Once upon a time, logical conventionalism was the most popular philosophical theory of logic. It was heavily favored by empiricists, logical positivists, and naturalists. According to logical conventionalism, linguistic conventions explain logical truth, validity, and modality. And conventions themselves are merely syntactic rules of language use, including inference rules. Logical conventionalism promised to eliminate mystery from the philosophy of logic by showing that both the metaphysics and epistemology of logic fit into a scientific picture of reality. For (...) naturalists of all stripes, this was paradise. Alas, paradise was lost. By the end of the twentieth century, logical conventionalism had been almost universally abandoned. But more recently, it has been revitalized. This chapter provides an overview of logical conventionalism and its history, clears away misunderstandings, and briefly responds to both the canonical objections to conventionalism (from Quine, Dummett, Boghossian, and many others) as well as new objections (from Field and Golan). From paradise lost, to paradise regained: logical conventionalism is back. (shrink)

Distinctively mathematical explanations (DMEs) explain natural phenomena primarily by appeal to mathematical facts. One important question is whether there can be an ontic account of DME. An ontic account of DME would treat the explananda and explanantia of DMEs as ontic structures and the explanatory relation between them as an ontic relation (e.g., Pincock 2015, Povich 2021). Here I present a conventionalist account of DME, defend it against objections, and argue that it should be considered ontic. Notably, if indeed it (...) is ontic, the conventionalist account seems to avoid a convincing objection to other ontic accounts (Kuorikoski 2021). (shrink)

In what sense is the direction of time a matter of convention? In 'The Direction of Time', Hans Reichenbach makes brief reference to parallels between his views about the status of time’s direction and his conventionalism about geometry. In this article, I: (1) provide a conventionalist account of time direction motivated by a number of Reichenbach’s claims in the book; (2) show how forwards and backwards time can give equivalent descriptions of the world despite the former being the ‘natural’ (...) direction of time; and (3) argue that this offers an important middle-ground position between existing realist and antirealist accounts of the direction of time.

This paper defends a reading of Wittgenstein’s philosophy of mathematics in the Lectures on the Foundation of Mathematics as a radical conventionalist one, whereby our agreement about the particular case is constitutive of our mathematical practice and ‘the logical necessity of any statement is a direct expression of a convention’ (Dummett 1959, p. 329). -/- On this view, mathematical truths are conceptual truths and our practices determine directly for each mathematical proposition individually whether it is true or false. Mathematical truths (...) are thus not consequences of a prior adoption of a convention or rules as orthodox conventionalism has it. -/- The goal of the paper is not merely exegetical, however, and argues that radical conventionalism can withstand some of the most difficult objections that have been brought forward against it, including those of Dummett himself, and thus that radical conventionalism has been prematurely excluded from consideration by philosophers of mathematics.

ABSTRACT I motivate ‘Origin Conventionalism’—the view that which facts about one’s origins are essential to one’s existence depends partly on our person-directed attitudes. One important upshot is that the view offers a novel and attractive solution to the Nonidentity Problem. That problem typically assumes that the sperm-egg pair from which a person originates is essential to that person’s existence; in which case, for many future persons that come into existence under adverse conditions, had those conditions not been realized, the (...) individuals wouldn’t have existed. This is problematic because it delivers the counter-intuitive conclusion that it’s not wrong to bring about such adverse conditions since they don’t harm anyone. Origin Conventionalism, in contrast, holds that whether a person’s sperm-egg origin is essential to their existence depends on their person-directed attitudes. I argue that this provides a unique and attractive way of preserving the intuition that the actions in the ‘nonidentity cases’ are morally wrong because of the potential harm done to the individuals in question.

This article examines how Quine and Sellars develop informatively contrasting responses to a fundamental tension in Carnap’s semantics ca. 1950. Quine’s philosophy could well be styled ‘Essays in Radical Empiricism’; his assay of radical empiricism is invaluable for what it reveals about the inherent limits of empiricism. Careful examination shows that Quine’s criticism of Carnap’s semantics in ‘Two Dogmas of Empiricism’ fails, that at its core Quine’s semantics is for two key reasons incoherent and that his hallmark Thesis of Extensionalism (...) is untenable. The tension in Carnap’s semantics together with Quine’s exposure of the severe limits of radical empiricism illuminate central features of Sellars’s philosophy: the fully general form of the myth of givenness, together with Sellars’s alternative Kantian characterisation of understanding; the full significance of Carnap’s distinction between conceptual analysis and conceptual explication, and its important methodological implications; the specifically pragmatic character of Sellars’s realism; and Sellars’s methodological reasons for holding that philosophy must be systematic and that systematic philosophy must be deeply historically and textually informed. This paper thus re-examines this recent episode of philosophical history for its philosophical benefits and systematic insights. (shrink)

