In an age where issues like climate change and the unintended consequences of technological innovation are high on the ethical and political agenda, questions about the nature and extent of our responsibilities to future generations have never been more important, yet simultaneously so difficult to answer. This book takes a unique approach to the problem by drawing on diverse traditions of thinking about care (including developmental psychology, phenomenology and feminist ethics) to explore the nature and meaning of our relationship with (...) the future. Demonstrating that many influential perspectives on intergenerational ethics, including positions advanced by John Rawls, Brian Barry, and Ulrich Beck are undermined by problems relating to uncertainty, it shows that an approach based on care ethics can confront the uncertain future successfully and give a viable account of the nature and scope of future-oriented responsibilities.

Calls to decolonise the university and revise what we research and teach is a challenge that ought to be taken up by those working in African philosophy and philosophy in Africa, more generally. Often, the thought is that such decolonisation will involve a complete subversion, destruction or deconstruction of colonial attitudes, processes and concepts. A more moderate proposal for decolonisation of philosophy can be found, however, which is Kwasi Wiredu’s project of conceptual decolonisation. In this paper, I defend the project (...) from two categories of objection, what I call the decolonisation and methodology objections. I argue that the objections are misdirected and unfair because they fail to recognise the theoretical backing of Wiredu’s wider work. The critical reflection central to Wiredu’s project of conceptual decolonisation can be a genuinely helpful and viable route to take when tackling the challenges of decolonising philosophy. (shrink)

Edmund Husserl, the founder of modern phenomenology, always insisted that philosophy is not just a scholarly discipline, but can and must aspire to the status of a ‘strict’ or ‘rigorous science’ (strenge Wissenschaft). Heidegger, by contrast, began his winter lectures in 1929 by dismissing what he called the ‘delusion’ that philosophy was or could be either a discipline or a science as the most disastrous debasement of its innermost essence. To understand what Husserl had in mind, it is important to (...) begin by remembering that the word Wissenschaft has a wider extension than the word ‘science’. German distinguishes the Naturwissenschaften from the Geisteswissenschaften, or human sciences, which Husserl and Heidegger both believed could be perfectly ‘rigorous’ in their own way. Speakers of English, by contrast, tend to draw a threefold distinction among the natural sciences, the social sciences, and the humanities. (shrink)

Suppose we believe that God created the world. Then surely we want it to be the case that he intended, in some sense at least, to create THIS world. Moreover, most theists want to hold that God didn't just guess or hope that the world would take one course or another; rather, he KNEW precisely what was going to take place in the world he planned to create. In particular, of each person P, God knew that P was to exist. (...) Call this the "standard" conception. Most theists find the standard conception appealing. Unfortunately, the view seems to conflict with the equally appealing idea — call it "temporal actualism" — that there are no "future" individuals beyond those that already exist in the present moment. For, on this view, for any historical person P, prior to creation, there was no such person as P and hence nothing about P for God to know. Hence, in particular, God couldn't have known that P was to exist. This is of course not a new problem. But past solutions to it are highly problematic. In this paper, after canvassing previous approaches, I will propose a solution that seems to preserve both temporal actualism and a suitably robust form of the standard conception while avoiding the pitfalls of the past.

Many ethical frameworks require artificial intelligence (AI) systems to be explainable. Explainable AI (XAI) models are frequently tested for their adequacy in user studies. Since different people may have different explanatory needs, it is important that participant samples in user studies are large enough to represent the target population to enable generalizations. However, it is unclear to what extent XAI researchers reflect on and justify their sample sizes or avoid broad generalizations across people. We analyzed XAI user studies (N = (...) 220) published between 2012 and 2022. Most studies did not offer rationales for their sample sizes. Moreover, most papers generalized their conclusions beyond their target population, and there was no evidence that broader conclusions in quantitative studies were correlated with larger samples. These methodological problems can impede evaluations of whether XAI systems implement the explainability called for in ethical frameworks. We outline principles for more inclusive XAI user studies.

