17th-century Iberian and Italian scholastics had a concept of a truthmaker [verificativum] similar to that found in contemporary metaphysical debates. I argue that the 17th-century notion of a truthmaker can be illuminated by a prevalent 17th-century theory of truth according to which the truth of a proposition is the mereological sum of that proposition and its intentional object. I explain this theory of truth and then spell out the account of truthmaking it entails.

Seventeenth century scholastics had a rich debate about the ontological status and nature of lacks, negations, and privations. Realists in this debate posit irreducible negative entities responsible for the non-existence of positive entities. One of the first scholastics to develop a realist position on negative entities was Thomas Compton Carleton. In this paper I explain Carleton's theory of negative entities, including what it is for something to be negative, how negative entities are individuated, whether they are abstract or concrete, and (...) how they affect their subjects. I argue that for Carleton, negative entities are conceived as spatially extended simples that affect their subjects by means of spatial overlap. I also show how Carleton responds to some theological worries about his realism concerning negative entities. (shrink)

In this paper I argue that there is a difficulty for Fine's exact semantics for counterfactuals. The difficulty undermines Fine's reasons for preferring exact semantics to possible worlds semantics.

It is necessarily true that water is H2O, but it is a contingent fact that there is any water at all. Water therefore seems ill suited to ground the necessary truth that water is H2O. One view traditionally attributed to Scotus and Henry of Ghent was that while water is contingent, the essence of water is necessary; hence, the essence of water can ground the so-called eternal truth that water is H2O. Francisco Suárez rejects this view on the grounds that (...) it contradicts the Christian doctrine of creation, according to which everything other than God was contingently created in time. Suárez’s own view of the eternal truths has proven elusive to commentators, but I argue that Suárez ultimately endorses a version of the view he rejects: essences ground the eternal truths. But this raises several puzzles: how is Suárez’s view distinct from the views traditionally ascribed to Scotus and Henry? How does Suárez’s view escape the argument from creation, which Suárez raises against his opponents? I argue that Suárez distinguishes between his view and his opponents’ view by saying that essences have “extrinsic being,” whereas his opponents claim that essences have “intrinsic being.” The distinction between intrinsic and extrinsic being has not received much attention, but I argue that it marks an important fault line in scholastic thinking about the ontological status of non-existents. I argue that the notion of extrinsic being can be explicated in terms of ontological pluralism and grounding. The notion of extrinsic being helps differentiate Suárez’s view from his Scotistic and Henrician opponents, and it allows Suárez to respond to the creation argument he raises against his opponents. On my reading, Suárez’s solution to the problem of eternal truths turns out to be both highly original and philosophically satisfying. (shrink)

An early modern scholastic conception of moral possibility helps make sense of Descartes's own perplexing use of that concept and solves the exegetical puzzles surrounding Descartes's conflicting remarks about free will.

For Francisco Suárez, beings of reason are non-existent objects that we can think about, objects like goat-stags and round squares. The first section of the fifty-fourth of Suárez’s Metaphysical Disputations is about the ontological status of beings of reason. Suárez’s view has been the subject of disagreement in the literature because he sometimes says that there are beings of reason, and he sometimes says there are not. In this paper, I argue for and explain an ontological pluralist reading of Suárez. (...) Ontological pluralism is the claim that there is more than one way of being. I distinguish between two varieties of ontological pluralism, strict and non-strict, and argue that Suárez endorsed the latter. In the contemporary literature, it is sometimes alleged that ontological pluralism is an idle hypothesis, unintelligible or philosophically vacuous. I argue that Suárez has a response to this objection in his argument against ontological monism. (shrink)

Scott Davison has raised an epistemic challenge to the doctrine of petitionary prayer. Roughly, the challenge is that we cannot know or have reason to believe that a prayer has been answered. Davison argues that the epistemic challenge undermines all the extant defenses of petitionary prayer. I argue that it does not.
