This target article considers the ethical implications of providing prenatal diagnosis (PND) and antenatal screening services to detect fetal abnormalities in jurisdictions that prohibit abortion for these conditions. This unusual health policy context is common in the Latin American region. Congenital conditions are often untreated or under-treated in developing countries due to limited health resources, leading many women/couples to prefer termination of affected pregnancies. Three potential harms derive from the provision of PND in the absence of legal and (...) safe abortion for these conditions: psychological distress, unjust distribution of burdens between socio-economic classes, and financial burdens for families and society. We present Iran as a comparative case study where recognition of these ethical issues has led to the liberalization of abortion laws for fetuses with thalassemia. We argue that physicians, geneticists and policymakers have an ethical and professional duty of care to advocate for change in order to ameliorate these harms. (shrink)

The goals of vascular composite allotransplantation for hand are to maximize functional status and psychosocial wellbeing and to improve quality of life. Candidates are carefully vetted by transplant programs through an extensive evaluation process to exclude those patients with contraindications and to select those that are most likely to attain functional or quality of life benefit from transplant. Patient choice for any treatment, however, requires that candidates be able to understand the risks, benefits, and alternatives before choosing to proceed. This (...) study aimed to understand patients’ knowledge and perceptions about treatment options for hand loss, including hand transplant. This study will be used to inform a standardized education approach and develop conversation aids for use by clinicians and patients throughout the treatment decision process. Ten individuals who had experienced hand amputation or had congenital limb loss were interviewed to better understand previous and current decisions about treatment, experiences in adjusting to their treatment, and perceptions about hand VCA. From this qualitative interview data, four findings emerged: knowledge and education around VCA as a treatment option; adaptation of individuals with limb loss; fear of risk associated with transplantation; issues of aging and overuse injuries to existing limbs. Results suggests that there is opportunity for expanding education about all treatment options for patients with new loss, long-term loss, and congenital limb loss. Establishing a baseline of knowledge about all options–prosthetics, rehabilitative strategies, and VCA—can help patients evaluate their values and goals of treatment. Issues associated with aging, including overuse and injury, and adaptability over the life course should be included in considerations about treatment choices. Data indicate the need for routinely assessing patient preferences about treatment choice so patients can plan for their future as they adapt and age and as technology for treatments change. To assure that thorough information is provided for current and future decision-making, education about treatment choices and selection procedures for VCA should be standardized. (shrink)

A woman with congenital absence of a uterus applied for participation in a clinical trial for uterus transplantation. She was married to a woman who had the potential to carry a child without the need for aggressive medical intervention. Thus, the question arose regarding whether the infertile partner should be considered for uterus transplantation. In this article we discuss the ethical issues with uterus transplantation for a member of a same-sex couple, whose partner could carry a pregnancy. We (...) review the medical criteria for uterus transplantation, discuss the additional options for parenthood in same-sex couples, examine how to determine if this meets the criteria of just distribution of uterus grafts, and ultimately argue that the value of gestation is at the level of the individual rather than the couple.

Recent studies in developmental psychology have found evidence to suggest that there exists an innate system that accounts for the possibilities of early infant imitation and the existence of phantom limbs in cases of congenital absence of limbs. These results challenge traditional assumptions about the status and development of the body schema and body image, and about the nature of the translation process between perceptual experience and motor ability.

Analysing ten interviews with women diagnosed with and treated for congenital absence of the vagina, this article theorises the notion of ideal (hetero)relational normality. It explores how women in my case study negotiate, relate to and challenge this notion and examines the normative and bodily work for which it calls. The article specifically underscores the corporeal dimension of (hetero)relational normality. I argue that this notion of normality shapes the bodies of the women through medical interventions, while concurrently being (...) reinforced through the corporeal shapings that the women undergo. These corporeal shapings consolidate enacted norms concerning heterosexuality and form understandings of female and male bodies. The analysis also reveals how these women nevertheless find ways to re-negotiate and question the notion of ideal (hetero)relational normality and its intertwinement with medical practice. The article contributes both to the critical examination of genital surgery and to feminist discussions of how to critically examine heterosexuality without rejecting it. Furthermore, it provides a deeper understanding of how medical interventions designed to create a vagina, or dilate a vagina considered ‘too small’, are made meaningful by the women affected.

