There is public support in the United States and Europe for accounting for animal welfare in national policies on food and agriculture. Although an emerging body of research has measured animals’ capacity to suffer, there has been no specific attempt to analyze how this information is interpreted by the public or how exactly it should be reflected in policy. The aim of this study was to quantify Americans’ preferences about farming methods and the suffering they impose on different species to (...) generate a metric for weighing the trade-offs between different approaches of promoting animal welfare. A survey of 502 residents of the United States was implemented using the online platform Mechanical Turk. Using respondent data, we developed the species-adjusted measure of suffering-years, an analogue of the disability-adjusted life year, to calculate the suffering endured under different farming conditions by cattle, pigs, and chickens, the three most commonly consumed animals. Nearly one-third of respondents reported that they believed animal suffering should be taken into account to a degree equal to or above human suffering. The 2016 suffering burden in the United States according to two tested conditions was approximately 66 million SAMYs for pigs, 156 million SAMYs for cattle, and 1.3 billion SAMYs for chickens. This calculation lends early guidance for efforts to reduce animal suffering, demonstrating that to address the highest burden policymakers should focus first on improving conditions for chickens.

In psychophysical experiments, the use of a psychophysical procedure of brightness/darkness cancellation shed light on interactions between spatial arrangement and figure–ground contrast in the perceptual filling in of achromatic and colored surfaces.Achromatic and chromatic Kanizsa squares with varying contrast, contrast polarity, and inducer spacingwere used to test how these factors interact in the perceptual filling in of surface brightness or darkness. The results suggest that the neuronal processing of surfaces with apparent contrast, leading to figure–ground segregation (i.e., perceptual organization), is (...) governed by mechanisms that integrate both luminance contrast and spatial information carried by the inducing stimuli, while discarding information on contrast polarity or color. The findings are discussed in relation to earlier observations on brightness assimilation and contrast. They support theories of nonantagonistic neural mechanisms suppressing local contrast or color signs in brightnessbased figure–ground percepts. Such mechanismsmight be necessary to cancel potentially conflicting polarities in geometricallycomplex visual stimuli so that perceptual filling in resulting in the most plausible representation of figure and ground can be achieved.

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.

The Repugnant Conclusion served an important purpose in catalyzing and inspiring the pioneering stage of population ethics research. We believe, however, that the Repugnant Conclusion now receives too much focus. Avoiding the Repugnant Conclusion should no longer be the central goal driving population ethics research, despite its importance to the fundamental accomplishments of the existing literature.

Jean-Luc Marion’s phenomenology reveals two attitudes regarding the classification of phenomena. On the one hand, they are classified by type. On the other, the “banality of saturation” reduces these types topossibleinterpretations, in which case saturation isn’t a qualitative rupture anymore, but a possible hermeneutic attitude to any phenomenon. Hence, there is, in Marion’s phenomenology, a tension between a metaphysical attitude that maintains categorial discontinuities, and a hermeneutic temptation driven by the recovery of quantitative continuities between all phenomena. Yet, Marion does (...) not push this quantitative temptation to its limits; he steps back in front of a specifically saturated phenomenon: the icon. (shrink)

We provide a simple translation of the satisfiability problem for regular grammar logics with converse into GF2, which is the intersection of the guarded fragment and the 2-variable fragment of first-order logic. The translation is theoretically interesting because it translates modal logics with certain frame conditions into first-order logic, without explicitly expressing the frame conditions. It is practically relevant because it makes it possible to use a decision procedure for the guarded fragment in order to decide regular grammar logics with (...) converse. The class of regular grammar logics includes numerous logics from various application domains. A consequence of the translation is that the general satisfiability problem for every regular grammar logics with converse is in EXPTIME. This extends a previous result of the first author for grammar logics without converse. Other logics that can be translated into GF2 include nominal tense logics and intuitionistic logic. In our view, the results in this paper show that the natural first-order fragment corresponding to regular grammar logics is simply GF2 without extra machinery such as fixed-point operators.

