The Beginning of Infinity

I love what David Deutsch has to say about progress and his confidence and optimism. He starts, who was supposed to be, rejects, but he starts with Plato. And there's nothing inside his own mind until he uses his senses to gain facts out there. So the beginning point in epistemology, the begin point in thinking, must be what's out there. There's a tool with no content, but the content comes from outside. The content, you're not born with content. You're born with the tool.
