This article critically evaluates the conception of conscience underlying the debate about the proper place and role of conscience in the clinical encounter. It suggests that recovering a conception of conscience rooted in the Catholic moral tradition could offer resources for moving the debate past an unproductive assertion of conflicting rights, namely, physicians’ rights to conscience versus patients’ rights to socially and legally sanctioned medical interventions. It proposes that conscience is a necessary component of the moral life in general and (...) a necessary resource for maintaining a coherent sense of moral agency.
