Meta-ethical realism faces the serious epistemological problem of how to explain our epistemic access to moral reality. In the face of this challenge many are sceptical about non-naturalist realism. Nonetheless, there is good reason to acknowledge moral objectivity: morality shows all the signs of a truth-apt discourse but doesn’t exhibit the typical relativity inducing features. This suggests a middle-ground position, a theory that embraces the virtues of realism but does avoid its vices: objectivist antirealism. In this paper, I’ll discuss, mainly (...) following Crispin Wright’s account of moral truth as superassertibility, a promising version of objectivist antirealism and show how to cope with notorious problems, notably those arising from the thought that moral disagreement might be possible in which nobody is guilty of a cognitive shortcoming, which contradicts the antirealist claim that moral truth is not beyond our epistemic reach. The solution is to deny the possibility of cognitively faultless moral disagreement by arguing that cognitively blameless thinkers either agree or stay agnostic and, therefore, never disagree about any moral proposition. Since assuming an agnostic stance on the part of such thinkers contradicts the antirealist’s conception of truth—even within the limits of intuitionistic logic—I’ll propose an alternative logical revision for the moral discourse: a three-valued logic with epistemically construed truth-values.

I have two objectives in this paper. The first is to investigate whether, and to what extent, truth is valuable. I do this by first isolating the value question from other normative questions. Second, I import into the debate about the nature of truth some key distinctions hailing from value theory. This will help us to clarify the sense in which truth is valuable. I then argue that there is significant variability in the value of truth in different areas of (...) discourse. I shall call this the axiological variability conjecture. I illustrate and substantiate AVC by contrasting the occurrence of disagreement in two paradigmatically evaluative areas of discourse, viz. matters of taste, on the one hand, and morality, on the other. I claim that there is a reasonable tendency to care much more about settling moral disagreements than taste disagreements and that this difference has to do, at least partly but significantly, with the different value that truth exhibits in these two areas of discourse. I then turn to the second objective of the paper—namely, to discuss how pluralistic accounts of the nature of truth may deal with the value of truth in light of AVC. I will argue that AVC is a problem for all versions of truth pluralism that are committed to the following two theses: that truth is a value concept; and that this characteristic of the concept has to be reflected in the metaphysical nature of any admissible truth properties—i.e., all the various properties that are admissible in the pluralist account are value-conferring properties and thus intrinsically valuable. In so doing, I will focus primarily on Michael Lynch’s functionalist incarnation of truth pluralism. Lynch terms this “Manifestation Alethic Pluralism”. My reason for this is twofold: first and foremost, MAP is a paradigmatic exemplification of a model of truth pluralism that is committed to both and ; second, MAP has, to date, enjoyed the most discussion, and currently provides the most developed account of truth pluralism. However, I argue that MAP lacks the resources to account for AVC. Owing to this, I suggest two ways out for an advocate of MAP, which force various structural changes in her view. (shrink)

We are logical pluralists who hold that the right logic is dependent on the domain of investigation; different logics for different mathematical theories. The purpose of this article is to explore the ramifications for our pluralism concerning normativity. Is there any normative role for logic, once we give up its universality? We discuss Florian Steingerger’s “Frege and Carnap on the Normativity of Logic” as a source for possible types of normativity, and then turn to our own proposal, which postulates that (...) various logics are constitutive for thought within particular practices, but none are constitutive for thought as such.

Relativists make room for the possibility of “faultless disagreement” by positing the existence of subjective propositions, i.e. propositions true from some points of view and not others. We discuss whether the adoption of this position with respect to a certain domain of discourse is compatible with a realist attitude towards the matters arising in that domain. At first glance, the combination of relativism and realism leads to an unattractive metaphysical picture on which reality comprises incoherent facts. We will sketch the (...) contours of a realist-relativist position called “subjectivism”, which avoids this result by giving up the assumption that the points of view of different subjects are all metaphysically “on a par”.

Penelope Maddy has recently addressed the set-theoretic multiverse, and expressed reservations on its status and merits ([Maddy, 2017]). The purpose of the paper is to examine her concerns, by using the interpretative framework of set-theoretic naturalism. I first distinguish three main forms of 'multiversism', and then I proceed to analyse Maddy's concerns. Among other things, I take into account salient aspects of multiverse-related mathematics , in particular, research programmes in set theory for which the use of the multiverse seems to (...) be crucial, and show how one may provide responses to Maddy's concerns based on a careful analysis of 'multiverse practice'.

