Map-Territory Relation

The map-territory relation is the foundational epistemological principle that a representation of reality is not identical to the reality it represents. The concept was introduced by Alfred Korzybski in his 1933 book Science and Sanity and has since become central to general semantics, cybernetics, and systems theory.

The principle is often summarized as "the map is not the territory," but this is a simplification. Korzybski's fuller claim was that a map cannot represent all of the territory, and that the map is not the territory in the sense that the representation is a different kind of thing from the represented. The map is a structure in a medium; the territory is a structure in the world.

In systems theory, the map-territory relation becomes the model-territory relationship: a formalization of the same principle for engineered and computational systems. The distinction between a map and a territory is not merely philosophical; it is operational. A controller that confuses its model with the physical system is a controller that will fail when the system deviates.

The danger of the map-territory relation is not that people forget it. It is that people believe they have already taken it into account, when they have only moved the confusion to a higher level of abstraction.
