Is the basic mechanism behind presupposition projection fundamentally asymmetric or symmetric? This is a basic question for the theory of presupposition, which also bears on broader issues concerning the source of asymmetries observed in natural language: are these simply rooted in superficial asymmetries of language use— language use unfolds in time, which we experience as fundamentally asymmetric— or can they be, at least in part, directly referenced in linguistic knowledge and representations? In this paper we aim to make progress on (...) these questions by exploring presupposition projection across conjunction, which has typically been taken as a central piece of evidence that presupposition projection is asymmetric. As a number of authors have recently pointed out, however, whether or not this conclusion is warranted is not clear once we take into account independent issues of redundancy. Building on previous work by Chemla & Schlenker (2012) and Schwarz (2015), we approach this question experimentally by using an inference task which controls for redundancy and presupposition suspension. We find strong evidence for left-to-right filtering across conjunctions, but no evidence for right-to-left filtering, suggesting that, at least as a default, presupposition projection across conjunction is indeed asymmetric.

Is the mechanism behind presupposition projection and filtering fundamentally asymmetric or symmetric? This is a foundational question for the theory of presupposition which has been at the centre of attention in recent literature :287–316, 2008b. https://doi.org/10.1515/THLI.2008.021, Semant Pragmat 2:1–78, 2009. https://doi.org/10.3765/sp.2.3; Rothschild in Semant Pragmat 4:1–43, 2011/2015. https://doi.org/10.3765/sp.4.3 a.o.). It also bears on broader issues concerning the source of asymmetries observed in natural language: are these simply rooted in superficial asymmetries of language use ; or are they, at least in (...) part, directly encoded in linguistic knowledge and representations? In this paper we aim to make progress on these questions by exploring presupposition projection across conjunction, which has traditionally been taken as a central piece of evidence that presupposition filtering is asymmetric in general. As a number of authors have recently pointed out, however, the evidence which has typically been used to support this conclusion is muddied by independent issues concerning redundancy; additional concerns have to do with the possibility of local accommodation. We report on a series of experiments, building on previous work by Chemla and Schlenker :177–226, 2012. https://doi.org/10.1007/s11050-012-9080-7) and Schwarz Experimental perspectives on presuppositions, Springer, Cham, 2015), using inference and acceptability tasks, which aim to control for both of these potential confounds. In our results, we find strong evidence for left-to-right filtering across conjunctions, but no evidence for right-to-left filtering—even when right-to-left filtering would, if available, rescue an otherwise unacceptable sentence. These results suggest that presupposition filtering across conjunction is asymmetric, contra suggestions in the recent literature :157–212, 2008a. https://doi.org/10.1515/THLI.2008.013, 2009 a.o.), and pave the way for the investigation of further questions about the nature of this asymmetry and presupposition projection more generally. Our results also have broader implications for the study of presupposition: we find important differences in the verdicts of acceptability versus inference tasks in testing for projected content, which has both methodological ramifications for the question of how to distinguish presupposed content, and theoretical repercussions for understanding the nature of projection and presuppositions more generally.

We characterize a type of functional explanation that addresses why a homologous trait originating deep in the evolutionary history of a group remains widespread and largely unchanged across the group’s lineages. We argue that biologists regularly provide this type of explanation when they attribute conserved functions to phenotypic and genetic traits. The concept of conserved function applies broadly to many biological domains, and we illustrate its importance using examples of molecular sequence alignments at the intersection of evolution and cell biology. (...) We use these examples to show how the study of conserved functions can integrate knowledge of a trait’s causal effects on fitness and its history of natural selection without invoking adaptation. We also show how conserved function provides a novel basis for addressing objections against evolutionary functions raised by Robert Cummins. (shrink)

The long-standing overarching policy governing research with human subjects conducted and supported by most federal agencies and departments in the United States, known as the Common Rule, has recently been revised, with most requirements slated to become effective in 2018. Although there are multiple alterations to the current regulations, some of the most significant changes aim to enhance consent for research. While some of the particular provisions in this regard will be easy to apply and promise to help meet this (...) goal, others may be more challenging to implement despite their intuitive appeal. In this article, I examine some of the provisions in the revised Common Rule that relate to consent: new required consent elements; the goal of comprehension in the consent process; consent forms; and broad consent. By raising issues about these provisions now and suggesting possible ways to overcome their potential shortfalls, the hope is that future efforts can be taken to help clarify and appropriately implement them.