It is possible to construct situations (with a suitable kind of setting) in which one speaker utters ‘This is tasty’ and another speaker responds with ‘That’s not true’. The aim of this paper is to motivate the idea that typical (broadly) expressivist accounts of taste disagreements are not in a position to explain such situations (although some of them can successfully explain disagreements in which another kind of dissent phrase—like ‘Nuh-uh’—is employed). This is because utterances of ‘That’s not true’ are (...) typically used to ascribe falsehood to propositions. Taste expressivism has it, however, that when one utters ‘This is tasty’, one typically manifests her evaluative attitude (which is non-propositional) toward something rather than describes what attitude she bears toward the thing. Another aim of the paper consists in proposing an alternative account of taste disagreements. It is close to taste expressivism when it comes to the explanation of disagreements in which speakers respond with ‘Nuh-uh’ to utterances of ‘This is tasty’, but departs from it in situations in which they respond with ‘That’s not true’. The account is developed within a contextualist framework according to which taste utterances express contextually enriched propositions that contain judges who evaluate things as tasty or not.

Recently, companions in guilt strategies have garnered significant philosophical attention as a response to arguments for moral error theory, the view that there are no moral facts and that our moral beliefs are thus systematically mistaken. According to Cuneo (The normative web: an argument for moral realism, Oxford University Press, Oxford, 2007), Das (Philos Q 66:152–160, 2016; Australas J Philos 95(1):58–69, 2017), Rowland (J Ethics Soc Philos 7(1):1–24, 2012; Philos Q 66:161–171, 2016) and others, epistemic facts would be just as (...) metaphysically problematic (or ‘guilty’) as moral facts. But since epistemic error theory is implausible, arguments for moral error theory prove too much and should be rejected. My aim is to argue that the success of this strategy is limited. In particular, the companions in guilt response fails against error-theoretic arguments motivated by concerns about explanatory dispensability, as recently developed by Joyce (The evolution of morality, MIT press, Bradford, 2005) and Olson (Moral error theory: history, critique, defence, Oxford University Press, Oxford, 2014: Ch. 7). To succeed, the response would require a prima facie plausible argument to the effect that epistemic facts are metaphysically dubious because they, too, are explanatorily dispensable. But, as I show, any such argument proves self-effacing: its premise commits us to believing in epistemic facts, while its conclusion forces us to deny their existence. Consequently, companions in guilt strategies don’t offer a panacea against arguments for moral error theory. (shrink)

Michael Devitt tells us that metaphysical realism has a kind of immunity from considerations concerning the nature of truth. Part of this immunity comes from Devitt’s insistence that realism is a metaphysical issue, not a semantic one. Most of Devitt’s critics have focused on this point, arguing that a proper understanding of the realism question necessarily involves semantic considerations :65–74, 1991; Miller in Synthese 136:191–217, 2003; Putnam in Comments on Michael Devitt’s ‘Hilary and Me’, in: Baghramian Reading Putnam. Taylor and (...) Francis, Hoboken, 2012; Taylor in Models, truth, and realism. Oxford University Press, New York, 2006). But Devitt also argues at length that semantic considerations should not lead us to give up on realism regardless of whether we admit that the correct characterization of realism is metaphysical in character or not. Devitt’s view hinges on the viability of a strategy which he calls Putting Metaphysics First, which essentially involves giving “a certain temporal and explanatory priority to metaphysical concerns”. Fully explicated, Devitt’s strategy is seen to be based on an epistemological naturalism in the vein of Quine. The main idea is that if we assume a naturalism according to which the only way to know anything is empirically through experience, then we will be able to establish a version of metaphysical realism early on in our investigations. According to Devitt, the empirical evidence for this realism is much stronger than the empirical evidence for the numerous semantical and epistemological views which are put forward in favor of antirealism. So, Devitt argues, we should hold on to the realism that we establish first and build our other theories on top of it. After detailing Devitt’s approach, I offer two objections. The first problem for Devitt is that in the process of putting metaphysics first, he puts epistemological naturalism first. This fact is in tension with his claim that epistemology is a weak starting place and a poor basis of theoretical revision. The second problem is that while our experiences of objects give us evidence that those objects exist, our experiences do not tell us that the objects exist mind-independently in all the ways required for metaphysical realism, or so I contend. Thus, I argue, even if we do put naturalized metaphysics first as Devitt recommends, realism is not secured as a starting point. (shrink)

Another view has entered the metaethical debate—relaxed realism [Dworkin 1996; Parfit 2011; Scanlon 2014]. Relaxed realists claim that there are irreducible moral properties, but seek to avoid the...

