"If we surround ourselves with only like-minded individuals, we won't grow intellectually or spiritually." Someone said that to me. "Disagreement and debate is what makes this country great." I hear variations of that one, too, like, "It's our differences that make us stronger." These are very pleasant things to say and hear, very politically correct when you're at odds with someone, very along the lines of agreeing to disagree. But they're actually pretty stupid if you put any amount of thought into them. (It's okay for me to say that despite your disagreement, because by your logic I'm causing you to grow; I take comfort in knowing that you cannot abandon me for such derision, or your well-being might suffer.)
It makes zero difference what anybody thinks about something that is true. Well, I shouldn't say zero, because the fools who ignore truth and pretend there is an alternative can actually do unknowing harm if avoidance has consequences. If you're about to be hit by a train (I choose a train in this example because I like the imagery of something that has no course but one unless derailed), and I see it plainly and have the opportunity to push you out of its way, if I see that you are not in motion to remove yourself from its path--whether you are aware of your impending meeting or not--it is fair to expect that I should act in your interest and attempt a rescue. (The whole principle of fairness has fantastic wealth of material in itself, but for now I'll just pass right through it to get on to the point.) Now there are those whose idea of a rescue is try and derail the thing, but a more likely productive effort would be to focus my energies in the moment entirely on getting you quickly out of its way. The thing still proceeds, and may yet find others on the track ahead, but you the individual are past its danger. If the train is a dumb idea like atheism, it is fairly senseless to try and derail it if you can safely remove the individuals one by one that it might strike, and it is fine if a dumb idea like that runs its course without splattering anyone. In that regard, the response of many with religious inclinations to those without has been counterproductive, because many would rather be hit by a train than with a Bible.
There's something else I should give equal treatment to, and that is that truth is truth regardless also of faith. Believing anything will not make it true; it will only make your perception that it is true, which can accurately be called out as delusional if it is not, though by that point you very likely do not care. So anyone who says anything about faith in trying to prove or disprove anything is just being silly. It is possible, however, for truth to strengthen faith, which I believe is what most of the anti-religious are hoping for. But you must first be willing to accept truth and see it for what it is.
Since I've decided to pick on atheism (more accurately agnosticism, because it is not possible for a creature to not believe it was created, so we are really only dealing with denial, which is only a lie to oneself and not a valid system of belief), we benefit from considering something important about some terms frequently thrown around in the discussion. "Proof" is one, which leads to things like "facts" and "evidence", and often borrows from scientific approach, and is suggestive of a courtroom drama in which cases are laid out before a determination is made. I'm equally as happy to work within those confines as without, so let's lay a very important foundation and proceed from there. Let's think about what proves a thing--what makes it factual. Usually when someone tells me they want proof of God, they go on to describe something very tangibly present before them, usually a personified God himself right in the same room, performing miracles. Now when Jesus was on earth, tangibly present, performing miracles--indeed, raising from the dead--people still chose not to believe. So what proof are people really asking for that they would be willing to accept? I don't have a good answer to this, but I suspect it would look very much like a personal genie, which is certainly what many people suppose God is. But then, that wouldn't be much of a God, would it? That's much more of a mythology than what an actual God would need to be. An actual God could not be fully contained within its own creation; it could be present and evident, but would certainly have to be larger and operate on a much grander level.
So, does that mean, since an infinite God cannot be fully grasped in a finite scope, that it is unprovable and can therefore not be true, or at least not known? Of course not. If something is true, it is proof of itself. Since we think linearly, let's think of it as a crime scene. The truth is what we are trying to glean, through what? Evidence. So evidence is a sort of presentation to those who were not present of a perception of something true and real that definitely happened. If it cannot be convincingly presented to, let's say, the jurors and judge, did it still happen? Absolutely. And individuals hearing the body of evidence may find it sufficient or insufficient to convince them--the hardest skeptic in the room may require more than someone who doesn't care so much and would accept sooner than doubt, and that is why we generally seek consensus in matters of law, because there is in fact a sort of safety in numbers when we are able to transfer responsibility across a broader populace and assume less of it for ourselves. (This may actually be why we vote on anything at all--not because agreement makes something correct, but because another's surety can cause us to err with confidence and not much accountability.)
