Video games are popular and ubiquitous aspects of human culture, but their relationships to psychological and neurophysiological traits have yet to be analyzed in social-evolutionary frameworks. We examined the relationships of video game usage, motivations, and preferences with autistic and schizotypal traits and two aspects of neurophysiology, reaction time and targeting time. Participants completed the Autism Quotient, Schizotypal Personality Questionnaire, a Video Game Usage Questionnaire, and two neurophysiological tasks. We tested in particular the hypotheses, motivated by theory and previous work, (...) that: participants with higher autism scores would play video games more, and participants with higher schizotypy scores would play video games less; and autism and positive schizotypy would be associated with opposite patterns of video game use, preferences and motivations. Females, but not males, with higher autism scores played more video games, and exhibited evidence of relatively male-typical video game genre preferences and motivations. By contrast, positive schizotypy was associated with reduced video game use in both genders, for several measures of game use frequency. In line with previous findings, males played video game more than females did overall, preferred action video games, and exhibited faster reaction and targeting times. Females preferred Puzzle and Social Simulation games. Faster reaction and targeting times were associated with gaming motives related to skill development and building behavior. These findings show that gaming use and patterns reflect aspects of psychology, and gender, related to social cognition and imagination, as well as aspects of neurophysiology. More generally, the results suggest that video game use is notably affected by levels of autistic and schizotypal traits, and that video games may provide an evolutionarily novel medium for imaginative play in which immersive play experiences can be decoupled from social interaction.

In aggressive interactions, animals often use a discrete set of signals, while the properties being signalled are likely to be continuous, for example fighting ability or value of victory. Here we investigate a particular model of fighting which allows for conventional signalling of subjective resource value to occur. The result shows that neither perfect nor no signalling are evolutionarily stable strategies in the model. Instead, we find ESSs in which partial information is communicated, with discrete displays signalling a range of (...) values rather than a precise one. The result also indicates that communication should be more precise in conflicts over small resources. Signalling strategies can exist in fighting because of the common interest in avoiding injuries, but communication is likely to be limited because of the fundamental conflict over the resource. Our results reflect a compromise between these two factors. Data allowing for a thorough test of the model are lacking; however, existing data seem consistent with the obtained theoretical results.

L’objet de la présente recherche est d’interroger les mérites de la théorie utilitariste relative aux faillites personnelles, qui est dominante dans la littérature juridique depuis que le courant Law and Economics a gagné en importance. Nous démontrons que l’argumentation utilitariste, qui est assignée aux doctrines de l’acquittement des dettes personnelles par les spécialistes de Law and Economics travaillant dans le domaine du droit des faillites, soulève des questions normatives de taille et créée des tensions quand il s’agit de décrire le (...) phénomène. Ces deux problèmes invitent les théoriciens à proposer des modèles alternatifs pour décrire les conditions dans lesquelles nos systèmes juridiques soulagent les dettes des individus qui ne sont pas en mesure de les honorer. Dans notre ouvrage à paraître, The Virtue of Bankruptcy, nous embrassons ce projet. Ici, nous proposons une étape préliminaire à ce projet plus ambitieux en démontrant que les théories utilitaristes sur lesquelles s’appuient les contributions les plus importantes de la littérature sur la question à ce jour sont perfectibles lorsqu’il s’agit de comprendre les raisons et les circonstances dans lesquelles il est possible d’offrir un nouveau départ à ceux qui n’ont pas respecté leurs obligations financières.

