Thesis advisor: Richard Cobb-Stevens / In this dissertation, I develop an engaged understanding of objectivity, or good knowledge practices. I argue that for knowledge practices to be good, they must both be truth-conducive and engaged, that is, explicitly implicated in the critical appraisal of background values and assumptions. I pursue this argument in six stages. First, I consider work in epistemology that countenances a place for values in objectivity. I conclude from this that truth-conduciveness is not sufficient for objectivity, and that a social approach to knowledge is called for. Second, I consider standpoint theory, a prominent feminist approach to objectivity. This allows me to show the possible insights available to marginalized perspectives, while indicating that this will be a component of rather than itself offering an account of objectivity. Third, I consider a more comprehensive approach in Helen Longino's critical contextual empiricism, which locates objectivity in the social features of inquiry. Her approach is promising, but requires the insights of early phenomenology in order to develop that potential. I develop the phenomenological framework in Chapter 4, where I consider Husserlian phenomenology. Fifth, I bring the insights of phenomenology to the challenges presented by critical contextual empiricism, and develop my positive view, critical phenomenological objectivity. On this view, inquiry is objective when individuals and communities foster critical perspectives, seek transformative epistemic experiences, build coalitions, foster diversity, and pursue empirical adequacy. In the final chapter, I consider a case study that enables me to defend the merit and warrant of these features of objectivity. / Thesis (PhD) — Boston College, 2009. / Submitted to: Boston College.

Feminist philosophy of science has long been considered a fringe element of philosophy of science as a whole. A careful consideration of the treatment of the key concept of objectivity by such philosophical heavyweights as Thomas Kuhn and Karl Popper, followed by an analysis of the concept of objectivity with the work of such feminist philosophers of science as Donna Haraway, Lynn Hankinson Nelson, and Sandra Harding, reveals that feminist philosophers of science are not members of some fringe movement of philosophy of science, but rather are doing philosophical work which is both crucial and connected to the work of other, "mainstream" philosophers of science. / Master of Arts
