The European project European and Latin American Systems of Ethics Regulation of Biomedical Research Project (EULABOR) has carried out the first comparative analysis of ethics regulation systems for biomedical research in seven countries in Europe and Latin America, evaluating their roles in the protection of human subjects. We developed a conceptual and methodological framework defining ‘ethics regulation system for biomedical research’ as a set of actors, institutions, codes and laws involved in overseeing the ethics of biomedical research on humans. This (...) framework allowed us to develop comprehensive national reports by conducting semi-structured interviews to key informants. These reports were summarised and analysed in a comparative analysis. The study showed that the regulatory framework for clinical research in these countries differ in scope. It showed that despite the different political contexts, actors involved and motivations for creating the regulation, in most of the studied countries it was the government who took the lead in setting up the system. The study also showed that Europe and Latin America are similar regarding national bodies and research ethics committees, but the Brazilian system has strong and noteworthy specificities. (shrink)

Background Consent policies for post-mortem organ procurement (OP) vary throughout Europe, and yet no studies have empirically evaluated the ethical implications of contrasting consent models. To fill this gap, we introduce a novel indicator of governance quality based on the ideal of informed support, and examine national differences on this measure through a quantitative survey of OP policy informedness and preferences in seven European countries. -/- Methods Between 2017–2019, we conducted a convenience sample survey of students (n = 2006) in (...) Austria (AT), Belgium (BE), Denmark (DK), Germany (DE), Greece (GR), Slovenia (SI) and Spain (ES), asking participants about their donation preferences, as well as their beliefs and views about the policy in place. From these measures, we computed indices of informedness, policy support, and fulfilment of unexpressed preferences, which we compared across countries and consent systems. -/- Results Our study introduces a tool for analyzing policy governance in the context of OP. Wide variation in policy awareness was observed: Most respondents in DK, DE, AT and BE correctly identified the policy in place, while those in SI, GR and ES did not. Respondents in opt-out countries (AT, BE, ES and GR) tended to support the policy in place (with one exception, i.e., SI), whereas those in opt-in countries (DE and DK) overwhelmingly opposed it. These results reveal stark differences in governance quality across countries and consent policies: We found a preponderance of informed opposition in opt-in countries and a general tendency towards support–either informed or uninformed–in opt-out countries. We also found informed divergence in opt-in countries and a tendency for convergence–either informed or uninformed–among opt-out countries. -/- Conclusion Our study offers a novel tool for analyzing governance quality and illustrates, in the context of OP, how the strengths and weaknesses of different policy implementations can be estimated and compared using quantitative survey data.

This paper puts forward three critiques of pardo’s second-order proof rules thesis. The first criticism states that these rules are not suitable to guide the interpretation of standards of proof rules because they confuse matters of legal interpretation with matters of epistemology. The second criticism states that second-order proof rules are affected by the same indeterminacy problems they are designed to resolve, thereby rendering them unsuitable for the task they are purposely designed for. The third criticism renders pardo’s proposal redundant. (...) a reconceptualization of second-order proof rules is offered. (shrink)

The Uniform Determination of Death Act (UDDA) provides that “an individual who has sustained either (1) irreversible cessation of circulatory and respiratory functions or (2) irreversible cessation of all functions of the entire brain, including the brain stem, is dead.” We show that the UDDA contains two conflicting interpretations of the phrase “cessation of functions.” By one interpretation, what matters for the determination of death is the cessation of spontaneous functions only, regardless of their generation by artificial means. By the (...) other, what matters is the cessation of both spontaneous and artificially supported functions. Because each UDDA criterion uses a different interpretation, the law is conceptually inconsistent. A single consistent interpretation would lead to the conclusion that conscious individuals whose respiratory and circulatory functions are artificially supported are actually dead, or that individuals whose brain is entirely and irreversibly destroyed may be alive. We explore solutions to mitigate the inconsistency. (shrink)

Alireza Bagheri supports a policy on organ procurement where individuals could choose their own definition of death between two or more socially accepted alternatives. First, we claim that such a policy, without any criterion to distinguish accepted from acceptable definitions, easily leads to the slippery slope that Bagheri tries to avoid. Second, we suggest that a public discussion about the circumstances under which the dead donor rule could be violated is more productive of social trust than constantly moving the line (...) between life and death.

Goal: To assess public knowledge and attitudes towards the family’s role in deceased organ donation in Europe. -/- Methods: A systematic search was conducted in CINHAL, MEDLINE, PAIS Index, Scopus, PsycINFO, and Web of Science on December 15th, 2017. Eligibility criteria were socio-empirical studies conducted in Europe from 2008 to 2017 addressing either knowledge or attitudes by the public towards the consent system, including the involvement of the family in the decision-making process, for post-mortem organ retrieval. Screening and data collection (...) were performed by two or more independent reviewers for each record. -/- Results: Of the 1482 results, 467 studies were assessed in full-text form, and 33 were included in this synthesis. When the deceased has not expressed any preference, a majority of the public support the family's role as a surrogate decision-maker. When the deceased expressly consented, the respondents' answers depend on whether they see themselves as potential donors or as a deceased's next-of-kin. Answers also depend on the relationship between the deceased and the decision-maker(s) within the family, and on their ethnic or cultural background. -/- Conclusions: Public views on the authority of the family in organ donation decision-making require further research. A common conceptual framework and validated well-designed questionnaires are needed for future studies. The findings should be considered in the development of Government policy and guidance regarding the role of families in deceased organ donation. (shrink)

