I develop two different epistemic roles for emotion and desire. Caring for moral ends and people plays a pivotal though contingent role in ensuring reliable awareness of morally salient details; possession of various emotions and motives is a necessary condition for autonomous understanding of moral concepts themselves. Those who believe such connections compromise the "objective" status of morality tend to assume rather than argue for the bifurcated conception of reason and affect this essay challenges.

Sandra Harding is working on the reconstruction of scientific objectivity. Lorraine Daston argues that objectivity is a concept that has historically evolved. Her account of the development of "aperspectival objectivity" provides an opportunity to see Harding's "strong objectivity" project as a stage in this evolution, to locate it in the history of migration of ideals from moral philosophy to natural science, and to support Harding's desire to retain something of the ontological significance of objectivity.
