For many years there has been a debate in truthmaking theory between proponents of the substantive and deflationary approaches. Substantivists about truthmaking maintain that we need entities called truthmakers, while deflationists of truthmaking argue that the asymmetric form of the T-schema is sufficient. In contrast to incompatibilists, who argue that one should adopt only one of these approaches, I propose a compatibilist theory of truthmaking in which the two approaches complement each other through the distribution of different functions of truthmaking. (...) I find that this helps to solve the problem of truthmaking of certain contentious truths, such as negative truths. (shrink)

The problem of truthmakers for negative propositions was introduced by Bertrand Russell in 1918. Since then the debate has mostly been concerned with whether to accept or reject their existence, and little has been said about what it is that makes a negative proposition negative. This is a problem as it is obvious that you cannot just read it off from the grammar of a sentence. The aim of this paper is to demonstrate that propositions may be negative or positive (...) in many ways: it offers a typology, and shows how the question of the existence of negative facts will receive a different answer depending on its relationship to that typology.

Separatists about grounding take explanations to be separate from their corresponding grounding-facts. Grounding-facts are supposed to underlie, or back, such explanations. However, the backing relation hasn’t received much attention in the literature. The aim of this paper is to provide an informative definition of backing. First, I examine two prominent proposals: backing as explaining (Kovacs 2017; 2019a) and backing as grounding (see Sjölin Wirling 2020). Finally, I put forward my own proposal. I argue that under plausible assumptions about the role (...) of backing and the nature of explanation, backing should be understood as a form of truthmaking, minimally construed. (shrink)

This book proposes a novel theory of truth and falsity. It argues that truth is a form of reference and falsity is a form of reference failure. -/- Most of the philosophical literature on truth concentrates on certain ontological and epistemic problems. This book focuses instead on language. By utilizing the Fregean idea that sentences are singular referring expressions, the author develops novel connections between the philosophical study of truth and falsity and the huge literature in in the philosophy of (...) language on the notion of reference. The first part of the book constructs the author’s theory and argues for it in length. Part II addresses the ways in which the theory relates to, and is different from, some of the basic theories of truth. Part III takes up how to account for the truth of sentences with logical operators and quantifiers. Finally, Part IV discusses the applications and implications of the theory for longstanding problems in philosophy of language, metaphysics, and epistemology. -/- A Referential Theory of Truth and Falsity will appeal to researchers and advanced students working in philosophy of language, epistemology, metaphysics, and linguistics. -/- .

Truth and knowledge are conceptually related and there is a way of construing both that implies that they cannot be solely derived from a description that restricts itself to a set of scientific facts. In the first section of this essay, I analyse truth as a relation between a praxis, ways of knowing, and the world. In the second section, I invoke the third thing—the objective reality on which we triangulate as knowing subjects for the purpose of complex scientific endeavours (...) like medical science and clinical care. Such praxes develop robust methods of “keeping in touch” with disease and illness (like biomarkers). An analysis drawing on philosophical semantics motivates the needed (anti-scientistic) account of meaning and truth (and therefore knowledge) and underpins the following argument: (i) the formulation and dissemination of knowledge rests on language; (ii) language is selective in what it represents in any given situation; (iii) the praxes of a given (sub)culture are based on this selectivity; but (iv) human health and illness involve whole human beings in a human life-world; therefore, (v) medical knowledge should reflectively transcend, where required, biomedical science towards a more inclusive view. Parts three and four argue that a post-structuralist (Lacanian) account of the human subject can avoid both scientism and idealism or unconstrained relativism. (shrink)

2020 update of the entry "Properties".

The notion of fundamentality, as it is used in metaphysics, aims to capture the idea that there is something basic or primitive in the world. This metaphysical notion is related to the vernacular use of “fundamental”, but philosophers have also put forward various technical definitions of the notion. Among the most influential of these is the definition of absolute fundamentality in terms of ontological independence or ungroundedness. Accordingly, the notion of fundamentality is often associated with these two other technical notions.

