When young children attempt to locate numbers along a number line, they show logarithmic (or other compressive) placement. For example, the distance between “5” and “10” is larger than the distance between “75” and “80.” This has often been explained by assuming that children have a logarithmically scaled mental representation of number (e.g., Berteletti, Lucangeli, Piazza, Dehaene, & Zorzi, 2010; Siegler & Opfer, 2003). However, several investigators have questioned this argument (e.g., Barth & Paladino, 2011; Cantlon, Cordes, Libertus, & (...) Brannon, 2009; Cohen & Blanc-Goldhammer, 2011). We show here that children prefer linear number lines over logarithmic lines when they do not have to deal with the meanings of individual numerals (i.e., number symbols, such as “5” or “80”). In Experiments 1 and 2, when 5- and 6- year-olds choose between number lines in a forced-choice task, they prefer linear to logarithmic and exponential displays. However, this preference does not persist when Experiment 3 presents the same lines without reference to numbers, and children simply choose which line they like best. In Experiments 4 and 5, children position beads on a number line to indicate how the integers 1 100 are arranged. The bead placement of 4- and 5-year-olds is better fit by a linear than by a logarithmic model. We argue that previous results from the number line task may depend on strategies specific to the task.

The role to be played by multi-stakeholder partnerships in addressing the ‘wicked problems’ of sustainable development is made explicit by the seventeenth Sustainable Development Goal. But how do these partnerships really work? Based on the analysis of four sustainability-oriented innovation initiatives implemented in Belgium, Italy, Germany, and France, this study explores the roles and mechanisms that collaborating actors may enact to facilitate the pursuit of sustainable development, with a particular focus on non-profit organizations. The results suggest that collaborative innovations for (...) sustainability contribute simultaneously to the fulfilment of different Sustainable Development Goals, reaching beyond their original intent, and that the value being created has the potential to reinforce such roles and mechanisms. These partnerships are prompted and managed by non-profit organizations that act as metagovernors of collaborative innovation processes as they play the roles of cultural spreaders, enablers, relational brokers, service provides, and influencers. These findings will help policy-makers and practitioners in the public and non-profit sector to identify and utilize emerging opportunities for value creation through collaborative innovation, and to better design existing and prospective collaborative efforts aimed at sustainable objectives, thereby supporting progress towards the implementation of Agenda 2030.

Is it possible to establish a line of research that brings Gabriel Marcel and Jean-Paul Sartre closer together? With this article, we will positively support this idea, by distancing ourselves from the overly rigid interpretations that exclusively focus on antinomic elements sliding into a reductionist and nowadays “canonical” presentation of the relationship between these philosophers. Beyond the undeniable and, fortunately, unmediated differences between the two philosophers, this article aims to investigate their positions regarding the concept of “relationship”. In doing so, (...) we will highlight how Gabriel Marcel’s “coesse” and Jean-Paul Sartre’s “being-for-others” have numerous points of contact that place both philosophers, beyond their personal positions in the religious sphere, within the common ground of “existentialism”.

Reference is a central topic in philosophy of language, and has been the main focus of discussion about how language relates to the world. R. M. Sainsbury sets out a new approach to the concept, which promises to bring to an end some long-standing debates in semantic theory.There is a single category of referring expressions, all of which deserve essentially the same kind of semantic treatment. Included in this category are both singular and plural referring expressions, complex and non-complex referring (...) expressions, and empty and non-empty referring expressions. Referring expressions are to be described semantically by a reference condition, rather than by being associated with a referent. In arguing for these theses, Sainsbury's book promises to end the fruitless oscillation between Millian and descriptivist views. Millian views insist that every name has a referent, and find it hard to give a good account of names which appear not to have referents, or at least are not known to do so, like ones introduced through error, ones where it is disputed whether they have a bearer and ones used in fiction. Descriptivist theories require that each name be associated with some body of information. These theories fly in the face of the fact names are useful precisely because there is often no overlap of information among speakers and hearers. The alternative position for which the book argues is firmly non-descriptivist, though it also does not require a referent. A much broader view can be taken of which expressions are referring expressions: not just names and pronouns used demonstratively, but also some complex expressions and some anaphoric uses of pronouns.Sainsbury's approach brings reference into line with truth: no one would think that a semantic theory should associate a sentence with a truth value, but it is commonly held that a semantic theory should associate a sentence with a truth condition, a condition which an arbitrary state of the world would have to satisfy in order to make the sentence true. The right analogy is that a semantic theory should associate a referring expression with a reference condition, a condition which an arbitrary object would have to satisfy in order to be the expression's referent.Lucid and accessible, and written with a minimum of technicality, Sainsbury's book also includes a useful historical survey. It will be of interest to those working in logic, mind, and metaphysics as well as essential reading for philosophers of language. (shrink)

