Abstract
In this paper, I set to analyze the kind of metaphysical essentialism that follows from Jerrold Levinson’s ontology of musical works. This paper is structured into three sections. In the first, I reconstruct those parts of Levinson’s ontology of musical works that entail essentialism. In the second section, I reconstruct Mackie’s and Forbes’ arguments for the indispensability of the individual essences of particular objects and show that they apply equally well to musical works. In the third, final section, I combine the conclusions of the two previous ones to prove that Levinson’s ontology of musical works is compatible with Mackie and Forbes’ postulate for the individal essences. I show, however, that even though Levinson correctly ascribes essential properties to musical works, his choice about which of those properties count as essential leads to counterintuitive consequences. I end this paper with a new argument showing that musical works do have essential properties but that they are different from those postulated by Levinson.
