I talk a little about this subject in my own essay. I split it up 3 ways. I know some won't agree, but that's okay. Hopefully I can explain it here in a way that makes sense. If not, then blame the author (me).
There is Absolute Truth: The way it is, no matter what we think or do. This is unobtainable to us. There are too many layers of abstraction between our awareness and our reality.
There is Evidential Truth: The way it probably is given the evidence and the most objective reasoning on that evidence the human intellect will allow. Objectivity requires us to be brutal with our worldview--we must be willing to set it aside if changing evidence denounces our current view of things. That means the Evidential Truth is always in motion (always changing) because we must force ourselves to change as new evidence keeps rolling in.
And there is Personal Truth: The way it is when we take the evidence and try to fit it into our preconceived ideas about the world. As far as I can tell, humans are probably wired to think this way by default. We tend to form an opinion of how things work early in life that seems functional and we tend to stick with that unless something forces us to change. Any new evidence that can't be made to fit into that worldview may even get tossed aside and rejected, when it should really (in my opinion) work the other way around.
Anyway, hope this gives you ideas...or even ones worthy of disagreeing with. Both the Evidential and the Personal have their limits. Both have the potential of creating false certainty about the world around us. I called all 3 of these "truths," but really the last two should probably be called truisms. Only the Absolute Truth is really, totally true. But the others seem to be true to us when we use them in figuring out our world.