[ENGLISH] This article discusses the potential of synthetic biology to address fundamental questions in the philosophy of biology regarding the nature of life and biological functions. Synthetic biology aims to reduce living organisms to their simplest forms by identifying the minimal components of a cell and also to create novel life forms through genetic reprogramming, biobrick assembly, or novel proteins. However, the technical success of these endeavors does not guarantee their conceptual success in defining life. There is a lack of (...) consensus among researchers on how to define and classify the entities produced in the lab, whether they should be considered living or categorized differently. The criteria for minimal cells and minimal life are subject to arbitrary choices and varying interpretations. The concept of function, crucial to synthetic biology, is also difficult to define. The article highlights the need to consider the minimal set of functions that characterize life before determining the smallest genomes that code for those functions. The arbitrary nature of defining both life and function complicates the understanding and classification of these entities. The article suggests that the traditional dichotomy between the living and the non-living may no longer be valid and that the concept of life itself may not require precise scientific definition. As synthetic biology advances, the article emphasizes the importance of redefining or constructing new categories to encompass the expanding possibilities and creations in the field. The ability to create new life forms raises questions about recognition, identification, and ethical implications, requiring a conceptual and philosophical engagement beyond the technical achievements of synthetic biology. -/- [FRENCH] L'article aborde le potentiel de la biologie synthétique pour répondre à des questions fondamentales de la philosophie de la biologie concernant la nature de la vie et des fonctions biologiques. La biologie synthétique vise à réduire les organismes vivants à leurs formes les plus simples en identifiant les composants minimaux d'une cellule et à créer de nouvelles formes de vie grâce à la reprogrammation génétique, à l'assemblage de biobriques ou à des protéines nouvelles. Cependant, le succès technique de ces approches ne garantit pas leur réussite conceptuelle dans la définition de la vie. Il n'y a pas de consensus parmi les chercheurs sur la façon de définir et de classer les entités produites en laboratoire, qu'elles doivent être considérées comme vivantes ou catégorisées différemment. Les critères des cellules minimales et de la vie minimale sont soumis à des choix arbitraires et à des interprétations variables. La notion de fonction, essentielle en biologie synthétique, est également difficile à définir. L'article met en évidence la nécessité de prendre en compte l'ensemble minimal de fonctions qui caractérisent la vie avant de déterminer les plus petits génomes qui codent ces fonctions. La nature arbitraire de la définition de la vie et de la fonction complique la compréhension et la classification de ces entités. L'article suggère que la dichotomie traditionnelle entre le vivant et le non-vivant pourrait ne plus être valable et que le concept même de vie ne nécessite pas une définition scientifique précise. À mesure que la biologie synthétique progresse, l'article souligne l'importance de redéfinir ou de construire de nouvelles catégories pour englober les possibilités et créations croissantes dans le domaine. La capacité à créer de nouvelles formes de vie soulève des questions de reconnaissance, d'identification et d'implications éthiques, nécessitant une réflexion conceptuelle et philosophique au-delà des avancées techniques de la biologie synthétique.

Finality, design and purpose have started to be excluded from the language of the natural sciences since the XVIIth century. Darwin succeeded in excluding them from his theory of evolution appealing to a blind and mechanical natural selection. Today, the most usual definitions for the concept of biological function take for granted that functions: 1) are not dependent on a goal; 2) are not dependent on observers, but only on nature; 3) are explicable in causal terms, either with reference to (...) the causal history of the organ (etiological definition), or with reference to its present structure and causal capabilities (dispositional definition). However, we shall see that such presuppositions cannot take into account the normative character of the concept of biological function. We show that a generalization of the concept of scientific objectivity lets us affirm that functions: 1’) are dependent on a goal; 2’) are dependent on both observers and nature; 3’) cannot be reduced to causality, nor break the laws of physics; and yet, 4) are truly objective.

Families play an essential role in deceased organ procurement. As the person cannot directly communicate his or her wishes regarding donation, the family is often the only source of information regarding consent or refusal. We provide a systematic description and analysis of the different roles the family can play, and actions the family can take, in the organ procurement process across different jurisdictions and consent systems. First, families can inform or update healthcare professionals about a person’s donation wishes. Second, families (...) can authorize organ procurement in the absence of deceased’s preferences and the default is not to remove organs, and oppose donation where there is no evidence of preference but the default is to presume consent; in both cases, the decision could be based on their own wishes or what they think the deceased would have wanted. Finally, families can overrule the known wishes of the deceased, which can mean preventing donation, or permitting donation when the deceased refused it. We propose a schema of 4 levels on which to map these possible family roles: no role, witness, surrogate, and full decisional authority. We conclude by mapping different jurisdictions onto this schema to provide a more comprehensive understanding of the consent system for organ donation and some important nuances about the role of families. This classificatory model aims to account for the majority of the world’s consent systems. It provides conceptual and methodological guidance that can be useful to researchers, professionals, and policymakers involved in organ procurement. (shrink)

