What if we assumed that truth can only be judged according to time spans?
For example, a particular man may gather less truth than a civilization. A civilization has less truth potential than a species. So on until we run out of categories, or reach tautology/vagueness.
This would explain the awe of one in the forest, the wisdom of the elders, why this site keeps returning to race > society.
Perhaps we could tongue-in-cheek create a truth ordinal system denoting in what frames of reference particular truths hold sway. This way we can acknowlege the perspective of others, but disagree not on facts, but in application. For example, we may argue that genetic selection of all breeding human pairs is ideal for humanity. We can agree or disagree if we designate our ordinal positions, whether in the individual/family/civilization/special/universal sphere.
Assign a truth value of True, False or Neutral. This can be assumed to be Desireable, Undesirable or Neutral for you Buddhist German Idealists out there.
Human genetic pairing should be done regard only to scientific principles, as currently best understood.
I love putting glass in my poo spigot.
We should treat people as individuals in this modern 2010+ era, ignoring genetic tendencies. Everybody should be equal in some way.
