Meet Tega. Blue, fluffy, and AI-enabled, Tega is a relational robot: a robot designed to form relationships with humans. Created to aid in early childhood education, Tega talks with children, plays educational games with them, solves puzzles, and helps in creative activities like making up stories and drawing. Children are drawn to Tega, describing him as a friend, and attributing thoughts and feelings to him ("he's kind," "if you just left him here and nobody came to play with him, he (...) might be sad"). Scholars and members of the public alike have raised the alarm about relational robots, worrying that the relationships that people, and especially children, form with such robots are objectionably inauthentic. We, members of an interdisciplinary team that developed and studies Tega, make this inauthenticity worry precise and offer practical recommendations for addressing it. We distinguish two kinds of (in)authenticity -- inauthenticity as unreality, and inauthenticity as deception -- arguing that neither is just what others have thought it is. With our distinction in hand, we argue that the authenticity concern can be met only through co-design methods -- methods that give stakeholders of all kinds (e.g. parents, educators, and children themselves) a genuine say in how relational robots are built.

Chemokines (chemotactic cytokines) drive and direct leukocyte traffic. New evidence suggests that the unusual CCR6/CCL20 chemokine receptor/ligand axis provides key homing signals for recently identified cells of the adaptive immune system, recruiting both pro‐inflammatory and suppressive T cell subsets. Thus CCR6 and CCL20 have been recently implicated in various human pathologies, particularly in autoimmune disease. These studies have revealed that targeting CCR6/CCL20 can enhance or inhibit autoimmune disease depending on the cellular basis of pathogenesis and the cell subtype most affected (...) through different CCR6/CCL20 manipulations. Here, we discuss the significance of this chemokine receptor/ligand axis in immune and inflammatory functions, consider the potential for targeting CCR6/CCL20 in human autoimmunity and propose that the shared evolutionary origins of pro‐inflammatory and regulatory T cells may contribute to the reason why both immune activation and regulation might be controlled through the same chemokine pathway.

Many scientific models are representations. Building on Goodman and Elgin’s notion of representation-as we analyse what this claim involves by providing a general definition of what makes something a scientific model, and formulating a novel account of how they represent. We call the result the DEKI account of representation, which offers a complex kind of representation involving an interplay of, denotation, exemplification, keying up of properties, and imputation. Throughout we focus on material models, and we illustrate our claims with the (...) Phillips-Newlyn machine. In the conclusion we suggest that, mutatis mutandis, the DEKI account can be carried over to other kinds of models, notably fictional and mathematical models. (shrink)

Scientific models are important, if not the sole, units of science. This thesis addresses the following question: in virtue of what do scientific models represent their target systems? In Part i I motivate the question, and lay out some important desiderata that any successful answer must meet. This provides a novel conceptual framework in which to think about the question of scientific representation. I then argue against Callender and Cohen’s attempt to diffuse the question. In Part ii I investigate the (...) ideas that scientific models are ‘similar’, or structurally morphic, to their target systems. I argue that these approaches are misguided, and that at best these relationships concern the accuracy of a pre-existing representational relationship. I also pay particular attention to the sense in which target systems can be appropriately taken to exhibit a ‘structure’, and van Fraassen’s recent argument concerning the pragmatic equivalence between representing phenomena and data. My next target is the idea that models should not be seen as objects in their own right, but rather what look like descriptions of them are actually direct descriptions of target systems, albeit not ones that should be understood literally. I argue that these approaches fail to do justice to the practice of scientific modelling. Finally I turn to the idea that how models represent is grounded, in some sense, in their inferential capacity. I compare this approach to anti-representationalism in the philosophy of language and argue that analogous issues arise in the context of scientific representation. Part iii contains my positive proposal. I provide an account of scientific representation based on Goodman and Elgin’s notion of representation-as. The result is a highly conventional account which is the appropriate level of generality to capture all of its instances, whilst remaining informative about the notion. I illustrate it with reference to the Phillips-Newlyn machine, models of proteins, and the Lotka-Volterra model of predator-prey systems. These examples demonstrate how the account must be understood, and how it sheds light on our understanding of how models are used. I finally demonstrate how the account meets the desiderata laid out at the beginning of the thesis, and outline its implications for further questions from the philosophy of science; not limited to issues surrounding the applicability of mathematics, idealisation, and what it takes for a model to be ‘true’.

