James J. Gibson is one of the best known and perhaps most controversial visual theorists of the twentieth century. Writing in the vein of the American functionalists, and immersed in their profound sense of pragmatism, Gibson sought to establish a more rigorous foundation for the study of vision by reworking its most fundamental concepts. Over the five decades of his distinguished career, Gibson brought new clarity to the old problems of the tradition. He offered an alternative theory of perception (...) - one that could accommodate the experimental insights of contemporary research programs. He characterized this new theory as a version of direct perception in order to distinguish it from the traditional indirect approach of Rene Descartes. On Descartes' account, our perceptual awareness of reality comes through the representations we have formed of it within ourselves. In contrast, Gibson's theory of direct perception states that the environment contains all of the information needed to specify its properties. Hence, perceiving these properties is a matter of detecting the information available in the environment. This theory avoids the difficulty of explaining how the mind organizes holistic perceptions from atomic sensations. In what follows, I will attempt to make good these claims by situating the concept of "structure" at the heart of the ecological program. I will argue that this concept is significant precisely because it allows Gibson to locate the moving, perceiving body at the heart of meaningful perceptual experience; an experience which emerges in the dynamical structures that cross the body and the world.

The problem of whether perception is direct or if it depends on additional, cognitive contributions made by the perceiving subject, is posed with particular force in an Essay towards a New Theory of Vision. It is evident from the recurrent treatment it receives therein that Berkeley considers it to be one of the central issues concerning perception. Fittingly, the NTV devotes the most attention to it. In this essay, I deal exclusively with Berkeley's treatment of the problem of indirect distance (...) perception, as it is presented in the context of that work. (shrink)

This paper uses a reconstruction of the life and career of Heinrich Poll as a window into developments and professional relationships in the biological sciences in Germany in the period from the beginning of the twentieth century to the Nazi seizure of power in 1933. Poll's intellectual work involved an early transition from morphometric physical anthropology to comparative evolutionary studies, and also found expression in twin research - a field in which he was an acknowledged early pioneer. His advocacy of (...) eugenics led to participation in state-sponsored committees convened to advise on social policy, one of which debated sterilisation and made recommendations that led eventually to the establishment of the notorious Kaiser Wilhelm Institute for Anthropology, Human Heredity and Eugenics. However, his status as a prominent geneticist and, in particular, as a eugenicist had an ironic and ultimately tragic dimension. Heinrich Poll was of Jewish birth, and this resulted in his career being destroyed by an application of the population policies he had helped put in place. (shrink)

Two books bound together, from the religious period of one of the most renowned and representative thinkers. Written for laymen, thus easy to understand, it is penetrating and brilliant as well. Illuminations of age-old religious questions from a pragmatic perspective, written in a luminous style.

Although the metaphysics of words remains a relatively understudied domain, one of the more discussed topics has been the question of how to account for the apparent sameness of words. Put one way, the question concerns what it is that makes two word- instances (or tokens) instances of the same word. In this paper, I argue that the existing solutions to the problems all fail as they take the problem of sameness of word to be a problem about how one (...) object relates to another. I propose an alternative solution to the problem of sameness of word which is instead focused on the intrinsic nature of the properties possessed by words. The result is a more thoroughgoing version of nominalism than is currently defended in the literature. (Published Open Access). (shrink)

In this paper, I argue that the performance stories in the Zhuangzi, and the Butcher Ding story, emphasize an activity meditation practice that places the performer in a mindfulness flow zone, leading to graceful, efficacious, selfless, spontaneous, and free action. These stories are metaphors showing the reader how to attain a meditative state of focused awareness while acting freely in a flow experience. From my perspective, these metaphors are not about developing practical or technical skills per se. My argument challenges (...) a strict instrumental reading. Although instrumental reasoning can easily lead one to focus on the pragmatic outcomes depicted in these stories (See Eno, “Cook Ding’s Dao;” Callahan, “Cook Ding’s Life;” and Robins, “Beyond Skill”), the proposed pragmatic outcomes are merely a kind of collateral result of effortless, free actions, in the flow experience. The metaphors of Butcher Ding, the Lüliang rapids swimmer, the Wheelwright Bian, the Woodcarver Qing, the cicada catcher, the naked artist and so on are used to show the reader a way to engage in free and graceful action in the flow experience. Zhuangzi is not concerned about developing labour skills. He criticizes such skills; seen below when the Butcher claims to have “… left skill behind …” (進乎技矣) (Graham, Chuang-tzu, 63), and chapter five notes that “… skill is a peddler” (工為商) (Watson, Complete, 75).

