© 2017. The American Astronomical Society. 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)

The following article presents preliminary reflections on a processual theory of health and disease. It does this by steering the discussion more toward an ontology of organisms rather than conceptual analysis of the semantic content of the terms “health” and “disease.” In the first section, four meta-theoretical assumptions of the traditional debate are identified and alternative approaches to the problems are presented. Afterwards, the view that health and disease are constituted by a dynamic relation between demands imposed on an organism (...) and individual presuppositions for adequate response is developed. In the last section, the paper takes stock of three possible objections to and clarifies some implications of this approach to the notions of health and disease. (shrink)

Traditionally, social entities (i.e., social properties, facts, kinds, groups, institutions, and structures) have not fallen within the purview of mainstream metaphysics. In this chapter, we consider whether the exclusion of social entities from mainstream metaphysics is philosophically warranted or if it instead rests on historical accident or bias. We examine three ways one might attempt to justify excluding social metaphysics from the domain of metaphysical inquiry and argue that each fails. Thus, we conclude that social entities are not justifiably excluded (...) from metaphysical inquiry. Finally, we ask how focusing on social entities could change the character of metaphysical inquiry. We suggest that starting from examples of social entities might lead metaphysicians to rethink the assumption that describing reality in terms of intrinsic, independent, and individualistic features is preferable to describing it in terms of relational, dependent, and non-individualistic features.

Former NAACP chapter head Rachel Dolezal's attempted transition from the white to the black race occasioned heated controversy. Her story gained notoriety at the same time that Caitlyn Jenner graced the cover of Vanity Fair, signaling a growing acceptance of transgender identity. Yet criticisms of Dolezal for misrepresenting her birth race indicate a widespread social perception that it is neither possible nor acceptable to change one's race in the way it might be to change one's sex. Considerations that support transgenderism (...) seem to apply equally to transracialism. Although Dolezal herself may or may not represent a genuine case of a transracial person, her story and the public reaction to it serve helpful illustrative purposes. (shrink)

Can ethical character be stimulated and enabled? Cognitive understanding of organizational ethics issues is important and necessary, but not sufficient. Ethical behavior does not emerge automatically. Effective political method is necessary. While it may be difficult to teach ethical character, nonetheless, skill development with respect to joined ethics understanding and action-learning methods can help us develop the skills and confidence we need to actualize our ethical characters and social concerns. An action-learning approach to organizational ethics can help stimulate and enable (...) ethical character. (shrink)

Miranda Fricker claims that a “gap” in collective hermeneutical resources with respect to the social experiences of marginalized groups prevents members of those groups from understanding their own experiences (Fricker 2007). I argue that because Fricker misdescribes dominant hermeneutical resources as collective, she fails to locate the ethically bad epistemic practices that maintain gaps in dominant hermeneutical resources even while alternative interpretations are in fact offered by non-dominant discourses. Fricker's analysis of hermeneutical injustice does not account for the possibility that (...) marginalized groups can be silenced relative to dominant discourses without being prevented from understanding or expressing their own social experiences. I suggest that a gap in dominant hermeneutical resources is ambiguous between two kinds of unknowing: hermeneutical injustice suffered by members of marginalized groups, and epistemically and ethically blameworthy ignorance perpetrated by members of dominant groups.

Epistemic decision theory produces arguments with both normative and mathematical premises. I begin by arguing that philosophers should care about whether the mathematical premises (1) are true, (2) are strong, and (3) admit simple proofs. I then discuss a theorem that Briggs and Pettigrew (2020) use as a premise in a novel accuracy-dominance argument for conditionalization. I argue that the theorem and its proof can be improved in a number of ways. First, I present a counterexample that shows that one (...) of the theorem’s claims is false. As a result of this, Briggs and Pettigrew’s argument for conditionalization is unsound. I go on to explore how a sound accuracy-dominance argument for conditionalization might be recovered. In the course of doing this, I prove two new theorems that correct and strengthen the result reported by Briggs and Pettigrew. I show how my results can be combined with various normative premises to produce sound arguments for conditionalization. I also show that my results can be used to support normative conclusions that are stronger than the one that Briggs and Pettigrew’s argument supports. Finally, I show that Briggs and Pettigrew’s proofs can be simplified considerably. (shrink)

Argues that morality can exist without religion, suggests that values and principles of conduct emerge from life, and examines the consequences of moral absolutism.

