There's a lot of work to be in the theory of emergence. We'll be talking about it in upcoming podcasts. The fact that we can cheat by seeing the higher levels immediately, or in soust, using our eyes, means, on the one hand, we can talk about different levels without understanding emergence very well. And as a result, the emergent levels can involve concepts and vocabularies that are entirely different from the concepts and Vocabularies at lower levels. That's even a little bit true even for liquids, right?
