RT Journal Article SR Electronic T1 Conscientious objection: unmasking the impartial spectator JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 677 OP 678 DO 10.1136/medethics-2019-105698 VO 45 IS 10 A1 Toni C Saad YR 2019 UL http://jme.bmj.com/content/45/10/677.abstract AB Hoping to bring some objectivity to the debate, Ben-Moshe has argued that conscientious objection in medicine should be accommodated based on its concordance with the ‘impartial spectator’, a metaphor for conscience drawn from the writings of Adam Smith. This response finds fault with this account on two fronts: first, that its claim to objectivity is unsubstantiated; second, that it implicitly relies on moral absolutes, despite claiming that conscience is a social construct, thereby calling its coherence and claims into question. Briefly, a traditional account of conscience is then described, before ending with a related thesis for future discussion.
