Au cours des années 1970, le développement de la vente directe à domicile a donné lieu à la formation de cercles de sociabilité entre femmes dans le cadre des réunions Tupperware. Ces rencontres ont contribué à diffuser par capillarité nombre d’idées et pratiques féministes. Elles n’ont pas été sans incidence sur le déroulement de certaines trajectoires de femmes des classes moyennes et populaires. Le partage d’expériences de la soumission féminine, conjugale, et la confrontation aux modèles de femmes professionnalisées, les démonstratrices, (...) ont ainsi parfois ouvert à la prise de conscience du sentiment de soi et permis d’accéder à une certaine autonomie.

This paper offers a close analysis of the usage of the term circulus to refer to groups of Romans gathered together for various reasons. I identify such groupings as primarily non-elite in character and suggest that examination of their representation in our sources offers insight into popular sociability and communication at Rome. While circuli and the related figure of the circulator are often associated with what is considered to be a debased popular culture, they can also be seen as (...) part of a more general culture of popular sociability which is politically threatening to a Roman governing class that desired to monopolize and control speech and communication and in whose interest it was to channel popular political participation into the official political institutions of the city. This paper also looks at some of the strategies developed by Roman elites to maintain, in response to such unauthorized activity, their moral, intellectual, and political hegemony over the rest of the population.

With his appointment as Preacher at the Charite Friedrich Schleiermacher enters the cultural life of Berlin. For him, an important role is played by sociability, which he theorises with the anonymously published text Versuch einer Theorie des geselligen Betragens Toward a theory of sociable conduct ]. The other pole of Schleiermacher s life in Berlin is provided by science and scholarship from the Symphilosophy of his circle of early Romantic friends via participation, for example, in lectures on experimental chemistry, (...) through to theological reflection on his work at the Charite. The volume is the product of a symposium held by the Berlin-Brandenburg Academy of Sciences, and it presents a picture of this life between scholarship and sociability based on sources newly made available through the Critical Edition of Schleiermacher s Complete Works.