So, again, if something is true, its truth is its own proof, and its proof depends on its truthfulness, which is why only it has the authority and power of testifying about itself with any legitimacy. Truth testifying about itself is safe to take at its word, but untruth testifying about truth cannot be trusted. Whatever is fallible, whatever can be discredited, cannot contribute to the gleaning of truth and therefore has nothing to do with it, but it can effect our individual perceptions of truth, and that depends entirely on what we are willing to accept. So whoever asks for proof of God has not yet accepted the proof already in front of them. It is not that God cannot be proven, because truth is proven simply by existing and being true; it is that a person has not yet accumulated enough of whatever particular evidence they are looking for to move from unbelief to belief--which, again, has no bearing on the truth itself (I would hate to think I've been unclear about that point). There is no deficiency in the truth, but only in our knowledge of it, and I suppose this is the point where faith comes in. Faith is not a substitute for evidence--that sounds rather more like stupidity--but it holds off its revelations of perception until the threshold at which an individual's criteria for evidences has been met, and takes over from there. Now, things get muddled (maybe intentionally so) when people use the word "fact" interchangeably with "evidence", when it should in fact be interchangeable only with "truth". It is misrepresentative and deceptive to say "provable fact" when you mean "evidenced truth". All fact is proven by merit of being true; what you are instead looking for is enough evidence to overcome a preexisting bias--whatever personal impediment you've been nursing--to allow yourself to see truth for what it is. Where communication of that breaks down is in the false assertion that the variances of processing and accepting information somehow make the information itself relative to the hearer. No, only perception is relative, while truth remains 100% factual, proven truth, not at all threatened by anyone's inability to conceive of it.
That was the main thing I was concerned with for this writing, so now we can think about the implications on people who hold disagreement as some sort of lofty ideal. If you tell me you can't grow unless challenged by dissent, you're telling me that your perception of truth is relative and alterable, and that suggests to me that you are seeking consensus in order to validate presuppositions which have nothing to do with accuracy. When you agree to disagree, while you may both perceive yourselves correct, only one of you actually is. To consider it tyranny for the correct to stand by their correctness is just foolish; and it is a foolishness they in the wrong will likely also confront once their perception has changed, and their obstacles to belief have been surmounted, and they finally lay claim to the benefits of truth. Is it really our differences that make us stronger, or is it that one of us is actually right? We would be stronger if both of us were right, but in the absence of that, the one who is can probably carry the one who isn't a good bit of the way before being worn out by exhaustion.
So rather than praising conflict, it would be better if each party would attain sufficiency of faith for themselves, then truth could guide both and the collective group could go much further than if some remain burdensome. If not being on the same page really was beneficial, we would pair kindergarteners with grad students, and put laypersons in executive roles, and mix sporting leagues without any kind of detriment. But no, beginners learn together as beginners, then advance to intermediate levels, and hopefully again to expert when they have mastered enough of the skills to demonstrate proficiency and be reliable to instruct others. This can be taken as arrogance or accepted as the progression of wisdom. You can pretend to be an expert in matters you know nothing about, or you can accept your limitations and work to overcome them. But you cannot with any convincingness say to an expert that he is not or cannot be an expert because you yourself are not, and it must therefore be impossible. And you cannot say truth cannot be proven simply because it hasn't met your flawed (and by that I mean relative and alterable) criteria for processing it.
If my arguments can be useful to you, wonderful, but if you're unable to see what I see as truth, the missing pieces for your perception are for you alone to glean. There is a point where you yourself become convinced by your own nature inside you that truth is as laid out and apparent and easy to accept as it is to a child, because it does not ultimately depend on anything we understand, but it is rather staring us in the face with compassion and grace and humility, splendid and simple and complex as it is. You become an expert when you realize that all evidences hinge on truth, and your understanding of them can then rightly be filtered, and there is suddenly no disagreement or conflict that cannot be properly contextually placed. From that moment on, everything you see is further testimony to the knowable, personal God. Humanists who think it possible to leave this all-encompassing insight out of an arena like politics--or, really, any portion of life--misunderstand entirely what truth must be and lead to. An encounter with truth, especially after an exhausting search for it, is transformational. If you have not been transformed, you have probably not yet understood your encounter with truth. Instead of dismissing it, you should continue looking. The proof is there; the only setback to seeing it is you yourself. But--through faith, after working through your particular evidences--you are also your own key for overcoming it. In this, God has given you a great bit of leeway and responsibility, so I hope you don't rely too heavily on the mercies, opinions, and consensus of others.
