The point applies to the intensions of proper names as well as natural kind terms. What these considerations suggest, as similar considerations later suggested to Gareth Evans (1982), Saul Kripke (1980) and Hilary Putnam (1975), is that names and natural kind terms do not pick out their referents descriptively: mastery of either proper names or natural kind terms does not require that we associate with them any reference-determining description. Jones, however, doesn’t draw this bold conclusion.
