This paper discusses identification and estimation of causal intensive margin effects. The causal intensive margin effect is defined as the treatment effect on the outcome of individuals with a positive outcome irrespective of whether they are treated or not, and is of interest for outcomes with corner solutions. The main issue is to deal with a potential selection problem that arises when conditioning on positive outcomes. We propose using difference-in-difference methods - conditional on positive outcomes - to estimate causal intensive (...) margin effects. We derive sufficient conditions under which the difference-in-difference estimator identifies the causal intensive margin effect. We apply the methodology to estimate the causal intensive margin effect of reaching the full retirement age on working hours. (shrink)

Technological revolutions are dissected into three stages: the introduction stage, the permeation stage, and the power stage. The information revolution is a primary example of this tripartite model. A hypothesis about ethics is proposed, namely, ethical problems increase as technological revolutions progress toward and into the power stage. Genetic technology, nanotechnology, and neurotechnology are good candidates for impending technological revolutions. Two reasons favoring their candidacy as revolutionary are their high degree of malleability and their convergence. Assuming the emerging technologies develop (...) into mutually enabling revolutionary technologies, we will need better ethical responses to cope with them. Some suggestions are offered about how our approach to ethics might be improved. (shrink)

This article advances theory on social movements’ strategic adaptation to political opportunity structures by incorporating a narrative perspective. Our theory explains how people acquire and use knowledge about political opportunity structures through storytelling about the movement’s past, present, and imagined future. The discussion applies the theory in an ethnographic case study of the climate movement’s mobilization around the UN Climate Summit in Paris, 2015. This analysis demonstrates how a dominant narrative of defeat about the prior protest campaign in Copenhagen, 2009 (...) shaped the strategizing process. While those who experienced Copenhagen as a success preferred strategic continuity, those who experienced defeat developed a “Copenhagen narrative” to advance strategic adaptation by projecting previously experienced threats and opportunities onto the Paris campaign. Yet by relying on a retrospective narrative, movement actors tended to overlook emerging political opportunities. We demonstrate that narrative analysis is a useful tool for understanding the link between structure and agency in social movements and other actors affected by (political) opportunity structures.

This cutting edge volume provides an overview of the dynamic new field of cyberphilosophy – the intersection of philosophy and computing.

1. Tout système juridique est production d’une histoire et d’une culture politiques déterminée, qui lui ont donné une organisation spécifique. Parler des limites de telles organisations peut s’entendre en deux sens, qui interagissent: premièrement, elles peuvent servir à différencier ces systèmes par rapport à d’autres ordres normatifs. Secondement, elles désignent ce que, par sa texture, le droit est hors d’état de réussir. 2. On comprend le concept de système comme une organisation aux structures différenciées de textes, de normes, d’acteurs. Ce (...) qui caractérise un système est son autoréférentialité et ses modes de clôture et ses modes d’ouverture. 3. Concernant la limite dans le second sens, on observera que la normativité comme mode d’action propre au droit le met souvent dans l’incapacité d’assumer pleinement les tâches de régulation qui lui sont confiées. Il s’agit d’une part d’une limite factuelle: celle de la technicité et du volume de ces tâches. D’autre part, la nécessité de plus en plus fréquente de prendre en compte les circonstances individuelles concrètes de l’application entraîne une légistique de diminution de la densité normative et, par conséquent, de déplacer une épistémologie fondée sur la répétition en direction de l’innovation. 4. Ces deux facteurs notamment font du droit un univers qui ne peut plus prétendre à une complétude cohérente: c’est un univers en constante évolution, qui exige pour sa mise en œuvre, de manière continue, l’apport d’informations provenant de son environnement. Ces apports circulent dans les modes d’ouverture du droit—la diminution de la densité normative et le recours à des expertises, des savoirs, des déontologies extérieures. Cependant, en vertu de l’autoréférentialité du droit, ces apports doivent être sélectionnés et juridicisés pour être intégrés dans le système juridique et préserver ainsi sa clôture. Il y a là une double programmation à respecter: la sélection doit d’une part respecter le cadre normatif du droit et de l’autre porter sur un choix correspondant aux attentes sociales qu’il s’agit de convaincre de son bien-fondé. Les limites du droit par rapport à d’autres ordres normatifs est ainsi définie par l’ordre juridique lui-même, dans le respect de cette double programmation. 5. Ce système a des présupposés politiques, culturels et historiques qui empêchent d’élaborer sans autre une essence du droit, valable urbi et orbi: notamment séparation des pouvoirs et liberté d’expression. Il n’est même pas certain qu’il puisse perdurer. En particulier, l’internalisation croissante du droit n’est guère conciliable avec son organisation telle que l’Occident l’a conçue. En outre, de plus en plus le droit devient l’objet d’une normativité supérieure, au nom de laquelle il est lui-même jugé: c’est le phénomène de l’économisation du droit. (shrink)

