The gender, race, or class consciousness is an achievement forced on everyone by the terrible historical experience of the contradictory social realities of patriarchy, colonialism, racism, and capitalism. Against that project of modernity centred on the unified masculine subject, the sustained and damaging critique put into play by the insights of various strands of poststructuralism has fundamentally contested the very ontological status of conventional notions of subjectivity. The subjectivity, is not the manifest property of an interior self but merely a more or less unstable effect of power. And that for feminism must indicate the liberatory potential to refuse the assignment of our identities by the dominant discourse. The feminist representation of the insights of postmodernism regarding the body will have significant implications for the issue of health care, and in turn for bioethics. The determination of sexual difference in opposition is destined, designed, in truth, for truth; it is so in order to erase sexual difference.
