 That this may be a powerful criticism of Wiggins’s view can be seen by considering the notion of a Siamese object, which seemed to be necessary to answer the kind of problem posed by the sword-stick. The physical mass that houses both the sword and the walking stick can be identified independently of either. If this were not the case it is difficult to see how one could even make the mistake of thinking of it as one thing. The composites Siamese entities form are quite identifiable, and yet that entity is not supposed to fall under a sortal in its own right.
