Truthmakers

Adrian Heathcote has proposed a truth-making account of knowledge that combines traditional conditions of justified true belief with the truth-making condition, which would jointly provide us with the sufficient condition of knowledge, and this truth-maker account of knowledge in turn explains why a gettiered justified true belief fails to be regarded as a genuine instance of knowledge. In this paper, by the comparison of two different casual models that are illustrated by the thermometer and the clock respectively, however, it will (...) be argued that Heathcote’s truth-making account of knowledge fails to cope with the Gettier case of the stopped clock and therefore is called for some further remedy.

It seems that the most common strategy to solve the liar paradox is to argue that liar sentences are meaningless and, consequently, truth-valueless. The other main option that has grown in recent years is the dialetheist view that treats liar sentences as meaningful, truth-apt and true. In this paper I will offer a new approach that does not belong in either camp. I hope to show that liar sentences can be interpreted as meaningful, truth-apt and false, but without engendering any (...) contradiction. This seemingly impossible task can be accomplished once the semantic structure of the liar sentence is unpacked by a quantified analysis. The paper will be divided in two sections. In the first section, I present the independent reasons that motivate the quantificational strategy and how it works in the liar sentence. In the second section, I explain how this quantificational analysis allows us to explain the truth teller sentence and a counter-example advanced against truthmaker maximalism, and deal with some potential objections.

The thesis aims to account for the pre-theoretic intuition of asymmetric dependence between truth and reality, namely, the intuition that truth depends on reality, but reality doesn’t depend on truth. I start by delineating a framework to answer this question: according to this framework, a proper theory of dependence asymmetry should explain why truth depends on reality (truth-reality dependence) and why reality doesn’t depend on truth (asymmetry). There are two readings of the second requirement: a strong reading and a weak (...) reading. According to the strong reading, if a theory can offer a positive explanation for (truth-reality dependence) but not (asymmetry), then it is not a proper theory of dependence asymmetry. According to the weak reading, a proper theory of dependence asymmetry should, at least, offer a positive explanation for (truth-reality dependence). In addition, if there are two theories that can do that, then the one which can also provide a positive explanation for (asymmetry) is a better theory. With its research framework, the thesis explores existing theories of dependence asymmetry in the literature. Based on whether a theory accepts a genuine dependence relation between truth and reality or not, existing theories are divided into two groups (N group and Y group). The N group includes the conceptual account and the semantic mechanism account. Both accounts in the N group deny a genuine dependence relation between truth and reality. They differ in how they explain away the need for a dependence relation. The conceptual account (Dodd 2007; Schnieder 2006b) offers a conceptual explanation for dependence asymmetry: the intuition of asymmetric dependence is considered to be a result of an asymmetry on the conceptual level. The thesis raises an objection to the conceptual account: the conceptual account is problematic because it mistakes metaphysical dependence for conceptual dependence. The dependence asymmetry is about the former instead of the latter. The semantic mechanism account (Audi 2020; MacBride 2014) appeals to the semantic mechanism to explain the dependence asymmetry. Although the semantic mechanism account can explain truth’s dependence on reality, it cannot offer a positive explanation for the asymmetric characteristic of the dependence. In other words, it cannot explain why reality doesn’t depend on truth. In contrast to theories in the N group, theories in the Y group accept a genuine dependence relation between truth and reality. There are three accounts in the Y group: the supervenience account, the truth-maker theory, and the grounding account. The supervenience account (Lewis 2001) appeals to the notion of supervenience to explain the dependence asymmetry. However, due to its non-symmetric characteristic, supervenience cannot explain why reality doesn’t depend on truth. Hence, an asymmetric relation is required. As for the truth-maker theory, whether it can explain the dependence asymmetry depends on how the notion of truth-maker (and accordingly the notion of truthmaking) is defined. The thesis considers five main definitions of a truth-maker in the literature and concludes that it’s most plausible to consider truthmaking as a kind of grounding relation (Griffith 2014; Asay 2017; Rodriguez-Pereyra 2015). In this way, truthmaking as grounding is the best candidate for a theory of dependence asymmetry. The study of the existing theories tells us that an account that appeals to an asymmetric relation and offers a positive explanation for (asymmetry) can best capture the dependence asymmetry. Hence, the thesis proposes the grounding-representation account, which is a modified version of Schaffer’s account of truthmaking (Schaffer 2010). According to the grounding-representation account, truthmaking is a specific kind of grounding relation with its specific generation form, which is representation: a true proposition represents the relevant portion of reality. With the asymmetric characteristic of grounding, the account can offer a positive explanation for (asymmetry). Consequently, the thesis concludes that the grounding-representation account is the best theory of dependence asymmetry. (shrink)