No doctrine of Pufendorf's is better known than that of socialitas. The reason is that Pufendorf himself declared that socialitas was the foundation of natural law. No interpreter of Pufendorf can therefore avoid dealing with it. Moreover, Pufendorf linked the issue of socialitas to the question of the state of nature, thus raising important issues with both theological and philosophical implications. Given the prominence and importance of this theme in Pufendorf's work, a close analysis of what he meant by it (...) is central to the interpretation of his work, even though this means to pose again a new number of questions already discussed in the scholarly literature. In particular, this article examines the relationship between Pufendorf and Hobbes with regard to this central theme. In fact, a traditional historiographic topos is that Pufendorf and Hobbes fundamentally disagree on the doctrine of socialitas, while the former is closer to Grotius and to the Aristotelian-classic tradition that see man as a social animal. This article takes, instead, Pufendorf to be a follower of Hobbes, and tries to explain how the more traditional view of Pufendorf as a critic of Hobbes was in some way due to Pufendorf's own attempt to distance himself from the accusations of Hobbesism (and hence of atheism and moral indifference) that the critics made against him when his work first appeared. In order to do this, Pufendorf tried to rethink his own position within the history of ethics, and put himself on the side of the Stoics, of Grotius and of Cumberland, against Epicurus and Hobbes. This retrospective ‘illusion’ has greatly influenced later scholarship, giving us a distorted image of Pufendorf's own view of socialitas. A more precise account of the latter gives a better prospective from which to look at the relationship between Pufendorf and Hobbes. ☆ The publication of this text, in this form, may require some explanation. In what it now appears the very distant June 1989, the Max-Planck-Institut für Geschichte in Göttingen organised an International Workshop on ‘Unsocial Sociability: Modern natural Law and the 18th-Century Discourse of Politics, History and Society’. The proceedings of that Workshop were never published, even though individual contributions have piecemeal appeared since then. My own contribution consisted in a short extract from a chapter from my book Samuel Pufendorf discepolo di Hobbes. Per una reinterpretazione del giusnaturalismo moderno (Bologna, 1990), which appeared in print the following year. For this reason, I considered the separate publication of that intervention as superfluous. Rather naively I underestimated the fact that the publication of my book in Italian restricted its circulation in the Anglo-American academic circles, and even if occasionally quoted, the book would not be much read. Recently, following the solicitations of many friends to present in English part of the theses developed in that book, I had decided to have my intervention at the Göttingen Workshop finally published. After all, this had amply circulated as a manuscript and been cited by many in that form. But while I was planning to revise that manuscript, I was presented with the draft translation of the second chapter of my book done by Dr. Melissa Calaresu of Cambridge University, when she was still a graduate student. It is probably better to leave aside the story of why Melissa did that translation, but I am extremely grateful to her for having allowed me to use it as the basis for this piece, which is therefore a revised version of the second chapter of my Italian book on Hobbes. I have decided to publish it in English with some hesitation, at least for two reasons. First, because with the publication in English of only part of my book I may risk to reinforce a rather simplified interpretation of my work, and consequently of Pufendorf's thought, that his main contribution lies in his doctrine of socialitas and of the state of nature. I am instead firmly convinced that the most important parts of my own work are those that are still untranslated, that is those on the nature of moral obligation and that of moral entities, beside the comparison I make in the second part of the book between the first and the second edition of De iure. Secondly, because during the intervening years I have distanced myself from a conception of the history of philosophy understood as an internal analysis of the texts, and have become more attentive to the context in which to place philosophical texts. I have therefore developed a slight impatience towards the rather nick-picking analysis of texts, which with a certain virtuosism I performed in the book. Nonetheless, since even after so many years I do not believe that the theses I developed in that book have lost their force, I am happy for this partial translation, with some essential bibliographic updating, to appear, in the hope that such theses will be finally discussed for what they are and not on the basis of second-hand reports. I am grateful to Dario Castiglione for his precious help with the final revision of the text, and to Richard Whatmore and Brian Young for their willingness to publish this translation in their Journal.

Pour Jean-Jacques Rousseau, on apprend à être citoyen dans les temps modernes en apprenant à être sociable. Si l’éducation doit renoncer à être publique, elle reste politique, tournée vers le développement des passions qui disposent à la reconnaissance.According to Rousseau, we learn to be citizens in modern times by learning to be sociable. Education can not be public one any more, as it was in the ancient cities. But it can be still a politic one : it aims to spread (...) out passions which incline to be grateful. (shrink)

Upshot: Following a brief reflection on some terminological issues, I discuss the question of the rationality of non-dualism, the two aspects of the conceptual dimension of phenomenologisation, and the potential of meditative/contemplative practices in cultivating its experiential/existential dimension. Also, I emphasise that the two-pronged project of phenomenologisation is closely associated with the establishment of second-order science, and purport to show why it might be an important addition to, and elaboration of, the overarching attempt to think and live the fundamental circularity (...) between subject and object.

Sociability and Its Enemies contributes both to contemporary studies of political theory and to discourse on postwar Germany by reconstructing the arguments concerning the nature and value of sociability as a form of interaction and interconnection particular to modern bourgeois society. Jakob Norberg argues that the writings of Hannah Arendt, Jürgen Habermas, Carl Schmitt, and the historian Reinhart Koselleck present conflicting responses to a hitherto neglected question or point of contention: whether bourgeois sociability should serve as a (...) therapeutic practice and politically relevant ideal for postwar Germany. The book sheds light on previously neglected historical and conceptual connections among political theorists, and it enriches established narratives of postwar intellectual history. (shrink)

According to Moore, his argument meets three conditions for being a proof: first, the premiss is different from the conclusion; second, he knows the premiss to be the case; and, third, the conclusion follows deductively.2 Further conditions may be required, but he evidently thinks his proof would satisfy these as well. As Moore is well aware, many philosophers will feel he has not given “...any satisfactory proof of the point in question."3 Some, he believes, will want the premiss itself proved. (...) But he has..

