Archimedes and I had talked about many things over the decades. I think he now understood that I wasn’t some kind of supernatural being, just someone with more knowledge than him. In a society where very little changed from generation to generation, it was easy to think of The Way Things Are as some kind of natural state. But Archimedes had seen enough new knowledge in his lifetime to understand that when you went from not knowing something to knowing something, it changed the way you lived.
