We've been seeing a lot of debate recently about how history should be taught. For example, some believe that the Civil War was about state rights while some argue that slavery played a large role in it. But what if we could all agree on one shared history? The past, as we know it, is a collection of billions of smaller stories that coalesce into the stories of families, communities, nations, and entire cultures. According to Tamim Ansary, narrative is the way we invent the past and the key to understanding history is understanding the stories we tell ourselves about three key areas: technology, environment, and language. With a world seemingly more connected than ever and still volatile with a constant sense of fracturing identities, Tamim contends that our shared history is a story we must invent. And the future of our species depends on our ability to develop a story we can all see ourselves in.
