In my (2020), I criticize how Meinertsen in Metaphysics of States of Affairs treats the main ‘internal’ problem of his state of affairs ontology: the problem of unity. In this note, I consider instead some questions about Meinertsen’s approach to one of his important ‘external’ problems: the problem of non-substantial change.

In this piece I respond to commentaries by Julio De Rizzo & Benjamin Schnieder, Erwin Tegtmeier and William Vallicella on my book Metaphysics of States of Affairs (Springer, 2018).

In this paper, I relate key features of Adolf Reinach’s abundant ontology of propositional states of affairs of his to Armstrong’s—or an Armstrongian—state of affairs ontology, with special regard to finding out how sparse or abundant the latter is with respect to negative states of affairs. After introducing the issue, I clarify the notion of a propositional state of affairs, paying special attention to the notion of abstract versus concrete. I show how Reinach’s states of affairs are propositional, and how (...) they compare with Chisholm’s well-known propositional states of affairs. In the next section, I outline Reinach’s five roles for states of affairs and show that only one of them is relevant to Armstrongian state of affairs ontology. In the following section, I utilise this role to create a ranking of state of affairs ontologies according to how abundant they are. It is, however, unclear which level Armstrongian state of affairs ontology is at, since it is unclear if, like Reinach’s ontology, it includes negative states of affairs. In the final section, I argue that the answer is a qualified ‘yes’, i.e. it does not occupy the sparsest level. (shrink)

This paper defends the case against (sparse) disjunctive properties by means of four Armstrongian arguments. The first of these is a logical atomist argument from truthmaking, which is, broadly speaking, ‘Armstrongian’ (Armstrong 1997). This argument is strong – although it stands or falls with the relevant notion of truthmaking, as it were. However, three arguments, which are prima facie independent of truthmaking, can be found explicitly early in Armstrong’s middle period. Two of these early arguments face a serious objection put (...) forward forcefully by Louise Antony (2003) and Alan Penczek (1997), respectively. I consider these objections and argue that they fail. Thus, even if the argument from truthmaking is indecisive, disjunctive properties should be rejected. (shrink)

What I call Mellor’s Question is the problem of whether determinables are properties of their determinates or properties of the particulars that possess these determinates. One can distinguish two basic competing theories of determinables that address the issue, implicitly if not explicitly. On the second-order theory, determinables are second-order properties of determinate properties; on the second-level theory, determinables are first-order properties of the particulars with these determinate properties. Higher-order properties are prima facie ontologically uneconomical, and in line with my general (...) view that ontological parsimony is vital to metaphysics, I consider it highly important which of the two theories is true. Firstly, I argue that the second-level theory offers the best explanation of the explananda (though the race is close), including the important but neglected phenomenon of ‘intermediate determinables’. Secondly, by paying attention to intermediate determinables and instantiation of higher-order properties, I argue that the second-level theory also is more ontologically economical. For these two reasons, this theory is preferable. (shrink)

The theory of truthmaking has long aroused skepticism from philosophers who believe it to be tangled up in contentious ontological commitments and unnecessary theoretical baggage. In this book, Jamin Asay shows why that suspicion is unfounded. Challenging the current orthodoxy that truthmaking's fundamental purpose is to be a tool for explaining why truths are true, Asay revives the conception of truthmaking as fundamentally an exercise in ontology: a means for coordinating one's beliefs about what is true and one's ontological commitments. (...) He goes on to show how truthmaking connects to analyticity, truth, and realism, and how it contributes to debates over nominalism, presentism, mathematical objects, and fictional characters. His book is the most comprehensive exploration to date into what truthmaking is and how it contributes to metaphysical debates across philosophy, and will interest a wide range of readers in metaphysics and beyond.

The strong immanent realism (i.e., the view that there exist universals as entities capable of being wholly present wherever their instances are located) has been traditionally criticized for having certain absurd consequences. Although Gilmore (2003) replied to these criticisms by taking spatial relations involving universals as relativized to their locations, his reply has been rebutted by Keskinen et al. (2015). This paper aims to defend the strong immanent realism by proposing a new version of the relativization strategy, according to which (...) a spatial relation is to be relativized just to the extent that it contains universals or concrete particulars among its terms. This version, it will be argued, can satisfactorily address the objections hitherto posed to the strong immanent realism. (shrink)

In Metaphysics of States of Affairs, Bo Meinertsen reviews and works out several underdeveloped points in the existing scholarly debate on states of affairs, and presents his own original account in detail. In this paper, we raise three problems for Meinertsen’s account and draw attention to an alternative view that, though not discussed in the book, is not beset by these problems.

This précis provides a chapter-by-chapter summary of Metaphysics of States of Affairs (Springer, 2018).

William Vallicella (2020) puts forward three arguments against self-relating internalism, my theory of the unity of states of affairs. His first objection is that there can be no constituent of a state of affairs with the required unifying power given the need for ‘ontological analysis’, or at least that such an entity is mysterious. His second objection is that self-relating internalism violates the principle of the Indiscernibility of Identicals. His final objection is that my explanation of the unity of states (...) of affairs is viciously circular. In this note, I argue that each of challenges can be met. (shrink)

Truth-makers are the dark matter of metaphysics. On the one hand, truth-makers seem obvious and necessary: if there are truths then there must be something that makes these truths true. On the other hand, it’s proven difficult to say exactly what these truth-makers are. Even defenders disagree about what sort of entity truth-makers are or whether all truths have truth-makers. Skeptics have questioned whether truth-makers are actually so obvious and necessary, or even whether they exist at all. Here I offer (...) an account of this unhappy state of affairs and a modest proposal. First, I argue that not only are there no good arguments for truth-makers but it’s unlikely that there ever will be. Second I point to how much can be done without resorting to truth-makers in the first place: they are not as essential as often assumed. Finally, I conclude that we needn’t jettison the concept of truth-makers entirely. Understood in a modest and pragmatic spirit we can hold on to truth-makers while recognizing their inherent limitations. (shrink)

Meinertsen’s unifier is discussed on the background of Aristotle’s distinction between four kinds of unity. It argued that Meinertsen combines two different kinds of unity that exclude each other. Only Aristotle’s first meaning of unity seems to be relevant for Meinertsen’s unifier. But this meaning applies literally only to spatial complexes. Its application to states of affairs is problematic because they are mostly not spatial. It is also problematic because unity in the first sense requires an agent. Meinertsen’s unifiers are (...) connectors between particulars and universals in states of affairs. It is objected that connectors in a state of affairs lead to a vicious infinite regress of further states of affairs. Meinertsen argues for his unifiers that states of affairs without them are non-mereological, that is, their existence is not entailed by the existence of their constituents. That does not seem a good argument if it is realised that a complex is not an additional entity and thus not existent if the existence of its parts is sufficient for its existence. It is also pointed out that the meaning of “mereological” involved is not related to the classical mereological calculus. (shrink)
