 Does this mean that we should join Bigelow in his retreat to (Truth Supervenes Upon Being) or step back with Lewis to (Subject Matter)? The problem is that these supervenience principles don’t seem a satisfactory resting place either, not if our concern is to understand how true representations can touch upon an independent reality, i.e., something non-representational. First, it is familiar point that just appealing to a systematic pattern of modal co-variation between truths and their subject matters—so that there is no difference in the former without a difference in the latter—doesn’t provide us within any insight into the underlying mechanism or mechanisms that sustains this dependency (Molnar 2000: 82–3; Heil 2003: 67; Daly 2005: 97–8; Melia 2005: 82–3). Second, if possible worlds are conceived as maximal representations then these supervenience principles (understood in the idiom of possible worlds) fail to articulate what it is for a representation to touch upon being, something non-representational: “For the idea that every truth depends on being is not the idea that every truth is entailed by propositions of a certain sort” (Merricks 2007: 86).
