Primitivists about truth maintain that truth cannot be analysed in more fundamental terms. Defences of primitivism date back to the early years of analytic philosophy, being offered by G.E. Moore, Bertrand Russell, and Gottlob Frege. In more recent years, a number of contemporary philosophers—including Donald Davidson, Ernest Sosa, Trenton Merricks, Douglas Patterson, and Jamin Asay—have followed suit, defending their own versions of primitivism. I'll begin by offering a brief history of primitivism, situating each of these views within the landscape of (...) primitivist truth theories and detailing some of their core motivations and apparent shortcomings. To close the discussion, I'll offer a diagnosis of the prospects of primitivism, focusing on the mystery challenge, which has loomed large throughout the history of primitivist truth theories, and the methodology that should be used in evaluating primitivist (and other) truth theories going forward.

Primitivist theories of truth have been defended by some of the luminaries of analytic philosophy, including the early Moore and Russell, Frege, Davidson, and Sosa. In this paper, I take up a contemporary primitivist theory that has been systematically developed throughout a sizeable body of work but has yet to receive sustained critical attention—Jamin Asay's primitivist deflationism. Asay's major ambitions are to defend a novel primitivist account of the concept truth and to harmonise that account with a deflationary theory of (...) the property truth. I will elaborate a thoroughgoing critique of primitivist deflationism, arguing that we have reason to doubt all of the five theses that constitute the view. Along the way, I will also highlight a number of possible escape routes for the primitivist deflationist, explaining how they can make the view more resilient even as they compel us to rework some of its central commitments.

Jamin Asay has recently argued that deflationists about the concept of truth cannot satisfactorily account for our alethic desires, i.e., those of our desires that pertain to the truth of our beliefs. In this brief reply, I show how deflationists can draw on well‐established psychological findings on framing effects to explain how the concept of truth behaves within the scope of our alethic desires.

In this paper, I propose a theory of living organisms that captures the insights of both traditional Aristotelian hylomorphism and John Dupré's “biological processualism”. Like traditional Aristotelian hylomorphism, the proposed theory understands material objects to be comprised of both matter and form. Unlike contemporary structural varieties of hylomorphism, however, it does not understand the form of a material object to be a relation, configuration, or structure exhibited by its parts but an activity or process in which its matter is continuously (...) engaged. Following Mark Steen, I call the proposed theory “Hyloenergeism”. As a version of hylomorphism, hyloenergeism better captures the inherent dynamism of living organisms than contemporary structural approaches. And it does so not by abandoning the substantialist paradigm, as Dupré's biological processualism does, but by reconceptualizing the nature of material substances as possessing a processual core. Hyloenergeism, then, paves a middle way for those looking for a substance view of living organisms sensitive to the concerns raised by contemporary processualist philosophers of biology. (shrink)

In this response, I reiterate my argument that price gouging undercuts the goal of equity in access to essential goods whereas Zwolinski emphasizes the importance of the efficient provision of essential goods above all other goals. I agree that the efficient provision of essential goods is important as I argue for the goal of equitable access to sufficient of the goods essential to living a minimally flourishing human life. However, efficiency is a means to this goal rather than the end (...) itself. Finally, I offer additional arguments against the non-worseness claim. (shrink)

In place of Tomasello's explanation for the source of moral obligation, we suggest that it develops from the concern for others already implicit in the human developmental system. Mutual affection and caring make the development of communication and thinking possible. Humans develop as persons within such relationships and this develops into respect and moral obligation.

This paper forms part of a wider campaign: to deny pointillisme. That is the doctrine that a physical theory's fundamental quantities are defined at points of space or of spacetime, and represent intrinsic properties of such points or point-sized objects located there; so that properties of spatial or spatiotemporal regions and their material contents are determined by the point-by-point facts. More specifically, this paper argues against pointillisme about the structure of space and-or spacetime itself, especially a paper by Bricker (1993). (...) A companion paper argues against pointillisme in mechanics, especially about velocity; it focusses on Tooley, Robinson and Lewis. To avoid technicalities, I conduct the argument almost entirely in the context of ``Newtonian'' ideas about space and time. But both the debate and my arguments carry over to relativistic, and even quantum, physics. (shrink)

Essentially everyone agrees that the outlawing of slavery, or the beginning of women’s suffrage, or the defeat of Nazism constitute paradigmatic examples of moral progress in human history. But this consensus belies a deep division about the nature of moral progress more generally, a consequence of the foundational differences among and within normative traditions regarding the nature and scope of the ‘moral’ in moral progress. This essay proposes that philosophers might nonetheless converge on a working definition of moral progress by (...) identifying a proxy property that reliably tracks moral progress, but which does not purport to be coextensive with the philosophically-relevant property. The aim of this essay is to identify this proxy property with emerging empirical measures of population welfare, and to show why this indicator of moral progress can garner overlapping consensus from a variety of normative traditions.

