Abstract

In this article, I want to focus on time and development in Kripke’s “Naming and Necessity” by considering two topics: (1) the evolution of scientific knowledge; (2) the evolution of biographies. In connection with (1) I suggest the introduction of a sentence operator for epistemic possibility and argue that some of Kripke’s strong metaphysical statements are finely counterbalanced by rather “Popperian” epistemological considerations. In connection with (2) I consider the idea of exploiting necessity of origin for a crossworld identity criterion
