Well to what degree is truth, itself, a quality that is particular to a given psyche, with a given set of experiences and a given set of values? We can make the case the universal truths exist, but in a somewhat pre-articulated and fuzzy way.
But then again, if the system didn't pit at least some of its components against the average, the average itself wouldn't be as refined. That is, if some universal truth appeared clearly to everyone, the system arguably would be ineffectively tempering the collective refinement of truth.
Arguably we see this in politics: if we consider the entire array of political viewpoints as being orchestrated by some preconscious, preindividual function, then dissent among viewpoints would arguably function as some kind of combustion to concatenate dialogues that humans are only partially conscious of.
In this case, the function would best function if some of the viewpoints adamantly opposed others.
Truth is anisotropic, perhaps, appearing differently from different perspectives, different angles. The angle would be the viewpoint, the particular value system, and the whole set of possible angles would be the ideological matrix established by preconscious, preindividual, but perhaps nonetheless physical forces.
And within such a space, values become unambivalent and take positions, and each position makes an implicit negation of some set of other possible positions, an infinite set.
