 Pluralism and naturalized moral epistemology as upshots of value-laden inquiry. Because inquirers select background assumptions in part for their fit with their varied interests and values, their background assumptions will also vary. Feminist epistemologists urge us to embrace this fact (Haraway 1991, Harding 1998, Longino 2001). Pluralism of theories and research programs should be accepted as a normal feature of science. As long as the different research programs are producing empirical successes not produced by the others, and avoiding clear error and viciously circular or dogmatic reasoning, we should treat the value-biases animating them as epistemic resources, helping us discover and understand new aspects of the world and see them in new perspectives. Feminist science takes its place as one set of legitimate research programs among others. This does not imply relativism. Value-laden research programs are still open to internal and external critique. A naturalized epistemology that rejects neutrality allows that observations may undermine any background assumptions, including value judgments (Anderson 2004).