The quest for finding the right interpretation of Quantum Mechanics is as old as QM and still has not ended, and may never end. The question what an interpretation of QM is has hardly ever been raised explicitly, let alone answered. We raise it and answer it. Then the quest for the right interpretation can continue self-consciously, for we then know exactly what we are after. We present a list of minimal requirements that something has to meet in order to (...) qualify as an interpretation of QM. We also raise, as a side issue, the question how the discourse on the interpretation of QM relates to hermeneutics in Continental Philosophy. (shrink)

La tesis principal de este trabajo es que el principio con el que Kant comprende el origen de la cultura o de la historia humana en la tesis cuarta de I dea de una historia universal desde el punto de vista cosmopolita, la insociable sociabilidad, no implica “conceptualmente” el mal moral. Defiendo así, contra una larga tradición de lectura que sostiene lo contrario, que la cultura es producto de dos disposiciones diferentes de la especie humana que son originarias e independientes (...) de su carácter moral y, por lo tanto, también son independientes de su propensión inmoral. Esto significa, específicamente, que si hubiera unos seres racionales que fueran como nosotros, sociables e insociables, pero que no tuvieran noticia, a diferencia de nosotros, de la ley moral, esto es, que fueran moralmente inocentes, producirían, sin embargo, cultura. Como tesis secundarias muestro que se pueden establecer otras relaciones de implicación entre los conceptos de insociable sociabilidad y mal moral: por un lado, inversamente, el mal moral puede implicar “conceptualmente” la insociable sociabilidad; por otro lado, este último principio implica “contingentemente” el mal moral cuando es referido a la especie humana.

In this journal (Studia Logica), D. Rizza [2010: 176] expounded a solution of what he called “the indiscernibility problem for ante rem structuralism”, which is the problem to make sense of the presence, in structures, of objects that are indiscernible yet distinct, by only appealing to what that structure provides. We argue that Rizza’s solution is circular and expound a different solution that not only solves the problem for completely extensive structures, treated by Rizza, but for nearly (but not) all (...) mathematical structures.

Graphical AbstractYeast mitochondria frequently mutate, and some dysfunctional mitochondria out-compete wild-type versions. The retrograde response enables yeast to tolerate dysfunction, but also produces ribosomal DNA circles (ERCs). We propose that ERC accumulation increases expression of the rDNA antisense gene, TAR1, which counteracts spread of respiration-deficient mitochondria in matings with wild-type yeast.

SummaryGrotius has a rudimentary theory of sociability. Only with hindsight has a remark about appetitus societatis been promoted to the starting point of a theory that flourished in the writings of later natural jurists. In this article, I address the issue of the appearance in Grotius's natural law of sociability [as the 1715/38 English translation of John Morrice renders appetitus societatis, following Barbeyrac's sociabilité]. Writing in the just war tradition, Grotius is first of all interested in finding out (...) the conditions for peace, and although injustice is a condition of war, it is not per se true that injustice is a perversion of society. Apparently, not all societies are perfect and the violence of war and the legal actions of peace are both instruments for achieving a greater modicum of justice in this world. Yet appetitus et custodia societatis is called the foundation of justice. Grotius achieved this context for sociability in phases, through a series of writings from c. 1600 until De iure belli ac pacis of 1625, and its revision of 1631. In this development the notion of fides plays an intriguing role, through which we can obtain a better understanding of the meaning of appetitus societatis in the later work. The present article is a sequel to a previous publication, on fides in De iure praedae. Analysing the genesis of appetitus societatis in De iure belli ac pacis, I argue that Grotius was changing his strategy over the years, without however arriving at a definitive solution to the question of what commits men to the pursuit of justice.

