"Then, from Lawful thinking, comes the skill to uncover the Laws of the outer world. I am trying to apply such of that Law as I merely remember to the problem of dropping the cost of spellsilver production by a factor of 10. But my memory is very incomplete, and in some cases will be wrong, and there are important things that I never learned at all."
"I have some ideas about how to cheaply produce huge quantities of high-purity sulfurious acid, as they call 'sulfuric acid' around here, because it's a precursor to an incredibly large number of industrial processes. Civilization went through hundreds of millions of tons of the stuff every year. That's not an exaggeration, our actual production figure was 300 million tons, if I'm recalling it correctly, or a third of a ton per year per person. So there are stories out of dath ilan in which somebody like me ends up on an alien planet somehow and then has to figure out how to produce a lot of acid, basically the specific situation I am now in, and the stories go into detail on exactly how to do that, even if you don't have any magic."
"Even so, I don't remember a lot of key points there. And when it comes to other things, what I have are not blueprints but hints. Hints can be worth an awful lot, in this sort of business, compared to striking out completely blindly. Hints can save you incredible amounts of time if you could've otherwise gotten to the same place all on your own without the hint."
"Somebody who would never get the answer on their own, is probably not going to get it even with the hint, not in any reasonable amount of time."
"So you need to learn to be the sorts of people who could wield Law-inspired and Law-reshaped thought and no small amount of actual numerical calculation, to experiment and discover the Law of the world. And then further wield Law-inspired thought to apply the Law of the world to engineer new processes, new technology. Processes that will use magic for a shortcut, where possible and economically feasible."
