In Part I, I discussed the fact that (at least) two kinds of distinct processes get labeled as “top-down”. The first, blueprint processes cannot produce nor grapple with complexity. The second, presented here in Part II, are consistent with the generation of complexity. These are coarse-to-fine processes.
Real-world complex systems typically have multiple scales of structure and behavior. That is, they have coarse aspects (think your skeleton and muscles which operate on a scale not too much smaller than your whole body, many pieces acting in tight coordination), and fine ones (think immune system function where very small things serve to do things like detect other small things like viruses and bacteria). Coarse things are what you can still see if you “blur the picture”, whereas the fine-grained details will be lost.
