Aging is accompanied by stereotyped changes in functional brain activations, for example a cortical shift in activity patterns from posterior to anterior regions is one hallmark revealed by functional magnetic resonance imaging (fMRI) of aging cognition. Whether these neuronal effects of aging could potentially contribute to an amelioration of or resistance to the cognitive symptoms associated with psychopathology remains to be explored. We used a visual illusion paradigm to address whether aging affects the cortical control of perceptual beliefs and biases. (...) Our aim was to understand the effective connectivity associated with volitional control of ambiguous visual stimuli and to test whether greater top-down control of early visual networks emerged with advancing age. Using a bias training paradigm for ambiguous images we found that older participants (n = 16) resisted experimenter-induced visual bias compared to a younger cohort (n = 14) and that this resistance was associated with greater activity in prefrontal and temporal cortices. By applying Dynamic Causal Models for fMRI we uncovered a selective recruitment of top-down connections from the middle temporal to Lingual gyrus (LIN) by the older cohort during the perceptual switch decision following bias training. In contrast, our younger cohort did not exhibit any consistent connectivity effects but instead showed a loss of driving inputs to orbitofrontal sources following training. These findings suggest that perceptual beliefs are more readily controlled by top-down strategies in older adults and introduce age-dependent neural mechanisms that may be important for understanding aberrant belief states associated with psychopathology.

All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

This paper discusses three potential varieties of update: updates to the common ground, structuring updates, and updates that introduce discourse referents. These different types of update are used to model different aspects of natural language phenomena. Not-at-issue information directly updates the common ground. The illocutionary mood of a sentence structures the context. Other updates introduce discourse referents of various types, including propositional discourse referents for at-issue information. Distinguishing these types of update allows a unified treatment of a broad range of (...) phenomena, including the grammatical evidentials found in Cheyenne (Algonquian) as well as English evidential parentheticals, appositives, and mood marking. An update semantics that can formalize all of these varieties of update is given, integrating the different kinds of semantic contributions into a single representation of meaning. (shrink)

Many languages grammatically mark evidentiality, i.e., the source of information. In assertions, evidentials indicate the source of information of the speaker while in questions they indicate the expected source of information of the addressee. This dissertation examines the semantics and pragmatics of evidentiality and illocutionary mood, set within formal theories of meaning and discourse. The empirical focus is the evidential system of Cheyenne (Algonquian: Montana), which is analyzed based on several years of fieldwork by the author.

This collection examines the question of nonhuman animal agency by shifting emphasis from the human perspective toward that of other animals, exploring modes of ...

In this paper, I propose that the distinction between what is at-issue and what is not can be modeled as a distinction between two components of assertion. These two components affect the common ground in different ways. The at-issue component of an assertion, which is negotiable, is treated as a proposal to update the common ground. The not-at-issue component of an assertion, which is not negotiable, is added directly to the common ground. Evidence for this proposal comes from evidentials, which (...) I argue grammaticize this distinction. It has been observed that sentences with evidentials make both an ‘evidential’ and a ‘propositional’ contribution (Faller 2002, 2006, Matthewson et al. 2008). The evidential contribution is not directly challengeable or up for negotiation. In contrast, the propositional contribution, the ‘main point’ of the sentence, is directly challengeable and up for negotiation. I analyze these two contributions of evidentials as the not-at-issue component of assertion and the at-issue component of assertion, respectively. Supporting data comes from Cheyenne, a language with evidentials that are part of the illocutionary mood paradigm. (shrink)

Language and culture endow humans with access to conceptual information that far exceeds any which could be accessed by a non-human animal. Yet, it is possible that, even without language or specific experiences, non-human animals represent and infer some aspects of similarity relations between objects in the same way as humans. Here, we show that monkeys’ discrimination sensitivity when identifying images of animals is predicted by established measures of semantic similarity derived from human conceptual judgments. We used metrics from computer (...) vision and computational neuroscience to show that monkeys’ and humans’ performance cannot be explained by low-level visual similarity alone. The results demonstrate that at least some of the underlying structure of object representations in humans is shared with non-human primates, at an abstract level that extends beyond low-level visual similarity. Because the monkeys had no experience with the objects we tested, the results suggest that monkeys and humans share a primitive representation of object similarity that is independent of formal knowledge and cultural experience, and likely derived from common evolutionary constraints on object representation.

