El estudio de la onomástica femenina de los Banū Marīn de Fez ha adolecido, por lo general, de un análisis profundo y monográfico, a pesar de la gran utilidad de dichos nombres para definir mejor distintos rasgos de la idiosincrasia de esta estirpe. El objetivo principal del presente trabajo es cubrir precisamente dicha laguna científica, ofreciendo un análisis tanto filológico como socio-cultural del amplio catálogo de nombres femeninos presentes en el árbol genealógico meriní, desde el rigor científico. Como se intentará (...) demostrar, tales denominaciones constituyen valiosos recursos para reconstruir la diversidad identitaria (étnica, geográfica, prosopográfica, cultural, etc.) no solo de este conjunto de mujeres, sino también de los soberanos con los que se relacionaron en distintas calidades familiares. Igualmente, tales nomenclaturas permiten identificar con una mayor precisión las estrategias de legitimación político-religiosa que esta estirpe diseñó tanto en el plano socio-cultural árabe como en el religioso islámico.

Los teóricos que defienden las técnicas de modificación genética sin algún conservadurismo argumentan que éstas aumentarán nuestras capacidades y, también, evitarán el dolor innecesario junto con algunos tipos de sufrimiento humano. Autores transhumanistas como Nick Bostrom, Natasha Vita-More y Max More, no sólo minusvaloran los riesgos del uso de biotecnología –así como la técnica CRISPR-CAS9–, sino que asumen que vivir una vida humana plena se relaciona en proporción directa con el pleno gozo de nuestras habilidades físicas e intelectuales y con (...) la ausencia de dolor o sufrimiento. No obstante, la visión de algunos teóricos sobre la discapacidad como Fiona Campbell, Elizabeth Barnes y Bárbara Arneil, insisten en que las limitaciones humanas no deberían ser vistas de manera trágica o como una desgracia; al contrario, argumentan que es posible vivir plenamente desde la diversidad funcional (o discapacidad). Por tanto, en este artículo ponemos a prueba ambos supuestos, a partir de la idea de discapacidad y, así, mostraremos si es que la felicidad depende fuertemente de la funcionalidad del cuerpo humano.

Desde 1753, en que fue creado por el insigne marino Jorge Juany Santacilia, el Real Instituto y Observatorio de la Armada (ROA) ha sido el núcleo de la investigación científica de la Armada, manteniendo hoy día un reconocido prestigio tanto a nivel nacional como internacional. El autor de este artículo, director del ROA, a través de una síntesis descriptiva de la estructura orgánica del centro en cuatro Secciones (Efemérides, Astronomía, Geofísica, y Hora), nos introduce en la evolución histórica de esta (...) institución y en la amplia gama de actividades que desarrolla en la actualidad, participando en numerosos proyectos y foros internacionales, y manteniendo relaciones de colaboración permanente con organismos científicos similares de diversos países. Sus publicaciones de efemérides astronómicas, sus trabajos en geomagnetismo, sismología, seguimiento de satélites, astrofísica, metrología, etc. etc., así como el hecho de ser el depositario del Patrón Nacional de la unidad de tiempo, son el exponente de que el ROA continúa siendo un centro científico en plena actividad y pujanza, y en no pocas ocasiones la voz de España en el concierto internacional de estas ramas del conocimiento y de la investigación. Finaliza el artículo con una breve referencia a la Escuela de Estudios Superiores, vinculada al ROA desde su creación y que continúa con sus cursos de «estudios mayores» manteniendo vivo el espíritu científico de la Armada, mediante la formación de un selecto núcleo de oficiales en las áreas de ciencias Físico-Matemáticas, Astronomía y Geofísica, y en la preparación para los cursos de Ingeniería.

