Ground is all the rage in contemporary metaphysics. But what is its nature? Some metaphysicians defend what we could call, following Skiles and Trogdon (2021), the inheritance view: it is because constitutive forms of metaphysical explanation are such-and-such that we should believe that ground is so-and-so. However, many putative instances of inheritance are not primarily motivated by scientific considerations. This limitation is harmless if one thinks that ground and science are best kept apart. Contrary to this view, we believe that (...) ground is a highly serviceable tool for investigating metaphysical areas of science. In this paper, we defend a naturalistic version of the inheritance view which takes constitutive scientific explanation as a better guide to ground. After illustrating the approach and its merits, we discuss some implications of the emerging scientific conception for the theory of ground at large. (shrink)

Antirealism about metaphysical explanation is relatively underexplored. This paper maps out the territory for the antirealist, explaining what it would take to be an antirealist given various different conceptions of metaphysical explanation, and of the relationship between metaphysical explanation and grounding.

Grounding necessitarianism (GN) is the view that full grounds necessitate what they ground. Although GN has been rather popular among philosophers, it faces important counterexamples: For instance, A=[Socrates died] fully grounds C=[Xanthippe became a widow]. However, A fails to necessitate C: A could have obtained together with B=[Socrates and Xanthippe were never married], without C obtaining. In many cases, the debate essentially reduces to whether A indeed fully grounds C – as the contingentist claims – or if instead C is (...) fully grounded in A+, namely A plus some supplementary fact S (e.g. [Xanthippe was married to Socrates]) – as the necessitarian claims. Both sides typically agree that A+ necessitates C, while A does not; they disagree on whether A or A+ fully grounds C. This paper offers a novel defence of the claim that, in these typical cases, unlike A+, A fails to fully ground C – thereby bringing further support to GN. First and foremost, unlike A+, A fails to fully ground C because it fails to contain just what is relevant to do so, in two distinct senses – explanatory and generative relevance. Second, going for A, rather than A+, as a full ground undermines not just grounding necessitarianism, but modally weaker views which even contingentists may want to preserve. (shrink)

Contemporary metaphysics has undergone a change of perspective due to the irruption of Grounding in discussions of metaphysical dependence. Proponents argue that Grounding is the primitive relationship of determination underlying many of the traditionally posited idioms of metaphysical dependence. In a recent line of scepticism Jessica Wilson has argued that the inability of the notion to be informatively effective regarding substantial matters of metaphysical determination renders it useless in the face of theoretical work. To supply this lack of informativeness proponents (...) must resort to the already available set of specific ‘small-g’ relations, which renders the formulation of ‘big-G’ Grounding pre-theoretically unmotivated. In response two motivations are said to remain: The priority and unity arguments. Wilson insists that neither of these motivations succeeds in establishing ‘big-G’ Grounding as theoretically useful. I argue that none of Wilson’s critiques succeeds in establishing eliminative scepticism. (shrink)

A recent methodological approach at the interface of metaphysics and philosophy of science suggests that just like causal laws govern causation, there needs to be something in metaphysics that governs metaphysical relations. Such laws of metaphysics would be counterfactual-supporting general principles that account for the explanatory force of metaphysical explanations. There are various suggestions about how such principles could be understood. They could be based on what Kelly Trogdon calls grounding-mechanical explanations, where the role that grounding mechanisms play in certain (...) metaphysical explanations mirrors the role that causal mechanisms play in certain scientific explanations. Another approach, by Gideon Rosen, takes it that there are essentialist principles or laws that tell us about what grounds what. Finally, Jonathan Schaffer defends an approach that he considers to be neutral regarding grounding or essences. In this paper I will assess these suggestions and argue that for those willing to invoke a non-modal notion of essence, there is a more promising route available: metaphysical and scientific explanations may be unified in terms of general essences. Accordingly, essentialists may be better viewed as outlaws when it comes to laws of metaphysics. (shrink)

This chapter is a guide to the basics of metaphysical grounding. It offers an accessible overview of its features and uses, comparing this concept with other forms of dependency one can find in the literature. It emphasizes two major theoretical roles grounding is claimed to play in philosophical theorizing: (i) accounting for a distinctive form of non-causal determination and (ii) illuminating the hierarchical structure of reality. The chapter aims to persuade the reader of the usefulness of grounding by discussing how (...) some objections targeting these roles can be mitigated. -/- Este capítulo es una guía para conocer los elementos básicos de la fundamentación metafísica. Ofrece una revisión accesible de sus características y usos, comparando este concepto con otras formas de dependencia que se pueden encontrar en la literatura. Enfatiza dos roles teóricos centrales que la fundamentación supuestamente juega en la teorización filosófica: (i) dar cuenta de una forma distintiva de determinación no causal y (ii) entender mejor la estructura jerárquica de la realidad. El capítulo apunta a persuadir a las lectoras de lautilidad de la fundamentación discutiendo cómo pueden mitigarse algunas objeciones dirigidas a esos roles. (shrink)