This paper examines popular‘conventionalist’explanations of why philosophers need not back up their claims about how‘we’use our words with empirical studies of actual usage. It argues that such explanations are incompatible with a number of currently popular and plausible assumptions about language's ‘social’character. Alternate explanations of the philosopher's purported entitlement to make a priori claims about‘our’usage are then suggested. While these alternate explanations would, unlike the conventionalist ones, be compatible with the more social picture of language, they are each shown to (...) face serious problems of their own.

A new reading of Plato's account of conventionalism about names in the Cratylus. It argues that Hermogenes' position, according to which a name is whatever anybody 'sets down' as one, does not have the counterintuitive consequences usually claimed. At the same time, Plato's treatment of conventionalism needs to be related to his treatment of formally similar positions in ethics and politics. Plato is committed to standards of objective natural correctness in all such areas, despite the problematic consequences which, (...) as he himself shows, arise in the case of language. (shrink)

A powerful objection against moral conventionalism says that it gives the wrong reasons for individual rights and duties. The reason why I must not break my promise to you, for example, should lie in the damage to you—rather than to the practice of promising or to all other participants in that practice. Common targets of this objection include the theories of Hobbes, Gauthier, Hooker, Binmore, and Rawls. I argue that the conventionalism of these theories is superficial; genuinely conventionalist (...) theories are not vulnerable to the objection; and genuine moral conventionalism is independently plausible.

This paper distinguishes three concepts of "race": bio-genomic cluster/race, biological race, and social race. We map out realism, antirealism, and conventionalism about each of these, in three important historical episodes: Frank Livingstone and Theodosius Dobzhansky in 1962, A.W.F. Edwards' 2003 response to Lewontin (1972), and contemporary discourse. Semantics is especially crucial to the first episode, while normativity is central to the second. Upon inspection, each episode also reveals a variety of commitments to the metaphysics of race. We conclude by (...) interrogating the relevance of these scientific discussions for political positions and a post-racial future. (shrink)

Against Thomas Mormann's argument that differential topology does not support Carnap's conventionalism in geometry we show their compatibility. However, Mormann's emphasis on the entanglement that characterizes topology and its associated metrics is not misplaced. It poses questions about limits of empirical inquiry. For Carnap, to pose a question is to give a statement with the task of deciding its truth. Mormann's point forces us to introduce more clarity to what it means to specify the task that decides between competing (...) hypotheses and in what way such a task may be both in practice and/or in principle impossible to carry out.

The role of conventions in the formulation of Thomas Reid’s theory of the geometry of vision, which he calls the “geometry of visibles”, is the subject of this investigation. In particular, we will examine the work of N. Daniels and R. Angell who have alleged that, respectively, Reid’s “geometry of visibles” and the geometry of the visual field are non-Euclidean. As will be demonstrated, however, the construction of any geometry of vision is subject to a choice of conventions regarding the (...) construction and assignment of its various properties, especially metric properties, and this fact undermines the claim for a unique non-Euclidean status for the geometry of vision. Finally, a suggestion is offered for trying to reconcile Reid’s direct realist theory of perception with his geometry of visibles. (shrink)

In this paper, I discuss the influential view that depiction, like language, depends on arbitrary conventions. I argue that this view, however it is elaborated, is false. Any adequate account of depiction must be consistent with the distinctive features of depiction. One such feature is depictive generativity. I argue that, to be consistent with depictive generativity, conventionalism must hold that depiction depends on conventions for the depiction of basic properties of a picture’s object. I then argue that two considerations (...) jointly preclude depiction from being governed by such conventions. Firstly, conventions must be salient to those who employ them. Secondly, those parts of pictures that depict basic properties of objects are not salient to the makers and interpreters of pictures. (shrink)

Geometry was a main source of inspiration for Carnap’s conventionalism. Taking Poincaré as his witness Carnap asserted in his dissertation Der Raum (Carnap 1922) that the metrical structure of space is conventional while the underlying topological structure describes "objective" facts. With only minor modifications he stuck to this account throughout his life. The aim of this paper is to disprove Carnap's contention by invoking some classical theorems of differential topology. By this means his metrical conventionalism turns out to (...) be indefensible for mathematical reasons. This implies that the relation between to-pology and geometry cannot be conceptualized as analogous to the relation between the meaning of a proposition and its expression in some language as logical empiricists used to say.

