 Another issue is whether grounding is well-founded. Different authors mean different things in claiming that grounding is well-founded. According to Schaffer, grounding is well-founded in the sense that downwardly non-terminating chains of grounds are impossible. In conceiving of grounding as a relation between entities in general and not just facts, Schaffer’s rationale concerns the notion of reality inheritance. Schaffer claims that, were there downwardly non-terminating grounding chains, the being of any object in such a chain would be “infinitely deferred, never achieved” (2010: 62). Something “…cannot be real merely by having a limitless sequence of ancestors, each claiming reality from its parents”; instead, “There must actually be a source of reality somewhere” (2016a: 95). This echoes Leibniz, who claims that in the event that every object is a being of aggregation, “one never arrives at any real being” (Adams 1994: 333).