ABSTRACT According to one widely accepted view, our actions and emotions ought to be proportional to the degree of value present in their objects. Against this proportionality principle, Pettigrove sketches a view according to which the value of some virtuous actions and attitudes derives from the characteristic way of being of the agent herself, and not from any other goods that agent appreciates, pursues, or promotes. Granting Pettigrove’s rejection of the proportionality principle, I raise some questions for his replacement account. (...) I suggest that it is not just the characteristic way of being of an agent who loves and forgives virtuously that explains the goodness of their love and forgiveness, but also the role such virtues play in making possible valuable relationships that are partially constitutive of human flourishing.

Obtaining human genetic samples is vital for many biobank research purposes, yet, the ethics of obtainment seems to many fraught with difficulties. One key issue is consent: it is by many considered ethically vital that consent must be fully informed (at least ideally speaking) in order to be legitimate. In this paper, we argue for a more liberal approach to consent: a donor need not know all the specifics of future uses of the sample. We argue that blanket consent is (...) ethically defensible, and that this is buttressed by considerations of (justified) trust-relations. Given robust institutional oversight, blanket consent is a permissible form of consent in the bio-banking context. (shrink)

In this essay, I reply to critiques of my article “In Defense of Transracialism.” Echoing Chloë Taylor and Lewis Gordon’s remarks on the controversy over my article, I first reflect on the lack of intellectual generosity displayed in response to my paper. In reply to Kris Sealey, I next argue that it is dangerous to hinge the moral acceptability of a particular identity or practice on what she calls a collective co-signing. In reply to Sabrina Hom, I suggest that relying (...) on the language of passing to describe transracialism is potentially misleading. In reply to Tina Botts, I both defend analytic philosophy of race against her multiple criticisms and suggest that Botts’s remarks risk complicity with a form of transphobia that Talia Mae Bettcher calls the Basic Denial of Authenticity. I end by gesturing toward a more inclusive understanding of racial identity. (shrink)

Evolution was not discovered single-handedly, Rebecca Stott argues, contrary to what has become standard lore, but is an idea that emerged over many centuries, advanced by daring individuals across the globe who had the imagination to speculate on nature's extraordinary ways, and who had the courage to articulate such speculations at a time when to do so was often considered heresy.

Proofs are central, and unique, to mathematics. They establish the truth of theorems and provide us with the most secure knowledge we can possess. It is thus perhaps unsurprising that philosophers once thought that the only value proofs have lies in establishing the truth of theorems. However, such a view is inconsistent with mathematical practice. If a proof’s only value is to show a theorem is true, then mathematicians would have no reason to reprove the same theorem in different ways, (...) yet this is a practice they frequently engage in. This suggests that proofs can have a wide variety of values. My purpose in this chapter is to provide a survey of some of them. I will discuss how proofs can have practical value, for example, by helping mathematicians to make new discoveries or learn new mathematical tools, and how they can have abstract value, for example, by being beautiful or explanatory. I will also explore the relationships between different proof values. (shrink)

Emerging from the internationally recognised Theorising Normalcy and the Mundane conference series, the chapters in this book offer wide-ranging critiques of that most pervasive of ideas, 'normal'. In particular, they explore the precarious positions we are presented with and, more often than not, forced into by 'normal', and its operating system, 'normalcy' (Davis, 2010). They are written by activists, students, practitioners and academics and offer related but diverse approaches. Importantly, however, the chapters also ask, what if increasingly precarious encounters with, (...) and positions of, marginality and non-normativity offers us a chance (perhaps the chance) to critically explore the possibilities of 'imagining otherwise'? The book questions the privileged position of 'non-normativity'; in youth and unpacks the expectation of the 'normal' student in both higher and primary education. It uses the position of transable people to push the boundaries of 'disability', interrogates the psycho-emotional disablism of box-ticking bureaucracy and spotlights the 'urge to know' impairment. It draws on cross-movement and cross-disciplinary work around disability to explore topics as diverse as drug use, The Bible and relational autonomy. Finally, and perhaps most controversially, it explores the benefits of (re)instating 'normal'. By paying attention to the opportunities presented amongst the fissures of critique and defiance, this book offers new applications and perspectives for thinking through the most ordinary of ideas, 'normal'.

