I explore philosophically the phenomenon of home wireless networks as used to share broadband Internet connections. Because such networks are frequently unsecured, third parties can use them to access the Internet. Here I consider carefully whether this kind of behaviour should be properly called theft. I begin with a brief non-technical introduction to 802.11 wireless networks. Subsequently, I present a four part argument – appealing to the unsecured nature of the networks discussed, entrenched software and hardware behaviours, trespass law, (...) and the openness of ‹public park’ spectrum – suggesting that this kind of behaviour is permissible and should not be construed as theft. Substantively, I conclude that, despite the quite compelling considerations that these arguments bring to bear, this behaviour is theft. Additionally, I draw attention to significant flaws in the design and implementation of wireless technology (specifically in the out-of-the-box configuration for wireless access points and in the wireless connectivity of early versions of Windows XP) that facilitate the intentional and unintentional theft of Internet bandwidth. I suggest some simple mechanisms that could be incorporated into the technology which would serve to remove the ethical ambiguity in its usage by third parties, including adding the ability for a network owner to explicitly mark her network as not for public use,␣and changes to default hardware and software behaviours. I conclude by encouraging increased use of value-sensitive design practices in the development of future wireless technologies. (shrink)

Most of us have had the experience of running into a friend of a friend far away from home - and feeling that the world is somehow smaller than it should be. We usually write off such unlikely encounters as coincidence, even though it seems to happen with uncanny frequency. According to a handful of physicists at Los Alamos and other cutting-edge research labs around the world, it turns out that this 'small-world' phenomenon is no (...) coincidence at all. Rather, it is a manifestation of a hidden and powerful design that binds the world together. In SMALL WORLD, Mark Buchanan tells the story of how a stunning discovery in complexity science is revolutionising the way we understand networks. The Internet, the brain, power-grids and the global economy are all networks that seem to have evolved a 'small-world' geometry - with properties independent of the nature of the things themselves. SMALL WORLD argues that this underlying pattern may be one of nature's greatest design tricks, and the book shows us - concisely and engagingly - how scientists are putting this new insight to work. The discovery promises to change the way we see the web of relationships that weaves our lives together. What's more, it may well provide the foundation for a new kind of physics that searches for the laws not of substance, but of pure form. (shrink)

I argue that there is a cognition condition on intention and intentional action. If an agent is doing A intentionally, she has knowledge in intention that he is doing A. If an agent intends to do A, she has knowledge in intention that she is going to do A. In both cases, the agent has knowledge of eventual success, in this sense: she knows that it will be no accident if she ends up having done A. In both cases, the (...) agent’s knowledge is of what is happening, or what is going to happen, in the world; it is not knowledge merely of her state of mind. This knowledge is practical: it the cause of what it understands; without it what is happening, or what is going to happen, is not an intentional action, and any practical thought of the agent’s about what is happening, or what is going to happen, does not hit the heights of intention. I demonstrate that famous examples (from Davidson and Bratman) purporting to show that the cognition condition should be rejected (or its content or scope weakened) are ineffective, because they trade on confusions about the different kinds of failure to which intentional action may be susceptible, confusions remedied via reflection on the structure of intentional action. I show that the cognition condition is grounded not in reflection about the directions of fit and guidance of different kinds of mental states, nor in the indicative content of linguistic expressions of intention, but in the calculative and temporal structure of intentional action itself.

Recent work on testimony has raised questions about the extent to which testimony is a distinctively second-personal phenomenon and the possible epistemic significance of its second-personal aspects. However, testimony, in the sense primarily investigated in recent epistemology, is far from the only way in which we acquire knowledge from others. My goal is to distinguish knowledge acquired from testimony (learning from being told) from knowledge acquired from teaching (learning from being taught), and to investigate the similarities and differences between (...) the two with respect to the interpersonal dimensions of their structures.