It is widely accepted that embodiment is crucial for any self-aware agent. What is less obvious is whether the body has to be real, or whether a virtual body will do. In that case the notion of embodiment would be so attenuated as to be almost indistinguishable from disembodiment. In this article I concentrate on the notion of embodiment in human agents. Could we be disembodied, having no real body, as brains-in-a-vat with only a virtual body? Thought experiments alone will (...) not suffice to answer this Cartesian question. I will draw on both philosophical arguments and empirical data on phantom phenomena. My argument will proceed in three steps. Firstly I will show that phantom phenomena provide a prima facie argument that real embodiment is not necessary for a human being. Secondly I will give a philosophical argument that real movement must precede the intention to move and to act. Agents must at least have had real bodies once. Empirical data seems to bear this out. Finally, however, I will show that a small number of aplasic phantom phenomena undermines this last argument. Most people must have had a real body. But for some people a partly virtual, unreal, phantom body seems to suffice. Yet though there is thus no knockdown argument that we could not be brains-in-a-vat, we still have good reasons to suppose that embodiment must be real, and not virtual. (shrink)

The repeatedly noted absence of case-reports of individuals with schizophrenia and congenital/early developed blindness has led several authors to argue that the latter can confer protective effects against the former. In this work, we present a number of relevant case-reports from different syndromes that show comorbidity of congenital and early blindness with schizophrenia. On the basis of these reports, we argue that a distinction between different types of blindness in terms of the origin of the visual deficit, (...) cortical or peripheral, is crucial for understanding the observed patterns of comorbidity. We discuss the genetic underpinnings and the brain structures involved in schizophrenia and blindness, with insights from language processing, laying emphasis on the three structures that particularly stand out: the occipital cortex, the lateral geniculate nucleus and the pulvinar. Last, we build on previous literature on the nature of the protective effects in order to offer novel insights into the nature of the protection mechanism from the perspective of the brain structures involved in each type of blindness.

Infertility specialists may be confronted with the ethical dilemma of whether to disclose misattributed paternity (MP). Physicians should be prepared for instances when an assumed father’s evaluation reveals a condition known for lifelong infertility, for example, congenital bilateral absence of vas deferens (CBAVD). When there is doubt regarding a patient’s comprehension of his diagnosis, physicians must consider whether further disclosure is warranted. This article describes a case of MP with ethics analysis that concludes that limited nondisclosure is most (...) consistent with a physician’s principled duties to inform, to respect patients’ autonomy, and to employ nonmaleficence (including the avoidance of psychosocial harms).

This book breaks new ground in our understanding of how we perceive and represent the space around us - one of the central topics in cognitive psychology. It presents a new view of development and spatial cognition by reversing the usual focus on vision and examining the evidence on representation in the total absence of vision without specific brain damage. Findings from the author's work with congenitally totally blind and with sighted children, together with studies from a wide variety (...) of other areas, are set in the context of intersensory and spatial development. Touch and movement are considered as converging sources of reference information with and without vision. The findings have important implications for future work in many fields, particularly developmental pscychology; cognition, cognitive neuroscience and visual handicap, and make this new work essential reading for students and researchers in these fields.

Este artigo propõe-se a refletir sobre a construção do Eu de crianças com cegueira congênita a partir da teoria winnicottiana do amadurecimento. Para Winnicott, a natureza humana é uma questão de psique-soma em constante interação; o ser humano é essencialmente psicossomático, sendo o corpo o primeiro a chegar e a elaboração imaginativa das funções corpóreas o elemento constitutivo e enriquecedor da vida psíquica. Essa concepção da natureza humana parece ser a mais esclarecedora para a compreensão do desenvolvimento e da construção (...) do eu das crianças com cegueira congênita; crianças que chegam ao mundo com uma constituição orgânica significativamente diferente, que as conduzem por caminhos peculiares em seu processo de percepção e amadurecimento. Muitas dificuldades são apontadas na descrição do desenvolvimento dessas crianças: passividade de ego, ausência de interesse por objetos, atrasos na aquisição de capacidades, desinteresse por brincadeiras e verbalismo. Comportamentos considerados semelhantes aos de crianças autistas. Acreditamos que, a partir da teoria winnicottiana do desenvolvimento, muitas dessas vicissitudes podem ser compreendidas e alguns procedimentos terapêuticos indicados.This article proposes a reflection upon the ego development of children with congenital blindness through maturation theory. For Winnicott the human nature is a matter of psyche-some in constant interaction, the human being is essentially psychosomatic, in which the body is the first to arrive and the imaginative elaboration of the body functions are the elements that constitute and enrich the psychic life. This conception of the human nature seems to be the most clarifying for the comprehension of the development and the self constitution of the children with congenital blindness; children who arrive into the world with a significantly different organic constitution, which conducts them through a peculiar path in their process of perception and maturity. Many difficulties are pointed out on the description of the development of these children: passivity of the ego, absence of interest for objects, delay on the acquisition of abilities, disinterest for children's play, verbalism. Behaviors similar to those of autistic children. We believe that through Winnicott's developmental theory a lot of these vicissitudes can be comprehended and some therapeutic procedures can be indicated. (shrink)