This article develops a constructive criticism of methodological conventionalism. Methodological conventionalism asserts that standards of inductive risk ought to be justified in virtue of their ability to facilitate coordination in a research community. On that view, industry bias occurs when conventional methodological standards are violated to foster industry preferences. The underlying account of scientific conventionality, however, is problematically incomplete. Conventions may be justified in virtue of their coordinative functions, but often qualify for posterior empirical criticism as research advances. (...) Accordingly, industry bias does not only threaten existing conventions but may impede their empirically warranted improvement if they align with industry preferences. My empiricist account of standards of inductive risk avoids such a problem by asserting that conventional justification can be pragmatically warranted but has, in principle, only a provisional status. Methodological conventions, therefore, should not only be defended from preference-based infringements on their coordinative function but ought to be subjected to empirical criticism. (shrink)

The Zhuangzi 莊子 depicts persons as surviving their deaths through the natural transformations of the world into very different forms—such as roosters, cart-wheels, rat livers, and so on. It is common to interpret these passages metaphorically. In this essay, however, I suggest employing a “Conventionalist” view of persons that says whether a person survives some event is not merely determined by the world, but is partly determined by our own attitudes. On this reading, Zhuangzi’s many teachings urging us to embrace (...) transformation are not merely a psychological aid for dealing with death, but also serve as a tool for literally surviving it.

The laws of classical logic are taken to be logical truths, which in turn are taken to hold objectively. However, we might question our faith in these truths: why are they true? One general approach, proposed by Putnam [8] and more recently Dickson [3] or Maddy [5], is to adopt empiricism about logic. On this view, logical truths are true because they are true of the world alone – this gives logical truths an air of objectivity. Putnam and Dickson both (...) take logical truths to be true in virtue of the world’s structure, given by our best empirical theory, quantum mechanics. This assumes a determinate logical structure of the world given by quantum mechanics. Here, I argue that this assumption is false, and that the world’s logical structure, and hence the related ‘true’ logic, is underdetermined. This leads to what I call empirical conventionalism.

Utilizing Einstein’s comparison of General Relativity and Descartes’ physics, this investigation explores the alleged conventionalism that pervades the ontology of substantival and relationist conceptions of spacetime. Although previously discussed, namely by Rynasiewicz and Hoefer, it will be argued that the close similarities between General Relativity and Cartesian physics have not been adequately treated in the literature—and that the disclosure of these similarities bolsters the case for a conventionalist interpretation of spacetime ontology.

I show that Locke anticipates key features of Hume’s more celebrated analysis of convention. I do so by developing Lenz’s account of Lockean (linguistic) convention and its normativity as presented in Socializing Minds. Locke’s account of linguistic convention shares structural features also visible in Locke’s treatment of the convention money and property. I show that Locke’s ‘Humean’ account of convention responds to a lacuna in Pufendorf’s treatment of linguistic convention that Lenz argues is significant to Locke.

Conventionalists hold that the sorts of events that one survives—such as teletransportation, or a brain transplant—is at least partly determined by our attitudes. But if Conventionalism is true, whose attitudes directly determine whether one survives? Do the individual's attitudes do all the work as Private Conventionalists hold, or do the community's attitudes also factor in as Public Conventionalists hold? There has recently been a greater push towards Private Conventionalism, while explicit arguments for Public Conventionalism are difficult to (...) come by. In this paper, I attempt to rectify the situation by presenting my case for Public Conventionalism. (shrink)

Conventionalism’ about personal-identity is an umbrella term for a cluster of views. All these views accept the core idea that conventions, or what are often known as person-directed practices, are crucially involved in the identity of persons over time, and that had those conventions or practices been different, the individuation and persistence conditions of persons would have been different.The purpose of this paper is not to argue for conventionalism broadly understood, nor for any particular version of conventionalism. (...) That is a task I, and others have undertaken elsewhere. Rather, since there is frequent confusion about conventionalism, I will first be concerned to clarify what it is that conventionalists really say about the identity of persons over time. Since there are a number of different views that broadly fall under the banner of conventionalism, it will be part of the task of this paper to disentangle these views and determine what they have in common and where they disagree.

