There seems to be some confusion between knowledge and truth.

Knowledge is, quite simply, the signals we extract from the noise.

Are they true? One man's signal might be another man's noise.

One man's truth, might be another man's conspiracy theory.

Is there objective truth?

Presumably 1+1=2 is objectively true. Yet it is also elemental math.

How about when things get more complicated?

We are all subjective points of reference and the signals we extract from the noise are what resonates and synchronizes with our prior knowledge base.

The problem is that earlier knowledge base arose from less information. Which leads to a tendency to patch one's beliefs, assumptions, theories, than question or falsify them. As the say goes, "Change happens one funeral at a time."

Religion might be thought of as the childhood memories and lessons on which a culture forms, so that whole process of civilization, of learning what prior generations assumed to be true and building on it, applies to all of society and knowledge.

Though even for cultures, the occasional funeral is necessary. The paradigm doesn't just shift, it breaks.

When the old order becomes brittle and disconnected, it is like a scab of old skin, slowly peeling away. The positive feedback loops have turned negative.