Was Plato a Pythagorean? Plato's students and earliest critics thought so, but scholars since the nineteenth century have been more skeptical. With this probing study, Phillip Sidney Horky argues that a specific type of Pythagorean philosophy, called "mathematical" Pythagoreanism, exercised a decisive influence on fundamental aspects of Plato's philosophy. The progenitor of mathematical Pythagoreanism was the infamous Pythagorean heretic and political revolutionary Hippasus of Metapontum, a student of Pythagoras who is credited with experiments in harmonics that led to innovations (...) in mathematics. The innovations of Hippasus and other mathematical Pythagoreans, including Empedocles of Agrigentum, Epicharmus of Syracuse, Philolaus of Croton, and Archytas of Tarentum, presented philosophers like Plato with novel ways to reconcile empirical knowledge with abstract mathematical theories. Plato and Pythagoreanism demonstrates how mathematical Pythagoreanism established many of the fundamental philosophical questions Plato dealt with in his central dialogues, including Cratylus, Phaedo, Republic, Timaeus, and Philebus. In the process, it also illuminates the historical significance of the mathematical Pythagoreans, a group whose influence on the development of philosophical and scientific methods has been obscured since late antiquity. The picture that results is one in which Plato inherits mathematical Pythagorean method only to transform it into a powerful philosophical argument about the essential relationships between the cosmos and the human being.

Concludes that while the argument is vulnerable to the objection (found in Nabokov) that treating our past and future non-existence symmetrically leaves open the possiblity of increasing our anxieties rather than eliminating them, it remains rational, on Epicurean grounds, not do to so.

Sloan Situating Kant's philosophical project in relation to the natural sciences of his day has been of concern to several scholars from both the history of science and the (...) history of philosophy. Historians of philosophy have displayed an expanded awareness of, and interest in, the importance of the scientific context of the period in which Kant carried out his "Copernican" revolution. Most commonly among philosophers, this interest has been analyzed in relation to Kant's concerns with the foundations of mechanics, matter theory, and the epistemology of Newtonian science, with the central text of interest being the Metaphysische Anfangsgründe. On the other hand, historians of philosophy and historians of science, interested in the issues of the third Critique and in the several papers of Kant dealing with biological and anthropological issues, have emphasized the unified nature of Kant's inquiries into the natural sciences, and the importance of his continued interest in the life and human sciences alongside his interests in the foundations of the physical sciences.

The mass movement of people across the globe constitutes a major feature of world politics today. -/- Whatever the cause of the movement - often war, famine, economic hardship, political repression or climate change - the governments of western capitalist states see this 'torrent of people in flight' as a serious threat to their stability and the scale of this migration indicates a need for a radical re-thinking of both political theory and practice, for the sake of political, social and (...) economic justice. -/- This book argues that there is at present a serious gap between the legal and social practices of immigration and naturalisation in liberal democratic states and any theoretical justification for such practices that can be made within the tradition of liberal political philosophy. How can liberal states develop institutions of democratic citizenship and at the same time justifiably exclude 'outsiders' from participating in those institutions? The book examines various responses to this contradiction within the liberal tradition, and finds none of them satisfactory - there are no consistently liberal justifications for immigration control and this has serious implications both for liberal practice and theory.

This volume contains eighteen papers, three with new postscripts, that were written over the past 35 years. Five of the papers have not been previously published. Together they provide a comprehensive account of modal reality—the realm of possible worlds—from a Humean perspective, with excursions into neighboring topics in metaphysics. Part 1 sketches an account of reality as a whole, both the mathematical and the modal, defending a form of plenitudinous realism: every consistent proposition is true of some portion of reality. (...) Part 2 presents and defends a realist theory of concrete possible worlds with an absolute ontological distinction between the actual and the merely possible. Part 3 presents and defends a Humean account of modal plenitude, formulating and endorsing principles of recombination, of plenitude of possible structures, and of plenitude of alien contents. Part 4 applies the Humean account to truthmaking, mereology, spacetime, and quantities. I argue that holding fast to Humean strictures leads to views that differ in radical ways from those put forth by contemporary metaphysicians. (shrink)

Business ethics is a topic receiving much attention in the literature. However, the term 'business ethics' is not adequately defined. Typical definitions refer to the rightness or wrongness of behavior, but not everyone agrees on what is morally right or wrong, good or bad, ethical or unethical. To complicate the problem, nearly all available definitions exist at highly abstract levels. This article focuses on contemporary definitions of business ethics by business writers and professionals and on possible areas of agreement among (...) the available definitions. Then a definition is synthesized that is broad enough to cover the field of management in a sense as full as most managers might conceive of it. (shrink)

