Define the boundary first
Before judging a part, identify the system, its environment and the level at which the question is being asked.
WORLDVIEW / PRINCIPLES
Rules that are still earning their place.
These principles are versioned working judgments. They may change when stronger evidence or repeated practice shows a better model.
Separate fact, model and wish
A useful system keeps evidence, inference and intended direction distinguishable.
Preserve the upper whole
Local continuation or expansion is not justified when it destroys the larger system that makes it possible.
