In this chapter, it is argued that the distinction defended in chapter 1 is a genuine rigid — nonrigid distinction because it assigns the right role to rigidity and nonrigidity. Rigidity performs the right duties: principally supporting the necessity and contingency of identity statements containing the right combination of rigid and nonrigid designators. Several other alleged duties have been said to belong to rigidity's role: these are rejected as not properly belonging to rigidity. They include securing essential property attributions, like ‘white is a color’, securing externalism, securing aposteriority, refuting descriptivism, and securing linguistic stability. None of these are really central to rigidity's role so it does not matter that rigidity does not perform them or perform them well.

Keywords: rigidity; nonrigidity; essential property; externalism; aposteriority; a posteriori; descriptivism; linguistic stability
