I’m not sure how humans go about creating ideas, and therefore cannot be sure that the resulting ideas aren’t a combination of learned things. There have been people in history who did things like guess that everything is made up of tiny particles long before we could ever test the idea, but probably they got the idea from observing various forms of matter, right? Like seeing how rocks can crumble into sand and grain can be ground to flour. I don’t think they would have been able to come up with the idea in a vacuum. I think anything we’re capable of creating must be based on things which we’ve already learned about, but I don’t know that I can prove that.
