 Because if that's the case, you won't know anything. I remember even when I was a kid, we were flattered by our teachers. They said, you have more information at your fingertips than Plato or Aristotle did. I thought, that's true, but we don't know anything. I know much less than Plato and Aristotle, even though I have a magical iPhone, even though I have a calculator. Yeah, but I still know much less than them because I don't really know it.
