Suppose that, corresponding to (i), the constituent of (10) includes exactly one of the contrary properties of sitting and not sitting: say, not sitting. Then it is hard to see how (10) is true, as it is at t, given that the object constituent is a bundle of properties including the property of not sitting. Suppose that, corresponding to (ii), both properties are among the bundle. Then it is hard to see how Bush exists, given that he is an inconsistent bundle of properties. Finally, suppose that