Local sustainable food systems have captured the popular imagination as a progressive, if not radical, pillar of a sustainable food future. Yet these grassroots innovations are embedded in a dominant food regime that reflects productivist, industrial, and neoliberal policies and institutions. Understanding the relationship between these emerging grassroots efforts and the dominant food regime is of central importance in any transition to a more sustainable food system. In this study, we examine the encounters of direct farm marketers with food safety (...) regulations and other government policies and the role of this interface in shaping the potential of local food in a wider transition to sustainable agri-food systems. This mixed methods research involved interview and survey data with farmers and ranchers in both the USA and Canada and an in-depth case study in the province of Manitoba. We identified four distinct types of interactions between government and farmers: containing, coopting, contesting, and collaborating. The inconsistent enforcement of food safety regulations is found to contain progressive efforts to change food systems. While government support programs for local food were helpful in some regards, they were often considered to be inadequate or inappropriate and thus served to coopt discourse and practice by primarily supporting initiatives that conform to more mainstream approaches. Farmers and other grassroots actors contested these food safety regulations and inadequate government support programs through both individual and collective action. Finally, farmers found ways to collaborate with governments to work towards mutually defined solutions. While containing and coopting reflect technologies of governmentality that reinforce the status quo, both collaborating and contesting reflect opportunities to affect or even transform the dominant regime by engaging in alternative economic activities as part of the ‘politics of possibility’. Developing a better understanding of the nature of these interactions will help grassroots movements to create effective strategies for achieving more sustainable and just food systems. (shrink)

Lacepède was a key figure in the French intellectual world from the Old Regime to the Restoration, sinc e he was not only a scientist, but also a musician, a writer, and a politician. His brilliant career is a good example of the progress of the social status of scientists in France around 1800. In the life sciences, he was considered the heir to Buffon and continued the latter’s Histoire naturelle, but he also borrowed ideas from anti-Buffonian scientists. He broached (...) many important subjects such as the nature of man, the classification of animals, the concept of species, and the history of the Earth. All these topics led to tensions in the French sciences, but Lacepède dealt with them in a consensual, indeed even ambiguous way. For example, he held transformist views, but his concept of evolution was far less precise and daring than Lamarck’s contemporaneous attempts. His somewhat confused eclecticism allowed him to be accepted by opposing camps of the French scientific community at that time and makes his case interesting for historians, since the opinions of such an opportunistic figure can illuminate the figure of the French intellectual better than more original works could do. In turn, Lacepède’s important social and scientific position gave his views a significant visibility. In this sense, his contributions probably exerted an influence, in particular with regard to the emergence of transformist theories. (shrink)

This paper empirically raises and examines the question of ‘conceptual control’: To what extent are competent thinkers able to reason properly with new senses of words? This question is crucial for conceptual engineering. This prominently discussed philosophical project seeks to improve our representational devices to help us reason better. It frequently involves giving new senses to familiar words, through normative explanations. Such efforts enhance, rather than reduce, our ability to reason properly, only if competent language users are able to abide (...) by the relevant explanations, in language comprehension and verbal reasoning. This paper examines to what extent we have such ‘conceptual control’ in reasoning with new senses. The paper draws on psycholinguistic findings about polysemy processing to render this question empirically tractable and builds on recent findings from experimental philosophy to address it. The paper identifies a philosophically important gap in thinkers’ control over the key process of stereotypical enrichment and discusses how conceptual engineers can use empirical methods to work around this gap in conceptual control. The paper thus empirically demonstrates the urgency of the question of conceptual control and explains how experimental philosophy can empirically address the question, to render conceptual engineering feasible as an ameliorative enterprise.

