For me it’s not that this is new but it’s seeing it from a new perspective with new goals in mind that changes things. I have a principle:
domains can be described as domains and tools in a wilderness,
where a wilderness and a tool are also domains and many domains can be described as having
a) principles (rules / laws / guidelines / branch of knowledge / ideal forms / nomenclature) and enforcing the principles (morality, correctness to stated principle) that define the extant of a domain (wall, level, shape, boundary, outline)
b) Applied principles (heuristics, ad-hoc, real-world, messy, attempts to apply principles that may work or not, cases (case studies)),
c) Philosophy of (why is it like that, questioning validity of principles, offering alternative to principles)
Why? I got inspired by a definition of a “tool” that I liked.
