> But I think a good summary is that emergence happens when relations between things on a finer level of analysis become the things themselves on a coarser, higher level AND that these new things also have rich and complex interactions among them, making the levels roughly equally interesting, complicated and useful. Overall the bottom level is "enough" in theory but rising up the levels allows us to gain orders of magnitude more "practicality". Hofstadter discusses this in his book I Am a Strange Loop: there's a line that's something like "sometimes the bottom level - despite being entirely responsible for the effect in question - is nonetheless totally irrelevant to it"
