Replying to discussion of Invisible Pink Unicorn
Yes, it is possible for the majority of the human race to be wrong, but it is somewhat more difficult for them to be wrong about whether or not they experienced something.
It would be somewhat more difficult to maintain faith without ever experiencing the divine, but I would argue it's still possible to rationally come to the conclusion God exists without direct evidence.
I offer the following analogy:
My wife has a friend named Julia. I have never met Julia, but I have no doubt that she exists. If I ask different people about her I will get different responses, including "who?" from people who haven't heard of her. It is unlikely that any two people who have met Julia would give exactly the same account. It is always possible that I will meet Julia at some point in the future, but there is no way to guarantee that I will. Even if I knocked on her door, she might not be home.
However, if I do meet Julia, there can only be 2 possible truths to the situation 1) Julia is real 2) I'm schizophrenic. Given that I can also conclude that if I haven't met her but my wife says she has that either 1) Julia is real 2) my wife is crazy or 3) my wife is lying to me.
Considering the possibility that someone is crazy is generally not useful unless there is substantial supporting evidence, outside of the initial claim. The possibility of a liar is is quite possible in the case of an individual, but if you have a large population that all says the same thing this possibility becomes much more remote, almost to the point of non-existence.
Whether an individual exists, or a certain trivia question is true is, of course, wholly different than the "big questions". The truth of Julia's existence is not going to weigh in on how you should act (morals) or how you conceive of the universe working. If it's your wife's imaginary friend and you find out, of course, you would change how you would act with your wife and be emotionally shocked, but if your local grocery clerk talked about imaginary Julia you may just humor her so you can be on your way. Whether or not Liverpool is the capitol of the UK will have no bearing on how I live my life, just on where I may get my facts from.
Religion on the other hand dictates one's morals and one's perspective on life. Accepting religious explanations at face value will narrow one's understanding of reality and keep an individual under the control of religious leaders.
Of course, this may not apply to you or anyone reading. A lot of people draw a line between religion and spirituality and don't base their beliefs on tradition or culture.
My point is teaching someone (especially a child) that an invisible pink unicorn exists because the vast majority of society has the same beliefs is not the right thing to do. The "big questions" deserve more critical thought.
Thus I am left with 2 possibilities concerning God 1) God exists, at least in some form or 2) half the human race has the same mental illness. Number 2 is actually possible, though not very reassuring, generally I fall back on other arguments when discussing this possibility.
Whether its comforting or not, the human race has had a series of mental illnesses-war, slavery, tyrannical governments, genocide, child abuse, addiction, starvation, etc. Luckily, with technology, reason, and discourse most of us don't have to live with those illnesses. I consider all those disasters as resulting from delusions, so I don't consider it a far stretch for humanity to still be lost in other mental traps, myself not excluded.