This 2003 book offers an interpretation of Heidegger's major work, Being and Time. Unlike those who view Heidegger as an idealist, Taylor Carman argues that Heidegger is best understood as a realist. Amongst the distinctive features of the book are an interpretation explicitly oriented within a Kantian framework and an analysis of Dasein in relation to recent theories of intentionality, notably those of Dennett and Searle. Rigorous, jargon-free and deftly argued this book will be necessary reading for all serious (...) students of Heidegger. (shrink)

We argue that while digital health technologies (e.g. artificial intelligence, smartphones, and virtual reality) present significant opportunities for improving the delivery of healthcare, key concepts that are used to evaluate and understand their impact can obscure significant ethical issues related to patient engagement and experience. Specifically, we focus on the concept of empowerment and ask whether it is adequate for addressing some significant ethical concerns that relate to digital health technologies for mental healthcare. We frame these concerns using five key (...) ethical principles for AI ethics (i.e. autonomy, beneficence, non-maleficence, justice, and explicability), which have their roots in the bioethical literature, in order to critically evaluate the role that digital health technologies will have in the future of digital healthcare.

The terminological boxes into which we press the history of philosophy often obscure deep and important differences among major figures supposedly belonging to a single school of thought. One such disparity within the phenomenological movement, often overlooked but by no means invisible, separates Merleau-Pontys Phenomenology of Perception from the Husserlian program that initially inspired it. For Merleau-Pontys phenomenology amounts to a radical, if discreet, departure not only from Husserls theory of intentionality generally, but more specifically from his account of the (...) intentional constitution of the body and its role in perceptual experience.

For synergistic interactions between humans and artificial intelligence (AI) systems, AI outputs often need to be explainable to people. Explainable AI (XAI) systems are commonly tested in human user studies. However, whether XAI researchers consider potential cultural differences in human explanatory needs remains unexplored. We highlight psychological research that found significant differences in human explanations between many people from Western, commonly individualist countries and people from non-Western, often collectivist countries. We argue that XAI research currently overlooks these variations and that (...) many popular XAI designs implicitly and problematically assume that Western explanatory needs are shared cross-culturally. Additionally, we systematically reviewed over 200 XAI user studies and found that most studies did not consider relevant cultural variations, sampled only Western populations, but drew conclusions about human-XAI interactions more generally. We also analyzed over 30 literature reviews of XAI studies. Most reviews did not mention cultural differences in explanatory needs or flag overly broad cross-cultural extrapolations of XAI user study results. Combined, our analyses provide evidence of a cultural bias toward Western populations in XAI research, highlighting an important knowledge gap regarding how culturally diverse users may respond to widely used XAI systems that future work can and should address.

In “Bayesianism, Infinite Decisions, and Binding”, Arntzenius et al. (Mind 113:251–283, 2004 ) present cases in which agents who cannot bind themselves are driven by standard decision theory to choose sequences of actions with disastrous consequences. They defend standard decision theory by arguing that if a decision rule leads agents to disaster only when they cannot bind themselves, this should not be taken to be a mark against the decision rule. I show that this claim has surprising implications for a (...) number of other debates in decision theory. I then assess the plausibility of this claim, and suggest that it should be rejected.

Aristotle attaches particular significance to the homonymy of many central concepts in philosophy and science: that is, to the diversity of ways of being common to a single general concept. His preoccupation with homonymy influences his approach to almost every subject that he considers, and it clearly structures the philosophical methodology that he employs both when criticizing others and when advancing his own positive theories. Where there is homonymy there is multiplicity: Aristotle aims to find the order within this multiplicity, (...) and believes that doing so is crucial to scientific inquiry and philosophical progress.Christopher Shields investigates and evaluates Aristotle's approach to questions about homonymy, characterizing the metaphysical and semantic commitments necessary to establish the homonymy of a given concept. Then, in a series of case-studies, Shields examines in detail some of Aristotle's principal applications of homonymy--to the body, sameness and oneness, life, goodness, and being. Shields's aim is not only to give a fuller understanding of Aristotle's methodology and to illuminate his specific doctrines in a variety of areas, but to show that this methodology remains fruitful today.