_ Source: _Page Count 25 The familiar challenges to historiographical knowledge turn on epistemological concerns having to do with the unobservability of historical events, or with the problem of establishing a sufficiently strong inferential connection between evidence and the historiographical claim one wishes to convert from a true belief into knowledge. This paper argues that these challenges miss a deeper problem, viz., the lack of obvious truth-makers for historiographical claims. The metaphysical challenge to historiography is that reality does not appear (...) to co-operate in our cognitive endeavours by providing truth-makers for claims about historical entities and events. Setting out this less familiar, but more fundamental, challenge to the very possibility of historiography is the first aim of this paper. The various ways in which this challenge might be met are then set out, including ontologically inflationary appeals to abstract objects of various kinds, or to “block” theories of time. The paper closes with the articulation of an ontologically parsimonious solution to the metaphysical challenge to historiography. The cost of this approach is a revision to standard theories of truth. The central claim here is that the standard theories of truth have mistaken distinct causes of truth for truth itself. This mistake leads to distorted expectations regarding truth-makers for historiographical claims. The truth-makers of historiographical claims are not so much the historical events themselves but atemporal modal facts about the order of things of which those events were a part. (shrink)

A recent presentist strategy has been to deny that truths about the past need presently existing truthmakers. These presentists do not deny that such truths need grounding; they hold that each truth about the past is true because of how the world was, not how it is. This paper argues that this position faces two problems, one of which can be overcome by adopting a certain view of the property of truth for propositions about the past. The second problem cannot (...) be solved. The upshot is that this form of presentism is not a theory of truthmaking for propositions about the past. Rather, it is a theory about why such truths need no present grounding that is motivated by a novel theory of truth. (shrink)

In this review I take to task the related views of E.J. Lowe, John Heil and Peter Simons according to which relations don't exist because they're dispensable qua truth-makers. I argue that this view is methodologically unstable because we also have reason to believe that relations exist because our best mathematical and scientific theories say so, i.e. quantify over them.

One of the core issues where interpreters of Kant disagree is with regards to Kant’s alleged Noumenalism: the claim that the objects of our experience, which are in space and time, are underpinned by entities that are not spatio-temporal, and which non-spatio-temporally cause our representations of empirical objects. Although there is much textual evidence in favour of Noumenalism, non-Noumenalists have also gathered a significant number of philosophical and exegetical challenges to such a reading of Kant. I present a novel way (...) of understanding the Noumenalist view, which characterizes the distinction between appearances and things in themselves as the distinction between referents and truthmakers. After fleshing out this distinction, I show that, on this interpretation of Kant, the most pressing problems for the Noumenalist reading are primarily based on equivocations between features of reference and features of truthmaking.

Presentists hold that only present things exist. But we all, presentists included, utter sentences that appear to involve quantification over non-present objects, and so we all, presentists included, seem to commit ourselves to such objects. Equally, we all, presentists included, take utterances of many past-tensed (and some future-tensed) sentences to be true. But if no past or future things exist, it’s hard to see how there can be anything that those utterances are about, which makes them true. This paper presents (...) a hitherto unexplored response to both problems: pretence fictionalism about the non-present. This view combines semantic factualism with psychological non-cognitivism. Sentences that appear to quantify over the non-present have propositional content and (almost all of) those propositions are false because the thing they are about—the non-present—does not exist. Nevertheless when we utter such sentences we don’t thereby utter something false. Our utterances do not report the belief that the propositional content of the sentence uttered is true; rather, they express a non-cognitive attitude towards that content: namely an attitude of pretence. Hence by thinking various thoughts, and uttering various sentences we are, collectively, pretending as though things were (or will be) thus and so. (shrink)

In this paper I deal with the relation between the disjunction thesis—that the truthmaking relation is distributed over a disjunction—and the necessary connection thesis—that the existence of some entities requires the existence of other distinct entities. I will first show that because of this very relation, the arguments for and against the disjunction thesis that overlook its metaphysical considerations will fail. Finally, I will show that the commitment produced by truthmaker maximalism to totality states of affairs, or some relevantly similar (...) things, requires one to accept a necessary connection that disaffirms the disjunction thesis. (shrink)

In this paper I argue against the traditional view that truth-making distributes over entailment and present a novel account that takes truth-making to distribute over grounding between the existence of facts, thereby avoiding the shortcomings of the traditional view.