Sarah E. Wilson, University of Central LancashireThis paper's account of the core issues at stake in relation to genetic enhancement is presented as an alternative to mainstream liberal defenses of enhancement. The mainstream arguments are identified as being associated with reproductive autonomy, individual choice, and a `neutral', passive interpretation of technology. The alternative account is associated with the perspective of `woman' or child-bearer, with a fundamental concern for social justice, and an understanding of society in both a global and (...) a contextual sense. This paper adopts a theoretical framework informed by feminist ethics, particularly a feminist ethic of care. The paper begins by outlining some of the key points of the care perspective, highlighting how this contrasts with a mainstream `justice' perspective, and illustrating how this is reflected in arguments relating to genetic enhancement. The paper then turns to a consideration of how a care perspective might be applied to questions of genetic enhancement, and how this may bring forward new issues. This includes in particular a consideration of IVF technologies and how applying understandings from research into this area brings forward usually unaddressed concerns in considering genetic enhancement. The final section of the paper covers some of the questions that there is space to ask once the narrow focus on individual rights is overcome. (shrink)

In this fascinating book, Sarah Worth addresses from a philosophical perspective the many ways in which reading benefits us morally, socially and cognitively.

This book provides a compositional, truth-conditional, crosslinguistic semantics for evidentiality, the linguistic encoding of the source of information on which a statement is based. Central to the proposed theory is the distinction between what propositional content is at-issue and what content is not-at-issue. Evidentials contribute not-at-issue content, and can affect the level of commitment a sentence makes to the main proposition, contributed by sentential mood. In this volume, Sarah Murray builds on recent work in the formal semantics of evidentials (...) and related phenomena, and proposes a semantics that does not appeal to separate dimensions of illocutionary meaning. Instead, she argues that all sentences make three contributions: at-issue content, not-at-issue content, and an illocutionary relation. At-issue content is presented and made available for subsequent anaphora, but is not directly added to the common ground; not-at-issue content directly updates the common ground; and the illocutionary relation uses the at-issue content to impose structure on the common ground, which, depending on the clause type, can trigger further updates. 0The analysis is supported by extensive empirical data from Cheyenne, drawn from the author's own fieldwork, as well as from English and a variety of other languages.

On one view, the point of an assertion is to update the common ground (Stalnaker 1978, Karttunen 1974). On another, the point of an assertion is to propose an update to the com- mon ground (Groenendijk 2009, Mascarenhas 2009, and related work on the structure of discourse, e.g., Ginzburg 1996, Roberts 1996, Gunlogson 2001). In Murray (to appear), I merge these two views. I argue based on evidence from declarative sentences with eviden- tials that assertion has two components: what is (...) at-issue and what is not. The not-at-issue component of assertion is added directly to the common ground while the at-issue compo- nent is proposed to be added to the common ground. Here, I extend this analysis to yes/no questions in Cheyenne and their interaction with evidentials. I propose that the distinction between what is at-issue and what is not is also present in questions, and that it can be modeled in the same way. Specifically, both declarative and interrogative sentences make two contributions: they restrict and structure the common ground. The restriction is based on the not-at-issue component while the structuring relation is based on the at-issue component. (shrink)

Research focused on the prodromal period prior to the onset of psychosis is essential for the further development of strategies for early detection, early intervention, and disease pre-emption. Such efforts necessarily require the enrollment of individuals who are at risk of psychosis but have not yet developed a psychotic illness into research and treatment protocols. This work is becoming increasingly internationalized, which warrants special consideration of cultural differences in conceptualization of mental illness and international differences in health care practices and (...) rights regarding research participation. The process of identifying and requesting informed consent from individuals at elevated risk for psychosis requires thoughtful communication about illness risk and often involves the participation of family members. Empirical studies of risk reasoning and decisional capacity in young people and individuals with psychosis suggest that most individuals who are at-risk for psychosis can adequately provide informed consent; however ongoing improvements to tools and procedures are important to ensure that this work proceeds with maximal consideration of relevant ethical issues. This review provides a discussion of these issues in the context of international research efforts. (shrink)

