BioShock Infinite follows the journey of Booker DeWitt, a reluctant detective from New York City who is transplanted via rowboat and lighthouse‐turned‐rocket to the city of Columbia. Booker is charged with the task of bringing back a girl in order to wipe away his debt. The girl, Elizabeth Comstock, has been locked in a tower since infancy by her father, Zachary Comstock, and is protected by a menacing Songbird. Although the game centers on Booker and his story, (...) this chapter focuses on Elizabeth, looking at her through a feminist lens. Freeing Elizabeth from her tower, one could argue, is in a way freeing her from oppression of men. If we take Elizabeth as her own person, rather than as a mere companion, does Elizabeth's freedom from tower mean real freedom for her? Does Booker treat Elizabeth any differently than Comstock does? And, what really is Elizabeth's role in Booker's drowning?. (shrink)

“Father” Zachary Hale Comstock is a self‐professed prophet, religious zealot, and racist, who has kept his “heir” under lock and key in the floating city of Columbia. Booker DeWitt is a washed‐up, disgraced ex‐Pinkerton agent haunted by his participation in the Wounded Knee Massacre. He enters Columbia to rescue Elizabeth in exchange for having his gambling debts settled. After much bloodshed, Booker saves Elizabeth and kills Comstock. In the past, Booker attended a baptism to assuage his guilt (...) over Wounded Knee. In some worlds he rejected the baptism, got married, had a daughter, Anna, and ended up as an indebted alcoholic ex‐Pinkerton agent. In the Comstock world, Anna is renamed Elizabeth in order to conceal her true origins. BioShock Infinite paints a metaphysical picture that treats the many‐worlds interpretation of quantum mechanics as reality. (shrink)

The story of the Vox Populi embodies conflict theory, one popular interpretation of Marx's ideas, portraying a bloody revolution that loses sight of its ideals, turns anarchistic, and becomes the new oppressor. In Columbia, Zachary Hale Comstock and Jeremiah Fink illustrate the way the bourgeoisie may come to create and control the means of production. As the friction builds between the bourgeoisie and the proletariat, historical processes contribute to the inevitable collapse of capitalism. In BioShock Infinite, the simmering (...) friction between the upper and lower classes boils over into the rise of the Vox Populi. The functionalist perspective often casts religion as a social structure that keeps society together despite any negative costs it may have for any particular group. In order for the bourgeoisie to own the means of production and keep the working class oppressed, it uses propaganda and indoctrination as powerful agents of control. (shrink)

This chapter concerns the role accorded to animals in the theories of the English-speaking philosophers who created the field of environmental ethics in the latter half of the twentieth century. The value of animals differs widely depending upon whether one adopts some version of Holism (value resides in ecosystems) or some version of Animal Individualism (value resides in human and nonhuman animals). I examine this debate and, along the way, highlight better and worse ways to conduct ethical arguments. I explain (...) that two kinds of appeals (which I call intuition and reductio) are questionable foundations for environmental ethics and that representatives of both schools occasionally appeal unhelpfully to intuition or caricature the commitments of the other side. I review two stronger arguments for Ecoholism (inference and eco-organisms) and show that they have performed a useful function in environmental ethics. Ultimately, however, both arguments fail because their proponents are unable to answer four critical objections: weakness of will, no eco-organisms, no teleology, and is/ought. I then show that Animal Individualism operates on more secure footing when it comes to philosophical and scientific assumptions. I also propose that Animal Individualism is more likely to prove effective in establishing progressive environmental policies insofar as it builds on existing legal concepts, especially the concept of moral rights, and political institutions, such as democratic states. I note that wild animals are not inherently more valuable than domestic animals and, finally, offer a brief outline of an animal rights environmental ethic. (shrink)

This article defends deterrence as an aim of punishment. Specifically, I contend that a system of punishment aimed at deterrence (with constraints to prohibit punishing the innocent or excessively punishing the guilty) is consistent with the liberal principle of respect for offenders as autonomous moral persons. I consider three versions of the objection that deterrent punishment fails to respect offenders. The first version, raised by Jeffrie Murphy and others, charges that deterrent punishment uses offenders as mere means to securing the (...) social good of crime reduction. The second and third are developed by R.A. Duff. The second holds that deterrent punishment inappropriately excludes offenders from the moral community. The third charges that deterrent punishment offers community members the wrong sorts of reasons to comply with the law. I conclude that each of these objections fails. A system of punishment aimed at deterrence (suitably constrained) is consistent with respect for offenders as moral persons. (shrink)