This paper is inspired by and develops on E. J. Lowe’s work, who writes in his book The Possibility of Metaphysics that ‘metaphysical possibility is an inescapable determinant of actuality’ (1998: 9). Metaphysics deals with possibilities – metaphysical possibilities – but is not able to determine what is actual without the help of empirical research. Accordingly, a delimitation of the space of possibilities is required. The resulting – controversial – picture is that we generally need to know whether something is (...) possible before we can know whether it is actual. In order to appreciate this picture, we need to understand Lowe’s slogan: ‘essence precedes existence’ (Lowe 2008: 40). This slogan has both an ontological and an epistemic reading. The ontological reading is related to the now familiar idea that essence grounds modality, as popularised by Kit Fine. The epistemic reading suggests that we can know the essence of some entity before we know whether or not that entity exists. However, this idea is often met with puzzlement and Lowe himself sadly passed away before he had a chance to clarify this framework. I will present the framework as I understand it, develop it on my own terms, and put forward a qualified defence of it. I will also illustrate how the framework can be put to use with a case study concerning the discovery of transuranic elements. (shrink)

We construct a presentist semantics on which there are no truth-makers for past and future tensed statements. The semantics is not an expressivist or projectivist one, and is not susceptible to the semantical difficulties that confront such theories. We discuss how the approach handles some standard concerns with presentism.

Derek Parfit defended Non-Realist Cognitivism. It is an open secret that this metaethical theory is often thought at best puzzling and at worst objectionably unclear. Employing truthmaker theory, I provide an account of Non-Realist Cognitivism that dispels charges of objectionable unclarity, clarifies how to assess it, and explains why, if plausible, it would be an attractive theory. I develop concerns that the theory involves cheating into an objection that ultimately reveals Non-Realist Cognitivism faces a dilemma. Whether it can escape demands (...) further attention. In bridging metaethics and the truthmaking literature, I illustrate the importance of greater meta-metaphysical reflection in metaethics. (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. I argue in A Theory of Truthmaking that this suspicion is unfounded. Philosophers across the spectrum can take advantage of truthmaking, and use it to better understand the ontological implications of topics that arise all over the philosophical landscape. Challenging the current orthodoxy that truthmaking's fundamental purpose is to be a tool for explaining why truths (...) are true, the book 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. I go 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. (shrink)

Hossack's 'The Metaphysics of Knowledge' develops a theory of facts, entities in which universals are combined with universals or particulars, as the foundation of his metaphysics. While Hossack argues at length that there must be negative facts, facts in which the universal 'negation' is combined with universals or particulars, his conclusion that there are also general facts, facts in which the universal 'generality' is combined with universals, is reached rather more swiftly. In this paper I present Hossack with three arguments (...) for his conclusion. They all draw, as does Hossack's theory of facts, on views Russell expressed in various writings. Two arguments are based on Russell's explanation of universals as aspects of resemblance; the third on Russell's observation that general propositions do not follow logically from exclusively particular premises. Comparison with other metaphysics of generality show them to be wanting and Russell's and Hossack's accounts superior. (shrink)

Most theories of causation assume that it must involve some kind of necessity, or that the cause must be entirely sufficient for the effect. Others have already suggested that it should be possible to get a theory of causation from a theory of powers or dispositions. Such a project is far from complete but even here we find that the key point in a dispositional theory of causation has been lacking. This paper attempts to establish some of the most important (...) principles of such a theory and in so doing turn the existing discussion in a new direction. (shrink)

I argue that deflationary theories of truth reveal an important lesson for the broader theory of truth: although the notion of truthmaking has played an essential role in many traditional theories of truth, it can be separated from and survive the rejection of substantive theories of truth. I argue that many of the traditional substantive theories of truth are unified in defining truth in terms of the ontological grounds that are needed to account for truth. Deflationists reject the idea that (...) a theory of truth needs such metaphysical implications, but in so doing they need not rule out the possibility of developing an independently motivated theory of truthmaking. I argue that deflationists can and should embrace truthmaker theory, once it is shorn from its connection to the traditional project of defining truth. (shrink)

Review of Jamin Asay: A theory of truthmaking. Metaphysics, ontology, reality. Cambridge: Cambridge University Press, 2020.

