"A map is not the territory it represents, but if correct, it has a similar structure to the territory, which accounts for its usefulness."
[Alford Korzybski, 1958]

I came across this quote when writing a seminar thesis on systems theory. Can't help to be intrigued by it, just pondering in how many ways this could be a valid statement. Maybe for models of things, personal world views, experience, all kinds of logical abstractions..