Abilities are in many ways central to what being an agent means, and they are appealed to in philosophical accounts of a great many different phenomena. It is often assumed that abilities are some kind of dispositional property, but it is rarely made explicit exactly which dispositional properties are our abilities. Two recent debates provide two different answers to that question: the new dispositionalism in the debate about free will, and virtue reliabilism in epistemology. This paper argues that both answers (...) fail as general accounts of abilities, and discusses the ramifications of this result. (shrink)

It is a familiar point that many ordinary dispositions are multi-track, that is, not fully and adequately characterisable by a single conditional. In this paper, I argue that both the extent and the implications of this point have been severely underestimated. First, I provide new arguments to show that every disposition whose stimulus condition is a determinable quantity must be infinitely multi-track. Secondly, I argue that this result should incline us to move away from the standard assumption that dispositions are (...) in some way importantly linked to conditionals, as presupposed by the debate about various versions of the ‘conditional analysis’ of dispositions. I introduce an alternative conception of dispositionality, which is motivated by linguistic observations about dispositional adjectives and links dispositions to possibility instead of conditionals. I argue that, because of the multi-track nature of dispositions, the possibility-based conception of dispositions is to be preferred. (shrink)

Fundamental to spatial knowledge in all species are the representations underlying object recognition, object search, and navigation through space. But what sets humans apart from other species is our ability to express spatial experience through language. This target article explores the language ofobjectsandplaces, asking what geometric properties are preserved in the representations underlying object nouns and spatial prepositions in English. Evidence from these two aspects of language suggests there are significant differences in the geometric richness with which objects and places (...) are encoded. When an object is named (i.e., with count nouns), detailed geometric properties – principally the object's shape (axes, solid and hollow volumes, surfaces, and parts) – are represented. In contrast, when an object plays the role of either “figure” (located object) or “ground” (reference object) in a locational expression, only very coarse geometric object properties are represented, primarily the main axes. In addition, the spatial functions encoded by spatial prepositions tend to be nonmetric and relatively coarse, for example, “containment,” “contact,” “relative distance,” and “relative direction.” These properties are representative of other languages as well. The striking differences in the way language encodes objects versus places lead us to suggest two explanations: First, there is a tendency for languages to level out geometric detail from both object and place representations. Second, a nonlinguistic disparity between the representations of “what” and “where” underlies how language represents objects and places. The language of objects and places converges with and enriches our understanding of corresponding spatial representations. (shrink)

Metaphysicians of modality are increasingly critical of possible-worlds talk, and increasingly happy to accept irreducibly modal properties – and in particular, irreducible dispositions – in nature. The aim of this paper is to provide the beginnings of a modal semantics which uses, instead of possible-worlds talk, the resources of such an 'anti-Humean' metaphysics. One central challenge to an anti-Humean view is the context-sensitivity of modal language. I show how that challenge can be met and a systematic modal semantics provided, given (...) an independently plausible metaphysics of dispositional properties or potentialities. (shrink)

In this article, I trouble the pedagogical practice of comforting discomfort in the social-justice classroom. Is it possible to support white students, for instance, and not comfort them? Is it possible to support white students without recentering the emotional crisis of white students, without disregarding the needs and interests of students of color, and without reproducing the violence that students of color endure? First I address the dangers of comforting discomfort and discuss Robin DiAngelo's notion of white fragility, which has (...) been used to explain the tendency of white people to flee discomfort rather than tarry with it. Employing Erinn Gilson's work on vulnerability, I argue that white fragility is not a weakness but an active performance of invulnerability. I conclude by arguing that developing vulnerability is a counter to white fragility, and that one way such vulnerability can be encouraged is through offering critical hope, which I maintain is a type of support that does not comfort.

This paper makes a plea for more reflexive attempts to develop and anchor the emerging concept of responsible research and innovation. RRI has recently emerged as a buzzword in science policy, becoming a focus of concerted experimentation in many academic circles. Its performative capacity means that it is able to mobilise resources and spaces despite no common understanding of what it is or should be ‘made of’. In order to support reflection and practice amongst those who are interested in and (...) using the concept, this paper unpacks understandings of RRI across a multi-disciplinary body of peer-reviewed literature. Our analysis focuses on three key dimensions of RRI that remain particularly opaque. A total of 48 publications were selected through a systematic literature search and their content was qualitatively analysed. Across the literature, RRI is portrayed as a concept that embeds numerous features of existing approaches to govern and assess emerging technologies. Our analysis suggests that its greatest potential may be in its ability to unify and provide political momentum to a wide range of long-articulated ethical and policy issues. At the same time, RRI’s dynamism and resulting complexity may represent its greatest challenge. Further clarification on what RRI has to offer in practice—beyond what has been offered to date—is still needed, as well as more explicit engagement with research and institutional cultures of responsibility. Such work may help to realise the high political expectations that are attached to nascent RRI. (shrink)

