How many words—and which ones—are sufficient to define all other words? When dictionaries are analyzed as directed graphs with links from defining words to defined words, they reveal a latent structure. Recursively removing all words that are reachable by definition but that do not define any further words reduces the dictionary to a Kernel of about 10% of its size. This is still not the smallest number of words that can define all the rest. About 75% of the Kernel turns (...) out to be its Core, a “Strongly Connected Subset” of words with a definitional path to and from any pair of its words and no word's definition depending on a word outside the set. But the Core cannot define all the rest of the dictionary. The 25% of the Kernel surrounding the Core consists of small strongly connected subsets of words: the Satellites. The size of the smallest set of words that can define all the rest—the graph's “minimum feedback vertex set” or MinSet—is about 1% of the dictionary, about 15% of the Kernel, and part-Core/part-Satellite. But every dictionary has a huge number of MinSets. The Core words are learned earlier, more frequent, and less concrete than the Satellites, which are in turn learned earlier, more frequent, but more concrete than the rest of the Dictionary. In principle, only one MinSet's words would need to be grounded through the sensorimotor capacity to recognize and categorize their referents. In a dual-code sensorimotor/symbolic model of the mental lexicon, the symbolic code could do all the rest through recombinatory definition. (shrink)

The open Nambu string is revisited in the spirit of an early approach by Rohrlich. Strictly timelike motions only are considered. The proper-time of the center-of-mass is taken as preferred parameter. We propose a canonical formalism in terms of a countable infinity of variables, among them the modes. But the barycentric coordinates have noncommuting components, which makes possible a consistent quantization (in any dimension, four in particular) within the framework of a transverse space of states. If a maximal number of (...) modes is further fixed, a transverse Hilbert space emerges, where spacetime displacements preserve the (positive-definite) scalar product. (shrink)

This is a tentative theory of quantum measurement performed on particles with unspecified mass. For such a particle, the center of the wave packet undergoes a classical motion which is a precious guide to our approach. The framework is manifestly covariant and a priori nonlocal. It allows for describing an irreversible process which lasts during a nonvanishing lapse of time. The possibility to measure a dynamical variable in an arbitrary slate is discussed. Our picture is most satisfactory if we focus (...) on free particles and constants of the motion. Two-particle systems and measurement of individual observables in a correlated slate are considered. (shrink)

Directly interacting particles are considered in the multitime formalism of predictive relativistic mechanics. When the equations of motion leave a phase-space volume invariant, it turns out that the phase average of any first integral, covariantly defined as a flux across a 7n-dimensional surface, is conserved. The Hamiltonian case is discussed, a class of simple models is exhibited, and a tentative definition of equilibrium is proposed.

La notion de « cause secrète », à laquelle les classiques ont largement eu recours, est liée à une pratique de la science et à une conception de ses méthodes telles que la « loi » se trouve au coeur du dispositif. Si certains phénomènes paraissent ne pas être régis par la loi, il faut alors se mettre à amender la loi par de « petites équations ». Si le calcul des probabilités entre en scène, c'est pour déceler précisément la (...) présence de causes qui, d'abord secrètes, le seront moins par la suite, et seront, de toute façon, conformes aux lois.

In recent decades, the development of sciences and technologies had a significant impact in society. This impact has been object of analysis from several standpoints, i.e., scientific, communication, historical and anthropological. Consequently, serious changes were required by the society. One of these has been the emerging relationship science in society and its foundations of applied sciences. A related foundational challenging is the educational process, which was and still is an unlimited challenge for teachers and professors: i.e., levels of understanding, curricula, (...) activing critical engagement, transfer knowledge—and—skills, management, classroom and subsequently pre-service teachers need special teacher education. Taking into account Joule’s bicentenary commemoration in physics and Nature of Science teaching this paper introduces to a level of inquiring within historical and NoS approaches in the pre-service teachers, typically science, technology, engineering and mathematics. In particular, history and historiography of Joule’s physics are dealt with. (shrink)

“No one can serve two masters.” This Bible quotation highlights an irreducible contradiction, which echoes numerous organizational settings. This article considers the under-explored ethical implications of paradoxical injunctions created by such a contradiction at the managerial level. Contradictory organizational constraints turn into paradoxant systems , where the organization structurally settles paradoxical injunctions which challenge managerial ethics in practice. We then ask what managerial responsibility means in such contexts and find that managers have then to reshape their practice as a situated (...) construction through constant mediation between different “masters” and bricolage (i.e., tinkering with concepts). An ethnographic case study of an anti-money laundering service in an investment bank illuminates this phenomenon from a practice perspective. The possibility to enact an actual ethical practice within the contradictory organization relies on a new role of the manager. This implies drawing on an approach of responsible management as an enactment of ethics in practice which is situated within the framework of a new conception of both the organization, as a structurally “paradoxant system,” and the manager as a mediator in charge of enacting coherence.

