Would this paper exist if I hadn’t written it?

This paper wants to know whether it would exist, or could exist, in worlds in which I didn't write it. Before we can answer this question, we first of all have to inquire as to what, exactly, this paper is. After exploring two forms of Platonism (pure and impure), and a theory that defines literary works in terms of events, I shall argue that the term ‘this paper’ is actually infected with ambiguity. Does this paper need me? It depends upon what you mean by ‘this paper’. I lay out the options for what you might mean, and answer the question for each of the options.
