"To state it precisely, some observers may have guessed the unnecessary truth that all triangles are red, observing the redness after the delay. They may have separately guessed the unnecessary truth that all red things are large, after paying to measure some red things. Maybe they've never measured any of the red things that were triangles! we can suppose for the sake of clarity. Then the necessary truth, 'Q is true in all worlds where Z and H is true', can allow them to guess the unnecessary truth 'All triangles are large', which follows deductively from other things they've guessed. And even if they've never measured the size of a single triangle before, they can guess - though not know for certain - that every triangle they've seen was large, and that the next triangle they see will be large. If it's the kind of knowledge that matters, but not enough that you need to be very sure of it, they could use that guess in place of paying a silver piece to measure it."
"Of course, it isn't a necessary truth that the observers are capable of figuring this all out - that they can operate the necessity, 'Z and H yield Q'. We could draw an illusion of a world where the observers totally fail to figure that out. It would still be true across all planes and all illusions that could ever be drawn in full detail, but the people in that illusion wouldn't know it."
"It isn't necessary that entities successfully operate universal necessities in order to correctly produce new guesses from old guesses, which means that some entities do better or worse at this than others. This is true when considering all possible worlds as a whole, and also happens to be true within my homeworld, and almost certainly this one."
"So now we shall turn to the question: suppose you were constructing a new entity from scratch. How would you go about embedding in them an internal reflection of the interuniversal Law, the ability to operate necessary truths correctly... No, sorry, that's probably too much of a leap to ask in one go. Strike that, restart. Suppose you were comparing two entities: how would you say that one was doing better or worse than the other at being Lawful in this exact sense?"
