Perception of time is susceptible to distortions; among other factors, it has been suggested that the perceived duration of a stimulus is affected by the observer’s expectations. It has been hypothesized that the duration of an oddball stimulus is overestimated because it is unexpected, whereas repeated stimuli have a shorter perceived duration because they are expected. However, recent findings suggest instead that fulfilled expectations about a stimulus elicit an increase in perceived duration, and that the oddball effect occurs because the (...) oddball is a target stimulus, not because it is unexpected. Therefore, it has been suggested that top-down attention is sometimes sufficient to explain this effect, and sometimes only necessary, with an additional contribution from saliency. However, how the expectedness of a target stimulus and its salient features affect its perceived duration is still an open question. In the present study, participants’ expectations about and the saliency of target stimuli were orthogonally manipulated with stimuli presented on a short (Experiment 1) or long (Experiment 2) temporal scale. Four repetitive standard stimuli preceded each target stimulus in a task in which participants judged whether the target was longer or shorter in duration than the standards. Engagement of top-down attention to target stimuli increased their perceived duration to the same extent irrespective of their expectedness. A small but significant additional contribution to this effect from the saliency of target stimuli was dependent on the temporal scale of stimulus presentation. In Experiment 1, saliency only significantly increased perceived duration in the case of expected target stimuli. In contrast, in Experiment 2, saliency exerted a significant effect on the overestimation elicited by unexpected target stimuli, but the contribution of this variable was eliminated in the case of expected target stimuli. These findings point to top-down attention as the primary cognitive mechanism underlying the perceptual extraction and processing of task-relevant information, which may be strongly correlated with perceived duration. Furthermore, the scalar properties of timing were observed, favoring the pacemaker-accumulator model of timing as the underlying timing mechanism. (shrink)

Given the conceptual gap in the global justice debate today (where most of the talk is about the duties of the rich, but little is said about what the poor may do for themselves), in this article I reintroduce the idea of a right of necessity. I first delineate a normative framework for such a right, inspired by these historical accounts. I then offer a contemporary case where the exercise of the right of necessity would be morally legitimate according to (...) that framework – even though illegal and probably condemned by the standard moral norms. The case is that of a small group of Paraguayan campesinos (small farmers) suffering from the effects of a severe drought. In the third part, I introduce the concept of noncivil disobedience: I call an act of noncivil disobedience a conscientious, public, illegal and forcible act whose performance, while not necessarily intended directly as a means to bring about social and/or political change, may help to trigger these changes indirectly. In the fourth part, I suggest that certain instances where the right of necessity is overtly exercised – as in the case of the famine-struck Paraguayan campesinos – may also be interpreted in terms of noncivil disobedience, insofar as they serve a double function: as a means of satisfying immediate need, and as a marker of discontent in a society where the equal rights of individuals are a nominal ideal which remains unfulfilled in practice. I then address two objections that may be raised against resurrecting the idea of a right of necessity and identifying it in certain instances with noncivil disobedience. I conclude by suggesting that, at the point of convergence between the two, a basic right like the right of necessity recovers its value as an active, (rather than passive) entitlement of its holders, while the use of force enters the picture as a legitimate means that – at least under certain circumstances – may be resorted to within the limits of civil society.

From the end of the twelfth century until the middle of the eighteenth century, the concept of a right of necessity –i.e. the moral prerogative of an agent, given certain conditions, to use or take someone else’s property in order to get out of his plight– was common among moral and political philosophers, who took it to be a valid exception to the standard moral and legal rules. In this essay, I analyze Samuel Pufendorf’s account of such a right, founded (...) on the basic instinct of self-preservation and on the notion that, in civil society, we have certain minimal duties of humanity towards each other. I review Pufendorf’s secularized account of natural law, his conception of the civil state, and the function of private property. I then turn to his criticism of Grotius’s understanding of the right of necessity as a retreat to the pre-civil right of common use, and defend his account against some recent criticisms. Finally, I examine the conditions deemed necessary and jointly sufficient for this right to be claimable, and conclude by pointing to the main strengths of this account. Keywords: Samuel Pufendorf, Hugo Grotius, right of necessity, duty of humanity, private property. (shrink)

By giving sympathy a central role, Adam Smith’s Theory of Moral Sentiments (1759) can be regarded as one of the ‘enlightened’ moral theories of the Enlightenment, insofar as it widened the scope of moral consideration beyond the traditionally restricted boundary of human beings. This, although the author himself does not seem to have been aware of this fact. In this paper, I want to focus on two aspects which I think lead to this conclusion. First, by making sentience the requisite (...) to be taken into moral consideration, nonhuman animals in Smith’s moral theory can count as moral patients towards whom we should exercise the virtue of beneficence (if not justice). Secondly, Smith’s idea of morality as working in concentric circles –generating more stringent duties towards those closer to us– could explain and perhaps also justify our caring for some nonhuman animals, especially pets.

