Some wag (was it Mark Twain?) reported the following story: Scholars have recently established that the Iliad and the Odyssey were not, after all, written by Homer. They were actually written by another author, of the same name.
The majority of current theories of naming and reference, including ones as divergent in other respects as those of Russell and Searle, would rule this story impossible. They would do so on roughly these grounds: the sense and reference (one or the other, or one through the other, depending on the theory) of the name ‘Homer’ is determined, given the absence of other reliable testimony, by the sole description: ‘Author of the Iliad and the Odyssey’. ‘Homer is the author of the Iliad and the Odyssey’ is therefore known a priori, hence necessarily true. There could not be another author of that name and claim to fame.
In lectures delivered at Princeton in the Winter of 1970, Saul Kripke offered a lucid alternative to such theories (which I shall lump together under the term ‘descriptivism’).
