Many approaches to addressing labour injustices—shortfalls from minimally decent wages and working conditions— focus on how governments should orient themselves toward other states in which such phenomena take place, or to the firms that are involved with such practices. But of course the question of how to regard such labour practices must also be faced by individuals, and individual consumers of the goods that are produced through these practices in particular. Consumers have become increasingly aware of their connections to complex (...) global production processes that often involve such injustice. For example, activist campaigns have exposed wrongful harm in factories producing clothes, shoes and mobile phones and farms producing coffee, tea and cocoa. These campaigns have promoted the message to ordinary people that by becoming connected to unjust labour practices through their purchasing behaviour, they acquire special additional moral responsibilities to contribute to reforming such practices, or to address the hardships suffered by the victims of the wrongdoing that result from them. The moral significance of the responsibilities of individual consumers has not, however, received much analytical scrutiny. Why should we believe that there are such responsibilities? And if there are such responsibilities, what are their grounds? How stringent are the responsibilities triggered by such connections? Finally, what are the implications of such responsibilities—the courses of action that they prescribe or proscribe? The activists who assert special ethical responsibilities for consumers have promoted many particular courses of action, but have seldom articulated the grounds of these responsibilities or explained why they should be taken to be stringent. And moral and political theorists have not devoted much focussed attention to this issue. For the consumer who is concerned to act in a morally permissible way, this presents a troubling practical challenge regarding the goods they may (or may not) purchase, and the moral relevance of their consumption choices more generally. While we cannot address all of these pressing questions in this chapter, we try to make some headway with them by discussing two general approaches to the question of how individuals should conceive of their responsibilities with respect to such practices, taking as our starting point the recent work of the late Iris Marion Young—the most sustained treatment of this topic by a prominent political theorist. In a series of influential articles and a posthumously published book, Young articulated an approach to conceiving of individual responsibilities to address labour injustices—the social connection model—at home and abroad. She also argued that an alternative model—the liability model—which she claimed had dominated discourse on this topic, suffered from very serious flaws. In a critical vein, we will argue that Young’s arguments against the liability model are not convincing, and that the alternative she proposes is itself vulnerable to some damaging objections. We also find, however, that the liability model would need to be extended in various ways to provide an adequate account of individual responsibility to address shortfalls from minimally decent wages and working conditions, and we begin the task of sketching an extended framework.

How did I raise my arm? The simple answer is that I raised it as a consequence of intending to raise it. A slightly more complicated response would mention the absence of any factors which would inhibit the execution of the intention- and a more complicated one still would specify the intention in terms of a goal (say, drinking a beer) which requires arm-raising as a means towards that end. Whatever the complications, the simple answer appears to be on the (...) right track. (shrink)

This article presents an axiological reading of Simone de Beauvoir’s The Second Sex, reframing its most famous sentence ‘one is not born, but becomes, a woman’ as a claim about femininity, love, and alienation under particular conditions of sexual hierarchy. Because this sentence is often taken to express the thesis of The Second Sex on social constructionist readings, Section 1 rejects the aptness of this approach on three grounds. Section 2 outlines an alternative, axiological reading, which better attends to all (...) of the work’s parts, and to Beauvoir’s emphasis on the concrete inseparability of the physiological, sexual, economic, legal, religious, moral, and aesthetic dimensions of women’s situations. Section 3 turns to the sister ‘one is not born’ clause, in Volume I—‘one is not born, but becomes, a genius’—to show that Beauvoir’s account of frustrated freedom in The Second Sex concerns not only alienated labour, sex, and love, but also aesthetic creativity and moral invention.

This chapter contains section titles: Introduction Section 1 Section 2 Conclusion.

In this article, I outline a strategy for challenging J.L. Schellenberg’s hiddenness argument, and specifically the premise within the argument that asserts the existence of what Schellenberg calls nonresistant nonbelief. Drawing on some of the philosophical resources of skeptical theism, I show how this premise is based on a particular “noseeum assumption”—what I call Schellenberg’s Noseeum Assumption—that underwrites a particular “noseeum argument.” This assumption is that, regarding putative nonresistant nonbelievers, more likely than not we’d detect these nonbelievers’ resistance toward God (...) if there were any. I give reasons for thinking that it is not more reasonable to affirm than to refrain from affirming Schellenberg’s Noseeum Assumption, and so reason to think that the hiddenness argument is not a good argument for atheism. I also defend the strategy I outline against several objections. (shrink)