Should monkeys be used in painful and often deadly infectious disease research that may save many human lives? This is the challenging question that Anne Barnhill, Steven Joffe, and Franklin G. Miller take on in their carefully argued and compelling article “The Ethics of Infection Challenges in Primates.” The authors offer a nuanced and even-handed position that takes philosophical worries about nonhuman primate moral status seriously and still appreciates the very real value of such research for human welfare. Overall, they (...) argue for an extension and revision of the recommendations regarding chimpanzee research offered by the Institute of Medicine in 2011; the practical upshot of their argument would allow for infection challenge research for promising interventions for Ebola and Marburg virus diseases but not for smallpox or the common cold. The IOM recommendations regarding chimpanzee research put in motion an exceptionalist policy for this great ape population. Barnhill and colleagues’ proposal would enlarge the scope of that exceptionalism to embrace NHPs other than great apes. But is such exceptionalism warranted? It is not obvious to me either that the more sophisticated capacities of a species as a whole give it greater ethical protections or that less intellectually or socially sophisticated animals ought to therefore receive less protection when it comes to painful experimental interventions.

This chapter explores two kinds of testimonial trust, what we call ‘evidential trust’ and ‘non-evidential trust’ with the aim of asking how testimonial trust could provide epistemic reasons for belief. We argue that neither evidential nor non-evidential trust can play a distinctive role in providing evidential reasons for belief, but we tentatively propose that non-evidential trust can in some circumstances provide a novel kind of epistemic reason for belief, a reason of epistemic facilitation. The chapter begins with an extensive discussion (...) of standard accounts of both kinds of trust and criticises especially the standard accounts of non-evidential trust. A new account of non-evidential trust is offered that avoids a number of difficulties that plague the standard accounts by rejecting what we call ‘attitude-liability assumptions’. (shrink)

Proposals to modernise fertility law in the UK In November 2023, the Human Fertilisation and Embryology Authority (HFEA) published recommendations 1 for changes to the Human Fertilisation and Embryology Act. 2 The HFEA regulates fertility treatments and embryo research in the UK. The recommendations were informed by a public consultation process during which the HFEA heard from patients, professionals and others with an interest in the regulations. The consultation ran from February - April 2023 and received just over 6800 responses. (...) The recommendations focus on four main areas that the HFEA consider to be in need of modernisation within the Act – patient protection and safety; consent; access to donor information; and future scientific developments and innovation. The Authority proposes that it should be given greater freedom and flexibility to promote patient safety and good practice. For example, through a wider range of regulatory enforcement powers,...

Cheyne and Girard characterize felt presence during sleep paralysis attacks as a pre-hallucinatory expression of a threat-activated vigilance system. While their results may be consistent with this interpretation, they are nonetheless correlational and do not address a parsimonious alternative explanation. This alternative stipulates that FP is a purely spatial, hallucinatory form of a common cognitive phenomenon—social imagery—that is often, but not necessarily, linked with threat and fear and that may induce distress among susceptible individuals. The occurrence of both fearful and (...) non-fearful FPs in a multiplicity of situations other than sleep paralysis attacks supports the notion that FPs are hallucinatory variants of social imagery and that they are not necessarily bound to threat-activated vigilance. Evidence linking FPs with anxiety disorders supports the notion that the distress they evoke may be mediated by a more general affective distress personality factor. To illustrate the predominantly spatial character of FP hallucinations, similarities between FP and phantom limbs are summarized and the possibility that these two phenomena are parallel expressions of a mirror neuron system is considered.

