Unionists about grounding and grounding explanation owe an account of how the metaphysical and explanatory elements of metaphysical explanation can be held together coherently, or else must jettison one element or the other.
Grounding explanation(Contrasted with grounding as a metaphysical relation)
A form of metaphysical explanation in which facts about what grounds what back or underwrite explanatory claims, modeled in part on the quasi-causal structure of causal explanation.
Jettison(general philosophical usage)
To throw overboard or abandon; in philosophy, to give up on a particular theory or requirement.
Unionists (about grounding)(metaphysics)
Philosophers who believe that grounding is fundamentally one thing—that its explanatory power and its metaphysical reality are the same feature, not two separate things.
grounding(Drawn from contemporary metaphysics; proposed as potentially applicable to understanding the foundations of legality.)
A metaphysical relation in which some entities or facts are more foundational than others, providing a hierarchical structure of the world.
metaphysical(Ayer's Logical Positivist usage)
Language that purports to refer beyond the physical world and lacks empirical consequences, which Ayer classifies as not literally significant
metaphysical explanation(At least three varieties are distinguished in recent literature regarding how property-sharing explains resemblance)
An explanation of why a fact obtains in terms of what grounds or accounts for it at the level of fundamental reality, not merely causal or logical explanation
Following Raven (2015), who applies the terminology to grounding and grounding explanations in particular, approaches to this fundamental question might be classified with regard to whether they take a “unionist” or “separatist” line. Standardly, unionism about grounding and grounding explanation is the thesis that they are one: to be grounded just is to be metaphysically explained in a distinctive way (e.g., Dasgupta 2014; Jenkins 2013; Litland 2013, 2017; Raven 2012; Rosen 2010; Thompson 2016)