This scoping review addresses the issues of responsible conduct of research (RCR) that can arise in the practice of research-creation (RC), an emergent, interdisciplinary, and heterogeneous field at the interface of academic research and creative activities. Little is yet known about the nature and scope of RCR issues in RC, so our study examined three questions: (1) What are the specific issues in RC in relation to RCR? (2) How does the specificity of RC influence the understanding and practice of (...) RCR? (3) What recommendations could help address the issues highlighted in the literature To answer these questions, we conducted a scoping review of the academic literature (n = 181 texts) dealing with RCR in RC. We found that researcher-creators faced some very different RCR challenges in comparison with their colleagues in the rest of academia. Addressing these issues is important for both the RCR and RC communities in order to ensure that the rapid development of this field occurs in line with the norms of RCR which, nonetheless, should be adapted to respect the particularities of RC and allow its contributions to the academic world.

James Prescott Joule’s (1818–1889) bicentenary took place in 2018 and commemorated by the IDTC with a Symposium—‘James Joule’s Bicentenary: Scientific and Pedagogical Issues Concerning Energy Conservation’—at the European Society for the History of Science (ESHS & BSHS), 14th–17th September, 2018, in London. This symposium had three main objectives: It aimed specifically to celebrate James Joule’s achievements considering the most recent historiographical works with a particular focus on the principle of conservation of energy; It served the purpose of discussing the scientific (...) and pedagogical issues related to heat, energy and work and how they are presented in textbooks and worked out in classrooms; It also provided discussions on the present situation of teaching and learning science through the use of History of Science, both in K-12 and college level with an emphasis on energy and related concepts. In the following, the Introduction of this Special Issue on Joule is presented. (shrink)

New concepts may prove necessary to profit from the avalanche of sequence data on the genome, transcriptome, proteome and interactome and to relate this information to cell physiology. Here, we focus on the concept of large activity-based structures, or hyperstructures, in which a variety of types of molecules are brought together to perform a function. We review the evidence for the existence of hyperstructures responsible for the initiation of DNA replication, the sequestration of newly replicated origins of replication, cell division (...) and for metabolism. The processes responsible for hyperstructure formation include changes in enzyme affinities due to metabolite-induction, lipid-protein affinities, elevated local concentrations of proteins and their binding sites on DNA and RNA, and transertion. Experimental techniques exist that can be used to study hyperstructures and we review some of the ones less familiar to biologists. Finally, we speculate on how a variety of in silico approaches involving cellular automata and multi-agent systems could be combined to develop new concepts in the form of an Integrated cell (I-cell) which would undergo selection for growth and survival in a world of artificial microbiology.

Capricci are nonsense drawings that delineate an elusive but inevitable sense behind or, better, within the palpable nonsense of the elementary proposition of a drawing; they are capers on a tightrope stretched between the poles of pathos and the ridiculous. We shall succeed in not falling only if we step forward boldly and know not only what we are doing but also what we are up against in the making of a picture as well as in living in the world. (...) For the world, in its yawning impudence of death and the dance of blind eagerness, ambition, and noisy speechlessness, makes us look to art not, or not necessarily, to escape from the world but rather to learn how to take its measure. . . . There is a painting ["St. Vincent Ferrer Preaching"] joined to the Passion cycle in S. Polo which demonstrates as well as any paradox ever will how Giandomenico joined piety and irony in his religious art without curtailing the glory of either. He arrives, as it were, at a God-fearing irony. We see St. Vincent Ferrer preaching. He speaks so eloquently, so convincingly in praise of the divine truth, that light shines forth from him and angel's wings grow on his shoulders. Fascinated by the miracle but even more so by the saint's words, his audience sits spellbound at his feet; in the foreground, however, sits a youth, a fop perhaps, gorgeously dressed, with a singular smile on his face, his hand musingly poised to his cheek, who looks at us quizzically. He is the link between us and the miracle. "Can you believe it?" says the smile, and perhaps "I did not—and yes—how can you now not believe it, you need but look - as I did - for there it is!" It is, I think, the face of one who knows about the truth of the absurd and its inner logic. Credo quia absurdum: if it were not so, we could prove the existence of God by feeding data into a computer, and there would be many believers, whose faith, in turn, deserved but little credit. Needless to say, perhaps, the face that so speaks to us in laughter joined to wonder is a self-portrait.1 · 1. In S. Polo the painting of St. Vincent Ferrer Preaching hangs opposite a matching picture of The Finding of the True Cross. There is a beautiful young woman on the right who looks at us beseechingly and with her right hand points at the cross. Giovanni Domenico Tiepolo who looks out of St. Vincent Ferrer Preaching cannot help but see this lady and be affected by her earnest gesture. For a reproduction of the painting, see Maruz, G. D.

