 The second problem with this easy solution is deeper. Even if it were plausible to arrange moral precepts hierarchically, situations can arise in which the same precept gives rise to conflicting obligations. Perhaps the most widely discussed case of this sort is taken from William Styron’s Sophie’s Choice (1980, 528–529; see Greenspan 1983 and Tessman 2015, 160–163). Sophie and her two children are at a Nazi concentration camp. A guard confronts Sophie and tells her that one of her children will be allowed to live and one will be killed. But it is Sophie who must decide which child will be killed. Sophie can prevent the death of either of her children, but only by condemning the other to be killed. The guard makes the situation even more excruciating by informing Sophie that if she chooses neither, then both will be killed. With this added factor, Sophie has a morally compelling reason to choose one of her children. But for each child, Sophie has an apparently equally strong reason to save him or her. Thus the same moral precept gives rise to conflicting obligations. Some have called such cases symmetrical (Sinnott-Armstrong 1988, Chapter 2).