Is there anything wrong with publishing philosophical work which one does not believe (publishing without belief, henceforth referred to as ‘PWB’)? I argue that there is not: the practice isn’t intrinsically wrong, nor is there a compelling consequentialist argument against it. Therefore, the philosophical community should neither proscribe nor sanction it. The paper proceeds as follows. First, I’ll clarify and motivate the problem, using both hypothetical examples and a recent real-world case. Next, I’ll look at arguments that there is something (...) wrong with PWB, and show that none is sound. Then, I’ll give some reasons for thinking a norm against PWB is detrimental to the profession. Do I believe these arguments? If I’m right, it shouldn’t matter. (shrink)

According to Hume’s principle, a sentence of the form ⌜The number of Fs = the number of Gs⌝ is true if and only if the Fs are bijectively correlatable to the Gs. Neo-Fregeans maintain that this principle provides an implicit definition of the notion of cardinal number that vindicates a platonist construal of such numerical equations. Based on a clarification of the explanatory status of Hume’s principle, I will provide an argument in favour of a nominalist construal of numerical equations. (...) The neo-Fregean objections to such a construal will be examined and rejected. And the implications of the nominalist construal for the use of numerals and for the understanding of ontological questions for the existence of numbers will be spelled out. (shrink)

Truth is a fundamental philosophical concept that, despite its common and everyday use, has resisted common-sense formulations. At this point, one may legitimately wonder if there even is a common-sense notion of truth or what it could look like. In response, I propose here a common-sense account of truth based on four “truisms” that set a baseline for how to go about building an account of truth. Drawing on both ordinary language philosophy and contemporary pragmatic approaches to truth, I defend (...) a pragmatic, common-sense theory of truth. The result is a theory that focuses the use and function of truth while also emphasizing its “subject-independence.”. (shrink)

Smith has argued that moral realism need not be threatened by apparent moral disagreement. One reason he gives is that moral debate has tended to elicit convergence in moral views. From here, he argues inductively that current disagreements will likely be resolved on the condition that each party is rational and fully informed. The best explanation for this phenomenon, Smith argues, is that there are mind-independent moral facts that humans are capable of knowing. In this paper, I seek to challenge (...) this argument—and more recent versions of it—by arguing that historical convergence in moral views may occur for various arational reasons. If such reasons possibly result in convergence—which Smith effectively concedes—then the moral realist would require an additional a posteriori argument to establish that convergence in moral views occurred for the right reasons. Hence, Smith-style arguments, as they stand, cannot be mobilised in support of moral realism. Rather, this investigation demonstrates the necessity of a genuine history of morality for any convergence claim in support of a meta-ethical view. (shrink)

The answers to the questions in the title depend on the kind of pluralism one is talking about. We will focus here on our own views. The purpose of this article is to trace out some possible connections between these kinds of pluralism. We show how each of them might bear on the other, depending on how certain open questions are resolved.

This paper scrutinizes the debate over logical pluralism. I hope to make this debate more tractable by addressing the question of motivating data: what would count as strong evidence in favor of logical pluralism? Any research program should be able to answer this question, but when faced with this task, many logical pluralists fall back on brute intuitions. This sets logical pluralism on a weak foundation and makes it seem as if nothing pressing is at stake in the debate. The (...) present paper aims to improve this situation by looking at a promising case study and drawing general lessons about the kind of evidence that would support logical pluralism. I argue that the best motivation for logical pluralism will ultimately be rooted in certain kinds of performative data. (shrink)