Anecdotal reports obtained from three individuals with prosopagnosia, all of whom have participated in an investigation, capture the essence of their impairment. This article focuses on the contrast between two prominent forms of prosopagnosia, one of which results from an acquired brain insult in an otherwise premorbidly normal individual and a second which appears to be lifelong and occurs in the absence of any obvious brain damage, at least as evident on conventional brain imaging. It reviews two central issues: (...) the first concerns the similarities and differences in the psychological representations of faces in acquired prosopagnosia and congenital prosopagnosia, and the second concerns the nature of the underlying neural representations of faces in these two populations. Some well-established overlapping behavioral characteristics are identified. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Virtues, Obligations, and the Prophetic VisionRoy Branson (bio)Ethics at its best is only bad poetry—that is, it seeks to help us see whatwe see every day but fail to see rightly...If ethicists had talent, they might be poets,but in the absence of talent, they try tomake their clanking conceptual anddiscursive chains do the work of art.—Stanley HauerwasThe speaker was so severely bent over that his congenitally deformed back (...) had to be supported. He was a young Ph.D. in history. We were some 50 physicians, lawyers, health care administrators, and ethicists studying the ethics of organ transplants. Before he arrived, the conference had discussed different understandings of equal access and the nuances of federal policies governing organ transplant distribution. 1 In his lecture, our guest matter-of-factly described his own condition. He then pointed out that not only in ancient civilization but in American history as well, the disabled had been killed just because they were disabled. Indeed, even now, he said, they were not being allowed to live.In the question and answer session, he was immediately challenged by nationally prominent transplant surgeons. He responded by asking the surgeons: If two people could avoid death and anticipate significantly prolonged life from receiving an organ transplant and the only difference between them was that one was disabled and the other not, who would receive the life-saving transplant? The surgeons’ initial, spirited defense of excluding the significantly disabled person died down as they began to realize that, as far as they were concerned anyway, they might not have allowed the lecturer to live. They were stunned by the realization that they had not felt the disabled were fully persons. In the silences between their sentences, the participants sensed that they had passed beyond the discussion of economic, medical, and legal terms to glimpse new horizons of responsibility. [End Page 361]The conference was experiencing the truth of William F. May’s claim that moral quandaries must be placed within “a fresh and liberating vision of the world;” within “metaphysical horizons” (May 1983, pp. 15, 19).Pastoral VirtuesIn the late sixties, André Hellegers, the dynamic physician and Catholic layman who founded the Kennedy Institute of Ethics and who claimed that he had invented the word bioethics, focused bioethics elsewhere—on virtue. “As the caring branches of medicine were gradually pushed aside by the curing ones,” Hellegers said, “there seemed to be less use for the Christian virtues.” We must, he declared, “recapture the Christian virtues of care” (cited in McCormick 1985, p. 111). In a subsequent essay on the conceptual foundation of bioethics, Hellegers, writing with Albert Jonsen, did not invoke the word pastor, but he did argue that the codes drawn up for the ethical practice of medicine were, among other things, guides for the cure of physicians’ souls (Jonsen and Hellegers 1976, pp. 35–36).In 1969, at the same time that André Hellegers was in the process of establishing the Kennedy Institute, Edmund Pellegrino, then a medical school dean, led in the founding of humanities programs within American medical schools. Pellegrino, like Hellegers, a physician and Catholic layman, also focused on virtue. Obligations are not irrelevant for Pellegrino, but in biomedical ethics “one starts always with one’s commitment to be a certain kind of person and then approaches clinical quandaries, conflicts of values, and patient interests as a good person ought” (Pellegrino 1988, p. 123). Pellegrino knows that the classical and Christian tradition of Aristotle and Aquinas, a tradition with which he identifies, is concerned with the whole gamut of ethics. But for Pellegrino, that tradition teaches that “no matter to what depths a society may fall, virtuous persons will always be the beacons that light the way back to moral sensitivity” (p. 123). He freely acknowledges that “a virtue-based ethics is inherently elitist, in the best sense, because its adherents demand more of themselves than does the prevailing morality” (p. 123).Hellegers and Pellegrino added to the need of physicians acquiring professional skills their responsibility to become the embodiment of the moral ideal in the patient-physician relationship by caring for the patient...

