 Grounding theorists (who have generally been pessimistic about attempts to define grounding in other terms) will likely object that (8) wrongly entails that whenever \(p\) is fully grounded by \(qq\), and \(r\) is both true and more natural than \(p\) obtains, \(p\) is also fully grounded by \(qq\) together with \(r\) (even if \(r\) is intuitively completely irrelevant to \(p\)). One might try to refine (8) to avoid this objection by adding some further “relevance” condition, also explained in terms of naturalness; but it is not obvious how this should go.
