Does history repeat itself? Not really, but that's not the reason it's worth studying: Our past is nothing more or less than the collective record of our species' achievements and failures, and it contains a variety of lessons, few of them easy and straightforward. In this episode, we explore how history helps us in the present, and how it doesn't. Patrick has a brand-new history show! It’s called Past Lives, and every episode explores the life of a real person who lived in the past.