Although the doctrine of divine simplicity has faced substantial criticism in recent years, Jeffrey Brower has recently offered a novel defense of the view by appealing to contemporary truthmaker theory. In this paper, I will argue that Brower’s defense of divine simplicity requires an implausible account of how truthmaking works for essential intrinsic predications. I will first argue that, unless Brower is willing to make an ad hoc exception for how truthmaking works in God’s case, he is committed to saying (...) that essential intrinsic predications about any object are made true by that object alone, not by its having essential properties. I will then argue that reflecting on cases where distinct essential intrinsic predications about an object have different causal explanations behind them shows that this general view of truthmaking is implausible.

In his 1918 logical atomism lectures, Russell argued that there are no molecular facts. But he posed a problem for anyone wanting to avoid molecular facts: we need truth-makers for generalizations of molecular formulas, but such truth-makers seem to be both unavoidable and to have an abominably molecular character. Call this the problem of generalized molecular formulas. I clarify the problem here by distinguishing two kinds of generalized molecular formula: incompletely generalized molecular formulas and completely generalized molecular formulas. I next (...) argue that, if empty worlds are logically possible, then the model-theoretic and truth-functional considerations that are usually given address the problem posed by the first kind of formula, but not the problem posed by the second kind. I then show that Russell’s commitments in 1918 provide an answer to the problem of completely generalized molecular formulas: some truth-makers will be non-atomic facts that have no constituents. This shows that the neo-logical atomist goal of defending the principle of atomicity—the principle that only atomic facts are truth-makers—is not realizable. (shrink)

This paper aims to support the claim that analytic metaphysics should be more cautious regarding the constraints that truthmaking considerations impose on metaphysical theories. To this end, I reply to Briggs and Forbes (2017), whoargue that certain truthmaking commitments are incurred by a Humean metaphysics and by the Growing-Block theory. First, I argue that Humean Supervenience does not need to endorse a standard version of truthmaker maximalism. This undermines Briggs and Forbes’s conclusion that Humean Supervenience and the Growing-Block theory are (...) incompatible. Second, I argue that the Growing-Block theory does not commit us to any weaker version of truthmaker maximalism, which also undermines Briggs and Forbes’s conclusion. Finally, I point out other reasons to think that any version of truthmaker maximalism is disputable, undermining a fortiori Briggs and Forbes’s conclusion and supporting the moral that metaphysical theories—or at least Humean Supervenience, the Growing-Block theory, and presentism—are little constrained by truthmaking commitments.

I provide and defend a hyper-intensional account of verisimilitude within the truthmaker framework.

Presentism faces the following well-known dilemma: either the truth-value of past-tense claims depends on the non-existing past and cannot be said to supevene on being, or it supervenes on present reality and breaks our intuition which says that the true past-tense claims should not depend on any present aspect of reality. The paper shows that the solution to the dilemma offered by Kierland and Monton’s brute past presentism, the version of presentism according to which the past is supposed to be (...) both a fundamental and present aspect of reality, is implausible and proposes how to cure presentism: the dillema can be avoided by taking a third road consisting of introducing dynamics into presentism in the form of the real passage of time. Dynamic presentism, which is constructed in such a way, can overcome the dilemma by providing an ontological basis for the past-tense propositions in the form of the real past. Dynamic presentism also offers a rationale for treating the future as being open. (shrink)

Jago uses a Fitch-style argument in an attempt to demonstrate that every truth has a truthmaker. But Trueman shows that there is a parallel argument, this time to the conclusion that no truth has a truthmaker. Since we cannot accept both, we must ditch at least one Fitch. But which? Keywords: Truth, truthmaking, truthmaker maximalism, Fitch paradox, Robert Trueman.