The subtraction argument aims to show that there is an empty world, in the sense of a possible world with no concrete objects. The argument has been endorsed by several philosophers. I show that there are currently two versions of the argument around, and that only one of them is valid. I then sketch the main problem for the valid version of the argument.

The main scientific problems of chemical bonding were solved half a century ago, but adequate philosophical understanding of chemical combination is yet to be achieved. Chemists routinely use important terms ("element," "atom," "molecule," "substance") with more than one meaning. This can lead to misunderstandings. Eliminativists claim that what seems to be a baseball breaking a window is merely the action of "atoms, acting in concert." They argue that statues, baseballs, and similar macroscopic things "do not exist." When macroscopic objects like (...) baseballs move, exceedingly large numbers (1025) of microscopic components coordinate their activities. Understanding how this happens requires attention to the interactions that link parts into larger units. Eliminativists say that everything that truly exists has causal relationships in addition to those of its components—"nonredundant causality." This paper holds that if a number of entities interact in such a way that the effect of that collection on test objects is different than it would have been in the absence of the interaction, then identification of that collection as a single composite agent is warranted, for purposes to which that difference is relevant. Ordinary "chemical substances" (both elementary materials such as dihydrogen and compounds such as water) fulfill this version of the requirement of nonredundant causality. Other sorts of chemical coherences, including chemical dissipative structures (e.g., flames), also fulfill that criterion. All these types of coherences qualify as "substances" (as that term is used in philosophy) even though they are not all "chemical substances.". (shrink)

In this paper I examine whether the Humean denial of necessary connections between wholly distinct contingent existents poses problems for a theory of tropes. In section one I consider the substance-attribute theory of tropes. I distinguish first between three versions of the non-transferability of a trope from the substratum in which it inheres and then between two versions of the denial of necessary connections. I show that the most plausible combination of these views is consistent. In section two I consider (...) an objection to the bundle theory using the Humean doctrine that is advanced by Armstrong, and argue that it is unconvincing. In section three I return to the version of non-transferability that would cause obvious trouble for a substance-attribute theory, and less obvious trouble for a bundle theory. I argue that there is independent reason to reject this principle since, given a perdurantist metaphysic, it does not in fact secure what appeared to be its only benefit: namely that it allows tropes to act as truthmakers. I conclude that there is no objection to trope theory per se on the grounds that it brings commitment to necessary connections. (shrink)

The present article is the first of a trilogy of papers, devoted to analysing the influence of semantic Platonism on contemporary philosophy of language. In the present article, I lay out the discussion by contrasting semantic Platonism with two other views of linguistic meaning: the socio-environmental conception of meaning and semantic anti-representationalism. Then, I identify six points in which the impregnation of semantic theory with Platonism can be particularly felt, resulting in shortcomings and inaccuracies of various kinds. These points are (...) the following: the limitations of regarding logico-philosophical analysis as the only working methodology; the tendency to avoid investigating a number of aspects of linguistic meaning; the recurring confusion between sentences, statements, and propositions; the weakness of transcendent assumptions about meaning; the weakness of meaning assumptions adopted on the basis of pure intuition; and inconsistencies caused by some over-eager attempts to escape semantic Platonism.

The title of this paper reflects the fact truthmaking is quite frequently considered to be expressive of realism. What this means, exactly, will become clearer in the course of our discussion, but since we are interested in Armstrong’s work on truthmaking in particular, it is natural to start from a brief discussion of how truthmaking and realism appear to be associated in his work. In this paper, special attention is given to the supposed link between truthmaking and realism, but it (...) is argued that this link should not be taken too seriously, as truthmaking turns out to be, to a large extent, ontologically neutral. Some consequences of this are studied. (shrink)

