Abstract

Like many contemporary truthmaker theorists, seventeenth-century scholastics were concerned about the problem of finding truthmakers for negative truths such as “Pegasus does not exist.” This paper argues that the early modern scholastic Francisco Peinado’s solution to the problem of negative truths is to claim, roughly, that negative truths do not have truthmakers. The position attributed to Peinado is widely rejected nowadays as ad hoc, but this paper argues that Peinado’s position is independently motivated because he independently endorses the intentional mode view of affirmation and negation, a certain analysis of truth for positive truths, and the aboutness constraint on truthmaking. He endorses the intentional mode view because he thinks it alone can account for the distinction between positive and negative force, and it alone can account for the difference between positive and negative propositions.