Ethical decision-making is a multi-faceted phenomenon, and our understanding of ethics rests on diverse perspectives. While considering how leaders ought to act, scholars have created integrated models of moral reasoning processes that encompass diverse influences on ethical choice. With this, there has been a call to continually develop an understanding of the micro-level factors that determine moral decisions. Both rationalist, such as moral processing, and non-rationalist factors, such as virtue and humanity, shape ethical decision-making. Focusing on the role of (...) moral judgement and moral intent in moral reasoning, this study asks what bearings a trait of mindfulness and a sense of moral responsibility may have on this process. A survey measuring mindfulness, moral responsibility and moral judgement completed by 171 respondents was used for four hypotheses on moral judgement and intent in relation to moral responsibility and mindfulness. The results indicate that mindfulness predict moral responsibility but not moral judgement. Moral responsibility does not predict moral judgement, but moral judgement predicts moral intent. The findings give further insight into the outcomes of mindfulness and expand insights into the models of ethical decision-making. We offer suggestions for further research on the role of mindfulness and moral responsibility in ethical decision-making. (shrink)

I trace the development of one aspect of Fred Stoutland’s thought about action by considering the central role given by contemporary philosophy of action to bodily movement. Those who tell the so-called standard story of action think that actions are bodily movements (arm raisings, leg bendings, etc.) caused by beliefs and desires, that cause further effects in the world (switch flippings, door movements, etc.) in virtue of which they can be described (as flippings of switches, shuttings of doors, etc.). (...) Those who hold a disjunctive conception of bodily movement think that actions are bodily movements that involve intentions essentially, but they too think that when an agent raises a glass, there is an action (an arm raising, perhaps) that causes a distinct event (a glass rising), in virtue of which the action (= the bodily movement) may be redescribed as a raising of a glass. Against both views, it might be held that actions may constitutively involve the changes wrought on their patients—that action is, in the first instance, transaction. But if action consists fundamentally not in an agent’s moving herself, but in her moving (or otherwise changing) something else, then how should we think about the nature and philosophical significance of bodily movement?

Constructivism comes in a number of forms. Some are models of learning which involve few, if any, startling epistemological claims. On the other hand, what has been promoted as ‘radical constructivism’ holds that our concepts cannot be related directly to an external reality, and that claims for the objectivity of knowledge are therefore unjustified. This standpoint is an anti-realist version of evolutionary epistemology. I argue that it relies on a mistaken interpretation of the Darwinian theory of evolution by natural selection, (...) and that its application of this model to the relation between knowledge and the world is also mistaken.

GS 341 is one of the most familiar of Nietzsche’s writings. This article proposes a new reading that stands in contrast with most English-language Nietzsche scholarship. The text presents a communication and its reception. A ‘demon’ makes an announcement, and a hearer responds in one way or another. But there is also another narrative altogether, whose conceptual vocabulary comes from a dynamic world-view. In this an interaction of forces leads to a new situation. If the hearer is not crushed (...) by the ‘greatest weight’, there must be an inner force that counteracts its impact. I argue that what Nietzsche calls amor fati is a state that allows our drives to achieve full expression, and so makes possible a collective strength able to withstand the greatest impact. The final sentence refers to a “confirmation and sealing”. What happens is that the demon’s message makes an impression on the receptive hearer. For Nietzsche this is a working metaphor, not a turn of phrase. In a draft from this period he writes: “Let us stamp the image of eternity on our life!” That sudden and forceful act, embodying an evaluative judgement, is the event that GS 341 is all about.

This paper discusses a number of critical ethical problems that arise in interactions between queer patients and health care professionals attending them. Using real-world examples, we discuss the very practical problems queer patients often face in the clinic. Health care professionals face conflicts in societies that criminalise same sex relationships. We also analyse the question of what ought to be done to confront health care professionals who propagate falsehoods about homosexuality in the public domain. These health care professionals are (...) more often than not motivated by strong religious convictions that conflict with mainstream medical opinion on homosexuality. We argue that they ought to be held accountable for their conduct by their professional statutory bodies, given that they abuse their professional standing to propagate sectarian views not representative of their profession. Lastly, we propose that medical schools have special responsibilities in training future health care professionals that will enable them to respond professionally to queer patients seeking health care.

