Was Searle's Descriptivism Refuted?

It is generally thought that Searle's cluster theory of the sense of a proper name was soundly refuted by Kripke in Naming and Necessity. This paper challenges this widespread belief and argues that the observations made by Kripke do not show that Searle's version of descriptivism is false. Indeed, charitably interpreted, Searle's theory retains considerable plausibility.