Presentists, who believe that only present objects exist, face a problem concerning truths about the past. Presentists should (but cannot) locate truth-makers for truths about the past. What can presentists say in response? We identify two rival factions ‘upstanding’ and ‘nefarious’ presentists. Upstanding presentists aim to meet the challenge, positing presently existing truth-makers for truths about the past; nefarious presentists aim to shirk their responsibilities, using the language of truth-maker theory but without paying any ontological price. We argue that presentists (...) should be nefarious presentists. (shrink)

Truth pluralists say that there are many ways to be true. Aaron Cotnoir (“Pluralism and Paradox” in: Pedersen and Wright (eds) Truth and pluralism: current debates, Oxford University Press, Oxford, 2013) has suggested a “uniquely pluralist response to the liar”. The basic idea is to maintain that, if a sentence says of itself that it is not true in a certain way, then that sentence is not apt to be true in that way, but is instead apt to be true (...) in a different way. While this is consistent with the basic tenets of truth pluralism, it is an open question whether or not it is amenable to any actual pluralist theory. The primary goal of this paper is to argue that Cotnoir's proposal is amenable to form-based pluralism, rather than domain-based pluralism. In particular, in Section 1, I argue that there are several serious obstacles in the way of the domain-based pluralist who wishes to endorse Cotnoir's proposal; in Section 2, I show how the form-based pluralist can overcome these difficulties. The secondary goal of the paper is to argue that most, if not all, substantivists about truth should find form-based pluralism independently attractive. As such, the possibility of a form-based pluralist solution to the liar is not merely a technical curiosity, but something in which substantivists about truth have a vested interest. (shrink)

Ross Cameron puts forward a novel solution to the truthmaker problem facing presentism. I claim that, by Cameron's own lights, the view is not in fact a presentist view at all, but rather requires us to endorse a form ofPriority Presentism, whereby past objects are derivative and depend for their existence upon present objects. I argue that this view should be rejected.

A fundamental fact is “pure” just in case it has no grounded entities—ex. Tokyo, President Biden, the River Nile, {Socrates}, etc.—among its constituents. Purity is the thesis that every fundamental fact is pure. I argue that Purity is false. My argument begins with a familiar conditional: if Purity is true, then there are no fundamental “grounding facts” or facts about what grounds what. This conditional is accepted by virtually all of Purity’s defenders. However, I argue that it is also the (...) first step toward Purity’s undoing. For, if every grounding fact has a ground, then some grounded entities have “groundmates” or distinct grounded entities that share their full grounds. But, if there are groundmates, then Purity is false. So Purity leads to a contradiction. Therefore, it is false. I close by noting that my argument against Purity also gives us a powerful reason to think that some grounding facts are fundamental. (shrink)

Haecceities are non-qualitative properties for individuation but the current theories about haecceities are still to be much more explored. This paper aims to develop a “haecceity mereology” – that is, an ontological system that understands substances as mereological combinations of haecceities and qualitative properties. In this way, the view developed is an alternative to Paul’s : 578–96; 2006. “Coincidence as Overlap.” Noûs 40 : 623–59) mereological approach. Three rules are proposed: If S is a substance, then there is one and (...) only one haecceity which is S’s qualitative part; For all the fusions with the same haecceity, at most only one of those fusions is a substance; When all the relevant elements are abundant, every element must overlap at least one substance. This is the first ontology of haecceities in the recent literature and would be a model for systematic metaphysics. (shrink)

Monism is a metaphysical view according to which there is only one fundamental object. This paper will explore monism within the context of truthmaker theory, or Truthmaker Monism, a view rarely discussed in literature. Although few truthmaker theorists defend monism, at least explicitly, some theories seem to share the spirit of monism to some extent. Interestingly, they are proposed as solutions for the same problem, called the problem of negative truth. A close examination will show that while each of these (...) solutions can account for the problem, they are unsatisfactory for different reasons. This paper will suggest a novel solution to the problem of negative truth which preserves the advantages of existing solutions while avoiding the difficulties with which they are faced. (shrink)