Postmodernism and health economics are both concerned with questions about choices and values, risk and uncertainty. Postmodernists seek to respond to such questions in the context of a world of uncoordinated and often contradictory chances, a world devoid of clear-cut standards. Health economics seeks to respond using the constructs of modernity, including the application of reason to generate better order. In this article we present two sorts of voice. First we introduce postmodernism and those seeking to contribute to (...) economics from a postmodern perspective. Second, we consider critics of a prevalent neo-classicism within health economics both from outside that paradigm and from those more closely associated with it. It is increasingly evident that (health) economics, as presently constituted, is failing both in its descriptive powers and its prescriptive possibilities. Postmodernism offers not just an alternative theoretical approach but the possibility of both expanding the scope of health economics and grounding it more appropriately in the everyday experience of those engaging with health systems.

This work, an initiative of the University of French Polynesia, Tahiti, showcases research collaboration between small island universities in the Pacific. It addresses a number of 'big issues' for Oceania which are also big issues for the world, concerning the biosphere and human society, sustainable development and well-being. The authors seek to create an ecosystem of knowledge through a dialogue, in English and French, between the natural sciences, the social sciences and the humanities. The work also brings into (...) perspective academic and traditional knowledge, with a view to enhancing cultural and agricultural practices and the development of public policy. Climate change, environmental degradation and food security are key questions for survival. How can the preservation of cultural heritage, the transmission of native languages and the integration of traditional knowledge into formal education contribute to a harmonious future? How is the phenomenon of violence relevant to an understanding of history, interpersonal relations and social inclusiveness, including for women in the political sphere? The Tongan-Fijian writer Epeli Hau'ofa described Oceania imaginatively as a 'Sea of Islands'. This volume sees Pacific islands as being interconnected in ways beyond imagining, in which nowhere is remote, where the peripheral has become a decentred centre. (shrink)

In this paper, we analyse the recent rapid growth of ‘binge’ drinking in the UK. This means the rapid consumption of large amounts of alcohol, especially by young people, leading to serious anti-social and criminal behaviour in urban centres. British soccer fans have often exhibited this kind of behaviour abroad, but it has become widespread amongst young people within Britain itself. Vomiting, collapsing in the street, shouting and chanting loudly, intimidating passers-by and fighting are now regular night-time features of many (...) British towns and cities. A particularly disturbing aspect is the huge rise in drunken and anti-social behaviour amongst young females. Increasingly, policy makers in the West are concerned about how not just to regulate but to alter social behaviour. Smoking and obesity are obvious examples, and in the UK ‘binge’ drinking has become a focus of acute policy concern. We show how a simple agent based model approach, combined with a limited amount of easily acquired information, can provide useful insights for policy makers in the context of behavioural regulation. We show that the hypothesis that the rise in binge drinking is a fashion-related phenomenon, with imitative behaviour spreading across social networks, is sufficient to account for the empirically observed patterns of binge drinking behaviour. The results show that a small world network, rather than a scale-free or random one, offers the best description of the data. (shrink)

The issue of violence has been approached differently in various disciplines of social sciences. The ethical approach to the discourse of violence has often been ignored and thus need our attention. How the “body-subject” experiences the presence of violence as a ubiquitous phenomenon prevalent in the lived-world? I have made a distinction between grand narratives and small narratives1 within the discourse of violence in order to comprehend the operationality of violence in the inter-subjective world. My concern (...) in this paper is that the various discourses of social sciences on violence have not dealt with this issue adequately. Violence has been understood so far by social sciences in terms of finding causes and consequences of the event of violence rather than as an experience that affects the intentionality of an individual. Violence needs to be looked at as a phenomenon rather than as an abstract concept. Violence is experienced by the subject in one’s everyday existence when one is engaged with the “commonsense world”. How an individual makes sense of the lived-world and one’s existence within the pre-given structures of the lived-world? The prominence has been given to the existential/ first person perspective of an individual as an experiencing self and also as an acting self. To have the wholistic picture of violence one not only has to look at the various structures of the lived-world but also at different relations that an individual share with the pre-given inter-subjective world.

