A good defense of agnosticism here. Excerpt:
Atheists have no evidence—and certainly no proof!—that science will ever solve the question of why there is something rather than nothing. Just because other difficult-seeming problems have been solved does not mean all difficult problems will always be solved. And so atheists really exist on the same superstitious plane as Thomas Aquinas, who tried to prove by logic the possibility of creation “ex nihilo” (from nothing). His eventual explanation entailed a Supreme Being standing outside of time and space somehow endowing it with existence (and interfering once in a while) without explaining what caused this source of “uncaused causation” to be created in the first place.
I agree with the skepticism the author aims toward contemporary science and its ability to answer the deepest questions (though at the same time I’ll say we have no better guesses on hand). What bumps me over the edge into atheism, though, is the fact that we have pretty compelling ordinary ways of explaining why people end up being theists, and it would be just too weird a coincidence if theists ended up being right.
Example. I cup my hands together and tell you there is an invisible, massless, chargeless dancing demon in it. I ask you if you think I might be right. I think you ought to say “no, you are wrong” not only because the claim is obviously ridiculous, but also because you know I’m proposing this strange idea only because I’m aiming to make some sort of point about arguments and evidence and theism. You know my motives, roughly, and see how my motives lead me to making this ridiculous claim. Now if it turned out that there really was an invisible demon in my hand — well, shoot, that would really be something, wouldn’t it? Mind-bogglingly weird.
The same goes, mutatis mutandis, for theism. You know why theists believe (all sorts of psychological explanations available here). So if that fully explains why they believe what they believe, then it would be a truly bizarre coincidence for them to end up being right (since certainly the psychological explanations offer no reason for thinking the belief is true; only that it is believed).
Interesting question to raise here: can the exact same sort of argument be raised against the scientistic atheists? Aren’t their beliefs also explicable through psychology? Does that give us reason to discount their beliefs? (Here again I must say: Nz was way ahead of us on this! He ad hominems the scientists alongside the priests in BGE.)