The book provides a historical and systematic exposition of the semantic theory of truth formulated by Alfred Tarski in the 1930s. This theory became famous very soon and inspired logicians and philosophers. It has two different, but interconnected aspects: formal-logical and philosophical. The book deals with both, but it is intended mostly as a philosophical monograph. It explains Tarski’s motivation and presents discussions about his ideas as well as points out various applications of the semantic theory of truth to philosophical (...) problems. (shrink)

The meanings of utterances and thoughts are commonly regarded in philosophical semantics as abstract objects, called «propositions», which account for how different utterances and thoughts can be synonymous and which constitute the primary truth-bearers. I argue that meanings are instead natural properties that play causal roles in the world, that the kind of «One over Many» thinking underlying the characterization of shared meanings as abstract objects is misguided and that utterances and thoughts having truth-values in virtue of their meanings does (...) not entail that meanings themselves are truth-bearers. (shrink)

Part I of this paper introduced a range of mechanistic theories of causality, including process theories and the complex-systems theories, and some of the problems they face. Part II argues that while there is a decisive case against a purely mechanistic analysis, a viable theory of causality must incorporate mechanisms as an ingredient, and describes one way of providing an analysis of causality which reaps the rewards of the mechanistic approach without succumbing to its pitfalls.

I put forward several desiderata that a philosophical theory of causality should satisfy: it should account for the objectivity of causality, it should underpin formalisms for causal reasoning, it should admit a viable epistemology, it should be able to cope with the great variety of causal claims that are made, and it should be ontologically parsimonious. I argue that Nancy Cartwright’s dispositional account of causality goes part way towards meeting these criteria but is lacking in important respects. I go on (...) to argue that my epistemic account, which ties causal relationships to an agent’s knowledge and ignorance, performs well in the light of the desiderata. Such an account, I claim, is all we require from a theory of causality. (shrink)

This paper examines the relationship between causality and intrinsicality. Construed in one way, that relationship can be defended against some proposed counterexamples. However, I argue that trumping cases pose a more serious, if not fatal, problem. I then examine an alternative way of thinking about the relationship, but suggest that this too meets the same fate.

A fundamental entity is an entity that is ‘ontologically independent’; it does not depend on anything else for its existence or essence. It seems to follow that a fundamental entity is ‘modally free’ in some sense. This assumption, that fundamentality entails modal freedom (or ‘FEMF’ as I shall label the thesis), is used in the service of other arguments in metaphysics. But as I will argue, the road from fundamentality to modal freedom is not so straightforward. The defender of FEMF (...) should provide positive reasons for believing it, especially in light of recent views that are incompatible with it. I examine both direct and indirect routes to FEMF. (shrink)

The present paper addresses Molnar’s problem :72–86, 2000): that of finding positive truthmakers for negative truths. The proposed solution, called, is to hold truth and falsity to be primitive and positive features of propositions and to take every literal negative truth to be made true by the falsity of the atomic proposition that it embeds. The solution is shown to be compatible with Maximalism, Necessitarianism and with the Entailment Thesis, as well as with most if not all possible variants of (...) truthmaking theory. Other advantages of are noted: it doesn’t require the inclusion of exotic objects in one’s ontology; it doesn’t require any revision of one’s logic or of one’s theory of modality. The solution also allows one to eschew negative facts, tropes and properties while providing a definition of negativity for certain literal propositions. The paper ends by rebutting several objections that may be levelled against. (shrink)

Surprisingly, many ethical realists and anti-realists, naturalists and not, all accept some version of the following normative appeal to the natural (NAN): evaluative and normative facts hold solely in virtue of natural facts, where their naturalness is part of what fits them for the job. This paper argues not that NAN is false but that NAN has no adequate non-parochial justification (a justification that relies only on premises which can be accepted by more or less everyone who accepts NAN) to (...) back up this consensus. I show that we cannot establish versions of NAN which are interesting in their own right (and not merely as instances of a general naturalistic ontology) by appealing to the nature of natural properties or the kind of in-virtue-of relation to which NAN refers, plus other plausible nonparochial assumptions. On the way, I distinguish different types of 'in virtue of claims. I conclude by arguing that the way in which assessment of meta-ethical hypotheses is theory-dependent predicts the failure of non-parochial justifications of NAN. (shrink)

