Diamond, there's a very simple argument I heard someone make as to why they didn't subscribe to the idea of solipsism which fits quite nicely here. The argument is, in short form, that this fellow didn't believe in solipsism because the only proof that could be offered was to disprove it, so why have faith in solipsism if it could only be disproven? I'll try and give a longer form as it pertains to a religious case here.
Atheism postulates that there is no divine being - it is saying that, out of all things that exist, there is nothing that fits a religious definition of a god. This is making a statement which, to conclusively verify it, one must have examined all things enough to verify that nothing in all of existence fits the bill of a divine being Until one has examined all things, one cannot *conclusively* verify that there is no divine being. Talk about what reason suggests, and what a reasonable person would do, all you want - until all things are examined, you're operating from a position which is, at its base, an unsure one. If you commit to the statement that there is surely no god, you take it, at base, on faith.
Now, I don't know about you, but examining every thing in the universe in any conclusive sense seems an impossibility to me, based on human limitations - so, this position of sureness that there is no god figure is unreachable. This means that we can't ever eliminate the possibility that something we haven't examined yet fits the description of a divine being. Thus there are only two states of sureness as to the existence of god that can even be attained - that we find a god and then are sure a god exists, should we find a divine being, or that we are not sure – a state of unsureness.
Now, when confronted with the options of admitting to being ultimately undecided, having faith in the possibility that there is a god figure and we may one day find it, or having faith in the position that there isn't one which we can't ever conclude with sureness... What does rationality suggest there? Atheism seems the only *completely* irrational one because, the moment you prove anything on this matter conclusively, it will be that a god exists, since we've established that we can't prove that a god doesn't. If you bet on atheism, you're betting your lottery ticket is a loser when you *know* you're never going to find out what the winning numbers are. However much probability stacks in favour of it being a loser, if you can't even possibly know, at its base saying "This IS a loser" is a piece of irrational faith.
On a slightly different note, it seems like you have a great deal of faith in reason, and you cite examples of "Am I not supposed to believe that 2 + 2 = 4? It's a fact!" and all that. Well, the great atheist Friedrich Nietzsche has a clever little line of reasoning in The Will to Power's section of biology and the drive to knowledge which always made me chuckle. We look at organs like the eyes or the ears and, if we examine them, we see they are made interact with the outside world in a way to reveal information to us. If we're good evolutionary theorists, of course, we recognize that there was some variation of a process of natural selection leading up to this by which the organ developed the detection abilities that were necessary to its survival in order to reach this point. As such, the eye never developed the ability to detect many things which were inconsequential to the survival of the organism, and there are many things which the ear simply can't hear - this is the way evolution works. Nietzsche even suggests that an organ which is too accurate and revealing may be harmful - if too much information is coming in, too many things which aren't necessary for survival, it will confuse the organism and, for the purpose of survival, make it less effective. Therefore, reason suggests that the pictures painted by each organ is ultimately incomplete, almost by design (attributing design to the universe is a big Nietzschean no-no, but, much easier to speak that way).
Let us then look at our reason. Where does this come from? As I'm sure you're willing to admit, it's no gift from a god (oh wait, I guess we can't be *sure* of that - but indulge me in this little diversion of faith for a moment). In fact, reason suggests that it is a mechanism of the mind, our brain. Reason also suggests that our brain developed in the same way that our eyes and our ears did - and therefore its tool of reason also developed in a similar manner. Think then on the limitation of the eyes and the ears - that there is some information they don't detect, indeed, maybe even information they were made not to detect because such information would be counterproductive to human survival. The picture they paint is incomplete, and though the eye is ignorant of the eye's lack of ability, it’s lack is definitely a fact of the eye. If the eye can be lacking in this way, doesn’t reason suggest that reason, which developed by the same process as the eye, would be subject to the same rules of development – and that reason could also be similarly lacking? Aren’t we then using what could be a flawed tool to examine itself – and yet we’re willing to say that its findings are sure things? Do we trust a microscope which we cannot test other than by examining it with itself? Couldn’t this lead to a flaw in the lens rendering us unable to see a flaw in the lens – leaving us ignorant of the inaccuracy of the instrument, with no way to ever become aware? \
Can't you see how this circularity in trying to verify the accuracy of the instrument applies to your reason, and then complicates any stock you place in the findings of said reason? Our faith in reason stems from our reason analysing our reason and finding it to be a sound instrument. This being the case, when you consider what old Nietzsche considered, it’s only reasonable to admit that reason may in fact be quite unreasonable and misleading – and we have no way to find out. The achievements of human knowledge - scientific included - have been built on a foundation of "Well, we know we can't ever *really* get to the bottom of this, but in the interest of not getting caught in a skeptical web, let's choose what seems like a likely starting point and just going with it." It's unfortunate that some people forget this caveat that lies at the very basis of all human knowledge has built.
I could get into Nietzschean arguments about the world as becoming rather than being, and how even the artifices of mathematics, geometry, and logic are tools aimed at the preservation of the species rather than truth, or even the ever popular Cartesian evil genius argument, but I don’t see any need to get into more sceptical arguments here. What is clear to any reasonable person is that we take reason’s findings on a faith, and if we proceed along that faith, intellectual integrity demands that we not parade our reasonable findings as conclusive truth in any absolute sense – instead, we must do as Nietzsche suggests:
“Let us introduce the refinement and rigor of mathematics into all sciences as far as this is at all possible, not in the faith that this will lead us to know things but in order to determine our human relation to things. Mathematics is merely the means for general and ultimate knowledge of man.”
Now, all this being said, when I realized some of these things myself, I started feeling a bit disingenuous every time I tried to tell a religious person that I knew the truth and they didn’t, and that my reason had led me to this truth. Their arguments may be based on a faith with less evidence than my position (I certainly am not religious!) but I recognize that my position is a contingent one, and the reason I place at its basis is a tool which can't be be tested for accuracy in any truly revealing way, if one heeds its own requirements.
Now, this all being said, don’t’ be so smug when going after religious faith – makes you look silly as your parade your own articles of faith as if they were conclusive facts. In fact, it makes you look like a petulant little kid saying “I TOLD YA SO!” when he finally found some supposed proof that Superman could beat up Batman. I mean, sure, we all know the deck is stacked in Superman’s favour, but we don’t *really* know what the outcome would be, and we are making claims about our rationality, it would be better to rationally admit that then rub Superman’s super powers in a Batman fan’s face.
