One argument for the thirder position on the Sleeping Beauty problem rests on direct inference from objective probabilities. In this paper, I consider a particularly clear version of this argument by John Pollock and his colleagues (The Oscar Seminar 2008). I argue that such a direct inference is defeated by the fact that Beauty has an equally good reason to conclude on the basis of direct inference that the probability of heads is 1/2. Hence, neither thirders nor halfers can find (...) direct support in an appeal to objective probabilities. (shrink)

The literature has shown that different types of moral dilemmas elicit discrepant decision patterns. The present research investigated the role of uncertainty in contributing to these decision patterns. Two studies were conducted to examine participants' choices in commonly used dilemmas. Study 1 showed that participants’ perceived outcome probabilities were significantly associated with their moral choices, and that these associations were independent from the dilemma type. Study 2 revealed that participants had significantly less preference for killing the individual when the outcome (...) probabilities were stated using the modal verb ‘will’ than when they were stated using the numerical phrasing of ‘100%’. Our findings illustrate a discord between experimenter and participant in the interpretation of task instructions. (shrink)

Vers la fin du XIVe siècle se fait jour une théorie du signe et de la signification qui, par une réélaboration des principaux concepts sémantiques, renouvelle toute l’analyse logique du langage.Partant de Guillaume d’Ockham, dont l’œuvre est ici décisive, cet ouvrage suit le développement d’une logique fondée sur des éléments de sémiologie, à travers différents auteurs du XIVe siècle tels que Gauthier Burley, Jean Buridan, Albert de Saxe, Marsile d’Inghen, Pierre d’Ailly...Une telle « logique du signe » prend place dans (...) toute une mutation du savoir, en ce siècle où la crise profonde du monde médiéval appelle une autre conception des rapports entre l’homme, les choses extérieures et le langage.

I argue for the view that some we-thoughts are immune to error through misidentification (IEM) relative to the first-person plural pronoun. To prepare the ground for this argument I defend an account of the semantics of ‘we’ and note the variety of different uses of that term. I go on to defend the IEM of a certain range of we-thoughts against a number of objections.

Biological evolution provides a creative fount of complex and subtle adaptations, often surprising the scientists who discover them. However, because evolution is an algorithmic process that transcends the substrate in which it occurs, evolution’s creativity is not limited to nature. Indeed, many researchers in the field of digital evolution have observed their evolving algorithms and organisms subverting their intentions, exposing unrecognized bugs in their code, producing unexpected adaptations, or exhibiting outcomes uncannily convergent with ones in nature. Such stories routinely reveal (...) creativity by evolution in these digital worlds, but they rarely fit into the standard scientific narrative. Instead they are often treated as mere obstacles to be overcome, rather than results that warrant study in their own right. The stories themselves are traded among researchers through oral tradition, but that mode of information transmission is inefficient and prone to error and outright loss. Moreover, the fact that these stories tend to be shared only among practitioners means that many natural scientists do not realize how interesting and lifelike digital organisms are and how natural their evolution can be. To our knowledge, no collection of such anecdotes has been published before. This paper is the crowd-sourced product of researchers in the fields of artificial life and evolutionary computation who have provided first-hand accounts of such cases. It thus serves as a written, fact-checked collection of scientifically important and even entertaining stories. In doing so we also present here substantial evidence that the existence and importance of evolutionary surprises extends beyond the natural world, and may indeed be a universal property of all complex evolving systems.

Biocentrism, a prominent view in environmental ethics, is the notion that all and only individual biological organisms have moral status, which is to say that their good ought to be considered for its own sake by moral agents. I argue that biocentrism suffers two serious problems: the Origin Problem and the Normativity Problem. Biocentrism seeks to avoid the absurdity that artifacts have moral status on the basis that organisms have naturalistic origins whereas artifacts do not. The Origin Problem contends that, (...) contra biocentrism, an entity’s origin is not relevant to whether that entity has moral status. The Normativity Problem is that biocentrists are preoccupied with accounting for the goods or interests of nonsentient organisms yet fail to establish why interests so construed confer moral status; biocentrism fails to bridge the good-ought gap. It is shown how these problems emerge in three prominent book-length works representative of the biocentrists’ positions over three decades: Paul Taylor’s Respect for Nature, Gary Varner’s In Nature’s Interests?, and Nicholas Agar’s Life’s Intrinsic Value. At minimum, these criticisms suggest that biocentrism is crucially incomplete as a moral framework at present and, optimistically, where more work remains to be done. If biocentrism really is dead, then moral status should be restricted to a more plausible locus such as sentience or rationality, the value of organisms needs a different expression, and environmental ethics needs an axiological foundation different than bare life.