Feasting on a plethora of social media platforms, news aggregators, and online marketplaces, recommender systems (RSs) are spreading pervasively throughout our daily online activities. Over the years, a host of ethical issues have been associated with the diffusion of RSs and the tracking and monitoring of users’ data. Here, we focus on the impact RSs may have on personal autonomy as the most elusive among the often-cited sources of grievance and public outcry. On the grounds of a philosophically nuanced notion (...) of autonomy, we illustrate three specific reasons why RSs may limit or compromise it: the threat of manipulation and deception associated with RSs; the RSs’ power to reshape users’ personal identity; the impact of RSs on knowledge and critical thinking. In our view, however, notwithstanding these legitimate concerns, RSs may effectively help users to navigate an otherwise overwhelming landscape. Our perspective, therefore, is not to be intended as a bulwark to protect the _status quo_ but as an invitation to carefully weigh these aspects in the design of ethically oriented RSs. (shrink)

Obiettivo di questo articolo sarà presentare l’analisi fenomenologica e teoretica che Sartre propone del concetto di malafede, a partire dal romanzo La Nausea fino all’opera L’essere e il nulla. Ricostruendo il procedimento sartriano, che dall’atteggiamento interrogativo dell’uomo di fronte all’essere porta alla posizione del non-essere, giungeremo alla libertà e all’angoscia, quali caratteri costitutivi dell’essenza umana. Il tentativo di fuggire dalla libertà, a cui per Sartre siamo condannati, e dall’angoscia che da essa deriva, condurrà l’uomo sartriano all’autoinganno, ad una vita inautentica… (...) alla malafede.

This book presents state of the art philosophical work on conspiracy theory research that brings in sharp focus on central and important insights concerning the supposed irrationality of conspiracy theory and conspiracy theory belief, while also proposing several novel solutions to long standing issues in the broader academic debate on these things called ‘conspiracy theories’. -/- It features a critical history of conspiracy theory theory, emphasising the role of the ‘first generation’ of philosophers in conspiracy theory research. This book also (...) includes discussions of a range of key issues such as: -/- What counts as conspiracy theory? Who counts as a conspiracy theorist? How are these terms variously understood by academics and the wider public, and Are conspiracy theories automatically suspect, and is it ever reasonable to be a conspiracy theorist? The book then builds upon that work by looking at how people’s political views affect both the conspiracy theories they believe and their beliefs about conspiracy theories; how we might defend conspiracy theorising without endorsing mad, bad or dangerous conspiracy theories; and contains several proposals for unifying conspiracy theory research under one theoretical framework: particularism. -/- This volume will be a key resource for philosophers and social scientists interested in recent work on the philosophy of conspiracy theory theory and its implications for conspiracy theory research. It will also appeal to members of the public, who want to know what, if anything, is wrong with these things called “conspiracy theories”. It was originally published as a special issue of Social Epistemology. (shrink)

Donation after circulatory determination of death (DCDD) is an accepted practice in the United States, but heart procurement under these circumstances has been debated. Although the practice is experiencing a resurgence due to the recently completed trials using ex vivo perfusion systems, interest in thoracoabdominal normothermic regional perfusion (TA-NRP), wherein the organs are reanimated in situ prior to procurement, has raised many ethical questions. We outline practical, ethical, and equity considerations to ensure transplant programs make well-informed decisions about TA-NRP. We (...) present a multidisciplinary analysis of the relevant ethical issues arising from DCDD-NRP heart procurement, including application of the Dead Donor Rule and the Uniform Definition of Death Act, and provide recommendations to facilitate ethical analysis and input from all interested parties. We also recommend informed consent, as distinct from typical “authorization,” for cadaveric organ donation using TA-NRP. (shrink)

This book analyzes for the first time in English the ethical theory that underpins Qur’anic legislation by providing a classification of specific verses in which Islam’s holy book discusses moral issues. The principal purpose of this book is to demonstrate the ways in which the Qur’an theoretically and practically provides the moral code to which Muslims around the world adhere. The author divides his analysis into a survey of Qur’anic attitudes towards the basic ethical issues of obligation and responsibility, issues (...) of moral psychology such as motivation and intention, as well as matters of social ethics such as the function of law in society. He then explores the meanings of individual morality, morality within the family and civil society, and the relationship of morality to the idea of the state. (shrink)

