Contemporary biologists are not agreed on the question of whether there are any human races, despite the widespread scientific consensus on the underlying genetics. For most purposes, however, we can reasonably treat this issue as terminological. What most people in most cultures ordinarily believe about the significance of “racial” difference is quite remote, I think, from what the biologists are agreed on. Every reputable biologist will agree that human genetic variability between the populations of Africa or Europe or Asia is (...) not much greater than that within those populations; though how much greater depends, in part, on the measure of genetic variability the biologist chooses. If biologists want to make interracial difference seem relatively large, they can say that “the proportion of genic variation attributable to racial differences is … 9 – 11%.”1 If they want to make it seem small, they can say that, for two people who are both Caucasoid, the chances of difference in genetic constitution at one site on a given chromosome are currently estimated at about 14.3 percent, while for any two people taken at random from the human population, they are estimated at about 14.8 percent. The statistical facts about the distribution of variant characteristics in human populations and subpopulations are the same, whichever way the matter is expressed. Apart from the visible morphological characteristics of skin, hair, and bone, by which we are inclined to assign people to the broadest racial categories—black, white, yellow—there are few genetic characteristics to be found in the population of England that are not found in similar proportions in Zaire or in China; and few too which are found in Zaire but not in similar proportions in China or in England. All this, I repeat, is part of the consensus . A more familiar part of the consensus is that the differences between peoples in language, moral affections, aesthetic attitudes, or political ideology—those differences which most deeply affect us in our dealings with each other—are not biologically determined to any significant degree.[…]In this essay, I want to discuss the way in which W. E. B. Du Bois—who called his life story the “autobiography of a race concept”—came gradually, though never completely, to assimilate the unbiological nature of races. I have made these few prefatory remarks partly because it is my experience that the biological evidence about race is not sufficiently known and appreciated but also because they are important in discussing Du Bois. Throughout his life, Du Bois was concerned not just with the meaning of race but with the truth about it. We are more inclined at present, however, not to express our understanding of the intellectual development of people and cultures as a movement toward the truth; I shall sketch some of the reasons for this at the end of the essay. I will begin, therefore, by saying what I think the rough truth is about race, because, against the stream, I am disposed to argue that this struggle toward the truth is exactly what we find in the life of Du Bois, who can claim, in my view, to have thought longer, more engagedly, and more publicly about race than any other social theorist of our century. 1.
