Dramatic advances in 3D Web technologies have recently led to widespread development of virtual world Web browsers and 3D content. A natural question is whether 3D thumbnails can be used to find one’s way about such 3D content the way that text and 2D thumbnail images are used to navigate 2D Web content. We have conducted an empirical experiment that shows interactive 3D thumbnails, which we call worldlets, improve travelers’ landmark knowledge and expedite wayfinding in virtual environments.

This paper proposes several concepts of efficient solutions for multicriteria decision problems under uncertainty. We show how alternative notions of efficiency may be grounded on different decision ‘contexts’, depending on what is known about the Decision Maker's (DM) preference structure and probabilistic anticipations. We define efficient sets arising naturally from polar decision contexts. We investigate these sets from the points of view of their relative inclusions and point out some particular subsets which may be especially relevant to some decision situations.

In this article, I wish to show the importance of the consequentialist method for the realisation of the ideal of non-domination. If, as stated by Philip Pettit, consequentialist ethics helps to better conceive republican political institutions, we then have to see how the fundamental principles of republican liberty can meet the norms traditionally associated with consequentialism. After a brief presentation of consequentialism and republican liberty (as Pettit defines it), I criticize the idea that liberty as non-domination could be included in (...) a bundle of goods that we seek to maximize. Next, I argue that we should reject the maximization of liberty as non-domination when this concept is considered as an absolute. Finally, I explore the idea of liberty as a condition for other goods, where liberty is still taken in the republican sense. These three theses are all rejected by demonstrating that the maximization of republican liberty is not really the maximization of liberty itself, but the maximization of protections granted to the individuals with the aim of defending their liberty.

Quelle est la responsabilité des intellectuels en temps de guerre? Cet article entend offrir une analyse de la pensée de Michael Walzer afin de répondre à cette question. Il s’agira d’abord de revenir sur la distinction classique, au sein des théories de la guerre juste, entre combattants et non combattants. Par la suite, il sera possible d’examiner de manière plus exacte la responsabilité des citoyens en temps de guerre, et plus particulièrement des intellectuels.

Virtual environment landmarks are essential in wayfinding: they anchor routes through a region and provide memorable destinations to return to later. Current virtual environment browsers provide user interface menus that characterize available travel destinations via landmark textual descriptions or thumbnail images. Such characterizations lack the depth cues and context needed to reliably recognize 3D landmarks. This paper introduces a new user interface affordance that captures a 3D representation of a virtual environment landmark into a 3D thumbnail, called a worldlet. Each (...) worldlet is a miniature virtual world fragment that may be interactively viewed in 3D, enabling a traveler to gain first-person experience with a travel destination. In a pilot student conducted to compare textual, image, and worldlet landmark representations within a wayfinding task, worldlet use significantly reduced the overall travel time and distance traversed, virtually eliminating unnecessary backtracking.

"Williams's masterful translation satisfies (at last!) a long-standing need. There are lots of good translations of Augustine's great work, but until now we have been forced to choose between those that strive to replicate in English something of the majesty and beauty of Augustine's Latin style and those that opt instead to convey the careful precision of his philosophical terminology and argumentation. Finally, Williams has succeeded in capturing both sides of Augustine's mind in a richly evocative, impeccably reliable, elegantly readable (...) presentation of one of the most impressive achievements in Western thought--Augustine's Confessions." --Scott MacDonald, Professor of Philosophy and Norma K. Regan Professor in Christian Studies, Cornell University. (shrink)

The Moral Nexus develops and defends a new interpretation of morality—namely, as a set of requirements that connect agents normatively to other persons in a nexus of moral relations. According to this relational interpretation, moral demands are directed to other individuals, who have claims that the agent comply with these demands. Interpersonal morality, so conceived, is the domain of what we owe to each other, insofar as we are each persons with equal moral standing. The book offers an interpretative argument (...) for the relational approach. Specifically, it highlights neglected advantages of this way of understanding the moral domain; explores important theoretical and practical presuppositions of relational moral duties; and considers the normative implications of understanding morality in relational terms. The book features a novel defense of the relational approach to morality, which emphasizes the special significance that moral requirements have, both for agents who are deliberating about what to do and for those who stand to be affected by their actions. The book argues that relational moral requirements can be understood to link us to all individuals whose interests render them vulnerable to our agency, regardless of whether they stand in any prior relationship to us. It also offers fresh accounts of some of the moral phenomena that have seemed to resist treatment in relational terms, showing that the relational interpretation is a viable framework for understanding our specific moral obligations to other people.

