 Separatists, on the other hand, work with a determination-based conception of grounding. The guiding idea here is an analogy between causation and grounding. Causation, while itself a form of determination rather than explanation, nevertheless backs explanations. So too separatists claim with grounding: grounding, rather than being a form of explanation, is a form of determination—what we will call determinationG—that backs explanations (Audi 2012a; Schaffer 2009, 2012, 2016a; Trogdon 2013a). For separatists, to say that the bowl’s brittleness is grounded in the ionic bonds of its constituent atoms is, in the first instance, to say that these bonds non-causally generate, produce, or bring about the bowl’s brittleness. Just what the intuitive notion of backing ultimately comes to in the context of causation and grounding isn’t an entirely settled matter—some understand backing in terms of representation (Trogdon 2018a), while others suggest that backing itself is to be given a grounding-theoretic treatment (Kovacs 2020; Wirling 2020). (The “explanationG” and “determinationG” terminology is borrowed from Skiles and Trogdon (2021)).