The classification of preserved hypothalamic activity in brain death and brainstem death as functional or non-functional has become a subject of debate. While proponents of the neurological criterion claim that these activities lack functional significance (Shemie et al. 2014), Nair-Collins and Joffe (2023) argue for their functional physiological role. However, the interpretation of the term "function" within the medico-legal framework, where death is characterized by the irreversible cessation of all brain functions, remains unclear. -/- My intention here is not to (...) engage in a debate over the validity of different viewpoints regarding the functional significance of preserved activities in the hypothalamus or the heart. Rather, I aim to highlight the critical importance of exploring and defining the concept of function in medicine, which currently lacks clarity. My point is that, whatever our position in the brain death debate, reaching a consensus on this conceptual matter would minimize misunderstandings and establish a robust foundation for further insightful analysis.

Laura Specker Sullivan (2022) makes a fairly compelling case for the value of the perspectives of Buddhist practitioners in neuroethics. In this study, Tibetan Buddhist monks have been asked, among other things, whether consciousness, in brain-injured patients in a minimally conscious state, entails a duty to preserve life. In our view, some of the participants’ responses could be used to inform the bioethical debate on death determination.

Since 1968, the irreversible loss of functioning of the whole brain, called brain death, is assimilated to individual’s death. The almost universal acceptance of this neurological criterion of death had decisive consequences for the contemporary medicine, such as the withdrawal of mechanical ventilation in these patients and organ retrieval for transplantation. The new criterion was successfully accepted in part because the assimilation of brain death state to death was presented by medicine --and acritically assumed by most of societies-- as a (...) scientific and objective fact. Nevertheless, many people do not think that the patients suffering brain death are actually dead. We show here that those people are not necessarily wrong. It can be argued that, in fact, the justification of the neurological criterion is not scientific but moral. We outline the thesis that the problem surrounding the vital status of brain dead patients is due to a confusion between factual and normative questions. Furthermore, we claim that the donation of organs and the withdrawal of life-support could be ethically acceptable even if the patients suffering brain death are considered as alive. As an alternative to the dead donor rule, we propose a justification for organ donation of brain-dead patients based on the (moral) concepts of harm and consent : what truly justifies the procurement of organs on those patients is not that they are dead, but that they wish to donate their organs and that, since they have irreversibly lost their brain, they cannot be harmed.

What role does the wild duck play in Ibsen's famous drama? I argue that, besides mirroring the fate of the human cast members, the duck is acting as animal subject in a quasi-experiment, conducted in a private setting. Analysed from this perspective, the play allows us to discern the epistemological and ethical dimensions of the new scientific animal practice (systematic observation of animal behaviour under artificial conditions) emerging precesely at that time. Ibsen's play stages the clash between a scientific and (...) a romantic understanding of animals that still constitutes the backdrop of most contemporary debates over animals in research. Whereas the scientific understanding reduces the animal's behaviour, as well as its environment, to discrete and modifiable elements, the romantic view regards animals as being at one with (or violently disconnected from) their natural surroundings.

Background: Several countries have recently changed their model of consent for organ donation from opt-in to opt-out. We undertook a systematic review to determine public knowledge and attitudes towards these models in Europe. Methods: Six databases were explored between 1 January 2008 and 15 December 2017. We selected empirical studies addressing either knowledge or attitudes towards the systems of consent for deceased organ donation by lay people in Europe, including students. Study selection, data extraction, and quality assessment were conducted by (...) two or more reviewers independently. Findings: Awareness of the consent model was lower in opt-out countries than in opt-in countries. A majority of the public agrees with opt-in, regardless of the law in their own country. There are ambivalent attitudes regarding the opt-out system. The public tend to prefer opt-in and mandatory choice over opt-out when several options are offered. Interpretation: The assumption that people in opt-out countries are aware of the legal requirements to be excluded from the pool of potential donors is not supported by the results of this review. This is a concern, since ignorance hinders people's autonomy regarding organ donation decision-making. Higher awareness of consent model in opt-in countries may reflect greater efforts to inform the public through campaigns to motivate donation. Legal moves towards opt-out are at odds with people's expressed preferences. Main limitations of this review are the lack of data from some countries, study population heterogeneity, and methodological shortcomings. (shrink)

Friedrich Engels’ dialectical assessment of modern science resulted from his fascination with the natural sciences in combination with his resurging interest in the work of “old Hegel.” Engels became especially interested in what he saw as the molecular essence of life, namely proteins or, more specifically, albumin, seeing life as the mode of existence of these enigmatic substances. Hegelian dialectics is crucial for a dialectical materialist understanding of contemporary technoscience. The dialectical materialist understanding of technoscience as a research practice builds (...) on Engels, but also on later authors who were inspired by his writings, e.g., life scientists such as Haldane and Bernal. Considering the criticism raised against Engels’ dialectics by 20th-century Marxists, a dialectical diagnostic of contemporary technoscience can be achieved, which shifts the focus from artificial albumin as “living matter” to contemporary research on synthetic cells.