Inspired both by our ordinary understanding of the world and by reflection on science, anti-Humeanism is a growing trend in metaphysics. Anti-Humeans reject the Lewisian doctrine of Humean supervenience that the world is “just one little thing and then another”, and argue instead that dispositions, powers, or capacities provide connection and activity in nature. But how exactly are we to understand the shared commitment of this anti-Humean movement? I argue that this kind of anti-Humeanism, at its most general level, is (...) to be understood neither as a view about ontology nor about fundamentality, but rather as a specific claim about what explains what.

Truthmakers, truth conditions, and analyses are closely related, but distinct in rather important ways. A failure to properly appreciate their differences has led to some confusion regarding the role that possible worlds ought to play with respect to modality. Those philosophers who initially proposed the existence of possible worlds were understood as providing an analysis of modality. More recently, many have interpreted them as providing modal truthmakers. But, possible worlds are only suited to serve as truth conditions for modal truths. (...) My goals are as follows: First, to dispel this confusion by detailing the differences between these three concepts. Second, to apply the lesson learned to the famous Humphrey objection against possible worlds. While this objection, if successful, does undermine Lewisian modal realism, it only partially undermines ersatzism, and leaves available a route by which ersatzers may avoid the objection altogether.

Baxter (Australas J Philos 79: 449-464, 2001) proposes an ingenious solution to the problem of instantiation based on his theory of cross-count identity. His idea is that where a particular instantiates a universal it shares an aspect with that universal. Both the particular and the universal are numerically identical with the shared aspect in different counts. Although Baxter does not say exactly what a count is, it appears that he takes ways of counting as mysterious primitives against which different numerical (...) identities are defined. In contrast, I defend the idea— suggested, though not quite endorsed, by Baxter himself—that counts are independent dimensions of numerical identity. Different ways of counting are explained by the existence of these different sorts of identity (i.e., counts). For the instantiation of a universal by a particular, I propose one dimension concerned with the individuation of particulars (the p-count) and another dimension concerned with the individuation of universals (the u-count). On that basis, I give a clear definition of cross-count identity that explains its asymmetrical nature (i.e., the fact that particulars instantiate universais, but not vice versa). I extend the theory to a third dimension—that of time, or the t-count—and thereby defend Baxter's ideas on change, and the contingency of instantiation. Baxter (Mind 97(388): 575-582, 1988; Australas J Philos 79: 449-464, 2001) proposes the related idea of composition as (cross-count) identity. Parts are individually cross-count identical with the wholes that they constitute, and they collectively share all aspects across counts with those wholes. I propose an innovation by which totality is shared distinctness across counts. The theory applies to both the totality of particulars that instantiate any given universal, and the totality of parts that constitute any given whole. I argue that this has several advantages over Armstrong's view, which is based on a dubious external totalling relation. I also argue that Armstrong's theory of numbers (or quantities) as internal relations ought to be rejected in favour of an account based on identity and distinctness. The paper concludes with a careful analysis of external relations in Baxter's framework. I argue that we must recognise one further dimension of identity in order to differentiate between, e.g., the aspects of Abelard insofar as he loves Heloise and Abelard insofar as he loves Isobel. Each of these aspects is identical with Abelard and identical with loving-by, yet they must be in some way distinct. I therefore propose the r-count, in which multiple distinct relational properties are the very same relation (-part). The existence of these four independent dimensions explains the fact that particulars, universals, relations, and times are fundamentally different sorts of things in the ontology. Each is individuated with respect to a different dimension of identity. (shrink)