James Lovelock, creator of the Gaia hypothesis and the greatest environmental thinker of our time, has produced an astounding new theory about future of life on Earth. He argues that the anthropocene the age in which humans acquired planetary-scale technologies - is, after 300 years, coming to an end. A new age, the novacene has already begun. New beings will emerge from existing artificial intelligence systems. They will think 10,000 times faster than we do and they will regard us (...) as we now regard plants as desperately slow acting and thinking creatures. But this will not be the cruel, violent machine takeover of the planet imagined by sci-fi writers and film-makers. These hyper-intelligent beings will be as dependent on the health of the planet as we are. They will need the planetary cooling system of Gaia to defend them from the increasing heat of the sun as much as we do. And Gaia depends on organic life. We will be partners in this project. It is crucial, Lovelock argues, that the intelligence of Earth survives and prospers. He does not think there are intelligent aliens, so we are the only beings capable of understanding the cosmos. Maybe, he speculates, the novacene could even be the beginning of a process that will finally lead to intelligence suffusing the entire cosmos. At the age 100, James Lovelock has produced the most important and compelling work of his life. (shrink)

Aesthetic testimony is testimony about aesthetic properties. For example, in aone straightforward case, one person might tell another that something is beautiful. Philosophical discussion about aesthetic testimony centers on the question of whether there are any important differences between aesthetic testimony and testimony about non-aesthetic descriptive matters. In particular, the focus is often on the respective epistemic credentials of aesthetic and non-aesthetic testimony relative to firsthand judgments in the respective domains. Most are inclined to think that in some way and (...) to some degree we typically treat aesthetic testimony as being epistemically inferior to testimony about non-aesthetic matters. Assuming an asymmetry in the way we typically treat aesthetic and non-aesthetic testimony, the philosophical debate then asks a number of questions. Is aesthetic testimony actually epistemically inferior? If so, in what ways, and what explains its inferiority? If not, why do our ordinary ways of thinking, talking, and engaging with aesthetic testimony treat it as being inferior? In this chapter, I consider various ways in which experimental philosophy can contribute to these debates. Drawing on extant work and some new empirical studies, this chapter provides an overview of what experimental philosophy has told us so far, and summarizes the implications for philosophical debate.

In this paper, I discuss how to distinguish between ontological categories and ordinary categories. Using an argument against van Inwagen’s proposed account of what makes a category ontological as a springboard, I argue that if ontological categories are modally robust, then ontological categories need to be understood hyperintensionally. This conclusion opens up a wide range of new ways to define ‘ontological category’, and I close by briefly outlining one such way in order to illustrate the advantages of embracing hyperintensionality in (...) this debate.

I then argue that Joseph Raz's influential Service Conception of Authority is unable to solve them.

I argue that this account has the resources to solve these (...) problems. (shrink)

Abstract:In my response to the commentators, I agree with Rosa Mayorga that Duns Scotus should be included as an important influence on Peirce's notion of agency, as well as his sense of the highest good. I explain, however, how Peirce's triadic view of agency is an improvement that relates to current debates between moral internalism and externalism. In response to Diana Heney, I defend Peirce's notion of evolutionary love as a form of intergenerational altruism, necessary to any community of inquiry. (...) I also argue, in response to her query, that Peirce did not subscribe to moral perfectionism. Instead, there is good reasons to think that he was a meliorist in Dewey's sense. The end is improvement, which seems to be an endless process, rather than the movement towards a static end. I agree with Aaron Wilson's claim that the pragmatic definition of truth implies the convergence theory of truth. However, I explain how the convergence theory of truth might be elaborated as to apply to ethical claims. I also discuss how the 'would be' of the convergence theory of truth is a problematic measure of moral claims. Like progress in science, it is better to measure a moral norm in terms of its improvement from previous ones. I take issue with Wilson's account of moral reality and his claim that truth can be attained by individuals in the absence of community. I end by arguing that reasonableness has to be understood as a process rather than a perfected state. (shrink)

This article uses the case of “social impact bonds” (SIBs) to explore the role of social science methods in new markets in “social investment.” Pioneered in the UK in 2010, SIBs use private capital to fund social programs with governments paying returns for successful outcomes. Central to the SIB model is the question of evaluation and the method to be used in determining program outcomes and investor returns. In the United States, the randomized controlled trial (RCT) has been the dominant (...) method. However, this has not been without controversy. Some SIB practitioners and investors have argued that, while this may be the perfect tool, the need to grow the SIB market demands a more pragmatic approach. Drawing from a three-year study of SIBs, and informed by Science and Technology Studies (STS)-inspired work on valuation and the social life of methods, the article explores RCTs as both a valuation technology central to SIB design and the object of a micropolitics of valuation which has impeded market growth. It is the relationship between, and the politics of, evaluation and valuation that is a key lesson of the SIB experiment and an important insight for future research on “social investment” and other settings where methods are constitutive of financial value.