This paper subjects Dan Brown’s most recent novel Origin to a philosophical reading. Origin is regarded as a literary window into contemporary technoscience, inviting us to explore its transformative momentum and disruptive impact, focusing on the cultural significance of artificial intelligence and computer science: on the way in which established world-views are challenged by the incessant wave of scientific discoveries made possible by super-computation. While initially focusing on the tension between science and religion, the novel’s attention gradually shifts to the (...) increased dependence of human beings on smart technologies and artificial intelligence. Origin’s message, I will argue, reverberates with Oswald Spengler’s The Decline of the West, which aims to outline a morphology of world civilizations. Although the novel starts with a series of oppositions, most notably between religion and science, the eventual tendency is towards convergence, synthesis and sublation, exemplified by Sagrada Família as a monumental symptom of this transition. Three instances of convergence will be highlighted, namely the convergence between science and religion, between humanity and technology and between the natural sciences and the humanities. (shrink)

The work of Emmanuel Levinas has been both abundantly recognized and criticized in moral philosophy. This Janus-faced attitude is also present in ecological theories, which find fertile ground in Levinas’ thought without being able to explain its apparent anthropocentrism. Opposing hermeneutical paths tend to focus either on otherness as an absolute alterity, implying a potentially unlimited responsibility for all alterities, or on otherness as a re-foundation of humanism, leading to the conclusion that responsibility is unlimited only among humans. Here I (...) seek to disentangle Levinas from these two extreme interpretations, first by reviewing ecological readings of his philosophy, in both the Francophone and Anglophone spheres, and second by analyzing specific Levinasian terms that might be particularly helpful for a non-anthropocentric or deep ecology. The main results of this investigation are a distinction between the ethics of responsibility and the ethics of vulnerability, an explanation of Levinasian compulsory or methodological humanism, and a schematic model of sensibility as enjoyment/vulnerability capable of supporting deep ecology without the traditional notions of free will, rights, or values.

50 years after its introduction, brain death remains controversial among scholars. The debates focus on one question: is brain death a good criterion for determining death? This question has been answered from various perspectives: medical, metaphysical, ethical, and legal or political. Most authors either defend the criterion as it is, propose some minor or major revisions, or advocate abandoning it and finding better solutions to the problems that brain death was intended to solve when it was introduced. Here I plead (...) for a different approach that has been overlooked in the literature: the philosophy of science approach. Some scholars claim that human death is a matter of fact, a biological phenomenon whose occurrence can be determined empirically, based on science. We should take this claim seriously, whether we agree with it or not. The question is: how do we know that human death is a scientific matter of fact? Taking the philosophy of science approach means, among other things, examining how the determination of human death became an object of scientific inquiry, exploring the nature of the brain death criterion itself, and analysing the meaning of its core concepts such as “irreversibility” and “functions”.

Do psychological traits predict philosophical views? We administered the PhilPapers Survey, created by David Bourget and David Chalmers, which consists of 30 views on central philosophical topics (e.g., epistemology, ethics, metaphysics, philosophy of mind, and philosophy of language) to a sample of professional philosophers (N = 314). We extended the PhilPapers survey to measure a number of psychological traits, such as personality, numeracy, well-being, lifestyle, and life experiences. We also included non-technical ‘translations’ of these views for eventual use in other (...) populations. We found limited to no support for the notion that personality or demographics predict philosophical views. We did, however, find that some psychological traits were predictive of philosophical views, even after strict correction for multiple comparisons. Findings include: higher interest in numeracy predicted physicalism, naturalism, and consequentialism; lower levels of well-being and higher levels of mental illness predicted hard determinism; using substances such as psychedelics and marijuana predicted non-realist and subjectivist views of morality and aesthetics; having had a transformative or self-transcendent experience predicted theism and idealism. We discuss whether or not these empirical results have philosophical implications, while noting that 68% of our sample of professional philosophers indicated that such findings would indeed have philosophical value.

This dissertation focuses on teleology and functions in biology. More precisely, it focuses on the scientific legitimacy of teleofunctional attributions and explanations in biology. It belongs to a multi-faceted debate that can be traced back to at least the 1970s. One aspect of the debate concerns the naturalization of functions. Most authors try to reduce, translate or explain functions and teleology in terms of efficient causes so that they find their place in the framework of the natural sciences. Our approach (...) here is radically different, as we question the premise that teleological explanations are disguised causal explanations. On the contrary, we defend that they are acceptable in natural sciences and in biology in particular. We challenge the idea that teleological explanations are immature causal explanations, as well as the idea that teleology and functions are some sort of intentional explanations. We therefore reject the accusations of anthropomorphism, vitalism and finalism. On the contrary, we defend that teleology, causality and intentionality correspond to different, autonomous and complementary modes of representation of the outside world. -/- ———[FRANÇAIS]——— -/- Ce travail de thèse porte sur la téléologie et les fonctions en biologie. Plus précisément, il porte sur la légitimité scientifique des attributions et des explications téléofonctionnelles en biologie. Il s’inscrit dans le cadre d’un débat à plusieurs facettes que l’on peut faire remonter au moins jusqu’aux années 1970 et qui est encore très actif aujourd’hui. L’un des aspects du débat porte sur la naturalisation des fonctions, c’est-à-dire sur la manière de les réduire, de les traduire ou de les expliciter en termes de causes efficientes de sorte qu’elles trouvent leur place dans le cadre des sciences de la nature. Notre approche ici est radicalement différente, car nous remettons en question la prémisse selon laquelle les explications téléologiques seraient des explications causales déguisées. Nous défendons au contraire qu’elles sont acceptables en tant que telles aussi bien de façon générale que dans le domaine scientifique et en particulier en biologie. De façon générale, nous remettons en question l’idée selon laquelle la pensée téléologique serait une pensée causale immature, ainsi que sa dépendance présumée vis-à-vis de la psychologie, c’est-à-dire de l’intentionnalité. Nous rejetons donc les accusations d’anthropomorphisme, de vitalisme et de finalisme formulées contre elle. Nous défendons au contraire que la téléologie, la causalité et l’intentionnalité correspondent à des modes différents, autonomes et complémentaires de représentation du monde extérieur. (shrink)

