represents a part of a "disfigured heritage." Scholars have also noted the importance of Kevin's forehead scar, with Diana R. Paulin arguing that it symbolizes Kevin's changing understanding of racial realities, which constitute "a painful and intellectual experience." Race as social construct The construction of the concept of "race" and its connections to slavery are central themes in Butler's novel. Mark Bould and Sherryl Vint place Kindred as a key science fiction literary text of the 1960s and 1970s black consciousness period, noting that Butler uses the time travel trope to underscore the perpetuation of past racial discrimination into the present and, perhaps, the future of America. The lesson of Dana's trips to the past, then, is that "we cannot escape or repress our racist history but instead must confront it and thereby reduce its power to pull us back, unthinkingly, to earlier modes of consciousness and interaction." The novel's focus on how the system of slavery shapes its central characters dramatizes society's power to construct raced identities. The reader witnesses the development of Rufus from a relatively decent boy allied to Dana to a "complete racist" who attempts to rape her as an adult. Similarly, Dana and Kevin's prolonged stay in the past reframes their modern attitudes. Butler's depiction of her principal character as an independent, self-possessed, educated African-American woman defies slavery's racist and sexist objectification of black people and women. Kindred also challenges the fixity of "race" through the interracial relationships that form its emotional core. Dana's kinship to Rufus disproves America's erroneous concepts of racial purity. It also represents the "inseparability" of whites and blacks in America. The negative reactions of characters in the past and the present to Dana and Kevin's interracial relationship highlight the continuing hostility of both white and black communities to interracial mixing. At the same time, the relationship of Dana and Kevin extends the concept of "community" from people related by ethnicity to people related by shared experience. In these new communities, whites and black people may acknowledge their common racist past and learn to live together. The depiction of Dana's white husband, Kevin, also serves to examine the concept of racial and gender privilege. In the present, Kevin seems unconscious of the benefits he derives from his skin color ,as well as of the way his actions serve to disenfranchise Dana. Once he goes to the past, however, he must not
