Celebrated individuals do shape history, but so do the rest of us. And while it's true that many historical forces – malaria, meteors from space – aren't human, it's also true that every human is a historical force. You are changing the world every day, and it is our hope that by looking at the history that was made before us, we can see our own crucial decisions in a broader context. And I believe that context can help us make better choices and better changes. Thanks for watching. But there's no need to despair, Crash Course fans. I'll see you next week for the beginning of our mini-series on literature.