Composition as identity, as I understand it, is a theory of the composite structure of reality. The theory’s underlying logic is irreducibly plural; its fundamental primitive is a generalized identity relation that takes either plural or singular arguments. Strong versions of the theory that incorporate a generalized version of the indiscernibility of identicals are incompatible with the framework of plural logic, and should be rejected. Weak versions of the theory that are based on the idea that composition is merely analogous (...) to identity are too weak to be interesting, lacking in metaphysical consequence. I defend a moderate version according to which composition is a kind of identity, and argue that the difference is metaphysically substantial, not merely terminological. I then consider whether the notion of generalized identity, though fundamental, can be elucidated in modal terms by reverse engineering Hume’s Dictum. Unfortunately, for realists about possible worlds, such as myself,... (shrink)

We claim that scientists working with deep learning (DL) models exhibit a form of pragmatic understanding that is not reducible to or dependent on explanation. This pragmatic understanding comprises a set of learned methodological principles that underlie DL model design-choices and secure their reliability. We illustrate this action-oriented pragmatic understanding with a case study of AlphaFold2, highlighting the interplay between background knowledge of a problem and methodological choices involving techniques for constraining how a model learns from data. Building successful models (...) requires pragmatic understanding to apply modelling strategies that encourage the model to learn data patterns that will facilitate reliable generalisation. (shrink)

In this paper we explore the constraints that our preferred account of scientific representation places on the ontology of scientific models. Pace the Direct Representation view associated with Arnon Levy and Adam Toon we argue that scientific models should be thought of as imagined systems, and clarify the relationship between imagination and representation.

This paper investigates the identity and function of τὰ μεταξύ in Aristotle and the Early Academy by focussing primarily on Aristotle’s criticisms of Xenocrates of Chalcedon, the third scholarch of Plato’s Academy and Aristotle’s direct competitor. It argues that a number of passages in Aristotle’s Metaphysics (at Β 2, Μ 1-2, and Κ 12) are chiefly directed at Xenocrates as a proponent of theories of mathematical intermediates, despite the fact that Aristotle does not mention Xenocrates there. Aristotle complains that the (...) advocates for mathematical intermediates produce theories that are ontologically and epistemologically inefficient (related to, but not confined by, the “Uniqueness Problem”); that their so-called “intermediates” feature properties opposed to those of the forms on which those intermediates are thought to depend; and that what is μεταξύ must be between objects of a different genus. In all three cases, Aristotle’s criticisms are shown to be reactions to the metaphysics and cosmology of Xenocrates, especially his doctrine of the intermediary demonic isosceles triangle souls. Xenocrates emerges as a prime candidate for Aristotle’s critique of Platonist τὰ μεταξύ theories – equal to, and possibly even exceeding, Plato as target. (shrink)

It follows from Humean principles of plenitude, I argue, that island universes are possible: physical reality might have 'absolutely isolated' parts. This makes trouble for Lewis's modal realism; but the realist has a way out. First, accept absolute actuality, which is defensible, I argue, on independent grounds. Second, revise the standard analysis of modality: modal operators are 'plural', not 'individual', quantifiers over possible worlds. This solves the problem of island universes and confers three additional benefits: an 'unqualified' principle of compossibility (...) can be accepted; the possibility of nothing can be accommodated; and the identity of indiscernible worlds can be decisively refuted.

People may have open minds on whether a life-extending drug or technology is going to be developed before their sixties and may strongly desire that development. Do they therefore hope that it occurs? Do they hope for it in the substantive sense of “pinning their hopes” on the development? No, they do not. Hoping for a prospect in that sense certainly presupposes having an open mind on whether it will occur and having a desire for its occurrence. But, more crucially, (...) it means investing the prospect with a characteristic, galvanizing, and orientating role: it involves setting aside doubts about the possible nonoccurrence of the prospect and acting accordingly. This article offers a characterization of hope in that substantive sense and argues both that it can be rational and that it is ubiquitous. (shrink)

