As I see it: There is one absolute truth, it is a large set of facts that is evolving as time elapses; but there are different pictures of it, from all different observers. Many visions of what is called "truths" though, are merely constructs of the "non-observer's" minds, have no relation to the facts out there. added:
To illustrate, viewers might agree that they see a rainbow. but each sees a different set of sun rays reflected back from water droplets defined by precise angles. the sun, its radiation the rain all are fact, therefore truth, so are the individual observers, their position, their makeup,( cosmic, not cosmetic). truth is more beautiful than the facts.