What can neuroscience tell us, if anything, about the capacities of cows to think about the future? The question is important if having the right to a future requires the ability to think about one’s future. To think about one’s future involves the mental state of prospection, in which we direct our attention to things yet to come. I distinguish several kinds of prospection, identify the behavioral markers of future thinking, and survey what is known about the neuroanatomy of future-directed (...) bovine beliefs and desires. I suggest, in conclusion, that instead of asking whether a cow’s prospection is conscious, ask whether it is like ours—with “ours” understood to include all human beings. (shrink)

In the voluminous literature on the subject of bovine growth hormone (bGH) we have yet to find an attempt to frame the issue in specifically moral terms or to address systematically its ethical implications. I argue that there are two moral objections to the technology: its treatment of animals, and its dislocating effects on farmers. There are agricultural biotechnologies that deserve funding and support. bGH is not one of them.

The field of `science and religion' is exploding in popularity among both academics and the reading public. This is a comprehensive and authoritative introduction to the debate, written by the leading experts yet accessible to the general reader.

Essays cover U.S. farm policy, the current plight of the small farmer, the history of the family farm, and the ethical, and financial issues.

This paper tests some recent paradigms for dealing with religious change against the evidence of Yoruba studies.

Much work in the philosophy of religion has been devoted to exploring the virtue of faith. Very little of it, however, has done so from the perspective of Christian worship and liturgical practice. In this essay, I explore the virtue of faith, articulated in a traditionally Catholic manner, as it is practiced, engaged, and deepened through participation in the Eucharist. I begin by emphasizing both the cognitive and the volitional dimensions of a robust conception of the virtue of faith and (...) then show how devout Eucharistic practice confirms and strengthens them, affording believers a unique opportunity to deepen their belief and concretely strengthen their trust in God. I conclude by noting how a Eucharistic approach to faith can avoid a common criticism—that faith is exceedingly passive—and also help us to understand why faith and religious practice can so easily become stagnant.

According to the moral error theory, there are no moral facts: all moral judgements are systematically and uniformly false. A popular strategy in recent years for arguing against the moral error theory is to deploy a companions in guilt argument. According to CG theorists, arguments for the moral error theory are insufficient, because either they rely on premises which do not warrant scepticism about moral facts, or they threaten to support an implausible error theoretic conclusion in other areas of discourse (...) – areas which seem safe from such a conclusion. This thesis deploys a CG argument in order to defend moral realism – roughly, the view that moral judgements purport to state facts and that some of those judgements have true contents – against one influential argument for the error theory: J. L. Mackie’s argument from queerness. The CG argument deployed depends on the assumption that doxastic normativism is true. Doxastic normativism is a metaphysical thesis according to which norms are in some sense constitutive of, or essential to, belief. Since my CG argument only works on the assumption that doxastic normativism is true, much of this thesis is spent defending normativism against some of its influential detractors. (shrink)

Attribution theorists assume that character information informs judgments of blame. But there is disagreement over why. One camp holds that character information is a fundamental determinant of blame. Another camp holds that character information merely provides evidence about the mental states and processes that determine responsibility. We argue for a two-channel view, where character simultaneously has fundamental and evidential effects on blame. In two large factorial studies (n = 495), participants rate whether someone is blameworthy when he makes a mistake (...) (burns a cake or misses a bus stop). Although mental state inferences predict blame judgments, character information does not. Using mediation analyses, we find that character information influences responsibility via two channels (Studies 3–4; n = 447), which are sensitive to different kinds of information (Study 5; n = 149). On the one hand, forgetfulness increases judgments of responsibility, because mental lapses manifest an objectionable character flaw. On the other hand, forgetfulness decreases judgments of state control, which in turn decreases responsibility judgments. These two channels cancel out, which is why we find no aggregate effect of forgetfulness on responsibility. Our results challenge several fundamental assumptions about the role of character information in moral judgment, including that good character typically mitigates blame. (shrink)