Meaning-making plays a central role in how we deal with experiences of suffering, including those due to mental disorder. And for many, religious beliefs, experiences, and practices (hereafter, religious engagement) play a central role in informing this meaning-making. However, a crucial facet of the relationship between experiences of mental disorder and religious engagement remains underexplored—namely the potentially positive effects of mental disorder on religious engagement (e.g. experiences of bipolar disorder increasing sense of God’s presence). In what follows, I will present (...) empirical findings from two recent studies of mine which shed light on the extent to which participants experienced these positive effects, specific components of these effects, and how they fit into their understanding of their mental disorder and its relationship to their religious identity. In doing so, I will draw on and expand Tasia Scrutton’s Potentially Transformative view (2015a, 2015b, 2020) according to which mental disorders may provide opportunities for spiritual growth. My empirical results align with and help deepen an account according to which mental disorders are potentially spiritually transformative by providing further insight into such instances: specifically, which symptoms and internal and external factors are often involved, as well as which religious beliefs, experiences, and/or practices are often affected. After presenting these results and articulating their relevance for a potentially transformative view of mental disorder, I will then address some potential objections to the theoretical account as well as some limitations of the empirical work, before sketching possible promising directions for future research.

Charges of inconsistency are frequently made against opponents of abortion for failing to ‘live out’ their beliefs. One such popular charge is that opponents of abortion are inconsistent for failing to ‘adopt the babies they don’t want aborted’—in this chapter, I will focus on a slightly broader version of this charge. I will understand adoption* broadly to include adopting and/or fostering children, as well as concretely supporting the systems involved in facilitating adoption and foster care through financial means, volunteering, and/or (...) advocacy. I will argue that opponents of abortion do not have special obligations to adopt* for the reasons often presumed, and thus are not inconsistent for failing to do so. However, I will go on to argue that they nevertheless have compelling reasons to do so—to decrease future abortions and oppose abortion with integrity. (shrink)

What is knowledge of one's own current, consciously entertained intentional states a form of inner awareness? If so, what form? In this paper I explore the prospects for a quasi-observational account of a certain class of cases where subjects appear to have self-knowledge, namely, the so-called cogito-like cases. In section one I provide a rationale for the claim that we need an epistemology of self-knowledge, and specifically, an epistemology of the cogito-like cases. In section two I argue that contentful properties (...) in such cases have two features in common with observational properties of objects. In section three, I develop a quasi-observational account of self-knowledge for the cogito-like cases by considering various accounts of the nature of observational properties and by applying them to these cases. I conclude by addressing some important objections to the account. (shrink)

Cognitive Penetration holds that cognitive states and processes, specifically propositional attitudes (e.g., beliefs), sometimes directly impact features of perceptual experiences (e.g., the coloring of an object). In contrast, more traditional views hold that propositional attitudes do not directly impact perceptual experiences, but rather are only involved in interpreting or judging these experiences. Understandably, Cognitive Penetration is controversial and has been criticized on both theoretical and empirical grounds. I focus on defending it from the latter kind of objection and in doing (...) so, highlight important features of Cognitive Penetration mechanisms and effects. I first sketch promising criteria for Cognitive Penetration and then address widespread Replication and Demonstration worries about purported instances of it. Next, I present one of the most compelling Cognitive Penetration studies and address specific objections against it and others. I demonstrate that each of these objections misunderstands important features of either Cognitive Penetration mechanisms or the specific studies to which they are applied. Ultimately, I conclude that multiple key studies are not undermined by these objections and con- tinue to provide support for Cognitive Penetration. Correcting these misunderstandings bolsters empirical support for Cognitive Penetration and contributes to a better understand- ing of the mechanisms involved in perceptual processing. (shrink)

Thomas Pogge’s (2006) framework of global justice can be adapted for individual agents or collective unilateral donations in the same way Peter Singer’s framework has been. I do so by amending Pogge’s institutional principles for international human rights NGOs and by adding two further principles to address challenges that arise when his framework is applied. This adapted framework enjoins donors to make principled philanthropic decisions that prioritize existing and near-term suffering, while also rectifying their part in causing this suffering. It (...) makes Pogge’s negative duty account easier to implement than his previous proposal, and provides well-off individuals with an alternative to Effective Altruism. (shrink)