Arthrogryposis multiplex congenita (AMC) is a heterogeneous syndrome where multiple joints have reduced range of motion due to contracture formation prior to birth. A common cause of AMC is reduced embryonic movement in utero. This reduction in embryonic movement can perturb molecular mechanisms and signaling pathways involved in the formation of joints during development. The absence of mechanical stimuli can impair joint cavitation, resulting in joint fusion, and ultimately eliminate function. In turn, mechanical stimuli are critical for proper joint (...) formation during development and for mitigating AMC. Studies in experimental animal models have provided a greater understanding on the molecular pathophysiology of congenital contracture formation as a consequence of embryonic immobilization. Elucidation of how the mechanical signaling environment is transduced to initiate a biological response will be necessary to gain a deeper understanding of how mechanical stimuli are intertwined in the molecular regulation of joint development.

Vigil suggests that expressed emotions are inherently learned and triggered in social contexts. A strict reading of this account is not consistent with the findings that individuals, even those who are congenitally blind, do express emotions in the absence of an audience. Rather, grounded cognition suggests that facial expressions might also be an embodied support used to represent emotional information.

L'une des tâches de la philosophie de la biologie contemporaine consiste à rechercher les conditions d'un usage des énoncés fonctionnels dont serait éliminée toute trace de causalité inversée ou d'interprétation mentaliste. Parmi les spécifications de l'idée d'un lien entre fonction et adaptation, la théorie de Millikan est remarquable en ceci qu'elle rend compte du divorce possible entre attribution légitime d'une fonction et absence de l'activité fonctionnelle correspondante, comme dans les cas de maladie ou d'atrophie congénitale. On peut montrer que (...) la distinction essentielle entre causes et moyens peut être comprise à partir d'une référence à l'opposition entre explication en termes de développement et explication en termes de sélection, à condition de reconnoître toute la portée de cette dernière. One aim of contemporary philosophy of biology is to secure a use of functional statements in which there would be no implication of reversed causation or anthropomorphic interpretation. Among the recent alternatives, Millikan's theory is most notable for the way it allows to explain the possible divorce between legitimate functional ascriptions and lack of corresponding functional activity, as in disease or congenital atrophy cases. It is argued that the crucial distinction between causes and means can be better understood with a reference to the contrast between developmental and selectional explanations. (shrink)

Experiences of absence are common in everyday life, but have received little philosophical attention until recently, when two positions regarding the nature of such experiences surfaced in the literature. According to the Perceptual View, experiences of absence are perceptual in nature. This is denied by the Surprise-Based View, according to which experiences of absence belong together with cases of surprise. In this paper, I show that there is a kind of experience of absence—which I call frustrating (...) absences—that has been overlooked by the Perceptual View and by the Surprise Based-View and that cannot be adequately explained by them. I offer an alternative account to deal with frustrating absences, one according to which experiencing frustrating absences is a matter of subjects having desires for something to be present frustrated by the world. Finally, I argue that there may well be different kinds of experiences of absence. (shrink)

Following extensive examination of published and unpublished materials, we provide a history of the use of dexamethasone in pregnant women at risk of carrying a female fetus affected by congenital adrenal hyperplasia (CAH). This intervention has been aimed at preventing development of ambiguous genitalia, the urogenital sinus, tomboyism, and lesbianism. We map out ethical problems in this history, including: misleading promotion to physicians and CAH-affected families; de facto experimentation without the necessary protections of approved research; troubling parallels to the (...) history of prenatal use of diethylstilbestrol (DES); and the use of medicine and public monies to attempt prevention of benign behavioral sex variations. Critical attention is directed at recent investigations by the U.S. Food and Drug Administration (FDA) and Office of Human Research Protections (OHRP); we argue that the weak and unsupported conclusions of these investigations indicate major gaps in the systems meant to protect subjects of high-risk medical research.

