Grounding Entails Counterpossible Non‐Triviality

This paper outlines a non‐reductive counterfactual account of grounding along interventionist lines, and uses the account to argue that taking grounding seriously requires ascribing non‐trivial truth‐conditions to a range of counterpossible counterfactuals. This result allows for a diagnosis of a route to scepticism about grounding, as deriving at least in part from scepticism about non‐trivial counterpossible truth and falsity.