It is widely accepted that physicalism faces its most serious challenge when it comes to making room for the phenomenal character of psychological experience, its so-called what-it-is-like aspect. The challenge has surfaced repeatedly over the past two decades in a variety of forms. In a particularly striking one, Frank Jackson considers a situation in which Mary, a brilliant scientist who knows all the physical facts there are to know about psychological experience, has spent the whole of her life in a (...) black and white room. He asks, What will happen when Mary is released from her black and white room or is given a colour television monitor? Will she learn anything or not? It seems just obvious that she will learn something about the world and our visual experience of it. But then it is inescapable that her previous knowledge was incomplete. But she had all the physical information. (Jackson 1986: 130). (shrink)

Conflict over who belongs in women-only spaces is now part of mainstream political debate. Some think women-only spaces should exclude on the basis of sex, and others think they should exclude on the basis of a person’s self-determined gender identity. Many who take the latter view appear to believe that the only reason for taking the former view could be antipathy towards men who identify as women. In this paper, we’ll revisit the second-wave feminist literature on separatism, in order to (...) uncover the reasons for women-only spaces as feminists originally conceived them. Once these reasons are understood, those participating in debates over women-only spaces will be in a better position to adjudicate on whether shifting from sex to gender identity puts any significant interests at stake.

(Penultimate draft) Embodied Cognition holds that bodily (e.g. sensorimotor) states and processes are directly involved in some higher-level cognitive functions (e.g. reasoning). This challenges traditional views of cognition according to which bodily states and processes are, at most, indirectly involved in higher-level cognition. Although some elements of Embodied Cognition have been integrated into mainstream cognitive science, others still face adamant resistance. In this paper, rather than straightforwardly defend Embodied Cognition against specific objections I will do the following. First, I will (...) present a concise account of embodied conceptual processing and highlight some of its advantages over non-embodied accounts, specifically focusing on the role of metaphors. Second, I will detail the influence of computational metaphors on theories of cognition and evaluation of these theories. Third, I will argue that embodied cognitive mechanisms, specifically those operating through computational metaphors, may drive some of the resistance to Embodied Cognition - and that Embodied Cognition is able to offer a uniquely compelling account of this. Ultimately, this will contribute to an improved understanding of Embodied Cognition, its explanatory power, and how it ought to be evaluated. Additionally, it will shed light on the role of metaphors in shaping philosophical thought and highlight the importance of these influences. (shrink)

Narratives structure and inform how we understand our experiences and identity, especially in instances of suffering. Suffering in mental disorder (e.g. bipolar disorder) is often uniquely distressing as it impacts capacities central to our ability to make sense of ourselves and the world—and the role of narratives in explaining and addressing these effects is well-known. For many with a mental disorder, spiritual/religious narratives shape how they understand and experience it. For most, this is because they are spiritual and/or religious. For (...) others, spiritual/religious narratives still often influence secular approaches to mental disorder, more than approaches to other disabilities (e.g. intellectual, physical) or causes of suffering (e.g. physical disease). Such narratives are often harmful, especially insofar as they ‘over-spiritualize’ mental disorder; and undercut ‘spiritual meaning-making’. Here I address the impact of spiritual/religious narratives that helpfully avoid over-spiritualizing mental disorder while enabling spiritual meaning-making about it. First, I address the role of narratives in meaning-making more generally; then, I present results from my recent empirical study testing the impact of such narratives on participants’ meaning-making about their mental disorder. I conclude by addressing implications and potential worries. (shrink)

Nature-based solutions (NbS) have in recent years occupied a central position in conservation and climate discussions among both scientists and policy makers. NbS generally refer to a set of strategies which use nature, or natural objects, to address societal (human) issues while simultaneously supporting the broader environment. This paper examines the concept of NbS to determine whether it is a useful and well-motivated category to guide future climate and conservation efforts. I argue that NbS may in fact be a valuable (...) contribution to environmental thought and policy, but not for the reasons that they are typically thought to be. Specifically: while we have reason to doubt that NbS should be prioritized over other environmental strategies on the grounds that they are uniquely environmentally-friendly or supportive of biodiversity, they may nevertheless have an advantage insofar as they play a vital aesthetic role in developing a healthier relationship between humans and the nonhuman world.

It is widely accepted that knowledge of certain of one’s own mental states is authoritative in being epistemically more secure than knowledge of the mental states of others, and theories of self-knowledge have largely appealed to one or the other of two sources to explain this special epistemic status. The first, ‘detectivist’, position, appeals to an inner perception-like basis, whereas the second, ‘constitutivist’, one, appeals to the view that the special security awarded to certain self-knowledge is a conceptual matter. I (...) argue that there is a fundamental class of cases of authoritative self-knowledge, ones in which subjects are consciously thinking about their current, conscious intentional states, that is best accounted for in terms of a theory that is, broadly speaking, introspectionist and detectivist. The position developed has an intuitive plausibility that has inspired many who work in the Cartesian tradition, and the potential to yield a single treatment of the basis of authoritative self-knowledge for both intentional states and sensation states.