Health care institutions, including Roman Catholic institutions, are in a time of crisis. This crisis may provide an important opportunity to reinvigorate Roman Catholic health care. The current health care crisis offers Roman Catholic health care institutions a special opportunity to rethink their fundamental commitments and to plan for the future. The author argues that what Catholic health care institutions must first do is articulate the nature of their identity and their commitments. By a renewed commitment to the praxis of (...) health care on their own distinctive terms, Roman Catholic health care institutions may reestablish a vision of human nature and human service in an increasingly secular society. Health care could then reclaim its place as a powerful setting for the expression of Roman Catholic faith, life and witness. (shrink)

On 26 July 2016, Satoshi Uematsu murdered 19 and injured 26 at a caregiving facility in Sagamihara, Japan, making it the country’s worst mass killing since WWII. In this article, I offer an analysis of the Sagamihara 19 massacre. I draw on the work of Julia Kristeva and Emmanuel Levinas to argue that claims about disability experience are insufficient to justify normative projects. In short, disability is normatively ambiguous.

Eukaryotes organize certain chromosomal intervals into domains capable of si lencing most genes. Examples of silencing domains include the HML/HMR loci and subtelomeric chromatin in yeast, the Barr body X chromosome in mammals, and the pericentric heterochromatin of Drosophila. Silencing chromatin is often correlated with more regularized nucleosomal array than that found in active chromatin, and transcriptional activators appear to be missing from their target sites in silent chromatin. In Drosophila, gene silencing by heterochromatin is often variegated, indicating that a (...) gene may escape silencing in some cells. In a recent study, Ahmad and Henikoff(1) show that a yeast activator can compete successfully with Drosophila heterochromatic silencing factors for target sites in DNA. This competition, together with developmental change in the stability of heterochromatin itself, decides the transcriptional state for a gene subject to heterochromatin repression.

Cet article est consacré au thème de la déshumanisation chez Simone Weil. Elle cherche à expliquer la facilité avec laquelle les individus sont dépouillés de leur humanité et traités comme de simples choses. La phénoménologie éthique d’Emmanuel Levinas est sollicitée pour éclairer les analyses weiliennes. L’accent est particulièrement mis sur l’importance de l’attention en éthique et sur la complexe et ambiguë conception weilienne de l’individu, entité à la fois personnelle et impersonnelle.This article focuses on dehumanization in the writings of Simone (...) Weil. She tries to explain why people are easily stripped of their humanity and treated like material objects. In the article a comparison is drawn between her analysis of dehumanization and Emmanuel Levinas’ phenomenology of ethics. The emphasis is put on the importance of attention in ethics and on Weil’s complex and ambiguous conception of the individual as a personal and impersonal entity. (shrink)

Some of the most celebrated images of nineteenth-century American photography emerged from government-sponsored geological surveys whose purpose was to study and document western territories. Timothy H. O'Sullivan and William Bell, two survey photographers who joined expeditions in the 1860s and 1870s, opened the eyes of nineteenth-century Americans to the western frontier. Highlighting a recent Smart Museum of Art acquisition, One/Many brings together an exquisite group of photographs by Bell and O'Sullivan. Particularly noteworthy are their photographic panoramas, assemblages of individual images (...) joined together to form a continuous, horizontal landscape view. These panoramas have not been exhibited in well over a century and have never before been published. For the first time, One/Many investigates their role and purpose both within and outside of the surveys, taking into account the larger context of nineteenth-century modes of viewing. The volume also allows the little-known Bell's work to be better understood next to that of his more famous colleague. (shrink)