According to conventionalist or conativist views about personal-identity, utterances of personal-identity sentences express propositions that are, in part, made true by the conative attitudes of relevant persons-stages. In this paper I introduce assessor relative conativism: the view that a personal-identity proposition can be true when evaluated at one person-stage's context and false when evaluated at another person-stage's context, because person-stages have different patterns of conative attitudes. I present several reasons to embrace assessor relative conativism over its more familiar realizer relative (...) cousin. (shrink)

A persistent worry concerning conventionalist accounts of law is that such accounts are ill equipped to account for law’s special normativity. I offer a particular kind of conventionalist account that is based on the practice-dependent account of conventional norms I have offered elsewhere and consider whether it is vulnerable to the Normativity Objection. I argue that it isn’t. It can account for all the ways in which law can justly claim to be normative. While there are ways of being normative (...) that it cannot account for, it is an error to suppose that law is normative in any of those ways. (shrink)

Truth by convention, once thought to be the foundation of a uniquely promising approach to explaining our access to the truth in nonempirical domains, is nowadays widely considered an absurdity. Its fall from grace has been due largely to the influence of an argument that can be sketched as follows: our linguistic conventions have the power to make it the case that a sentence expresses a particular proposition, but they can’t by themselves generate truth; whether a given proposition is true—and (...) so whether the sentence that expresses it is true—is a matter of what the world is like, which means it isn’t a matter of convention alone. The consensus is that this argument is decisive against truth by convention. Strikingly, though, it has rarely been formulated with much precision. Here I provide a new rendering of the argument, one that reveals its structure and makes transparent just what assumptions it requires, and then I assess conventionalists’ prospects for resisting each of those assumptions. I conclude that the consensus is mistaken: contrary to what is almost universally thought, there remains a promising way forward for the conventionalist project. Along the way, I clarify conventionalists’ commitments by thinking about what truth by convention would need to be like in order for conventionalism to do the epistemological work it’s intended to do.

In this paper I present a problem for the conventionalist regarding temporal metrics, and I defend an objectivist position on the ground of its explanatory force. Roughly, the conventionalist has it that there is no fact of the matter with respect to the truth or falsity of judgments of the kind “event e1 lasted as long as event e2”, while the objectivist thinks that they are grounded in objective features of space-time. I argue that, by positing grounds for judgments of (...) relative temporal length, the objectivist gains an explanatory force that the conventionalist position lacks. (shrink)

This paper defends the idea that there must be some joints in reality, some correct way to classify or categorize it. This may seem obvious, but we will see that there are at least three conventionalist arguments against this idea, as well as philosophers who have found them convincing. The thrust of these arguments is that the manner in which we structure, divide or carve up the world is not grounded in any natural, genuine boundaries in the world. Ultimately they (...) are supposed to pose a serious threat to realism. The first argument that will be examined concerns the claim that there are no natural boundaries in reality, the second one focuses on the basis of our classificatory schemes, which the conventionalist claims to be merely psychological, and the third considers the significance of our particular features in carving up the world, such as physical size and perceptual capabilities. The aim of this paper is to demonstrate that none of these objections succeed in undermining the existence of genuine joints in reality. (shrink)

The Westermarck Effect posits that intimate association during childhood promotes human incest avoidance. In previous work, I articulated and defended a version of the Westermarck Effect by developing a phylogenetic argument that has purchase within primatology but that has had more limited appeal for cultural anthropologists due to their commitment to conventionalist or culture-first accounts of incest avoidance. Here I look to advance the discussion of incest and incest avoidance beyond culture-first accounts in two ways. First, I shall dig deeper (...) into the disciplinary grooves within cultural anthropology that make attractive the view that incest has a naturalness to it that is countered only or primarily by explicit social rules, such as taboos. Second, I further explore the emerging, post-conventionalist view of incest avoidance in a more positive vein by elaborating on the nature of the Westermarckian mechanism and how it relates to such explicit social rules and our innate biological endowments. One general aim here is to overcome the bifurcation between perspectives that are seen as biological and those seen as cultural, preempting or countering the claim that rejecting culture-first accounts entails a form of biological reductionism, a general aim I have pursued in related publications on bioessentialism about kinship.