From a problem that concerned only a small number of people, migration has become a constant concern both nationally and internationally. The concrete realities in different regions have become over time subjects of analysis and reflection in order to find solutions that meet the many theoretical and practical issues raised by migration. In Romania people are increasingly discussing about migration and its implications on all sectors of human life. In this context, the Romanian Orthodox Church is called by his (...) priests, to contribute to the integration of people of other nationalities, cultures and beliefs that are established here and at the same time, to help her spiritual children living and working in different parts of the world to preserve and to confess their Orthodox Christian faith. Moreover, it should take care of their families in the country and to contribute to the education of children, whose parents are away, in the spirit of the Christian tradition. (shrink)

Drama, at least according to the Aristotelian view, is effective inasmuch as it successfully mirrors real aspects of human behavior. This leads to the hypothesis that successful dramas will portray fictional social networks that have the same properties as those typical of human beings across ages and cultures. We outline a methodology for investigating this hypothesis and use it to examine ten of Shakespeare’s plays. The cliques and groups portrayed in the plays correspond closely to those which have been observed (...) in spontaneous human interaction, including in hunter-gatherer societies, and the networks of the plays exhibit “small world” properties of the type which have been observed in many human-made and natural systems.

Abraham Pais's Subtle Is the Lord was a publishing phenomenon: a mathematically sophisticated exposition of the science and the life of Albert Einstein that reached a huge audience and won an American Book Award. Reviewers hailed the book as "a monument to sound scholarship and graceful style", "an extraordinary biography of an extraordinary man", and "a fine book". In this groundbreaking new volume, Pais undertakes a history of the physics of matter and of physical forces since the discovery of (...) x-rays. The book attempts to relate not only what has happened over the last hundred years but why it happened the way it did, what it was like for those scientists involved, and how what at the time may have seemed a series of bizarre or unrelated events, now with hindsight emerges as a logical sequence of events. Pais, a noted physicist, was personally involved in many of the developments he describes, and thus Inward Bound, like his earlier book, is filled with unique insights into the world of big and small physics. Between 1895 and 1983, the period he covers, the smallest distances explored have shrunk a hundred millionfold, Pais notes. Along this incompletely traveled "road inward," scientists have established markers that later generations will rank among the principal monuments of the twentieth century. In alternating technical and nontechnical sections, this magisterial survey richly conveys what has been discovered about the constituents of matter, the laws to which they are subject, and the forces that act on them. But the advances have certainly not come smoothly. The book shows that these have been times of progress and stagnation, of order and chaos, of clarity and confusion, of belief and incredulity, of the conventional and the bizarre; also of revolutionaries and conservatives, of science by individuals and by consortia, of little gadgets and big machines, and of modest funds and big money. About the Author: Abraham Pais is Detlev W. Bronk Professor of Physics at the Rockefeller University. The author of the prizewinning biography of Einstein now undertakes a history of modern physics.

The wave function of quantum mechanics can be understood in terms of the dispositional role it plays in the dynamics of a distribution of matter in three-dimensional space (or four-dimensional spacetime). There is more than one way, however, of specifying its dispositional role. This paper considers Suárez’s theory of ‘Bohmian dispositionalism’, in which the particles are endowed with their own ‘Bohmian dispositions’, and Simpson’s theory of ‘Cosmic Hylomorphism’, in which the particle configuration comprises a hylomorphic substance which has an intrinsic (...) power. I argue that Bohmian dispositionalism fails to capture intuitively correct counterfactuals about what would happen in Small Worlds which have only a small number of particles, but that this problem is avoided by Cosmic Hylomorphism, in which the cosmic power manifests a teleological process.

The case for the superiority of Conviction Narrative Theory (CNT) over probabilistic approaches rests on selective employment of a double standard. The authors judge probabilistic approaches inadequate for failing to apply to “grand-world” decision problems, while they praise CNT for its treatment of “small-world” decision problems. When both approaches are held to the same standard, the comparative question is murkier.

