jats:pJago (2012) argues that truthmaker non-maximalism, the view that some but not all truths require truthmakers, is vulnerable to a challenge from truths which ascribe knowledge of propositions about things which don’t exist. Such truths, Jago argues, can only be dealt with using maximalist resources. I argue that Jago’s point relies on the claim that the relevant truths require truthmakers, a point that non-maximalists can coherently and plausibly deny. Moreover, I argue that by making use of a safety account of knowledge, non-maximalists can fully answer Jago’s challenge.</jats:p>