In her book Specifications Grading, Linda B. Nilson advocates for a grading regimen she claims will save faculty time, increase student motivation, and improve the quality and rigor of student work. If she is right, there is a strong case for many faculty to adopt some version of the system she recommends. In this paper, we argue that she is mostly right and recommend that faculty move away from traditional grading. We begin by rehearsing the central features of specifications grading (...) and providing two examples of how to implement it in philosophy classes. In light of the examples, we argue that specifications grading fulfills two of Nilson’s central desiderata but not the third. Since specifications grading generates two benefits that when combined increase student learning, without adding or increasing burdens, we conclude that student learning increases when courses are revised to include aspects of specifications grading.

Philosophers of literature direct their studies to the moral, cognitive, and emotional aspects of our involvement with fiction. In spite of this, they rarely engage works of popular fiction. In this paper I use The Da Vinci Code as a case study of the impact of popular fiction on readers in terms of these three areas. Although this book will never be considered good literature, its impact is far reaching. l address concerns dealing with the fiction/non-fiction distinction as weIl as (...) issues with history, accuracy, and falsehoods. I flesh out the issues The Da Vinci Code brings up and argue that it, along with other works of popular fiction (Oprah’s book club for example), might be taken more seriously by philosophers of literature.

In English, two deictic space-time metaphors are in common usage: the Moving Ego metaphor conceptualizes the ego as moving forward through time and the Moving Time metaphor conceptualizes time as moving forward toward the ego . Although earlier research investigating the psychological reality of these metaphors has typically examined spatial influences on temporal reasoning , recent lines of research have extended beyond this, providing initial evidence that personality differences and emotional experiences may also influence how people reason about events in (...) time . In this article, we investigate whether these relationships have force in real life. Building on the effects of individual differences in self-reported conscientiousness and procrastination found by Duffy and Feist , we examined whether, in addition to self-reported conscientiousness and procrastination, there is a relationship between conscientious and procrastinating behaviors and temporal perspective. We found that participants who adopted the Moving Time perspective were more likely to exhibit conscientious behaviors, while those who adopted the Moving Ego perspective were more likely to procrastinate, suggesting that the earlier effects reach beyond the laboratory.

Most, if not all, psychologists have served as teaching or research assistants during graduate school, been instructed by teaching assistants, or both. As both faculty and students themselves, graduate assistants are faced with several dilemmas for which they typically have little preparation or guidance. These issues are explored in the context of the existing literature on multiple relationships in academic settings. Recommendations are made for graduate assistants, their faculty supervisors or mentors, and administrators to proactively address and confront these challenges (...) in a manner consistent with the profession of psychology's ethics code and to minimize the potential for harm to those we are entrusted to teach.

An important role for all health care professionals is to be an advocate for their patients, and there is no question that many patients need advocacy to reach their health care goals. The role of advocate takes many forms, but one is to speak up when one is concerned for the safety or well‐being of a patient. A nurse is often the member of a health care team most likely to notice changes that might signal problems or poor responses to (...) treatment. The duty of the nurse is to speak up in a timely and urgent manner when the nurse believes—or fears—that the patient's safety may be at risk. Yet the role of nurses as advocates for their patients has assumed near‐mythic status. Rather than seeing advocate as one among many equally important and interrelated professional roles, the nurse, when asked, “Who are you?” is likely to give the heartfelt and passionate answer, “The patient's advocate!” This essay examines and critically analyzes the advocacy role adopted by the nursing profession and outlines the challenges it has created to nursing's contributions to collaborative practice, ethics, and policy in health care.