It is now standard to interpret Aquinas as recognizing two main types of material objects: substances and artifacts, where substances are those material objects that result from some particular substantial form inhering in prime matter, and artifacts are those material objects that result from some particular accidental form inhering in one or more material substances. There are two problems with this standard interpretation. First, there are passages in which Aquinas states that accidental forms should be understood not as inhering in (...) substances from the outside, but as entering into their composition so as to be included among their metaphysical parts. Second, there are passages in which Aquinas states that it is impossible for any accidental form to be shared by two or more substances. This article considers what implications these two observations might have for how we understand the metaphysical structure of artifacts in Aquinas’s ontology. (shrink)

In this dissertation, I argue that we should be pluralists about truth and in turn, eliminativists about the property Truth. Traditional deflationists were right to suspect that there is no such property as Truth. Yet there is a plurality of pluralities of properties which enjoy defining features that Truth would have, were it to exist. So although, in this sense, truth is plural, Truth is non-existent. The resulting account of truth is indebted to deflationism as the provenance of the suspicion (...) that Truth doesn't exist. But it would be hasty to simply classify the account as deflationary. Each of the 'truth-like' properties that it recognizes is highly substantive--that is, complex and explanatorily potent. So we should deflate Truth by recognizing that it doesn't exist, but we should also recognize that one of the most vital tasks in truth theory is to discover the essences of the many truth-like properties. My aim here is to do precisely this. (shrink)

Anti-abortion violence (‘AAV’) is anathema to almost everyone, on all sides of the abortion debate. Yet, as this article aims to show, it is far more difficult than has previously been recognised to avoid the deeply unpalatable conclusion that it can sometimes be justified. Some of the most frequently-occupied positions on the morality of abortion will imply precisely that conclusion, I argue, unless conjoined with an especially stringent and unattractive form of pacifism. This is true not only of strict anti-abortion (...) views, but also, more surprisingly, of some of the most familiar and influential moderate defences of abortion rights. The latter conclusion raises the question, which further work will be required to fully resolve, of what our account of abortion ethics and prenatal moral status must be if it is to enable reconciliation of the common-sense rejections of both pacifism and AAV. I end with reasons to expect that the path to an account that satisfies this demand, without generating further significant intuitive problems, will be far from straightforward. (shrink)

The epsilon calculus is a logical formalism developed by David Hilbert in the service of his program in the foundations of mathematics. The epsilon operator is a term-forming operator which replaces quantifiers in ordinary predicate logic. Specifically, in the calculus, a term εx A denotes some x satisfying A(x), if there is one. In Hilbert's Program, the epsilon terms play the role of ideal elements; the aim of Hilbert's finitistic consistency proofs is to give a procedure which removes such terms (...) from a formal proof. The procedures by which this is to be carried out are based on Hilbert's epsilon substitution method. The epsilon calculus, however, has applications in other contexts as well. The first general application of the epsilon calculus was in Hilbert's epsilon theorems, which in turn provide the basis for the first correct proof of Herbrand's theorem. More recently, variants of the epsilon operator have been applied in linguistics and linguistic philosophy to deal with anaphoric pronouns. (shrink)

Deterministic physical theories are not beyond the reach of scientific discovery. From this fact I show that David Lewis was mistaken to think that small counterfactual perturbations from deterministic worlds involve violations of those world’s laws.

Hylomorphism is the theory according to which the entities within a specified domain are best understood as composed of both matter and form. Contemporary discussions of hylomorphism have found philosophers revisiting classic points of contention concerning the theory’s scope, application, and utility, but it has also led philosophers to carefully reconsider how best to understand hylomorphism’s most basic claims. In this introduction, I begin by providing a brief overview of some of these main points of discussion in the contemporary literature (...) on hylomorphism and some of the main hylomorphic views currently on offer. After that, I provide an overview of some of the main topics discussed in this special issue, offering a brief summary of each contribution. (shrink)

Acentral promise of human embryonic stem cell research is the potential to develop viable therapeutic approaches to a range of devastating diseases and conditions. Despite excitement over such advances, there are scientific and medical reasons to be cautious as stem cells and their products are introduced into patients. In response to such concerns, the International Society for Stem Cell Research as well as ad hoc groups and individuals have offered approaches to governance of this research. While there are similarities among (...) these governance models and they are in principle easily endorsable, in this paper I raise a set of concerns related to their implementation, suggesting areas where gathering data may facilitate more appropriate oversight. Next, I suggest areas that seem to have been neglected as these governance models have been developed so that they may be on the agendas of those seeking to revise these models in the future. Finally, I describe how some of the concerns that have arisen in considering the appropriate governance of stem cell research may be useful in science and translational research more broadly.