Karl Popper was one of the most influential philosophers of the twentieth century. His criticism of induction and his falsifiability criterion of demarcation between science and non-science were major contributions to the philosophy of science. Popper's broader philosophy of critical rationalism comprised a distinctive philosophy of social science and political theory. His critique of historicism and advocacy of the open society marked him out as a significant philosopher of freedom and reason. This book sets out the historical and intellectual contexts (...) in which Popper worked, and offers an overview and diverse criticisms of his central ideas. The volume brings together contributors with expertise on Popper's work, including people personally associated with Popper, specialists on the topics treated, and scholars with special interests in aspects of Popper's work.

In Section 2, I survey some of the ways that computers are used in mathematics. These raise questions that seem to have a generally epistemological character, although they do not fall squarely under a traditional philosophical purview. The goal of this article is to try to articulate some of these questions more clearly, and assess the philosophical methods that may be brought to bear. In Section 3, I note that most of the issues can be classified under two headings: some (...) deal with the ability of computers to deliver appropriate “evidence” for mathematical assertions, a notion that is explored in Section 4, while others deal with the ability of computers to deliver appropriate mathematical “understanding,” a notion that is considered in Section 5. Final thoughts are provided in Section 6. (shrink)

Pragmatic factors encroach on epistemic predicates not solely because the threshold for actionable belief may shift with an epistemic agent’s context, as an evidential Bayesian might insist, but also because what our inductive policy should be may shift with that context. I argue for this thesis in the context of imprecise probabilities, maintaining that the choice of the defining hyperparameter for an Imprecise Dirichlet Model for nonparametric predictive inference may correspond to the choice of an eager versus reticent inductive policy (...) in a way that can be sensitive to stakes and other practical circumstances.

Rationale One's understanding of medical progress – what it is, how it is pursued and how it is assessed – may be deeply dependent on one's understanding of the metaphysics of medicine, and of diseases in particular. -/- Aims and Objectives In this paper I present a new account of the nature of diseases, neither realist nor constructivist, and describe what progress in medicine looks like if we understand diseases in this way. -/- Conclusions This new account, Constructive Realism, may (...) provide a better account of medicine than either realism or constructivism.

The 1-consistency of arithmetic is shown to be equivalent to the existence of fixed points of a certain type of update procedure, which is implicit in the epsilon-substitution method.

This paper develops some ideas from previous work (coauthored, mostly with C.J.Isham). In that work, the main proposal is to assign as the value of a physical quantity in quantum theory (or classical physics), not a real number, but a certain kind of set (a sieve) of quantities that are functions of the given quantity. The motivation was in part physical---such a valuation illuminates the Kochen-Specker theorem; in part mathematical---the valuations arise naturally in the theory of presheaves; and in part (...) conceptual---the valuations arise from applying to propositions about the values of physical quantities some general axioms governing partial truth for any kind of proposition. In this paper, I give another conceptual motivation for the proposal. I develop (in Sections 2 and 3) the notion of a topos (of which presheaves give just one kind of example); and explain how this notion gives a satisfactory general framework for making sense of the idea of partial truth. Then I review (in Section 4) how our proposal applies this framework to the case of physical theories. (shrink)

Medical crowdfunding has raised many ethical concerns, among them that it may undermine privacy, widen health inequities, and commodify health care. One motivation for medical crowdfunding has received particular attention among ethicists. Recent studies have shown that many individuals are using crowdfunding to finance access to scientifically unsupported medical treatments. Recently, GoFundMe prohibited campaigns for antivaccination groups on the grounds that they “promote misinformation about vaccines” and for treatment at a German clinic offering unproven cancer treatments due to “the need (...) to make sure people are equipped to make well‐informed decisions.” GoFundMe has not taken any additional actions to regulate the much larger presence of campaigns seeking to fund unproven medical interventions on the platform. In this article, we make the ethical case for intervention by GoFundMe and other crowdfunding platforms. (shrink)

The prime number theorem, established by Hadamard and de la Vallée Poussin independently in 1896, asserts that the density of primes in the positive integers is asymptotic to 1/ln x. Whereas their proofs made serious use of the methods of complex analysis, elementary proofs were provided by Selberg and Erdos in 1948. We describe a formally verified version of Selberg's proof, obtained using the Isabelle proof assistant.

I present aspects of causal set theory (a research programme in quantum gravity) as being en route to achieving a reduction of Lorentzian geometry to causal sets. I take reduction in philosophers' sense; and I argue that the prospects are good for there being a reduction of the type envisaged by Nagel. (I also discuss the prospects for the stronger functionalist variant of Nagelian reduction, that was formulated by Lewis.) One main theme will be causal set theory's use of a (...) physical scale (viz. the Planck scale) to formulate how it recovers a Lorentzian manifold. This use illustrates various philosophical topics relevant to reduction, such as limiting relations between theories, and the role of analogy. I also emphasise causal set theory's probabilistic method, viz. Poisson sprinkling: which is used both for formulating the reduction and for exploring its prospects. (shrink)

In his book Mind and World, John McDowell grapples with the problem that the world must and yet seemingly cannot constrain our empirical thought. I first argue that McDowell’s proposed solution to the problem throws him onto the horns of his own, intractable dilemma, and thus fails to solve the problem of rational constraint by the world. Next, I will argue that Wilfrid Sellars, in a series of articles written in the 1950s and 1960s, provides the tools to solve the (...) dilemma McDowell sets before us. We will see how, borrowing from Sellars and certain neo-Sellarsians, we can solve the problem of rational constraint by perception without resorting to a McDowellian quasi-enchantment of the world.

