Definition

The truthmaker requirement is the contested premise that a truth about absolute absence would require a way things stand that makes it true. The author uses it to argue that a state in which nothing obtains would already involve something. The corpus explicitly acknowledges that rejecting truthmakers of this kind undercuts this step, while keeping its separate account of real possibility.

Explanation

AB formulates a reductio: absolute nothing would exclude things, properties, relations, space, time and possibility, yet its obtaining would itself constitute a fact. The crucial inference is not merely that someone utters a sentence; it is that the sentence’s truth requires a fact or state of affairs.

The next paragraph makes that commitment visible and disputable. RB3 repeats the caveat in its epilogue notes, separating the claim that this reality is never null from the stronger claim that nothingness is impossible in every possible world. The former does not entail the latter without additional reasoning.

The author maintains a residual plenum of real possibility independently of that truthmaker move. The disagreement with subtraction arguments also concerns starting points: independently removable concrete objects and local resolutions of a preindividual field are different ontological pictures. The assessment preserves these commitments without declaring the philosophical dispute settled.
