 Another common approach to argue for value incommensurability is with reference to “non-symmetrical” dilemmas. As the name suggests, in non-symmetrical dilemmas, the alternatives are favored by different values (Sinnott-Armstrong 1988). If these values are incommensurable in the third sense as discussed in subsection 1.3, there is no systematic resolution of the value conflict. Consider Jean-Paul Sartre’s well-known example of his pupil who faced the choice between going to England to join the Free French Forces and staying at home to help his mother live (Sartre 1975, 295–296). No matter which alternative he chooses, certain values will remain unrealized. An idea along these lines is considered, for example, by Walter Sinnott-Armstrong (1988, 69–71) and Bernard Williams (1981, 74–78) in their discussions of moral dilemmas.