According to one recently popular “flicker of freedom” style response to Frankfurt-style arguments against the Principle of Alternative Possibilities—the “Triple O” flicker strategy—agents in Frankfurt-style cases are really or most fundamentally morally responsible for performing an action (A-ing) on their own, but not for A-ing simpliciter. This essay has two related aims. First, I offer an interpretation of the Triple O strategy which insulates it against an objection raised by Carolina Sartorio in “Flickers of Freedom and Moral Luck.” Second, I (...) argue that a sub-version of the strategy (“the inheritance view”) according to which agents in Frankfurt-style cases are derivatively responsible for A-ing simpliciter in virtue of A-ing on their own, for which they are basically responsible, is untenable. I show that “A-ing simpliciter” is not plausibly an outcome of “A-ing on one’s own” in the sense required for the transfer of responsibility. Several candidates for the generative relation via which responsibility might be transferred are canvassed, and it is found that none of these relations plausibly hold between an agent’s A-ing on his own and his A-ing simpliciter. Next, I identify the generative relation (if any) that does hold between these items and show that the direction of generation problematically conflicts with the direction of the inheritance view’s purported transfer of responsibility.

In this chapter, Gary Comstock considers whether it is ethically justified to pursue genetically modified ( GM) crops and foods. He first considers intrinsic objections to GM crops that allege that the process of making GMOs is objectionable in itself. He argues that there is no justifiable basis for the objections- i.e. GM crops are not intrinsically ethically problematic. He then considers extrinsic objections to GM crops, including objections based on the precautionary principle, which focus on the potential harms (...) that may result from the adoption of GM organisms. He argues that these concerns have some merit. However, they do not justify giving up GM crops altogether. Instead, they require that GM crops be developed carefully and with appropriate oversight. Comstock then presents the positive case for GM crops that he endorses. It is based on three considerations: (i) the right of people to choose to adopt GM technology; (ii) the balance of likely benefits over harms to consumers and the environment from GM technology; and (iii) the wisdom of encouraging discovery, innovation, and careful regulation of GM technology.

Although mind-wandering occupies up to half of our waking thoughts, it is seldom discussed in philosophy. My paper brings these neglected thoughts into focus. I propose that mind-wandering is unguided attention. Guidance in my sense concerns how attention is monitored and regulated as it unfolds over time. Roughly speaking, someone’s attention is guided if she would feel pulled back, were she distracted from her current focus. Because our wandering thoughts drift unchecked from topic to topic, they are unguided. One motivation (...) for my theory is what I call the “Puzzle of the Purposeful Wanderer”. On the one hand, mind-wandering seems essentially purposeless; almost by definition, it contrasts with goal-directed cognition. On the other hand, empirical evidence suggests that our minds frequently wander to our goals. My solution to the puzzle is this: mind-wandering is purposeless in one way—it is unguided—but purposeful in another—it is frequently caused, and thus motivated, by our goals. Another motivation for my theory is to distinguish mind-wandering from two antithetical forms of cognition: absorption and rumination. Surprisingly, previous theories cannot capture these distinctions. I can: on my view, absorption and rumination are guided, whereas mind-wandering is not. My paper has four parts. Section 1 spells out the puzzle. Sections 2 and 3 explicate two extant views of mind-wandering—the first held by most cognitive scientists, the second by Thomas Metzinger. Section 4 uses the limitations of these theories to motivate my own: mind-wandering is unguided attention. (shrink)

Perhaps the central question in action theory is this: what ingredient of bodily action is missing in mere behavior? But what is an analogous question for mental action? I ask this: what ingredient of active, goal-directed thought is missing in mind-wandering? My answer: attentional guidance. Attention is guided when you would feel pulled back from distractions. In contrast, mind-wandering drifts between topics unchecked. My unique starting point motivates new accounts of four central topics about mental action. First, its causal basis. (...) Mind-wandering is a case study that allows us to tease apart two causes of mental action––guidance and motivation. Second, its experiential character. Goals are rarely the objects of awareness; rather, goals are “phenomenological frames” that carve experience into felt distractions and relevant information. Third, its scope. Intentional mind-wandering is a limit case of action where one actively cultivates passivity. Fourth, my theory offers a novel response to mental action skeptics like Strawson. (shrink)

We present ethical reasons that the court should grant the Nonhuman Rights Project’s (NhRP) request for habeas corpus relief for Happy, an elephant. Happy has a basic interest in not being confined, an interest that should be legally protected just as the human interest in not being confined is legally protected. Since the decision in The Nonhuman Rights Project, Inc. v Breheny failed to weigh Happy’s interests properly, we ask this body to correct the error.

