way to live and worship; Keller responds that if we don't think he holds us to a specific doctrine, then that's the specific doctrine we believe he holds. Yes, it's very confusing.
4. Generalization. He likes to use this in reference to "secularists" and "atheists." "Skeptics believe that any exclusive claims to a superior knowledge of spiritual reality cannot be true...They believe the world would be a better place if everyone dropped the traditional religions' views of God and truth and adopted theirs." C'mon, Tim - that's not true of everyone.
5. Straw Man. This is related to Generalization in that, if he can generalize atheists enough, he can set up a straw man to knock down. He says, "For example, some think that this material world is all there is, that we are here by accident and when we die we just rot, and therefore the important thing is to choose to do what makes you happy and not let others impose their beliefs on you." I realize he says 'some', but this is a commonly held belief of non-believers by believers: 'Non-believers don't really have morals'.
6. No True Scotsman. This is his second favorite - he does this a lot later in the book, too. But toward the end of chapter 1, he describes a Christianity I would believe in, but don't see practiced, and compares it to other religions. "Most religions and philosophies of life assume one's spiritual status depends on your religious attainments." He doesn't come out and say it, but if I were to argue that I don't think a lot of Christians practice the things he suggests makes a true Christian, he would argue 'That's not real Christianity.'
And that's just chapter 1!
He uses the No True Scotsman fallacy all through the book - describing a Christianity that may reflect the teachings of Jesus, but that do not reflect the actions of the millions of Christians around the world. He makes many statements about all Christians that may apply to a few - but definitely don't apply to the majority of the ones I've known. (For example: Christians don't believe they are saved based on how good they live their lives. Or, Christians know that because they are flawed many people who aren't Christians will be more morally upstanding. I'd like to meet those Christians, Tim!)
He sets up atheist straw men throughout the first half of the book, too. He doesn't address people who have investigated belief in God and come away with the belief that there isn't enough evidence to support the belief in the personal, Christian God. Which to me would be the biggest reason to be an atheist. Not just because "a loving God wouldn't send people to Hell."
In chapter 2 (How Could a Good God Allow Suffering), he suggests that if you think anything is bad or "evil", you are stating a belief in God. His argument seems to go something like this: (1) Evil exists. (2) If evil exists, then good exists. (3) If good exists, it was created by God. Therefore, since evil exists, there is a God. He goes on to quote Dostoevsky, basically saying we should believe in God because it consoles us in our suffering. Nothing in this chapter argues a reason for the existence of God. Just for a belief in God - because it makes us feel better.
Chapters 3 through 7 are just as flawed. Filled with fallacies, they knock down straw man arguments, make generalizations about skeptics, and use an ideal (perfect) version of Christianity in their arguments (rather than the real (flawed) version of Christianity that exists).
The rest of the book are arguments for God. The first chapter of this section isn't terrible, but it is lacking. Looking at the creation, at beauty, this is an argument for Deism, but not necessarily the Christian God. Morality proving God is just a re-work of an old C.S. Lewis argument. The idea that because we need meaning in our lives proves that there is a personal God is a poor argument.
And some of the valid points point toward Deism - but just because you believe in God doesn't mean you believe he did everything that the Bible describes.
And the rest of the points have to do with Christian theology. The cross. The resurrection. Which would all be great things in a book written for Christians about "why Tim Keller believes in the Christian God", but not in a book to prove to skeptics that God exists.
One thing that really bothered me Keller quoting N.T. Wright at the end of chapter 7. They both seem to agree that if the resurrection stories in the Gospels didn't happen exactly in the way they described, then there is no point to being a Christian, following God, or indeed caring for other people. This just seems like really shitty theology. From both Keller and Wright.
And then, finally, we come to the last paragraph of the book. I realize I'm missing the point of this last paragraph; Keller is trying to say that God seeks us. But in this (true according to Keller) story, the person searching for God keeps praying, "God, help me find you." And God continually ignores her. But someone told her to, instead pray, "God come and find me." And then He did.
What I want to say to Keller here is that if you want people to believe in an all-powerful, loving, personal God, don't make Him out to be some sort of petty asshole that ignores people's honest pleas, until they change that to very specific language.
Would a loving God really do that??