Narrowly understood, veganism is the practice of excluding all animal products from one’s diet, with the exception of human milk. More broadly, veganism is not only a food ethics, but it encompasses all other areas of life. As defined by the Vegan Society when it became an established charity in the UK in 1979, veganism is best understood as “a philosophy and way of living which seeks to exclude – as far as is possible and practicable – all forms of (...) exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of humans, animals and the environment”. There are two main moral justifications for veganism, both of which rely on a common assumption: that sentience, i.e., the capacity to feel pleasure and pain, is the necessary and sufficient trait to be morally considerable. In what follows, I present these two justifications and a third one which, although less popular, captures some core intuitions among vegans. I then present a challenge faced by veganism and two arguments that reject it as discriminatory, and briefly conclude. (shrink)

The aim of this paper lies in characterizing the explanations and models used in the field of evolutionary developmental biology throughout its history. While manipulative experiments in controlled conditions have been useful to set the bases of the discipline and are still routinely performed, this approach supposes a tension between the reliability and the representativity of the conclusions. Given the recent changes in the understanding of evolutionary phenomena, different authors currently emphasize the need of avoiding excessive simplifications in experimental approaches, (...) incorporating the complexity of the analyzed systems as a relevant trait in the study of biological diversity. On the other hand, the fragile and contingent nature of evolutionary processes and the impossibility of intervening some of these phenomena underscore the importance of non-manipulative models that allow the elucidation of how-possibly mechanisms. We argue that a pluralism characterized by the integration of different kinds of explanations, models and metaphors used in evo-devo allows to exploit their respective advantages, favours interdisciplinarity and can contribute to form a representative description of evolutionary processes without relinquishing the local and detailed study of actual mechanisms.

At the basis of modern natural law theories, the concept of the suum, or what belongs to the person (in Latin, his, her, its, their own), has received little scholarly attention despite its importance both in explaining and justifying not only the genealogy of property, but also that of morality and war.1 In this paper I examine Hugo Grotius's what it is, what things it includes, what rights it gives rise to and how it is extended in the transition from (...) the state of nature to civil society. I then briefly point out how bringing this concept back to the fore could help to illuminate the current discussion on the foundations of basic human rights, and to evaluate cases where these seem to clash with property rights.

According to the brain drain argument, there are good reasons for states to limit the exit of their skilled workers (more specifically, healthcare workers), because of the negative impacts this type of migration has for other members of the community from which they migrate. Some theorists criticise this argument as illiberal, while others support it and ground a duty to stay of the skilled workers on rather vague concepts like patriotic virtue, or the legitimate expectations of their state and co-citizens. (...) In this article, on the contrary, we suggest that the liberal conception of states’ legitimate political authority demands, and not just permits, that developing states from which migration of skilled workers occurs set up contractual mechanisms. These mechanisms will ensure that state-funded training in the health sector is provided against a commitment on the part of future professionals to reciprocate with their services for the benefits obtained. If one of the conditions for the state to maintain legitimate political authority is to provide basic services such as healthcare to its subjects (while respecting at the same time their autonomy and freedom), then this is what developing states affected by the brain drain ought to do. What we call the authority-based approach to the brain drain also helps to clarify the obligations that other states have not to interfere with these contractual mechanisms when they exist, and not to profit from their absence. Inspired by FIFA’s legal instruments of training compensation and solidarity mechanism for the transfer of players, we conclude by suggesting a plausible global policy to complement this authority-based approach.