This paper first identifies several plausible desiderata on satisfactory explanations of logical theorems, shows that ordinary grounding explanations cannot satisfy them and argues that there is reason to believe that no alternative grounding explanations of logical theorems can be given. It then develops an alternative explanation of logical theorems based on Yablo’s idea of reductive truthmaking. The resulting proposal invokes instances of reductive truthmaking that bear an interesting structural similarity to the notion of zero-ground, in virtue of which it is (...) able to satisfy the identified desiderata. (shrink)

I present an argument proving that there are no fundamental facts, which is similar to an argument recently presented by Mark Jago for truthmaker maximalism. I suggest that this argument gives us at least some prima facie, defeasible reason to believe that there are no fundamental facts.

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)

Jago and Loss have recently used variations on Fitch's paradox to argue that every truth has a truthmaker, and that every fact is grounded. In this paper, I show that Fitch's paradox can also be adapted to prove the exact opposite conclusions: no truth has a truthmaker, and no fact is grounded. All of these arguments are as dialectically effective as each other, and so they are all in bad company.

Meinertsen has recently put forward three arguments against disjunctive properties: the arguments from truthmaking, commonality, and causation. In this paper, I argue that all three arguments fail. The argument from truthmaking rests on the problematic notion of different types of truthmakers and is therefore itself problematic. The argument from commonality may hold but only at the cost of losing much of the philosophical significance of its conclusion. The argument from causation essentially collapses into the argument from truthmaking and is therefore (...) problematic for the same reason as the latter is. I conclude that Meinertsen has not made a case against disjunctive properties. (shrink)

Presentism is one of the various views in the discourse on the existence of time and spatio-temporal reality which holds that only the present is real and also that only present things exist. Neil McKinnon characterizes presentism in some ways that are all problematic, although he claims that the most appealing of all is the statement that “only present entities exist.” This view permeates all thoughts about presentism, and it has led to problems about the formulation of presentism. The link (...) between accepting the existence of a temporal part and the events that have that part as its spatio-temporal reference creates a hub of debate among presentists, and this raises a lot of issues not just in metaphysics, but in other areas of philosophical discourse as well. Tallant and Ingram take a challenging position on this issue as presentists in their own right. For them, the requisite status of a presentist properly so-called should be of a commitment to the reality of the present exclusively. In this paper, I engage the views of Tallant and Ingram on the problems of presentism such as triviality and truthmaking as regards ontological implications. I will argue that the avoidance of ontological commitment in nefarious presentism does appear to avoid the problem of truthmaking, which implies avoiding an analysis of truth in order to solve the problem of truthmaking. I will also argue that this avoidance to address the principle of un-analyzability of thisness is a recourse to primitivism. (shrink)

This paper introduces a new kind of explanation that we describe as ‘purely theoretical’. We first present an example, E, of what we take to be a case of purely theoretical explanation. We then show that the explanation we have in mind does not fit neatly into any of the existing categories of explanation. We take this to give us prima facie motivation for thinking that purely theoretical explanation is a distinctive kind of explanation. We then argue that it can (...) earn its keep via application to two existing literatures: the literature on how we explain the truth of true negative existential propositions and the literature on how we explain the truth of true propositions about the past. We reply to some possible concerns regarding the introduction of purely theoretical explanations. We conclude that there is nothing obviously wrong with them and explore the ramifications for particular debates in metaphysics. (shrink)

Many philosophers think truthmaker theory offers a correspondence theory of truth. Despite the similarities, however, this identification cannot be correct. Truthmaker theory offers no theory of truth, nor can it be employed to offer an acceptable substantive theory of truth. Instead, truthmaker theory takes truth for granted. Though truthmaker theory is not a correspondence theory, it shares with it the same motivational basis—that truth is worldly—and better accounts for what is pre-theoretically compelling about correspondence theories. As a result, those at (...) all attracted to correspondence theory (including many deflationists) should reject it and accept truthmaker theory instead. (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.

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.