Pour la phénoménologie de Jean-Luc Marion, Descartes est le philosophe ayant achevé la métaphysique. Mais il faut entendre toute la polyphonie de ce terme. D’un côté, il l’a achevée au sens où il l’a parachevée, la portant à son sommet en fixant ses concepts et ses enjeux pour la modernité à venir. De l’autre, il l’a achevée en montrant ses brisures, la rendant caduque par la mise au jour de son dépassement possible selon deux concepts qui déterminent aussi deux moments (...) cartésiens : l’infini puis la chair. Cette ambivalence eu égard à la métaphysique (fixation puis dépassement), résonne dans la phénoménologie de la donation puisqu’elle détermine la mise en place de la distinction entre les phénomènes saturés et les phénomènes de droit commun. Ainsi, Descartes est utilisé comme le philosophe qui fixe les frontières, non seulement entre philosophie et métaphysique, mais aussi celles qui passent au cœur même de la phénoménologie. Pourtant, à de nombreuses reprises, Marion montre que cette fixation des frontières n’est pas aussi aisée à opérer qu’il n’y paraît, et qu’il y a un brouillage essentiel et originaire de celles-là. Pour la phénoménologie de la donation, Descartes est donc à la fois un repoussoir et un aimant, ce qu’il faut dépasser et ce à partir de quoi on le dépasse, ce qui disparaît dans la mort de la métaphysique, mais aussi ce qui s’attarde dans ce qui lui survit.

"There are seven chapters, addressing philosophical issues pertaining to death, the badness of death, time and death, ideas on immortality, near death experiences, and extending life through medical technology. The book is shorter, and less elaborate, than Kagan's Death. And it goes into more depth about a selection of central issues related to death and immortality than May's book. It gives an original take on various basic puzzles pertaining to death, and integrates a discussion of these philosophical issues with an (...) analysis of near-death experiences, as well as an exploration of contemporary efforts to extend life by heroic medical means"--.

It is often suggested that emotions are intrinsically normative or that they have conditions of correctness that are intrinsic. In order to assess this thesis, I consider whether the main argument in favor of the normativity of belief can be transposed to emotions. In the case of belief, the argument is that when we wonder whether to believe that p, we acknowledge that we must abide by some norms. This is understood as showing that these norms are intrinsic to the (...) concept of belief. In contrast, it appears that no similar constraint applies when we deliberate about emotions. Indeed, I argue that extrinsic norms are suf ficient to understand thoroughly the normativity of emotions. Therefore, the postulation of intrinsic norms or correctness conditions seems unmotivated. Worse, if emotions had intrinsic norms or correctness conditions, they would manifest themselves when we wonder whether an emotion is appropriate in this or that context. But they don’t. (shrink)

Subjectivism about well-being holds that an object contributes to one's well-being to the extent that one has a pro-attitude toward this object under certain conditions. Most subjectivists have contended that these conditions should be ideal. One reason in favor of this idea is that when people adapt their pro-attitudes to situations of oppression, the levels of well-being they may attain is diminished. Nevertheless, I first argue that appealing to idealized conditions of autonomy or any other condition to erase or replace (...) adaptive pro-attitudes is mistaken. Second, I show that the most natural version of subjectivism that does not appeal to any such idealizing condition can explain why the well-being of people having adaptive pro-attitudes should not be restricted to the fulfillment of these pro-attitudes. In sum, the existence of adaptive preferences does not militate in favor of the introduction of conditions of idealization but against it. (shrink)