continent. 1.2 (2011): 129-135. Introduction Vincent W.J. van Gerven Oei Successions of words are so agreeable. It is about this. —Gertrude Stein Nachoem Wijnberg (1961) is a Dutch poet and novelist. He also a professor of cultural entrepreneurship and management at the Business School of the University of Amsterdam. Since 1989, he has published thirteen volumes of poetry and four novels, which, in my opinion mark a high point in Dutch contemporary literature. His novels even more than his poetry (...) are criticized for being inaccessible, which I generally take to be a compliment. It would be like saying that Fernando Pessoa is inaccessible, which he is not. Neither is Wijnberg. When we think of the combination economist-poet we are immediately reminded of the American poet Wallace Stevens, who, as the story goes, had two stacks of paper on his desk, one for contracts, one for poems. We also know that Stevens wrote on the economy and that questions of economy and insurance surface at multiple points in his poems. The following text is a very preliminary attempt to point at the intersections between poems, novels, business, and poetry in Wijnberg’s work. On the back cover of his novel De opvolging ( The Succession , 2005), Wijnberg states the following: “[This is] a novel for whomever is interested in the workings of a company as much as in the workings of a poem.” Wijnberg thus claims that the way in which a company “works” may be similar to the way in which a poem “works.” The question is the obvious one, what does this similarity consist in? De opvolging tells the story of company in which bosses and company doctors, secretaries, children, clowns, and beggars have tons of meetings, recite poems, perform plays, tell jokes, and succeed each other, climbing up and down in the company’s hierarchy. De opvolging is a novel in which the career of people follows the career of words. It resonates with Gertrude Stein's sentences, "Grammar. What is it. Who was it" (1975, 50). The words in Wijnberg's poems are like he characters in his novel. And if we keep in mind this allegorical reading of De opvolging , which is obviously only one of the possible readings, we may be able to understand some aspects of Wijnberg’s poetry. A repetition is already a pun. Look, that word is trying it again, as if it is afraid that by not doing it it would give up the hope that it will ever be able to do something. A pun is the opposite of the first word coming to the mind of someone who shouts it when he suddenly discovers something. (104) The repetition, the succession of the same word, is already a pun, a joke. The succession of the father by the son after the revolution is a joke. "Look he's trying it again!" The essence of a joke is a repetition. Archimedes’ “Eureka!” is its opposite. Poems can easily become jokes, depending on the way the words follow and repeat each other. In De opvolging , the careers of the bosses, good and bad secretaries, and company doctors easily become jokes, as they are “afraid that by not doing it [they] would give up the hope that [they] will ever be able to do something.” Not only the repetition, but also the distance and difference between the words in a poem, their cause and effect relations can be read as company relations. This becomes clear when we, for example, read the first lines of the poem “Cause, sign” from Het leven van ( The Life Of , 2009). A sign lets know what is going to happen, a cause lets it happen. If the sign also lets happen there is no reason to isolate it, because then I would isolate some- thing only because it’s different for me. If I didn’t have to write this myself, but would have secretaries to whom I could dictate it, I would be able to say more about it. (49) Upon reading the first two lines we can already conclude that any word may be cause or sign or both. If a sign is also a cause there is no reason to discriminate it, yet to the poet they are still different. This difference only becomes expressible the moment he would have a secretary. Just like in De opvolging , the secretary introduces a distance; not in a company but in a poem. Hence the difference between “good” and “bad” secretaries in a company, where the good secretary of one boss may be the bad secretary of another one. The more we can say about the bosses of the company, or signifiers of the poem, the greater the distance we introduce between them and us. We should take serious the relation between Wijnberg’s novels and poems. Although they operate on different scales, they explain and converse with each other. Another example may be the novel Politiek en liefde ( Politics and Love , 2002), which deals with the relation, precisely, between politics and love. In the novel, Nicolai, a lieutenant in the Dutch army, is sent to Africa on a military mission. Upon leaving a receives a letter from his father. Dear son, Don’t do anything stupid before your father has advised you to do so. Your mother asked me to write a wise letter. I have been looking for wisdom for half a day and haven’t found much. If you borrow a small amount from a bank you become the bank’s slave, but