Despite concern that patients in the intensive care unit (ICU) may not be treated with respect and dignity, there is not conceptual clarity regarding what constitutes such treatment. In addition, measures specific to treatment with respect and dignity in the ICU are unavailable. Accordingly, a multidisciplinary group developed a conceptual model for treatment with respect and dignity in the ICU and used mixed methods to gather data on this issue. This effort included interviews with patients and families, focus groups with (...) health care professionals, and direct observations. These data were then compared and contrasted to synthesize what was learned. Finally, pilot quantitative patient and family survey data were collected and analyzed. Each of these approaches, which comprise the papers in this supplement to Narrative Inquiry in Bioethics, is briefly described in this article. (shrink)

We show that certain model-theoretic forcing arguments involving subsystems of second-order arithmetic can be formalized in the base theory, thereby converting them to effective proof-theoretic arguments. We use this method to sharpen the conservation theorems of Harrington and Brown-Simpson, giving an effective proof that WKL+0 is conservative over RCA0 with no significant increase in the lengths of proofs.

Stem cell-based innovation is one pathway to clinical translation that stands in contrast to clinical research and medical treatment. After reviewing recently issued guidelines for responsible innovation, this article examines the potential benefits and harms of using this pathway as well as practical barriers and conceptual concerns regarding it.

In earlier articles, the author developed what is known as the "Supersession Thesis," asserting that historic injustice may be overtaken by changes in circumstances so that a situation that was unjust when it was brought about may coincide with what justice requires at a later time. The Supersession Thesis was developed initially as a tool for considering historic injustice suffered by indigenous peoples in the European settlement of countries like Australia, Canada, New Zealand, and the United States. In this paper, (...) the author explores the application of the Supersession Thesis to issues about the Palestinian right of return and also to Israeli settlements in the Occupied Territories. The paper argues that, while it is not unthinkable that the Supersession Thesis might eventually legitimize the settlements and undermine the Palestinian right of return, there is no guarantee that this will happen. The application of the Supersession Thesis does not depend on the passage of time, but on changes in circumstances that a theory of justice makes relevant. Many of the circumstances that make the Supersession Thesis relevant to the post-colonial situations described do not apply in the Israeli situation. Nevertheless, it is worth considering the possibility of applying the Supersession Thesis in this case, because it enables us to assess the merits of the Thesis more sharply in relation to injustice that is taking place now, as opposed to injustice that took place in the nineteenth century.

Complementary and alternative medicine is used by many in hopes of achieving important health-related goals. Survey data indicate that 42 percent of the U.S. population uses CAM, accounting for 629 million “office” visits a year and expenditures of 27 billion dollars. This high prevalence of use calls for a careful evaluation of CAM so as to ensure the well-being of those using its modalities. Such an evaluation would obviously include assessments of the safety and efficacy of particular approaches, the training (...) and integrity of practitioners, and the appropriateness of modalities for different conditions or uses. Given the lack of published data concerning many of these aspects of CAM, the likely unfamiliarity of its practitioners to the approaches available to clinicians practicing modern scientific medcine, and the need to respect the unique preferences of persons seeking assistance with achieving health-related goals, it is also important to assess the potential roles of informed consent for the use of CAM. Examining such roles is the central task of this paper. (shrink)

ArgumentThis paper examines the field network – linking together lay observers in geographically distributed locations with a central figure who aggregated their locally produced observations into more general, regional knowledge – as a historically emergent mode of knowledge production. After discussing the significance of weather knowledge as a vital domain in which field networks have operated, it describes and analyzes how a more robust and systematized weather observing field network became established and maintained on the ground in the early twentieth (...) century. This case study, which examines two Kansas City-based local observer networks supervised by the same U.S. Weather Bureau office, demonstrates some of the key issues involved in maintaining field networks, such as the role of communications infrastructure, especially the telegraph, the procedures designed to make local observation more systematic and uniform, and the centralized, hierarchical power relations that underpinned even a low-status example of knowledge production on the periphery.

My aim in this article is programmatic. I argue that understanding perceptual experience on the model of perceptual affordances allows us to acknowledge the centrality of embodiment to moral phenomenology, on the one hand, and to see more transparently the place of the emotions in the moral life, on the other. I suggest some means by which moral perception, construed as the perception of moral affordances, might be cultivated.

In 1837, Dirichlet proved that there are infinitely many primes in any arithmetic progression in which the terms do not all share a common factor. We survey implicit and explicit uses ofDirichlet characters in presentations of Dirichlet’s proof in the nineteenth and early twentieth centuries, with an eye toward understanding some of the pragmatic pressures that shaped the evolution of modern mathematical method.