'Nadeau and Kafatos supply plenty of food for thought: the apparently recondite concept of non-locality, they suggest, has consequences everywhere.'--Publisher's Weekly.

Many methodologists are firmly convinced that Popper's arguments concerning the status of the rationality principle (RP) are incoherent or incompatible with the essentials of falsificationism. The present essay first shows that the accusation of incompatibility of situational logic with falsificationism does not hold up to scrutiny but then shows that Popper's arguments are nonetheless flimsy if not indefensible. For it seems that one can distinguish between two different versions of the RP in Popper's writings. If the first version is plainly (...) "objectivist" and can be characterized with Popper as empirically false, the second one is rather "subjectivist" and is not falsifiable as such. The essay shows that this second reading of the RP is the one that Popper finally adopts but that, unfortunately enough, this formulation of the RP looks more like a metaphysical statement than like an empirical law. It could then be held to be a priori valid as such, by analogy with Popper's line of argument concerning the principle of causality. If this is correct, then Popper's thesis on the empirical status of the RP is confuted. (shrink)

Alice Le Goff ,Christian Nadeau | : Ce texte constitue une introduction au dossier. Il introduit les différentes contributions en mettant en relief leurs principales orientations. Ce faisant, il propose donc une cartographie conceptuelle, forcément partielle, des enjeux associés à la notion de démocratie épistémique et des enjeux du croisement de cette notion avec celle de démocratie de contestation. En un premier temps, nous revenons sur l’apport du procéduralisme épistémique et sur les questions qu’il soulève. Ensuite, nous revenons sur (...) le néo-pragmatisme et la façon dont il permet d’envisager une justification épistémique de la démocratie. Puis nous mettons l’accent sur les enjeux d’un dialogue entre modèle républicain de la démocratie contestataire et modèle épistémique. Enfin, le texte propose un résumé du parcours proposé dans le cadre de ce dossier. | : This introduction brings out the main lines of the articles collected in the present issue. Our aim is to provide the reader with a conceptual overview of the main stakes of epistemic democracy and of its intersections with the model of contestatory democracy. First, we focus on epistemic proceduralism, its contributions and the questions it raises. Second, we emphasize the way neo-pragmatism deals with the epistemic justification of democracy. Then, we insist on the interest of a dialogue between epistemic democracy and the neo-republican model of contestatory democracy. Finally, the text sums up the path followed in that issue. (shrink)

Aesthetics in philosophy of mathematics is too narrowly construed. Beauty is not the only feature in mathematics that is arguably aesthetic. While not the highest aesthetic value, being interesting is a sine qua non for publishability. Of the many ways to be interesting, being explanatory has recently been discussed. The motivational power of what is interesting is important for both directing research and stimulating education. The scientific satisfaction of curiosity and the artistic desire for beautiful results are complementary but both (...) aesthetic. (shrink)

"I believe," André Breton said, "in the future resolution of the states of dream and reality--in appearance so contradictory--in a sort of absolute reality, or surréalité." The Surrealist movement, born in the 1920s out of the ferment of Dada, committed to revolution against bourgeois rationalism, and inspired by Freudian exploration of the unconscious, has reverberated more widely and deeply than perhaps any other art movement in our century. Its automatism, biomorphic shapes, visionary mode, and manipulation of found objects mark the (...) work of artists as different as Ernst, Miró, Magritte, and Dali. Maurice Nadeau's History of Surrealism, first published in French in 1944 and in English in 1965, has become a classic. It is both lucid and authoritative--by far the best overall account of this complex movement. Nadeau traces the evolution of Surrealism, bringing to life its many internal debates about politics and art. He relates the movement to its intellectual and artistic environment. And he provides the statements and manifestos of Breton, Aragon, Tzara, and others. (shrink)

Throughout his writings, Hayek has emphasized that a "scientistic prejudice" is working as a bad steering factor in the research for sound theories in the general field of social sciences, and especially in economics. Notwithstanding Hayek's criticism, most contemporary economists still think that they must imitate methods of physical and biological sciences in order to do good and valid science. While Hayek was first vehemently reproving this methodological choice in his early writings (for example, Hayek 1952), he was afterwards convinced (...) by Popper, as he himself acknowledges (see Hayek 1967) that the scientific method social scientists sought to transpose into their own research field was mere illusion. Consequently, Hayek rejected the confirmationist approach to economic theories and adopted a strict falsificationist one (this is very clear in the Nobel Memorial Lecture: see Hayek 1974). (shrink)

We should approach this topic with great fear and respect. It is not a merely “academic” issue. Human rights are trampled upon in the East as in the West, in the North as in the South of our planet. Granting the part of human greed and sheer evil in this universal transgression, could it not also be that Human Rights are not observed because in their present form they do not represent a universal symbol powerful enough to elicit understanding and (...) agreement?

