This chapter explains the way the word ‘property’ is used in the book, and why that use is compatible with the doctrines of Resemblance Nominalism. It argues that the Problem of Universals, understood as the One over Many, has the general form Nozick finds in many philosophical problems: ‘How is a certain thing possible given, or supposing, certain other things’. The chapter argues that since the Problem of Universals has this form, solutions to it must account for the truthmakers, as opposed to the conceptual content or ontological commitment, of certain sentences. Several solutions to the Problem of Universals are reviewed.