Moderate composition as identity holds that there is a generalized identity relation, “being the same portion of reality,” of which composition and numerical identity are distinct species. Composition is a genuine kind of identity; but unlike numerical identity, it fails to satisfy Leibniz’s Law. A composite whole and its parts differ with respect to their numerical properties: the whole is one; the parts (collectively) are many. Moderate composition as identity faces the challenge: how, in the absence of Leibniz’s Law, can (...) one characterize what counts as a genuine kind of identity? This paper explores a promising answer: a genuine kind of identity must satisfy a version of Leibniz’s Law restricted to properties that ascribe qualitative character. Strong composition as identity holds that there is only one identity relation, that it satisfies Leibniz’s Law, and that the parts are identical with the whole that they compose. Strong composition as identity faces the challenge of showing that numerical properties do not provide counterexamples to Leibniz’s Law, and doing so in a way that is compatible with the framework of plural logic that is needed to formulate the theory. The most promising way to do this is to hold that plural logic is fundamental at the level of our representations, but not fundamental at the level of being. At the level of being, portions of reality cannot be characterized as either singular or plural. It turns out that the proposed moderate theory and the proposed strong theory are one and the same. In spite of its many attractions, I reject it. The main issue has to do with whether slice-sensitive emergent properties are possible. I argue that they are, making use both of specific examples and general principles of modal plenitude. I do not claim that my arguments are irresistible. But they cannot be evaded as easily as a related argument against strong composition as identity given by Kris McDaniel. I critically examine McDaniel’s argument to pave the way for my own. (shrink)

According to David Lewis, a realist about possible worlds must hold that actuality is relative: the worlds are ontologically all on a par; the actual and the merely possible differ, not absolutely, but in how they relate to us. Call this 'Lewisian realism'. The alternative, 'Leibnizian realism', holds that actuality is an absolute property that marks a distinction in ontological status. Lewis presents two arguments against Leibnizian realism. First, he argues that the Leibnizian realist cannot account for the contingency of (...) actuality. Second, he argues that the Leibnizian realist cannot explain why skepticism about one's own actuality is absurd. In this paper, I mount a defense of Leibnizian realism. (shrink)

In this chapter, I survey what I call Lewisian approaches to modality: approaches that analyze modality in terms of concrete possible worlds and their parts. I take the following four theses to be characteristic of Lewisian approaches to modality. (1) There is no primitive modality. (2) There exists a plurality of concrete possible worlds. (3) Actuality is an indexical concept. (4) Modality de re is to be analyzed in terms of counterparts, not transworld identity. After an introductory section in which (...) I motivate analyzing modality in terms of possible worlds, I devote one section to each of these four theses. For each thesis, I take Lewis’s interpretation and defense as my starting point. I then consider and endorse alternative ways of accepting the thesis, some of which disagree substantially with Lewis’s interpretation or defense. There is more than one way to be a Lewisian about modality. (shrink)

This paper considers pick-the-winners contests as a simple method for harnessing the wisdom of crowds to produce probability forecasts. Pick-the-winners contests are those in which players pick the outcomes of selected future binary events with a prize going to the player with the most correct picks. In contrast to soliciting probability forecasts from experts, this paper shows that competition among players is to be encouraged because it improves the accuracy of the resulting crowd probability forecasts. This improvement comes because the (...) competition not only discourages the overbetting of favorites that occurs if prizes are awarded based on absolute performance, but also helps mitigate the public knowledge bias that occurs if everyone reports truthfully. In addition to the theoretical arguments, the paper analyzes picks from 6 years of pick-the-winners contests involving hundreds of players and 1037 college lacrosse games to find that the crowd proportions outperformed two benchmark sets of probabilities.

ABSTRACT Liberal political philosophy has little of interest to say about the social liberty of the physically disabled. It accepts that the physically disabled and the able‐bodied are equally at liberty, even though the former can do far less than the latter; and it concludes that there are no interesting political statements we can make about their situation. In this essay, I assume that the physically disabled are unfree, not merely unable, to use public facilities which do not take their (...) disability into account, thereby excluding them. I criticise liberal theories of liberty by exposing and questioning the assumptions which entail the liberal theorist's rejecting this claim. I conclude that there is a form of negative liberty which does enable the liberal theorist to make political statements about the freedom of the disabled [1]. (shrink)

In the course of a more than 70-year philosophical career and over 100 publications, Marjorie Grene (1910–2009) developed an original and coherent philosophical position that placed situated organic life at the center of the interpretation of reality and human affairs. Grene sometimes described this position as an “ecological epistemology” and summarized its central thrust in the expression “all knowledge is orientation.” However, Grene’s view incorporated a set of apparently or potentially opposed commitments such as naturalism and anti-reductionism, pluralism and realism, (...) and both a critique and affirmation of Darwinian evolutionary theory. This raises questions about precisely where Grene stood on the issues over which she argued and the coherence of her “ecological epistemology” as a whole. Here I review Grene’s work in the main research areas for which she is best known – history of philosophy, philosophy of biology, epistemology, and philosophical anthropology – with an eye to how these tensions were ultimately resolved in her account.