Our day-to-day experience of the world regularly brings us into contact with middlesized objects such as apples, dogs, and other human beings. These objects possess observable properties, properties that are available or accessible to the unaided senses, such as redness and roundness, as well as properties that are not so available, such as chemical ones. Both of these kinds of properties serve as valuable sources of information about our familiar middle-sized objects at least to the extent that they enable us (...) to understand the behaviours of those objects and their effects on each other and on us. I see the apple on the table before me, and in doing so I see its redness, its roundness, and so on. I do not see, but know that it has, a certain chemical constitution. The knowledge gained of the apple by means of both properties tells me something about the nature of that apple. In general, most, if not all, of the properties that objects in the observable world possess serve as the basis of our knowledge of such objects. But the subject-predicate form of much of our discourse and thought about objects suggests that substances are one kind of thing, properties another. We use subject terms such as names to identify objects, predicate terms to attribute properties to them. What, then, is it for an object to have a property? And what is the relation between an object and its properties? (shrink)

The primary justification for mathematical structuralism is its capacity to explain two observations about mathematical objects, typically natural numbers. Non-eliminative structuralism attributes these features to the particular ontology of mathematics. I argue that attributing the features to an ontology of structural objects conflicts with claims often made by structuralists to the effect that their structuralist theses are versions of Quine’s ontological relativity or Putnam’s internal realism. I describe and argue for an alternative explanation for these features which instead explains the (...) attributes them to the mathematical practice of representing numbers using more concrete tokens, such as sets, strokes and so on.

An influential heuristic for thinking about climate adaptation asserts that “natural” adaptation strategies are the best ones. This heuristic has been roundly criticized but is difficult to dislodge in the absence of an alternative. We introduce a new heuristic that assesses adaptation strategies by looking at their maturity, power, and commitment. Maturity is the extent to which we understand an adaptation strategy’s effects. Power is the size of the effect an adaptation strategy will have. Commitment is the degree to which (...) an adaptation strategy is difficult to test or reverse. (shrink)

Among the works of the ancient Greek satirist Lucian of Samosata, well-known for his scathing and obscene irony, there is the novel True History. In this work Lucian, being in an intense satirical mood, intended to undermine the values of the classical world. Through a continuous parade of wonderful events, beings and situations as a substitute for the realistic approach to reality, he parodies the scientific knowledge, creating a literary model for the subsequent writers. Without doubt, nowadays, Lucian’s large influence (...) on the history of literature has been highlighted. What is missing is pointing out the specific characteristics that would lead to the placement of True History at the starting point of Science Fiction. We are going to highlight two of these features: first, the operation of “cognitive estrangement”, which aims at providing the reader with the perception of the difference between the convention and the truth, and second, the use of strange innovations (“novum”) that verify the value of Lucian’s work by connecting it to historicity.

In this entry, we survey key discussions on the role of narrative in theology and philosophy of religion. We begin with epistemological questions about whether and how narrative offers genuine understanding of reality. We explore how narrative intersects with the problems of evil and divine hiddenness. We discuss narrative's role in theological reflection and practice in general, and in black and feminist theologies specifically. We close by briefly exploring the role of narrative in theorization about life's meaning.

David Enoch, in Taking Morality Seriously, argues for a broad normative asymmetry between how we should behave when disagreeing about facts and how we should behave when disagreeing due to differing preferences. Enoch claims that moral disputes have the earmarks of a factual dispute rather than a preference dispute and that this makes more plausible a realist understanding of morality. We try to clarify what such claims would have to look like to be compelling and we resist his main conclusions.

