Hasian contends that "eugenics" is an ambiguous term that has allowed people to voice their concerns on a number of social issues--a form of discourse that influences the way ordinary citizens make sense of their material and spiritual world. While biological determinism and social necessity are discussed in the works of Plato, Malthus, and Darwin, among others, with theories ranging from equality for all to natural superiority, it is Galton's observations on "positive" and "negative" eugenics that have been widely used to justify a variety of social and political projects--including the sterilization and segregation of the unfit, immigration restrictions, marriage regulations, substance abuse, physical and mental testing, and the establishment of health programs that sought to improve "hygiene." Women, African Americans, and other marginalized communities, for instance, have at times lost reproductive rights in the name of "liberty," "opportunity," or "necessity."
Eugenical arguments are more than a creation of pseudo-science or misapplied genetical analysis, Hasian determines; they are also rhetorical fragments, representing the ideologies of multitudes of social actors who, across time, have reconfigured these ideas to legitimize many agendas.
