This chapter summarises the main lessons gathered in the book. It explains that the arguments developed in the referentialist revolution, when properly understood, show that names have a Millian semantics. The main conclusions are that the metasyntactic interpretation of two-dimensionalism introduced in this book is the only form of descriptivism that remains compatible with this result, and that in turn the metasyntactic account will be compatible with an account of indexical thought inspired by David Lewis.
