Previously I had put this three-split at the level of “principles” but as I got up this morning I remembered that the way I’m doing it “principles” ARE the domain and once I switched terms to domain, then it is all much neater and cleaner.
Hopefully this will allow the next quick graphic to be better and cleaner.
I’m basing it on what’s used in sciences:
philosophy of science
but I’ve noticed it’s used in other fields too. So I figure maybe it can be made a general rule.
