My father, if anything, first and last, was a man of words. He loved stories; he didn't live for stories, exactly, but I think he lived through stories. I think, like many writers, he loved stories about things he had experienced as much as, if not more than, he loved the experiences themselves.

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.

I think that is what we do by preserving and telling our stories. If you don't tell your stories, other people will tell their story about you. It's important that we nurture and protect these memories. Things change. Existence means change. So, the kind of precious memories about being black for my generation won't exist for my kids' and grandkids' generations unless we preserve them through fiction, through film, through comic books, and every other form of media we can possibly utilize to perpetuate the story of the great African-American people.

You can find virtually everybody black back as far as the 1870 census. Why 1870? That's when the ex-slaves first have surnames. But if you find your great-great-grandfather in 1870 and it says he's 50, that means he was born in 1820 and you're back to 1820 already. For an American that's pretty damned good, you know?

My goal is to get everybody in America to do their family tree.

I would like to do a series about sequencing the human genome, and also analyze more human diversity among other ethnic groups - a 'Faces of America 2.'

Conspiracy theories are an irresistible labor-saving device in the face of complexity.
