This study investigated whether 6 weeks of basketball combined with mathematics once a week in physical education lessons could improve children's motivation for mathematics. Seven hundred fifty-seven children were randomly selected to have either basketball combined with mathematics once a week or to have basketball sessions without mathematics. Children in BM and CON motivation for classroom-based mathematics were measured using the Academic Self-Regulation Questionnaire before and after the intervention. Among the BM, levels of intrinsic motivation, feelings of competence, and autonomy (...) were measured using the Post-Experimental Intrinsic Motivation Inventory questionnaire acutely after a basketball session combined with mathematics and immediately after a session of classroom-based mathematics. BM had significantly higher acute levels of perceived autonomy, competencies, and intrinsic motivation during basketball sessions combined with mathematics compared to when having classroom-based mathematics. A significant decrease in the mean for intrinsic motivation was observed from T0 to T1 for CON, but not for BM. BM had a more positive development in intrinsic motivation compared to CON from T0 to T1, meaning that BM had a positive influence on children's intrinsic motivation for classroom-based mathematics. This study indicates that basketball combined with mathematics is an intrinsically motivating way to practice mathematics, which also has a positive influence on children's general intrinsic motivation for mathematics in the classroom.

In this paper we investigate how inference to the best explanation (IBE) works in engineering science, focussing on the context of malfunction explanation. While IBE has gotten a lot of attention in the philosophy of science literature, few, if any, philosophical work has focussed on IBE in engineering science practice. We first show that IBE in engineering science has a similar structure as IBE in other scientific domains in the sense that in both settings IBE hinges on the weighing of (...) explanatory virtues. We then proceed to show that, due to the intimate connection between explanation and redesign in engineering science, there is a further engineering domain-specific virtue in terms of which engineering malfunction explanations are evaluated, viz. the virtue of redesign utility. This virtue entails that the explanatory information offered by a malfunction explanation should be instrumental in predicting counterfactual dependencies in redesigned systems. We illustrate and elaborate these points in terms of a number of engineering examples, focussing in particular on the 2009 crash of Air France Flight 447. Our extension of analyses of IBE and explanation to engineering science practice offers new insights by identifying a new explanatory virtue in malfunction explanation: redesign utility. (shrink)

Laguna Lake, the largest lake in the Philippines, supplies Manila's dense urban region with fish and water while operating as a sink for its stormflows and wastes. Transforming the lake to deliver these multiple urban ecological functions, however, has generated resource conflicts and contradictions that unfold unevenly across space. In Urban Ecologies on the Edge, Kristian Karlo Saguin tracks the politics of resource flows and unpacks the narratives of Laguna Lake as Manila's resource frontier. Provisioning the city and keeping (...) it safe from floods are both frontier-making processes that bring together contested socioecological imaginaries, practices, and relations. Combining fieldwork and historical accounts, Saguin demonstrates how people--powerful and marginalized--interact with the state and the environment to produce the unequal landscapes of urbanization at and beyond the city's edge.

It has become increasingly common for philosophers to distinguish between objective and subjective rightness, and there has been much discussion recently about what an adequate theory of subjective rightness looks like. In this article, I propose a new theory of subjective rightness. According to it, an action is subjectively right if and only if it minimizes expected objective wrongness. I explain this theory in detail and argue that it avoids many of the problems that other theories of subjective rightness face. (...) I end by responding to some objections. (shrink)

What is the best way of assessing the extent to which people are aware of a stimulus? Here, using a masked visual identification task, we compared three measures of subjective awareness: The Perceptual Awareness Scale , through which participants are asked to rate the clarity of their visual experience; confidence ratings , through which participants express their confidence in their identification decisions, and Post-decision wagering , in which participants place a monetary wager on their decisions. We conducted detailed explorations of (...) the relationships between awareness and identification performance, looking to determine which scale best correlates with performance, and whether we can detect performance in the absence of awareness and how the scales differ from each other in terms of revealing such unconscious processing. Based on these findings we discuss whether perceptual awareness should be considered graded or dichotomous. Results showed that PAS showed a much stronger performance-awareness correlation than either CR or PDW, particularly for low stimulus intensities. In general, all scales indicated above-chance performance when participants claimed not to have seen anything. However, such above-chance performance only showed when we also observed a correlation between awareness and performance. Thus PAS seems to be the most exhaustive measure of awareness, and we find support for above-chance performance in the absence of subjective awareness, but such unconscious knowledge only contributes to performance when we observe conscious knowledge as well. Similarities and differences between scales are discussed in the light of consciousness theories and response strategies. (shrink)

