202402241823 Boundaries don't exist in the real world
#newThere are no separate systems. The world is a continuum. Where to draw a boundary around a system depends on the purpose of the discussion — the questions we want to ask.1
When you draw boundaries too narrowly, the system surprises you because it doesn't sufficiently account for the reality of the situation. Conversely, when you draw boundaries too broadly, you fail to find something sufficiently descriptive and useful for reasoning about a system. The lesson here is that boundaries are a useful fabrication whose delineation amounts to an art rather than a science.1
