[H]istory is an effective tool to change a country by embracing the truth of a painful past.

History often teaches us to embrace ambiguity, to understand there aren’t simple answers to complex questions, and Americans tend to like simple answers to complex questions. So the challenge is to use history to help the public feel comfortable with nuance and complexity.

Removing statues in many ways is about finding a more accurate history, a history that is more keeping with the best scholarship that we have out there. So for me, it is about making sure we don’t forget what those statues symbolize. It’s about pruning them, removing some, contextualizing others and recognizing that there is nothing wrong with a country recognizing that its identity is evolving over time. And as this identity evolves, so does what it remembers. So it does what it celebrates.

He then said words that have shaped my career: if you are a historian then your job better be to help people remember not just what they want to remember, but what they need to remember.

As I conceptualized the National Museum of African American History and Culture, I knew it had to fulfill Mamie Mobley's charge: to be a place that carried the burden of history and the weight of memory, regardless of how painful or difficult it was. At the core of the museum, therefore, would be a commitment to remember.