The standard interpretation of the imitation game is defended over the rival gender interpretation though it is noted that Turing himself proposed several variations of his imitation game. The Turing test is then justified as an inductive test not as an operational definition as commonly suggested. Turing's famous prediction about his test being passed at the 70% level is disconfirmed by the results of the Loebner 2000 contest and the absence of any serious Turing test competitors from AI on the (...) horizon. But, reports of the death of the Turing test and AI are premature. AI continues to flourish and the test continues to play an important philosophical role in AI. Intelligence attribution, methodological, and visionary arguments are given in defense of a continuing role for the Turing test. With regard to Turing's predictions one is disconfirmed, one is confirmed, but another is still outstanding. (shrink)

The capacity and availability of computers has been increasing exponentially, and people are connected with others around the world in ways unparalleled in history. The web is J.S. Mill's dream machine to the extent that it enhances people's freedom of expression, pursuit of projects, and interaction with others. But, freedom can come at a cost to justice, and we need to be cautious when confronting concentrations of power and limitations of access in cyberspace as well as understanding some special features (...) of cyberspace such as the invisibility factor and the unreality factor. Ultimately, the freedom of cyberspace may provide the best defense of justice in cyberspace. (shrink)

A ciência fenomenológica procura tratar os fenômenos como puras possibilidades. Tudo o que se doa para a consciência tem a possibilidade de ser descrito tal e qual se mostra por si mesmo numa intuição. O sujeito transcendental é o fundamento receptivo para o que é dado e, é dele, que partem os raios intencionais, dos quais os fenômenos ganham um sentido de ser de algo. Deus para ter sentido de “Deus” precisa ser para um sujeito. Mas, como Deus se doa? (...) Ele não é tal como os objetos que são dados de imediato para a consciência, mas mediado por uma teleologia da própria razão. O presente artigo se propõe pensar no tratamento que Husserl dá a sua fenomenologia como metafisica, partindo da subjetividade transcendental e destacando se “Deus” não excede ou seria outro fundamento ao lado do ego puro. A partir daí, procura-se ressaltar como o “fenômeno Deus” aparece no seu sistema fenomenológico, verificando como isso se dá em seus escritos inéditos apresentados por Jocelyn Benoist e a abertura para uma fenomenologia metafísica com Jean Luc-Marion.

Computer and information ethics, as well as other fields of applied ethics, need ethical theories which coherently unify deontological and consequentialist aspects of ethical analysis. The proposed theory of just consequentialism emphasizes consequences of policies within the constraints of justice. This makes just consequentialism a practical and theoretically sound approach to ethical problems of computer and information ethics.

This paper presents the principal findings from a three-year research project funded by the US National Science Foundation on ethics of human enhancement technologies. To help untangle this ongoing debate, we have organized the discussion as a list of questions and answers, starting with background issues and moving to specific concerns, including: freedom & autonomy, health & safety, fairness & equity, societal disruption, and human dignity. Each question-and-answer pair is largely self-contained, allowing the reader to skip to those issues of (...) interest without affecting continuity. (shrink)

Nanoethics seeks to examine the potential risks and rewards of applications of nanotechnology. This up-to-date anthology gives the reader an introduction to and basic foundation in nanotechnology and nanoethics, and then delves into near-, mid-, and far-term issues. Comprehensive and authoritative, it: -/- - Goes beyond the usual environmental, health, and safety (EHS) concerns to explore such topics as privacy, nanomedicine, human enhancement, global regulation, military, humanitarianism, education, artificial intelligence, space exploration, life extension, and more -/- -Features contributions from forty (...) preeminent experts from academia and industry worldwide, reflecting diverse perspectives -/- -Includes seminal works that influence nanoethics today -/- -Encourages an informed, proactive approach to nanoethics and advocates addressing new and emerging controversies before they impede progress or impact our welfare -/- This resource is designed to promote further investigations and a broad and balanced dialogue in nanoethics, dealing with critical issues that will affect the industry as well as society. While this will be a definitive reference for students, scientists in academia and industry, policymakers, and regulators, it's also a valuable resource for anyone who wants to understand the challenges, principles, and potential of nanotechnology.

The precautionary principle (PP) is thought by many to be a useful strategy for action and by many others useless at best and dangerous at worst. We argue that it is a coherent and useful principle. We first clarify the principle and then defend it against a number of common criticisms. Three examples from nanotechnology are used; nanoparticles and possible health and environmental problems, grey goo and the potential for catastrophe, and privacy risks generated by nanoelectronics.

Many have claimed that split-brain patients are actually two persons. I maintain that both the traditional separation argument and the more recent sophistication argument for the two persons interpretation are inadequate on conceptual grounds. An autonomy argument is inadequate on empirical grounds. Overall, theoretical and practical consequences weigh heavily in favor of adopting a one person interpretation.