Should the law recognize an elephant’s right to be released from solitary confinement? The New York State Court of Appeals—the highest court in the State of New York—will consider this question on May 18. At issue is an Asian elephant named Happy. But happy she is not. Every human being has a right to bodily liberty because they have strong interests that this right protects. Since Happy has the same strong interests, the Court should recognize Happy’s right to be freed (...) from solitary confinement. (shrink)

We submit this brief in support of the Nonhuman Rights Project’s efforts to secure habeas corpus relief for the elephant named Happy. The Supreme Court, Bronx County, declined to grant habeas corpus relief and order Happy’s transfer to an elephant sanctuary, relying, in part, on previous decisions that denied habeas relief for the NhRP’s chimpanzee clients, Kiko and Tommy. Those decisions use incompatible conceptions of ‘person’ which, when properly understood, are either philosophically inadequate or, in fact, compatible with Happy’s personhood.

In this paper, I attempt to consider Jewish philosophy in opposition to the anti-ocularcentrism that defined the German Jewish philosophical tradition after Kant, namely the idea that Judaism—or at least its philosophical expression in Maimonidean philosophy—is aniconic and cognitively abstract. I do so by attempting to rethink the epistemic-veridical place of the imagination and visual experience in the Guide of the Perplexed . Once the imagination has been disciplined by reason, is there any cognitive status to an image or sound (...) that the eye or the ear perceives, and to that mental faculty that combines and recombines such impressions? Is the sight or sound of revelation a hallucination or just a mere figure of speech? Does it bear any relation to a spiritual reality external to the human mind and finite physical existence? To address these questions I explore the visual images, both iconic and aniconic-abstract, that distinguish the Guide . There is no getting past the visual imagination, although I am not sure Maimonides would have recognized it as such. Even when he leaves behind figurative visual cues such as the false image-work of the undisciplined imagination or the appearance of angels and images of God found in lower grades of prophecy, he turns to another visual register, namely the “abstract art“ of pure, dazzling light. In regard to these questions, Maimonides was more Greek than German, ascribing, cautiously, penultimate cognitive status to the visual imagination. (shrink)

Not long ago, interreligious conversations were regulated by the ideals of truth, goodness, and beauty. We are suspicious of these noble sounding ideals today. In a world of liberation theology, feminist criticism, and the hermeneutics of suspicion, can there be any new, “postmodern,” rules to govern our religious dialogues? Not able to consult any general theory, or “metanarrative,” in order to provide the answer, I simply tell the story of the only postmodern Catholic I have ever known. On the basis (...) of that experience, I argue that something like the old rules will have to accompany us into the new age. (shrink)

Social studies of interdisciplinary science investigate how scientific collaborations approach complex challenges that require multiple disciplinary perspectives. In order for collaborators to meet these complex challenges, interdisciplinary collaborations must develop and maintain integrative capacity, understood as the ability to anticipate and weigh tradeoffs in the employment of different disciplinary approaches. Here we provide an account of how one group of interdisciplinary fog scientists intentionally catalyzed integrative capacity. Through conversation, collaborators negotiated their commitments regarding the ontology of fog systems and the (...) methodologies appropriate to studying fog systems, thereby enhancing capabilities which we take to constitute integrative capacity. On the ontological front, collaborators negotiated their commitments by setting boundaries to and within the system, layering different subsystems, focusing on key intersections of these subsystems, and agreeing on goals that would direct further investigation. On the methodological front, collaborators sequenced various methods, anchored methods at different scales, validated one method with another, standardized the outputs of related methods, and coordinated methods to fit a common model. By observing the process and form of collaborator conversations, this case study demonstrates that social studies of science can bring into critical focus how interdisciplinary collaborators work toward an integrated conceptualization of study systems.

In the recent book The Compatibility of Evolution and Design, E. V. R. Kojonen argues that a biological design inference is still possible in light of mainstream evolutionary theory and that evolution and design need not be in explanatory tension.

Contributors come from diverse academic backgrounds across philosophy, science, and theology, and both critique and extend Kojonen's argument.