This paper outlines a procedure for assessing the quality of failure explanations in engineering failure analysis. The procedure structures the information contained in explanations such that it enables to find weak points, to compare competing explanations, and to provide redesign recommendations. These features make the procedure a good asset for critical reflection on some areas of the engineering practice of failure analysis and redesign. The procedure structures relevant information contained in an explanation by means of structural equations so as to (...) make the relations between key elements more salient. Once structured, the information is examined on its potential to track counterfactual dependencies by offering answers to relevant what-if-things-had-been-different questions. This criterion for explanatory goodness derives from the philosophy of science literature on scientific explanation. The procedure is illustrated by applying it to two case studies, one on Failure Analysis in Mechanical Engineering (a broken vehicle shaft) and one on Failure Analysis in Civil Engineering (a collapse in a convention center). The procedure offers failure analysts a practical tool for critical reflection on some areas of their practice while offering a deeper understanding of the workings of failure analysis (framing it as an explanatory practice). It, therefore, allows to improve certain aspects of the explanatory practices of failure analysis and redesign, but it also offers a theoretical perspective that can clarify important features of these practices. Given the programmatic nature of the procedure and its object (assessing and refining explanations), it extends work on the domain of computational argumentation. (shrink)

Despite a long history of researchers who combine phenomenology with qualitative or quantitative methods, there are only few examples of working with a phenomenological mixed method—a method where phenomenology informs both qualitative and quantitative data generation, analysis, and interpretation. Researchers have argued that in working with a phenomenological mixed method, there should be mutual constraint and enlightenment between the qualitative and quantitative methods for studying consciousness. In this article, we discuss what a framework for phenomenological mixed methods could look like (...) and we aim to provide guidance of how to work within such framework. We are inspired by resources coming from research in mixed methods and existing examples of phenomenological mixed-method research. We also present three cases of phenomenological mixed methods where we study complex social phenomena and discuss the process of how we conducted the studies. From both the research inspiration and our own studies, we depict the landscape of possibilities available for those interested in mixing phenomenology with qualitative and quantitative methods, as well as the challenges and common pitfalls that researchers face. To navigate in this landscape, we develop a three-fold structure, focusing on the phenomenological frame, the phenomenologically informed generation of qualitative and quantitative data, and the phenomenologically informed analysis and interpretation of data.

In this paper, I motivate and defend the distinction between an objective and a subjective moral sense of “ought.” I begin by looking at the standard way the distinction is motivated, namely by appealing to relatively simple cases where an agent does something she thinks is best, but her action has a tragic outcome. I argue that these cases fail to do the job—the intuitions they elicit can be explained without having to distinguish between different senses of “ought.” However, these (...) cases are on the right track—I argue that more sophisticated versions of the cases provide strong motivation for the distinction. I then discuss two important problems for the distinction: the “which ‘ought’ is more important?” problem, and the “annoying profusion of ‘oughts’” problem. I argue that each of these problems can be solved in several different ways. (shrink)

Background Research is fundamental to improving the quality of health care. The need for regulation of research is clear. However, the bureaucratic complexity of research governance has raised concerns that the regulatory mechanisms intended to protect participants now threaten to undermine or stifle the research enterprise, especially as this relates to sensitive topics and hard to reach groups. Discussion Much criticism of research governance has focused on long delays in obtaining ethical approvals, restrictions imposed on study conduct, and the inappropriateness (...) of evaluating qualitative studies within the methodological and risk assessment frameworks applied to biomedical and clinical research. Less attention has been given to the different epistemologies underlying biomedical and qualitative investigation. The bioethical framework underpinning current regulatory structures is fundamentally at odds with the practice of emergent, negotiated micro-ethics required in qualitative research. The complex and shifting nature of real world settings delivers unanticipated ethical issues and (occasionally) genuine dilemmas which go beyond easy or formulaic ‘procedural’ resolution. This is not to say that qualitative studies are ‘unethical’ but that their ethical nature can only be safeguarded through the practice of ‘micro-ethics’ based on the judgement and integrity of researchers in the field. Summary This paper considers the implications of contrasting ethical paradigms for the conduct of qualitative research and the value of ‘empirical ethics’ as a means of liberating qualitative (and other) research from an outmoded and unduly restrictive research governance framework based on abstract prinicipalism, divorced from real world contexts and values.