A series of imitation games involving 3-participant (simultaneous comparison of two hidden entities) and 2-participant (direct interrogation of a hidden entity) were conducted at Bletchley Park on the 100th anniversary of Alan Turing’s birth: 23 June 2012. From the ongoing analysis of over 150 games involving (expert and non-expert, males and females, adults and child) judges, machines and hidden humans (foils for the machines), we present six particular conversations that took place between human judges and a hidden entity that produced (...) unexpected results. From this sample we focus on features of Turing’s machine intelligence test that the mathematician/code breaker did not consider in his examination for machine thinking: the subjective nature of attributing intelligence to another mind.

Tout ce qui n’est pas reconnu par le droit comme norme juridique est traité par lui comme un fait—normes sociales, connaissances scientifiques, mœurs, événements, etc. Le droit, système autoréférentiel, institue les compétences et les procédures par lesquelles une assertion quelconque, portant sur des faits, devient une norme juridique. Le présent texte analyse les différents lieux de passage par lesquels des faits peuvent ainsi être reconnus par le droit comme normes juridiques. Il analyse d’abord la réception et la construction des faits (...) à considérer comme pertinents au regard de la norme applicable. Il introduit ensuite le concept de notions juridiques indéterminées, dont le sens ne peut être concrétisé que par référence à des faits de toute nature, ce qui requiert une argumentation propre à justifier cette référence. Les faits sont donc construits avant qu’une autorité instituée par le droit décide de leur donner la forme abstraite d’une norme juridique. Cette construction va être structurée comme un récit, dont la cohérence doit être assurée par référence à des schémas tirés de l’expérience sociale, de telle manière qu’elle puisse être acceptée comme raisonnable par la collectivité. Le juge comme le législateur apparaissent alors sous la double face d’une fonction juridique et d’un individu plongé dans la société, ce qui les met en mesure faire du droit avec des faits en les comprenant l’un et les autres.

Born in the fifth century BCE, Plato was one of the primary thinkers of Classical Greece. A mathematician, scientist, and philosopher, Plato is considered to be a foundational figure in Western thought.

Computing plays an important role in genetics (and vice versa).Theoretically, computing provides a conceptual model for thefunction and malfunction of our genetic machinery. Practically,contemporary computers and robots equipped with advancedalgorithms make the revelation of the complete human genomeimminent – computers are about to reveal our genetic soulsfor the first time. Ethically, computers help protect privacyby restricting access in sophisticated ways to genetic information.But the inexorable fact that computers will increasingly collect,analyze, and disseminate abundant amounts of genetic informationmade available through the (...) genetic revolution, not to mentionthat inexpensive computing devices will make genetic informationgathering easier, underscores the need for strong and immediateprivacy legislation.

Résumé La localisation des implantations des grands éléments d’infrastructure collective pose des problèmes de légitimation juridique spécifique. Ils délimitent en effet plusieurs territoires distincts en fonction de la nature des impacts qu’ils provoquent, lesquels, chacun, sont soumis à leurs propres législations et rentrent dans les compétences d’autorités différentes, y compris celle dont dépend la décision sur l’infrastructure envisagée. De telles situations normatives complexes empêchent la sémantisation légitimante que le droit est censé assurer dans les décisions de l’appareil étatique: elle sera (...) toujours partielle, voire lacunaire. Les compensations ne peuvent être que procédurales, et celles-ci sont insuffisantes à atteindre l’idéal postulé par le principe de légalité des activités publiques. Mais il ne peut en aller autrement pour ces infrastructures. (shrink)

A fenomenologia, como método filosófico, consiste primeiramente numa mudança de atitude, do “olhar natural” para o “ver essencial”. O caminho fenomenológico se inicia quando um fenômeno se mostra para a consciência segundo algum modo descritivo. Com a redução dos pressupostos ou interpretações, a fenomenologia se propõe a descrever o dado puro, a essência do que se dá em aparição. Numa descrição literária, podemos entender esse objetivo fenomenológico como a descrição do conhecimento da feitiçaria, ordenada por Carlos Castaneda em suas experiências (...) incomuns de percepção. No presente artigo, pretendemos aproximar alguns pontos em comum entre feitiçaria e fenomenologia. Além do próprio Castaneda fazer referência direta aos conceitos fenomenológicos e utilizar seu método de descrição, o artigo mostra uma aproximação com o “ver”, que é o objetivo tanto do fenomenólogo quanto do feiticeiro.

In this paper I argue for a computational theory of thinking that does not eliminate the mind. In doing so, I will defend computationalism against the arguments of John Searle and James Fetzer, and briefly respond to other common criticisms.
