The identity of property particulars

A property particular is a particular that characterizes the satisfaction of a property by an object, for example the 'redness' of a specific rose. We consider three theories of identity for property particulars, illustrating them on a common example. We discuss their strengths and weaknesses, and whether they can be in- terpreted in an epistemic or realist perspective. We introduce some first steps of a theory of reification of property types and discuss the benefits that it could bring.
