In a recent article in this journal, Steve Clarke (2017) identifies two different bases for conscience-based refusals in healthcare: (1) all-things-considered moral judgments, and (2) the dictates of conscience. He argues that these two bases have distinct roles in justifying conscientious objection. However, accepting that there are these two bases, I argue that both are not able to justify conscientious objection. In particular, I argue that the second basis of the dictates of conscience cannot justify conscience-based refusal in a healthcare (...) context. Even if someone objects in a healthcare context on the basis of the dictates of her conscience, and even if we can explain why she objects with reference to the dictates of her conscience, her objection will only be justified if she makes a judgment.