Brentano’s use of the expression ‘intentional inexistence’ poses a considerable terminological problem. This is due not only to the expressions ‘intentional’ and ‘inexistence’ contained in it. The biggest hurdle is the liberal use of the expression ‘object’, which is encouraged by Brentano’s notion of intentional inexistent (or immanent) objects. Carlo Ierna tries to meet this problem with a strategy that allows to hold on to the notion of intentional inexistence without accepting immanent objects. The originality of his interpretation lies, as (...) I will show in my commentary, in the fact that it tries to achieve its goal by terminological measures alone. Following the same line, I will argue that Brentano’s self-correction, made in the second edition of his Psychology, can also be interpreted in this context as a terminological move. (shrink)

The most pressing issues of the twenty-first century—climate change and persistent hunger in a world of food surpluses, to name only two—are not problems that can be solved from within individual disciplines, nation-states, or cultural perspectives. They are predicaments that can only be resolved by generating sustained and globally robust coordination across value systems. The scale of the problems and necessity for coordinated global solutions signal a world historical transit as momentous as the Industrial Revolution: a transition from the predominance (...) of technical knowledge to that of ethical deliberation. This volume brings together leading thinkers from around the world to deliberate on how best to correlate worth (value) with what is worthwhile (values), pairing human prosperity with personal, environmental, and spiritual flourishing in a world of differing visions of what constitutes a moral life. Especially in the aftermath of what is now being called the Great Recession, awareness has mounted of the imperative to question the modern divorce of economics from ethics. While the domains of economics and ethics were from antiquity through at least the eighteenth century understood in many cultures to be coterminous and mutually entailing, the modern assumption has been that the goal of maximizing human prosperity and the aim of justly enhancing our lives as persons and as communities were functionally and practically distinct. Working from a wide array of perspectives, the contributors to this volume offer a set of challenges to the assumed independence of the quantitative and qualitative dimensions of human and planetary well-being. Reflecting on the complex interrelationship among economics, justice, and equity, the book resists "one size fits all" approaches and struggles to revitalize the marriage of economics and ethics by activating cultural differences as the basis of mutual contribution to shared human flourishing. The publication of this important collection will stimulate or extend critical debates among scholars and students working in a number of disciplines in the social sciences and humanities, including philosophy, history, environmental studies, economics, and law.

Conventional wisdom has it that many intriguing features of indicative conditionals aren’t shared by subjunctive conditionals. Subjunctive morphology is common in discussions of wishes and wants, however, and conditionals are commonly used in such discussions as well. As a result such discussions are a good place to look for subjunctive conditionals that exhibit features usually associated with indicatives alone. Here I offer subjunctive versions of J. L. Austin’s ‘biscuit’ conditionals—e.g., “There are biscuits on the sideboard if you want them”—and subjunctive (...) versions of Allan Gibbard’s ‘stand-off’ or ‘Sly Pete’ conditionals, in which speakers with no relevant false beliefs can in the same context felicitously assert conditionals with the same antecedents and contradictory consequents. My cases undercut views according to which the indicative/subjunctive divide marks a great difference in the meaning of conditionals. They also make trouble for treatments of indicative conditionals that cannot readily be generalized to subjunctives. (shrink)

Doug Husak suggests that sometimes an actor should be deemed reckless, and not merely negligent, with respect to the risks that she knowingly created but has forgotten at the moment of action. The validity of this conclusion, he points out, depends crucially on what it means to be aware of a risk. Husak’s neutral prompt and counterfactual actual belief criteria are problematic, however. More persuasive is his suggestion that we understand belief, in this moral and criminal law context, as a (...) concept whose meaning is determined by its function as a culpability standard. Husak concludes that inadvertent actors are often less culpable than knowing-but-later-forgetful actors; this is plausible, but there are also numerous counterexamples. Holly Smith focuses on negligence cases in which an agent’s failure to notice a risk stems, not from a prior culpable choice, but from an objectionable attitude or set of attitudes. She is right to emphasize that genuine moral culpability does not depend on conscious choice. However, Smith also asserts that decisions that flow from an actor’s objectionable attitudes are only rarely culpable, because they often do not arise from a reasonably full configuration of the actor’s motives. This last requirement is, I fear, an unrealistic and unnecessarily demanding criterion of culpability. Even when many of the actor’s evaluative attitudes are inactive in Smith’s sense, the actor might deserve blame for not bringing them to bear on his decision. Michael Moore and Heidi Hurd thoroughly explore, and find deficient, H.L.A. Hart’s unexercised capacity theory of negligence. They are correct that that theory requires a further judgment: an actor’s inadvertence is culpable only if he had the capacity to have adverted if X where X is the source of the actor’s moral desert. They overstate, however, in suggesting that the capacity issue falls out of the picture once we identify that underlying desert basis. The authors also worry that if desert is grounded on an underlying vice, we lack a reliable way of ranking the different vices that might explain the actor’s inadvertence; this is not a fatal objection, however, because negligence determinations are quite feasible even in the absence of clear rankings. Moore and Hurd conclude by identifying eight distinct categories in which criminal liability for negligence is justifiable. Negligence is indeed a surprisingly complex and pluralist concept. The three articles in this symposium brightly illuminate some of the most fundamental conceptual and normative issues in the debate over whether it is just to blame and punish the negligently inadvertent.