[EDIT: This book will be published open access. Check back around April 2024 to access the entire book.] One central aim of science is to provide explanations of natural phenomena. What role(s) does mathematics play in achieving this aim? How does mathematics contribute to the explanatory power of science? Rules to Infinity defends the thesis, common though perhaps inchoate among many members of the Vienna Circle, that mathematics contributes to the explanatory power of science by expressing conceptual rules, rules which (...) allow the transformation of empirical descriptions. Mathematics should not be thought of as describing, in any substantive sense, an abstract realm of eternal mathematical objects, as traditional platonists have thought. In Rules to Infinity, this view, which I call mathematical normativism, is updated with contemporary philosophical tools, and it is argued that normativism is compatible with mainstream semantic theory. This allows the normativist to accept that there are mathematical truths, while resisting the platonistic idea that there exist abstract mathematical objects that explain such truths. Furthermore, Rules to Infinity defends a particular account of the distinction between scientific explanations that are in some sense distinctively mathematical – those that explain natural phenomena in some uniquely mathematical way – and those that are only standardly mathematical, and it lays out desiderata for any account of this distinction. Normativism is compared with other prominent views in the philosophy of mathematics such as neo-Fregeanism, fictionalism, conventionalism, and structuralism. Rules to Infinity serves as an entry point into debates at the forefront of philosophy of science and mathematics, and it defends novel positions in these debates. (shrink)

In this work we present the function and we determine the nature of conventions and hypotheses for the scientific foundations according with the conventionalist doctrine that arose in France during the turning of the XIX century to the XX. The doctrine was composed by Henri Poincaré, Pierre Duhem and Édouard Le Roy. Moreover, we analyze the relation that conventions and hypotheses can establish with metaphysical thesis through criteria used by scientists in order to determine the preference for certain theories. Thereunto, (...) we promote an immanent interpretation of published works between 1891 and 1905. As result, we reveal that the authors, though being classified as belonging to the same doctrine, don't have only common grounds, but also divergences. Poincaré and Le Roy agree that geometrical conventions are chosen in accordance with convenience criteria. However, they disagree about the value convenience aggregate to scientific knowledge. In regards to natural phenomena, the three authors agree that reality can't be described univocally by the same set of conventions and hypotheses. Yet, Poincaré and Duhem both believe that there are experimental, rational and axiological criteria that justify scientist's satisfaction with certain theories and we indicate how those criteria are related with metaphysics. We conclude that conventionalists, even if warily and implicitly, searched to approach metaphysics in order to justify scientific activity. (shrink)

This article discusses the relationship (or lack thereof) between authors’ intentions and the meaning of literary works.

Why do promises give rise to reasons? I consider a quadruple of possibilities which I think will not work, then sketch the explanation of the normativity of promising I find more plausible—that it is constitutive of the practice of promising that promise-breaking implies liability for blame and that we take liability for blame to be a bad thing. This effects a reduction of the normativity of promising to conventionalism about liability together with instrumental normativity and desire-based reasons. This is (...) important for a number of reasons, but the most important reason is that this style of account can be extended to account for nearly all normativity—one notable exception being instrumental normativity itself. Success in the case of promises suggests a general reduction of normativity to conventions and instrumental normativity. But success in the cases of promises is already quite interesting and does not depend essentially the general claim about normativity. (shrink)

Several recent commentators argue that Thomas Hobbes’s account of the nature of science is conventionalist. Engaging in scientific practice on a conventionalist account is more a matter of making sure one connects one term to another properly rather than checking one’s claims, e.g., by experiment. In this paper, I argue that the conventionalist interpretation of Hobbesian science accords neither with Hobbes’s theoretical account in De corpore and Leviathan nor with Hobbes’s scientific practice in De homine and elsewhere. Closely tied to (...) the conventionalist interpretation is the deductivist interpretation, on which it is claimed that Hobbes believed sciences such as optics are deduced from geometry. I argue that Hobbesian science places simplest conceptions as the foundation for geometry and the sciences in which we use geometry, which provides strong evidence against both the conventionalist and deductivist interpretations.

This article defends a version of the Westermarck Effect, integrating existing clinical, biological, and philosophical dimensions to incest avoidance. By focusing on care-based attachment in primates, my formulation of the effect suggests the power of a phylogenetic argument widely accepted by primatologists but not by cultural anthropologists.

