In this article I argue that the Farm Security Administration (FSA) photographs of the Greenbelt Town program in the late 1930s function beyond the goals for which the FSA photographs are typically known.1 The FSA photographs documented scenes of urban and rural poverty during the Great Depression to make the case for supporting President Franklin D. Roosevelt’s New Deal policies. In the midst of the Great Depression, the U.S. government planned and built three Greenbelt towns with a utopian vision of (...) modern living for displaced farmers and the urban poor. I argue that within the larger collection of FSA photographs, which typically portray images of American struggle and resilience, exists a group of photographs .. (shrink)

Problem one: why, if God designed the human mind, did it take so long for humans to develop theistic concepts and beliefs? Problem two: why would God use evolution to design the living world when the discovery of evolution would predictably contribute to so much nonbelief in God? Darwin was aware of such questions but failed to see their evidential significance for theism. This paper explores this significance. Problem one introduces something I call natural nonbelief, which is significant because it (...) parallels and corroborates well-known worries about natural evil. Problems one and two, especially when combined, support naturalism over theism, intensify the problem of divine hiddenness, challenge Alvin Plantinga’s views about the naturalness of theism, and advance the discussion about whether the conflict between science and religion is genuine or superficial.

Research into the roots of ideological extremism has traditionally focused on the social, economic, and demographic factors that make people vulnerable to adopting hostile attitudes toward outgroups. However, there is insufficient empirical work on individual differences in implicit cognition and information processing styles that amplify an individual’s susceptibility to endorsing violence to protect an ideological cause or group. Here we present original evidence that objectively assessed cognitive inflexibility predicts extremist attitudes, including a willingness to harm others, and sacrifice one’s life (...) for the group. Across two samples (N = 1,047) from the United Kingdom and United States, structural equation models demonstrated that cognitive inflexibility predicted endorsement of violence to protect the national ingroup, which in turn predicted a willingness to die for the group. These statistical models accounted for an average of 31.4% of the variance in willingness to die for the group, after accounting for demographic variables. Furthermore, cognitive inflexibility was related to greater confidence in the decision to sacrifice one’s life in an ingroup trolley problem scenario. Analysis of participants’ performance on the cognitive tasks revealed that cognitive rigidity – distinctly from other aspects of cognition – was specifically implicated as a cognitive antecedent of extremist attitudes. Implications for the study of radicalization and identity fusion throug... (shrink)

Some philosophers have argued for what I call the reason-giving requirement for conscientious refusal in reproductive healthcare. According to this requirement, healthcare practitioners who conscientiously object to administering standard forms of treatment must have arguments to back up their conscience, arguments that are purely public in character. I argue that such a requirement, though attractive in some ways, faces an overlooked epistemic problem: it is either too easy or too difficult to satisfy in standard cases. I close by briefly considering (...) whether a version of the reason-giving requirement can be salvaged despite this important difficulty. (shrink)

While defining martial arts is not prerequisite to philosophizing about them, such a definition is desirable, helping us resolve disputes about the status of hard cases. At one extreme, Martínková and Parry argue that martial arts are distinguished from both close combat (as unsystematic) and combat sports (as competitive), and from warrior arts (as lethal) and martial paths (as spiritual). At the other extreme, mixed martial arts pundits and Bruce Lee speak of combat sports generally as martial arts. I argue (...) that the fine-grained taxonomy proposed by Martínková and Parry can be usefully supplemented by a broader definition, specifically the following: martial arts are systematic fighting styles and practices as ways of embodying wisdom. A possible difficulty here is that such views face the charge of overemphasizing the “philosophical” aspect of martial arts. My definition can, however, avoid this apparent problem. If martial arts essentially aim to embody wisdom, this applies no less to the (strategic) practical wisdom of The Art of War than to the (ethical) practical wisdom of the Tao Te Ching. In an extended sense, then, any systematic fighting style, including combat sports, may count as a martial art insofar as it embodies wisdom by improving practical fighting skills. (shrink)

