Understanding the argument -
Philosopher: Nations are not literally persons; they have no thoughts or feelings, and, literally speaking, they perform no actions. - Background information.
Thus, they have no moral rights or responsibilities. - Intermediate conclusion.
But no nation can survive unless many of its citizens attribute such rights and responsibilities to it, for nothing else could prompt people to make the sacrifices national citizenship demands. - "but" introduces a contrast. This means that the false belief that nations have such moral rights or responsibilities is the minimum condition for a nation's survival.
Obviously, then, a nation __________.
Which one of the following most logically completes the philosopher’s argument?
(A) cannot continue to exist unless something other than the false belief that the nation has moral rights motivates its citizens to make sacrifices - it means "cannot continue to exist unless something other than the false belief motivates its citizens." If nothing other than the false belief motivates its citizens, the nation cannot continue to exist." This Means " the country continues to exist, implying there is something other than the false belief to motivate," an idea that contradicts the argument. As per the argument, "the false belief is the minimum condition for the nation to exist."
(B) cannot survive unless many of its citizens have some beliefs that are literally false - means "can survive implies many of citizens have a false belief." - as per the argument. Ok.
(C) can never be a target of moral praise or blame - out of scope.
(D) is not worth the sacrifices that its citizens make on its behalf - out of scope.
(E) should always be thought of in metaphorical rather than literal terms - out of scope.
