 Mann’s argument for the thesis that everything is a property instance involves the notion of a rich property. The rich property of an individual x is a conjunctive property the conjuncts of which are all and only the essential and accidental properties, some of them temporally indexed, instantiated by x throughout x’s career (2015, 38). Mann tells us that for anything whatsoever there is a corresponding rich property. From this he concludes that “everything is a property instance of some rich property or other” (38). It follows that every person is a property instance. The argument seems to be this: (a) For every concrete individual x, there is a corresponding rich property R. Therefore, (b) for every concrete individual x, x is a property instance of some rich property or other.  Therefore, (c) For every concrete individual x, if x is a person, then x is a property instance.
