I wouldn't call deism rational either, at least not anymore. Belief in a non-interventionist impersonal god is about as rational as belief in Sagan's invisible dragon. It made sense in the enlightenment period, back before stuff like evolution and advanced cosmology had made atheism a tenable position for the thinking man, but now that we don't need an intelligence to invoke them I don't see why we should.
Yeah, not cluttering up the metaphysics unnecessarily is my primary reason for not accepting a lot of theist arguments, myself. There's people that disagree that a maximally uncluttered metaphysics is a virtue, though, and from what I've seen where a person falls on that subject is more a matter of taste than justification.
M'not particularly interested in actually providing the arguments that are going around nowadays... I honestly don't remember any of the particulars, nor can I recall (/or am willing to expend the effort finding) enough to hunt them down again. Those were just examples thrown out to show that, y'know, it's not all just FAITH FAITH FAITH NO REASON or whathaveyou (which is overstating Zig's original statement, I do believe, but it gets the point across.). Yes, a lot of the older stuff's been kicked into the ground pretty hard and etc, and so forth, and so on. That doesn't mean we get to posit the assumption that, simply because an argument is faith (and/or religion) based, it's irrational. S'not paying th'better theologians their fair due, and the issue isn't quite that simple.
(As a side note, I too have not found much in the way of specific logical theologians. I search for them every once and a while, but the closest I have ever come to finding them is the Anthropic Principle, which basically consists of assigning physical laws probabilities in order to make a gap into which a god can fit.)
Yeah, s'like I've been saying, I'm aware that they exist but don't remember exactly who they are... frankly, I'd have to make either a long distance phone call (am poor
) or a six hour road trip (in about a month and a half, when they come off vacation
) to talk to a couple of my old professors to get some good suggestions. Theology isn't really my field, I've just brushed up against it enough to have a degree of respect for it, even if I by-and-large disagree with the conclusions it tends to come to (and basically don't remember a bloody thing about the actual arguments). It's never good to underestimate the enemy, so to speak
As for the faith thing, just remember to clarify religious faith with that, heh.
Everything's ultimately faith (i.e. unjustifiable -- in the stronger sense -- belief) based at the bottom, etc. Faith isn't just a worthwhile thing, it's a
necessary thing. Strong skepticism can't actually be beat without it, unfortunately, and thorough skepticism itself is basically a useless dead-end.