This article examines Hilary Putnam's work in the philosophy of mathematics and - more specifically - his arguments against mathematical realism or objectivism. These include a wide range of considerations, from Gödel's incompleteness-theorem and the limits of axiomatic set-theory as formalised in the Löwenheim-Skolem proof to Wittgenstein's sceptical thoughts about rule-following, Michael Dummett's anti-realist philosophy of mathematics, and certain problems – as Putnam sees them – with the conceptual foundations of Peano arithmetic. He also adopts a thought-experimental approach – a (...) variant of Descartes' dream scenario – in order to establish the in-principle possibility that we might be deceived by the apparent self-evidence of basic arithmetical truths or that it might be ‘rational’ to doubt them under some conceivable set of circumstances. Thus Putnam assumes that mathematical realism involves a self-contradictory ‘Platonist’ idea of our somehow having quasi-perceptual epistemic ‘contact’ with truths that in their very nature transcend the utmost reach of human cognitive grasp. On this account, quite simply, ‘nothing works’ in philosophy of mathematics since wecan either cling to that unworkable notion of objective truth or abandon mathematical realism in favour of a verificationist approach that restricts the range of admissible statements to those for which we happen to possess some means of proof or ascertainment. My essay puts the case, conversely, that these hyperbolic doubts are not forced upon us but result from a false understanding of mathematical realism – a curious mixture of idealist and empiricist themes – which effectively skews the debate toward a preordained sceptical conclusion. I then go on to mount a defence of mathematical realism with reference to recent work in this field and also to indicate some problems – as I seethem – with Putnam's thought-experimental approach as well ashis use of anti-realist arguments from Dummett, Kripke, Wittgenstein, and others.

There has recently been a revival of interest in what truth is. For a long time, deflationism ruled the roost, telling us that there’s not much of metaphysical.

The argument from faultless disagreement against moral realism is based on the alleged possibility of cognitively faultless moral disagreement, CFD. This possibility contradicts the pre-theoretic intuition that moral truth is knowable, in principle, the so-called epistemic constraint on moral truth, EC. In this paper, I discuss the realist’s two options to cope with this argument. First of all, I point out the realist’s strategies to explain the possibility of cognitively faultless error, which is implied by CFD. Then I discuss one (...) promising option to respond to the argument from faultless disagreement: accepting both CFD and EC but blocking the ensuing contradiction by invoking an equivocation as regards the notion of knowability. After pointing out the drawbacks of this solution I discuss the other promising option: rejecting CFD by drawing on an agnostic stance on the part of cognitively blameless thinkers as regards moral propositions they cannot agree on. Yet this option faces the problem that EC has to be denied. In concluding the paper, I outline the prospects of an attractive objectivist shape of moral antirealism, which is also affected by the argument from faultless disagreement. (shrink)

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.

I know that I could have been where you are right now and that you could have been where I am right now, but that neither of us could have been turnips or natural numbers. This knowledge of metaphysical modality stands in need of explanation. I will offer an account based on our knowledge of the natures, or essencess, of things. I will argue that essences need not be viewed as metaphysically bizarre entities; that we can conceptualise and refer to (...) essences; and that we can gain knowledge of them. We can know about which properties are, and which properties are not, essential to a given entity. This knowledge of essence offers a route to knowledge of the ways those entities must be or could be. (shrink)

ABSTRACTEcumenical Alethic Pluralism is a novel kind of alethic pluralism. It is ecumenical in that it widens the scope of alethic pluralism by allowing for a normatively deflated truth property alongside a variety of normatively robust truth properties. We establish EAP by showing how Wright’s Inflationary Arguments fail in the domain of taste, once a relativist treatment of the metaphysics and epistemology of that domain is endorsed. EAP is highly significant to current debates on the nature of truth insofar as (...) it involves a reconfiguration of the dialectic between deflationists and pluralists. (shrink)

Some philosophers have argued that truth is a norm of judgement and have provided a variety of formulations of this general thesis. In this paper, I shall side with these philosophers and assume that truth is a norm of judgement. What I am primarily interested in here are two core questions concerning the judgement-truth norm: (i) what are the normative relationships between truth and judgement? And (ii) do these relationships vary or are they constant? I argue for a pluralist picture—what (...) I call Normative Alethic Pluralism (NAP)—according to which (i) there is more than one correct judgement-truth norm and (ii) the normative relationships between truth and judgement vary in relation to the subject matter of the judgement. By means of a comparative analysis of disagreement in three areas of the evaluative domain—refined aesthetics, basic taste and morality—I show that there is an important variability in the normative significance of disagreement—I call this the variability conjecture. By presenting a variation of Lynch’s scope problem for alethic monism, I argue that a monistic approach to the normative function of truth is unable to vindicate the conjecture. I then argue that normative alethic pluralism provides us with a promising model to account for it. (shrink)