During recent decades various researchers from health and social sciences have been debating what it means for a person to be disabled. A rather overlooked approach has developed alongside this debate, primarily inspired by the philosophical tradition called phenomenology. This paper develops a phenomenological model of disability by arguing for a different methodological and conceptual framework from that used by the existing phenomenological approach. The existing approach is developed from the phenomenology of illness, but the paper illustrates how the case (...) of congenital disabilities, looking at the congenital disorder called cerebral palsy (CP), presents a fundamental problem for the approach. In order to understand such congenital cases as CP, the experience of disability is described as being gradually different from, rather than a disruption of, the experience of being abled, and it is argued that the experience of disability is complex and dynamically influenced by both intrinsic and extrinsic factors. Different experiential aspects of disability— pre-reflective, attuned and reflective aspects—are described, demonstrating that the experience of disability comes in different degrees. Overall, this paper contributes to the debates about disability by further describing the personal aspects and experience of persons living with disabilities. (shrink)

How may we change ourselves and our society so that animals are treated more justly? To answer this question, I turn to the account of moral change developed by the philosopher Iris Murdoch. The chief obstacle to becoming better, she believed, is an attachment to fantasy, from which we are liberated only through a loving attention directed at the reality of other beings. Building on this account, I argue that human supremacy is one such fantasy—that it acts as an impediment (...) to interspecies justice. I end with a meditation on love as liberatory practice.

In this dissertation, I develop and defend some of W. D. Ross’s moral views. Ross’s views, I argue, are often highly plausible, though it is also often the case that variations on (or modifications to) his views are needed in order to remain philosophically tenable. In my dissertation, I explain why these variations are necessary and what they should look like. In chapter 1, I discuss Ross’s theory of moral rightness in his most important work, The Right and the Good. (...) In chapters 2 and 3, I correct various misunderstandings about Ross’s position: I argue that he is no more a particularist about absolute duty than a utilitarian or a Kantian is, and on many definitions of “pluralism” present in the literature, he is not in fact a pluralist, as he is typically assumed to be. In chapter 4, I discuss several objections that Ross later comes to make to his own theory of rightness; I argue, however, that none of them are any good. In chapter 5, I argue against Ned Markosian’s recent claim that “Rossian Minimalism” is the best theory of rightness that makes use of the concept of a prima facie duty: Ross’s own theory (or, at least, a “world” version of it) is, I maintain, superior to Rossian Minimalism. In chapter 6, I address some objections to Ross’s theory suggested by Michael Stocker and Michael Slote and demonstrate that the best way of responding to them is by transforming Ross’s theory into a “dual-ranking” one. In chapter 7, I discuss Ross’s theory of the subjective sense of “right” (chapters 1-6 are primarily concerned with Ross’s theory of the objective sense of the term). I show that Ross’s theory is problematic, and I offer a better theory in its place. In chapter 8, I turn to Ross’s theory of moral goodness. I argue that his theory is more plausible than other theories suggested in the literature, but it suffers from the “nepotism problem.” I show that Ross’s solution to this problem is unsatisfactory and suggest a better way forward.

When consciousness is examined using subjective ratings, the extent to which processing is conscious or unconscious is often estimated by calculating task performance at the subjective threshold or by calculating the correlation between accuracy and awareness. However, both these methods have certain limitations. In the present article, we propose describing task accuracy and awareness as functions of stimulus intensity as suggested by Koch and Preuschoff . The estimated lag between the curves describes how much stimulus intensity must increase for awareness (...) to change proportionally as much as accuracy and the slopes of the curves are used to assess how fast accuracy and awareness increases and whether awareness is dichotomous. The method is successfully employed to assess consciousness characteristics on data from four different awareness scales. (shrink)

W. D. Ross is commonly considered to be a generalist about prima facie duty but a particularist about absolute duty. That is, many philosophers hold that Ross accepts that there are true moral principles involving prima facie duty but denies that there are any true moral principles involving absolute duty. I agree with the former claim: Ross surely accepts prima facie moral principles. However, in this paper, I challenge the latter claim. Ross, I argue, is no more a particularist about (...) absolute duty than a utilitarian or a Kantian is. While this conclusion is interesting in its own right, it is also important, I argue, because it prevents us from overlooking Ross's criterion of moral obligation and because it may have implications on the broader debate between particularists and generalists.

