I agree. Hence "white lie." After all, a white lie is a good lie, a justified "lie."

But, another definition, the stuff that is what it is whether or not anyone agrees on it or even knows about it, wouldn't involve consensus at all.
But does this stuff exists except as an abstraction in the human mind? This reminds me of Kant's noumena, which is a great and useful concept but has huge logical difficulties. I think Hegel was an improvement on these difficulties. The real is rational. We say there is a world beyond our opinions, and yet this itself is one more opinion.

It's important to remember the axioms you're working within.
I agree. I also think that we operate on all sorts of half-conscious axioms. Prejudices. And some of them are pragmatically justified. For instance, causality is not
logically justified. But it is
psychologically justified. Why should the future resemble the past? Because it always has?

He could have seen a real alien spacecraft. Only a fool would say that was 100% impossible. All we can say by way of supporting the conclusion he's crazy is that he does a lot of crazy things, and one of them is claim he saw an alien spacecraft. People like to jump to conclusions, especially when they don't have much information.
I agree. But perhaps you will agree that humans have certain attitude about ghosts and UFO's that aren't exactly logical. I personally don't want to believe in ghosts. I confess my desire for a more explainable predictable reality. I sympathize with finitism. I don't think we can really compute (mentally) infinity, although we
do have useful if vague concept of such.
And yes, we do jump to conclusions. Sometimes it turns out to be a scientific breakthrough. Sometimes one has a lucky hunch. But mostly one gets a stubbed toe.

I don't get what that means.
If we negate the concept of absolute truth, and say that truth is a useful lie, then the concept of "lie" is changed. Just as if we said there was no more black and white but only shades of gray. It's a move from the digital to the analog.

Whatever works. Has your own understanding of the statement evolved over time?
Well, I feel that we have truth enough to use the word in its normal sense. It's not that I no longer see how consensual truth is, but just that I'm much more interested in things like computer science and mathematics lately. And this is because an algorithm is a precise machine made almost of pure thought. I think that thinking is largely metaphorical, and that I fairly thoroughly investigated the issue and expressed my opinions on the matter. Basically I moved on to an new area of investigation. If metaphor is analog (analogy), then mathematics is largely (but not completely) discrete. At least the rational numbers are. Actually mathematics is heaving with the tension between the discrete and the continuous.
I love transcendental philosophy. I'm most interested in thinking about thinking, the essence of essence, etc. I want the root. I want to ur-science. I'll stop there.