This article is the first indepth ethical analysis of empirical studies that support the claim that children born without major parts of their cerebral cortex are capable of conscious experiences and have a rudimentary capacity for agency. Congenitally decorticate children have commonly been classified as persistently vegetative, with serious consequences for their well-being and opportunities to flourish. The paper begins with an explication of the rights-based normative framework of the argument, including conceptual analysis of the terms ‘agency’, ‘potentiality for agency’ (...) and ‘gradual approach of agency’. It critically examines Alan Gewirth’s account of the criteria for being a rights bearer and principles for settling rights conflicts between agents and potential agents. It then applies the rights-based normative framework to the ethical challenges associated with care for congenitally decorticate children. It argues that recent empirical studies support the claim that the concepts ‘potential for agency’ and ‘capacity for rudimentary agency’ apply to children who are born without major parts of their cerebral cortex. The article finally discusses important medical ethical implications of these results. It specifically focuses on congenitally decorticate children’s preparatory rights to a stimulating intellectual and social environment. (shrink)

Chagas disease or American trypanosomiasis is an important health problem in Latin America. Due to the mobility of Latin American population around the world, countries without vector presence started to report disease cases. We developed a deterministic compartmental model in order to gain insights into the disease dynamics in a scenario without vector presence, considering congenital transmission and transmission by blood transfusion. The model was used to evaluate the epidemiological effect of control measures. It was applied to demographic data (...) from Spain and sensitivity analysis was performed on model parameters associated with control strategies. (shrink)

I take the phrase ‘congenital transcendentalism’ from Santayana who defined it as ‘the spontaneous feeling that life is a dream’. ‘The loneliness which is the truth about things’ is a phrase of Virginia Woolf's. The thesis I will advance is that many expressions of doubt or denial of the shareable world are self-misunderstood manifestations of the state indicated by Woolf's expression. But the loneliness of which Woolf speaks must not be construed as the kind of loneliness which can be (...) assuaged by family, friends, lovers or company. Nor is it the loneliness which a convinced solipsist might experience. It is rather the loneliness of ‘that “I” and that “life of mine'” which is ‘untouched whichever way the issue is decided whether the world is or is not’. (shrink)

In this paper, I consider the implications of grief for philosophical theorising about absence experience. I argue that whilst some absence experiences that occur in grief might be explained by extant philosophical accounts of absence experience, others need different treatment. I propose that grieving subjects' descriptions of feeling as if the world seems empty or a part of them seems missing can be understood as referring to a distinctive type of absence experience. In these profound (...) class='Hi'>absence experiences, I will argue, the absence of a person as a condition on various possibilities is made manifest in the structure of experience over time. Thus, by paying close attention to grief, we can see that even accounts of absence experience that are presented as in competition with one another may not be so, and that to explain all kinds of absence experience we sometimes need to appeal to something overlooked in other accounts, and which is neither straightforwardly perceptual or cognitive. I also suggest that we would have good reason to take such experiences to be part of and not merely psychological effects of grief. (shrink)

Often when one omits to do a certain thing, there's no action that is one's omission; one's omission, it seems, is an absence of any action of some type. This paper advances the view that an absence of an action--and, in general, any absence--is nothing at all: there is nothing that is an absence. Nevertheless, it can result from prior events that one omits to do a certain thing, and there can be results of the fact (...) that one omits to do something. This is so even if absences cannot be causes or causal effects. (shrink)

