Truth....where are you?

Just a rambling thought.........
How does one transcend the cyclical see-saw (wrap your mind around that Mobius!) of reactionary, revisionist history to get to the truth?
I grew up in the seventies, learning about the great "explorers" and their glorious "discoveries" without ever being exposed to the ugly side of those adventures. It never occurred to us fourth graders that imperialism and colonialism had any downsides. Hell, a game of "cowboys and indians" was strangely detached from the violent reality that was still fresh in the minds of some elders. That was just the way it was. My sister and I grew up in an ethnically diverse neighborhood and an equally diverse school system in Rochester, New York. Yet, we were all exposed to the same sterile, happy, white history that was portrayed in the textbooks of the day.
Strange days, those were.
By the mid-eighties, we were in high school and a reactionary movement broke out, revising the textbooks and curriculum to reflect the pain and suffering of generations of indigenous americans and the slaves torn from their respective countries.
However, this phenomenon swung history to the other side of the bias scales; going so far as to create new mythologies surrounding origins. Look at the five-percenters, for example. A n extreme reaction to the Eurocentric bias of history is to be expected, but does not necessarily speak to truth. Perhaps history is not capable of objectivity.
