My earliest childhood memory is of my father going crazy when the Giants won the World Series in 1954. He started whoopin' and hollerin' and jumpin' up and down all around the living room. I started crying because he scared me to death.

So, Mexico, Brazil, they wanted their national culture to be 'blackish' - really brown, a beautiful brown blend. And finally, I discovered that in each of these societies the people at the bottom are the darkest skinned with the most African features.

My father lived to be 97 and played bridge every day up to the end, so I've got a 50 percent chance of living a long life like him.

The biggest surprise for me, without a doubt, was that the first black people who came to the United States weren't the 20 who arrived in Jamestown in 1619. All of us had been taught that. The first African came to Florida in 1513. And the huge shock is we know his name, Juan Garrido, and that he wasn't a slave. He was free!

In the old days, you lived in one neighborhood, you knew all your neighbors and your daughter married the guy next door. That was social and economic progress. That model is gone now. We also had a world order that was fraught but fairly stable.

In America there is institutional racism that we all inherit and participate in, like breathing the air in this room - and we have to become sensitive to it.

When Europeans came upon real ruined cities they refused to believe that they had been built by Africans. Here the past has been distorted and denied.