We submit this brief in support of the Nonhuman Rights Project’s efforts to secure habeas corpus relief for the elephant named Happy. We reject arbitrary distinctions that deny adequate protections to other animals who share with protected humans relevantly similar vulnerabilities to harms and relevantly similar interests in avoiding such harms.

Although scientists dating back to Darwin have noted the importance of the body in communicating emotion, current research on emotion communication tends to emphasize the face. In this article we review the evidence for bodily expressions of emotions—that is, the handful of emotions that are displayed and recognized from certain bodily behaviors (i.e., pride, joy, sadness, shame, embarrassment, anger, fear, and disgust). We also review the previously developed coding systems available for identifying emotions from bodily behaviors. Although no extant coding (...) system provides an exhaustive list of bodily behaviors known to communicate a panoply of emotions, our review provides the foundation for developing such a system.

Environmental ethics consists of a set of competing theories about whether human actions and attitudes to nature are morally right or wrong. Ecocentrists are holists whose theory locates the primary site of value in biological communities or ecosystems and who tend to regard actions interfering with the progress of an ecosystem toward its mature equilibrium state as prima facie wrong. I suggest that this form of ecocentrism may be built on a questionable scientific foundation, organismic ecology, and that a better (...) scientific foundation for environmental ethics may be found in individualistic neo-Darwinian population biology. However, the latter approach probably requires a corresponding shift away from ethical holism and toward approaches locating value primarily in individuals. I call such environmental ethicists ‘extensionists’ and briefly outline an extensionist environmental ethic. (shrink)

Throughout the 19th century, the discourse on idiocy was among the most substantial and celebrated fields of knowledge about human nature; yet it is mostly forgotten or ignored by scholars today. Once science could identify the truly retarded individual from within the confused concept of idiocy, it is thought, these subjects could finally be treated separately and more humanely. But looking back at the early discourse on idiocy reveals a rational knowledge of the subject built on a very different intelligibility (...) from our own. Indeed, until modern times, idiocy was actually considered a form of madness, and it was only through the emergence of a new intelligibility of the body—based on the idea of development—that the concept of retardation could emerge. Rather than through medical or humanistic advance, it was first through the emergence of the normalizing technologies of the hospitals and schools that society would find new reasons and means for dealing with these ‘recalcitrant’ figures who were unwilling or unable to conform to the requirements and goals of the institutional disciplines. A new intelligibility of the idiot based on new disciplinary technologies would provide the basis not only for the mentally retarded subject, but eventually for all of the behavioral disorders of childhood. This article will be of interest to scholars and educators interested in the history of the modern developmental subject, pedagogy, and the appearance of the norm in constructing knowledge of the subject and the ordering of behaviors.

A copy of the book is available from my website.

The original essays in this book address the influential writings of Peter A. French on the nature of responsibility, ethics, and moral practices. French’s contributions to a wide spectrum of philosophical discussions have made him a dominant figure in the fields of normative ethics, meta-ethics, applied ethics, as well as legal and political philosophy. Many of French’s deepest insights come from identifying and exploring the scope and nature of moral responsibility and human agency as they appear in actual events, real (...) social and cultural practices, as well as in literature and film. This immediacy renders French’s scholarship vital and accessible to a wide variety of audiences. The authors, recognized for their own contributions to the understanding of the nature of morality and moral practices offer new and unique positions while exploring, expanding and responding to those of French. The final chapter is written by French, in which he provides both new philosophical insight as well as some reflection on his own work and its influence. This book will appeal to philosophers, as well as advanced students and researchers in the humanities, social sciences, law, and political science. (shrink)

