Respected Australian philosopher D.M. Armstrong discusses universals, properties and trope theory. First, he discusses the trope theory of Donald Williams. Then he discusses the distinction between bundle theories of properties and substance-attribute theories, then moves on to discuss categorical properties and powers, before discussing the topic of contingent and necessary predication. Although it doesn’t look like Armstrong is radically changing his views from those which he expressed in either his "Opinionated Introduction" to the subject of universals or his lengthy discussion in "Universals and Scientific Realism", it certainly looks like an interesting discussion.