The paper addresses an understudied but highly relevant group of people within corporate organizations and society in general—the marginalized—as well as their narration, and criticism, of personal lived experiences of marginalization in business. They are conventionally perceived to lack traditional forms of power such as public influence, formal authority, education, money, and political positions; however, they still possess the resources to impact their situations, their circumstances, and the structures that determine their situations. Business ethics researchers seldom consider marginalized people’s voices (...) and experiences as resources to understand their lives, as demonstrated through a review of 7500 articles published in the Journal of Business Ethics and Business Ethics Quarterly (2000–2019). Only 78 studies included aspects of marginalized groups. 69 of those studies discussed the topic of marginalized groups of people, but without integrating their explicit voices into the text. Only 9 of the 78 articles featured marginalized people’s explicit voices about their marginalization experiences incorporated into the text as a source for exploration. None of the identified studies discussed the potential for theorizing based on such voices. This paper contributes to business ethics theory by developing four theoretical possibilities vis-à-vis the critical voices of marginalized people’s experiences in business: (a) marginalized theory on critical agency and freedom of speech; (b) the gatekeeping role of academia; (c) primary sources; and (d) a participative perspective. Discussing the theoretical potential of quoting the above voices can enrich business ethics research in terms of the theoretical understanding of marginalized groups in business. (shrink)

After the cultural explosion of Web 2.0, digital culture reveals an apparently semiotic paradox associated with the incredibly widespread use of images of faces, while at the same time the reason to trust in the authenticity of these faces is constantly declining. This is because graphic technology has made the sophisticated manipulation of images both possible and easy. After a review of the existing semiotic models and considerations of trust, I am proposing a new approach which emphasizes the value-generating properties (...) of trust by analogy with the money sign, seen as “trust inscribed”. Research from the neurosciences supports the hypothesis that the trustworthiness of the face is judged pre-reflexively and primordially. This, therefore, means that a trustworthy face is a premise for more successful communication than an untrustworthy one, notwithstanding the object of discussion and the cultural context. An example concerning social media influencers serves to show that in the internet-dominated globalizing culture, trustworthy faces are a multipurpose communicative asset that makes a difference.

Comparison of behavioural measures of consciousness has attracted much attention recently. In a recent article, Szczepanowski et al. conclude that confidence ratings predict accuracy better than both the perceptual awareness scale and post-decision wagering when using stimuli with emotional content . Although we find the study interesting, we disagree with the conclusion that CR is superior to PAS because of two methodological issues. First, the conclusion is not based on a formal test. We performed this test and found no evidence (...) that CR predicted accuracy better than PAS . Second, Szczepanowski et al. used the present version of PAS in a manner somewhat different from how it was originally intended, and the participants may not have been adequately instructed. We end our commentary with a set of recommendations for future studies using PAS. (shrink)

According to the standard view, the so-called ‘Copenhagen interpretation’ of quantum mechanics originated in discussions between Bohr and Heisenberg in 1927, and was defended by Bohr in his classic debate with Einstein. Yet recent scholarship has shown Bohr’s views were never widely accepted, let alone properly understood, by his contemporaries, many of whom held divergent views of the ‘Copenhagen orthodoxy’. This paper examines how the ‘myth of the Copenhagen interpretation’ was constructed by situating it in the context of Soviet Marxist (...) critique of quantum mechanics in the 1950s and the response by physicists such as Heisenberg and Rosenfeld.

This paper discusses a class of mechanistic explanations employed in engineering science where the activities and organization of nonstandard entities are cited as core factors responsible for failures. Given the use of mechanistic language by engineers and the manifestly mechanistic structure of these explanations, I consider several interpretations of these explanations within the new mechanical framework. I argue that these interpretations fail to solve several philosophical problems and propose an account of fictional mechanism explanations instead. According to this account, fictional (...) mechanism explanations provide descriptions of fictional mechanisms that enable the tracking of counterfactual dependencies of the physical system they model by capturing system constraints. Engineers use these models to learn about and understand properties of materials, to build computational simulations of their behaviour, and to design new materials. (shrink)

In this article I will describe the main elements of the Norwegian press’s moral confrontation with the Government Pension Fund’s ethical investment management when it was in an introductory phase in early 2005, with special emphasis on one newspaper, Stavanger Aftenblad. The press criticized the fund’s fresh investment profile and intended exclusionary practice before it had really started in earnest. Then I will focus on how the press’s unilateral criticism of the fund’s investment practice at the time overshadowed a discussion (...) of any defects in the ethical principles for investment. And I will focus on the press’s lack of distinguishing between information and sensation. In conclusion I point out that in 2006 the press has abandoned its critical stance from 2005 and has now a tendency to idealize the fund’s exclusionary practice and the underlying principles.

