 At the heart of this view is what Baker has recently labeled her “Key Distinction” (2007: 43; 2016: 53). Constitutionalists maintain that constituting objects (e.g., pieces of marble) and constituted objects (e.g., statues) can share some of their properties. For instance, a statue shares its physical and aesthetic properties with the piece of marble that constitutes it; likewise, Baker will claim, a person shares its physical and psychological properties with the human animal that constitutes it. But these objects cannot share all of their properties in the same way, or else there would be no difference between the constituting and the constituted. So Baker draws an exhaustive and mutually exclusive distinction between two ways that objects can instantiate properties: derivatively or nonderivatively. Roughly, an object has a property derivatively if it instantiates it only in virtue of being colocated with another object, whereas an object instantiates a property nonderivatively if it instantiates that property independently of being colocated with another object. We might express this distinction more perspicuously as follows. If one object (x) constitutes another object (y) and both objects instantiate some property (F), then
