Nothing to it?: generalized identity and zero-grounding

Abstract The aim of this paper is to make some headway in understanding the notion of zero-grounding. The account of grounding in terms of generalized identity, proposed by Correia and Skiles (2019), is employed to clarify issues of ground and zero-ground. I discuss some options for accommodating zero-grounding. According to one option, we slide dangerously close to violating the irreflexivity of ground. According to another option, zero-grounding leads to a worrying kind of overdetermination. A third option offers a way out, but a challenge remains of how best to make sense of it. I further contend that these arguments broaden to concern any notion of grounding according to which groundees are “nothing over and above” their grounds. Ultimately, the aim of this paper is exploratory. It lays out some of the different options and challenges that face the grounding theorist who wants to make sense of zero-grounding.
