It's funny. The ancient iron-smiths. They devised dozens of techniques for making iron harder and tougher. But they didn't know "how it works". But now we know how it works. That is to say, we have a nice body of thought that describes what we observe going on there. Good thoughts. Useful thoughts. But how does that work, with thoughts describing observations? I dunno. Maybe we're like the ancient iron-smiths, except with thoughts. Thought smiths.