Objectives To increase postmortem organ donation rates, several countries are adopting an opt-out (presumed consent) policy, meaning that individuals are deemed donors unless they expressly refused so. Although opt-out countries tend to have higher donation rates, there is no conclusive evidence that this is caused by the policy itself. The main objective of this study is to better assess the direct impact of consent policy defaults per se on deceased organ recovery rates when considering the role of the family in (...) the decision-making process. This study does not take into account any indirect effects of defaults, such as potential psychological and behavioural effects on individuals and their relatives. -/- Design Based on previous work regarding consent policies, we created a conceptual model of the decision-making process for deceased organ recovery that included any scenario that could be directly influenced by opt-in or opt-out policies. We then applied this model to internationally published data of the consent process to determine how frequently policy defaults could apply. -/- Main outcome measures We measure the direct impact that opt-in and opt-out policies have per se on deceased organ recovery. -/- Results Our analysis shows that opt-in and opt-out have strictly identical outcomes in eight out of nine situations. They only differ when neither the deceased nor the family have expressed a preference and defaults therefore apply. The direct impact of consent policy defaults is typically circumscribed to a range of 0%–5% of all opportunities for organ recovery. Our study also shows that the intervention of the family improves organ retrieval under opt-in but hinders it under opt-out. -/- Conclusions This study may warn policy makers that, by emphasising the need to introduce presumed consent to increase organ recovery rates, they might be overestimating the influence of the default and underestimating the power granted to families.

In this paper, I will reread the history of molecular genetics from a psychoanalytical angle, analysing it as a case history. Building on the developmental theories of Freud and his followers, I will distinguish four stages, namely: (1) oedipal childhood, notably the epoch of model building (1943–1953); (2) the latency period, with a focus on the development of basic skills (1953–1989); (3) adolescence, exemplified by the Human Genome Project, with its fierce conflicts, great expectations and grandiose claims (1989–2003) and (4) (...) adulthood (2003–present) during which revolutionary research areas such as molecular biology and genomics have achieved a certain level of normalcy—have evolved into a normal science. I will indicate how a psychoanalytical assessment conducted in this manner may help us to interpret and address some of the key normative issues that have been raised with regard to molecular genetics over the years, such as ‘relevance’, ‘responsible innovation’ and ‘promise management’.

Is the boundary between the normal and the pathological real or fiction? Are health and disease just a matter of fact or are they value-laden? Here we present some examples of how alleged diseases can be invented and propagated by the industry (disease mongering) or by the methodology of medical science itself. We show that the boundary between health and disease is blurred and depends on individual and social representations, culture relative ways of categorising things and people, and by the (...) society’s degree of medicalisation. However, we do not mean that it is not real, rather that it is more complex than expected, as the subjectivity of social constructions and individual experiences makes them no less real. Finally, we conclude that health and disease belong to both objective and subjective kinds of reality, so the fictional can be real. (shrink)

With increased visibility of trans people comes increased philosophical interest in gendered language. This chapter aims to look at the research on gendered language in analytic philosophy of language so far, which has focused on two concerns: (1) determining how to define gender terms like ‘man’ and ‘woman’ such that they are trans inclusive and (2) if, or to what extent, we should use gendered language at all. We argue that the literature has focused too heavily on how gendered language (...) can harm trans people, and has not considered how trans people use gendered language to create meaning and joy for ourselves. Pulling from the literature in sociolinguistics, we look at examples of how trans people use language to make their lives better by gaining recognition, playing with gendered language, finding joy in gendered language, and taking control of definitional power, concluding that debates about gendered language need to consider not only how such language harms trans people but also how trans people use it for our own liberation.