Earth system science (ESS) has identified worrying trends in the human impact on fundamental planetary systems. In this conceptual article, we discuss the implications of this research for business schools and management education (ME). We argue that ESS findings raise significant concerns about the relationship between business and nature and, consequently, a radical reframing is required to embed economic and social activity within the global sustainability of natural systems. This has transformative implications for ME. To illustrate this reframing, we apply (...) the ESS lenses of social-ecological interdependence, multiscalar relations, environmental governance, and environmental values to the ME functional domains of institutional purpose, social context and engagement, pedagogical practice, curricular design, and research focus. Our work contributes to the literature on business education for sustainability and the business-society-nature nexus. We explore and apply key ESS findings and concepts, discuss normative implications of these ideas, and offer guidance on transformational pathways for business schools and ME. (shrink)

In languages like English, reflexivity and reciprocity are expressed by distinct proforms. However, many languages, such as Cheyenne, express reflexivity and reciprocity with a single proform. In this paper I utilize Dynamic Plural Logic (van den Berg, 1996) to a draw a semantic parallel between reflexive and reciprocal anaphors in English. I propose that they contribute overlapping but distinct requirements on the relations introduced by transitive verbs, requirements which fully specify reflexivity and reciprocity. This parallel is then extended to Cheyenne (...) by appealing to underspecification. I propose the Cheyenne affix which expresses both reflexivity and reciprocity contributes only the shared requirement of the English anaphors. It is thus underspecified, not ambiguous. This accounts for its compatibility with both singular and plural antecedents as well as its variety of construals. (shrink)

In the last 50 years, multiauthored publications have become more prevalent, given the increasing number of collaborative, interdisciplinary, multicenter research studies. The determination of authorship credit and order is a difficult process, especially for graduate students, whose disadvantaged power position in research settings increases their vulnerability to exploitation. The American Psychological Association has published ethical standards for determining authorship credit, but the power difference inherent in the student-faculty relationship may complicate this ethical dilemma. The authors reviewed a number of previously (...) recommended strategies and proposed that determining authorship credit is most effectively facilitated through professional development. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Peaceful Persuasion: The Geopolitics of Nonviolent RhetoricSarah E. DempseyPeaceful Persuasion: The Geopolitics of Nonviolent Rhetoric. Ellen W. Gorsevski. Albany: State University of New York Press, 2004.pp. 262. $55.00, hardcover.The overriding emphasis on violence, militarization, and retribution within current geopolitical contexts demands that we acquire greater understandings of nonviolent communicative practices. In Peaceful Persuasion, author Ellen Gorsevski, Professor of English and Communication at Oregon State University, argues that nonviolent (...) rhetoric tends to be ignored by scholars—that its methods, strategies, and impacts are often passed over and that nonviolence is often framed as hopelessly utopian, unrealistic, and ineffective. Gorsevski situates her study of nonviolent rhetoric less within its humanistic and religious inheritance, drawing instead on a contrast with existing models of rhetoric. As a strategy for rhetorical and political action, Gorsevski takes nonviolence to be instructive of new ways to reconfigure both rhetorical studies and social movement strategy.It is important to note that Gorsevski's need to study peaceful means of relating to others is driven as much by a love of rhetorical theory as by a passion for translating an understanding of nonviolent rhetoric into strategies for activists. As such, this book provides a solid introduction to rhetorical theory, including an appendix on the connection between rhetoric and nonviolence that details what activists have to gain from each. In addition, instructors will find useful a chapter on the specifics of incorporating nonviolence into speech communication classrooms.Peaceful Persuasion's greatest contribution to rhetorical studies is the careful drawing out of the many ways that a rhetorical take on nonviolence has become increasingly necessary. To make this solid case, Gorsevski draws on four very diverse case studies of nonviolent rhetoric. In a move that is both surprising and refreshing, Gorsevski's case studies do more than provide exemplars of how critics may read nonviolence as a powerful rhetorical strategy; each helps to further delineate the key characteristics of what has been, until now, a relatively undefined area of rhetorical action.Gorsevski's gift to her readers is the ability to demonstrate the rich subtleties of nonviolence through very different contexts. The case studies [End Page 89] draw from such different sources that at first seem disorienting. Upon reflection, it becomes clearer that they greatly complicate our notions of nonviolence, redressing the disservices of previous bleary analyses that configured nonviolence only by its lack of violence rather than according to its fruitful range of seemingly contradictory strategies. The cavernous distances each study crosses illuminate the multiplicity of forms, meanings, and strategies that nonviolence may take. As such, any definition of nonviolence that I may provide in this short review does a serious disservice to the depth that Gorsevski creates through her sometimes disjointed case studies.The case studies serve at least dual purposes, as each provides an analysis that extends our understandings of nonviolence in action as it also offers instructive mini-lessons for the further development of rhetorical studies. In the first case study, Gorsevski provides a contextualized analysis of critics' interpretations of the film The Spitfire Grill, which she shows to be reflective of the "predominantly accepting orientation that rhetoric and film critics hold for the idea that humans are characterized by "innate aggression" and violence" (68). For Gorsevski, this study demonstrates that nonviolence as a lens can be applied to a range of texts just as well as any other approach to rhetoric. Gorsevski moves her analysis of nonviolent rhetoric into the geopolitical realm for her study of President of Macedonia Kiro Gligorov's historic first speech before the United Nations. She takes his speech as evidence of the usefulness of pragmatic nonviolence, which entails "noncooperation or defiance of political adversaries in order to decry a perceived injustice" (72). Gligorov's speech illustrates that nonviolence and violence are best seen less as equivalent than, rather, as operating on a sliding scale. For Gorsevski, successful use of pragmatic nonviolence may even include a measure of violence as long as it serves to reduce the escalation of further strife.Next Gorsevski explores the visual rhetoric of the gendered body of Burmese activist and Nobel Peace Prize winner Aung San Suu Kyi to show...