In their comment on Sandberg, Timmermans, Overgaard, and Cleeremans , Dienes and Seth argue that increased sensitivity of the Perceptual Awareness Scale is a consequence of the scale being less exclusive rather than more exhaustive. According to Dienes and Seth, this is because PAS may measure some conscious content, though not necessarily relevant conscious content, “If one saw a square but was only aware of seeing a flash of something, then one has not consciously seen a square.” In this reply, (...) we claim that there is a difference between conscious visual experience, which may be partial, and the resulting conscious content, which is conceptual. Whereas PAS measures the first, confidence judgments and post-decision wagering measure the second. (shrink)

The aim of this paper is to consider whether some seats in a democratically elected legislative assembly ought to be reserved for representatives of future generations. In order to examine this question, I will propose a new democratic model for representing posterity. It is argued that this model has several advantages compared with a model for the democratic representation of future people previously suggested by Andrew Dobson. Nevertheless, the democratic model that I propose confronts at least two difficult problems. First, (...) it faces insoluble problems of representative legitimacy. Second, one might question whether this model provides a reasonably effective way to represent future interests compared with existing representative democratic institutions. Despite such problems, it is argued that political representation of posterity can be defended on the basis of fundamental ideas and ideals in recent theory of deliberative democracy. The first reason for this is that in a number of cases democratic decisions cannot be regarded as normatively legitimate from the point of view of deliberative democracy, unless posterity is given a voice. The second reason is that representation of posterity can contribute to more rational and impartial deliberations and decisions in legislative assemblies. (shrink)

The purpose of this article is to consider the question of whether democratic legitimacy requires viewpoint neutrality with regard to political speech – including extremist political speech, such as hate speech. The starting point of my discussion is Jeremy Waldron’s negative answer to this question. He argues that it is permissible for liberal democracies to ban certain extremist viewpoints – such as vituperative hate speech – because such viewpoint-based restrictions protect the dignity of persons and a social and moral environment (...) of mutual respect. According to Waldron, well-drafted narrow hate speech bans are not democratically illegitimate, and they do not undermine systemic democratic legitimacy – that is, the legitimacy of a democratic political system. In contrast to Waldron, I will argue that democratic legitimacy requires viewpoint neutrality to respect persons as thinking agents. I will defend a civil libertarian doctrine of viewpoint neutrality, and this doctrine requires that citizens in liberal democracies ought to have a legal free speech right to do moral wrong – that is, a legal right to express and defend any political viewpoint or idea, even if it is morally wrong to express, or expose others to, such views. It will be argued that any viewpoint-based restriction on public discourse is democratically illegitimate, and that such restrictions undermine systemic democratic legitimacy. (shrink)

The present study focuses on meeting online strangers face-to-face. This activity represents one of the least prevalent but also most feared online risks for youth. Due to the low number of youth experiencing upsetting meetings and the dominance of quantitative research designs in the area, the current state of knowledge does not provide a clear view of what happens at meetings that youths find upsetting. The aim of the present study is to enrich knowledge in this area by exploring such (...) upsetting experiences in more depth by using qualitative methodology. Based on 14 interviews with Czech girls aged 15 to 18, who reported upsetting meetings with online strangers, the study identifies the discrepancy between expectations and reality as the core reason for these negative feelings. There were several reasons for this discrepancy: different developmental phases, related different experiences with romantic relationships, and exaggeration of impressions formed online. (shrink)

The critical and polemic receptions of the work of Loïc Wacquant has been extensive, but to a large extent focused on specific works and colored by professional specialty, that is, in a word: fragmented. In counteracting that fragmented response, the article sheds light on the undercurrents in Wacquant’s works by stressing four prominent and consistent features: his heritage from Bourdieu; his emphasis on and constant practice of theory ; the distinct ethos with which he addresses political sociology ; and finally, (...) the persistent and ubiquitous critique of everything in existence – a thematic indicator permeating each and every one of his works. Thus the article proposes a unifying reading of Wacquant as an interpretation advocating revitalization of a critical social science. (shrink)

This book is about the work of 10 great scientists; who they were and are, their personal background and how they achieved their outstanding results and took their prominent place in science history. We follow one of physics and science history's most enigmatic phenomena, superconductivity, through 100 years, from its discovery in 1911 to the present, not as a history book in the usual sense, but through close ups of the leading characters and their role in that story, the Nobel (...) laureates, who were still among us in the years 2001-2004 when the main round of interviews was carried out. Since then two of them already passed away. For each one of the 10 laureates, the author tells their story by direct quotation from interviews in their own words. Each chapter treats one laureate. The author first gives a brief account of the laureates' scientific background and main contribution. Then each laureate tells his own story in his own words. This book is unique in its approach to science history. (shrink)