Chemical structures are among the trademarks of our profession, as surely chemical as flasks, beakers and distillation columns. When someone sees one of us busily scribbling formulas or structures, he or she has no trouble identifying a chemist. Yet these familiar objects, which accompany our work from start to end, from the initial doodlings (Fig. I) to the final polished artwork in a publication (Fig. II), are deceptively simple. They raise interesting and difficult questions about representation. It is the intent (...) of this article to reflect upon molecular graphics. (shrink)

Cet article défend la thèse suivant laquelle le républicanisme de Machiavel doit être pensé dans le cadre théorique des tumulti, c’est-à-dire des conflits entre les grands — qui veulent dominer— et le peuple — qui veut être libre. Cela signifie d’abord que le républicanisme de Machiavel ne présuppose aucune conception compréhensive de la liberté politique ni de quelque vision du bien que ce soit. La valeur normative de la thèse du conflit tient en ce que les dissensions entre les groupes (...) sociaux sont garants de la liberté politique et de la neutralité axiologique des institutions qui favoriseront cette liberté. Cela signifie ensuite, mais il s’agit en réalité de la même affirmation, que la pensée politique de Machiavel ne doit pas être interprétée en fonction des paramètres de l’humanisme civique, qui est une forme de néo-aristotélisme sur le plan politique et éthique et dont on associe trop souvent et trop facilement les thèses au républicanisme sous prétexte qu’il en est une des origines.This article defends the claim that Machiavelli’s republicanism should be approached via the theoretical framework of tumulti, that is, the conflicts among the powerful “who want to dominate” and the people “who wants to be free”. It means that Machiavelli’s republicanism presupposes neither a comprehensive conception of political freedom, nor any vision of what the good is. The normative value of the conflict thesis lies in the fact that social dissent between the social groups secures the political freedom and the axiological neutrality of the institutions that promote this freedom. It means therefore — and it is in reality the same assertion — that Machiavelli’s political thought should not be interpreted as related to some form of civic humanism, that is, a neo-Aristotelian conception of ethics and politics, and which we too easily associate with republicanism.

1.- Introduction: articulating Hayek’s evolutionary argument with his socialist calculation dispute I completely agree with Bruce Caldwell (Caldwell 1988b: 74-75; Caldwell 1988a) that it is precisely within the conceptual and theoretical framework of the debate on the possibility of socialist calculation that Hayek definitively breaks with the standard static equilibrium approach to the market economy and finds out that the central problem of economics is related to the complex question of social coordination. From the Hayekian standpoint, this problem cannot be (...) solved without articulating a genuine theory about the role and the use of knowledge in society.1 This forms the hard core of what I will call the Hayekian theoretical argument. But one can find a much different kind of argument in Hayek, i.e. an evolutionary argument. I will characterize this argument as the Hayekian empirical argument. Hayek first exposed the essential elements of this genuine argument systematically in Law, Legislation and Liberty (see especially Hayek 1973). But in Hayek’s last book (Hayek 1988), socialism is still analyzed from this evolutionary standpoint , and as such socialism is considered by Hayek to be the major problem not only of economic theory but also, more globally, of Western civilization itself. In that book, published the year before the Soviet Union collapsed, Hayek showed himself to be absolutely confident that economic analysis could prove that socialism was not only a social blunder and a political failure, but above all a formidable scientific error. My reading of Hayek’s work is that this evolutionary argument has to be linked to the first one, which is of a more theoretical nature as far as economics is concerned. Indeed, while the evolutionary argument puts forward a completely different conceptual framework tightening the theoretical argument, it first of all displaces the gist of Hayek’s claim against socialism..