Christian Jakob Kraus (1753–1807), political economist and Professor of Practical Philosophy at the University of Königsberg, has long been neglected by historians, dismissed as a translator, a teacher, and a derivative disciple of Adam Smith. This article posits sociability as a useful category for understanding Kraus’s life, thought, and legacy. It aims to thereby reposition him as a meaningful figure in the late German Enlightenment. First, Kraus is presented as a natural Einsiedler who, surrounded by the commercially vibrant Königsberg, (...) comes to champion a methodology foregrounding praxis, lived experience, and the application of ideas for communal benefit. This ‘sociable’ approach to knowledge is contextualised within broader critiques of scholarly esotericism across Germany. Second, his work is treated as a case study elucidating the interdependence of individualism and sociability in the wider European Enlightenment. I argue that Kraus expressed a ‘sociable individualism,’ drawing upon Smith and Immanuel Kant, which harmonised autonomy and community. (shrink)

Classically, an osculating circle at a point of a planar curve is introduced technically, often with formula giving its radius and the coordinates of its center.

SummaryThis article studies the impact of the debate about human sociability on the crisis of natural law in the later eighteenth century examining the Untersuchungen über den Stand der Natur of 1780 by the Göttingen scholar Michael Hissmann. It makes the case that this crisis ensued from Rousseau's Discours sur l‘inégalité and a revival of neo-Epicurean trends in moral philosophy more generally. The sociability debate revolved around the question to what extent society was natural or artificial to man. (...) This had important implications for the problem of whether distinctions between right and wrong or just and unjust were natural and inborn, or had developed at a much later stage of mankind's history, reflecting merely the respective needs and utility of different societies and cultures. Hissmann's essay summarises this European debate concisely. His point of departure is Rousseauian premises, yet his political conclusions turn Rousseau upside down. Here, Hissmann's essay opens up several questions regarding the allegedly radical political character of one-substance theories in philosophy. (shrink)

The robotics industry is growing rapidly, and to a large extent the development of this market sector is due to the area of social robotics – the production of robots that are designed to enter the space of human social interaction, both physically and semantically. Since social robots present a new type of social agent, they have been aptly classified as a disruptive technology, i.e. the sort of technology which affects the core of our current social practices and might lead (...) to profound cultural and social change. -/- Due to its disruptive and innovative potential, social robotics raises not only questions about utility, ethics, and legal aspects, but calls for “robo-philosophy” – the comprehensive philosophical reflection from the perspectives of all philosophical disciplines. This book presents the proceedings of the first conference in this new area, “Robo-Philosophy 2014 – Sociable Robots and the Future of Social Relations", held in Aarhus, Denmark, in August 2014. The short papers and abstracts collected here address questions of social robotics from the perspectives of philosophy of mind, social ontology, ethics, meta-ethics, political philosophy, aesthetics, intercultural philosophy, and metaphilosophy. -/- Social robotics is still in its early stages, but it is precisely now that we need to reflect its possible cultural repercussions. This book is accessible to a wide readership and will be of interest to everyone involved in the development and use of social robotics applications, from social roboticists to policy makers.

This article argues that the notions developed by post-Kleinian object relations psychoanalysis are continuous with a certain British political tradition. British object relations authors think that the healthy personality necessitates a social-democratic political environment. Their ideas follow both historically and logically upon a set of notions about human development that resemble those held by advanced liberals and social democrats since the nineteenth century. Social democracy and advanced liberalism perceive sociability and community as goods that complement traditional liberals? respect for (...) autonomy and individual difference. Much of this outlook evolved from an earlier preoccupation with the exclusive discretion of already-existing individuals over portions of their lives. This concern has been gradually transformed into an interest in enhancing the conditions under which the autonomous personality may form. (shrink)