Our concern is with the ethical issues related to girlhood and bodily integrity—the right to be free from physical harm and harassment and to experience freedom and security in relation to the body. We defend agency, positive self-relations, and health as basic elements of bodily integrity and we advocate that this normative concept be used as a conceptual tool for the protection of the rights of girls. We assume the capability approach developed by Martha Nussbaum as an ethical framework that (...) enables us to evaluate girls’ well-being and well-becoming in relation to the potential, and often subtle, threats they face. The capability approach can be understood as a theory of justice, and, therefore, as an ethical and political approach. An enriched concept of bodily integrity can help in the design of better policies to address gender biases against girls because it could contribute to seeing them as active agents and valid participants.

he territorial impacts of climate change will affect millions. This will happen not only as a direct consequence of climate change, but also because of policies for mitigating it—for example, through the installation of large wind and solar farms, the conservation of land in its role as carbon sink, and the extraction of materials needed for renewable energy technologies. In this article, we offer an overview of the justice-related issues that these impacts create. The literature on climate justice and territory (...) is vast and spans a range of disciplines, so we limit our discussion to a specific understanding of territory and a specific understanding of injustice that arises from its loss. We understand territory as a normative concept that describes a place under some agent's jurisdiction, where the agent is a politically organized collective and where the jurisdictional rights over that place secure a relevant degree of self-determination for that collective. Accordingly, we consider that the main injustice connected to the loss of territory due to climate change is the loss or undermining of the ability to exercise the collective right to self-determination, which requires some control over the place. This can happen if a territorial agent literally loses the ground where to stand as a direct effect of climate change, raising issues of justice in relocation; or if their place changes due to mitigation policies, affecting their use and understanding of territory, raising issues of justice in energy transition. In concluding, we point to topics for future research. (shrink)

Given certain standard assumptions-that particular sentences are meaningful, for example, and do genuinely self-attribute their own falsity-the paradoxes appear to show intriguing patterns of generally unstable semantic behavior. In what follows we want to concentrate on those patterns themselves: the pattern of the Liar, for example, which if assumed either true or false appears to oscillate endlessly between truth and falsehood.

This paper argues that the exercise of the imagination requires us 1) to attempt to describe features of a certain practice that appear, at first blush, natural and obvious; 2) to understand that that which appears natural and obvious could be otherwise; and 3) to be open to the introduction of changes to that which appears natural and obvious. Imagination, in this sense, is quite different to creativity. The latter works on the basis of the introduction of variations to settled (...) phenomena. This exercise of creativity is important, but ultimately, it contributes principally to the stability and identity of a community and reinforces its most firmly established features. Imagination, on the other hand, is more difficult, for it strikes at the very heart of that which is settled. Changes to that which is settled may not only be resisted, but may also be violently opposed. And yet, it is precisely the very ability and willingness to be open to such changes that may be of the most ethical and political significance. These differences between creativity and imagination are illustrated in the context of the practice of philosophy. (shrink)

The Plant Ontology (PO) is a community resource consisting of standardized terms, definitions, and logical relations describing plant structures and development stages, augmented by a large database of annotations from genomic and phenomic studies. This paper describes the structure of the ontology and the design principles we used in constructing PO terms for plant development stages. It also provides details of the methodology and rationale behind our revision and expansion of the PO to cover development stages for all plants, particularly (...) the land plants (bryophytes through angiosperms). As a case study to illustrate the general approach, we examine variation in gene expression across embryo development stages in Arabidopsis and maize, demonstrating how the PO can be used to compare patterns of expression across stages and in developmentally different species. Although many genes appear to be active throughout embryo development, we identified a small set of uniquely expressed genes for each stage of embryo development and also between the two species. Evaluating the different sets of genes expressed during embryo development in Arabidopsis or maize may inform future studies of the divergent developmental pathways observed in monocotyledonous versus dicotyledonous species. The PO and its annotation databasemake plant data for any species more discoverable and accessible through common formats, thus providing support for applications in plant pathology, image analysis, and comparative development and evolution.

