A better one would be with a creature that is drawn on paper. If it could live, it would live entirely on the paper, on its surface. Now imagine there was a mountain on the paper. If the creature made a circle around the mountain and measured the enclosed area, this wouldn’t help it understand what it had in front of it. There would be much more paper than, according to its reason, could fit in the circle. For this creature it would be a miracle.
