Metafilter wonders whether God exists, or more specially, whether that William Lane Craig chap has good arguments for the proposition
By the point I noticed it, the thread had got into people talking bollocks about induction (mainly the sort of nonsense I examine below, but also including atheists who just don’t get what the problems are). I think the tactic Stephen Law calls going nuclear must be in some apologetics manual somewhere, because you certainly see a lot of it about. So, this is how I’d respond to that:
All this induction stuff is very interesting, but let’s go back to shivohum’s original comment.
This uses a standard Christian apologetical strategy (one that Craig has used himself) in response an atheist’s to use of a naive evidentialism to discount religious claims. If an atheist says “All reasonable beliefs require evidence, there is no evidence for God, therefore belief in God is unreasonable”, the clever apologist will ask “All reasonable beliefs? Really? What evidence could there be for your belief that all beliefs require evidence?” They will then go on to point out that it seems we all have to accept some unevidenced beliefs (induction is a good example for the apologist because it’s pretty hard to see how we would get evidence for belief in it without making a circular argument, as Hume knew, but Cartesian doubts about the external world are also popular). “Aha!” says the apologist, “you see, we all rely on faith, and my belief in God, angels, demons and whatnot is just an article of faith, like your belief in this induction thing you’re so fond of. We’re not so different, you and I.”
The atheist’s evidentialism is pretty naive and they probably deserve that sort of response, but still, there seems to be something wrong with equating the rejection of fairly radical sceptical positions with belief in God. I think Chris Hallquist has it right: “belief in the Christian God isn’t very much at all like most of the common-sense beliefs commonly cited as threated by Descartes & Hume-style skepticism (like belief in the reliability of our senses), but is an awful lot like beliefs most Christians wouldn’t accept without evidence–namely, the beliefs of other religions. That kind of response is very hard to reject without special pleading on behalf of Christianity, and doesn’t involve commitment to any potentially troublesome epistemic principles.”
That is, religious beliefs do seem to be the sorts of things that require evidence, as even Christians agree if you ask them what it’d take to convince them of the truth of some other religion. If a Christian were to say, “no, but, you see, it’s only Christian beliefs which are like rejection of Cartesian doubt”, we’d just say “riiiiight“. OTOH, if it’s not just Christian beliefs which are now OK because we all have to rely on faith sometimes, why not be a pagan, Muslim or Pastafarian instead?
I followed up with another comment explaining why Craig gets (admittedly grudging) respect from atheists
