Recommender systems are artificial intelligence technologies, deployed by online platforms, that model our individual preferences and direct our attention to content we’re likely to engage with. As the digital world has become increasingly saturated with information, we’ve become ever more reliant on these tools to efficiently allocate our attention. And our reliance on algorithmic recommendation may, in turn, reshape us as moral agents. While recommender systems could in principle enhance our moral agency by enabling us to cut through the information (...) saturation of the internet and focus on things that matter, as they’re currently designed and implemented they’re apt to interfere with our ability to attend appropriately to morally relevant factors. In order to analyze the distinctive moral problems algorithmic recommendation poses, we develop a framework for the ethics of attention and an account of judicious attention allocation as a moral skill. We then discuss empirical evidence suggesting that attentional moral skill can be thwarted and undermined in various ways by algorithmic recommendation and related affordances of online platforms, as well as economic and technical considerations that support this concern. Finally, we consider how emerging technologies might overcome the problems we identify. (shrink)

In the Aristotelian tradition, the psychological difference between virtue and continence is commonly understood in terms of inner harmony versus inner conflict. Virtuous agents experience inner harmony between feeling and action because they do not care to do other than what their circumstances call for, whereas continent agents feel conflicted about doing what is called for because of competing concerns. Critics of this view argue, however, that when the circumstances require sacrificing something of genuine value, virtuous agents can indeed feel (...) conflicted about acting well. But if this is so, what differentiates virtuous from merely continent agency? This essay argues that the traditional distinction conflates two aspects of virtue as well as two species of continence. And distinguishing between them provides resources for making sense of the complex relationship between inner conflict and good moral agency. (shrink)

Self-referential sentences have troubled our understanding of language for centuries. The most famous self-referential sentence is probably the Liar, a sentence that says of itself that it is false. The Liar Paradox has encouraged many philosophers to establish theories of truth that manage to give a proper account of the truth predicate in a formal language. Kripke’s Fixed Point Theory from 1975 is one famous example of such a formal theory of truth that aims at giving a plausible notion of (...) truth by allowing truth value gaps. However, not only the concept of truth gives rise to paradoxes. A syntactical treatment of epistemic notions like belief and knowledge leads to contradictions that very much resemble the Liar Paradox. Therefore, it seems to be fruitful to apply the established theories of truth to epistemic concepts. In this paper, I will present one such attempt of solving the epistemic paradoxes: I adapt Kripke’s Fixed Point Theory and interpret truth, knowledge and belief within the framework of a partial logic. Thereby I find not only the fixed point of truth but also the fixed points of knowledge and belief. In this fixed point, the predicates of truth, belief and knowledge find their definite interpretation and the paradoxes are avoided. (shrink)

Justified belief is a core concept in epistemology and there has been an increasing interest in its logic over the last years. While many logical investigations consider justified belief as an operator, in this paper, we propose a logic for justified belief in which the relevant notion is treated as a predicate instead. Although this gives rise to the possibility of liar-like paradoxes, a predicate treatment allows for a rich and highly expressive framework, which lives up to the universal ambitions (...) of investigating epistemological concepts. We start with a base theory for justified belief, and then systematically present putative additional axioms for justified belief. We provide an overview of consistency results when the additional principles are added to the base theory, and discuss their philosophical plausibility. (shrink)

LET ME BEGIN this inquiry with the simple but fundamental fact that the flow of time, or passage, as it is also known, is given in experience, that it is as indubitable an aspect of our perception of the world as the sights and sounds that come in upon us, even though it is not the peculiar property of a special sense. Consider, by way of illustration, that I am now sitting at the desk in my study. This particular event (...) was not present at any earlier time, nor will it be present shortly as I become involved in other activities. The present, as I experience it, is regularly associated with later and later events. It does not hop about capriciously from here to a later time, to a previous time, and then to a much later time, or trace out some other such indiscriminate pattern; instead I find it always in association with the next moment, and as I look backward and inward, so to speak, I find that the prior moment was present and that this next-later moment is present. Quite often this condition is expressed by means of imagery. We are asked to envision either a moving present racing along a fixed track of moments or events from earlier to later, or alternatively a fixed present through which stream a series of moments or events, first the earlier and then the later ones. One is in truth hard-pressed to find references to passage which do not employ quasi-poetical tropes and metaphors, and while these do help in some sense to say what we mean, great caution is required when handling them because of their ready tendency to draw us away from the actual phenomenon requiring explanation.