Maurice Merleau-Ponty is one of the most important philosophers of the Twentieth century. His theories of perception and the role of the body have had an enormous impact on the humanities and social sciences, yet the full scope of his contribution not only to phenomenology but philosophy generally is only now becoming clear. In this lucid and comprehensive introduction, Taylor Carman explains and assesses the full range of Merleau-Ponty’s philosophy. Beginning with an overview of Merleau-Ponty’s life and work, subsequent (...) chapters cover fundamental aspects of Merleau-Ponty’s thought, including his philosophy of perception and intentionality; the role of the body in relation to perception; philosophy of history and culture; and his writings on art and aesthetics, particularly the work of Cezanne. A final chapter considers Merleau-Ponty’s importance today, examining his philosophy in light of recent developments in philosophy of mind and cognitive science. Merleau-Ponty is essential reading for students of phenomenology, existentialism and Twentieth century philosophy. It is also ideal for anyone in the humanities and social sciences seeking an introduction to his work. (shrink)

Christopher Hookway presents a series of studies of themes from the work of the great American philosopher and pragmatist, Charles S. Peirce (1839-1913). These themes center on the question of how we are to investigate the world rationally. Hookway shows how Peirce's ideas about this continue to play an important role in contemporary philosophy.

The eclipse predictor (or Saros dial) of the Antikythera mechanism provides a wealth of astronomical information and offers practically the only possibility for a close astronomical dating of the mechanism. We apply a series of constraints, in a sort of sieve of Eratosthenes, to sequentially eliminate possibilities for the epoch date. We find that the solar eclipse of month 13 of the Saros dial almost certainly belongs to solar Saros series 44. And the eclipse predictor would work best if the (...) full Moon of month 1 of the Saros dial corresponds to May 12, 205 BCE, with the exeligmos dial set at 0. We also examine some possibilities for the theory that underlies the eclipse times on the Saros dial and find that a Babylonian-style arithmetical scheme employing an equation of center and daily velocities would match the inscribed times of day quite well. Indeed, an arithmetic scheme for the eclipse times matches the evidence somewhat better than does a trigonometric model. (shrink)

Moral error theories are often rejected by appeal to ‘companions in guilt’ arguments. The most popular form of companions in guilt argument takes epistemic reasons for belief as a ‘companion’ and proceeds by analogy. I show that this strategy fails. I claim that the companions in guilt theorist must understand epistemic reasons as evidential support relations if her argument is to be dialectically effective. I then present a dilemma. Either epistemic reasons are evidential support relations or they are not. If (...) they are not, then the companions in guilt argument fails. If they are, then a reduction of epistemic reasons to evidential support relations becomes available and, consequently, epistemic reasons cease to be a viable ‘companion’ for moral reasons. I recommend this structure of argument over existing strategies within the literature and defend my claims against recent objections from companions in guilt theorists. (shrink)

Anger has potential epistemic value in the way that it can facilitate a process of our coming to have knowledge and understanding regarding the issue about which we are angry. The nature of anger, however, may nevertheless be such that it ultimately undermines this very process. Common non-philosophical complaints about anger, for instance, often target the angry person as being somehow irrational, where an unformulated assumption is that her anger undermines her capacity to rationally engage with the issue about which (...) she is angry. Call this assumption the charge of emotional irrationality regarding anger. Such a charge is pernicious when levelled at the anger of those in positions of marginalisation or oppression, where it can threaten to silence voices on the very issue of the injustices that they face. In this paper I thus provide a much-needed interrogation of this charge. Firstly, and drawing on empirical literature on the effects of anger on decision-making, I flesh out the charge and why it poses a threat to how the epistemic value of anger has been defended. Secondly, I argue that the charge of emotional irrationality regarding anger can nevertheless be unwarranted, at least within a common context of political anger. (shrink)

In this article, we aim at presenting a thorough and comprehensive explanation of the mathematical and theoretical relation between all the aspects of Ptolemaic planetary models and their counterparts which are built according to Kepler’s first two laws. Our article also analyzes the predictive differences which arise from comparing Ptolemaic and these ideal Keplerian models, making clear distinctions between those differences which must be attributed to the structural variations between the models, and those which are due to the specific parameters (...) Ptolemy determined in the Almagest. We expect that our work will be a contribution for a better understanding not only of the Ptolemaic theories for planetary longitudes through a clearer perception of the way in which Keplerian features are present—or absent—in Ptolemy’s models, but also for a more balanced judgement of different aspects of the contribution of the first two laws of Kepler to the modern astronomical revolution.

