'The map is real...'

Suppose you have a city map. It’s definitely useful. Without it, you might never reach your goal. Is the map a perfect rendering of the city? No. There is no such thing as a two-dimensional, black-and-white city filled with perfectly straight paths and neat angles. But the city itself is real, the map is real, the information in it is mostly valid if simplified, and so the map is unquestionably of practical use. Knowing all this, you probably won’t suffer an existential crisis over the reality of the city or dismiss the contents or the existence of the map as an illusion. The truth is much simpler: your model of the city is helpful but not perfectly accurate.
