Levels of description
The same thing is true at every level and means different things.
Levels of description is Hofstadter's name for the fact that the same system can be explained truthfully in very different ways. A running computer can be described as moving electrons, switching circuits, executing code, or playing a game of chess. Each account is correct. None makes the others wrong.
Hofstadter stresses that higher levels are not just shorthand for lower ones. Knowing every electron in a chess computer would not tell you it is planning a sacrifice of the queen. Meaning often lives at a higher level and can be invisible from below. Magritte's painting of a pipe captioned as not being a pipe makes a related point: the picture and the object belong to different levels. The same is true of people, who can be explained by chemistry, biology, psychology or social context.
The pitfall is using level-switching to dodge problems. When a discussion keeps jumping from details to grand theory and back, nothing gets decided. The goal is to find the level where a useful action is possible and to stay there long enough to act.
This idea ties the deck together. Strange loops, the self, and Gödel's result all involve a system at one level referring to itself at another.
Example
You feel exhausted every afternoon. At the body level, it might be lunch or sleep. At the habit level, it might be the meeting schedule. At the meaning level, it might be work you have stopped caring about. Testing an earlier bedtime first, then the calendar, keeps you at levels where you can act.
Try it this week
For one stubborn problem this week, describe it at three levels, then choose the one where you can take a concrete step today.
From Strange Loops, Core Four (Douglas Hofstadter · 1979).
