Abstract

This paper defends a new version of truthmaker non-maximalism. The central feature of the view is the notion of a default truth-value. I offer a novel explanation for default truth-values and use it to motivate a general approach to the relation between truth-value and ontology, which I call truth-value-maker theory. According to this view, some propositions are false unless made true, whereas others are true unless made false. A consequence of the theory is that negative existential truths need no truthmakers and that positive existential falsehoods need no falsemakers.