Werner Schuster was a doctor long before he became an artist--but it was a childhood fascination with photography that drove him to study radiology in the first place, so it's only fitting that he should now be one of the most versatile and interesting artists working with x-ray photography today. This volume presents full-color reproductions of Schuster's photographs along with those of other photographers, from the pioneering x-ray creators of 1895 to present-day artists working in the medium. An (...) essay by René Harather tells the history of x-ray photography and highlights the most important developments and proponents of the genre since its discovery. The second part of the book turns to Schuster's work, showing how he has expanded the boundaries of the medium and made creative use of the interplay between traditional and x-ray photography. A fascinating look at a stunning marriage of art and science, X-Ray is the first comprehensive representation of the history of x-ray photography. (shrink)

According to agent-centered virtue ethics, acting well is not a matter of conforming to agent-independent moral standards, like acting so as to respect humanity or maximize utility. Instead, virtuous agents determine what is called for in their circumstances through good practical reason. This is an attractive view, but it requires a plausible account of how good practical reason works. To that end, some theorists invoke the skill model of virtue, according to which virtue involves essentially the same kind of practical (...) reason as ordinary skills. I contend, however, that ordinary skills provide a plausible and informative model of good practical reason only insofar as they are assessed by agent-independent standards. And so virtue, likewise, must be assessed primarily by agent-independent moral standards, if the skill model is to serve its purpose. I consider how agent-centered virtue ethics might avert this dilemma. But I ultimately suggest proceeding a different way. (shrink)

Die Studien und Texte zur Sozialgeschichte der Literatur (STSL) veröffentlichen seit 1975 herausragende literatur-, geschichts- und kulturwissenschaftliche Arbeiten zu vornehmlich deutscher Literatur vom Mittelalter bis zur Gegenwart. Schwerpunkt der literaturgeschichtlichen und theoretischen Abhandlungen sowie der Quellen- und Materialienbände ist das Verhältnis von literarischem Text und gesellschaftlich-historischem Kontext. Als maßgebliche Publikationsreihe einer seit den 1960er Jahren einflussreichen Sozialgeschichte der Literatur prägt STSL zugleich die literaturwissenschaftliche Diskussion über mögliche Austauschbeziehungen zwischen Literatur-, Geschichts- und Sozialwissenschaften.

One main goal of argumentation theory is to evaluate arguments and to determine whether they should be accepted or rejected. When there is no clear answer, a third option, being undecided, has to be taken into account. Indecision is often not considered explicitly, but rather taken to be a collection of all unclear or troubling cases. However, current philosophy makes a strong point for taking indecision itself to be a proper object of consideration. This paper aims at revealing parallels between (...) the findings concerning indecision in philosophy and the treatment of indecision in argumentation theory. By investigating what philosophical forms and norms of indecision are involved in argumentation theory, we can improve our understanding of the different uncertain evidential situations in argumentation theory.

When there are two lines of argument that contradict each other but still end up with the same conclusion, this conclusion is called a floating conclusion. It is an open topic in skeptical defeasible reasoning if floating conclusions ought to be accepted. Inter- estingly, the answer seems to be changing for different examples. In this paper, we propose a solution for explaining the different treatments of the floating conclusion in the various examples from the literature. We collect the examples from (...) the literature, extend them with additional examples and test various hypotheses for explaining the difference by means of the examples. We will argue for a framework that accepts a floating conclusion by default but allows for reasons to deviate from the default in order to reject it. These reasons nicely explain the different underlying patterns of our intuitions. (shrink)

ABSTRACT A new phenomenon in the philosophical discipline, philosophical practice—or counselling—is introduced to the reader through the description of three different approaches to philosophical practice. What is common to these approaches is that an academically trained philosopher philosophises together with a ‘sane’person—the visitor—on questions and problems relevant to the visitor. The essential difference between this and psychological counselling is that philosophers do not use therapeutic methods or make diagnoses. The philosophical practitioner triggers in his dialogue partner a didactic philosophical process, (...) which enables the visitor to become an authentic thinker and eventually to arrive at philosophical answers by her/himself. The effectiveness of the language used in philosophical practice is not so much in applying philosophical ideas or theories as in the philosophical knowledge, skills and attitudes attained by the visitor.

John Stuart Mill, whose relevance for Nietzsche’s late work has been documented by recent research, is not directly mentioned in On the Genealogy or Morality (1887). This article argues that Mill’s On Liberty (1859) nevertheless played a crucial role in the development of the Genealogy. Following a source-based methodology, three major references demonstrate how Nietzsche used On Liberty as a resource as he initiated and developed his own exploration into the origin of morality. After tracing Nietzsche’s reading of Mill through (...) pencil marks in his copy of On Liberty, I discuss the reappearance of Mill’s motives and terminology as well as the explanatory power of Mill as a source for the respective sections in the Genealogy. It becomes clear to what extent Nietzsche adapts Mill and how he turns Mill’s own weapons against him through skillful transformations. The article concludes that instead of delivering the “better” Mill, Nietzsche builds up a fruitful tension between a then-common take on morality and its transgression. (shrink)

This book reconstructs key aspects of the early career of Descartes from 1618 to 1633; that is, up through the point of his composing his first system of natural philosophy, Le Monde, in 1629-33. It focuses upon the overlapping and intertwined development of Descartes’ projects in physico-mathematics, analytical mathematics, universal method, and, finally, systematic corpuscular-mechanical natural philosophy. The concern is not simply with the conceptual and technical aspects of these projects; but, with Descartes’ agendas within them and his construction and (...) presentation of his intellectual identity in relation to them. Descartes’ technical projects, agendas and senses of identity shifted over time, entangled and displayed great successes and deep failures, as he morphed from a mathematically competent, Jesuit trained graduate in neo-Scholastic Aristotelianism to aspiring prophet of a systematised corpuscular-mechanism, passing through stages of being a committed physico-mathematicus, advocate of a putative ‘universal mathematics’, and projector of a grand methodological dream. In all three dimensions—projects, agendas and identity concerns—the young Descartes struggled and contended, with himself and with real or virtual peers and competitors, hence the title ‘Descartes-Agonistes’.