Ch. G. Bardili (1761-1808) ist der Begrunder des rationalen Realismus mit dem Ziel eines von der Materialitat ausgehenden Gottesbeweises. Heute nur noch als von den Zeitgenossen fast einhellig abgelehnter Denker bekannt, bietet sein Schaffen in der enormen Spannbreite von Wissenschaftsreflexionen, Ethik, Philosophiegeschichte und Logik doch ein interessantes, facettenreiches und in seiner Radikalitat anregendes Gesamtkonzept. Dieses Werk erstmals in vollem Umfang zu erschliessen, das ganze System Bardilis in seiner Entwicklung und seinen Inhalten nachzuzeichnen sowie in seinen Grundzugen, die fur die Debatten (...) der Zeit, etwa mit Fichte, Schelling und Reinhold, bedeutsam sind, aufzuweisen, ist die Absicht des vorliegenden Bandes.'Bislang liegt uber Bardili keine nennenswerte Literatur vor. [.] Diese Lucke schliesst nun die vorgelegte Monographie, [.] um so ein Werk vorzustellen, das zwar heute weitgehend in den Hintergrund geruckt oder oft schlicht vergessen ist, das es gleichwohl - wie die Vf. uberzeugend zu zeigen vermag - verdient hat, wieder starkere Beachtung zu finden, weil es zu zentralen Fragestellungen, wie sie im Bereich der klassischen deutschen Philosophie wichtig und bestimmend geworden sind, eine haufig zweifellos eigenwillige, aber trotzdem wegen seines hohen Grades an Originalitat und seiner radikalen, wenn auch bisweilen exzentrisch anmutenden, Alternativstellung bedenkenswerte Anstosse bietet. [.] Insgesamt leistet die Vf. mit ihrer Monographie Hervorragendes und Vorbildliches: Sie zeichnet den Denkweg und das System Bardilis in ihrer Entwicklung und ihren Inhalten nach. Die wesentlichen Grundzuge, die sich fur die Debatten, Streitgesprache und [.] philosophischen Konstellationen der Zeit als so bedeutsam erwiesen, werden pragnant aufgewiesen und mit denkerisch hochster Souveranitat durchdrungen.'

Analyzing two key figures in Elif Shafak’s novel The Island of Missing Trees—a schoolgirl’s scream and a narrating fig tree—this essay analyzes the intersection between susceptibility and resilience, particularly as these terms are developed in psychology, trauma studies, and ecology. I argue that the novel’s resonant scream critiques the discourse of psychological resilience on multiple counts: its inadequacy as a response to complex trauma, its focus on autonomous individuals, its assumption that responsibility for resilience rests on victims rather than perpetrators (...) of harm, its construction of a “resistance imperative” and its disavowal of the inequalities in access to resilience-building resources. By contrast, the novel’s fig tree, I contend, exemplifies an ecological model of resilience rooted in a recognition of the interdependence of the multiple and diverse organisms that comprise an ecosystem, and of susceptibility as an advantageous suite of capacities that are crucial to resilience. These contrasting conceptions of resilience lead me to advocate for a politics of susceptibility, an eco-psychosocial politics based on the recognition that individuals cannot become resilient on their own, through their own volition, intention, or “self-efficacy”, and that focuses instead on building systemic and sustainable forms of resilience inclusive of the diverse subjects that comprise a community, society or ecosystem; that, rather than fetishizing independence, liberty and rights, fortifies interdependence and reinforces mutual responsibilities; and that rather than exploiting susceptibility as a weakness, nurtures it as the soul of resilience itself.

This paper applies Karl Jaspers’ and Martin Heidegger’s accounts of transcendence to their descriptions of Van Gogh’s art. I will contrast Jaspers’ more vertical account of immanent transcendence to Heidegger’s horizontal one. This difference between their separate understandings of transcendence manifests itself in their estimations of the significance of Van Gogh’s art. Using phenomenology to understand Van Gogh’s art in light of immanent transcendence, moreover, illuminates a new understanding of transcendence as the ‘beyond’ that is always already here in the (...) immanent and reveals the ability of an object to point beyond itself. Both of these concepts are at work in Van Gogh’s art as well as modern art in general as the expansion of reality through new sight. Immanent transcendence and Van Gogh’s art are different but interconnected ways of rethinking experience beyond the limits of positivism and the myth of the given. Van Gogh’s art thus embodies a sensible world transformed. In particular, Van Gogh’s landscapes and still life series suggest the inexhaustibility of the things we so often overlook in our everyday experience. (shrink)