What is the function of modal judgment? Why do we make judgments of possibility and necessity? Or are such judgments, in fact, dispensable? This paper introduces and develops an answer to these questions based on Kant’s remarks in section 76 of the Critique of Judgment. Here, Kant appears to argue the following: that a capacity to make modal judgments using modal concepts is required for a capacity for objective representation, in light of our split cognitive architecture. This split cognitive architecture (...) leaves room for a mismatch between our concepts and intuitions and, Kant argues, that is why we need modal concepts and modal judgments. In this paper, I develop this account of the function of modal judgment and to explore the extent to which it may improve upon contemporary alternatives. I focus on one particularly important challenge for the account: to explain why a distinction between the actual and the possible, rather than merely a distinction between the actual and the non-actual, is required. In order to answer this question, I supplement the account with a particular way of thinking about objectivity. (shrink)

A novel solution to the knowability paradox is proposed based on Kant’s transcendental epistemology. The ‘paradox’ refers to a simple argument from the moderate claim that all truths are knowable to the extreme claim that all truths are known. It is significant because anti-realists have wanted to maintain knowability but reject omniscience. The core of the proposed solution is to concede realism about epistemic statements while maintaining anti-realism about non-epistemic statements. Transcendental epistemology supports such a view by providing for a (...) sharp distinction between how we come to understand and apply epistemic versus non-epistemic concepts, the former through our capacity for a special kind of reflective self-knowledge Kant calls ‘transcendental apperception’. The proposal is a version of restriction strategy: it solves the paradox by restricting the anti-realist’s knowability principle. Restriction strategies have been a common response to the paradox but previous versions face serious difficulties: either they result in a knowability principle too weak to do the work anti-realists want it to, or they succumb to modified forms of the paradox, or they are ad hoc. It is argued that restricting knowability to non-epistemic statements by conceding realism about epistemic statements avoids all versions of the paradox, leaves enough for the anti-realist attack on classical logic, and, with the help of transcendental epistemology, is principled in a way that remains compatible with a thoroughly anti-realist outlook.

Moore’s paradox, the infamous felt bizarreness of sincerely uttering something of the form “I believe grass is green, but it ain’t”—has attracted a lot of attention since its original discovery (Moore 1942). It is often taken to be a paradox of belief—in the sense that the locus of the inconsistency is the beliefs of someone who so sincerely utters. This claim has been labeled as the priority thesis: If you have an explanation of why a putative content could not be (...) coherently believed, you thereby have an explanation of why it cannot be coherently asserted. (Shoemaker 1995). The priority thesis, however, is insufficient to give a general explanation of Moore-paradoxical phenomena and, moreover, it’s false. I demonstrate this, then show how to give a commitment-theoretic account of Moore Paradoxicality, drawing on work by Bach and Harnish. The resulting account has the virtue of explaining not only cases of pragmatic incoherence involving assertions, but also cases of cognate incoherence arising for other speech acts, such as promising, guaranteeing, ordering, and the like.

Constructivist approaches in epistemology and ethics offer a promising account of normativity. But constructivism faces a powerful Schmagency Objection, raised by David Enoch. While Enoch’s objection has been widely discussed in the context of practical norms, no one has yet explored how the Schmagency Objection might undermine epistemic constructivism. In this paper, I rectify that gap. First, I develop the objection against a prominent form of epistemic constructivism, Belief Constitutivism. Belief Constitutivism is susceptible to a Schmagency Objection, I argue, because (...) it locates the source of normativity in the belief rather than the agent. In the final section, I propose a version of epistemic constructivism that locates epistemic normativity as constitutive of agency. I argue that this version has the resources to respond to the Schmagency Objection. (shrink)

In the present paper I present the metalinguistic solutions to the ‘lost disagreement’ problem proposed Sundell and Plunkett [2013] and Barker [2012]. I argue that metalinguistic negotiations about taste, even though successful in explaining the intuition of disagreement in a vast number of cases, are not an accurate solution to the disagreement problem in contextualism when it comes to the most paradigmatic case of “tasty”. I also argue against the account of faultless disagreement explained via vagueness of taste predicates [Barker, (...) 2012]. I believe that the notion of faultlessness employed in the discussion of vagueness [Wright, 1994] is a different notion than the one employed in the discussion of taste discourse [Kölbel, 2003].