Jean Mair, au début du XVIe siècle, entreprend de montrer que linfini existe en acte. Son traité De l'Infini prolonge les débats du XIVe siècle sur l'infini et le continu. Le problème de l' infini y est traité d'une manière principalement logique. L'infini est un terme qui a plusieurs sens selon son usage dans des propositions. La distinction centrale est celle de l'infini au sens catègorématique et de l'infini au sens synatégorématique. Mais si les auteurs du XIVe siècle admettent tous (...) l'infini au sens syncatêgorématique, la plupar récusent l'être en acte de l' infini au sens catègorématique. C'est à ce dernier point que Jean Mair consacre l'essentiel de sa réflexion. A l'intérieur d'un cadre qui reste aristotélicien par sa problématique d'ensemble et la formulation des questions, il renverse, grâce aux outils conceptuels de la logique terministe, une thèse centrale dans l'aristotélisme. Son traité contribue ainsi à développer l'idée que l'infini peut exister dans la nature. At the beginning of the 16th Century, Jean Mair set out to prove that the infinite exists Hot just potentially but actually. His treatise Propositum de infinito prolonged the 14th Century debates over the infinite and continuity, and it dealt logically with the problem of the infinite. The infinite is a term that has several meanings, depending upon its usage in propositions. The distinction between the categorematic and syncategorematic infinites is the central one in the treatise. If 14th Century authors by and large accepted the syncategorematic infinite, the majority challenged the existence of an actual infinite in the case of the categorematic infinite. Jean Mair devoted the bulk of his reflections to the latter situation. Within a framework that remained thoroughly Aristotelian, both in his overall problematic, as well as in the way he formulated questions, Mair overturned a central Aristotelian thesis, with the aid of conceptual tools from terminist logic. In this way his treatise contributed to the development of the idea that the infinite can exist in nature. (shrink)

Most epistemologists of testimony assume that testifying requires that the beliefs to which speakers attest are identical to the beliefs that hearers accept. I argue that this characterization of testimony is misleading. Characterizing testimony in terms of duplicating speaker/hearer belief unduly resticts the variety of beliefs that might be accepted from speaker testimony.

In the 1950's some prominent philosophers suggested a logical relation weaker than entailment between primarily descriptive statements and ethical conclusions. The paper revisits this suggestion. It examines four ways in which ethical statemnts can be supported by descriptions and evaluations. This provides a similarity bteween some kinds of reason-giving in ethics and familiar cases of logical inference, making it plausible to speak of a logic. The similarity however is limited, and the strength in ethics of descriptive reasons is never precise (...) and always somewhat contestable. (shrink)

In his masterly article, “Sir Arthur Eddington and the Physical World,” which appeared in the January 1934 issue of Philosophy, Dr. Stace has brought out a number of interesting points on which I should like to comment. However, as the main issues between Professor Stace and Professor Eddington are with regard to the physical world and reality, these will form the main topics of my remarks.

In this paper, I argue against the claim that in Plato's Republic the most important distinguishing feature between the philosopher and non-philosopher is that the philosopher has knowledge while the non-philosopher has, at best, true opinion. This claim is, in fact, inconsistent with statements Plato makes in later books of the Republic. I submit that the important distinction Plato makes concerns the type of knowledge possessed by the philosopher-ruler. As a result, we need to amend widely held scholarly interpretations of (...) important passages in the Republic ; most notably the passages containing the Sun, Line, and Cave. I consider the views of a number of important scholars and suggest a proposal that avoids this inconsistency with the text. An important consequence of my argument is that Philosophers are indeed not the only ones with knowledge in the Kallipolis. (shrink)

What rational foundation underlies argument-critical judgements? What are the canons of argument criticism and how are they to be "justified"? This paper explores an analogy between art- and argument-criticism and argues that the analogy promises not only to illuminate the nature of argument criticism and capture the central goals of instruction in informal logic, but also to resolve fundamental problems at the foundations of normative theory of argument concerning the "justification" of standards of reasoning.