Bodily methodologies that engage with the affective, rhythmic, and temporal dimensions of movement have altered the landscape of social science and humanities research. Walking is one such methodology by which scholars have examined vital, sensory, material, and ephemeral intensities beyond the logics of representation. Extending this rich field, this article invokes the concept trans to reconceptualize walking research through theories that attend to the vitality and agency of matter, the interconnectedness between humans and non-humans, the importance of mediation and bodily (...) affect, and the necessity of acknowledging ethico-political responsibility. While theoretical and empirical research about embodied, emplaced, and sensorial relations between moving bodies and space are well developed in the field of walking studies, their entanglements become profoundly altered by theories of trans – transcorporeality, transspecies, and transmaterialities. Taking up trans theories we experiment in thinking-with a sonic art performance, Walking to the Laundromat, which probes bodily, affective, and gendered labour. (shrink)

We recommend that the future of religion and science involve more partnerships between scholars, amateurs, and artists. This reimagines an underdeveloped aspect of the history of religion and science.

Examined as an isolated situation, and through the lens of a rare and feared disease, Mr. Duncan's case seems ripe for second-guessing the physicians and nurses who cared for him. But viewed from the perspective of what we know about errors and team communication, his case is all too common. Nearly 440,000 patient deaths in the U.S. each year may be attributable to medical errors. Breakdowns in communication among health care teams contribute in the majority of these errors. The culture (...) of health care does not seem to foster functional, effective communication between and among professionals. Why? And more importantly, why do we not do something about it? (shrink)

Across cultures, people employ space to construct representations of time. English exhibits two deictic space–time metaphors: the “moving ego” metaphor conceptualizes the ego as moving forward through time and the “moving time” metaphor conceptualizes time as moving forward towards the ego. Earlier research investigating the psychological reality of these metaphors has shown that engaging in certain types of spatial-motion thinking may influence how people reason about events in time. More recently, research has shown that people’s interactions with cultural artifacts may (...) also influence their representations of time. Extending research on space–time mappings in new directions, three experiments investigated the role of cultural artifacts, namely calendars and clocks, in the interpretation of metaphorical expressions about time. Taken together, the results provide initial evidence that, in their interpretation of ambiguous metaphorical expressions about time, people automatically access and use spatial representations of absolute time, whereby moving forward in space corresponds with moving later in time. Moreover, asking participants to use a reverse space–time mapping causes interference, which is reflected through their temporal reasoning. (shrink)

This article draws on Donna Haraway’s call for feminist speculative fabulation as an approach to qualitative research methodologies and writing praxis in schools. The first section of the article outlines how I conceptualize speculative thought, through different philosophers and theorists, and provides a brief literature review of speculative fiction used in secondary English curricula. The article then focuses on an in school creative writing project with grade 9 English students. In the student examples that I attend to, speculative fabulations and (...) situated feminisms are entangled, rendered complex, and in tension. In the final section, I discuss the Whiteness of mainstream speculative fiction and argue that speculative fabulation must be accountable to situated feminisms in how we read, write, and conduct research.