SummaryIn his early years Herder is known to have been a follower of Rousseau. This article argues that there was indeed a substantial overlap between Herder's and Rousseau's ideas in Herder's early writings, particularly in terms of their joint critique of abstract philosophy and their understanding of the sentimental foundations of morality, as well as their commitment to the ideals of human moral independence and political freedom. Yet Herder's admiration for Rousseau's moral philosophy did not lead him to adopt Rousseau's (...) critique of sociability even in this early period, and there was in fact a deep divergence between their political views. Herder attempted to combine a Rousseauian cultural critique, ‘human’ moral philosophy and philosophy of education with ideas inspired by Thomas Abbt's theory of monarchical patriotism. In contrast to Rousseau, and following Abbt, Herder posited the existence of natural patriotic feelings and underlined their importance in guaranteeing good government and political freedom. Thus, Herder could have a relatively optimistic view of the role of ‘human philosophy’ in regenerating patriotism in a modern setting. Herder embraced Abbt's emphasis on the positive aspects of modern monarchies and ‘modern liberty’ when compared to ancient republics, highlighting the compatibility of Christianity, international commerce and religious tolerance, and the general possibility of developing one's natural inclinations in modern monarchies.

I approach the philosophical analyses of the phenomenon of trust vis-à-vis online communication beginning with an overview from within the framework of computer-mediated communication (CMC) of concerns and paradigmatic failures of trust in the history of online communication. I turn to the more directly philosophical analyses of trust online by first offering an introductory taxonomy of diverse accounts of trust that have emerged over the past decade or so. In the face of important objections to the possibility of establishing and (...) fostering trust in online environments—objections that emerge especially from the perspective of virtue ethics and phenomenological approaches to how we know and navigate the world as _embodied_ beings—I then take up three major arguments in recent work in favor of the possibilities of trust online, followed by three _vicious circles_ that run counter to more optimistic views. I close with a summary of some additional reasons for optimism regarding trust online, followed by a final question that emerges out of recent CMC research on social networking sites that poses, I argue, fundamental challenges indeed to how we understand and may foster and experience trust online.

In the seventeenth and eighteenth centuries, the concept of sociability was used mainly to refer to the putative range of primary human qualities or capabilities that preceded—or existed independently of—the formation of political societies. This article is an examination of the impact of Rousseau's thought on this then standard usage. Its initial focus is on Rousseau's concept of perfectibility and its bearing on the thought of Marie-Jean-Antoine-Nicolas de Caritat, marquis de Condorcet, and Friedrich Schlegel. Its broader aim is to (...) show how their respective responses to Rousseau were part of a more deep-seated transformation of the concept of sociability itself. (shrink)

This book is about questions that one would hesitate to ask in certain groups, because the questioning itself would mark him or her as an outsider, or a liberal, or a conservative, or a reactionary interested in resurrecting issues which have been satisfactorily settled.

In this book the interlocutors, who disagree about almost (...) everything, nevertheless search for areas of agreement as they continue in this Socratic tradition. (shrink)

The idea of sociability - a person’s disposition and ability to communicate and live in the community - goes through the whole history of philosophy. Due to the peculiarity of translations, this term and the whole tradition related to it have been lost to the Russian reader. The article discusses some tendencies in comprehending the idea of sociability in early modern moral philosophy. The key to this consideration is F. Hutcheson’s essay On the Natural Sociability of Mankind, (...) the title of which contains the very term “sociability” and which presents the main essential points in a discussion of the issue in the first third of the 18 th century. One can distinguish two main approaches to the problem. According to one of them, sociability determined by various human natural needs is the basis of social relations, and a person becomes a moral agent as a social being (H. Grotius, T. Hobbes, S. Pufen-dorf, B. Mandeville). According to another approach, sociability is a manifestation of a person’s natural tendency to care for the good of others, and its consistent implementation leads to the formation of community and supports its stability (Cambridge Platonists, Shaftesbury, Hutcheson, J. Butler, D. Hume, A. Smith). Representatives of both approaches recognized contradiction in manifestations of sociability or in its nature. I. Kant theoretically overcame the confrontation between these approaches and conceptualized the contradiction and associated it with the human nature. According to Kant, the “unsociable sociability” is given in the fact that a person has a tendency to sociability but also a tendency to self-assertion at the expense of others. However, despite the presence of asocial features (evil principle), Kant considered the person’s inherent sociability (good principle) as a prerequisite for culture and as one of the most important conditions of possibility of morality.

