Donna Haraway is the inspiration and genesis for cyberfeminism with her 1985 essay "A Cyborg Manifesto: Science, Technology, and Socialist-Feminism in the Late Twentieth Century" which was reprinted in "Simians, Cyborgs and Women: The Reinvention of Nature" (1991). Haraway's essay states that cyborgs are able to transcend the public and private spheres, but they do not have the ability to identify with their origins or with nature in order to develop a sense of understanding through differences between self and others. Shulamith Firestone and her book "The Dialectic of Sex: The Case for Feminist Revolution" has been named as a precursor to Haraway's work in cyberfeminism. Firestone's work focuses reproductive technology and advancing it to eliminate the connection of the feminine identity being connected to child birth. Firestone believed that gender inequality and oppression against women could be solved if the roles around reproduction did not exist. Both Firestone and Haraway had ideals based on making individuals androgynous, and both women wanted society to move beyond biology through improving technology.