The Ontology for Biomedical Investigations (OBI) is an ontology that provides terms with precisely defined meanings to describe all aspects of how investigations in the biological and medical domains are conducted. OBI re-uses ontologies that provide a representation of biomedical knowledge from the Open Biological and Biomedical Ontologies (OBO) project and adds the ability to describe how this knowledge was derived. We here describe the state of OBI and several applications that are using it, such as adding semantic expressivity to (...) existing databases, building data entry forms, and enabling interoperability between knowledge resources. OBI covers all phases of the investigation process, such as planning, execution and reporting. It represents information and material entities that participate in these processes, as well as roles and functions. Prior to OBI, it was not possible to use a single internally consistent resource that could be applied to multiple types of experiments for these applications. OBI has made this possible by creating terms for entities involved in biological and medical investigations and by importing parts of other biomedical ontologies such as GO, Chemical Entities of Biological Interest (ChEBI) and Phenotype Attribute and Trait Ontology (PATO) without altering their meaning. OBI is being used in a wide range of projects covering genomics, multi-omics, immunology, and catalogs of services. OBI has also spawned other ontologies (Information Artifact Ontology) and methods for importing parts of ontologies (Minimum information to reference an external ontology term (MIREOT)). The OBI project is an open cross-disciplinary collaborative effort, encompassing multiple research communities from around the globe. To date, OBI has created 2366 classes and 40 relations along with textual and formal definitions. The OBI Consortium maintains a web resource providing details on the people, policies, and issues being addressed in association with OBI. (shrink)

El acceso a la justicia como derecho, y el diseño e implementación de políticas públicas que lo tornen operante, exige un abordaje formativo crítico que se inscriba en la línea de una triple articulación: filosófica, jurídica y política. Enmarcada en dicha pretensión, la propuesta del curso “Agencias judiciales, políticas públicas y acceso a la justicia” tiene por objeto: a)Promover la reflexión sobre el acceso a la justicia como núcleo problemático de nuestra contemporaneidad social y jurídica. b)Reinscribir dicha reflexión crítica en (...) las filiaciones iusfilosóficas que la posibilitan e impulsan. c)Conceptualizar el acceso a la justicia como desafío medular de políticas de inclusión social.d)Identificar las complejidades que se derivan del carácter críptico y técnico que reviste el derecho moderno y el lenguaje jurídico que lo constituye, circunstancia que dificulta su accesibilidad y difusión. e)Efectuar aportes formativos que sirvan de base para la elaboración de políticas de acceso a la justicia que posibiliten la desarticulación de esta opacidad y formalización del lenguaje jurídico. f)Advertir el carácter performativo que porta el derecho como práctica social discursiva no solo como esfera de producción normativa sino también de construcción de las representaciones sociales que se disputan en la escena pública. g)Comprender el rol fundamental que poseen las agencias judiciales como instancias de promoción y desarrollo de políticas públicas en materia de acceso a la justicia. h)Esbozar los desafíos de dichas agencias judiciales para la profundización del acceso a la justicia como derecho vinculado a problemáticas específicas tales como la vulnerabilidad social y la diversidad cultural y lingüística.

The phrase ‘person‐centred care’ (PCC) reminds us that the fundamental philosophical goal of caring for people is to uphold or promote their personhood. However, such an idea has translated into promoting individualist notions of autonomy, empowerment and personal responsibility in the context of consumerism and neoliberalism, which is problematic both conceptually and practically. From a conceptual standpoint, it ignores the fact that humans are social, historical and biographical beings, and instead assumes an essentialist or idealized concept of personhood in which (...) a person is viewed as an individual static object. From a practical standpoint, the application of such a concept of personhood can lead to neglect of a person's fundamental care needs and exacerbate the problems of social inequity, in particular for older people and people with dementia. Therefore, we argue that our understanding of PCC must instead be based on a dynamic concept of personhood that integrates the relevant social, relational, temporal and biographical dimensions. We propose that the correct concept of personhood in PCC is one in which persons are understood as socially embedded, relational and temporally extended subjects rather than merely individual, autonomous, asocial and atemporal objects. We then present a reconceptualization of the fundamental philosophical goal of PCC as promoting selfhood rather than personhood. Such a reconceptualization avoids the problems that beset the concept of personhood and its application in PCC, while also providing a philosophical foundation for the growing body of empirical literature that emphasizes the psychosocial, relational, subjective and biographical dimensions of PCC.

