It is a philosophical truism that we must think of others as moral agents, not merely as causal or statistical objects. But why? I argue that this follows from the best resolution of an antinomy between our experience of morality as necessarily binding on the will and our knowledge that all moral beliefs originate in contingent histories. We can address this antinomy only by understanding moral deliberation via interpersonal relationships, which simultaneously vindicate and constrains morality’s bind on the will. This (...) means that moral agency is fundamentally social. I model an attitude toward our causal nature on sociologist Erving Goffman’s concept of ‘civil inattention’; our social practice of agency requires that we give minimal attention to the contingent origins of moral judgments in ourselves and others. Understood this way, seeing ourselves as moral agents requires avoiding appeal to causal aetiology to settle substantive moral disagreement. (shrink)