To reduce sex differences in employment outcomes, we must examine them in the context of the sex-gender hierarchy. The conventional explanation for wage gap—job segregation—is incorrect because it ignores men's incentive to preserve their advantages and their ability to do so by establishing the rules that distribute rewards. The primary method through which all dominant groups maintain their hegemony is by differentiating the subordinate group and defining it as inferior and hence meriting inferior treatment. My argument implies that neither sex-integrating (...) jobs nor implementing comparable worth will markedly improve women's employment status because men can subvert these mechanisms or even change the rules by which rewards are allocated. As evidence, I show that occupational integration has failed to advance women appreciably, and I argue that comparable worth is not likely to be much more effective. Instead, we must seek political analyses and political solutions. (shrink)

Most of us have been brought up on the idea that moral theories divide as they are, at the root, either deontological or consequentialist. A new point of division has been emerging that places deontological and consequentialist theories together against theories of virtue, or a conception of morality constrained at the outset by the requirements of the “personal.” In a series of important essays Bernard Williams has offered striking arguments for the significance of the personal in moral thought based on (...) the role of integrity in human activity and character. His criticisms of both Kantian and utilitarian theories for their deep-seated tendencies to undermine the integrity of persons brings to a new level of seriousness and subtlety long-standing complaints against these theories—the invasive do-gooding of utilitarianism, the coldness and severity toward normal human concerns of Kantian theory. Although Williams is inclined to find the sources of the attack on integrity in these different features of the two traditional theories, in the end his complaint against both of them turns on their demand that the moral agent submit himself to the authority of impartial value.

Charles Taylor argues that recognition begins with the politics of "self-image," as groups represented in the past by others in ways harmful to their own identity replace negative historical self-images with positive ones of their own making. Given the centrality of "self image" to his politics of recognition, it is striking that Taylor, himself, represents disabled people in language that is both limiting and depreciating. The author argues such negative self-images are not unique to Taylor but endemic to modern political (...) thought from John Locke to John Rawls, as the disabled are constituted in direct opposition to the rational person and/or citizen. Using contemporary social theories of disability, as articulated by disabled scholars and advocates, the author concludes that such negative self-images must be purged from political theory and replaced with an alternative theory of personhood/citizenship rooted in the image of interdependency.

The article argues that the relationship to time is at the root of what makes us human and that culture arises with and from efforts to transcend death, change and the rhythmicity of the physical environment. Time can be tracked through systems of time measurement and later transformed from a process of nature into clock time, a time to human design that is abstracted from context and content. In this form time can be traded with all other times. With contemporary (...) science and new information and communications technologies, which operate in a new all-encompassing temporal spectrum that extends from nanoseconds to millennia, clock time is no longer appropriate to the associated present-oriented transactions and futures are traversed in the dual sense of the word. By historically locating temporal relations, the article provides both a new understanding of socio-cultural relations and a perspective on social change. (shrink)

The particular design of any technology may have profound social implications. Computing technologies are deeply intermeshed with the activities of daily life, playing an ever more central role in how we work, learn, communicate, socialize, and participate in government. Despite the many ways they have improved life, they cannot be regarded as unambiguously beneficial or even value-neutral. Recent experience shows they can lead to unintended but harmful consequences. Some technologies are thought to threaten democracy through the spread of propaganda on (...) online social networks, or to threaten privacy through the aggregation of datasets that include increasingly personal information, or to threaten justice when machine learning is used in such high-stakes, decision-making contexts as loan application reviews, employment procedures, or parole hearings. It is insufficient to ethically assess technology after it has produced negative social impacts, as has happened, for example, with facial recognition software that discriminates against people of color and with self-driving cars that are unable to cope with pedestrians who jay-walk. Developers of new technologies should aim to identify potential harmful consequences early in the design process and take steps to eliminate or mitigate them. This task is not easy. Designers will often have to negotiate among competing values—for instance, between efficiency and accessibility for a diverse user population, or between maximizing benefits and avoiding harm. There is no simple recipe for identifying and solving ethical problems. -/- Computer science education can help meet these challenges by making ethical reasoning about computing technologies a central element in the curriculum. Students can learn to think not only about what technology they could create, but also whether they should create that technology. Learning to reason this way requires courses unlike those currently standard in computer science curricula. A range of university courses on topics in areas of computing, ethics, society and public policy are emerging to meet this need. Some cover computer science broadly, while others focus on specific problems like privacy and security; typically, these classes exist as stand-alone courses in the computer science curriculum. Others have integrated ethics into the teaching of introductory courses on programming, artificial intelligence, and human-computer interaction. (shrink)