In nine lively essays, bioethicist J. David Velleman challenges the prevailing consensus about assisted suicide and reproductive technology, articulating an original approach to the ethics of creating and ending human lives. He argues that assistance in dying is appropriate only at the point where talk of suicide is not, and he raises moral objections to anonymous donor conception. In their place, Velleman champions a morality of valuing personhood over happiness in making end-of-life decisions, and respecting the personhood of future children (...) in making decisions about procreation. These controversial views are defended with philosophical rigor while remaining accessible to the general reader. Written over Velleman's 30 years of undergraduate teaching in bioethics, the essays have never before been collected and made available to a non-academic audience. They will open new lines of debate on issues of intense public interest."--Publisher's website. (shrink)

This is the first book-length treatment of Critical Buddhism as both a philosophical and religious movement, where the lines between scholarship and practice blur. Providing a critical and constructive analysis of Critical Buddhism, particularly the epistemological categories of critica and topica, this book examines contemporary theories of knowledge and ethics in order to situate Critical Buddhism within modern Japanese and Buddhist thought as well as in relation to current trends in contemporary Western thought.

In Sensations of History, James J. Hodge argues that animation in new media art transforms historical experience in the digital age. Combining close textual analysis of experimental new media artworks with discussion of key phenomenological texts, Sensations of History argues for the broad critical significance of animation as we shift from analog to digital technologies. Hodge looks closely at animation aesthetics, which allow for a clear grasp of the ways digital technologies transform our sense of historical experience.

One objection to conventional AI ethics is that it slows innovation. This presentation responds by reconfiguring ethics as an innovation accelerator. The critical elements develop from a contrast between Stability AI’s Diffusion and OpenAI’s Dall-E. By analyzing the divergent values underlying their opposed strategies for development and deployment, five conceptions are identified as common to acceleration ethics. Uncertainty is understood as positive and encouraging, rather than discouraging. Innovation is conceived as intrinsically valuable, instead of worthwhile only as mediated by social (...) effects. AI problems are solved by more AI, not less. Permissions and restrictions governing AI emerge from a decentralized process, instead of a unified authority. The work of ethics is embedded in AI development and application, instead of functioning from outside. Together, these attitudes and practices remake ethics as provoking rather than restraining artificial intelligence. (shrink)

What is involved in having a singular thought about an ordinary object? On the leading epistemic view, one has this capacity if and only if one has belief-forming dispositions which would reliably enable one to get its properties right (Dickie, 2015). I first argue that Dickie’s official view entails surprising and unpalatable claims about either rationality or singular thought, before offering a precisification. Once we have reached that level of abstraction, it becomes difficult to see what is distinctively epistemic about (...) the framework. If we are to tease out the delicate connection between singular thought and knowledge, we should suspend the assumption that there is a homogeneous core, present in all cases of such thought, and that it is from there that its (univocal) epistemic character derives.

Durkheim and National Identity in Ireland uses the classical sociology of Durkheim, in association with established theories of nation formation, to explore the development of opposed national identities in Ireland and Northern Ireland. James Dingley looks at Catholicism, the core of Irish nationalist identity, and draws upon its established sociological association of pre-industrial, rural peasant society and culture. By contrast, Dingley reviews Protestantism as the core of Ulster identity, with the equal association of industrial, scientific society, as the key (...) elements in explaining why Ulster Unionists evolved an opposed and incompatible culture and identity to Irish nationalism. These underlying religious philosophies of Catholicism and Protestantism illustrate how religion acted as a symbolic representation of socio-economic separate development, and examine a Durkheimian analysis as an alternative approach to conflict resolution in Northern Ireland.

In the seminal Just and Unjust Wars, Michael Walzer famously considered the ethics of modern warfare, examining the moral issues that arise before, during, and after conflict. However, Walzer and subsequent scholars have often limited their analyses of the ethics of combat to soldiers on the ground and failed to recognize the moral responsibilities of senior political and military leaders. In Just War Reconsidered: Strategy, Ethics, and Theory, James M. Dubik draws on years of research as well as his (...) own experiences as a soldier and teacher to fill the gaps left by other theorists. He applies moral philosophy, political philosophy, and strategic studies to historical and contemporary case studies to reveal the inaccuracies and moral bankruptcy that inform some of the literature on military ethics. Conventional just war theory adopts a binary approach, wherein political leaders have moral accountability for the decision to go to war and soldiers have accountability for fighting the war ethically. Dubik argues, however, that political and military leadership should be held accountable for the planning and execution of war in addition to the decision to initiate conflict. Dubik bases his sober reassessment on the fundamental truth that war risks the lives of soldiers and innocents as well as the political and social health of communities. He offers new standards to evaluate the ethics of warfare in the hope of increasing the probability that the lives of soldiers will not be used in vain and the innocent not put at risk unnecessarily."--Provided by publisher.