Intuitively, there is a difference between knowledge and mere belief. Contemporary philosophical work on the nature of this difference has focused on scenarios known as “Gettier cases.” Designed as counterexamples to the classical theory that knowledge is justified true belief, these cases feature agents who arrive at true beliefs in ways which seem reasonable or justified, while nevertheless seeming to lack knowledge. Prior empirical investigation of these cases has raised questions about whether lay people generally share philosophers’ intuitions about these (...) cases, or whether lay intuitions vary depending on individual factors (e.g. ethnicity) or factors related to specific types of Gettier cases (e.g. cases that include apparent evidence). We report an experiment on lay attributions of knowledge and justification for a wide range of Gettier Cases and for a related class of controversial cases known as Skeptical Pressure cases, which are also thought by philosophers to elicit intuitive denials of knowledge. Although participants rated true beliefs in Gettier and Skeptical Pressure cases as being justified, they were significantly less likely to attribute knowledge for these cases than for matched true belief cases. This pattern of response was consistent across different variations of Gettier cases and did not vary by ethnicity or gender, although attributions of justification were found to be positively related to measures of empathy. These findings therefore suggest that across demographic groups, laypeople share similar epistemic concepts with philosophers, recognizing a difference between knowledge and justified true belief.

The study of biodiversity spans many disciplines and includes data pertaining to species distributions and abundances, genetic sequences, trait measurements, and ecological niches, complemented by information on collection and measurement protocols. A review of the current landscape of metadata standards and ontologies in biodiversity science suggests that existing standards such as the Darwin Core terminology are inadequate for describing biodiversity data in a semantically meaningful and computationally useful way. Existing ontologies, such as the Gene Ontology and others in the Open (...) Biological and Biomedical Ontologies (OBO) Foundry library, provide a semantic structure but lack many of the necessary terms to describe biodiversity data in all its dimensions. In this paper, we describe the motivation for and ongoing development of a new Biological Collections Ontology, the Environment Ontology, and the Population and Community Ontology. These ontologies share the aim of improving data aggregation and integration across the biodiversity domain and can be used to describe physical samples and sampling processes (for example, collection, extraction, and preservation techniques), as well as biodiversity observations that involve no physical sampling. Together they encompass studies of: 1) individual organisms, including voucher specimens from ecological studies and museum specimens, 2) bulk or environmental samples (e.g., gut contents, soil, water) that include DNA, other molecules, and potentially many organisms, especially microbes, and 3) survey-based ecological observations. We discuss how these ontologies can be applied to biodiversity use cases that span genetic, organismal, and ecosystem levels of organization. We argue that if adopted as a standard and rigorously applied and enriched by the biodiversity community, these ontologies would significantly reduce barriers to data discovery, integration, and exchange among biodiversity resources and researchers.

Do laypeople and philosophers differ in their attributions of knowledge? Starmans and Friedman maintain that laypeople differ from philosophers in taking ‘authentic evidence’ Gettier cases to be cases of knowledge. Their reply helpfully clarifies the distinction between ‘authentic evidence’ and ‘apparent evidence’. Using their sharpened presentation of this distinction, we contend that the argument of our original paper still stands.

The discipline of knowledge translation (KT) emerged as a way of systematically understanding and addressing the challenges of applying health and medical research in practice. In light of ongoing and emerging critique of KT from the medical humanities and social sciences disciplines, KT researchers have become increasingly aware of the complexity of the translational process, particularly the significance of culture, tradition and values in how scientific evidence is understood and received, and thus increasingly receptive to pluralistic notions of knowledge. Hence, (...) there is now an emerging view of KT as a highly complex, dynamic, and integrated sociological phenomenon, which neither assumes nor creates knowledge hierarchies and neither prescribes nor privileges scientific evidence. Such a view, however, does not guarantee that scientific evidence will be applied in practice and thus poses a significant dilemma for KT regarding its status as a scientific and practice-oriented discipline, particularly within the current sociopolitical climate. Therefore, in response to the ongoing and emerging critique of KT, we argue that KT must provide scope for relevant scientific evidence to occupy an appropriate position of epistemic primacy in public discourse. Such a view is not intended to uphold the privileged status of science nor affirm the “scientific logos” per se. It is proffered as a counterbalance to powerful social, cultural, political and market forces that are able to challenge scientific evidence and promote disinformation to the detriment of democratic outcomes and the public good.

