I think that if you understand how evolution works on a really intuitive level — how blind it is — it's very difficult to believe both in human evolution and a guiding divinity. "Genes which promote their own replication become more common over time" is not a principle which admits of purpose. Vaguer understandings of evolution's actual mechanism probably contribute to the apparent reasonableness of "theistic evolution".
Sorry, but that sounds like motivated stopping to me. Coming up with ways by which blind evolution and guiding divinity might be compatible isn't really hard at all.
For one, a gene mutation can only be selected for once it exists. Whether a mutation comes into existence or not is a random process. God could influence the mutations that come into existence.
Secondly, the course of evolution is determined by the environment. Put life in a cold environment, and it will evolve to have adaptations for the cold. God could manipulate the environment to select for ...
In an Open Thread comment beriukay mentioned that he's reading C.S. Lewis' Mere Christianity. I've been reading it too, for interesting reasons.
In my case it so happened that I started discussing faith with a long-time online friend whose spiritual views I didn't yet know, and he turned out to be a Christian with a high regard for the Bible, who also has an interest in science. As our discussion turned to our readings on spirituality, I acknowledged (I think it was me) that I probably spent more time on books that reinforce my point of view than on books that challenge it, perhaps a case of confirmation bias. (I've been exposed to many poor arguments for Christianity, and dismissed them; but possibly that was largely a function of having started out with that bottom line already written and picking arguments I wouldn't have much trouble refuting.)
In the spirit of experiment we agreed to a "trade" - he would read (thoughtfully and with an open mind) a book of my choosing on reasons to doubt faith, and I'd do the same with a book he chose on Christianity.
So the idea here is to pick a book that's the "best argument from the other side" (as in quote 3 here).
I recommended The God Delusion - I'm not sure if that's the best choice given the above intent, but it's what came to mind on the spot.
Would you make a different choice? If so, what?