L. Nathan Oaklander is one of the leading philosophers of time defending the tenseless or B-Theory of time. He has remained at the forefront of this field since the early 1980s and today he is arguably the most formidable opponent of the tensed or A-theory of time. Much of the direction of the debate in this field for the past twenty years or so, especially in regards to the new tenseless theory of time, has been influenced by Oaklander's work. This (...) book presents a carefully argued defense of the tenseless theory of time. The topics discussed include: the ontology of A- and B-theories of time; presentism; the open future theory; the A/B theory; defending the B-theory of time; temporal experience; temporal semantics; and time, identity, responsibility, and freedom.

Port of Culture is a showcase of the images from a three year photographic project undertaken by photographer Pete Carr to capture the city of Liverpool in a different light. Award-winning photographer Carr is a specialist in HDR a technique that enables photographers to record a greater range of tonal detail than any camera could capture in a single photo, producing a 'painting-like' quality to the image. The end result is an incredible dynamic range of images capturing the many (...) moods of the city - from scenes of protests at the arrival of Condoleezza Rice, to local architecture old and new. Visually stunning, Port of Culture reveals the astonishing creativity of this young photographer while providing a wholly refreshing and entrancing take on a city evolving in front of our eyes.

We all seem to think that we do the acts we do because we consciously choose to do them. This commonsense view is thrown into dispute by Benjamin Libet's eyebrow-raising experiments, which seem to suggest that conscious will occurs not before but after the start of brain activity that produces physical action.

Emerging research on the subject of happiness-in psychology, economics, and public policy-reawakens and breathes new life into long-standing philosophical questions about happiness. By analyzing this research from a philosophical perspective, Lorraine L. Besser is able to weave together the contributions of other disciplines, and the result is a robust, deeply contoured understanding of happiness made accessible for nonspecialists. This book is the first to thoroughly investigate the fundamental theoretical issues at play in all the major contemporary debates about happiness, and (...) it stands out especially in its critical analysis of empirical research. The book's coverage of the material is comprehensive without being overwhelming. Its structure and pedagogical features will benefit students or anyone studying happiness for the first time: Each chapter opens with an initial overview and ends with a summary and list of suggested readings.

A weak form of intuitionistic set theory WST lacking the axiom of extensionality is introduced. While WST is too weak to support the derivation of the law of excluded middle from the axiom of choice, we show that beefing up WST with moderate extensionality principles or quotient sets enables the derivation to go through.

Originally published in 1914, this book examines the French Voluntarist school of philosophy and the key ways in which it differs from the Pragmatists. Stebbing argues that Voluntarism and Pragmatism both prove inadequate in their definition of truth, and suggests that an acknowledgment of the 'non-existential character of truth' is needed. This book will be of value to anyone with an interest in philosophy.

Written with the general reader in mind, this collection will prove useful by both scholar and student, and will lead the general reader to encounter one of the ...