El artículo tiene como objetivo realizar un análisis del mercado de la pornografía y su impacto en la desigualdad y subordinación de las mujeres. Partiendo del estudio teórico de Debra Satz respecto a la prostitución (2010), sostendremos que la pornografía es un mercado nocivo. A partir de esta afirmación, estudiaremos la diferencia entre este mercado y otros que tienen efectos similares. Luego consideraremos los costos y beneficios en términos de derechos, así como las posibilidades fácticas y la eficiencia de medidas (...) prohibitivas para su regulación. Concluiremos que, por más que la pornografía sea un mercado moralmente objetable, su prohibición estatal no es una derivación obvia de esta afirmación. (shrink)

The aim of this exploratory study was to examine client demographics and expectations, reasons for use, sensations during treatment, and perceived outcomes of Pranic Healing, an energy healing system lacking in scientific documentation but whose use in the general population is becoming more widespread internationally. This study consisted of a cross-sectional survey of adults (18+ years of age) receiving care from 12 Pranic Healing practices in four different states in the U.S. (N = 179) completing online questionnaires. Closed-ended response sets (...) were analyzed descriptively, while qualitative data were analyzed using content analysis. Reasons to use the therapy included physical, mental/emotional, and metaphysical issues, dissatisfaction with conventional care, and overall well-being. Expectations of care included enhanced abilities, cure or relief, or unsure. Respondents were more likely to cite a specific problem from which they needed alleviation than to cite overall health or wellness as their goal. Sensations experienced were reported to be of a relaxing nature and not, as was hypothesized, of an energizing nature. Results show that those who use Pranic Healing fit the sociodemographic profile of CAM (complementary and alternative medicine) users in the United States, that their reasons for use are not homogeneous, and that preliminary descriptive data from a selective subsample of respondents indicated that some respondents are experiencing positive outcomes attributed to this modality.

The Dedekind cuts in an ordered set form a set in the sense of constructive Zermelo—Fraenkel set theory. We deduce this statement from the principle of refinement, which we distill before from the axiom of fullness. Together with exponentiation, refinement is equivalent to fullness. None of the defining properties of an ordering is needed, and only refinement for two—element coverings is used. In particular, the Dedekind reals form a set; whence we have also refined an earlier result by Aczel and (...) Rathjen, who invoked the full form of fullness. To further generalise this, we look at Richman's method to complete an arbitrary metric space without sequences, which he designed to avoid countable choice. The completion of a separable metric space turns out to be a set even if the original space is a proper class; in particular, every complete separable metric space automatically is a set. (shrink)

En nuestro trabajo analizamos la propuesta de una norma del gusto por parte de David Hume en el marco de su filosofía escéptica. Nuestra investigación parte de la premisa de que el filósofo no logra consolidar los principios básicos de una Ciencia del Hombre tal como él mismo propone en la Introducción del Tratado de la naturaleza humana y que, por lo tanto, en varios ámbitos del saber no es posible distinguir cuáles son los principios últimos que rigen el entendimiento (...) y la conducta de los seres humanos. La experiencia estética no escapa a esta dificultad. En este sentido, en nuestro estudio indagamos cuál es el objetivo y la finalidad de Hume en los Ensayos morales políticos y literarios al proponer el dictamen de jueces idóneos como guía de las valoraciones estéticas. Nuestra atención está puesta en determinar por qué un pensador escéptico estaría interesado en regular los juicios de gusto. Al mismo tiempo, y a fin de desentrañar en toda su complejidad la propuesta humeana, nos detendremos a examinar los rasgos característicos de la esfera de la sensibilidad teniendo en cuenta sus semejanzas y diferencias con el pensamiento de Hutcheson.

In this analysis of Yalom’s account of philosophical counseling I show that his perception of it is largely informed by his own ideas about existential psychotherapy and group therapy. Additionally I find that When Nietzsche Wept, and The Schopenhauer Cure comply with Yalom’s personal development and struggles in psychotherapy with philosophy, religion, and boundary violations. Conflicting ideas and attitudes concerning the formerly mentioned are traced also in other works by Yalom.

Examples are cited of group hunting in chimpanzees, lions, and hyenas consistent with evidence for intentionality, organization, and coordination. These challenge the claim for shared intentionality as uniquely human. Even when rarely performed in this way, the significance of such behaviors should not be minimized, especially if this level of “intelligent” action emerges spontaneously in the wild.

The topic of this article is the formal topology abstracted from the Zariski spectrum of a commutative ring. After recollecting the fundamental concepts of a basic open and a covering relation, we study some candidates for positivity. In particular, we present a coinductively generated positivity relation. We further show that, constructively, the formal Zariski topology cannot have enough points.