The prototypes of definiteness and indefiniteness in English are the definite article the and the indefinite article a/an, and singular noun phrases (NPs)1 determined by them. That being the case it is not to be predicted that the concepts, whatever their content, will extend satisfactorily to other determiners or NP types. However it has become standard to extend these notions. Of the two categories definites have received rather more attention, and more than one researcher has characterized the category of definite (...) NPs by enumerating NP types. Westerståhl (1985), who is concerned only with determiners in the paper cited, gives a very short list: demonstrative NPs, possessive NPs, and definite descriptions. Prince (1992) lists proper names and personal pronouns, as well as NPs with the, a demonstrative, or a possessive NP as determiner. She notes, in addition, that “certain quantifiers (e.g. all, every) have been argued to be definite” (Prince 1992: 299). This list, with the quantifiers added, agrees with that given by Birner & Ward (1998, 114). Ariel (1988, 1990) adds null anaphoric NPs. (shrink)

Elementary set theory accustoms the students to mathematical abstraction, includes the standard constructions of relations, functions, and orderings, and leads to a discussion of the various orders of infinity. The material on logic covers not only the standard statement logic and first-order predicate logic but includes an introduction to formal systems, axiomatization, and model theory. The section on algebra is presented with an emphasis on lattices as well as Boolean and Heyting algebras. Background for recent research in natural language semantics (...) includes sections on lambda-abstraction and generalized quantifiers. Chapters on automata theory and formal languages contain a discussion of languages between context-free and context-sensitive and form the background for much current work in syntactic theory and computational linguistics. The many exercises not only reinforce basic skills but offer an entry to linguistic applications of mathematical concepts. For upper-level undergraduate students and graduate students in theoretical linguistics, computer-science students with interests in computational linguistics, logic programming and artificial intelligence, mathematicians and logicians with interests in linguistics and the semantics of natural language.

The problem of collecting, analyzing and evaluating evidence on adverse drug reactions (ADRs) is an example of the more general class of epistemological problems related to scientific inference and prediction, as well as a central problem of the health-care practice. Philosophical discussions have critically analysed the methodological pitfalls and epistemological implications of evidence assessment in medicine, however they have mainly focused on evidence of treatment efficacy. Most of this work is devoted to statistical methods of causal inference with a special (...) attention to the privileged role assigned to randomized controlled trials in Evidence Based Medicine. Regardless of whether the RCT’s privilege holds for efficacy assessment, it is nevertheless important to make a distinction between causal inference of intended and unintended effects, in that the unknowns at stake are heterogonous in the two contexts. This point has been emphasized by epidemiologists in the last decade. Their main focus is methodological, and regards the fact that bias and confounding do not affect studies on intended and unintended effects in the same way. However, deeper concerns ground the intuition for such a distinction; these are related to the constraints which we impose on evidence and their epistemological justification. My thesis is that such constraints ought to be understood to be different in the case of evidence for risk vs. benefit assessment. I present the recent debate on the causal association between acetaminophen and asthma in order to illustrate the point at issue. (shrink)

: The main threads of Emmanuel Levinas's theory of ethics, developed in his philosophical works, Totality and Infinity (1969), and Otherwise than Being or Beyond Essence (1998), instruct that ethics require transcendence of being and nature, which he describes in terms of a transcendence of animality to the human. This apparent devaluation of the nonhuman would seem to preclude the development of Levinasian environmental ethics. However, a deconstructive reading of Levinas recognizes a subtext that interrupts the main threads of his (...) argument running against the inclusion of nonhuman others in ethics. Through a critical reconstructive reading of Levinas, I develop an ethic extraneous to Levinas's transcendent ethics, an ethic outside his "otherwise than being.". (shrink)

This paper began in the startled realization that little if anything is said in Kant’s ethics about the more violent forms of immoral action. There are discussions of lying, deception, self-neglect, nonbeneficence—but apart from suicide, a great silence about the darker actions. At the least, this should be an occasion for curiosity. Although the degree of concern with acts of violence in contemporary ethics may be in its own way curious, it does not seem unreasonable to expect a moral theory (...) to provide an account of what is wrong with acts of violence.

