 A third set of models is integrationist in character. Integrationists use the observations of sociologists of science to develop alternative accounts of scientific rationality and objectivity. Nelson (1990) focuses on a slightly different aspect of Quine’s holism than does Hesse. Nelson uses Quine’s arguments against the independently foundational status of observation statements as the basis for what she calls a feminist empiricism. According to Nelson, no principled distinction can be made between the theories, observations, or values of a community. What counts as evidence, in her view, is fixed by the entire complex of a community’s theories, value commitments, and observations. There is neither knowledge nor evidence apart from such a shared complex. The community is the primary knower on this view and individual knowledge is dependent on the knowledge and values of the community.