If objective physics is dependent on observer properties as Einstein showed, physical reality becomes an ‘interface reality'. Einstein's principle of observer-relativity is extended to micro motions in the observer. The resulting ‘micro relativity’ can be studied using model universes. In a classical billiard universe, the interface is characterized by ‘micro time reversals'. These time reversals cannot be ‘edited out'. They perturb every small-mass object to be observed. And they perturb every fast-moving object to be observed. The implied ‘action noise’ (...) and a ‘velocity limit', respectively, are reminiscent of Planck's constant and the speed of light , in the real world. To check whether there exists a connection with the real world, the observer temperature can be inserted into the two fundamental constants h and c. This leads to a specific value for the ‘observer diameter’ . Search for a cell class clustered around this size in the brain would amount to a ‘Privacy-of-Physics test'. Four such ‘PoP tests’ can be indicated so far. The idea that certain relational properties of the world may be as observer-private as consciousness, is therefore falsifiable. (shrink)

The cognitive, psychological and sociological mechanisms underpinning complex social relationships among small groups are a part of our primate heritage. However, among human groups, relationships persist over much greater temporal and spatial scales, often in the physical absence of one or other of the individuals themselves. This chapter examines how such individual face-to-face social interactions were ‘scaled up’ during human evolution to the regional and global networks characteristic of modern societies. One recent suggestion has been that a radical change (...) in human sociality occurred with the shift to sedentary and agricultural societies in the early Neolithic. The discussion presents the results of a focused study of the long-term development of regional social networks in the Near East, using the distribution of different forms of material culture as a proxy for the social relationships that underpinned processes of trade, exchange and the dissemination of material culture practices.

To our knowledge, this is one of the first studies to test different theoretical models of working memory in childhood based on a computerized assessment. We tested this across several countries: Argentina, Brazil, Canada, Italy, and UK. The present study addressed the wider macro-cultural context and how this impacts working memory. We used two economic indices to characterize the participating countries and ranked the countries based on the Global Index of Cognitive Skills and Educational Attainment. Children between 5 and 10 (...) years completed the same set of short-term and working memory tests. There were two main findings. First, there was a similar pattern in verbal working memory across countries, which suggests that this skill may be relatively consistent across different cultural groups. In contrast, the pattern for visuo-spatial working memory was different across countries, which may explained by cultural differences and educational rankings of the countries. The second main finding was that both a domain-general model and a domain-specific model provided a reasonably good fit with the data, there was the high relationship between the verbal and visuo-spatial working memory constructs across the countries in the latter model. Thus, it may be a more parsimonious choice to rely on a three-factor model. The data also suggest culture-similar patterns in a computerized assessment of working memory. (shrink)

