The map–territory relation—the relationship between symbol and object—is one of the lasting philosophical quandaries.
Coined by Alfred Korzybski, The map is not the territory is a related expression meaning that an abstraction derived from something, or a reaction to it, is not the thing itself, e.g., the pain from a stone falling on your foot is not the stone; one's opinion of a politician, favorable or unfavorable, is not that person; a metaphorical representation of a concept is not the concept itself; and so on. A specific abstraction or reaction does not capture all facets of its source—e.g., the pain in your foot does not convey the internal structure of the stone, you don't know everything that is going on in the life of a politician, etc.—and thus may limit an individual's understanding and cognitive abilities unless the two are distinguished.
