John Bigelow (Monash) and Martin Leckey (Melbourne) will present "New work for a hierarchy of universals" at 11 in Old Quad G10.

Abstract: "The friend of universals may wonder whether they would be better employed not as an addition to my ontology of *possibilia* and classes, but rather as a replacement for parts of it. A fair question and an urgent one, nevertheless, not a question considered in this paper." (David Lewis, "New work for a theory of universals", Australasian Journal of Philosophy 61 (1983), pp. 343-377). By contrast, in the present paper we will look into the possibility of replacing Lewis's hierarchy of classes of *possibilia* with the ontology of a categorial hierarchy of universals: properties, properties of properties, relations among properties of properties, ... and so on.