There is a fundamental disagreement about which norm regulates assertion. Proponents of factive accounts argue that only true propositions are assertable, whereas proponents of non-factive accounts insist that at least some false propositions are. Puzzlingly, both views are supported by equally plausible (but apparently incompatible) linguistic data. This paper delineates an alternative solution: to understand truth as the aim of assertion, and pair this view with a non-factive rule. The resulting account is able to explain all the relevant linguistic data, (...) and finds independent support from general considerations about the differences between rules and aims. (shrink)

This paper explores the nature of the concept of truth. It does not offer an analysis or definition of truth, or an account of how it relates to other concepts. Instead, it explores what sort of concept truth is by considering what sorts of thoughts it enables us to think. My conclusion is that truth is a part of each and every propositional thought. The concept of truth is therefore best thought of as the ability to token propositional thoughts. I (...) explore what implications this view has for existing accounts of concepts, and argue that truth is a concept unlike any other. (shrink)

In this article I am interpreting Friedrich Nietzsche's piece of writing "How the "True World" finally became a fable - The History of an Error" in the context of 20th-century analytical philosophy of language. In particular, I am going to argue that the main theme in this text - the issue of abolishing "the true world" - can be interpreted as Hilary Putnam's model-theoretic arguments against external realism and Saul Kripke's Wittgensteinian arguments against truth-conditional meaning theories. Interpreting this Nietzsche's text (...) with the help of these arguments gives rise to two options determining Nietzsche's own position. The perspective of Putnam's argument seems to push Nietzsche to the quietist camp - the view that significant metaphysical debate between external realism and its opposite is impossible or inexpressible. On the other hand, the Kripkensteinian perspective gives us reasons to interpret Nietzsche as an adherer of the pragmatic account of semantics, which explains meaning through the use of language.

_ Source: _Volume 7, Issue 4, pp 258 - 271 This contribution to the symposium on Annalisa Coliva’s _Extended Rationality_ is largely sympathetic with the moderate view of the structure of epistemic warrant which is defended in the book. However, it takes issue with some aspects of Coliva’s Wittgenstein-inspired ‘hinge epistemology’, focussing especially on her conception of propositional warrant, her treatment of epistemic closure, her antirealist conception of truth, and the significance of her answer to so-called Humean scepticism.

I offer a new theory of faultless disagreement, according to which truth is absolute (non-relative) but can still be non-objective. What's relative is truth-aptness: a sentence like ‘Vegemite is tasty’ (V) can be truth-accessible and bivalent in one context but not in another. Within a context in which V fails to be bivalent, we can affirm that there is no issue of truth or falsity about V, still disputants, affirming and denying V, were not at fault, since, in their context (...) of assertion V was bivalent. This theory requires a theory of assertion that is a form of cognitive expressivism. (shrink)

Even though pragmatic theories of truth are not widely held, they have advantages not found elsewhere. Here I focus on one such advantage: that a pragmatic theory of truth does not limit the range of truth-apt beliefs and thereby “block the way of inquiry.” Furthermore, I argue that this speaks for a particular formulation of the pragmatic theory of truth, one that shifts away from Peircean approaches and their emphasis on temporal independence, and toward a theory that instead emphasizes truth’s (...) subject independence.

This thesis comprises three main chapters—each comprising one relatively standalone paper. The unifying theme is fragmentalism about truth, which is the view that the predicate “true” either expresses distinct concepts or expresses distinct properties. -/- In Chapter 1, I provide a formal development of alethic pluralism. Pluralism is the view that there are distinct truth properties associated with distinct domains of subject matter, where a truth property satisfies certain truth-characterizing principles. On behalf of pluralists, I propose an account of logic (...) and semantics that shows how they can answer central conceptual and logical challenges for their view. -/- In Chapter 2, I motivate and develop a modal account of propositions on the basis of an iterative conception of propositions, where the modality is logico-mathematical. The modal account of propositions takes the conception to motivate an inherently potential hierarchy of propositions. I show that the account helps provide satisfying solutions to the intensional paradoxes of Russell-Myhill, Kaplan, and Prior. -/- In Chapter 3, I propose that “true” is polysemous. I suggest that “true” is initially polysemous between correspondence truth and disquotational truth, and further polysemous between the meanings corresponding to the subconcepts of the concept truth generated by the indefinite extensibility of that concept. I show that the proposal provides satisfying solutions to the semantic paradoxes. (shrink)

