 Currie objects that Levinson’s ontological category, structure as indicated-by-artist at time t, is metaphysically obscure (1989, 58). Fleming discovered penicillin, but do we believe that in so doing he also created the entity, penicillin-as-discovered-by-Fleming? Levinson is explicitly committed to the idea that when the artist indicates or discovers or chooses an abstract structure, “something further comes into existence,” namely, an initiated type (1990, 262). Currie’s point is that if this is allowed, various unwanted ontological commitments follow. A related criticism raised by Dodd (2000), Predelli (2001), and Alward (2004) is that indicating is not really a matter of creating, and if this is correct, it follows that Levinson’s proposal does not satisfy a sufficiently robust version of the first of his three requirements on an adequate ontology of the relevant sorts of works.
