Graham Priest's book is a treasure-trove, with many interesting things to discuss, but in these remarks, I want to address two main questions.  The first concerns what properties and relations Priest's non-existent objects should have simpliciter.  The second is the question of whether Priest's framework needs dialetheism - should the framework only be attractive to those who accept true contradictions?  In these remarks I plan to grant, for the sake of discussion at least, that there are non-existent objects.  I take it that the question of whether there really are things that don't exist is one that is to be settled once  we see how well the rival theories do - and so developing a theory of non-existent objects seems to me an important preliminary to the judgement of whether there are, after all, such things.

To appear in a book symposium in Philosophy and Phenomenological Research.