Locke's claims about the "inadequacy" of substance-ideas can only be understood once it is recognized that the "sort" represented by such an idea is not wholly determined by the idea's descriptive content. The key to his compromise between classificatory conventionalism and essentialism is his injunction to "perfect" the abstract ideas that serve as "nominal essences." This injunction promotes the pursuit of collections of perceptible qualities that approach ever closer to singling out things that possess some shared explanatory-level constitution. It (...) is in view of this norm regulating natural-historical inquiry that a substance-idea represents a sort for which some such constitution serves as the "real essence," i.e. as that on which all the sort's characteristic "properties" depend.

Standard truthmaker theory has generally assumed a realist account of de re modality and essences. But there are reasons to be skeptical about such a view, and for considering antirealist alternatives. Can truthmaker theory survive in the face of such skepticism? I argue that it can, but that only certain antirealist perspectives on de re modality are acceptable for truthmaker theory. In particular, either a quasi-realist or conventionalist account of de re modality is needed to provide the best account of (...) essential and accidental features that can be put to work in truthmaker theory. An important consequence of this approach is that it offers an account of truthmaking that is consistent with a nominalist perspective on properties, and yet fully respects the ontological ambitions driving truthmaker theory.

This paper offers an expressivist account of logical form, arguing that in order to fully understand it one must examine what valid arguments make us do (or: what Achilles does and the Tortoise doesn’t, in Carroll’s famed fable). It introduces Charles Peirce’s distinction between symbols, indices and icons as three different kinds of signification whereby the sign picks out its object by learned convention, by unmediated indication, and by resemblance respectively. It is then argued that logical form is represented by (...) the third, iconic, kind of sign. It is noted that icons uniquely enjoy partial identity between sign and object, and argued that this holds the key to Carroll’s puzzle. Finally, from this examination of sign-types metaphysical morals are drawn: that the traditional foes metaphysical realism and conventionalism constitute a false dichotomy, and that reality contains intriguingly inference-binding structures.

This dissertation investigates the concept of law in Rousseau, analyzing if he defends the idea of natural law or if he is a conventionalist. Some commentators, like Robert Derathé, conceive Rousseau as a naturalist, as opposed to others, like Charles Vaughan, who think that he is a conventionalist. Here we will critically assess those positions and try to see if they exclude each other or if Rousseau can be read, somehow, as defending fundamental aspects of those two positions.

ABSTRACT. In this paper, I defend a strong version of actual intentionalism. First, I argue against meaning subjectivism, conventionalism and contextualism. Second, I discuss what I take to be the most important rival to actual intentionalism, namely hypothetical intentionalism. I argue that, although hypothetical intentionalism might be acceptable as a definition of the concept of utterance meaning, it does not provide an acceptable answer to the question of what determines an utterance’s meaning. Third, I deal with the most serious (...) objection against actual intentionalism, namely the failure objection. I argue that the failure objection can be overcome within a framework of full-blown actual intentionalism if one distinguishes between categorial and semantic intentions. Moreover, I show how this version of actual intentionalism accounts for the possibility of innovative metaphors and other implicatures. Finally, I demonstrate that actual intentionalism – thus construed – makes it possible to distinguish between communicative failures and the intentional breaking of conventions. (shrink)

In this paper, we present a dialectical argument for a priori skepticism (i.e. the thesis that we can be skeptical about a priori knowledge). Then, we propose a framework that combines elements from inferential contextualism and logical conventionalism to offer a weak transcendental argument against a priori skepticism.

This essay explores Kaila's interpretation of the special theory of relativity. Although the relevance of his work to logical empiricism is well-known, not much has been written on what Kaila calls the ‘Einstein-Minkowski invariance theory’. Kaila's interpretation focuses on two salient features. First, he emphasizes the importance of the invariance of the spacetime interval. The general point about spacetime invariance has been known at least since Minkowski, yet Kaila applies his overall tripartite theory of invariances to space, time and spacetime (...) in an original way. Second, Kaila provides a non-conventionalist argument for the isotropic speed of electromagnetic signals. The standard Einstein synchrony is not a mere convention but a part of a larger empirical theory. According to Kaila's holistic principle of testability, which stands in contrast to the theses of translatability and verification, different items in the theory cannot be sharply divided into conventional and empirical. Kaila's invariantism/non-conventionalism about relativity reflects an interesting case in the gradual transition from positivism to realism within the philosophy of science. (shrink)

