No amount of belief will make something a fact.
--James Randi
Human brains are hard-wired to make connections and form conclusions that become beliefs. The weird thing is that we don't really get to choose what we believe; well, not so much as a conscious decision as choosing what to wear each day. Indirectly, it does seem that we can open our minds to new information, causing internal conflict which may or may not get resolved as a change in belief.
Take, for instance the 2013 case of Republican Senator Rob Portman's views on gay marriage. As a Republican, he was obligated to tow the line on defence of 'traditional' marriage. His personal views on the matter were likely in line with the party views as well. His world gets shaken up when his son reveals he is gay. Two years of cognitive dissonance and then the Senator announces that he supports gay marriage. This could have played out in a number of ways. Some people disown children that lead lives that are different than their own. Others attempt to ignore the elephant in the room and pretend that their own reality is the one true reality. But Senator Portman's stance on gay marriage changed. He said, "Ultimately, for me, it came down to the Bible's overarching themes of love and compassion and my belief that we are all children of God." The fact of the matter is that we are all humans, whether or not you believe that we are children of any god. We should treat our fellow humans with respect and allow them every right that we would like to enjoy ourselves. You know, the Golden Rule (and the Silver Rule too.)
But sometimes it is hard to see the end game because of our own blindness. What blinds us? Belief. Belief is an irrational mess of neural connections in the brain that causes a person to link some concept with the notion of truth. It is the neural equivalent of a logical identity. It does not require any proof; it just IS. We fill our brains with these beliefs with one informing and changing the next, the whole of which becomes the basis for our world view. The world view filters and influences every new concept and event that enters the brain. These new filtered thoughts then affect our world view; sometimes reinforcing it, sometimes tearing it down for realignment. But it all boils down to the fact that our brains are squishy and fuzzy when it comes to logic and rationality; these two concepts rarely have much sway when we are encountering new ideas. Mostly we believe what we believe because we believe what we believe. People with degrees in this field call this confirmation bias.
So you see, to believe is to believe; it has nothing to do with facts, logic, rational conclusions, or reality. But just because you believe something does not make it a fact.
Once I understood the concept of confirmation bias, I was able to start to see instances where my own beliefs were influencing me, causing me to reject logical or otherwise rational thought because it did not mesh with my current belief system. And then as you know it all fell apart (i.e. my religious foundations crumbled) and I had to start questioning all my beliefs to see if they were founded in reality or if they were floating, supporting themselves by the power of confirmation bias. But I am in a better place now, mentally. I don't have to juggle so many things and my shelf, the things I have questions about, is much less about god and religion and more about life, the universe, and everything. This is not to say that I have conquered confirmation bias; that is not possible. My brain is still every bit as irrational and squishy as it ever was, but now I am much more open to the idea that my belief system might be systemically wrong. Maybe now, you might say that I have to take the periodic effort to prune my belief garden, looking for un-rooted beliefs and moving them over to the unfounded idea museum where live the invisible pink unicorn, Santa Claus, fairies, and yes, all the gods.