Recent work in the psychology of happiness has led some to conclude that we are unreliable assessors of our lives and that skepticism about whether we are happy is a genuine possibility worth taking very seriously. I argue that such claims, if true, have worrisome implications for procreation. In particular, they show that skepticism about whether many if not most people are well positioned to create persons is a genuine possibility worth taking very seriously. This skeptical worry should not be (...) confused with a related but much stronger version of the argument, which says that all human lives are very bad and not worth starting. I criticize the latter stance, but take seriously the former stance and hope it can be answered in future work. (shrink)

Alongside a revival of interest in Thomism in philosophy, scholars have realised its relevance when addressing certain contemporary issues in bioethics. This book offers a rigorous interpretation of Aquinas's metaphysics and ethical thought, and highlights its significance to questions in bioethics. Jason T. Eberl applies Aquinas’s views on the seminal topics of human nature and morality to key questions in bioethics at the margins of human life – questions which are currently contested in the academia, politics and the media (...) such as: When does a human person’s life begin? How should we define and clinically determine a person’s death? Is abortion ever morally permissible? How should we resolve the conflict between the potential benefits of embryonic stem cell research and the lives of human embryos? Does cloning involve a misuse of human ingenuity and technology? What forms of treatment are appropriate for irreversibly comatose patients? How should we care for patients who experience unbearable suffering as they approach the end of life? _Thomistic Principles and Bioethics_ presents a significant philosophical viewpoint which will motivate further dialogue amongst religious and secular arenas of inquiry concerning such complex issues of both individual and public concern.

Videogames present deep challenges for traditional concepts of sport and games. Cybersport in particular suggests that sport might be transposed into digital arenas, and videogames in general provide apparently striking counterexamples to the orthodox Suitsian theory of games, seeming to lack strictly prelusory goals and perhaps even also constitutive rules. I argue as follows: if any cybersports count as genuine sports, it will be those most closely resembling uncontroversial core instances of sport, those that essentially involve gross motor skill. Even (...) so, we might reject cybersports as sport by distinguishing physical skills’ domain of execution from their domain of application, sport implying the non-virtual status of both. Although, like chess, videogames appear to lack prelusory goals, chess conventions and nominal descriptions of the object of any videogame suggest the possibility of Suitsian compliance, as does the inclusion of ‘cheat codes’ in videogame programming. Perhaps such... (shrink)

The questions of whether there is a shared nature common to all human beings and, if so, what essential qualities define this nature are among the most widely discussed topics in the history of philosophy and remain the subject of perennial interest and controversy. This book offers a metaphysical investigation of the composition of the human essence-that is, with what is a human being identical or what types of parts are necessary for a human being to exist: an immaterial mind, (...) a physical body, a functioning brain, a soul? It also considers the criterion of identity for a human being across time and change-that is, what is required for a human being to continue existing as a person despite undergoing physical and psychological changes over time? Jason Eberl's investigation presents and defends a theoretical perspective from the thirteenth-century philosopher and theologian Thomas Aquinas. Advancing beyond descriptive historical analysis, this book places Aquinas's account of human nature into direct comparison with several prominent contemporary theories: substance dualism, emergentism, animalism, constitutionalism, four-dimensionalism, and embodied mind theory. There are practical implications of exploring these theories as they inform various conclusions regarding when human beings first come into existence-at conception, during gestation, or after birth-and how we ought to define death for human beings. Finally, each of these viewpoints offers a distinctive rationale as to whether, and if so how, human beings may survive death. This book's central argument is that the Thomistic account of human nature includes several desirable features that other theories lack and offers a cohesive portrait of one's continued existence from conception through life to death and beyond.

Whistle blowing programs have been central to numerous government, legislative, and regulatory reform efforts in recent years. To protect investors, corporate boards have instituted numerous measures to promote whistle blowing. Despite significant whistle blowing incentives, few individuals blow the whistle when presented with the opportunity. Instead, individuals often remain fallaciously silent and, in essence, become passive fraudsters themselves. Using the fraud triangle and models of moral behavior, we model and analyze fallacious silence and identify factors that may motivate an individual (...) to rationalize fallacious silence. We use a survey of graduate accounting students to test hypothesized factors that contribute to fallacious silence rationalizations in an academic setting. We find evidence that the ability to rationalize fallacious silence is related to community influences and personal traits such as awareness and moral competence. (shrink)

