The text explicitly states the opposite of that.

"NULL = 1" --> Unknown

Incorrect.

Question: have you ever written any tests in school?

Yeah, I’m not a programmer, but if I am following correctly, then null = true or false. That is, it still has to be true or false, and it cannot be true and false or not true and not false.

Meaning, I’m right. We might not know the answer, but it has to be true or false. It can’t be both or neither.

Ah ok....well, I haven't changed the definition of true and false....set theory as implemented in databases is probably the easiest way to understand it:

You're absolutely right. I have consciously blended Daoism and Zen. I have never been a member of a Daoist group. And all I have ever done is read Laozi and Zhuangzi. However, I had quite the mystical experience one day that lasted for more than two years. That came directly from reading Laozi. But, the only explanation I could find for what happened to me came straight out of Zen. Very perceptive on your part. Not too long ago I shifted back toward Daoism, but only the Laozi/Zhuangzi version. I couldn't care less about Internal Alchemy and all that. I studied with a Daoist priest and after two days I left because it was nothing like what I was after. It was then that I started looking at Zen.

I’ve been thinking about this, and I think what you’ve essentially done is changed the definition of true and false. That is, equivocation. Under your definition, true ≠ not false and false ≠ not true, leaving room for a third option, which isn’t possible if true = not false and false = not true.