Developing and implementing artificial intelligence (AI) systems in an ethical manner faces several challenges specific to the kind of technology at hand, including ensuring that decision-making systems making use of machine learning are just, fair, and intelligible, and are aligned with our human values. Given that values vary across cultures, an additional ethical challenge is to ensure that these AI systems are not developed according to some unquestioned but questionable assumption of universal norms but are in fact compatible with the (...) societies in which they operate. This is particularly pertinent for AI research and implementation across Africa, a ground where AI systems are and will be used but also a place with a history of imposition of outside values. In this paper, we thus critically examine one proposal for ensuring that decision-making systems are just, fair, and intelligible—that we adopt a principle of explicability to generate specific recommendations—to assess whether the principle should be adopted in an African research context. We argue that a principle of explicability not only can contribute to responsible and thoughtful development of AI that is sensitive to African interests and values, but can also advance tackling some of the computational challenges in machine learning research. In this way, the motivation for ensuring that a machine learning-based system is just, fair, and intelligible is not only to meet ethical requirements, but also to make effective progress in the field itself.

If emotions have a rational role in action, then one challenge for accounting for how we can act rationally when acting emotionally is to show how we can guide our actions by our emotional considerations, seen as reasons. In this paper, I put forward a novel proposal for how this can be so. Drawing on the interconnection between emotions, cares and caring, I argue that, as the emotional agent is a caring agent, she can be aware of the emotional consideration (...) as a pro tanto reason favouring an action choice and, even, as the reason for which she should act.

Frederick Olafson criticizes Hubert Dreyfus’s interpretation of BEING AND TIME on a number of points, including the meaning of being, the nature of intentionality, and especially the role of das Man in Heidegger’s account of social existence. But on the whole Olafson’s critique is unconvincing because it rests on an implausible account of presence and perceptual intuition in Heidegger’s early philosophy, and because Olafson maintains an overly individuated notion of Dasein and consequently a one-sided conception of the role of das (...) Man. Unfortunately, since Dreyfus confines his commentary exclusively to Division I, he in effect forgoes any attempt to explain how das Man might be understood as playing the simultaneously constitutive and destructive role Heidegger evidently envisioned for it. I conclude by arguing that the conformity and the conformism represented by das Man are bound together by Heidegger’s notion of standoffishness (Abständigkeit). (shrink)

Intentaremos mostrar que esta asunción es incorrecta.

La base de contrastación de una teoría no tiene por qué coincidir con el (...) explanandum de la teoría. Para defender este punto se asumirá el estructuralismo metateórico. Se extraerán consecuencias para la concepción metateórica presupuesta. Palabras claves: Explicación; contrastación; T-teoricidad; Estructuralismo metateórico; Distinción teórico observacional -/- Title: Explain and test Abstract: It is usually held that one distinction can account for the role that concepts play in a theory regarding both test and explanation. We will demonstrate that this assumption is incorrect. On the one hand, there is no reason to think that this coincidence should exist. On the other, this is not the case, as we will show analysing several examples. The testing basis of a theory does not have to coincide with the explanandum of the theory. To defend this point we will endorse de metatheoretical structuralism. In addition, we will consider some repercussions that this discussion has for the assumed metatheoretical framework.

Maurice Merleau-Ponty was described by Paul Ricoeur as 'the greatest of the French phenomenologists'. The essays in this volume examine the full scope of Merleau-Ponty's philosophy, from his central and abiding concern with the nature of perception and the bodily constitution of intentionality to his reflections on science, nature, art, history, and politics. The authors explore the historical origins and context of his thought as well as its continuing relevance to contemporary work in phenomenology, philosophy of mind, cognitive science, biology, (...) art criticism and political and social theory. What emerges is a fresh image of Merleau-Ponty as a deep and original thinker whose philosophical importance has been underestimated, in part owing to the influence of intellectual movements such as existentialism and structuralism, into which his work could not be easily assimilated. New readers will find this the most convenient and accessible guide to Merleau-Ponty currently available. (shrink)