The process of engaging in historical empathy holds the potential for significant curricular and dispositional benefits for students in history classrooms. In order to realize these benefits, classroom teachers must be able to integrate historical empathy into their existing planning and teaching; a process that would benefit from empirical examination. This single subject case study examined the pedagogical reasoning process of an experienced classroom teacher who integrated historical empathy into an existing instructional unit designed to foster student knowledge of social (...) control as an enduring historical understanding. The findings of this study suggest that experienced teachers may only be able to partially anticipate the unique pedagogical needs integrating historical empathy requires, and that a holistic examination of pedagogical reasoning during all phases of planning and teaching may be most suitable for the task.

Sport aesthetics is an important but often marginalized field in the philosophy of sport. Kinetic Beauty offers a comprehensive, principled, pluralist introduction to the philosophical aesthetics of sport. The book tackles a wide variety of issues in the philosophical aesthetics of sport, proposing a five-level analysis that coordinates extant scholarship on the same conceptual map, reveals gaps in the literature, and motivates a fresh perspective on stubborn debates and novel topics in the field. This is an excellent resource for professors (...) and students in the philosophy of sport, sport aesthetics, general aesthetics, and the philosophy of art. It is also a fascinating read for those working in kinesiology, sport studies, philosophy, art, and aesthetics. (shrink)

In this century a number of events could extinguish humanity. The probability of these events may be very low, but the expected value of preventing them could be high, as it represents the value of all future human lives. We review the challenges to studying human extinction risks and, by way of example, estimate the cost effectiveness of preventing extinction-level asteroid impacts.

The challenge from religious diversity is widely thought to be one of the most important challenges facing religious belief. Despite this consensus, however, many epistemologists think that standard versions of the challenge fail because they threaten to implicate many seemingly reasonable yet highly controversial non-religious beliefs. In light of this we develop an alternative, less discussed, diversity challenge that does not generalize. This challenge concerns why so much religious diversity exists in the first place given common religious, and in particular (...) theistic, views. Although there are some interesting scientific explanations of such diversity, satisfying theistic explanations of its existence are still required. (shrink)

Many people think that the amount of evil and suffering we observe provides important and perhaps decisive evidence against the claim that a loving God created our world. Yet almost nobody worries about the ethics of human procreation. Can these attitudes be consistently maintained? This chapter argues that the most obvious attempts to justify a positive answer fail. The upshot is not that procreation is impermissible, but rather that we should either revise our beliefs about the severity of global arguments (...) from evil or develop new and better defenses of human procreation. Although both possibilities are worthy of pursuit, this chapter focuses on the latter possibility. (shrink)

In his article entitled 'Divine hiddenness and the demographics of theism' ("Religious Studies", 42 (2006), 177–191), Stephen Maitzen draws our attention to an important feature that is often overlooked in discussion about the argument from divine hiddenness (ADH). His claim is that an uneven distribution of theistic belief (and not just the mere existence of non-belief) provides an atheological challenge that cannot likely be overcome. After describing what I take to be the most pressing feature of the problem, I argue (...) that a hidden premise causes Maitzen to overlook a Molinist solution. The upshot is a softening of the atheological import of the demographic data. (shrink)

Our decision-making is often subject to framing effects: alternative but equally informative descriptions of the same options elicit different choices. When a decision-maker is vulnerable to framing, she may consent under one description of the act, which suggests that she has waived her right, yet be disposed to dissent under an equally informative description of the act, which suggests that she has not waived her right. I argue that in such a case the decision-maker’s consent is simply irrelevant to the (...) permissibility of proceeding. I then consider two alternative views. According to the first, people susceptible to framing are able to give valid consent so long as they are sufficiently informed. This suggestion, I argue, maintains an overly narrow focus on mere quantity of information to the exclusion of other choice-affecting factors. A second response, which appeals to hypothetical consent, is likewise of little use in resolving the moral problem posed by framing effects. I conclude that if susceptibility to framing undermines the validity of consent, we may have good reason to reconsider whether consent has the rights-waiving function commonly attributed to it.

