there's various levels and versions of what's true, and the author of the following piece will explore those concepts for you to consider below;

If you’re one of the millions of human beings who, despite a preponderance of evidence to the contrary, still believe there is such a thing as “the truth,” you might not want to read this essay. Seriously, it can be extremely upsetting when you discover that there is no “truth” … or rather, that what we’re all conditioned to regard as “truth” from the time we are children is just the product of a technology of power, and not an empirical state of being. Humans, upon first encountering this fact, have been known to freak completely out and start jabbering about the “Word of God,” or “the immutable laws of quantum physics,” and run around burning other people at the stake or locking them up and injecting them with Thorazine. I don’t want to be responsible for anything like that, so consider this your trigger warning.

OK, now that that’s out of the way, let’s take a look at how “truth” is manufactured. It’s actually not that complicated. See, the “truth” is … well, it’s a story, essentially. It’s whatever story we are telling ourselves at any given point in history (“we” being the majority of people, those conforming to the rules of whatever system wields enough power to dictate the story it wants everyone to be telling themselves). Everyone understands this intuitively, but the majority of people pretend they don’t in order to be able to get by in the system, which punishes anyone who does not conform to its rules, or who contradicts its story. So, basically, to manufacture the truth, all you really need is (a) a story, and (b) enough power to coerce a majority of people in your society to pretend to believe it............http://www.unz.com/chopkins/manufacturing-truth/