if you borrow a couple of millions and spend them as quickly as possible the bank becomes your slave. What I want to say is that you have to return from Africa in good health, and before you know it the world will be your slave [....] Signed with a kiss from your father. (88) The line, “If you borrow a small amount from a bank you become the bank’s slave, but if you borrow a couple of millions and spend them as quickly as possible the bank becomes your slave,” returns as the title of poem in Het leven van: “If I borrow enough money the bank becomes my slave” (12-3), which elaborates this theme. So both in the way that these poems are structured and in their subject matter, they refer to the structures of our economy, to the ever-continuing line of CEOs succeeding each other like words, to the distance between them introduced by bureaucracy, and giving and receiving as economical and poetical acts. Poem and economy map onto each other, as in another episode from De opvolging : Edward reads two of the beggar’s poems about presents. Of a holiday nothing remains, except for memories, and if some of them are bad I’d rather forget them all; if I get a present I’d rather get something that’s useful to me for a long time. If I may choose, I choose what I can use longest, long enough to partially forget that this was the present, because it feels bad when nothing is left of it. […] Giving away becomes destruction in the stock destruction economy [ voorraadvernie -tigings-economie ], that is a gift economy [ geschenkeneconomie ], encountering for the first time an economy in which there’s selling and buying on markets. Instead of destroying supplies someone can also quickly say that they aren’t worth anything anymore; if someone wants to take them I’d gladly give him something extra. In a stock destruction economy he is someone who each day wants to work more hours than his colleagues. If around a company there is a gift economy in which someone’s rank is determined and made visible by the gifts someone can give someone else, a company will be more often character- ized by an invisible or unclear system of ranks. (152) Two poems about gifts present two different economical models, described by Wijnberg with the terms “stock destruction economy” and “gift economy.” Here we immediately recall the opposition introduced by George Bataille’s work on the concept of expenditure in The Accursed Share , where a “general economy” would surpass the stock destruction economy based on scarcity (capitalism) and become a gift economy (potlatch) and an egalitarian (communist) society. These claims are made both on the level of the poems and in their discursive explanation. They follow each other and on each other. I would like to finish this introduction to Wijnberg’s writing with a translation from his novel De joden ( The Jews , 1999), which develops the story of Hitler abdicating as chancellor of the Third Reich, appointing philosopher Martin Heidegger as his successor. In a conversation with two Russian actor-spies, sent by Stalin to figure out the situation, philosopher Walter Benjamin describes the abdication scene. Maimon: You were there when Hitler resigned? Benjamin: In the room we’re right now. The desk and the chairs are new. After his resignation Hitler would like to take his furniture to his new house. Martin naturally agrees. It is a sunny day. Martin is very nervous and complains about the heat. Martin is wearing his best dark blue suit, not his professor’s robe. Hitler is wearing his uniform. We enter the room and Hitler gets up and embraces Martin. Martin is not very good at embracing. Hitler shakes his hand. Hitler’s cap is on the desk. The cap has a metal lining. Hitler has strong neck muscles. Hitler says: A man is unclean. He takes a bath. Does he make the bath water unclean? I say: a man is unclean. He steps into a river. A little further a man steps into the river; does he become unclean? Hitler nods. I say: a man is standing in music. Another man hears the music but also sees the first man moving on the beat of the music in a way that he is certain that the music would excite different feelings in him if he wouldn’t to see the first man. Hitler says: a man is clean, listens to music, is suddenly touched and he doesn’t know by what. The conversation ends in the way you know it ends. Hitler picks up his cap from the desk and puts it on Martin’s head. (73-4) Aware of the never ending debate on the question of Heidegger’s involvement in the Nazi regime, Wijnberg has the audacity to present the arguments of complicity in the religious terminology of cleanliness and uncleanliness, while at the same time recalling overtones of Hitler’s supposed love for Wagner, suggesting a relation between Benjamin and Hitler, and so on. The space of this introduction is to small to treat a novel like De joden , a reading of which together with passages from Philippe Lacoue-Labarthe's Heidegger, Art, and Politics: The Fiction of the Political , Jacques Derrida's Of Spirit , Christopher Fynsk's Heidegger: Thought and Historicity , and Avital Ronell's The Telephone Book would be extremely