In this paper, we offer a brief, critical survey of contemporary work on truth. We begin by reflecting on the distinction between substantivist and deflationary truth theories. We then turn to three new kinds of truth theory—Kevin Scharp's replacement theory, John MacFarlane's relativism, and the alethic pluralism pioneered by Michael Lynch and Crispin Wright. We argue that despite their considerable differences, these theories exhibit a common "pluralizing tendency" with respect to truth. In the final section, we look at the underinvestigated (...) interface between metaphysical and formal truth theories, pointing to several promising questions that arise here. (shrink)

In To be is to be the object of a possible act of choice the authors defended Boolos’ thesis that plural quantification is part of logic. To this purpose, plural quantification was explained in terms of plural reference, and a semantics of plural acts of choice, performed by an ideal team of agents, was introduced. In this paper, following that approach, we develop a theory of concepts that—in a sense to be explained—can be labeled as a theory of logical concepts. (...) Within this theory, we propose a new logicist approach to natural numbers. Then, we compare our logicism with Frege’s traditional logicism. (shrink)

In this paper I consider the prospects for pluralism about knowledge, that is, the view that there is a plurality of knowledge relations. After a brief overview of some views that entail a sort of pluralism about knowledge, I focus on a particular kind of knowledge pluralism I call standards pluralism. Put roughly, standards pluralism is the view that one never knows anything simpliciter. Rather, one knows by this-or-that epistemic standard. Because there is a plurality of epistemic standards, there is (...) a plurality of knowledge relations. In §1 I argue that one can construct an impressive case for standards pluralism. In §2 I clarify the relationship between standards pluralism, epistemic contextualism and epistemic relativism. In §3 I argue that standards pluralism faces a serious objection. The gist of the objection is that standards pluralism is incompatible with plausible claims about the normative role of knowledge. In §4 I finish by sketching the form that a standards pluralist response to this objection might take. (shrink)

Inflationists have argued that truth is a causal-explanatory property on the grounds that true belief facilitates practical success: we must postulate truth to explain the practical success of certain actions performed by rational agents. Deflationists, however, have a seductive response. Rather than deny that true belief facilitates practical success, the deflationist maintains that the sole role for truth here is as a device for generalisation. In particular, each individual instance of practical success can be explained only by reference to a (...) relevant instance of a T-schema; the role of truth is just to generalise over these individualised explanations. I present a critical problem for this strategy. Analogues of the deflationist’s individualised explanations can be produced by way of explanation of coincidental instances of practical success where the agent merely has the right false beliefs. By deflationary lights, there is no substantive explanatory difference between such coincidental and non-coincidental instances of practical success. But the non-/coincidental distinction just is an explanatory distinction. The deflationist’s individualised explanations of non-coincidental instances of practical success must therefore be inadequate. However, I argue that the deflationist’s prospects for establishing an explanatory contrast between these cases by supplementing her individualised explanations are, at best, bleak. The inflationist, by contrast, is entitled to the obvious further explanatory premise needed to make sense of the distinction. As such, pending some future deflationary rejoinder, the deflationary construal of the principle that true belief facilitates practical success must be rejected; and with it the deflationary conception of truth.

In Being Realistic About Reasons T. M. Scanlon argues that particular fact about reasons are explained by contingent non-normative facts together with pure normative principles. A question then arises about the modal status of these pure principles. Scanlon maintains that they are necessary in a sense, and suggests that they are ‘metaphysically’ necessary. I argue that the best view for Scanlon to take, given his other commitments, is that these pure normative principles are metaphysically contingent in some cases and necessary (...) only in a weaker sense.

Metaethics is often dominated by both realist views according to which moral claims are made true by either non-natural or natural properties and by non-cognitivist views according to which these claims express desire-like attitudes. It is sometimes suggested that constructivism is a fourth alternative, but it has remained opaque just how it differs from the other views. To solve this problem, this article first describes a clear constructivist theory based on Crispin Wright’s anti-realism. It then outlines an argumentative strategy that (...) can be used to argue against constructivist views about practical reasons. The rest of the article explains how the outlined constructivist metaethical framework, reasons, and contractualism in normative ethics can still be used to create a new viable metaethical constructivist position about right and wrong.

