Maps are not reality at all--they can be tyrants. I know people who are so immersed in road maps that they never see the countryside they pass through, and others, who, having traced a route, are held to it as though held by flanged wheels to rails.
―John Steinbeck, Travels with Charley
Yes, but I would alter this a bit: I think it's not that maps "are not reality at all," but that they aren't all of reality.