This is a review of Vicious Circles: On the Mathematics of Non-Wellfounded Phenomena, written by Jon Barwise and Lawrence Moss and published by CSLI Publications in 1996.

The paper is devoted to the presentation and analysis of the philosophical views concerning logic and mathematics of the leading members of Cracow Circle, i.e., of Jan Salamucha, Jan Franciszek Drewnowski and Józef Maria Bocheński. Their views on the problem of possible applicability of logical tools in metaphysical and theological researches is also discussed.

We offer a novel interpretation of the argumentative role that Meditation IV plays within the whole of the Meditations.

This paper examines the reactions to the British labour unrest of 1910?1914 among the writers associated with two Edwardian periodicals, the Catholic Distributivist New Witness, and the advanced socialist New Age. Both papers were thrown into sympathy with the strikes whether through libertarianism, hatred of capitalism or the glorification of violence and struggle. This prompted theoretical discussions on the future organisation of labour in which liberty and consensus were precariously balanced, and mediated through elitism. By examining the contested and ambiguous (...) origins of guild socialism, the paper draws tentative conclusions about its troubled legacy. (shrink)

SummaryThis article reconstructs a significant historical alternative to the theories of ‘cosmopolitan’ or ‘liberal’ patriotism often associated with the Scottish Enlightenment. Instead of focusing on the work of Andrew Fletcher, Francis Hutcheson, David Hume or Adam Smith, this study concentrates on the theories of sociability, patriotism and international rivalry elaborated by Adam Ferguson and Henry Home, Lord Kames. Centrally, the article reconstructs both thinkers' shared perspective on what I have called ‘unsociable’ or ‘agonistic’ patriotism, an eighteenth-century idiom which saw (...) international rivalship, antagonism, and even war as crucial in generating political cohesion and sustaining moral virtue. Placing their thinking in the context of wider eighteenth-century debates about sociability and state formation, the article's broader purpose is to highlight the centrality of controversies about human sociability to eighteenth-century debates about the nature of international relations.

This article, through a case study of the Royal Dublin Society (RDS), traces the reception, experimentation with, and uses of radium in early twentieth-century Ireland. Throughout the nineteenth century there was increasing state intervention in the provision of scientific and technical education in Ireland. This culminated in the loss of the RDS's traditional role in this area. The article demonstrates that the RDS was forced to re-envisage its role as a scientific institution by actively seeking to support experimental research. Using (...) radium as a case study, the article argues for the success of this tactic. It demonstrates that radium played a central role within the RDS as a nexus for the maintenance of an experimental and philanthropic culture that permeated much of the society's scientific output in this period. In doing this it highlights the importance of sociability in the promotion of science in Ireland in the early twentieth century. In addition, it explores the role of the RDS as an arbiter of scientific authority. (shrink)

Proof-theory has traditionally been developed based on linguistic (symbolic) representations of logical proofs. Recently, however, logical reasoning based on diagrammatic or graphical representations has been investigated by logicians. Euler diagrams were introduced in the eighteenth century. But it is quite recent (more precisely, in the 1990s) that logicians started to study them from a formal logical viewpoint. We propose a novel approach to the formalization of Euler diagrammatic reasoning, in which diagrams are defined not in terms of regions as in (...) the standard approach, but in terms of topological relations between diagrammatic objects. We formalize the unification rule, which plays a central role in Euler diagrammatic reasoning, in a style of natural deduction. We prove the soundness and completeness theorems with respect to a formal set-theoretical semantics. We also investigate structure of diagrammatic proofs and prove a normal form theorem. (shrink)

There is a tension between our need for associative control and our need for social connections. This tension creates ethical dilemmas that we can call each-we dilemmas of sociability. To resolve these dilemmas, we must prioritize either negative moral rights to dissociate or positive moral rights to social inclusion. This article shows that we must prioritize positive social rights. This has implications both for personal morality and for political theory. As persons, we must attend to each other's basic social (...) needs. As a society, we must adopt a sufficientarian approach to the regulation of social resources. (shrink)
