And There Was Light, and It Was Good?
There hardly seems a place on earth untouched by social and political hierarchies linked to skin color, which rank the world's rainbow of skin tones according to two shades, light and dark. That distinction is the foundation of the current notion of race.

As how to define racism, much less what to do about it, roils the delegates to the United Nations' World Conference Against Racism in Durban, South Africa, it might be wise to remember that the importance of skin color is largely a modern invention.

Certainly, slavery and many other oppressive forms of hierarchy have existed throughout human history, as have differences in skin color. But the idea that the two have a cause-and-effect relationship is relatively new, with its genesis, many academics say, in the trans-Atlantic slave trade and the colonialism that emerged with it.

ANOTHER way of thinking about skin color is to ask: When did Europeans start thinking of themselves as white?

"There was no whiteness prior to the 17th century," said Manning Marable, director of the Institute for Research in African-American Studies at Columbia University. "Whiteness is the negation of something else. The something else are Africans who are described by Europeans not by their religion or nationality but by the color of their skin. And nowhere in Africa did Africans call themselves `black.' "

The word race was used for the first time in a modern sense, it is widely believed, in a 17th-century French travelogue, Dr. Brace said.