Several European countries are approving legislative reforms moving to a presumed consent system in order to increase organ donation rates. Nevertheless, irrespective of the consent system in force, family's decisional capacity probably causes a greater impact on such rates. In this contribution we have developed a systematic methodology in order to analyse and compare European organ procurement laws, and we clarify the weight given by each European law to relatives' decisional capacity over individual's preferences (expressed or not while alive) regarding (...) the destination of his or her organs after death. In this sense, the results constitute the first comprehensive and comparative legislative mapping on European transplantation laws. (shrink)

This paper analyses the technoscientific objective of building a synthetic cell from a Jungian perspective. After decades of fragmentation and specialisation, the synthetic cell symbolises a turn towards restored wholeness, both at the object pole and at the subject pole. From a Jungian perspective, it is no coincidence that visual representations of synthetic cells often reflect an archetypal, mandala-like structure. As a symbol of restored unity, the synthetic cell mandala compensates for technoscientific fragmentation via active imagination, providing a visual aid (...) for the technoscientific turn towards reintegration. Although the biotechnological desire to reconstruct life in vitro has been compared to alchemy before, a Jungian analysis allows us to make this comparison more specific and precise. The problem of archetypal images, however, is that alluring prospects of reintegration may underestimate and obfuscate the deficiencies and tensions at work in the current situation. As a projection of a future wholeness, it fosters optimism, but may also function as a misleading façade, covering up collisions and complexities. This can be averted by the conscious employment of the mandala as a symbolic scaffold fostering processes of individuation and working through. (shrink)

ABSTRACT This article interprets a recently recovered manuscript, Tratado de astronomía y la reformaçión del tiempo, composed by Antonio Sánchez in New Granada c.1696, in the context of the Spanish and Renaissance cosmographies. Sánchez’s Tratado proposes a spherical astronomy, in which celestial bodies – including comets — move in orbs containing pyramidal knots that explain the changing speed observed in the motion of planets. From this astronomy and following the peninsular style of repertorios, Sánchez derives two major conclusions: the corrected (...) length of the solar year and a revised birth date of Jesus. Taking as center of reference Vélez, where Sánchez was based, these claims led to conclusions in domains ranging from calendric astronomy to eschatology, including the incorporation of the indigenous peoples into salvation narrative and a demonstration of the arrangement of the celestial orbs at the Last Judgment. Sánchez’s Tratado constitutes an expansion of the Spanish mathematical cosmography that sheds light on the production of knowledge in the Spanish-American world and, at the same time, provides elements to reassess our understanding of the global circulation of Renaissance and early modern ideas.

The counter majoritarian difficulty is one of the main objections against the judicial review. In this paper, this objection is analyzed from the standpoint of the norm formulation/norm distinction. By stressing the distinc- tion between norm formulations and norms, I claim that when judicial review prevents the application of a norm to an individual case the counter majoritarian difficulty objection does not hold.

In the field of Evidence Law the relation between truth and law has been a somewhat non- debated topic in the past years. It is a given that such a connection exists and, it is understood as the notion of the ascertainment of the truth of disputed questions of fact through legal evidence. The thesis that I have reconstructed in this paper has been presented by Prof. Jordi Ferrer who grounds the connection between truth and law in the role of (...) the legal system as a tool for guiding the behavior of the governed. I call this thesis the theory of the structural clause of truth. In this paper I shall present a possible reconstruction of this theory, I shall raise two objections against it and I shall present five possible interpretations of the relation between truth and law.

This paper analyses the arguments for and against what we have called automatic organ procurement model in relation to the organs of the deceased. For this purpose, this work provides empirical evidence to assess the potential impact of this model on donation rates and on public opinion. Specifically, we examine first the reasons supporting this model, with special reference to utilitarian and justice arguments. On the other hand, we analyse both the approaches based on the violation of pre mortem and (...) post mortem interests opposing this theoretical model and the rejection the model would generate in the population. Finally, we point out the aspects that, in our opinion, should be exhaustively regulated if this model were implemented. In particular, we refer to the legal status of the human body, the treatments for end-of-life patients, the incentives for health professionals and the recognition of the right to conscientious objection.

Altruism and solidarity are concepts that are closely related to organ donation for transplantation. On the one hand, they are typically used for encouraging people to donate. On the other hand, they also underpin the regulations in force in each country to different extents. They are often used indistinctly and equivocally, despite the different ethical implications of each concept. This paper aims to clarify to what extent we can speak of altruism and solidarity in the predominant models of organ donation. (...) It also raises the ethical question of whether these categories are adequate as a basis for such models, bearing in mind that organs are a scarce resource and that a shortage of them may mean that fewer lives are saved or improved.

Many current problems surrounding science revolve around the complex epistemological framework that shapes a new vision of knowledge about reality. The traditional epistemological positions are characterized by the explanation of nature by means of concatenated facts; that is, as bricks attached to each other giving shape to the edifice of science. A conception of this nature showed that the idea of certainty was nothing more than a mere illusion, opening the way, on the contrary, to the idea of the uncertainty (...) of knowledge based on the descriptions of quantum physics, also a product of the non-reductionist conception of reality, thus criticizing the specular representation. This article addresses the main problems surrounding the critical conceptions that the emerging epistemology reveals about knowledge, pointing towards a much more complex vision of reality. (shrink)

There is a widespread belief that for their own safety and for the protection of wildlife, cats should be permanently kept indoors. Against this view, I argue that cat guardians have a duty to provide their feline companions with outdoor access. The argument is based on a sophisticated hedonistic account of animal well-being that acknowledges that the performance of species-normal ethological behavior is especially pleasurable. Territorial behavior, which requires outdoor access, is a feline-normal ethological behavior, so when a cat is (...) permanently confined to the indoors, her ability to flourish is impaired. Since cat guardians have a duty not to impair the well-being of their cats, the impairment of cat flourishing via confinement signifies a moral failing. Although some cats assume significant risks and sometimes kill wild animals when roaming outdoors, these important considerations do not imply that all cats should be deprived of the opportunity to access the outdoors. Indeed, they do not, by themselves, imply that any cat should be permanently kept indoors. (shrink)