The purpose of this introduction is two-fold. First, it is to provide readers unfamiliar with the debates on practice-dependence with the insight necessary to fully comprehend the different contributions to this volume. Second, it is to make readers already well versed in practice-dependence more sensible to the substantive nature of this view and to provide them with a workable typology. After establishing a first distinction between metaphysical, relational and practice-dependent conceptions of justice, I draw a line, among practice-dependent views, between (...) institutionalism and cultural conventionalism. I complete the typology by differentiating between three forms of institutionalism according to how they regard the institutional fact, namely the fact that individuals are always already placed in a state of submission to existing institutions. Whereas de facto institutionalism describes this fact as a mere factual reality which imposes itself upon human beings, de jure institutionalism regards it as a practical necessity that stands in need of justification to each and every individual. Finally, moral institutionalism accounts for the institutional fact in terms of moral duty , namely the duty to contribute to the emergence of a state of affairs in which everyone’s freedom of choice is respected.

Can a set of musical metaphors in a treatise on ethics reveal something about the nature and source of moral autonomy? This article argues that it can. It shows how metaphorical usage of words like tone, pitch, and concord in Adam Smith's Theory of Moral Sentiments can be understood as elements of an analogical model for morality. What this model tells us about morality depends on how we conceptualise music. In contrast to earlier interpretations of Smith's metaphors that have seen (...) music as an aesthetic object, this article sees music as a practice. Understood in this way, the analogy allows us to see morality too as a practice––as moral tuning. This in turn reveals a novel answer to the intractable problem of conventionalism: moral autonomy consists in the freedom inherent in the constant need to interpret and reinterpret the strictly formal ideal of perfect propriety.

This project is an investigation into the prospects for an antirealist theory of essence. Essentialism is the claim that at least some things have some of their properties essentially. Essentialist discourse includes claims such as “Socrates is essentially human”, and “Socrates is accidentally bearded”. Historically, there are two ways of interpreting essentialist discourse. I call these positions ‘modal essentialism’ and ‘neo-Aristotelian essentialism’. According to modal essentialism, for Socrates to be essentially human is for it to be necessary that he be (...) a human if he exists, and for Socrates to accidentally have a beard is for it to be contingent that Socrates has a beard if he exists. According to neo-Aristotelian essentialism, objects have definitions in something like the way words do. For Socrates to be essentially human but accidentally bearded is for it to be part of the definition of Socrates that he is human, but not part of that definition that he is bearded. I argue that both are susceptible to antirealist interpretation. This thesis sets about showing that this is the case. In Chapters One and Two I investigate neo-conventionalist theories of modality, in the hope of using such a position to develop an antirealist modal essentialism. In Chapter Three I discuss the debate between modal and neo-Aristotelian essentialism and conclude that it is by no means settled. In Chapter Four I develop an antirealist neo-Aristotelian essentialism based on the mechanism of one of the neo-conventionalist accounts of modality. In Chapter Five I argue that this account is in a better position to give an essentialist theory of necessity than its realist counterparts. I conclude that, regardless of whether one is a modal or neo-Aristotelian essentialist, antirealist essentialism is a viable theory of essence that is worthy of consideration in contemporary debate.

How should we understand the Confucian doctrine of the rectification of names (zhengming): what does it mean that an object’s name must be in accordance with its reality, and why does it matter? The aim of this paper is to answer this question by advocating a novel interpretation of the later Confucian, Xunzi’s account of the doctrine. Xunzi claims that sage-kings ascribe names and values to objects by convention, and since they are sages, they know the truth. When we misuse (...) names, we are departing from a sagely convention of naming. As sagely convention determines moral truth, departure from the linguistic convention of the sages is a departure from moral truth. On my interpretation of Xunzi, the rectification of names is not a doctrine about what is true, but a doctrine about how we aim at truth. We are aiming at descriptive truth when our language conforms to the correct name of an object according to what I call ‘Confucian conventionalism’. When we correctly aim at descriptive truth we can aim at moral truth. Therefore, I claim that the doctrine of the rectification of names is concerned with discerning the literal accordance of language with an object (what is descriptively, linguistically true), to determine what is normatively, or morally, true. According to Xunzi, moral truth is grounded in linguistic truth. (shrink)

Are there any bona fide boundaries, i.e., boundaries that carve at the joints? Or is any boundary —hence any object—the result of a fiat articulation reflecting our cognitive biases and our so-cial practices and conventions? Does the choice between these two options amount to a choice between realism and wholesome relativism?