In the present paper, the meanings the term “Chaldeans” acquired during the Antiquity and the early Middle Ages are presented, but mainly the role the Chaldean Oracles played inside the movement of Neo-Platonism is emphasized. The stratification of Being according to the theology of the Chaldean Oracles, suggests a reformation of the ancient Chaldean dogmas by the Neo-Platonists. The kernel of this paper is the demonstration of the similarity between the name “En” that the ancient Babylonians used as the first (...) part of many compound words for their gods, with the One (Ἕν=En), the first theological principle in the Neo-Platonic system. Yet, a comparison between the Chaldean theology and the Neo-platonic views on Mysticism and religiosity follows. As it is well known, the later Neo-Platonism will be led to the creation of a way of thought and practice as impacts from the ancient tradition. (shrink)

This paper sketches a Kantian account of forgiveness and argues that it is distinguished by three features. First, Kantian forgiveness is best understood as the revision of the actions one takes toward an offender, rather than a change of feeling toward an offender. Second, Kant’s claim that forgiveness is a duty of virtue tells us that we have two reasons to sometimes be forgiving: forgiveness promotes both our own moral perfection and the happiness of our moral community. Third, we have (...) a duty to withhold forgiveness if with think forgiveness will cause or encourage our offender to wrong us again. This duty to sometimes withhold forgiveness stems from our duty of self-respect, which Kant repeatedly describes as a duty to ourselves to ensure that we are not harmed again. (shrink)

Post-Traumatic Stress Disorder is a mental health condition in which the experience of a traumatic event causes a series of psychiatric and behavioral symptoms such as hypervigilance, insomnia, irritability, aggression, constricted affect, and self-destructive behavior. This paper investigates two case studies to argue that the experience of PTSD is not restricted to humans alone; we have good epistemic reason to hold that some animals can experience genuine PTSD, given our current and best clinical understanding of the disorder in humans. I (...) will use this evidence to argue for two claims. First, because the causal structure of PTSD plausibly requires reference to a traumatic conscious experience in order to explain subsequent behaviors, the fact that animals can have PTSD provides new evidence for animal consciousness. Second, the discovery of PTSD in animals puts pressure on accounts which hold that animal behavior can be fully explained without reference to subjective experience. (shrink)

Genetic testing in the workplace is a technology both full of promise and fraught with ethical peril. Though not yet common, it is likely to become increasingly so. We survey the key arguments in favour of such testing, along with the most significant ethical worries. We further propose a set of pragmatic criteria, which, if met, would make it permissible for employers to offer (but not to require) workplace genetic testing.

This chapter contains section titled: Externalism and Authoritative Self‐Knowledge The “Fully Cartesian” Conception Externalism and Authoritative Self‐Knowledge A Suggestion.

The purpose of this symposium is to explore the ways in which literature, broadly construed to include poetry and narrative in a variety of modes of representation, can change the world by providing interventions in justice. Our approach foregrounds the relationship between the activity demanded by some individual literary works and some categories of literary work on the one hand and the way in which those works can make a tangible difference to social reality on the other. We consider three (...) types of active literary engagement: doing philosophy, ideological critique, and necessary rather than contingent performance. Kate Kirkpatrick opens with Kamel Daoud’s The Meursault Investigation (2013), reading the narrator as not only a critic of colonial and postcolonial discourse but also a literary exemplar of the search for justice when it is difficult to know to what level of explanation to attribute its absence. Rafe McGregor demonstrates how the final season of Prime Video’s The Man in the High Castle (2015–19) makes a radical break from the previous three, exposing the misanthropy at the core of right-wing populism and calling for a fundamentally democratic response from the left. Finally, Karen Simecek argues that poetry in performance has a potentially reparative function for the ethically lonely – the vulnerable, the oppressed, and the persecuted – in society. (shrink)

Jean-Paul Sartre is rarely discussed in the philosophy of religion. In 2009, however, Jerome Gellman broke the silence, publishing an article in which he argued that the source of Sartre’s atheism was neither philosophical nor existential, but mystical. Drawing from several of Sartre’s works – including Being and Nothingness, Words, and a 1943 review entitled ‘A New Mystic’ – I argue that there are strong biographical and philosophical reasons to disagree with Gellman’s conclusion that Sartre was a ‘mystical atheist’. Moreover, (...) I question the likelihood of drawing any definitive conclusions regarding the sources of Sartre’s ambiguous atheism. (shrink)

An overview of what constitutes as lying and the epistemic and moral consequences lying incurs.

Entanglement has been called the most important new feature of the quantum world. It is expressed in the quantum formalism by the joint measurement formula. We prove the formula for projection valued observables from a plausible assumption, which for spacelike separated measurements is an expression of relativistic causality. The state reduction formula is simply a way to express the joint measurement formula after one measurement has been made, and its result known.

There is a consistent and simple interpretation of the quantum theory of isolated systems. The interpretation suffers no measurement problem and provides a quantum explanation of state reduction, which is usually postulated. Quantum entanglement plays an essential role in the construction of the interpretation.