In this article, I examine the moral dimensions of gender affirmation. I argue that the moral value of gender affirmation is rooted in what Iris Murdoch called loving attention. Loving attention is central to the moral value of gender affirmation because such affirmation is otherwise too fragile or insincere to have such value. Moral reasons to engage in acts that gender affirm derive from the commitment to give and express loving attention to trans people as a way of challenging their (...) marginalization. In the latter part of the paper, I will discuss how my arguments bear on recent arguments by Robin Dembroff and Daniel Wodak (2018) on the use of gender-neutral language. They argue that we have a duty not to use gender-specific pronouns for anyone. Their conclusion turns, in part, on a rejection of gender affirmation as a moral duty. The value of gender affirmation, rooted in our moral perception of trans people, should make us skeptical of this conclusion, in favor of a more nuanced and pluralistic approach to the ethics of gendering.

When we perceive an object, we perceive the object from a perspective. As a consequence of the perspectival nature of perception, when we perceive, say, a circular coin from different angles, there is a respect in which the coin looks circular throughout, but also a respect in which the coin's appearance changes. More generally, perception of shape and size properties has both a constant aspect—an aspect that remains stable across changes in perspective—and a perspectival aspect—an aspect that changes depending on (...) one's perspective on the object. How should we account for the perspectival aspect of spatial perception? We present a framework within which to discuss the perspectival aspect of perception and put forward three desiderata that any account of the perspectival aspect of perception should satisfy. We discuss views on which the perspectival aspect of perception is analyzed in terms of constitutively mind-dependent appearance properties as well as views on which the perspectival aspect of perception is analyzed in terms of representations of mind-independent perspectival properties.

A prominent view holds that perception and memory are distinguished at least partly by their temporal orientation: Perception functions to represent the present, while memory functions to represent the past. Call this view perceptual presentism. This chapter critically examines perceptual presentism in light of contemporary perception science. I adduce evidence for three forms of perceptual sensitivity to the past: (i) shaping perception by past stimulus exposure, (ii) recruitment of mnemonic representations in perceptual processing, and (iii) perceptual representation of present objects (...) as possessing past properties. I argue that forms (i) and (ii) are consistent with perceptual presentism, while form (iii) poses a genuine threat to the view. While the empirical case for form (iii) remains inconclusive, I suggest that the most serious challenges to perceptual presentism derive from representations that integrate mnemonic and present-tensed elements in the performance of canonical perceptual functions, such as perceiving object continuity over time.

The ability to perceive the shapes of things as enduring through changes in how they stimulate our sense organs is vital to our sense of stability in the world. But what sort of capacity is shape constancy, and how is it reflected in perceptual experience? This paper defends a pluralist account of shape constancy: There are multiple kinds of shape constancy centered on geometrical properties at various levels of abstraction, and properties at these various levels feature in the content of (...) perceptual experience, governing patterns of apparent shape similarity. I propose that the varieties of shape constancy are subserved by the syntactic complexity of perceptual shape representations. By assigning discrete constituents to various abstract shape parameters, these representations attune us to the preservation of certain abstract shape properties through changes in more determinate shape properties. Finally, I draw broader lessons concerning the nature and function of perceptual constancy. (shrink)

Understanding everyday behavior relies heavily upon understanding our ability to improvise, how we are able to continuously anticipate and adapt in order to coordinate with our environment and others. Here we consider the ability of musicians to improvise, where they must spontaneously coordinate their actions with co-performers in order to produce novel musical expressions. Investigations of this behavior have traditionally focused on describing the organization of cognitive structures. The focus, here, however, is on the ability of the time-evolving patterns of (...) inter-musician movement coordination as revealed by the mathematical tools of complex dynamical systems to provide a new understanding of what potentiates the novelty of spontaneous musical action. We demonstrate this approach through the application of cross wavelet spectral analysis, which isolates the strength and patterning of the behavioral coordination that occurs between improvising musicians across a range of nested time-scales. Revealing the sophistication of the previously unexplored dynamics of movement coordination between improvising musicians is an important step towards understanding how creative musical expressions emerge from the spontaneous coordination of multiple musical bodies.

This article develops a view of shape representation both in visual experience and in subpersonal visual processing. The view is that, in both cases, shape is represented in a ‘layered’ manner: an object is represented as having multiple shape properties, and these properties have varying degrees of abstraction. I argue that this view is supported both by the facts about visual phenomenology and by a large collection of evidence in perceptual psychology. Such evidence is provided by studies of shape discriminability, (...) apparent motion, multiple-object tracking, and structure-from-motion. Recent neuroscientific work has also corroborated this psychophysical evidence. Finally, I draw out implications of the layered view for processes of concept acquisition. 1 Introduction2 Metric Properties andShape Properties3 Metric Views4 Against Metric Views of Visual Shape Experience5 The Visual System Uses Abstract Shape Properties6 Against Metric Views of Visual Shape Representation7 Neural Underpinnings of Abstract Shape Perception8 Implications.

