Grounding talk has become increasingly familiar in contemporary philosophical discussion. Most discussants of grounding think that grounding talk is useful, intelligible, and accurately describes metaphysical reality. Call them realists about grounding. Some dissenters reject grounding talk on the grounds that it is unintelligible, or unmotivated. They would prefer to eliminate grounding talk from philosophy, so we can call them eliminitivists about grounding. This paper outlines a new position in the debate about grounding, defending the view that grounding talk is (or at least can be) intelligible and useful. Grounding talk does not, however, provide a literal and veridical description of mind-independent metaphysical reality. This (non-eliminative) irrealism about grounding treads a path between realism and eliminativism.

10 Explanation is generally considered to be transitive, asymmetric, irreflexive, non-monotonic and hyperintensional.
11 This is the strategy taken by Rosen in ‘Metaphysical Dependence: Grounding and Reduction’, and by Trogdon in ‘An Introduction to Grounding’, amongst others.

25 I assume here that irrealists about grounding will maintain that it is at least sometimes appropriate to make a claim about grounding (I think they might also take such claims sometimes to be true). I defend this claim in sections 3 and 4.

30 For those who think causation is a primitive relation, the cases are much more similar. Knowledge of primitive causal relations would be hard to come by.

33 Of course, not all sentences about grounding are false according to the error theorist. Sentences like ‘there are no grounding relations’, ‘A doesn't ground B’ and ‘B is ungrounded’ might all be true (because they don't commit us to the existence of grounding relations). As is standard, I describe the error theorist's commitment as being to the systematic falsity of grounding sentences in order to circumvent this complication.

41 This is arguably the position of Field in Science Without Numbers (Princeton: Princeton University Press, 1980)Google Scholar, where he defends the view that there are compelling instrumentalist justifications for continuing to engage in mathematical discourse, but declines to say what, if anything, mathematical utterances might be used to assert.