Justice for children and during childhood and the particular political, social and moral status of children has long been a neglected issue in ethics, and in social and political philosophy. The application of general, adult-oriented theories of justice to children can be regarded as particularly problematic. Philosophers have only recently begun to explore what it means to consider children as equals, what goods are especially valuable to them, and what are the obligations of justice different agents have toward children. In (...) addition, while philosophers have extensively written about global poverty and inequality, the issue of disadvantages during childhood, especially child poverty, has only been superficially addressed. This also applies to the Capability Approach (CA) as a normative theory. Although the socio-scientific and economic literature on how to conceptualize capabilities and functionings of children and how to measure them in the context of poverty and wellbeing is steadily growing, the normative aspects of these issues are still under-theorized. The CA offers a unique framework to engage with both the topic of justice for children and questions concerning what justice implies and demands with regard to children living and growing up in disadvantaged circumstances. Furthermore, justice and disadvantage during childhood is a compellingly interdisciplinary topic that invites the combination of ethical and philosophical reasoning together with socio-scientific theories and empirical knowledge. In this special issue of Ethical Perspectives we bring together theoretical and empirically informed discussions that explore the CA in relation to children and the many disadvantages they can face in their lives.

'People travelled for numerous reasons,' so J.W. Drijvers submits at the beginning of his piece on travel and pilgrimage literature. Be it ‘commerce, government affairs, religion, education, military business or migration,’ people ‘made use of the elaborate system of roads and modes of transport such as wagons, horses and boats’ to traverse the far-reaching stretches of the Roman Empire. And for 4th century Christians in particular, participating in religious festivals as well as interaction with holy sites, sacred artifacts and clergymen (...) had become greater a reason to travel still. Motivation to travel, in other words, was aplenty. But what exactly allowed for Christian religious travel in the 4th century AD to develop as quickly as it did? (shrink)

This article offers two arguments for the conclusion that we should refuse on moral grounds to establish a human presence on the surface of Mars. The first argument appeals to a principle constraining the use of invasive or destructive techniques of scientific investigation. The second appeals to a principle governing appropriate human behavior in wilderness. These arguments are prefaced by two preliminary sections. The first preliminary section argues that authors working in space ethics have good reason to shift their focus (...) away from theory-based arguments in favor of arguments that develop in terms of pretheoretic beliefs. The second argues that of the popular justifications for sending humans to Mars only appeals to scientific curiosity can survive reflective scrutiny. (shrink)

As space travel and intentions to colonise other planets are becoming the norm in public debate and scholarship, we must also confront the technical and survival challenges that emerge from these hostile environments. This paper aims to evaluate the various arguments proposed to meet the challenges of human space travel and extraterrestrial planetary colonisation. In particular, two primary solutions have been present in the literature as the most straightforward solutions to the rigours of extraterrestrial survival and flourishing: (1) geoengineering, where (...) the environment is modified to become hospitable to its inhabitants, and (2) human (bio)enhancement where the genetic heritage of humans is modified to make them more resilient to the difficulties they may encounter as well as to permit them to thrive in non-terrestrial environments. Both positions have strong arguments supporting them but also severe philosophical and practical drawbacks when exposed to different circumstances. This paper aims to show that a principled stance where one position is accepted wholesale necessarily comes at the opportunity cost of the other where the other might be better suited, practically and morally. This paper concludes that case-by-case evaluations of the solutions to space travel and extraterrestrial colonisation are necessary to ensure moral congruency and the survival and flourishing of astronauts now and into the future.

The oil industry has played a significant role in the economy of modern Iran and Malaysia, especially as a source of transnational exchange and as a substantial factor in industrial and urban development. During the previous century, the arrival of oil companies in the Persian Gulf brought many changes to the physical built environment and accelerated the urbanization process in the port cities. Similarly, the development of the national oil industry had a considerable impact on post-independence Malaysia, affecting balance sheets, (...) the environment, and society. Oil significantly changed Malaysia’s position in the global economy and transformed a predominantly agricultural country into a significant producer of petroleum and natural gas. This paper implements the analytical, historical, and comparative perspectives. Specifically, it focuses on the legacy of oil cities in the Persian Gulf and the South China Sea as the birthplaces of the oil industry in two regions. In both countries, geopolitical importance and oil’s cultural, social, and historical narratives have the potential to represent national unity, political memory, and collective identity. In proposing this grounding, the paper seeks to approach the oil heritage as a particular form of industrial heritage. This research analyses the future of energy heritage, existing Covid-related challenges, and political tensions and examines the various impacts, transitions, and capacities associated with the current international relations, post-pandemic urban developments, and the post-oil future to pave the way for these developing areas of industrial heritage and oil heritage in Iran and Malaysia.