According to the Truthmaker Principle: every truth has a truthmaker. Spelled out a bit more exactly: for every true proposition, there is some entity whose existence entails, or necessitates, the truth of the proposition. A counterpart theorist can accept the Truthmaker Principle after all without buying into unmereological composition and mysterious necessary connections. This chapter introduces the idea of truthmaking, and considers how much truthmaking can be done by things without making controversial assumptions in modal metaphysics. It presents Armstrong's account (...) of truthmaking and the states of affairs needed to play the role of truthmakers. A fortiori should not be taken to be a version of the correspondence theory of truth. The chapter presents David Lewis's critique of the Truthmaker Principle, and the ontology of states of affairs that (typically) goes with it. Lewis's claim that he can accept the Truthmaker Principle is also presented here. (shrink)

The article explicates a notion of prudence according to which an agent acts prudently if he acts so as to satisfy not only his present preferences, but his past and future preferences as well.

The entry of time and history into biological systems of classification is perhaps the single most significant development in the history of biological systematics in the modern era.

In this chapter, I evaluate various conceptions of distance. Of the two most prominent, one takes distance relations to be intrinsic, the other extrinsic. I recommend pluralism: different conceptions can peacefully coexist as long as each holds sway over a distinct region of logical space. But when one asks which conception holds sway at the actual world, one conception stands out. It is the conception of distance embodied in differential geometry, what I call the Gaussian conception. On this conception, all (...) fundamental facts about distance are “local” facts.” But there is a problem: the Gaussian conception, notwithstanding its mathematical and physical credentials, appears metaphysically suspicious on Humean grounds. In the final section, I suggest that the Gaussian conception can be given a sound metaphysical footing in terms of non-standard analysis. (shrink)

I am a realist of a metaphysical stripe. I believe in an immense realm of "modal" and "abstract" entities, of entities that are neither part of, nor stand in any causal relation to, the actual, concrete world. For starters: I believe in possible worlds and individuals; in propositions, properties, and relations (both abundantly and sparsely conceived); in mathematical objects and structures; and in sets (or classes) of whatever I believe in. Call these sorts of entity, and the reality they comprise, (...) metaphysical. In contrast, call the actual, concrete entities, and the reality they comprise, physical. Physical and metaphysical reality together comprise all that there is. In this paper, it is not my aim to defend realism about any particular metaphysical sort of entity. Rather, I ask quite generally whether and how any brand of realism about metaphysical sorts of entity could be justified? (shrink)

If realism about possible worlds is to succeed in eliminating primitive modality, it must provide an 'analysis' of possible world: nonmodal criteria for demarcating one world from another. This David Lewis has done. Lewis holds, roughly, that worlds are maximal unified regions of logical space. So far, so good. But what Lewis means by 'unification' is too narrow, I think, in two different ways. First, for Lewis, all worlds are (almost) 'globally' unified: at any world, (almost) every part is directly (...) linked to (almost) every other part. I hold instead that some worlds are 'locally' unified: at some worlds, parts are directly linked only to "neighboring" parts. Second, for Lewis, each world is (analogically) 'spatio-temporally' unified; every world is 'spatio-temporally' isolated from every other. I hold instead: a world may be unified by nonspatio-temporal relations; every world is 'absolutely' isolated from every other. If I am right, Lewis's conception of logical space is impoverished: perfectly respectable worlds are missing. (shrink)

