Something you see often enough in science fiction (putting aside whether Kindred actually is science fiction, or fantasy, or whatever) is time travel and its attendant paradox. Actually there are a number of flavors of temporal paradox, but the one I’m thinking of is the one in which, when going back in time, you might change things that would change your present and thus potentially impact you and your ability to go back in time to begin with.
If Dana goes back in time and changes enough about Rufus’s life, he might not turn out to be her progenitor, which in turn would prevent her from going back in time to make those changes. This is familiar territory for Marty McFly.
On page 51, Butler brings up another paradox as Dana and Kevin talk about her return from her second visit to Rufus. Recall that their theory is that, as a threat of Rufus’s death is what calls her to him, the threat of imminent death to her is what brings her back home. Dana says:
For instance, I would have used your knife against that patroller last night if I’d had it. I would have killed him. That would have ended the immediate danger to me and I probably wouldn’t have come home.
In short, in order to remain alive in order to attempt to return home, she may have to do something that will prevent the thing that enables her to return home. It’s a paradox.
A little later, on page 68 in my edition, Dana reflects on the man Rufus is likely to become:
As I hurried up the steps and into the house, I thought of Rufus and his father, of Rufus becoming his father. It would happen some day in at least one way. Someday Rufus would own the plantation. Someday, he would be the slaveholder, responsible in his own right for what happened to the people who lived in those half-hidden cabins. The boy was literally growing up as I watched — growing up because I watched and because I helped to keep him safe. I was the worst possible guardian for him — a black to watch over him in a society that considered blacks subhuman, a woman to watch over him in a society that considered women perennial children. I would have all I could do to look after myself. But I would help him as best I could. And I would try to keep friendship with him, maybe plant a few ideas in his mind that would help both me and the people who would be his slaves in the years to come. I might even be making things easier for Alice.
It’s horrifying, isn’t it? Dana not only must fight to stay free and alive in an environment inimical to that imperative but also bears the burden of trying to make things better for those who will both follow her (as time traveler) and produce her (as ancestors). She must be extraordinarily careful lest she change the past in a way that negates her future present (this stuff is hard to write about intelligibly). And she must grapple with how difficult it is to be the guardian of a child raised in a society that enslaves Black people and infantilizes women. It’s sort of an ethical double-bind wrapped within a temporal paradox.
I read this passage after listening to an episode of a podcast titled Hear to Slay, by Roxane Gay and Tressie McMillan Cottom. They label it “the Black feminist podcast of your dreams,” and it is very well worth listening to — fun, incisive, serious, and informative all at once. I’m a few episodes behind and today was listening to the February 1 episode entitled “It’s Our Country Too,” in which they chat with country music artist Rissi Palmer about country music and Black country music. They talk some about why Black women often do hard, extra labor, and in short, it’s so that others who follow can have it easier. Palmer came back to country music on her own terms in spite of getting screwed by the industry. At about the 30-minute mark of the episode, she says “I keep fighting, and I keep caring about it, because, while I’ve figured out a way to have a career and a life and be happy outside of it, people that look like me, and anybody else, if that’s what they want, they should be able to have it.” This seems to me to be directly related to what Dana’s doing in Kindred. Of course she is trying to survive, but she thinks too (and foremost) of Rufus’s safety and upbringing, of those generations between Rufus and the Dana of 1976, and of her husband Kevin (a white man). She is serving, to borrow a relevant phrase from Hurston, as the mule of the world, carrying the burdens of others.
Like many people in marginalized groups, Butler is carrying the burden herself, describing awful, painful details of enslavement in order to tell a story about the past and the legacy of being Black in America. Activists and other Black people who speak on social justice take on this burden not to improve their situations but to improve the situations of current and future others. This too strikes me as a sort of near-paradox: In order to put a stop to the horror and the damage it causes, people are made to immerse themselves in the horror and suffer the damage it causes.