Ever since its discovery nearly thirty years ago, the phenomenon of blindsight — vision without visual consciousness — has been the source of great controversy in the philosophy of mind, psychology, and the neurosciences. Despite the fact that blindsight is widely acknowledged to be a critical test-case for theories of mind, Blindsight and the Nature of Consciousness is the first extended treatment of the phenomenon from a philosophical perspective. Holt argues, against much received wisdom, for a thorough-going materialism — the (...) view not only that mental states are brain states, but (much more controversially) that mental properties are physical as well. Designed not only for philosophers and scientists, Blindsight and the Nature of Consciousness has something to say to anyone interested in the mystery of the human mind and in how philosophers and scientists are working toward solving that mystery.

Though animal ethics in sport obviously applies most urgently to cases of animals at mortal risk (e.g., hunting and bullfighting) or vulnerable to various types of abuse (e.g., doping and harmful training practices), less obvious domains bear scrutiny as well. Here I examine whether we can strictly take not just riders but horses to be players in equine sports. There is an apparent tension in the concept of equestrian prowess, a peculiar blend of skills and attitudes, between regarding horses as (...) subjects of persuasion or collaboration and treating them as objects of control. As our understanding of animal cognition and behaviour continues to improve, it becomes increasingly clear that animal intelligence and agential capacities are far greater than we formerly presumed. In this light, using Suits’s theory of games, I argue that horses are game players that sometimes consent (or assent) and sometimes refuse to play equine sports. Drawing on recent accounts of horse-rider partnership and on my own equestrian background, I conclude by sketching a utopian vision of what equine sports could be. (shrink)

This paper develops the outlines of a pragmatic, adaptive management-based approach toward the control of invasive nonnative species (INS) through a case study of Kings Bay/crystal River, a large artesian springs ecosystem that is one of Florida’s most important habitats for endangered West Indian manatees (Trichechus manatus). Building upon recent critiques of invasion biology, principles of adaptive management, and our own interview and participant–observer research, we argue that this case study represents an example in which rigid application of invasion biology’s (...) a␣priori imperative to minimize INS has produced counterproductive results from both an ecological and social standpoint. As such, we recommend that INS control in Kings Bay should be relaxed in conjunction with an overall program of adaptive ecosystem management that includes meaningful participation and input from non-institutional stakeholders. However, we also note that adaptive management and INS control are by no means mutually exclusive, in Kings Bay or elsewhere. Instead, we suggest that adaptive management offers a means by which INS control efforts can emerge from—and be evaluated through—ongoing scientific research and participatory dialogue about the condition of specific places, rather than non-contextual assumptions about the harmfulness of INS as a general class.

Our motor system can generate representations which carry information about the goals of another agent's actions. However, it is not known whether motor representations play a deeper role in social understanding, and, in particular, whether they enable tracking others' beliefs. Here we show that, for adult observers, reliably manifesting an ability to track another's false belief critically depends on representing the agent's potential actions motorically. One signature of motor representations is that they can be disrupted by constraints on an observed (...) agent's action capacities. We therefore used a `mummification' technique to manipulate whether the agent in a visual ball-detection task was free to act or whether he was visibly constrained from acting. Adults' reaction times reliably reflected the agent's beliefs only when the agent was free to act on the ball and not when the agent was visibly constrained from acting. Furthermore, it was the agent's constrained action capabilities, rather than any perceptual novelty, that determined whether adult observers' reaction times reliably reflected the agent's beliefs. These findings signal that our motor system may underpin more of social cognition than previously imagined, and, in particular, that motor representations may underpin automatic false-belief tracking.

Most deontologists claim that it is more objectionable to do harm than it is to allow harm of comparable magnitude. I argue that this view faces a largely neglected puzzle regarding the moral relevance of an agent's past behavior. Consider an agent who chooses to save five people rather than one, where the one person's life is in jeopardy because of something the agent did earlier. How are the agent's obligations affected by the fact that his now letting the one (...) die would retroactively make it the case that he has killed? I argue that the most promising deontological responses to this question are difficult to defend. Further, it is unclear how the deontologist can resolve a further set of cases, in which commonsense intuition indicates that an agent is required to terminate a threat she initiated more recently in preference to a threat she initiated less recently.