What role does ethics play in modern-day warfare? Is it possible for ethics and militarism to exist hand-in-hand? James Eastwood examines the Israeli military and its claim to be "the most moral army in the world." This claim has been strongly contested by human rights bodies and international institutions in their analysis of recent military engagements in the West Bank, Gaza, and Lebanon. Yet at the same time, many in Israel believe this claim: including the general public, military personnel, (...) and politicians. Compiled from extensive research including interviews with soldiers, Eastwood unpacks the ethical pedagogy of the Israeli military, as well as soldier-led activism which voices a moral critique, and argues that the belief in moral warfare does not exist separately from the growing violence of Israel's occupation. This book is ideal for those interested in military ethics and Israeli politics, and provides crucial in-depth analysis for students and researchers alike. It examines theories of morality and ethics in war through a comprehensive study of the Israel Defence Forces. It will appeal to researchers and students exploring military ethics and Israeli politics, international relations, as well as those studying war and politics in the wider Middle East. It also examines theories of morality and ethics in war through a comprehensive study of the Israel Defence Forces. (shrink)

Following his successful Who's Afraid of Postmodernism? leading Christian philosopher James K. A. Smith introduces the philosophical sources behind postliberal theology. Offering a provocative analysis of relativism, Smith provides an introduction to the key voices of pragmatism: Ludwig Wittgenstein, Richard Rorty, and Robert Brandom. Many Christians view relativism as the antithesis of absolute truth and take it to be the antithesis of the gospel. Smith argues that this reaction is a symptom of a deeper theological problem: an inability to (...) honor the contingency and dependence of our creaturehood. Appreciating our created finitude as the condition under which we know (and were made to know) should compel us to appreciate the contingency of our knowledge without sliding into arbitrariness. Saying "It depends" is not the equivalent of saying "It's not true" or "I don't know." It is simply to recognize the conditions of our knowledge as finite, created, social beings. Pragmatism, says Smith, helps us recover a fundamental Christian appreciation of the contingency of creaturehood. This addition to an acclaimed series engages key thinkers in modern philosophy with a view to ministry and addresses the challenge of relativism in a creative, original way. (shrink)

Philosophical reflection on the conditions of knowledge did not begin in a cultural vacuum. Several centuries before the Ionian thinkers began their investigations, the Homeric bards had identified various factors that militate against a secure grasp of the truth. In the words of the ‘second invocation of the Muses’ in Iliad II: “you, goddesses, are present and know all things, whereas we mortals hear only a rumor and know nothing.” Similarly Archilochus: “Of such a sort, Glaucus, son of Leptines, is (...) the mind of mortal man, whatever Zeus may bring him for the day, for he thinks such things as he meets with.” When one adds the truism that the scope of human experience pales in comparison with the synoptic view of events enjoyed by the gods, it follows that for most matters it is for the gods to know and mortals merely to conjecture. Traces of the older ‘poetic pessimism’ can be seen in the teachings of many of the first philosophers. Alcmaeon reaffirms that “while the gods enjoy clear and certain knowledge of all things, mortals must conjecture from signs” (B 1). Although Xenophanes encourages inquiry into a wide range of phenomena, he concludes that “No man has known nor will there be anyone who knows the clear and sure truth concerning the gods and what I say about all things” (B 34). And when philosophers begin to affirm a more optimistic view they often do so in terms that invite comparison with the older outlook. The chief truth Heraclitus claims to have discovered is the logos or ‘basic formula’ which holds everywhere and forever (B 1, 30, 80, and 90). Parmenides provides reason to think that human beings can discover the truth even about things located “far off” (B 4). And both Empedocles and Democritus contrast the inferior awareness of those “who think in terms of what they have met with” with the wisdom available to those who have heard and ponder their teachings (B 131). For these thinkers, separation in space and time—the old ‘locality problem’—no longer posed an impediment to knowledge. -/- . (shrink)

The Lotus Sūtra is a devotional text rather than a philosophical one – i.e., it seems intended to work on the level of the emotions and the senses rather than the intellect. And yet, despite its other‐worldly aspects, the Lotus Sūtra has been employed over the centuries as a political text, both as a tool for maintaining the status quo and especially in the twentieth century but with a few historical precedents as an inspiration and justification for political transformation or (...) reform. This chapter explores some of the various ways in which the Lotus Sūtra has been understood and utilized as a political text. The Lotus Sūtra serves as the primary scripture for two important East Asian Buddhist sects: the sixthcentury Tiantai sect, often called the first indigenous Chinese Buddhist school, and the twelfth‐century Nichiren sect, which makes a similar claim to being the first indigenous Japanese Buddhist sect.

