Damn, Paul, you nailed it! You are the first person to offer such a rich analysis, so I'm very grateful and appreciative. Respect!

Here are a few off-the-cuff notes, pending a deeper re-read and thought.

Yes, the atomistic aspect is crucial. As is the organic aspect, that one's test can be entirely emotional. There's no standard a test has to meet to "qualify" as a test.

If there was only one person in the world, the only hard reason to examine truth units is to survive be fulfilled in life. Disagreement is basically a social issue. People have to work together.

I think truth units embraces pragmatism because its benefits are self-evident as a means to an end.

The basic raison-d'etre for truth units is to avoid people going crazy over doubt. It does so through an accessible system of accountability.

Looking forward to more dialogue. Thank you for reading!
