"Blank looks, check. It's okay, you're probably using this fragment of Law correctly, you just don't know it to yourself. I should probably be playing some sort of game to make this point, but all the ones I know are literally aimed at five-year-olds and would be excruciatingly slow soooo."
"You're maintaining, in your own mind - something like the scaffolding Carissa used to reach out to her spellsilver, between my hand, and the writing on this wall. Only much less complicated than Carissa's scaffold, and also the correspondence is something represented inside you, rather than out in the air where you can see it with Detect Magic. If there's a silver in my hand, right now, you'd say the writing on the wall is true. If there's a copper in my hand, or for that matter, nothing, you'd say the writing on the wall is false. Or if you wanted to be more precise about it yet, you'd say that the meaning of the writing or the proposition the writing talks about in Taldane is false."
"When your mind maintains a correspondence of this type, it does a ton of intricate work in the background. For example..."
Keltham opens his hand, showing that in there is a copper coin, and then replaces it with a silver one.
"First you learned that the writing on the wall was false, and then, the writing suddenly turned true. How can this be? Is truth unstable? No, it's that the word 'now' in the sentence is actually a powerful word in terms of the scaffolding your mind builds. Carissa decided while she was building her scaffold to move the spellsilver a little further away, and then stretched her scaffold to reach out to it. The scaffolding of meaning between my hand and the wall-writing, as your mind maintains it, instructed by that word 'now', is something that constantly slides through time. In every moment of time, the wall-writing has a different meaning, there is a different fact-in-the-world that makes it be true or false, because it is talking about the contents of my hand in that moment of time, according to the scaffolding your mind is maintaining inside itself."
"To extent that meaning is fixed, it always has fixed truth or falsity; to the extent it seems like truth or falsity is unstable, we can always deduce that it's the meaning that's really unstable, that something is wrong in the scaffolding we build in our minds, not that reality itself has anything being simultaneously so and not-so."
