 Summing up: The primitive notion of ground is supposed to do justice to dependence claims, without any aspiration to further reduce this concept to modal or counterfactual concepts; and it has been suggested that explanatory connectives express this notion of ground. These preliminary remarks in mind, let us now turn to possible connections between redutcion and ground. First, there are two very general reasons to regard reduction as a particular variant of ground (5.3.2). At the same time, there appears to be a tension between reduction and ground. Either, reduction turns out to be distinct from ground, or the structural features of reduction may shed light on the nature of ground (5.2.3). Third, one may want to resist an assimilation of reduction to ground, based on a general skepticism towards the philosophical significance of grounding talk (5.2.4).