Among all their sensations, agents need to distinguish between those caused by themselves and those caused by external causes. The ability to infer agency is particularly challenging under conditions of uncertainty. Within the predictive processing framework, this should happen through active control of prediction error that closes the action-perception loop. Here we use a novel, temporally-sensitive, behavioural proxy for prediction error to show that it is minimised most quickly when volatility is high and when participants report agency, regardless of the (...) accuracy of the judgement. We demonstrate broad effects of uncertainty on accuracy of agency judgements, movement, policy selection, and hypothesis switching. Measuring autism traits, we find differences in policy selection, sensitivity to uncertainty and hypothesis switching despite no difference in overall accuracy. (shrink)

In this chapter, I argue that one can articulate a historically attuned and analytically rich model for understanding jazz in its various inflections. That is, on the one hand, such a model permits us to affirm jazz as a historically conditioned, dynamic hybridity. On the other hand, to acknowledge jazz’s open and multiple character in no way negates our ability to identify discernible features of various styles and aesthetic traditions. Additionally, my model affirms the sociopolitical, legal (Jim Crow and copyright (...) laws), and economic structures that shaped jazz. Consequently, my articulation of bebop as an inflection of Afromodernism highlights the sociopolitical, and highly racialized context in which this music was created. Without a recognition of the sociopolitical import of bebop, one’s understanding of the music is impoverished, as one fails to grasp the strategic uses to which the music and discourses about the music were put.

Traditionally, discussions of moral participation – and in particular moral agency – have focused on fully formed human actors. There has been some interest in the development of morality in humans, as well as interest in cultural differences when it comes to moral practices, commitments, and actions. However, until relatively recently, there has been little focus on the possibility that nonhuman animals have any role to play in morality, save being the objects of moral concern. Moreover, when nonhuman cases are (...) considered as evidence of moral agency or subjecthood, there has been an anthropocentric tendency to focus on those behaviors that inform our attributions of moral agency to humans. For example, some argue that the ability to evaluate the principles upon which a moral norm is grounded is required for full moral agency. Certainly, if a moral agent must understand what makes an action right or wrong, then most nonhuman animals would not qualify (and perhaps some humans too). However, if we are to understand the evolution of moral psychology and moral practice, we need to turn our attention to the foundations of full moral agency. We must first pay attention to the more broadly normative practices of other animals. Here, we begin that project by considering evidence that great apes and cetaceans participate in normative practices. (shrink)

Medical records are documents of tremendous social importance. They have been the subject of much medical and sociological research, in particular regarding validity, accessibility and readability. This paper uses Conversation Analysis to add an aspect to the understanding of medical records that has been missing so far, namely how medical records are produced as interactional accomplishments; specifically, how hospital staff members during meetings conversationally negotiate and reach conclusions, treatment recommendations, and other types of consequential decisions. The process involves four steps: (...) assessing patients, interpreting implications, drawing conclusions, and dictating conclusions on tape. The key finding is that participants throughout the process orient towards a need for consensus, whilst at the same time acknowledging the doctors’ interactional leading roles. This insight can enhance our understanding of medical records in hospital settings as constructed and negotiated realities. (shrink)

At the heart of any theoretical problem of justice lies the problem of motivation: Even if we could conceive of a way to develop a comprehensive system of just laws, and even if we could rationally believe in the justice of these laws, how could we ever ensure that we—or anyone else—would be motivated to abide by them? By unearthing how the problem of motivation sways canonical discussions of justice, the article brings forth intrinsic similarities and differences in these discussions (...) that are often overlooked in the literature. In particular, the article highlights intrinsic similarities in the analysis of the concept of justice in two central works that belong to the continental and the analytic tradition respectively and are otherwise rarely discussed together: Hegel’s Outlines of the Philosophy of Right and Rawls’s Theory of Justice.

