You have a diasporic black world, and the only way to put it back together again is symbolic. It's like Humpty Dumpty. Whoever could edit the 'Encyclopedia Africana' would provide symbolic order to the fragments created over the past 500 years. That is a major contribution.

Without doubt, President [Barack] Obama is a great historical figure.

I think that the roots of racism have always been economic, and I think people are desperate and scared. And when you're desperate and scared you scapegoat people. It exacerbates latent tendencies toward - well, toward racism or homophobia or anti-Semitism.

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.'

In a one-hour documentary, you can tell maybe ten stories. That's how the documentary is structured. I wrote to forty of the greatest historians of both African and African-American history, and hired them as consultants. I had them submit what they thought were the indispensable stories, the ones they felt this series absolutely had to include.

You can say I had a severe case of 'Roots' envy. I wanted to be like Alex Haley, and I wanted to be able to... do my family tree back to the slave ship and then reverse the Middle Passage, as I like to put it, and find the tribe or ethnic group that I was from in Africa.

I want to get into the educational DNA of American culture. I want 10 percent of the common culture, more or less, to be black.