Phenomenology has contributed to healthcare by providing resources for understanding the lived experience of the patient and their situation. But within a burgeoning literature on the characteristic features of illness, there has not yet been an account appropriate to describe congenital illnesses: conditions which are present from birth and cause suffering or medical threat to their bearers. Congenital illness sits uncomfortably with standard accounts in phenomenology of illness, in which concepts such as loss, doubt, alienation and unhomelikeness presuppose (...) prior health. These accounts reflect, in different ways, Maurice Merleau-Ponty’s assumption that the ways of living of the ill contain allusions to fundamental, healthy functions. The originality of congenital illness complicates this assumption and demands its own original phenomenology. In this paper, I sketch my personal experience living with a single-ventricle heart condition. While some of this story may reflect my own idiosyncratic experience, I hope that much of it will resonate with the congenital illness experience. I argue that the phenomenological literature on illness, grounded in the notion of loss, does not describe the congenital illness experience. I show how a number of other patient-centred theories of health and illness which have been influential on phenomenology can and cannot elucidate congenital illness. In particular, I consider Georges Canguilhem’s account of the normal and the pathological; debates in disability; and the notion of illness as biographical disruption. I show that congenital illness results in the preadmission of its patients to a paradoxical logic of medical palliation, one product of which is existential maturity. (shrink)

Intuitively, we often see absences. For example, if someone steals your laptop at a café, you may see its absence from your table. However, absence perception presents a paradox. On prevailing models of perception, we see only present objects and scenes (Marr, Gibson, Dretske). So, we cannot literally see something that is not present. This suggests that we never literally perceive absences; instead, we come to believe that something is absent cognitively on the basis of what we perceive. (...) But this cognitive explanation does not do justice to the phenomenology. Many experiences of absence possess immediate, perceptual qualities. One may further argue that the ability to detect certain absences confers strong adaptive advantage and therefore must be as primitive and fundamental to humans as seeing positive things. I argue that we can literally see absences; in addition to representing objects, perception represents absences of objects. I present a model of seeing absence based on visual expectations and a visual matching process. The phenomenon of seeing absence can thus serve as an adequacy-test for a theory of perceptual content. If experiences of absence are possible, then we have another reason (following Siegel) to reject the view that perceptual content is restricted to colors and shapes. Furthermore, if the proposed account is correct, then we have grounds for dissociating seeing absence from other imagery-based phenomena termed “perceptual presence-in-absence” (Noë, Macpherson).

To test if dreams contain remote or never-experienced motor skills, we collected during 6 weeks dream reports from 15 paraplegics and 15 healthy subjects. In 9/10 subjects with spinal cord injury and in 5/5 with congenital paraplegia, voluntary leg movements were reported during dream, including feelings of walking , running , dancing , standing up , bicycling , and practicing sports . Paraplegia patients experienced walking dreams just as often as controls . There was no correlation between the frequency (...) of walking dreams and the duration of paraplegia. In contrast, patients were rarely paraplegic in dreams. Subjects who had never walked or stopped walking 4–64 years prior to this study still experience walking in their dreams, suggesting that a cerebral walking program, either genetic or more probably developed via mirror neurons is reactivated during sleep.

I focus on token, deterministic causal claims as they feature in causal explanations. Adequately handling absences is difficult for most causal theories, including theories of causal explanation. Yet so is adequately handling cases of late preemption. The best account of absence-causal claims as they appear in causal explanations is Jonathan Schaffer's quaternary, contrastive account. Yet Schaffer's account cannot handle preemption. The account that best handles late preemption is James Woodward's interventionist account. Yet Woodward's account is inadequate when it comes (...) to absences. I propose an account that handles both absences and preemption by transposing Schaffer's account into an interventionist framework. (shrink)

“Absence of evidence isn’t evidence of absence” is a slogan that is popular among scientists and nonscientists alike. This article assesses its truth by using a probabilistic tool, the Law of Likelihood. Qualitative questions (“Is E evidence about H ?”) and quantitative questions (“How much evidence does E provide about H ?”) are both considered. The article discusses the example of fossil intermediates. If finding a fossil that is phenotypically intermediate between two extant species provides evidence that those (...) species have a common ancestor, does failing to find such a fossil constitute evidence that there was no common ancestor? Or should the failure merely be chalked up to the imperfection of the fossil record? The transitivity of the evidence relation in simple causal chains provides a broader context, which leads to discussion of the fine-tuning argument, the anthropic principle, and observation selection effects.