What is the scope of morality? To whom are we obligated? Whom are we morally required to help? Whom may we not harm? Whom commands our respect and from whom are we forbidden to withhold our assistance? Do moral concerns and requirements diminish over distance, so that our duties are stronger to those who are near to us, and weaken to vanishing point as possible beneficiaries of our actions and inactions are found further and further away? And what does “distance” (...) mean in these circumstances? When is a person near to me? When is a person far away? Is it a matter of who they are, and of their relation to me? Or is it sheer geography? If it is geography, does a person count as near or far in virtue of where they live or in virtue of where they happen to be? (shrink)

Sometimes Always True aims to resolve, through a re-understanding of the nature of sense, three connected problems central to philosophical thought: that genuine pluralism must make room for outlooks that exclude pluralism, that philosophy ultimately explores sense as a whole and so must in some way step outside of sense, and that our experience of the deep questions of life therefore similarly involves suspensions of sense itself.

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)

A number of classical theories are interpreted in analogous theories that are based on intuitionistic logic. The classical theories considered include subsystems of first- and second-order arithmetic, bounded arithmetic, and admissible set theory.

An alethic holding is any speech act that functions to hold another person to acting for reasons that they already had prior to the performance of a speech act with this function. Although it is tempting to think of such acts as either informing another person of extant reasons for acting or as creating new reasons for that person to so act, a central goal of this paper is to suggest that this temptation should be resisted. First, alethic speech acts (...) are situated within the broader terrain of performances that strive to hold others responsible. Second, the precise sense of ‘holding’ to reason that characterizes an alethic speech act is explicated, in a manner that distinguishes such acts from either those designed to inform one of extant norms or to add new norms. Third, an account that attempts to explain how a speech act can achieve this holding function is offered, one based on the idea of a self-conscious interpersonal, transaction. Finally, it is suggested that the terrain of holding other’s responsible sketched at the outset looks different once this account of alethic holdings is in view. (shrink)

Drawing on the paradigms of social imaginaries and civilizational analysis, it explores regions of Central America, the Caribbean, the United States, and Latin America.

Active monitoring of research with human subjects is no longer reserved for especially complex research or investigating research alleged to be problematic. Rather, many human research subjects’ protection programmes now engage in routine monitoring. Although limited data concerning such monitoring are available, the Association for the Accreditation of Human Research Protection Programs , reports that in 2011 its accredited organisations conducted many routine audits .1 While accredited organisations currently represent a small subset of human subjects’ research programmes, these data are (...) consistent with AAHRP's standard : ‘The Organization measures and improves, when necessary, compliance with organizational policies and procedures and applicable laws, regulations, codes, and guidance. The Organization also measures and improves, when necessary, the quality, effectiveness, and efficiency of the Human Research Protection Program.’2In this issue of Journal of Medical Ethics ….

The Patient Self-Determination Act (PSDA) requires hospitals to ask patients upon admission whether they have an advance directive. Although the PSDA has received extensive criticism, little attention has been paid to the cost of the law, either during its legislative course or following its implementation. Nonetheless, several tangible and intangible costs are associated with the PSDA. Such costs may be incurred by different parties. This paper examines the costs and benefits of the PSDA and illustrates the extent of some of (...) its tangible costs. The incremental start-up cost for one institution's response to the PSDA is estimated to be $49,304 ($1.31 per admission) and the total implementation cost of the program to be $114,528. In addition, the national incremental start-up cost for hospitals to implement the PSDA is estimated to be between $43,625,114 and $101,569,922. Finally, the potential implications of the PSDA for future governmental health care ethics regulation are discussed. (shrink)

In standard models of decision making, participation in violent political action is understood as the product of instrumentally rational reasoning. According to this line of thinking, instrumentally rational individuals will participate in violent political action only if there are selective incentives that are limited to participants. We argue in favor of an alternate model of political violence where participants are motivated by moral commitments to collective sacred values. Correlative and experimental empirical evidence in the context of the Israeli–Palestinian conflict strongly (...) supports this alternate view. (shrink)

In May 1973 a new collaboration between NASA, the Indian Health Service, and the Lockheed Missiles and Space Company promised to transform the way members of the Papago (now Tohono O’odham) Tribe of southern Arizona accessed modern medicine. Through a system of state-of-the-art microwave relays, slow-scan television links, and Mobile Health Units, the residents of the third-largest American Indian reservation began to access physicians remotely via telemedical encounters instead of traveling to distant hospitals. Examining the history of the STARPAHC (Space (...) Technology Applied to Rural Papago Advanced Health Care) project from the perspective of NASA and its contractors, from the perspective of the Indian Health Service, and from the perspective of O’odham engineers and health professionals offers a new focus, emphasizing the American Indian reservation as a site of medical research and technological development in the late twentieth century, with specific attention to the promise of information technology to address health disparities and the role of American Indians as actors in the late twentieth-century history of science, technology, and medicine.