No matter how far we soar into the stars, (...) our psychologies for future generations will be forever tethered to the totality of our surroundings. By shaping our environment toward survival and welfare during the voyage to Mars and in a Martian colony, we indirectly shape our psyches and prepare them for a mission of unprecedented alienation and duration. Once on Mars, human factors such as leadership structure, social organization and code of conduct, group size, gender balance, developmental cycle, mobility, length of stay and the ecological settings and type and manner of subsistence, will create a novel Martian culture. The degree that settlers are severed from the Earth will affect how radically foreign this culture will be when compared with cultures on Earth. (shrink)

In our everyday experience, life, environment, and nature are connected and we tend to confuse the value we assign to them. One way around this issue is to analyze our intuitions on the terraformation of other planets such as Mars. In this way, we are forced to consider whether the original abiotic nature has a value of some kind regardless of its capacity to support ecosystems and life, what kind of value this might be, and what weight it might have (...) when compared with other values. In this contribution, I will draw a map of the possible answers to these questions by analyzing the different perspectives brought forth by some of the main characters in K. S. Robinson's The Mars Trilogy. In this way, it will be possible to observe that, while on Earth instrumental and non-instrumental kinds of environmental value generally concur and support each other, in an abiotic landscape, such as that offered (we assume) by Mars, they may conflict.

Terraforming is a process of planetary engineering by which the extant environment of a planetary body is transformed into an environment capable of supporting human inhabitants. The question I would like to consider in this paper is whether there is any reason to believe that the terraforming of another planet—for instance, the terraforming of Mars—is morally problematic. Topics related to the human exploration of space are not often discussed in philosophical circles. Nevertheless, there exists a growing body of philosophical literature (...) dedicated to sorting out the moral implications of the use of resources from (and in) space. Most of this literature is produced as environmental philosophy. Questions of .. (shrink)

A critical exposition of plans to colonize other planets , especially Mars, and their costs. The final chapter links with issues about the value and future of human life. See the extended summary uploaded to this site.

If we had the ability to terraform Mars, would it be morally permissible to do it? This article surveys three preservationist arguments for the conclusion that we should not terraform Mars and three interventionist arguments that we should. The preservationist arguments appeal to a duty to conserve objects of special scientific value, a duty to preserve special wilderness areas, and a duty not to display vices characteristic of past colonial endeavors on Earth. The interventionist arguments appeal to a duty to (...) fulfill our pioneering nature, a duty to extend the lifespan of our species, and a duty to restore the ecosystems Mars may once have housed. The preservationist arguments are stronger than the interventionist arguments; terraforming Mars is probably morally wrong. (shrink)

We are on Mars again – the favourite laboratory for philosophical experiments. Our host colleagues introduce us to some Martian stuff referred to as “T”, and ask us to help them to identify T on other possible worlds. Or, technically speaking, we are asked to determine the intension of “T”, i.e., what the term designates with respect to different possible worlds. Following a short series of experiments on the planet, we conclude that the intension of “T” depends upon three factors: (...) (1) The semantic rule linked with the term, i.e., the way in which the term is designed to pick out its referent with respect to different possible worlds (e.g., as a definite description, or as a proper name, or as an actualised description etc.); (2) The properties of the referent of “T” in the actual world; and, (3) What we shall call ‘the metaphysical background of the universe’, i.e., what counts as a thing vs. what counts as a property of things (e.g., whether the universe is such that it contains material objects that merely happen to have their manifest properties, or whether the universe primarily contains manifest objects that merely happen to have their material constitution). As our experiments show, changing the values of any of these variables will result in a change in the reference of the term with respect to different possible worlds, viz., it will result in a change in the intension of the term. We then demonstrate how the three variables are interrelated, and specify how exactly they combine to produce a particular intension of a term. We conclude with a general “formula” that determines what will deserve to be called “T” relative to the different values of the above variables, i.e., we come up with a calculator of intensions. Finally, we also draw some morals about rigidity. (shrink)

