There is a strong intuition that we can listen to works of music, yet musical ontologies on which works of music are abstract objects, perhaps most notably, type theories of music, seem to imply that this is impossible. This problem has received relatively little attention in the literature. I here explore and develop a solution suggested by Julian Dodd and argue that it has at least two problematic consequences, namely (i) that some works of music cannot be listened to unless one has already studied the relevant score or through a similar process learned roughly what the work requires of its performances and (ii) that it is possible for two people to listen to different musical works while listening to the same performance.

Bertrand Russell’s _Principles of Mathematics_ (1903) gives rise to several interpretational challenges, especially concerning the theory of denoting concepts. Only relatively recently, for instance, has it been properly realised that Russell accepted denoting concepts that do not denote anything. Such empty denoting concepts are sometimes thought to enable Russell, whether he was aware of it or not, to avoid commitment to some of the problematic non-existent entities he seems to accept, such as the Homeric gods and chimeras. In this paper, I argue first that the theory of denoting concepts in _Principles of __Mathematics_ has been generally misunderstood. According to the interpretation I defend, if a denoting concept shifts what a proposition is about, then the aggregate of the denoted terms will also be a constituent of the proposition. I then show that Russell therefore could not have avoided commitment to the Homeric gods and chimeras by appealing to empty denoting concepts. Finally, I develop what I think is the best understanding of the ontology of _Principles of __Mathematics_ by interpreting some difficult passages.

Fictional realists maintain that fictional characters are part of the world’s ontology. In an influential article, Anthony Everett argues that the fictional realist is thereby committing herself to problematic entities. Among these are entities that are indeterminately identical. Recently, Ross Cameron and Richard Woodward have answered Everett’s worry using the same strategy. They argue that the fictional realist can bypass the problematic identities by contending that they are merely semantically indeterminate. This paper concisely surveys Everett’s original argument, Cameron’s and Woodward’s responses, and then argues that the strategy employed by Cameron and Woodward fails to satisfactorily answer Everett’s worries.