'Beaucoup perçoivent, devant la progression de la possibilité pour l'individu d'affirmer sa singularité et sa volonté de bien-être, une progression de l'individualisme. Pour maintenir tant bien que mal un semblant de cohérence, ils sont alors obligés de minimiser, voire d'occulter, la progression de la solidarité dans le monde, aussi bien le développement des divers systèmes de protection sociale étatiques que le développement des aides interétatiques ou le développement des organisations non gouvernementales. Mais le concept d'individualisme ne décrit pas ce qui (...) effectivement se passe au niveau de l'individu, il ne fait que l'effleurer de son aile douloureuse et s'écraser contre la vitre du concept d'égoïsme. Il faut inventer un autre concept : ce sera l'individuité. Et alors tout devient plus cohérent. L'individuité, définie comme la désacralisation totale de tout groupe et la sacralisation à égalité de tout individu, est ce qui permet de rendre compte du fait que c'est justement parce que la civilisation se structure peu à peu autour de l'égo, que c'est justement parce qu'elle transfère peu à peu, des dieux aux individus, ses mouvements les plus centraux et ses perspectives les plus fondamentales, qu'elle fait alors croître sa capacité à générer de la solidarité et même de l'altruisme. Le regard humain, qui depuis toujours vacillait, à la fois se courbant vers le despotisme de sa terre et se perdant vers les mirages de l'au-delà, acquiert peu à peu la capacité d'enfin se stabiliser à hauteur d'humain, dans le regard de l'Autre. Vidant progressivement de leur substance les communautés identitaires au profit des individus qu'arbitrairement elles enclosent, déconstruisant progressivement les fausses transcendances au profit de l'autotranscendance de la conscience réflexive, faisant progressivement du Je le centre de l'univers, la civilisation se structure peu à peu autour du fait qu'il y a magnifiquement un nombre incommensurable de centres à l'univers, un par subjectivité. L'humanité n'avait toujours vécu qu'à l'ère des sacralités groupales, qu'à l'ère de la dialectique identitarisme-religion, et puis, d'abord par un frémissement il y a deux millénaires et demi, et se renforçant peu à peu au cours des siècles jusqu'à de nos jours entrer dans un vertige exponentiel, voilà qu'une nouvelle dynamique émerge qui renverse tout : l'individu s'émancipe. Une nouvelle ère anthropologique s'ouvre à nous, il fallait la nommer : l'ère de l'individuité sera, ici, peut-être ailleurs, son nom. Un nom est aussi un outil, il permettra de mieux conceptualiser ce changement, pour mieux l'accompagner, et pour l'accélérer. Car les forces réactionnaires sont là, puissantes, actives, qui le freinent. Le militarisme est l'archétype du vivre-ensemble tel que l'agençait l'ère des sacralités groupales, là où les individus ne sont que des fragments de groupes identitaires, d'insignifiantes munitions ne servant qu'à s'écraser, au mieux par terre, et le labour ainsi se fait, au pire contre celles des autres groupes identitaires, et la mort toujours triomphe : et ce monde affreux, bien qu'affreux, n'est pas facile à quitter, et le vivre-ensemble, bien que souffrant, ne se laisse pas facilement soigner, et le chemin sera alors encore long (peut-être même très long, mais peut-être pas tant que ça si l'on sait le penser) avant que chaque individu soit considéré comme un tout, avant que l'égalité ontologique remplace totalement les hiérarchies identitaires, avant que l'éthique du respect universel remplace totalement la morale sacrificielle, avant que l'humanité ait définitivement choisi entre l'individuité ou la guerre'."--Page 4 of cover.

Homeosis is a developmental abnormality corresponding to the transformation of a part of the body into another one. This term was introduced in 1894 by William Bateson, who aimed to make an inventory of all kinds of biological variation in order to understand how evolution proceeds. But, immediately afterwards experimental embryology, or Entwicklungsmechanik in Germany, adopted and redefined this term to refer to abnormal regenerations in which the newly developed organ was not identical to the initial one but rather resembled (...) another part of the body. At that time, many experimental embryologists, such as Wilhelm Roux, were calling for the elimination of any phylogenetic explanation of development and were attempting to promote more mechanistic, proximate explanations. Despite these recommendations, several biologists continued to account for developmental processes by turning to phylogeny instead of mechanical forces. The case of homeosis is representative. Indeed, abnormal regenerations were often seen as examples of atavisms, or recurrence of ancestral characteristics, and many embryologists appealed to Ernst Haeckel's 'fundamental biogenetic law' to explain these strange phenomena. The break between Haeckelian tradition and Entwicklungsmechanik is thus less radical than often assumed, and the homeosis concept represents one of the factors of this continuity. (shrink)

The article aims at assessing the strengths and weaknesses of the objections to Habermas’s epistemic conception of democracy raised by Thomas McCarthy in some of his essays. The author defends two ideas. First, he contends that McCarthy is mistaken in believing that democratic debates would not be a matter of consensus. In this regard, two arguments are raised, showing that the search for agreement and consensus by citizens in public forums can hardly be dismissed and that consensus can be invested (...) with many meanings in democratic life. Secondly, however, the author approves McCarthy when challenging Habermas’s epistemic claims regarding his theory of democracy. Not all democratic deliberations can be analysed in epistemic terms, in particular, debates on values. The pitfalls of any epistemic account of this form of deliberation are pointed out in the end of the essay. (shrink)

Hartry Field distinguished two concepts of type‐free truth: scientific truth and disquotational truth. We argue that scientific type‐free truth cannot do justificatory work in the foundations of mathematics. We also present an argument, based on Crispin Wright's theory of cognitive projects and entitlement, that disquotational truth can do justificatory work in the foundations of mathematics. The price to pay for this is that the concept of disquotational truth requires non‐classical logical treatment.

