Here Chatton gives us a test for when a certain number of entities is insufficient to make a true sentence true. His test is phrased in terms of the consistency of the falsehood of the proposition and the existence of certain things without another. By studying other texts we are able to see that Chatton has in mind a kind of a priori version of Mill’s methods. We are to imagine, within the absolute power of God, whether the causal powers attributed to the kinds of entities in a given ontological snapshot would be sufficient to make the proposition in question turn out true. If they are not, we then imagine other entities coming into being, adding each to the ontological snapshot one at a time, checking to see after each addition whether the proposition would at that point have to be true. So long as the insufficiency remains, we add another object to the picture. We check that the insufficiency remains via consistency: so long as there remains no manifest contradiction between the existence of the currently considered snapshot and the falsehood of the proposition, the insufficiency remains, and we must continue to posit more things. Given this method, it would seem to follow that, for any set of entities, if the causal powers of those entities are found wanting on the basis of consistency and yet the proposition in question were known to be true, then another kind of entity, with its attendant causal powers, would have to exist.