A common account of the distinction between analytic and synthetic truths is that while the former are true solely in virtue of meaning, the latter are true also in virtue of the way of the world. Quine famously disputed this characterization, and his skepticism over the analytic/synthetic distinction has cast a long shadow. Against this skepticism, I argue that the common account comes close to the truth, and that truthmaker theory in particular offers the resources for providing a compelling account (...) of the distinction that preserves the basic ideas behind it, and avoids the standard criticisms facing the distinction. In particular, I argue that analytic truths are truths that ontologically depend in no way whatsoever upon what exists. (shrink)

In this paper we confront a challenge to truthmaker theory that is analogous to the objections raised by deflationists against substantive theories of truth. Several critics of truthmaker theory espouse a ‘deflationary’ attitude about truthmaking, though it has not been clearly presented as such. Our goal is to articulate and then object to the underlying rationale behind deflationary truthmaking. We begin by developing the analogy between deflationary truth and deflationary truthmaking, and then show how the latter can be found in (...) the work of Dodd, Hornsby, Schnieder, Williamson, and others. These philosophers believe that the ambitions of truthmaker theory are easily satisfied, without recourse to ambitious ontological investigation—hence the analogy with deflationary truth. We argue that the deflationists’ agenda fails: there is no coherent deflationary theory of truthmaking. Truthmaking, once deflated, fails to address the questions at the heart of truthmaking investigation. Truthmaking cannot be had on the cheap. (shrink)

According to truthmaker maximalism, each truth has a truthmaker. Peter Milne has attempted to refute truthmaker maximalism on mere logical grounds via the construction of a self-referential truthmaker sentence M “saying” of itself that it doesn’t have a truthmaker. Milne argues that M turns out to be a true sentence without a truthmaker and thus provides a counterexample to truthmaker maximalism. In this paper, I show that Milne’s refutation of truthmaker maximalism does not succeed. In particular, I argue that the (...) notion of truthmaker meets two structural principles which, if added to a formal language of a theory, are already sufficient to produce a provable contradiction—a contradiction that gives rise to a socalled “Truthmaker paradox”. I also address the question of how to possibly resolve the Truthmaker paradox. I thereby show that the Truthmaker paradox, just as the strengthened Liar paradox, yields a “revenge problem” for paracomplete theories and might lead to triviality for Priest’s dialetheist account LP if the notion of truthmaker is defined as a certain semantic predicate within LP. But regardless of how one tries to cope with the Truthmaker paradox, this paradox is surely interesting in its own right. However, its significance is completely orthogonal to the question of whether truthmaker maximalism is a philosophically sound view. (shrink)

A natural proposal for the grounds of negative existential truths, such as that Vulcan does not exist, states that these truths are grounded in the totality truth affirming the existence of every existent thing together with the truth that they are all. In this paper I will put forward three objections to straightforward formulations of this idea, and argue that a change in the usual grammar of grounding claims, allowing for pluralities of sentences to express not only grounds, but also (...) groundees, is effective in making the account immune to the objections raised. (shrink)

I argue that counterpart theory is incompatible with truthmaking supervenience, the thesis that truth supervenes on what there is and how things are. I further argue that David Lewis’s “qua” strategy for providing ontologically innocent and Humean-friendly truthmakers for predications faces a number of difficulties. I propose and assess various solutions to those difficulties, each of which comes at the cost of sacrificing one of the two main virtues of the qua strategy.

We aim to compile some means for a rational reconstruction of a named part of the start-over of Baruch (Benedictus) de Spinoza's metaphysics in 'de deo' (which is 'pars prima' of the 'ethica, ordine geometrico demonstrata' ) in terms of 1st order model theory. In so far, as our approach will be judged successful, it may, besides providing some help in understanding Spinoza, also contribute to the discussion of some or other philosophical evergreen, e.g. 'ontological commitment'. For this text we (...) assume the reader familiar with 'de deo' as well as with some basic concepts and results of 1st order model theory. Before we start reconstruction, we will first revisit shortly the concept of 'attributum' (definitio IV) in it's setting in 'de deo' , next scan for formalizable aspects of 'in suo genere finita' ('de deo', definitio II), subsequently list the model theoretic constructs we will make use of. Then we begin reconstruction by stating "coordinative definitions" for the notions of 'attribute (of a substance)', 'modus (as conceived via an attribute)' and 'substance (as conceived via an attribute)', reasoning shortly for each of them. The "coordinative definitions", we will arrive at, must not be understood as literal translations of Spinoza's concepts - of course, there can't be such a thing as a literal translation - they are meant as formal analoga of these concepts, mapping some logical structure. But even with this caveat they may seem strange to the reader at this stage of discussion. Additional justification for them then should be found in our endeavour, to map some argumentation of Spinoza's proofs of some of his propositions from this starting point. -/- [ Version 1 of this paper originated from 2020-03-14.

