"There is an ancient saying that something lives only as long as the last person who remembers it. My people have come to trust memory over history. Memory, like fire, is radiant and immutable; while history only serves those who seek to control it, those who would douse the flame of memory in order to put out the dangerous fire of truth. Beware these men, for they are dangerous and unwise. Their false history is written in the blood of those who might remember and of those who seek the truth." - Navajo saying
This saying really resonates with me. I taught my children that ANY subject that has sides that people can take and argue over is not a fact, but a theory. That statement gets me into a lot of hot water with most people. Especially people who don't realize that so many of the things that they take for granted as fact are, in actuality, theories. I hold to it, though. It reminds me to be curious, to always keep learning, and to keep an open mind. Most people don't realize that there are major discrepancies between what is read, what is said, and what is experienced from person to person.
Why is it so hard for us to see and accept that the "facts" are so frequently not true for everyone and that that means that the facts are not facts but, simply, something that is true for many people much of the time rather than true for all people all of the time? Heck, there are some "facts" out there that are downright false for most people most of the time, some that are false that many people don't even recognize as false because it's become such an ingrained belief as "fact". The saddest for me, the "facts" you learned that you never took the time to question.