According to the causal theory of parenthood, people incur parental obligations by causing children to exist. Proponents of the causal theory often argue that gamete donors have special obligations to their genetic offspring. In response, many defenders of current gamete donation practices would reject the causal theory. In particular, they may invoke the ‘too many parents problem’: many people who causally contribute to the existence of children – for instance, fertility doctors – do not thereby incur parental obligations. This article (...) argues that the conclusions commonly drawn by causal theorists, and by their critics, are premature. Causal theorists have a promising response to the too many parents problem. This response, however, defuses the moral concern that many causal theorists have raised about gamete donation. A similar point, it is argued, applies to Rivka Weinberg’s ‘Hazmat Theory’. -/- .

This chapter examines a common objection to the philosophy of religion, namely, that it has not sufficiently embraced the injunction of Socrates to follow the argument where it leads. Although a general version of this charge is unfair, one emerging view in the field, which I call religious Mooreanism, nonetheless risks running contrary to the Socratic injunction. According to this view, many people can quickly, easily, and reasonably deflect all known philosophical challenges to their core religious outlooks, including arguments from (...) evil. This chapter argues that, in addition to being in tension with the Socratic injunction, religious Mooreanism is less plausible than traditional Mooreanism and in any case has not been adequately defended.

During the 1970s and 1980s, political psychologists at the State University of New York at Stony Brook focused political scientists’ attention on online processing. Borrowing from the new field of social cognition in psychology, they argued that voters’ evaluations of candidates are the products of a summing up of reactions to happenings during a campaign. Voters might not remember the specific events later on, but their running tallies of reactions over the duration of the campaign would ensure that they take (...) the forgotten information into account when entering the voting booth. Later, these same scholars yet again borrowed from (a very changed) psychology, and argued that many people, especially the most politically sophisticated, try to confirm their current political evaluations—for example, by seeking out confirmatory evidence and dismissing evidence that challenges their attitudes. We ask whether online processing and motivated reasoning have the same or different implications for democratic governance, and whether the two empirical perspectives can be reconciled. (shrink)

Blindsight is a hot topic in philosophy, especially in discussions of consciousness. Here I critically examine various attempts to bring blindsight to bear on debates about qualia -- the raw constituents of consciousness. I argue that blindsight does not unequivocally support any particular theory of qualia. It does, however, vindicate the view that there are qualia, despite arguments -- most notably by Daniel Dennett -- to the contrary.

The essay examines the ancient Greek origin of philosophy relative to the concept of wisdom. The nature of the sage is first considered. The sage is one who is deemed wise in his or her performances. But what is ‘wise’ about such performances? The Socratic denial of sage status is considered in reference to this. Socrates concludes that he is not wise as the gods are wise, but that he is wise insofar as he knows that he is not wise. (...) The apparent contradiction is resolved through the distinction between human (finite) and divine (infinite) wisdom. The latter notion is further examined in the works of Aristotle who articulates the “classical paradigm” of philosophy in pursuit of infinite wisdom. The attributes of infinite wisdom are identified, and the essay concludes with a discussion of the sagely performance of infinite wisdom, Aristotle himself serving as the representative example.

This study examined the performance and future predictions for the Middle East produced by 18 global climate models participating in the Intergovernmental Panel on Climate Change Fourth Assessment Report. Under the Special Report on Emission Scenarios A2 emissions scenario the models predict an overall temperature increase of ~1.4 K by mid-century, increasing to almost 4 K by late-century for the Middle East. In terms of precipitation the southernmost portion of the domain experiences a small increase in precipitation due to the (...) Northward movement of the Inter-Tropical Convergence Zone. The largest change however is a decrease in precipitation that occurs in an area covering the Eastern Mediterranean, Turkey, Syria, Northern Iraq, Northeastern Iran and the Caucasus caused by a decrease in storm track activity over the Eastern Mediterranean. Other changes likely to impact the region include a decrease of over 170,000 km 2 in viable rainfed agriculture land by late-century, increases in the length of the dry season that reduces the length of time that the rangelands can be grazed, and changes in the timing of the maximum precipitation in Northern Iran that will impact the growing season, forcing changes in cropping strategy or even crop types.