The theme of this special issue is Post-truth. No doubt it was my exasperation with the terminological state of our collective situation that incited me in the spring of 2017 to settle upon it.

This paper aims to determine whether extended human-machine cognitive systems and group systems can be regarded as autonomous agents. For this purpose, I compare two notions of agency: one developed within analytical philosophy of action and based on the concept of intention, and the other introduced by enactivists via the concepts of autopoiesis and sensorimotor autonomy. I argue that only the latter approach can be used to demonstrate autonomous agency in respect of systems that are not humans as such, though (...) they contain humans as their elements. After introducing Maturana and Varela’s conception of minimal autonomy as a kind of generalization of autopoiesis, I present the three conditions of agency put forward by Barandiaran, Di Paolo and Rohde, noting that they do not invoke the property of being alive as necessary in that respect. I argue that both extended and group systems can satisfy these conditions of agency, even though they are not alive as such. The fulfillment of these conditions, however, is ensured by the autopoietic nature of the living components of these systems. That being said, an autonomous system itself does not need to be alive in the biological sense. Sensorimotor, adaptive agency could emerge out of other processes than those responsible for biological life. The article concludes with a suggestion that this is exactly what will happen if an autonomous system is ever artificially created. It would be functionally indistinguishable from a living organism, though not alive in a biological sense. (shrink)

This paper provides a philosophical analysis and a new edition of an anonymous Epitome of John Dumbleton’s solution to the semantic paradoxes.

The phrase "natural kind term" has come into the linguistic and philosophical literature in connection with well-known work of Kripke (1972) and Putnam (1970, 1975a). I use that phrase here in the sense it has acquired from those and subseqnent works on related topics. This is not the transparent sense of the phrase. That is, if I am right in what follows there are words for kinds of things existing in nature which are not natural kind terms in the current (...) sense - e.g. planet, woman, and weed. I use the term "nondescriptional", following Salmon (1981), to mean "lacking a Fregean sense", where a Fregean sense is taken to be a property or group of properties semantically associated with an expression which determines its denotation. I hope that the term "nondescriptional" will be clarified in subsequent discussion, but perhaps a few words about it and its opposite, "descriptional", would be useful here. These terms (as Salmon notes (p.15, n. 11)) should be taken as technical terms. The idea is that descriptional words, of which bachelor is the overwhelmingly favorite example, express a semantic content, or sense, which is what mediates their denotation. Entities fall in their denotation in virtue of possessing the property or properties expressed as their sense. (It is not necessary, however, that this sense be as easily paraphrasable with descriptive synonyms as it is typically held to be in the case of bachelor, or even that it be paraphrasable at all.) In the case of nondescriptional words there is no Fregean sense to mediate the link between word and object. Hence such terms are described by what Salmon, following Kaplan, calls "the theory of direct reference". What it is that does associate such terms with their denotations is another question which will be touched on briefly at the end. I have several aims in this paper. The first is to defend a conservative position on nondescriptionality. I will argue that relatively few natural language words have this property. My other aims are primarily clarificatory. Among the issues I would like to clarify are those connected with the determination of this property and flae explanation of why it exists, its relationship with other properties such as rigid designation and essentiality, and its significance for lexical semantics. The organization of the paper is as follows. The first section identifies the position taken here on the question of which expressions are nondescriptional and provides a general defense of it. The second section is a critical examination of criteria associated with nondescriptionality. In the third section provide further defense for the conservative position, and in the fourth section we turn to related issues in lexical semantics. (shrink)

In a highly original rereading of the writings and seminars of Jacques Lacan, together with works of Freud and others, Cassin shows how psychoanalysis, like the sophists, challenges the very foundations of scientific rationality. In taking seriously equivocations, jokes, and unfinishable projects of interpretation, the analyst, like the sophist, allows performance, signifier, and inconsistency to reshape truth.