Interdisciplinary dialogue acts as a symbiosis for all the areas that participate and imply enormous projections for both art and science. This paper explores the potential of an interdisciplinary dialogue between Biology and Performance using as a case study the Performance Analfabeta created by the artist Paulina Bronfman. The work was shaped in the context of The Third Conference of the Nucleus of Artistic Research (NIA) of In/Inter/Disciplinary Laboratories hosted by the Faculty of Art of The Pontificia University of Chile (...) (LAB IID). The Lab was led by Chilean biologist Alejandra Zuñiga- Feest and the Brazilian artist Adriana Parente La Selva. This work aims to explore the questions: what does it mean, from the point of view of the arts and sciences, to develop an interdisciplinary laboratory? How is this done? This paper problematizes the creative process of collaboration between sciences and performance as well as the potential impact and link with society that this multidisciplinary dialogue can have.

In this paper I defend anti-realism about race and a new theory of racialization. I argue that there are no races, only racialized groups. Many social constructionists about race have adopted racial formation theory to explain how ‘races’ are formed. However, anti-realists about race cannot adopt racial formation theory, because it assumes the reality of race. I introduce interactive constructionism about racialized groups as a theory of racialization for anti-realists about race. Interactive constructionism moves the discussion away from the dichotomous (...) (social vs. biological) metaphysics that has marred this debate, and posits that racialized groups are the joint products of a broad range of non-racial factors, which interact. (shrink)

Some authors argue that we have a moral obligation to leave Mars the way it is, even if it does not harbour any life. This claim is usually based on an assumption that Mars has intrinsic value. The problem with this concept is that different authors use it differently. In this chapter, I investigate different ways in which an uninhabited Mars is said to have intrinsic value. First, I investigate whether the planet can have moral standing. I find that this (...) is not a plausible assumption. I then investigate different combinations of objective value and end value. I find that there is no way we can know whether an uninhabited Mars has objective end value and even if it does, this does not seem to imply any moral obligations on us. I then investigate whether an uninhabited Mars can have subjective end value. I conclude that this is very plausible. I also investigate whether an uninhabited Mars can have objective instrumental value in relation to some other, non-Mars related end value. I find also this very plausible. It is also highly plausible, however, that spreading (human or other) life to a presently uninhabited Mars can also have subjective end value, as well as objective instrumental value. I mention shortly two ways of prioritising between these values: (1) The utilitarian method of counting the number of sentient beings who entertain each value and determining the strength of the values to them. (2) Finding a compromise that allows colonisation on parts of the planet while leaving other parts untouched. These methods should be seen as examples, not as an exhaustive list. Also, I do not take a definitive stand in favour of any of the two approaches, though it seems at least prima facie that the second approach may have a better chance of actually leading to a constructive result.

“Gettier cases” have played a major role in Anglo-American analytic epistemology over the past fifty years. Philosophers have grouped a bewildering array of examples under the heading “Gettier case.” Philosophers claim that these cases are obvious counterexamples to the “traditional” analysis of knowledge as justified true belief, and they treat correctly classifying the cases as a criterion for judging proposed theories of knowledge. Cognitive scientists recently began testing whether philosophers are right about these cases. It turns out that philosophers were (...) partly right and partly wrong. Some “Gettier cases” are obvious examples of ignorance, but others are obvious examples of knowledge. It also turns out that much research in this area of philosophy is marred by experimenter bias, invented historical claims, dysfunctional categorization of examples, and mischaracterization by philosophers of their own intuitive judgments about particular cases. Despite these shortcomings, lessons learned from studying “Gettier cases” are leading to important insights about knowledge and knowledge attributions, which are central components of social cognition.

In this paper, I undertake a conceptual analysis of ordinary usages of the concepts of “litter” and “pollution.” If “litter” or “pollution” applies to space debris in its various contexts, then in dealing with space debris as an ethical concern, we may more neatly apply arguments for the wrongness of litter and pollution to these new contexts. After engaging in a conceptual analysis of “litter” and “pollution,” I consider whether these concepts apply to space debris, examining three contexts: (1) surface (...) debris on Moon and Mars, (2) intentionally crashing objects into gas giants, ice giants, and stars, and (3) the pressing issue of orbital space debris. I conclude by finding that neither “litter” nor “pollution” cleanly applies to any of these three contexts. (shrink)