I rst celebrate the immense success of twentieth century physics, but then urge that the future may bring many surprises, even in the basic structures of physical theories.

This book studies the diverse societies, cities, nations, economies, and regions of the Americas as they emerged in the Western hemisphere in the nineteenth and twentieth centuries. Drawing on the paradigms of social imaginaries and civilizational analysis, it explores regions of Central America, the Caribbean, the United States, and Latin America.

Jeffrey Stout's recent essay, "Public Reason and Dialectical Pragmatism", argues that theories of public reason in the tradition of Enlightenment rationalism, including its expression in the work of John Rawls, must be made over in an altogether more public fashion.1 That is, these theories must abandon the private machinations of philosophical minds and come to embrace the messy forums of public debate. There, as the rightful inheritance of democratic publics instead of the exclusive province of erudite philosophers, public reasoning—as a (...) progressive process—becomes an indispensable resource for the continual reconstruction of a liberal and deliberative democracy. Democracy, in Stout's view, is perpetually... (shrink)

This essay overcomes the division between “principled” and “strategic” approaches to nonviolence studies by demonstrating that ethical analysis is key to understanding movement strategy. I show how the moral phenomenologies of Martin Luther King Jr. and Emmanuel Lévinas, figures usually treated by scholars of principled nonviolence, possess genuine insight for nonviolent strategists. With reference to each thinker and supporting evidence from the #BlackLivesMatter movement, I argue that nonviolent resistance makes a moral appeal through the medium of the body to the (...) conscience of those bearing witness. Analysis of the way King combined moral reflection and strategic action recovers his legacy for the pragmatic tradition of social thought, while Lévinas's theory of the face offers additional considerations for nonviolent practitioners aiming for moral transformation at the local level. Studies that elucidate the complex moral dynamics by which nonviolent movements either succeed or fail will make the field a greater asset to practitioners. (shrink)

According to Jeffrey Brower’s hylomorphic account of material substances, prime matter and substantial forms together compose material substances, and material substances and accidental forms together compose accidental unities. In a recent article, Andrew Bailey has argued that Brower’s account has the counter-intuitive implication that no human person is ever the primary possessor, the primary thinker, of her own thoughts. In this paper, I consider various ways in which Brower might reply to this objection. I first consider several “invariant strategies”, solutions (...) that do not require any significant alteration to Brower’s account. I argue that these strategies are unsuccessful. I then introduce two ways of modifying Brower’s hylomorphic account of material substances so as to avoid Bailey’s objection. I argue that these “variant strategies” are successful, but they require that Brower significantly alter one or more of the main features of his account. (shrink)

By focusing on the caloric composition of hunted prey species, optimal foraging research has shown that hunters usually make economically rational prey choice decisions. However, research by meat scientists suggests that the gustatory appeal of wildlife meats may vary dramatically. In this study, behavioral research indicates that Mayangna and Miskito hunters in Nicaragua inconsistently pursue multiple prey types in the optimal diet set. We use cognitive methods, including unconstrained pile sorts and cultural consensus analysis, to investigate the hypothesis that these (...) partial preferences are influenced by considerations of meat flavor. Native informants exhibit high agreement on the relative appeal of different meats. Given the absence of other noteworthy differences between spider monkeys (Ateles geoffroyi) and howler monkeys (Alouatta palliata), the unappealing flavor of howler monkeys seems to be a factor in the partial preference for this species.

Because Sartre's theatre is one of representation and authenticity, plays like The Victors offer Sartrean philosophical explorations of subjects pushed to the limits of existence by torture and oppressive social edicts. It is in extreme situations that a subject most clearly exercises or fails to exercise his freedom and therefore his authenticity. But Sartre's interest in a complete explication of this process wanes before he fully outlines his project of self formation, which leaves the present paper to prove: (1) the (...) unattainability of any final or permanent authenticity, since each subject represents itself alternately in authentic and inauthentic ways and because the representations of a single subject are constantly in flux; (2) the primacy of representation as the force by which the self is formed and authenticity achieved or avoided; and (3) the criteria for the assessment of authenticity levels and how these processes come to light in plays like The Victors.

This book explores how thinking with Alfred North Whitehead and various continental philosophers can advance ideas about sustainability and civilization writ large. Contributors employ Whitehead and one or more continental thinkers around a given topic, whether philosophical or social, to produce the dislocations necessary for generating new ideas.