Paradigm Found brings together papers by renowned researchers from across Europe, Asia and America to discuss a selection of pressing issues in current archaeological theory and method. The book also reviews the effects and potential of various theoretical stances in the context of prehistoric archaeology. The 23 papers provide a discussion of the issues currently re-appearing in the focal point of theoretical debates in archaeology such as the role of the discipline in the present-day society, problems of interpretation in archaeology, (...) approaches to the study of social evolution, as well as current insights into issues in classification and construction of typologies. Taking a fresh, and often provocative, look at the challenges contemporary archaeology is facing, the contributors evaluate the effects of past developments and discuss the impact they are likely to have on future directions in archaeology as an internationally connected discipline. In its final part the volume reflects on current thinking on prehistory, using case-studies from a number of European regions and the Mediterranean, from the Neolithic to the Roman Period. The volume represents a tribute to the lifetime achievements of Professor Ev_en Neustupn_, a distinguished Czech archaeologist who contributed to the advancement of prehistoric studies in Europe and to archaeological theory and method in particular.

Caesarean delivery is a common and life-saving intervention. However, it involves an overall increased risk for short-term and long-term complications for both mother and child compared with vaginal delivery. From a medical point of view, healthcare professionals should, therefore, not recommend caesarean sections without any anticipated medical benefit. Consequently, caesarean sections requested by women for maternal reasons can cause conflict between professional recommendations and maternal autonomy. How can we assure ethically justified decisions in the case of caesarean sections on maternal (...) request in healthcare systems that also respect patients’ autonomy and aspire for shared decisions? In the maternal–professional relationship, which can be characterised in terms of reciprocal obligations and rights, women may not be entitled to demand a C-section. Nevertheless, women have a right to respect for their deliberative capacity in the decision-making process. How should we deal with a situation of non-agreement between a woman and healthcare professional when the woman requests a caesarean section in the absence of obvious medical indications? In this paper, we illustrate how the maternal–professional relationship is embedded in a nexus of power, trust and risk that reinforces a structural inferiority for women. To accommodate for beneficial use of power, these decision processes need to be trustworthy. We propose a framework, inspired by Lukes’ three-dimensional notion of power, which serves to facilitate trust and allows for beneficial power in shared processes of decision-making about the delivery mode for women requesting planned C-sections.

This paper presents a critical analysis of Tamar Szabó Gendler’s view of thought experiments, with the aim of developing further a constructivist epistemology of thought experiments in science. While the execution of a thought experiment cannot be reduced to standard forms of inductive and deductive inference, in the process of working though a thought experiment, a logical argument does emerge and take shape. Taking Gendler’s work as a point of departure, I argue that performing a thought experiment involves a process (...) of self-interrogation, in which we are compelled to reflect on our pre-existing knowledge of the world. In doing so, we are forced to make judgments about what assumptions we see as relevant and how they apply to an imaginary scenario. This brings to light the extent to which certain forms of skill, beyond the ability to make valid logical inferences, are necessary to execute a thought experiment well. (shrink)

The way our decisions and actions can affect future generations is surrounded by uncertainty. This is evident in current discussions of environmental risks related to global climate change, biotechnology and the use and storage of nuclear energy. The aim of this paper is to consider more closely how uncertainty affects our moral responsibility to future generations, and to what extent moral agents can be held responsible for activities that inflict risks on future people. It is argued that our moral responsibility (...) to posterity is limited because our ability to foresee how present decisions and activities will affect future people is limited. The reason for this is primarily that we are in a situation of ignorance regarding the pace and direction of future scientific and technological development. This ignorance reduces our responsibility in a temporal dimension because in most areas it is impossible to predict the interests and resource needs of future generations. In one area, however, we have fairly reliable knowledge about future people. It is reasonable to assume that future human beings will have the same basic physiological (physical and biological) needs as we have. On this basis, it is argued that we can be held responsible for activities causing avoidable damage to critical resources that are necessary to provide for future physiological needs. Furthermore, it is suggested that it is prima facie immoral to impose risks upon future generations in cases where the following conditions are fulfilled: (1) the risk poses a threat to the ability of future generations to meet their physiological needs, and (2) the risk assessment is supported by scientifically based harm scenarios.