We are going to present a panorama of Byzantine Philosophy. As starting point should be considered the Patristic Thought, which preceded the Byzantine Philosophy and was established in the first centuries A.D. into the Greek-Roman world. It was based on the Old and New Testament, the apostolic teachings, as well as on Judaism and Greek Philosophy. Also, the Ancient Oriental Religions – especially those of the Greek-Roman period, i.e. the Gnosticism- exerted an influence on it. The Patristic Thought and the (...) Ancient Greek Philosophy were the two main pedestals of Byzantine Philosophy. But, we cannot separate completely Patristic thought from the Byzantine Philosophy, first because the Byzantine Philosophy used all the corpus of the preceded texts of the Church Fathers and second because the Patristic Thought was continued to the end of Byzantium in interaction with Byzantine Philosophy. When we use he term Byzantine Philosophy we refer to the ideological currents that flourished from the 9th century till the 15th in the geographical area of the Greek East. Its main task was the quest for truth from the metaphysical point of view. In this era we have not only commentaries and scholastic works, but also an assimilation of the previous philosophical and scientific developments in purpose of an interior evolution. The opposition to, and the use of, the Western scholasticism were also another two special characteristics of Byzantine Thought. The use of the logical works of Aristotle and the metaphysics of Plato made up its main theoretical body, always in relation to the Christian dogmas. The logical, metaphysical, cosmological, ethical, aesthetical and anthropological subjects were closely connected with the fixed Christian view of the World, God and Man. But despite the influence of the Christian religion and the Aristotelic, Platonic, Stoic, Neoplatonic etc. teachings, today we can arrive at the conclusion that from the ninth through the fifteen century a relative autonomy of Philosophy in Byzantium was emerged. Also, the Philosophical thought in Byzantium gave some new solutions to the old problems and dared sometimes to proceed in new rational, mystical or even empirical elaborations of original philosophical questions.

This paper (i) gives necessary and sufficient conditions that clocks in an inertial lattice can be synchronized, (ii) shows that these conditions do not imply a universal light speed, and (iii) shows that the terrestrial redshift experiment provides evidence that clocks in a small inertial lattice in a gravitational field can be synchronized.

Hans C. Ohanian 1 claims to “defeat” the conventionalist thesis of clock synchronization using an argument based on dynamics. My aim here is to show that his argument does not succeed.

The article seeks to present an overview of the history of Byzantine philosophy. It takes its point of departure in the most important factors that influenced and shaped the Patristic thought. Subsequently, the paper considers the relative autonomy of Byzantine philosophy and offers a brief profile of major philosophers that contributed to the stream in the period from 9th to 15th century. From the numerous subjects that were taken into account by the most prominent Byzantine philosophers, the article discusses such (...) issues as: the view of God, the problem of ‘conceptual realism’, the relationship between such ‘disci plines’ as logic, metaphysics, ethics, aesthetics and philosophical anthro pology. Furthermore, such questions as the place of man in the world, the scope of their freedom and the problem of evil are also touched upon here. The paper concludes with some remarks on the develop ment of Byzantine philosophy after the fall of Byzantium. (shrink)

We outline a simple development of special and general relativity based on the physical meaning of the spacetime interval. The Lorentz transformation is not used.

There is no indication of time dilation of clocks or of length contraction of rods in Marzke and Wheeler's clock or in Desloge's metrosphere.

I give concise derivations of Price's equation and the criteria for kin and group selection, prove that kin and group selection are equivalent, and discuss the controversies about altruism.

In general relativity, a spacetime and a gravitational field form an indivisible unit: no field, no spacetime. This is a lesson of Einstein's hole argument. We use a simple transformation in a Schwartzschild pacetime to illustrate this.

Nanotechnology research is beginning to see widespread coverage in the media and popular science literatures, but discussions of hopes and fears about nanotechnology have already become polarised into utopian and dystopian visions. More moderate discussions focus on the near-term applications of nanotechnologies, and on potential benefits and harms. However, in exploring the social and ethical implications of nanotechnology, important lessons should be learned from experiences in other fields. In particular, studies of the ethical, legal, and social issues of genetics research (...) have successfully mapped out many of the issues that arise when new technologies are deployed. It is our contention that, for the most part, the ethical and social issues arising in nanomedicine are not altogether new, and thus do not require novel ethical principles or frameworks, nor a massive investment in ‘NELSI’ research. Instead, what is needed is support for the development of a culture of ethics amongst scientists and clinicians, basic scientific and medical knowledge for bioethicists, and a social competency for citizens to participate actively in debates about the implications of new technologies in general.