Wittgenstein’s concepts shed light on the phenomenon of schizophrenia in at least three different ways: with a view to empathy, scientific explanation, or philosophical clarification. I consider two different “positive” wittgensteinian accounts―Campbell’s idea that delusions involve a mechanism of which different framework propositions are parts, Sass’ proposal that the schizophrenic patient can be described as a solipsist, and a Rhodes’ and Gipp’s account, where epistemic aspects of schizophrenia are explained as failures in the ordinary background of certainties. I argue that (...) none of them amounts to empathic-phenomenological understanding, but they provide examples of how philosophical concepts can contribute to scientific explanation, and to philosophical clarification respectively.

Causal closure arguments against interactionist dualism are currently popular amongst physicalists. Such an argument appeals to some principles of the causal closure of the physical, together with certain other premises, to conclude that at least some mental events are identical with physical events. However, it is crucial to the success of any such argument that the physical causal closure principle to which it appeals is neither too strong nor too weak by certain standards. In this paper, it is argued that (...) various forms of naturalistic dualism, of an emergentist character, are consistent with the strongest physical causal closure principles that can plausibly be advocated.

Os minerais possuem uma influência direta em diversos processos fisiológicos no organismo animal e, mesmo com tamanha importância, por vezes são negligenciados pelos produtores para seu fornecimento para os animais. Este estudo teve como objetivo avaliar o desempenho reprodutivo de rebanhos de bovinos, caprinos e ovinos em 8 propriedades rurais nas cidades de Sanharó, Pesqueira, Arcoverde, Belo Jardim e São Bento do Una através da adição de suplemento mineral e mistura múltipla aos animais de forma a atender suas necessidades básicas (...) para mantença e reprodução. Foram avaliados os desempenhos de 4 touros e 25 vacas, 3 bodes e 50 cabras e 4 carneiros e 48 ovelhas em diferentes propriedades, avaliando como a adição de um suplemento mineral específico da espécie impacta de forma positiva nos índices reprodutivos avaliados que foram taxa de cio, taxa de serviço, taxa de concepção, taxa de fertilidade, taxa de prenhez, taxa de perdas gestacionais, taxa de natalidade e taxa de mortalidade. O experimento teve duração de 2 anos e pôde-se avaliar cerca de 2 partos nas vacas e, mais ou menos, 3 partos em cabras e ovelhas. Os dados foram computados e avaliados estatisticamente no Excel para conferir se os índices reprodutivos melhoraram em função da adição de minerais na ração dos animais. Conferiu-se que houve diferença significativa entre todos os índices avaliados, ou seja, a adição de minerais na ração dos animais melhora a eficiência reprodutiva de machos e fêmeas de animais ruminantes, sendo de suma importância sua disponibilização de forma correta para alcançar bons índices reprodutivos na fazenda na busca pela obtenção de neonatos que poderão ser comercializados. -/- REFERÊNCIAS BIBLIOGRÁFICAS ASTRO, G.

The metaphysics of gender and race is a growing area of concern in contemporary analytic metaphysics, with many different views about the nature of gender and race being submitted and discussed. But what are these debates about? What questions are these accounts trying to answer? And is there real disagreement between advocates of differ- ent views about race or gender? If so, what are they really disagreeing about? In this paper I want to develop a view about what the debates (...) in the metaphysics of gender and race are about, namely, a version of metaphysical deflationism, according to which these debates are about how we actually use or should use the terms ‘gender’ and ‘race’ (and other related terms), where moral and political considerations play a central role. I will also argue that my version of the view can overcome some recent and powerful objections to metaphysical deflationism of- fered by Elizabeth Barnes (2014, 2017). (shrink)

Context: The problems that are most in need of interdisciplinary collaboration are “wicked problems,” such as food crises, climate change mitigation, and sustainable development, with many relevant aspects, disagreement on what the problem is, and contradicting solutions. Such complex problems both require and challenge interdisciplinarity. Problem: The conventional methods of interdisciplinary research fall short in the case of wicked problems because they remain first-order science. Our aim is to present workable methods and research designs for doing second-order science in domains (...) where there are many different scientific knowledges on any complex problem. Method: We synthesize and elaborate a framework for second-order science in interdisciplinary research based on a number of earlier publications, experiences from large interdisciplinary research projects, and a perspectivist theory of science. Results: The second-order polyocular framework for interdisciplinary research is characterized by five principles. Second-order science of interdisciplinary research must: 1. draw on the observations of first-order perspectives, 2. address a shared dynamical object, 3. establish a shared problem, 4. rely on first-order perspectives to see themselves as perspectives, and 5. be based on other rules than first-order research. Implications: The perspectivist insights of second-order science provide a new way of understanding interdisciplinary research that leads to new polyocular methods and research designs. It also points to more reflexive ways of dealing with scientific expertise in democratic processes. The main challenge is that this is a paradigmatic shift, which demands that the involved disciplines, at least to some degree, subscribe to a perspectivist view. Constructivist content: Our perspectivist approach to science is based on the second-order cybernetics and systems theories of von Foerster, Maruyama, Maturana & Varela, and Luhmann, coupled with embodied theories of cognition and semiotics as a general theory of meaning from von Uexküll and Peirce.
