 Price recognizes that our various duties may conflict in a particular case: the only way to prevent harm may be to lie; acting justly may be imprudent, and so on. He maintains that in some cases one duty is clearly weightier than another and no perplexity arises. But there are many cases where it is not clear what is the right thing to do, and conscientious people may differ as to which duty should give way in such cases. There is always a determinate answer to the question of which action is right, but as finite creatures we may lack penetration and wisdom to discern it. Doubt about what we should do in a particular case should not, however, infect our confidence in the existence of objective moral truth, for the fundamental principles that we bring to bear on particular cases are self-evident.