The past decade has seen an explosion of work on the history of the human sciences during the Cold War. This work, however, does not engage with one of the leading human sciences of the period: linguistics. This article begins to rectify this knowledge gap by investigating the influence of linguistics and its concept of study, language, on American public, political and intellectual life during the postwar and early Cold War years. I show that language emerged in three frameworks in (...) this period: language as tool, language as weapon, and language as knowledge. As America stepped onto the international stage, language and linguistics were at the forefront: the military poured millions of dollars into machine translation, American diplomats were required to master scores of foreign languages, and schoolchildren were exposed to language-learning on a scale never before seen in the United States. Together, I argue, language and linguistics formed a critical part of the rise of American leadership in the new world order — one that provided communities as dispersed as the military, the diplomatic corps, scientists and language teachers with a powerful way of tackling the problems they faced. To date, linguistics has not been integrated into the broader framework of Cold War human sciences. In this article, I aim to bring both language, as concept, and linguistics, as discipline, into this framework. In doing so, I pave the way for future work on the history of linguistics as a human science. (shrink)

Public reason liberalism strives to accommodate as broad an array of viewpoints as possible. Some people are selective science skeptics, meaning that they disagree with parts of mainstream science. Of special interest for this paper are climate deniers, who disagree with the mainstream consensus views of climate science. This creates a problem for public reason: on the one hand, public reason wants to avoid basing rules and policies on controversial principles, values, and so on. On the other hand, there are (...) citizens whom we cannot outright call irrational who are skeptical about central tenets of climate science. This seems to imply that public reason cannot base policies on the robust findings of climate science because these findings are controversial among the citizenry. But we have strong reasons to base our policies vis-à-vis climate change on the robust findings of climate science. How should we proceed? (shrink)

Human Rights Education (HRE) has traditionally been articulated in terms of cultivating better citizens or world citizens. The main preoccupation in this strand of HRE has been that of bridging a gap between universal notions of a human rights subject and the actual locality and particular narratives in which students are enmeshed. This preoccupation has focused on ‘learning about the other’ in order to improve relations between plural ‘others’ and ‘us’ and reflects educational aims of national identity politics in citizenship (...) education. The article explores the learning of human rights through narratives in relations, drawing on Hannah Arendt and Sharon Todd. For this re-thinking of relations in learning human rights, the article argues that HRE needs to address both competing historical narratives on the drafting of the Universal Declaration on Human Rights (UDHR) as well as unique life narratives of learners.

Mathematicians judge proofs to possess, or lack, a variety of different qualities, including, for example, explanatory power, depth, purity, beauty and fit. Philosophers of mathematical practice have begun to investigate the nature of such qualities. However, mathematicians frequently draw attention to another desirable proof quality: being motivated. Intuitively, motivated proofs contain no "puzzling" steps, but they have received little further analysis. In this paper, I begin a philosophical investigation into motivated proofs. I suggest that a proof is motivated if and (...) only if mathematicians can identify (i) the tasks each step is intended to perform; and (ii) where each step could have reasonably come from. I argue that motivated proofs promote understanding, convey new mathematical resources and stimulate new discoveries. They thus have significant epistemic benefits and directly contribute to the efficient dissemination and advancement of mathematical knowledge. Given their benefits, I also discuss the more practical matter of how we can produce motivated proofs. Finally I consider the relationship between motivated proofs and proofs which are explanatory, beautiful and fitting. (shrink)

The claim that we have a moral obligation, where a choice can be made, to bring to birth the 'best' child possible, has been highly controversial for a number of decades. More recently Savulescu has labelled this claim the Principle of Procreative Beneficence. It has been argued that this Principle is problematic in both its reasoning and its implications, most notably in that it places lower moral value on the disabled. Relentless criticism of this proposed moral obligation, however, has been (...) unable, thus far, to discredit this Principle convincingly and as a result its influence shows no sign of abating. I will argue that while criticisms of the implications and detail of the reasoning behind it are well founded, they are unlikely to produce an argument that will ultimately discredit the obligation that the Principle of Procreative Beneficence represents. I believe that what is needed finally and convincingly to reveal the fallacy of this Principle is a critique of its ultimate theoretical foundation, the notion of impersonal harm. In this paper I argue that while the notion of impersonal harm is intuitively very appealing, its plausibility is based entirely on this intuitive appeal and not on sound moral reasoning. I show that there is another plausible explanation for our intuitive response and I believe that this, in conjunction with the other theoretical criticisms that I and others have levelled at this Principle, shows that the Principle of Procreative Beneficence should be rejected.