Following Kant, subjectivity is seen as an obstacle to any access into things themselves. For this reason, Kant concludes that metaphysics as the science of being as being is necessarily impossible. In this essay, the possibilities of metaphysics in light of the problem of subjectivity are reexamined. The nature of subjectivity and the subject’s encounter with being are analyzed yielding two fundamental relational structures that hold with respect to being and the subject. Further examination of the act of reflection coupled (...) with judgment reveals that these structures may in fact be transcended, from which an encounter with being as such follows. On the basis of reflection and judgment, metaphysics is in consequence determined to be possible. (shrink)

In his doctoral dissertation On the Principle of Sufficient Reason, Arthur Schopenhauer there outlines a critique of Euclidean geometry on the basis of the changing nature of mathematics, and hence of demonstration, as a result of Kantian idealism. According to Schopenhauer, Euclid treats geometry synthetically, proceeding from the simple to the complex, from the known to the unknown, “synthesizing” later proofs on the basis of earlier ones. Such a method, although proving the case logically, nevertheless fails to attain the raison (...) d’être of the entity. In order to obtain this, a separate method is required, which Schopenhauer refers to as “analysis,” thus echoing a method already in practice among the early Greek geometers, with however some significant differences. In this essay, I here discuss Schopenhauer’s criticism of synthesis in Euclid’s Elements, and the nature and relevance of his own method of analysis. (shrink)

The aim of this essay is to show that phenomenal properties are contentless modes of appearances of representational properties. The essay initiates with examination of the first-person perspective of the conscious observer according to which a “reference to I” with respect to the observation of experience is determined.

These modifications are then analyzed with respect to the content (...) of experience and from this the ground of the distinction between phenomenal and representational properties is identified.

This paper considers the trajectory of Althusser's Spinozism pre- and post-May ‘68. Where Althusser's application of Spinoza would often lead him into unknown or non-Marxist territory, one alternative way to think this relation is through the figure of Mao, whose concept of non-antagonistic contradiction I propose to read in terms of Spinoza's “determinate negation.” Although not going so far as to suggest that a certain combination of Mao and Spinoza would have enabled Althusser to “complete” Marx, this paper speculates on (...) this omission from his work and what positive insights we can draw from it retrospectively for developing Althusser's political philosophy.

The purist/partisan distinction has dominated recent discussions of sport spectatorship and sport aesthetics. The focus of such discussions, however, has been sport in general or, often implicitly, team sports in particular. Here, using mixed martial arts (MMA) as a case study, we argue that specific aspects of the sport in question can significantly affect how the purist/partisan distinction plays out for viewers. MMA’s status as an individual combat sport mitigates, in illuminating ways, the partisanship displayed so prominently among fans of (...) team sports. We also examine the role of external attitudes – in both the betting subculture of MMA and purist attitudes toward individual combat sports and martial arts – in shaping MMA spectatorship. (shrink)

De Neys's incisive critique of empirical and theoretical research on the exclusivity feature underscores the depth of the challenge of explaining the interplay of fast and slow processes.

Since Descartes, the nature of doubt has played a central role in the development of metaphysics both positively and negatively. Despite this fact, there has been very little discussion centering round the specific nature of doubt which led, for example, to the Cartesian discovery of the cogito. Certainly, the role of doubt has been well recognized: through doubt Descartes arrives at his indubitable first principle. But what can it mean to doubt the existence of the sensible world? This would seem (...) to rest upon the assumption that we have clear and distinct knowledge of the precise nature of what it means to exist and indeed of what it means to be. As it stands, Descartes’ initiates his Meditations upon certain definite assumptions that demand more thorough interrogation. In this paper and presentation, I examine the possible assumptions inherent in the Cartesian method of doubt within the first and second meditation and the manner in which this leads to the discovery of the cogito. I consider a number of essential questions in light of this: What presuppositions lie at bottom to Cartesian doubt? What is the precise nature of metaphysical doubt? What can it mean to doubt the existence of the sensible world? (shrink)
