Existence is not a property of an object. It is a property of properties.

For example, when we say “X does not exist”, we do not mean that “there is an X and X has a property of non-existence.” Instead, existence is a property of the collection of other objects.

Existence is a property of the system that X is in. 

X exists

= the system has the component X

= the system has the property of “having X”

X doe not exist

= no systems have the component X

= no systems have the property of “having X”