On prior's reconstruction, The master argument of diodorus contains an equivocation and so is invalid for one class of diodorean "propositions." but diodorus knew of such "propositions" and an argument in his treatment of motion can be used to bring them under the master argument's sway. Also, Despite the consensus of antiquity, The master argument does not commit diodorus to determinism, Although it commits him to non-Deterministic theses which can be easily misinterpreted as deterministic.

Ethics and Decision Making in Counseling and Psychotherapy has a distinct and timely focus on counseling as a profession. Chapters address the mental health professions, values in counseling, decision making, ethical principles, ethical standards, technology, ethical climate, and office/administrative practices. The early chapters present a foundation for ethical practice of the profession and provides solid building blocks to the more advanced perspectives in later chapters. Chapters on specialty practice are lively and contemporary overviews of these practice areas in counseling that (...) reflect more recent trends to increased differentiation of these areas of practice. Each specialty has its own chapter to allow for an extended discussion of the unique aspects of the field that provide clarity to understanding the particular ethical issues and standards that apply in each specialty. The specialty areas recognized by CACREP are included: mental health counseling; school counseling; couple, marital, and family counseling; rehabilitation counseling; addictions counseling; career counseling; and group counseling. This book is broad in its coverage of the most practiced specialties in mental health practice, and provides an efficient and effective overview of the broad scope of particular areas addressed in counseling.

The concept of spontaneous order is an important framework in many fields of research in the natural and social sciences today, and it bears heavily on methodological problems related to economics in particular. In fact, all domains of scientific and philosophical research where it can be maintained intelligibly that an undesigned but nevertheless effective order has emerged solely through the interaction of the constituent parts of a given system and also through the interaction of this system as a whole with (...) its environment fall under what is now often preferably called the "paradigm of auto-organization". This paradigm can be traced back to Leibniz (Dobuzinkis 1989, p. 245) or even to the Spanish Jesuits of the Salamanca School of the XVIth century (Lepage 1983, p. 347), and a lot of scientific work has now been done from within its conceptual framework, for instance Varela & Maturana's theory of "autopoiesis", Heinz von Foerster's second generation cybernetic models, Ilya Prigogine's thermodynamics of open systems and dissipative structures, and chaos theory. In economics, the concept of social spontaneous order is intimately linked with Friedrich Hayek's work, and Hayek has himself insisted on the effective kinship of such approaches (Hayek 1979, p. 158). One can say that there is today in economics a full-fledged Theory of Spontaneous Order (TSO) which articulates four distinct arguments. (shrink)

A good way of characterizing what is usually called the 17th-century “revolution of modern science” is to focus on Galileo Galilei’s theory of explanation. As is well known, he set aside three of the four Aristotelian causes (material, formal and final causes) in order to base all sound scientific explanations in terms of efficient causes. In the second half of the 19th century a new scientific revolution occurred, with Darwin’s theory of evolution. As it has been stated repeatedly, Darwinism also (...) has something to do with the abandoning of teleology in science, as speciation is explained without any appeal to final causes. But in the last quarter of the 19th century a third scientific revolution occured, this time in the social sciences. Many philosophers of science fail to notice or understand this intellectual event. This third scientific revolution is usually called the “marginalist revolution.” The transformation of political economy into pure economics, and progressively, into mathematical economics had at least two distinctive features. First, this revolution broke out simultaneously but independently in three different European countries: with Carl Menger (1840- 1921) in Austria, with William Stanley Jevons (1835-1882) in England, and with Léon Walras (1834- 1910), who, in 1870, was the first to hold the Chair of Political Economy at the University of..

I investigate the consequences of Nietzsche's perspectivism for notions of truth and objectivity, and show how the metaphor of visual perspective motivates an epistemology that avoids self-referential difficulties. Perspectivism's claim that every view is only one view, applied to itself, is often supposed to preclude the perspectivist's ability to offer reasons for her epistemology. Nietzsche's arguments for perspectivism depend on “internal reasons”, which have force not only in their own perspective, but also within the standards of alternative perspectives. Internal reasons (...) allow a perspectivist argument against dogmatism without presupposing aperspectival criteria for theory choice. Nietzsche also offers “internal” conceptions of truth and objectivity which reduce them to a matter of meeting our epistemic standards. This view has pluralistic implications, which conflict with common sense, but it is nevertheless consistent and plausible. Nietzsche's position is similar to Putnam's recent internalism, and this is due to their common Kantian heritage. (shrink)
