In a recent issue of this journal, Gamble and Saad offer a taxonomy of conscientious objection in health care with the aim of increasing the common ground in the debate over conscientious objection to prevent parties from talking past each other and help facilitate greater progress on this issue. Although we agree that this is an important and worthwhile project, Gamble and Saad's proposal suffers from several serious weaknesses that limit its ability to do the work set out for it. (...) In this paper, we identify some of the major problems with this particular attempt in order to highlight some desiderata for a taxonomy of conscientious objection in health care that can serve as a guide for developing improved taxonomies of this kind in the future.
