&gt; The territory is never observed other than through maps, and the maps are all math.<p>Be careful with words here. The universe is observed through other means than maps all the time. In fact, it is what everyone is doing all the time.<p>The universe is <i>described</i> using maths. It is also often described by neuron firing patterns in brains or less accurately using English or Russian. Just like territories are described by maps or less accurately using English or Russian.<p>&gt; But the more detailed you make the description of something, the less of a distinction there is between the description and the thing! At some point, the description must be the thing. (If it isn&#x27;t then just alter whatever is different between the two and patch the description; then repeat.)<p>That doesn&#x27;t follow. At the limit to infinity, the description is the perfect description. There is no reason to believe it becomes the thing itself.<p>The line segment representing the radius of a circle perfectly describes a circle. That does not mean a line segment is the same as a circle.
