Add to ORKGJoseph LaPorte in an article on \u27Kind and Rigidity\u27 (Philosophical Studies, Volume 97) resurrects an old solution to the problem of how to understand the rigidity of kind terms and other general terms. Despite LaPorte\u27s arguments to the contrary, his solution trivializes the notion of rigidity when applied to general terms. His arguments do lead to an important insight however. The notions of rigidity and non-rigidity do not usefully apply at all to kind or other general terms. Extending the notion of rigidity from singular terms such as proper names to general terms such as natural kind terms is a mistake. © 2002 Kluwer Academic Publishers