Absences, i.e., agential omissions and forbearances, but also ‘natural’ negative states and events beyond the sphere of human agency, seem to be part and parcel of the real world. Yet, it is exactly the putative reality of absences that strikes many philosophers as utterly mysterious, if not entirely unintelligible. As a promising approach towards solving the problem of real absences, I wish to explore the idea that absences are latent potentialities. To this end, I shall investigate what potentialities are, what (...) kinds of potentiality exist, and what it means for a potentiality to remain latent. I will also discuss whether the framework of latent potentiality is able to meet the extensional constraints imposed on the theory of absences by our intuitions about the reach of negative acts and events, i.e., whether latent potentialities can account for all real absences.

Imagine that in entering a café, you are struck by the absence of Pierre, with whom you have an appointment. Or imagine that you realize that your keys are missing because they are not hanging from the usual ring-holder. What is the nature of these absence experiences?

We (...) criticize and reject the perceptual interpretation of absence experiences but we also reject the cognitive view which reduces them to beliefs. We propose an intermediary, metacognitive account according to which absence experiences belong to a specific kind of affective experience, involving the feeling of surprise. (shrink)

Au-delà de la technicité grammaticale que créent le système d’article et l’absence d’article (...) au sein du groupe nominal, cette étude permet de repenser la nécessité noologique et phénoménologique de cette classe de mot bien particulière.

In this paper, I argue that subvenient bases of natural kinds and also of thoughts, must be ocnstrued as involving absences.

For the framework of event causation—i.e. the framework according to which causation is a relation between events—absences or omissions pose a problem. Absences, it is generally agreed, are not events; so, under the framework of event causation, they cannot be causally related. But, as a matter of fact, absences are often taken to be causes or effects. The problem of absence causation is thus how to make sense of causation that apparently involves absences as causes or effects. In an (...) influential paper, Helen Beebee offers a partial solution to the problem by giving an account of causation by absence. I argue that Beebee's account can be extended to cover causation of absence as well. More importantly, I argue that the extended Beebeeian account calls for a major modification to David Lewis's theory of causal explanation, usually taken as standard.

Age at marriage and age at first birth are compared across women who experienced different father presence/absence conditions as children. Survival analyses show that daughters of fathers who divorced their mothers or deserted their families have consistently younger ages at marriage and first birth than other women. In contrast, daughters whose fathers were labor migrants (...) have consistently older ages at marriage and first birth. Daughters whose fathers died when they were children show older ages at marriage and first birth than women with divorced/deserted fathers and women with fathers present. These effects may be mediated by high socioeconomic status and high levels of parental investment among the children of labor migrants, and a combination of low investment, high psychosocial stress, and low alloparental investment among women with divorced/deserted fathers. Our findings are most consistent with the Child Development Theory model of female life history strategies, though the Paternal Investment and Psychosocial Acceleration models also help explain differences between women in low paternal investment situations (e.g., father divorced/abandoned vs. father dead). Father absence in and of itself seems to have little effect on the life history strategies of Bangladeshi women once key reasons for or correlates of absence are controlled, and none of the models is a good predictor of why women with deceased fathers have delayed life histories compared with women whose fathers are present.

Absence of evidence arguments are indispensable to comparative neurobiology. The absence in a given species of a homologous neural architecture strongly correlated with a type of conscious experience in humans should be able to be taken as a prima facie reason for concluding that the species in question does not have the capacity for that conscious experience. Absence of evidence reasoning is, however, widely disparaged for being both logically illicit and unscientific. This paper argues that these concerns (...) are unwarranted. There is no logical barrier to formulating cogent absence of evidence arguments; indeed, accepting such arguments is part of what it is to be committed to falsifiability as a critical aspect of the scientific method. Absence of evidence arguments can always be blocked, however, by assuming that psychological properties are ‘multiply realizable’. While we take multiple realizability to be highly likely at some level of analysis, we argue that it is question-begging to assume that it exists at every level of analysis, and thus it should not automatically be thought to undermine absence of evidence reasoning in the animal consciousness debate. Using the example of pain and focusing on homologies at the level of information processing tasks, we show how, in the science of consciousness, an absence of evidence might well serve as evidence of absence.