Like modal logic, temporal logic, and description logic, separation logic has become a popular class of logical formalisms in computer science, conceived as assertion languages for Hoare-style proof systems with the goal to perform automatic program analysis. In a broad sense, separation logic is often understood as a programming language, an assertion language and a family of rules involving Hoare triples. In this survey, we present similarities between separation logic as an assertion language and modal and temporal logics. Moreover, we (...) propose a selection of landmark results about decidability, complexity and expressive power. (shrink)

This study examined narrative identity in a group of 81 patients with schizophrenia and 50 healthy controls through the recall of self-defining memories. The results indicated that patients’ narratives were less coherent and elaborate than those of controls. Schizophrenia patients were severely impaired in the ability to make connections with the self and extract meaning from their memories, which significantly correlated with illness duration. In agreement with earlier research, patients exhibited an early reminiscence bump. Moreover, the period of the reminiscence (...) bump, which is highly relevant for identity development, was characterized by fewer achievements and more life-threatening event experiences, compared with controls. A negative correlation was found between negative symptoms, number of self-event connections and specificity of narratives. Our results suggest that schizophrenia patients have difficulties to organize and extract meaning from their past experiences in order to create coherent personal narratives. (shrink)

Además, busca mostrar cómo desde el arte, el proceso de la visibilidad es presentado como construcción del fenómeno que opera desde lo invisible.

This paper provides new tools for philosophical argument analysis and fresh empirical foundations for ‘critical’ ordinary language philosophy. Language comprehension routinely involves stereotypical inferences with contextual defeaters. J.L. Austin’s Sense and Sensibilia first mooted the idea that contextually inappropriate stereotypical inferences from verbal case-descriptions drive some philosophical paradoxes; these engender philosophical problems that can be resolved by exposing the underlying fallacies. We build on psycholinguistic research on salience effects to explain when and why even perfectly competent speakers cannot help making (...) stereotypical inferences which are contextually inappropriate. We analyse a classical paradox about perception, suggest it relies on contextually inappropriate stereotypical inferences from appearance-verbs, and show that the conditions we identified as leading to contextually inappropriate stereotypical inferences are met in formulations of the paradox. Three experiments use a forced-choice plausibility-ranking task to document the predicted inappropriate inferences, in English, German, and Japanese. The cross-linguistic study allows us to assess the wider relevance of the proposed analysis. Our findings open up new perspectives for ‘evidential’ experimental philosophy. (shrink)

This paper presents the hypothesis that concept possession is sufficient and necessary for self-consciousness. If this is true it provides a yardstick for gauging the validity of different research paradigms in which claims for self-consciousness in animals or human infants are made: a convincing demonstration of concept possession in a research subject, such as a display of inferential reasoning, may be taken as conclusive evidence of self-consciousness. Intuitively, there appears to be a correlation between intelligence in animals and the existence (...) of self-consciousness. I present three discussions to support the hypothesis: an analogy between perception and conception, where both are self-specifying; an argument that any web of concepts will always include the self-concept; and a fresh interpretation of Bermũdez showing how his theory of non-conceptual content provides strong support for the concept possession hypothesis.

Many philosophical thought experiments and arguments involve unusual cases. We present empirical reasons to doubt the reliability of intuitive judgments and conclusions about such cases. Inferences and intuitions prompted by verbal case descriptions are influenced by routine comprehension processes which invoke stereotypes. We build on psycholinguistic findings to determine conditions under which the stereotype associated with the most salient sense of a word predictably supports inappropriate inferences from descriptions of unusual (stereotype-divergent) cases. We conduct an experiment that combines plausibility ratings (...) with pupillometry to document this “salience bias.” We find that under certain conditions, competent speakers automatically make stereotypical inferences they know to be inappropriate.