Business ethics as a field of academic endeavour has made significant progress over the past two or three decades. It now boasts a substantial body of scholarly literature, which is a major resource in which much time and effort have been invested and from which much can be gained. However, there is still much work to be done, and the dynamic nature of both academic life and the world beyond it ensures that new issues and opportunities will continue to emerge. (...) Business ethicists, individually and collectively, through the allocation of their limited research resources, will govern how well the field progresses and meets future challenges over the years to come. In particular, through our decisions about what we do or do not study and write about, we will determine the future shape of the scholarly literature – what it addresses successfully and on what it remains silent or inadequate. Implicitly or explicitly, individually and collectively, choices are made, and some are presumably better than others. This paper is a reflection on the progress of business ethics as an academic enterprise. Of course, the development of business ethics as a focus of academic interest has been marked by several review papers already, some reflecting underlying concerns consistent with Enderle’s comment that “in its present stage of development, business ethics appears to be far from being an established academic discipline”. Some might question whether something like business ethics can ever be an academic discipline as such, and for the purposes of this paper it will be helpful to distinguish between disciplines – such as philosophy, economics and psychology – and fields to which the concepts and methods of academic disciplines can be applied. Nevertheless, whatever kind of academic activity business ethics is taken to be, there are significant issues relating to its academic status. (shrink)

If emotions provide reasons for action through their intentional content, as is often argued, where does this leave the role of the affective element of an emotion? Can it be more than a motivator and have significant bearing of its own on our emotional actions, as actions done for reasons? One way it can is through reinforcing other reasons that we might have, as Greenspan argues. Central to Greenspan’s account is the claim that the affective discomfort of an emotion, as (...) a fact about the agent’s state of being, provides an additional normative reason to act to alleviate the state. This, I argue, is not correct, nor is it the best way to understand emotions as reason-reinforcers. In this paper, I thus do two things: I provide an examination of how and why the affect of emotion could provide reasons to act to alleviate it and I propose that the real way emotions reinforce reasons is through the way they orient our attention onto things that matter, registering them as salient.

Assuming that moral enhancement is morally permissible, I contend that a more careful theoretical treatment of emotion and the affective landscape is needed to advance both our understanding and the prospects of interventions aimed at moral enhancement. Using Douglas’ proposal for the direct modulation of counter‐moral emotions as a foil for discussion, I argue that the direct modulation of emotion fails to address underlying aspects of an agent’s psychology that will give rise to a range of counter‐moral motives beyond the (...) emotion that is targeted. This is because the direct modulation of emotion does not accommodate the fact that an emotional episode or emotional disposition is part of a network of other dispositions and responses, against a backdrop of our having cares and goals, as well as other cognitive content that can mediate how we apprehend a situation. By focusing on emotion rather than on moral capacity as other critiques have done, I thus argue that direct modulation is likely to be ineffective, and, more positively, by drawing out patterns of connections across the affective landscape, we can better tease out what it is that we should really be targeting if we are to achieve robust and meaningful moral change.

Plato's Utopia Recast is an illuminating reappraisal of Plato's later works, which reveals radical changes in his ethical and political theory. Christopher Bobonich examines later dialogues, with a special emphasis upon the Laws, and argues that in these late works, Plato both rethinks and revises the basic ethical and poltical positions that he held in his better-known earlier works, such as the Republic. This book will change our understanding of Plato. His controversial moral and political theory, so influential in (...) Western thought, will henceforth be seen in a new light. (shrink)

The gravitational influence of Jupiter on Saturn produces, among other things, non-negligible changes in the eccentricity of Saturn that affect the magnitude of error of Ptolemaic astronomy. The value that Ptolemy obtained for the eccentricity of Saturn is a good approximation of the real eccentricity—including the perturbation of Jupiter—that Saturn had during the time of Ptolemy's planetary observations or a bit earlier. Therefore, it seems more probable that the observations used for obtaining the eccentricity of Saturn were done near Ptolemy’s (...) time, and rather unlikely earlier than the first century AD. Even if this is not quite a demonstration that Ptolemy used observations of his own, my argument increases its probability and practically discards the idea that Ptolemy borrowed values or observations from astronomers further back than the first century AD, such as Hipparchus or the Babylonians.