For Polish Jews, Warsaw was an important center of social and cultural life. It was the biggest center of Jewish community and culture in Europe. It was also here that the greatest tragedy of this community took place, made still more dramatic by the transports of the Jews from various European and Polish cities. The Warsaw Ghetto Uprising reminds us of the egoism of the societies of the Allied powers. Similarly the lonely fight of the heroes of the Warsaw ghetto (...) reminds us of the lonely fight of the insurgents of Warsaw in 1944. Both uprisings involved the whole society. They differed only in the scale of military operations conducted and in their duration.Polish Jews, as well as the Jews from other countries, observed with deep interest the course of insurgent fights, in which a small number of Warsaw Jews saved from extermination and Jews from many European countries, liberated by the insurgents, took part. The feeling of community of fate of the Polish and Jewish nations was a phenomenon of the Warsaw Uprising in 1944; it was a harmony that was never achieved again. Jews, citizens of different countries and members of different organizations loudly demanded help for the heroic but forlorn insurgents. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Rationality and Religious Experience: The Continuing Relevance of the World's Spiritual TraditionsRonnie LittlejohnRationality and Religious Experience: The Continuing Relevance of the World's Spiritual Traditions. By Henry Rosemont, Jr.Chicago: Open Court, 2001. Pp. vii + 106.In April 2000, Henry Rosemont delivered the first Hsuan Hua Memorial Lecture at the Pacific School of Religion, Berkeley. The following year, this lecture—originally titled "Whither the World's Religions?"—was published by (...) Open Court in this small book, Rationality and Religious Experience: The Continuing Relevance of the World's Spiritual Traditions. The volume is divided into four sections: (1) the lecture itself, which has the new title "Rationality and Religious Experience"; (2) a commentary by Huston Smith; (3) response and discussion, in which Rosemont replies to Smith and takes questions from the audience; and (4) an epilogue, in which Rosemont makes revisions and expansions on the lecture based on the comments and discussion.In section 1, Rosemont makes a bold claim: "By urging everyone to approach their own text tradition afresh, and alongside others, I am assuming what many of you might find implausible, namely, that in many basic respects all sacred texts are saying the same things, and contain the same truths we can all come to believe without in any way surrendering our rationality" (p. 11). Having said this, he nonetheless does not mean that we can accept the statements of religious texts as stating factual truths, much less that they are putting forward identical descriptions of the world.Rosemont faces the epistemological difficulties of religion directly, saying that we cannot accept the statements of religious texts as factual accounts of the world. He reminds us that it is not merely the Abrahamic traditions that pose an epistemological problem for us: "It no less flies in the face of modern science to believe that the preserver god Vishnu once incarnated himself as Krishna, not merely to give counsel to the spiritual warrior Arjuna, but also, among many other exploits, to make love to 20,000 milkmaids in a single day" (p. 5). Even so, he holds that there is much truth in the sacred texts and narratives of the world's religions (pp. 31-32). As will become apparent in my later remarks, it is not altogether clear to me what sort of truth Rosemont is talking about, but it seems to be more a matter of a certain ego-reduction and a sort of mystical feeling than anything else.Rosemont recognizes not only the epistemological objections to religion, but also the moral ones. He understands the violence and suffering that has been directly and indirectly associated with religion in human history. Yet, in this connection, he says:[E]fforts to exorcise religion from the human realm because of the mischief that has been committed in its name is to throw out the baby with the bath water, and equally to suggest a third response, that there is no hope for the cross-cultural dialogues necessary for [End Page 404] the creation and maintenance of a more peaceful and just twenty-first century until and unless everyone can come to understand how an intelligent and thoroughly decent human being might come to be, or remain, a subscriber to one or another of the world's faiths.(p. 10)It is the phenomenon of spiritual experience and not the doctrine or ontology of any tradition that Rosemont finds of philosophical interest. He thinks that instead of focusing on some purported factual knowledge about the world that we are to believe directly, we should instead concentrate on the instructions that the traditions offer about how to live purposively in the world and derive nonmaterial nurturance from it. "The basis of such nurturance is religious experience" (p. 17).Rosemont begins his remarks on religious experience with a critique of Kierkegaard the purpose of which is to show that lived experience is of one piece. Rosemont attributes to Kierkegaard the position that there are distinguishable and autonomously separable spheres of existence such as the aesthetic, ethical, and spiritual. Speaking of Kierkegaard's three stages, he says that "Almost all of the world's religious traditions, especially the Asian, affirm... (shrink)

More than one researcher is currently proposing that the notion of information become an important element for defining living systems as well as for explaining conditions that make their origins possible. During the pre-biotic era, the type of compounds encountered would mainly have been very simple in nature and might have been immersed in the natural dynamic of the physical world and in processes of self-organization. It is furthermore quite possible that they formed a relationship between and among certain (...) types of processes that here we are specifically proposing as central for the emergence of cell organization. Consequently, an important initial step towards constructing a theory of biological information is to ask ourselves the question: how do biological systems process information? In this way, we will be contributing to the proposals of this paper where we seek to identify general principles that govern biological computing and that deal with biosemiotic approaches as they are defended in naturalistic normative terms.

For a finite universe of discourse, if Φ → and ~(Ψ → Φ) , then P(Ψ) > P(Φ), i.e., there is always a loss of information, there is an increase in probability, in a non reversible implication. But consider the two propositions, "All ravens are black", (i.e., "(x)(Rx ⊃ Bx)"), and "Some ravens are black" (i.e., "(∃x)(Rx & Bx)"). In a world of one individual, called "a", these two propositions are equivalent to "~Ra ∨ Ba" and "Ra & Ba" (...) respectively. However, (Ra & Ba) → (~Ra ∨ Ba) and ~[(~Ra ∨ Ba) → (Ra & Ba)]. Consequently, in a world of one individual it is more probable that all ravens are black than that some ravens are black! (shrink)

We examine data on and models of small world properties and parameters of social networks. Our focus, on tie-strength, multilevel networks and searchability in strong-tie social networks, allows us to extend some of the questions and findings of recent research and the fit of small world models to sociological and anthropological data on human communities. We offer a 'navigability of strong ties' hypothesis about network topologies tested with data from kinship systems, but potentially applicable to corporate (...) cultures and business networks.