The purpose of this paper is to communicate - as a proposal - a general method of assigning a 'truthmaker' to any 1st order sentence in each of its models. The respective construct is derived from the standard model theoretic (recursive) satisfaction definition for 1st order languages and is a conservative extension thereof. The heuristics of the proposal (which has been somewhat idiosyncratic from the current point of view) and some more technical detail of the construction may be found in (...) my article on part I of Spinoza's `ethica, ordine geometrico demonstrata', which is the context within which I elaborated the assignment. But this context need not be repeated here, the presentation of the truthmaker assignment will be comprehensible to anybody with solid basic knowledge in 1st order model theory, anything used is standard and no advanced techniques are required.

Each truth has a truthmaker: an entity in virtue of whose existence that truth is true. So say truthmaker maximalists. Arguments for maximalism are hard to find, whereas those against are legion. Most accept that maximalism comes at a significant cost, which many judge to be too high. The scales would seem to be balanced against maximalism. Yet, as I show here, maximalism can be derived from an acceptable premise which many will pre-theoretically accept.

Philosophical discussion of truthmaking has flourished in recent times, but what exactly does it mean to ‘make’ a truth-bearer true? I argue that ‘making’ is a concept with modal force, and this renders it a problematic deployment for truthmaker theorists with nominalist sympathies, which characterises most current theories. I sketch the outlines of what I argue is a more genuinely realist truthmaker theory, which is capable of answering the explanatory question: In virtue of what does each particular truthmaker make its (...) particular truthbearer true? I do this by drawing on recent work by Frederik Stjernfelt on Charles Peirce’s account of the proposition as having a ‘particular double structure’, according to which a proposition not only depicts certain characters of an object, it also depicts itself claiming those characters to pertain to the object. This double structure, I shall argue, also resolves important issues in analytic philosophers’ truthmaker theory, including the proper distinction between reference and truthmaking, and a dilemma concerning an infinite regress of truthmaking.

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)

This paper gives an outline of truthmaker semantics for natural language against the background of standard possible-worlds semantics. It develops a truthmaker semantics for attitude reports and deontic modals based on an ontology of attitudinal and modal objects and on a semantic function of clauses as predicates of such objects. It also présents new motivations for 'object-based truthmaker semantics' from intensional transitive verbs such as ‘need’, ‘look for’, ‘own’, and ‘buy’ and gives an outline of their semantics. This paper is (...) a commissioned 'target' article, with commentaries by W. Davis, B. Arsenijevic, K. Moulton, K. Liefke, M. Kaufmann, R. Matthews, P. Portner and A. Rubinstein, P. Elliott, G.

In this paper, I both propose and discuss a novel account of truthmaking. I begin by showing what truthmaking is not: it is not grounding and it is not correspondence. I then show what truthmaking is by offering an account that appeals both to grounding and what I call ‘deep correspondence’. After I present the account and show that it is an account that unifies, I put it to work by showing how it can overcome an objection to truthmaking, how (...) we can get truthmaking from correspondence, what it says about truthmaker necessitation, and how it can explain a connection between truthmaker maximalism and pluralism about truth.

Truthmaker theory has been used to argue for substantial conclusions about the categorial structure of the world, in particular that states of affairs are needed to play the role of truthmakers. In this paper, I argue that closely considering the role of aboutness in truthmaking, that is considering what truthbearers are about, yields the result that there is no good truthmaker-based reason to think that truthmakers must be states of affairs understood as existing entities, whether complex or simple. First, I (...) introduce an aboutness-based account of truthmaking as a metaphysically modest alternative to the orthodox necessitarian account of truthmaking. Second, I discuss the distinction between states and events that has been made on the basis of linguistic evidence regarding aspectual markers and nominalisation. I argue that the modest approach to truthmaking allows us to accept that there is a real distinction between states and events without requiring that the distinction is ontologically substantial. Specifically, what we are talking about with state-truthbearers really differs from what we are talking about with event-truthbearers, but this difference need not be understood as a difference in kinds of entities. Because of its overall modesty, this is a theoretically virtuous result. (shrink)
