It's very lonely being a prominent black intellectual at an institution where you're the only prominent black intellectual. That was the model that was followed in the late 60s when black studies started. You'd get one here and one there and one here, like Johnny Appleseed.

Thousand years ago, we all descended from Africans who left the continent. Those ancestors, we will never know their name. We can go back 200 or 300 years and actually populate your family tree with real people who had names and documents. They had customs, characteristics that, unbeknownst to you, you have inherited. Almost through osmosis it has been passed down to you.

There are just so many stories that are buried on family trees.

I want to be remembered as someone who tried to bring the story of our ancestors to the broadest possible audience. I want to be remembered as a man who loved his race.

Our society is driven today by so much ethnic discord. We have Black Lives Matter, which I praise and celebrate. We have the demagogues stereotyping Muslims and resurrecting racist stereotypes they used to visit on us. The larger goal is to show that we are all the same, we all come from Africa, and we all have the same larger family tree. It's about the fundamental unity of the human community.

I find that people today tend to use them interchangeably. I use African-American, because I teach African Studies as well as African-American Studies, so it's easy, neat and convenient. But sometimes, when you're in a barber shop, somebody'll say, "Did you see what that Negro did?" A lot of people slip in and out of different terms effortlessly, and I don't think the thought police should be on patrol.

Diversity doesn't mean black and white only.