Different people reason differently, which means that sometimes they reach different conclusions from the same evidence. We maintain that this is not only natural, but rational. In this essay we explore the epistemology of that state of affairs. First we will canvass arguments for and against the claim that rational methods of reasoning must always reach the same conclusions from the same evidence. Then we will consider whether the acknowledgment that people have divergent rational reasoning methods should undermine one’s confidence (...) in one’s own reasoning. Finally we will explore how agents who employ distinct yet equally rational methods of reasoning should respond to interactions with the products of each others’ reasoning. We find that the epistemology of multiple reasoning methods has been misunderstood by a number of authors writing on epistemic permissiveness and peer disagreement. (shrink)

This essay clarifies quantifier variance and uses it to provide a theory of indefinite extensibility that I call the variance theory of indefinite extensibility. The indefinite extensibility response to the set-theoretic paradoxes sees each argument for paradox as a demonstration that we have come to a different and more expansive understanding of ‘all sets’. But indefinite extensibility is philosophically puzzling: extant accounts are either metasemantically suspect in requiring mysterious mechanisms of domain expansion, or metaphysically suspect in requiring nonstandard assumptions about (...) mathematical objects. Happily, the view of quantifier meanings that underwrites quantifier variance can be used to provide an account of indefinite extensibility that is both metasemantically and metaphysically satisfying. Section 1 introduces the puzzle of indefinite extensibility; section 2 develops and clarifies the metasemantics of quantifier variance; section 3 solves section 1's puzzle of indefinite extensibility by applying section 2's account of quantifier meanings; and section 4 compares the theory developed in section 3 to several other theories in the literature.

Arguing that our attachment to Aristotelian modes of discourse makes a revision of their conceptual foundations long overdue, the author proposes the consideration of unacknowledged factors that play a central role in argument itself. These are in particular the subjective imprint and the dynamics of argumentation. Their inclusion in a four-dimensional framework and the focus on thesis validity allow for a more realistic view of our discourse practice. Exhaustive analyses of fascinating historical and contemporary arguments are provided. These range from (...) Columbus’s advocacy of the Western Passage to India, over the trial of King Louis XVI during the French Revolution, to today’s highly charged controversies surrounding euthanasia and embryo research. Excavating foundational issues such as the purpose of argument itself and the contested role of argument as a generator of knowledge, the book culminates in a discussion of the relationship between rationality and reasonableness and criticizes the restrictions of ‘rational’ argument relying on fixed logical, economic or cultural criteria that in reality are mutable. Here, a true, open argument requires the infusion of Paul Lorenzen’s principle of ‘transsubjectivity’, which recognizes but transcends the partiality of the individual and which can be seen in the pragmatic and expanding consensus that humanity can control itself to safeguard the future of a fragile, damaged world.

In this paper I investigate the claim that truth is a relational property. What does this claim really mean? What is its import?—Is it a basic feature of the concept of truth; or a distinctive feature of the correspondence theory of truth; or even both? After introducing some general ideas about truth, I begin by highlighting an ambiguity in current uses of the term ‘relational property’ in the truth debate, and show that we need to distinguish two separate ideas: that (...) truth is a relational property, and that truth is an extrinsic property. I go on to examine what both of these ideas are in more detail, and consider what would need to hold for truth to be in either of these categories. I then discern where all the main competitors in the truth debate stand on these issues. In doing so we learn more about these views and what they entail, and build a general picture of what stances different theories of truth take on whether truth is extrinsic or relational. Moreover, in doing this we will be able to answer one of the questions with which we began: whether truth’s being extrinsic or relational is something that, if accepted, lends support to the correspondence theory of truth. We will see that this is not so, and discern some interesting variations between various theories of truth on the issues of whether truth is extrinsic or relational. Following this we will be in a better position to judge whether the notions of extrinsicality or relationality are basic features of the concept of truth. In the final part of the paper I argue that, even if we are not in a position to conclude that they are basic features, they are features that any prospective theory of truth needs to take seriously.

The last two decades have seen a surge of support for normative quietism: most notably, from Dworkin, Nagel, Parfit and Scanlon. Detractors like Enoch and McPherson object that quietism is incompatible with realism about normativity. The resulting debate has stagnated somewhat. In this paper I explore and defend a more promising way of developing that objection: I’ll argue that if normative quietism is true, we can create reasons out of thin air, so normative realists must reject normative quietism.

Alethic pluralism holds that there are many truth properties. The view has been challenged to make sense of the notion of logical validity, understood as necessary truth preservation, when inferences involving different areas of discourse are concerned. I argue that the solution proposed by Edwards to solve the analogous problem of mixed compounds can straightforwardly be adapted to give alethic pluralists also a viable account of validity.