This study tested four theoretical models of leadership with data from the ethnographic record. The first was a game-theoretical model of leadership in collective actions, in which followers prefer and reward a leader who monitors and sanctions free-riders as group size increases. The second was the dominance model, in which dominant leaders threaten followers with physical or social harm. The third, the prestige model, suggests leaders with valued skills and expertise are chosen by followers who strive to emulate them. The (...) fourth proposes that in small-scale, kin-based societies, men with high neural capital are best able to achieve and maintain positions of social influence (e.g., as headmen) and thereby often become polygynous and have more offspring than other men, which positively selects for greater neural capital. Using multiple search strategies we identified more than 1000 texts relevant to leadership in the Probability Sample of 60 cultures from the Human Relations Area Files (HRAF). We operationalized the model with variables and then coded all retrieved text records on the presence or absence of evidence for each of these 24 variables. We found mixed support for the collective action model, broad support for components of the prestige leadership style and the importance of neural capital and polygyny among leaders, but more limited support for the dominance leadership style. We found little evidence, however, of emulation of, or prestige-biased learning toward, leaders. We found that improving collective actions, having expertise, providing counsel, and being respected, having high neural capital, and being polygynous are common properties of leaders, which warrants a synthesis of the collective action, prestige, and neural capital and reproductive skew models. We sketch one such synthesis involving high-quality decision-making and other computational services. (shrink)

Aaron Zimmerman presents a new pragmatist account of belief, in terms of information poised to guide our more attentive, controlled actions. And he explores the consequences of this account for our understanding of the relation between psychology and philosophy, the mind and brain, the nature of delusion, faith, pretence, racism, and more.

Descartes maintains that we can love God and that it is pleasant and morally beneficial to do so. In this essay, I examine the necessary conditions for such an intellectual love of God. I argue that the intellectual love of God is incited by a judgment that we are joined to God in reality, which is constitutive of an intellectual joy. I go on to show that the intellectual love of God is, itself, constituted by a stripping of our private (...) interests in favor of God’s divine will. (shrink)

One widely-endorsed argument in the experimental philosophy literature maintains that intuitive judgments are unreliable because they are influenced by the order in which thought experiments prompting those judgments are presented. Here, we explicitly state this argument from ordering effects and show that any plausible understanding of the argument leads to an untenable conclusion. First, we show that the normative principle is ambiguous. On one reading of the principle, the empirical observation is well-supported, but the normative principle is false. On the (...) other reading, the empirical observation has only weak support, and the normative principle, if correct, would impugn the reliability of deliberative reasoning, testimony, memory, and perception, since judgments in all these areas are sensitive to ordering in the relevant sense. We then reflect on what goes wrong with the argument. (shrink)

For decades, scholars in the social sciences and humanities have questioned the appropriateness and utility of prior review of their research by human subjects' ethics committees. This essay seeks to organize thematically some of their published complaints and to serve as a brief restatement of the major critiques of ethics review. In particular, it argues that 1) ethics committees impose silly restrictions, 2) ethics review is a solution in search of a problem, 3) ethics committees lack expertise, 4) ethics committees (...) apply inappropriate principles, 5) ethics review harms the innocent, and 6) better options exist.

In this letter, we argue that an economic perspective on the mind has played—and should continue to play—a central role in the development of cognitive science. Viewing cognition as the productive application of mental resources puts cognitive science and economics on a common conceptual footing, paving the way for closer collaboration between the two disciplines. This will enable cognitive scientists to more readily repurpose economic concepts and analytical tools for the study of mental phenomena, while at the same time, enriching (...) our understanding of the modern economy, which is increasingly driven by mental, rather than physical, production.

Motivated reasoning occurs when we reason differently about evidence that supports our prior beliefs than when it contradicts those beliefs. Adult participants (N = 377) from Amazon’s Mechanical Turk (MTurk) system completed written responses critically evaluating strengths and weaknesses in a vignette on the topic of anthropogenic climate change (ACC). The vignette had two fictional scientists present prototypical arguments for and against anthropogenic climate change that were constructed with equally flawed and conflicting reasoning. The current study tested and found support (...) for three main hypotheses: cognitive style, personality, and ideology would predict both motivated reasoning and endorsement of human caused climate change; those who accept human-caused climate change will be less likely to engage in biased reasoning and more likely to engage in objective reasoning about climate change than those who deny human activity as a cause of climate change.

Crump et al.’s contribution to assessing whether decapods feel pain raises an important question: Is pain distributed unevenly across the order? The case for pain appears stronger in Pleocyemata than in Dendrobranchiata. Some studies report pain avoidance behaviors in Dendrobranchiata (Penaeidae) shrimp, but further studies are needed to determine whether the chemicals used are acting as analgesics to relieve pain, or as soporifics to reduce overall alertness. If the latter, the most farmed shrimp species may not require the same level (...) of protection as crabs, crayfish, and lobsters. (shrink)