In this paper, I critique two conceptions of mechanisms, namely those put forth by Stuart Glennan (Erkenntnis 44:49–71, 1996; Philosophy of Science 69:S342–S353, 2002) and Machamer et al. (Philosophy of Science 67:1–25, 2000). Glennan’s conception, I argue, cannot account for mechanisms involving negative causation because of its interactionist posture. MDC’s view encounters the same problem due to its reificatory conception of activities—this conception, I argue, entails an onerous commitment to ontological dualism. In the place of Glennan and MDC, I propose (...) a “modified conception” of mechanisms, which (a) obviates the problem of negative causation by reinterpreting MDC’s activities according to a “descriptivist” account, and (b) avoids MDC’s problem by postulating a monistic ontology of entities. Thus, by solving these problems, my modified conception offers a cogent, more adequate alternative to Glennan’s and MDC’s conceptions of mechanisms. (shrink)

: The transplantation of adult human neural stem cells into prenatal non-humans offers an avenue for studying human neural cell development without direct use of human embryos. However, such experiments raise significant ethical concerns about mixing human and nonhuman materials in ways that could result in the development of human-nonhuman chimeras. This paper examines four arguments against such research, the moral taboo, species integrity, "unnaturalness," and human dignity arguments, and finds the last plausible. It argues that the transfer of human (...) brain or retinal stem cells to nonhuman embryos would not result in the development of human-nonhuman chimeras that denigrate human dignity, provided such stem cells are dissociated. The article provides guidelines that set ethical boundaries for conducting such research that are consonant with the requirements of human dignity. (shrink)

This paper seeks to show Kant’s importance for the formal distinction between descriptive natural history and a developmental history of nature that entered natural history discussions in the late eighteenth century. It is argued that he developed this distinction initially upon Buffon’s distinctions of ‘abstract’ and ‘physical’ truths, and applied these initially in his distinction of ‘varieties’ from ‘races’ in anthropology. In the 1770s, Kant appears to have given theoretical preference to the ‘history’ of nature [Naturgeschichte] over ‘description’ of nature (...) [Naturbeschreibung]. Following Kant’s confrontations with Johann Herder and Georg Forster in the late 1780s, Kant weakened the epistemic status of the ‘history of nature’ and gave theoretical preference to ‘description of nature’. As a result, Kant’s successors, such as Goethe, could draw from Kant either a justification for a developmental history of nature, or, as this paper argues, a warrant from the critical philosophy for denying the validity of the developmental history of nature as anything more than a ‘regulative’ idea of reason.

At the beginning of Republic 2 (358e–359b), Plato has Glaucon ascribe a social contract theory to Thrasymachus and ‘countless others’. This paper takes Glaucon’s description to refer both within the text to Thrasymachus’ views, and outside the text to a series of works, most of which have been lost, On Justice or On Law. It examines what is likely to be the earliest surviving work that presents a philosophical defence of law and justice against those who would prefer their opposites, (...) On Excellence by an anonymous author usually referred to as ‘Anonymus Iamblichi’; the views on these topics among the Socratics, including Crito, Simon the Cobbler, Aristippus of Cyrene, and Antisthenes; and Socrates’ debate with Hippias ‘On Justice’ in Xenophon’s Memorabilia (4.4.5–25). Its main contention is that the ‘countless others’ referred to by Glaucon points chiefly, but not solely, to the members of the circle of Socrates, who themselves espoused a range of views on justice and law, and their relations.

Since the publication of the successful animal trials of the Biobag, a prototypical extrauterine support for extremely premature neonates, numerous ethicists have debated the potential implications of such a device. Some have argued that the Biobag represents a natural evolution of traditional newborn intensive care, while others believe that the Biobag would create a new class of being for the patients housed within. Kingma and Finn argued inBioethicsfor making a categorical distinction between fetuses, newborns and ‘gestatelings’ in a Biobag on (...) the basis of a conceptual distinction between ectogenesis versus ectogestation. Applying their arguments to the clinical realities of newborn intensive care, however, demonstrates the inapplicability of their ideas to the practice of medicine. Here, I present three clinical examples of the difficulty and confusion their argument would create for clinicians and offer a possible remedy: namely, discarding the term ‘artificial womb’ in favour of ‘Biobag’.

Veritism, the position that truth is necessary for epistemic acceptability, seems to be in tension with the observation that much of our best science is not, strictly speaking, true when interpreted literally. This generates a paradox: truth is necessary for epistemic acceptability; the claims of science have to be taken literally; much of what science produces is not literally true and yet it is acceptable. We frame Elgin’s project in True Enough as being motivated by, and offering a particular resolution (...) to, this paradox. We discuss the paradox with a focus on scientific models and argue that there is another resolution available which is compatible with retaining veritism: rejecting the idea that scientific models should be interpreted literally.