In this paper I show that a novel ontic reading of explanation, intending to capture the de re essential features of individuals, can support the qualitative view of individual essences. It is argued further that the putative harmful consequences of the Leibniz Principle and its converse for the qualitative view can be avoided, provided that individual essences are not construed in the style of the naïve bundle theory with set-theoretical identity- conditions. Adopting either the more sophisticated two-tier BT or, alternatively, (...) the neo-Aristotelian position of taking essences as natures in the Aristotelian sense, can help to evade these main charges against the qualitative view. The functional parallels with the alternative haecceitistic view of individuation and individual essence will also be considered. (shrink)

Grounding is typically associated to metaphysical explanation on the basis of the explanatory role’s being characteristic of grounding as well. Some even say that all what metaphysical explanation does is tracking the grounding relation. However, recently Maurin has argued that grounding does not “inherit” its properties from metaphysical explanation and, consequently, we should be “separatists”. In this paper separatism will be defended from the perspective of metaphysical explanation thus giving a turn to the separatist strategy. In particular, the structural difference (...) between grounding and metaphysical explanation will be pointed out as affecting also the explanatory function. It will be shown how dispositions and essentialist claims play different roles in the two theories. Lastly, it will be claimed that the two theories diverge on accounting for law-like and accidental generalizations. Provided these arguments are sound, there will be good reason to tell metaphysical explanation apart from grounding. (shrink)

Recently, Choi has argued that current accounts of intrinsically finkable dispositions lead to absurd consequences in certain everyday cases. In this paper I offer a new argument for the existence of intrinsically finkable dispositions, one which provides a new way of testing for the presence of such dispositions. It is then argued that, with this new test in place, Choi’s examples no longer present a problem for the view that some dispositions are intrinsically finkable.

Barker and Smart have argued that dispositional monism is just as susceptible to the ultimate regress problem as Armstrong’s contingent necessitation view of laws. In this response, I consider what implications this conclusion has for the dispositional essentialist project more generally. I argue that it is the monistic aspect of dispositional monism, rather than the dispositional essentialist aspect, which is the source of the problem raised by Barker and Smart. I then outline a version of dispositional essentialism which avoids the (...) ultimate problem by avoiding the commitment to monism. Despite the article by Barker and Smart, it is not time to give up on the dispositionalist project yet. (shrink)

Platonism delivers a theory of possibility that is distinct from both Lewisian modal realism and ersatz modal theories. By putting the topic of alien properties at centre stage in our modal theorizing, a strong preliminary case for platonism can be made. A puzzle about alien properties is created by modern truthmaker theory and some plausible assumptions about properties and existence. But this puzzle is one that platonism is able to solve in a simple and conservative way.

Nomic realists have traditionally put laws to work within a theory of natural modality, in order to provide a metaphysical source for causal necessitation, counterfactuals, and dispositions. However, laws are well-suited to perform other work as well. Necessitation is a widespread phenomenon and includes cases of categorial, conceptual, grounding, mathematical and normative necessitation. A permissive theory of universals allows us to extend nomic realism into these other domains. With a particular focus on grounding necessitation, it is argued that the sorts (...) of reasons for positing laws in the natural causal domain also apply in other domains. Laws might well be the source of all first-order modality. (shrink)

A popular version of anti-Humeanism is one that views fundamental properties as being irreducibly dispositional in nature, and it is a view to which I am attracted. Proponents of this view typically object to Humean regularity theories of laws on the basis that they do not explain why our world is regular rather than chaotic from moment to moment. It is thought that, for this reason, Humeanism does not provide firm enough foundations for induction. However, in this paper I argue (...) that it is far from clear how these anti-Humeans can themselves explain this regularity. This is because it is far from clear how they can explain why the entities in our world do not change their dispositional properties arbitrarily over time. This is a neglected problem, which I call the retention problem. In an attempt to solve this problem, several naturalistic explanations of retention are explored. Unfortunately, none of these explanations is free of problems, showing that dispositional forms of anti-Humeanism may not have as many advantages as some have assumed where the problem of induction is concerned. (shrink)

