Metasemantics out of Economics?

This chapter discusses the application of formal methods from social choice theory to the metasemantic question of whether radical interpretation is possible. Radical interpretation involves deducing semantic truths from non-semantic truths by appeal to certain a priori principles or criteria, such as the principle of charity. A familiar view is that the intended interpretation is the one that best meets a combination of constraints. It is suggested that this situation can be modelled as follows: each constraint determines a binary relation on the set X of interpretations (‘x is at least as good as y with respect to the ith constraint’) that is transitive and complete. The radical interpreter’s task is to determine an overall ordering as a function from the profile of individual orderings. The application of Arrow’s theorem in this context is discussed.
