 Most generally feminists are united in urging recognition of the social contexts in which scientific research takes place and scientific knowledge is received. As such, feminist approaches to science are situated in broader movements in philosophy of science and science studies that emerged during the second half of the twentieth century. Such approaches acknowledge and explore the social nature of scientific knowledge (for example: Kuhn 1962 [1970]; Longino 1990, 2002; Kitcher 1993, 2001; Solomon 2001). Additionally, they are situated in the liberatory movements of the 1960s and 1970s. As the participation of women in the sciences increased in the second half of the twentieth century, the effects of the absence of women as researchers and women’s lives as subjects of knowledge were more readily apparent. The coinciding feminist movements during the same period provided frameworks through which to theorize these lacunae and understand them as aspects of oppression.