The increased use of human biological material for cell-based research and clinical interventions poses risks to the privacy of patients and donors, including the possibility of re-identification of individuals from anonymized cell lines and associated genetic data. These risks will increase as technologies and databases used for re-identification become affordable and more sophisticated. Policies that require ongoing linkage of cell lines to donors’ clinical information for research and regulatory purposes, and existing practices that limit research participants’ ability to control what (...) is done with their genetic data, amplify the privacy concerns.

Plural reflexives and reciprocals are anaphoric not only to antecedent pluralities but also to relations between the members of those pluralities. In this paper, I utilize Dynamic Plural Logic (van den Berg 1996) to analyze reflexives and reciprocals as anaphors that elaborate on relations introduced by the verb, which can be collective, cumulative, or distributive. This analysis generalizes to languages like Cheyenne (Algonquian) where reflexivity and reciprocity are expressed by a single proform that I argue is underspecified, not ambiguous.

Christian ethicists rarely study apology or forgiveness about climate change, possibly because it is just another sin that God may forgive. Yet apology between humans may be critical to avoiding paralysis after people realize the horror of their actions and enabling cooperative responses to climate change among its perpetrators and victims. Climate change challenges traditional ideas and practices of apology because it involves unintentional, ongoing acts of diffuse collectives that harm other diffuse collectives across space and time. Developing concepts of (...) collective agency and responsibility enable a reconceptualization of apology for an era of climate change. While more work is needed to understand and implement such ideas, this paper lays the groundwork for future studies of collective apology and forgiveness by identifying general features of climate apologies including their symbolic dimensions and connection to ongoing changed actions.

Although environmental ethicists often focus on applying ethics to policy, the ethics embedded in policy documents such as Agenda 21 are also significant. Though largely ignored by ethicists after early responses to the document focused on intrinsic value, Agenda 21's ethics are particularly valuable for their ability to resonate with many people and link politics, technical studies, and ethics. For instance, their use draws attention to the need to ethically evaluate sustainability indexes and identifies limitations of existing indexes. At a (...) broad level, this study of the ethics of Agenda 21 also suggests that the ethics of international environmental policy documents deserves more attention. (shrink)

ABSTRACTIn 1651, Alexander Ross published an attack on Thomas Browne's Pseudodoxia Epidemica, Bacon's Natural History and William Harvey's De generatione. Ross's work, Arcana Microcosmi, defended Aristotelian natural philosophy against the ‘new philosophy’ that figures like Bacon, Harvey and Browne represented. Though Ross's attacks on these authors make up no more than half of the treatise’s contents, the book’s paratextual materials emphasise scientific debate. While Ross's authorial approach advocates reading exclusively ancient authorities for the sake of glossing and transmitting their knowledge (...) to a wider public, in order to argue against the new philosophy Ross must engage with its textual production. Furthermore, his works advertise their focus on Bacon, Harvey and Browne, which would have attracted a readership drawn to new scientific approaches to knowledge formation. Ross's polemic represents an effort to model his devotion to ancient authority while also generating a reading public that would resist the new approach to reading that the new philosophy proposed.

The purpose of this paper is to review critically Julian Savulescu's principle of 'Procreative Beneficence,' which holds that prospective parents are morally obligated to select, of the possible children they could have, those with the greatest chance of leading the best life. According to this principle, prospective parents are obliged to use the technique of pre-implantation genetic diagnosis (PGD) to select for the 'best' embryos, a decision that ought to be made based on the presence or absence of both disease (...) traits and non-disease traits such as intelligence. While several articles have been written in response to Savulescu's principle, none has systematically explored its philosophical underpinnings to demonstrate where it breaks down. In this paper I argue that the examples that Savulescu employs to support his theory in fact fail to justify it. He presents these examples as analogous to PGD, when in fact they differ from it in subtle but morally relevant ways. Specifically, Savulescu fails to acknowledge the fact that his examples evoke deontological and virtue ethics concerns that are absent in the context of PGD. These differences turn out to be crucial, so that, in the end, the analogies bear little support for his theory. Finally, I lay out the implications of this analysis for reproductive ethics. (shrink)