Canadian nursing practice has been profoundly influenced by the legalization of medical assistance in dying in 2016, requiring that nurses navigate new and sometimes highly challenging experiences. Findings from our longitudinal studies of nurses' experiences suggest that these include deep emotional responses to medical assistance in dying, an urgency in orchestrating the perfect death, and a high degree of relational impact, both professionally and personally. Here we propose a theoretical explanation for these experiences based upon a relational ontology. Drawing upon (...) the work of Wildman, we understand a relational ontology to be one in which relationships are more fundamentally central than the conceptual entities that provide the context to practice. It is in a relationship that conceptual entities, and their affiliated values, are created and recreated. Seen as causal, relationships have ontological status, with important implications for how we consider the concepts of death, suffering, and time in this context. From a conceptual perspective, suffering is primarily self‐defined based upon personal histories, time reflects the potential remaining until death, and death is primarily biological and amoral, although social discourses of a good and bad death surround the death trajectory. However, within a relational ontology of medical assistance in dying, these understandings shift. Death becomes primarily social rather than biological, suffering is shared, and time until death is now clearly delimited. Accordingly, nurses assume a profound responsibility for influencing outcomes that are authentically person‐centered. These understandings provide important insights into nurses' experiences, enabling us to recognize the causal effects, both intended and unintended, of nurses' relational practices amidst the complexities of assisted death. Drawing on such a perspective, we find implications for how we provide spaces for nurses to reflect on, and have conversations about, their experiences with some of the greatest mysteries of life—death, suffering, and time.

Culturally different connotations of basic concepts challenge the comparative study of religion. Do persons in Germany or in the United States refer to the same concepts when talking about ‘spirituality’ and ‘religion’? Does it make a difference how they identify themselves? The Bielefeld-Chattanooga Cross-Cultural Study on ‘Spirituality’ includes a semantic differential approach for the comparison of self-identified “neither religious nor spiritual”, “religious”, and “spiritual” persons regarding semantic attributes attached to the concepts ‘religion’ and ‘spirituality’ in each research context. Results show (...) that ‘spirituality’ is used as a broader concept than ‘religion’. Regarding religion, semantics attributed by self-identified religious persons differ significantly from those of the spiritual persons. The ‘spiritual’ and the ‘religious’ groups agree on semantics attributed to spirituality but differ from the ‘neither spiritual nor religious’ group. Qualifications of differences and agreements become visible from the comparison between the United States and Germany. It is argued for the semantically sensitive study of culturally situated ‘spiritualities’. (shrink)

Our earliest tools are our bodies. Our hands raise and turn and toss and carry and push and pull, our legs walk and climb and kick allowing us to move and act in the world and to create the multitude of artifacts that improve our lives. The list of actions made by our hands and feet and other parts of our bodies is long. What is more remarkable is we turn those actions in the world into actions on thought through (...) gestures, language, and graphics, thereby creating cognitive tools that expand the mind. The focus here is gesture; gestures transform actions on perceptible objects to actions on imagined thoughts, carrying meaning with them rapidly, precisely, and directly. We review evidence showing that gestures enhance our own thinking and change the thought of others. We illustrate the power of gestures in studies showing that gestures uniquely change conceptions of time, from sequential to simultaneous, from sequential to cyclical, and from a perspective embedded in a timeline to an external perspective looking on a timeline, and by so doing obviate the ambiguities of an embedded perspective. We draw parallels between representations in gesture and in graphics; both use marks or actions arrayed in space to communicate more immediately than symbolic language. (shrink)

Mary knows all there is to know about physics, chemistry and neurophysiology, yet has never experienced colour. Most philosophers think that if Mary learns something genuinely new upon seeing colour for the first time, then physicalism is false. I argue, however, that physicalism is consistent with Mary's acquisition of new information. Indeed, even if she has perfect powers of deduction, and higher-level physical facts are a priori deducible from lower-level ones, Mary may still lack concepts which are required in order (...) to deduce from the lower-level physical facts what it is like to see red.