Necessitarianism, as we shall use the term, is the view that natural properties and causal powers are necessarily connected in some way. In recent decades the most popular forms of necessitarianism have been the anti-Humean powers-based theories of properties, such as dispositional essentialism and the identity theory. These versions of necessitarianism have come under fire in recent years and I believe it is time for necessitarians to develop a new approach. In this paper I identify unexplored ways of positing metaphysically (...) necessary connections in nature, using the concepts of grounding and essential dependence. For example, I show that one could be a necessitarian by insisting that the properties of things necessarily ground their powers, and that one can maintain this while rejecting dispositional essentialism. Using different combinations of claims about grounding and essential dependence, I map out a spectrum of new positions and compare them to previous theories of natural modality. Some of these positions are compatible with Humean metaphysics while others are not. The overall aim of the paper is to provide a new metaphysical framework for understanding theories of powers and thereby launch a new necessitarian research programme. (shrink)

The Platonic account of modality says, roughly, that truths about alien possibilities are grounded in uninstantiated universals. Recently, Ingram has raised a problem for this kind of view, which is that it apparently requires negative facts to play a truthmaking role. Ingram offers an alternative Platonic account which makes use of modal instantiation relations. In this paper, I highlight some of the costs of Ingram’s new account and argue that a more appealing version of Platonism—and modal theory in general—is one (...) that is supplemented with an ontology of totality facts.

Discussion of partial grounds that aren't parts of full grounds; definition of full grounding in terms of partial grounding.

Ostrich presentists maintain that we can use all the expressive resources of the tensed language to provide an explanation of why true claims about the past are true, without thereby paying any price in terms of ontology or basic ideology. I clarify the position by making a distinction between three kinds of explanation, which has general interest and applicability. I then criticize the ostrich position because it requires an unconstrained version of the third form of explanation, which is out of (...) place in metaphysics. (shrink)

Despite the importance of the variational principles of physics, there have been relatively few attempts to consider them for a realistic framework. In addition to the old teleological question, this paper continues the recent discussion regarding the modal involvement of the principle of least action and its relations with the Humean view of the laws of nature. The reality of possible paths in the principle of least action is examined from the perspectives of the contemporary metaphysics of modality and Leibniz's (...) concept of essences or possibles striving for existence. I elaborate a modal interpretation of the principle of least action that replaces a classical representation of a system's motion along a single history in the actual modality by simultaneous motions along an infinite set of all possible histories in the possible modality. This model is based on an intuition that deep ontological connections exist between the possible paths in the principle of least action and possible quantum histories in the Feynman path integral. I interpret the action as a physical measure of the essence of every possible history. Therefore only one actual history has the highest degree of the essence and minimal action. To address the issue of necessity, I assume that the principle of least action has a general physical necessity and lies between the laws of motion with a limited physical necessity and certain laws with a metaphysical necessity.

The aim of this paper is to motivate and then defend a restricted version of the truth-maker theory. In defending such a theory I hope to do away with the perceived need for ‘negative existents’ such as totality facts and the like.

Truths depend upon what there is. So say many. A significant subset of that group say more; they say that the best way—perhaps the only way—to make sense of the claim that truth depends upon what there is, is to adopt a form of truth-maker theory. Truth-maker theorists claim that truths require ground; what’s true must depend upon what there is. Typically, truth-maker theory isn’t seen as a theory about the nature of truth. Rather, it’s seen as a theory about (...) what truths must do. Truths must depend. Relatedly, the claim that truths require ‘truth-makers’, that is, some putative ontological grounds, is used as a methodological tool in metaphysics. Put somewhat crudely, fix on what truths there are and locate the truth-makers—if necessary, add to your ontology until you satisfy this demand for truth-makers. Truth-making is thus at once both narrow and broad. It’s narrow insofar as it’s not a theory (it’s not a claim) about the nature of truth, and yet it’s broad insofar as it enables us to determine our ontological commitments. We take this to be a two-part orthodoxy about truth-making. We reject the orthodoxy on both counts. (shrink)