In apparent motion experiments, participants are presented with what is in fact a succession of two brief stationary stimuli at two different locations, but they report an impression of movement. Philosophers have recently debated whether apparent motion provides evidence in favour of a particular account of the nature of temporal experience. I argue that the existing discussion in this area is premised on a mistaken view of the phenomenology of apparent motion and, as a result, the space of possible philosophical (...) positions has not yet been fully explored. In particular, I argue that the existence of apparent motion is compatible with an account of the nature of temporal experience that involves a version of direct realism. In doing so, I also argue against two other claims often made about apparent motion, viz. that apparent motion is the psychological phenomenon that underlies motion experience in the cinema, and that apparent motion is subjectively indistinguishable from real motion.

The psychological writing of Jung and the post-Jungians is all too often ignored as anachronistic, archaic and mystic. In Jung and the Postmodern, Christopher Hauke challenges this, arguing that Jungian psychology is more relevant now than ever before - not only can it be a response to modernity, but it can offer a critique of modernity and Enlightenment values which brings it in line with the postmodern critique of contemporary culture. After introducing Jungians to postmodern themes in Jameson, Baudrillard, (...) Jencks and Foucault, the author introduces postmodernists to Jung's cultural critique and post-Jungian discussions of representation, individuation, consciousness, and the alternatives to Enlightenment rationality. He also takes a totally fresh approach to topics such as hysteria and the body, Jung and Nietzsche, architecture and affect, Princess Diana and the 'death' of the subject, postmodern science and synchronicity, and to psychosis and alternative 'rationalities'. Jung and the Postmodern is vital reading for everyone interested in contemporary culture, not only Jungians and other psychotherapists who want to explore the social relevance of their discipline, but anyone who shares a assionate concern for where we are heading in postmodern times.

Throughout the Works and Days (WD), Hesiod reaffirms and promotes his audience’s belief in the reality of the supernatural — that is, the gods of Olympus, whose power the poet clearly takes seriously, given the somber warnings that populate the final calendrical portion of the piece. Drawing on S.I. Johnston’s recent The Story of Myth, as well as the work of folklorists K. Hänninen and G. Bennett, I outline the techniques Hesiod employs to render believable the influence of the divine (...) in both the distant past and the contemporary period. Hesiod constructs a story world familiar to his audience in order to bolster the credibility of the supernatural events, both mythical and contemporary, that he reports. When speaking of the gods’ influence in his own time, Hesiod remains firm on the fact of the gods’ continued intervention only in concrete, mundane phenomena experienced by each of his audience members. Otherwise, the poet tends toward vague language, leaving his audience to come to their own conclusion about the influence of the divine. To encourage a positive conclusion, Hesiod creates an analogy between abstract concepts, such as Strife, and the anthropomorphic gods of myth. Using these strategies, Hesiod imbues WD with belief in divine influence in the world, past and present. (shrink)

In the third century b.c.e., Eratosthenes of Cyrene made a famous measurement of the circumference of the Earth. This was not the first such measurement, but it is the earliest for which significant details are preserved. Cleomedes gives a short account of Eratosthenes’ method, his numerical assumptions, and the final result of 250,000 stades. However, many ancient sources attribute to Eratosthenes a result of 252,000 stades. Historians have attempted to explain the second result by supposing that Eratosthenes later made better (...) measurements and revised his estimate or that the original result was simply rounded to 252,000 to have a number conveniently divisible by 60 or by 360. These explanations are speculative and untestable. However, Eratosthenes’ estimates of the distances of the Sun and Moon from the Earth are preserved in the doxographical literature. This essay shows that Eratosthenes’ result of 252,000 stades for the Earth’s circumference follows from a solar distance that is attributed to him. Thus it appears that Eratosthenes computed not only a lower limit for the size of the Earth, based on the assumption that the Sun is at infinity, but also an upper limit, based on the assumption that the Sun is at a finite distance. The essay discusses the consequences for our understanding of his program. (shrink)
