I read several hundred pages of ‘‘Little House on the Prairie’’ to my 5-year-old son one day when he was home sick from school. Near the end of the book, when the Ingalls family is reckoning with the fact that they built their little house illegally on Indian Territory, and just after an alliance between tribes has been broken by a disagreement over whether or not to attack the settlers, Laura watches the Osage abandoning their annual buffalo hunt and leaving Kansas. Her family will leave, too. At this point, my son asked me to stop reading. ‘‘Is it too sad?’’ I asked. ‘‘No,’’ he said, ‘‘I just don’t need to know any more.’’ After a few moments of silence, he added, ‘‘I wish I was French.’’

The Indians in ‘‘Little House’’ are French-speaking, so I understood that my son was saying he wanted to be an Indian. ‘‘I wish all that didn’t happen,’’ he said. And then: ‘‘But I want to stay here, I love this place. I don’t want to leave.’’ He began to cry, and I realized that when I told him ‘‘Little House’’ was about the place where we live, meaning the Midwest, he thought I meant it was about the town where we live and the house we had just bought. Our house is not that little house, but we do live on the wrong side of what used to be an Indian boundary negotiated by a treaty that was undone after the 1830 Indian Removal Act. We live in Evanston, Ill., named after John Evans, who founded the university where I teach and defended the Sand Creek massacre as necessary to the settling of the West. What my son was expressing — that he wants the comfort of what he has but that he is uncomfortable with how he came to have it — is one conundrum of whiteness.

‘‘Tell me again about the liar who lied about a lie,’’ my son said recently. It took me a moment to register that he meant Rachel Dolezal. He had heard me talking about her with Noel Ignatiev, author of ‘‘How the Irish Became White.’’ I had said: ‘‘She might be a liar, but she’s a liar who lied about a lie. The original fraud was not hers.’’ Because I was talking to Noel, who sent me to James Baldwin’s essay ‘‘On Being White ... and Other Lies’’ when I was in college, I didn’t have to clarify that the lie I was referring to was the idea that there is any such thing as a Caucasian race. Dolezal’s parents had insisted to reporters that she was ‘‘Caucasian’’ by birth, though she is not from the Caucasus region, which includes contemporary Armenia, Georgia and Azerbaijan. Outside that context, the word ‘‘Caucasian’’ is a flimsy and fairly meaningless product of the 18th-century pseudoscience that helped invent a white race.

Whiteness is not a kinship or a culture. White people are no more closely related to one another, genetically, than we are to black people. American definitions of race allow for a white woman to give birth to black children, which should serve as a reminder that white people are not a family. What binds us is that we share a system of social advantages that can be traced back to the advent of slavery in the colonies that became the United States. ‘‘There is, in fact, no white community,’’ as Baldwin writes. Whiteness is not who you are. Which is why it is entirely possible to despise whiteness without disliking yourself.
