Resumen de Nombres propios y términos de género natural: un examen de dos supuestas similitudes
According to Kripke, two important similarities between natural kind terms and proper names are that both types of expressions are rigid designators and that they appear in identity statements that are necessary if true; Kripke denominates these types of statements containing natural kind terms “theoretical identities”. Nevertheless, Kripke claims that the latter similarity follows from the former. In this paper I have a double aim. Firstly, I will contend that it can be held that natural kind terms are rigid designators their referents being universals. Secondly, I will argue that the conception of natural kind terms as rigid designators of universals hinders the establishment of the truth of theoretical identities and hence of their necessity.