Richard M Weaver, a thinker and writer celebrated for his unsparing diagnoses and realistic remedies for the ills of our age, is known largely through a few of his works that remain in print. This new collection of Weaver's shorter writings, assembled by Ted J Smith III, Weaver's leading biographer, presents many long-out-of-print and never-before-published works that give new range and depth to Weaver's sweeping thought. Included are eleven previously unpublished essays and speeches that were left in near-final form at (...) the time of Weaver's death in 1963. In all, there are some one hundred and twenty-six essays, speeches, book reviews, and editorials. (shrink)

Hegel's Philosophy of Right concerns ideas on justice, moral responsibility, family life, economic activity, and the political structure of the state. It shows how human freedom involves living with others in accordance with publicly recognized righs and laws. This edition combines a revised translation with a cogent introduction to Hegel's work.

On September 1, 2023, Texas made important revisions to it its decades‐old statute granting legal safe harbor immunity to physicians who withhold or withdraw life‐sustaining treatment over the objection of critically ill patients’ surrogate decision‐makers. However, lawmakers left untouched glaring flaws in a key safeguard for patients—the transfer option. The transfer option is ethically important because, when no hospital is willing to accept the patient in transfer, that fact is taken as strong evidence that the surrogates’ treatment requests fall outside (...) accepted medical practice. But there are serious shortcomings in how the transfer option is carried out in Texas and many other states, which undermines the ethical usefulness of the process. We identify these shortcomings and recommend revisions to state statutes and professional guidelines to overcome them. (shrink)

Geometrical intuitions spontaneously drive visuo-spatial reasoning in human adults, children and animals. Is their emergence intrinsically linked to visual experience, or does it reflect a core property of cognition shared across sensory modalities? To address this question, we tested the sensitivity of blind-from-birth adults to geometrical-invariants using a haptic deviant-figure detection task. Blind participants spontaneously used many geometric concepts such as parallelism, right angles and geometrical shapes to detect intruders in haptic displays, but experienced difficulties with symmetry and complex spatial (...) transformations. Across items, their performance was highly correlated with that of sighted adults performing the same task in touch (blindfolded) and in vision, as well as with the performances of uneducated preschoolers and Amazonian adults. Our results support the existence of an amodal core-system of geometry that arises independently of visual experience. However, performance at selecting geometric intruders was generally higher in the visual compared to the haptic modality, suggesting that sensory-specific spatial experience may play a role in refining the properties of this core-system of geometry.

"My work has had nothing to do with gay liberation," Michel Foucault reportedly told an admirer in 1975. And indeed there is scarcely more than a passing mention of homosexuality in Foucault's scholarly writings. So why has Foucault, who died of AIDS in 1984, become a powerful source of both personal and political inspiration to an entire generation of gay activists? And why have his political philosophy and his personal life recently come under such withering, normalizing scrutiny by commentators as (...) diverse as Camille Paglia, Richard Mohr, Bruce Bawer, Roger Kimball, and biographer James Miller? David M. Halperin's Saint Foucault is an uncompromising and impassioned defense of the late French philosopher and historian as a galvanizing thinker whose career as a theorist and activist will continue to serve as a model for other gay intellectuals, activists, and scholars. A close reading of both Foucault and the increasing attacks on his life and work, it explains why straight liberals so often find in Foucault only counsels of despair on the subject of politics, whereas gay activists look to him not only for intellectual inspiration but also for a compelling example of political resistance. Halperin rescues Foucault from the endless nature-versus-nurture debate over the origins of homosexuality and argues that Foucault's decision to treat sexuality not as a biological or psychological drive but as an effect of discourse, as the product of modern systems of knowledge and power represents a crucial political breakthrough for lesbians and gay men. Halperin explains how Foucault's radical vision of homosexuality as a strategic opportunity for self-transformation anticipated the new anti-assimilationist, anti-essentialist brand of sexual identity politics practiced by contemporary direct-action groups such as ACT UP. Halperin also offers the first synthetic account of Foucault's thinking about gay sex and the future of the lesbian and gay movement, as well as an up-to-the-minute summary of the most recent work in queer theory. "Where there is power, there is resistance," Michel Foucault wrote in The History of Sexuality, Volume I. Erudite, biting, and surprisingly moving, Saint Foucault represents Halperin's own resistance to what he views as the blatant and systematic misrepresentation of a crucial intellectual figure, a misrepresentation he sees as dramatic evidence of the continuing personal, professional, and scholarly vulnerability of all gay activists and intellectuals in the age of AIDS.