This book examines the relationship between Ubuntu and the idea of personhood. Ubuntu in its broadest sense is rooted in the belief that the full development of personhood comes with shared identity and the idea that an individual's humanity is fostered in a network of relationships: I am because you are; we are because you are. The chapters in this book seek to interrogate this relational quality of personhood embodied in Ubuntu. The book further seeks to examine whether we can (...) talk about relational personhood without running the risk of essentialism. It argues that no human society is possible without a network of relations, which involves, among other elements, communication and interaction between individuals. It is a critical engagement with how Ubuntu shapes those ethical values of connectedness and interdependence within society. The book also asks whether we can find relevance in Ubuntu as an ethical value system, which is likely to mediate our daily activities and the social institutions, which serve communities in post-colonial societies.

The nectar is in the journey, |3dotnld| ultimate goals may be illusory, nay, most likely are but a gossamer wing. Day by day, however, human life triumphs in its ineluctable capacity to hang in and make things better. Not perfect, simply better." John McDermott, Streams of Experience I investigate one manner in which classical American pragmatism might be utilized by theorists and practitioners interested in addressing urban environmental problems. Despite the widespread adoption of the sustainability moniker within the environmental movement, (...) evidence suggests that progress toward implementing urban environmental sustain ability proposals has been minimal. To address this inaction, I undertake an analysis of the philosophy of progress guiding efforts to transition urban environments toward sustainability. I argue that one of the reasons so little has been accomplished in terms of implementing existing urban environmental sustainability proposals is that a disproportionate emphasis has been placed on values that stem from economic-centered indicators of progress. I argue that the value of progress ought to be less about how much of a certain type of economic growth sustainability proposals ultimately can generate for urban environments and more about ensuring that continual incremental societal progress takes place.

Over half of the world's population (3 billon people) now lives in urban environments. The combination of people, industry, and commerce enmeshed in environments over-determined by plans, designs, and configurations that continue to emphasize ease, efficiency, and spatial sprawl over ecological constraints and sustainability help to make urban environments the primary contributors to multiple types of ecological degradation. With this in mind, urban environments demand greater sustained theoretical and practical attention than has been and is the norm under status quo (...) approaches to urbanism that pay little regard to ecological constraints and under traditional models of environmentalism informed by an anti-urban bias. Fortunately, an emerging form of urban environmentalism exists that recognizes the central ecological role of urban environments. This emerging form of urban environmentalism also recognizes urban environments to be the places where environmental problems are often most severe and where environmental solutions are in most need of immediate implementation. The upshot of this dual recognition is that it is accompanied by a growing dual awareness of urban environmental problems and solutions. In this paper I argue that despite this dual recognition and awareness, a paradoxical form of inaction is the norm when it comes to implementing urban environmental solutions. I explain why this is the case by outlining what I call the paradox of urban environmentalism. I explain why the paradox should be considered one of the most significant problems of this new environmental century as well as that frame which opens the door to a new sense of what is possible in urban environments. In the process of considering what is possible, I arrive at some preliminary conclusions about a possible methodological role philosophers can play in helping to address this paradoxical inaction in the hopes of bringing about more sustainable urban environments.

BackgroundThe evolution of the female orgasm in humans and its role in romantic relationships is poorly understood. Whereas the male orgasm is inherently linked to reproduction, the female orgasm is not linked to obvious reproductive or survival benefits. It also occurs less consistently during penetrative sex than does the male orgasm. Mate-choice hypotheses posit that the wide variation in female orgasm frequency reflects a discriminatory mechanism designed to select high-quality mates.ObjectiveWe aimed to determine whether women report that their orgasm frequency (...) varies between partners, whether this variation reflects mates' personal characteristics, and whether this variation reflects own and partner sexual behaviour during intercourse.DesignWe collected survey data from 103 women who rated the extent to which their orgasm frequency varied between partners, the characteristics of previous sexual partners who induced high-orgasm frequency and those who induced low-orgasm frequency,...
