And if you massacre coyotes and deport grey wolves so that the alleged red wolf "species" will not have sex with other canids, what are you doing?
If you slaughter barred owls so that they will not compete with or have sex with spotted owls what are you doing?
We are preserving dead wood so that spotted owls will have suitable nests, but due to fire prevention, there is a lot more dead wood in forests than would ever happen naturally, a lot more dead wood than there ever has been in the history of the earth. The spotted owl really is an inferior species to the barred owl - and female spotted owls don't seem to think it is a species at all.
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?