elucidating and potentially open new avenues in thinking Heidegger's emphasis on poetry after the fall of the Nazi empire. But at this point we will have to curb our curiosity and follow the poet himself. The themes of the relation between business and poetry, but also Chinese landscape painting, love, Indian and Japanese poetry, and Western philosophy are analyzed and assimilated in Wijnberg’s work without ever losing the clarity of expression. It may be that, according to Alain Badiou, the “Age of the Poets” is over, but its end (Paul Celan) has exactly brought a new balance between philosophy and poetry, and it is this playful, but nonetheless serious balance that makes one hope that one day Wijnberg’s complete oeuvre might become available to readers across the planet. Tiranë, Albania February 15, 2011 English translations (all of them translated by David Colmer, who is preparing an English collection of Wijnberg’s poems entitled Advanced Payment ): Poetry International Words Without Borders Green Integer Review from Het leven van ( The Life of ) THE LIFE OF KANT, OF HEGEL As if every day he takes a decision that is as good as when he’d been able to think about it all his life. The life of Kant, of Hegel, the days of the life of, select three or four of them. Tell what he has discovered during those days as if he were the last one who knew so little. Give me something that I can cancel against then I can prepare myself for it. The reward is that I may continue with what I’m doing, it doesn’t matter how long it takes. This has nothing to do with everything remaining the same if I say that I no longer want anything else. I wouldn’t be able to say in which one and the other occur in a way that I if I knew something to cancel that one against it wouldn’t be possible now. The stars above my head and being able to say what belongs to what if I’ve let them in. FOLLOWING MY HEART WITHOUT BREAKING THE RULES Observing the rules without observing the rules by going where the rules no longer apply. I could also observe the rules there by applying them to what at great distance may resemble what the rules are about. But why would I do that, not to confuse someone who is seeing me from a great distance? Behind this morning the morning prepares itself when the rules are everything I have. IF I BORROW ENOUGH MONEY THE BANK BECOMES MY SLAVE A bank lends me money, if I don’t pay it back they tell my boss that he has to pay them my salary. But they have to leave me enough to eat and sleep and an umbrella when it’s raining. They can also empty my house, the furniture isn’t worth a lot, but every little helps. Each morning I leave for work, if I don’t start early they’ll soon get someone else, no bank will lend me money when the sun is shining. My boss has given me a cat to raise as a dog. Of course I know that it won’t work out, but I’ve asked for a week—maybe the cat gets lucky, maybe I get lucky. My hands around a cup of coffee, before I leave for work, warm-empty, cold-empty, as if hidden in the mist over a lawn. What I make when there’s no work left for me, I’m ashamed to say how little it is. Once I’m outside I check it, if they watch out of the window they can see me doing it. Suppose it is so much that I’d stay counting for hours, it’s getting dark and I’m still there. They stay watching for a while once they’ve finished their work, but have to go home, I get that, sure, I could also go home and continue counting there. If it’s too little running back immediately won’t help, because nobody’s there anymore, and if I come back tomorrow I may have spent what’s missing tonight. Going somewhere where it’s warm enough to walk around without clothes during daytime, it helps me to know that something’s more there than here. For someone like me there’s work anywhere, it shouldn’t take a week to find work for me there. Three times work and a home close to work, I may choose one and try for a week whether I want to stay there. If at the end of the week I don’t want to stay I’m back on the next day, then it was a week’s holiday. RULES If that’s against a rule, it’s yet another one that I cannot observe, or only so briefly that I cannot re- member it later. Anyways the rules are only there to help me remember what I need in order to do better what I do. In that respect there’s no difference between the rules that I find in a book and the rules that I think of early in the morning. I know that because I’ve made a rule just now nothing has yet to observe it. CAUSE, SIGN A sign lets know what is going to happen, a cause lets it happen. If the sign also lets happen there is no reason to isolate it, because then I would isolate something only because it’s different for me. If I didn’t have to write this down myself, but would have secretaries to whom I could dictate it, I could to say more about it. If something is taken away from me I consider how it would be if the opposite had been taken from me. That is what causes or signifies what is farthest away from what is caused or signified by what has been taken away from me. note: For the translations of “The life of Kant, of Hegel” and “If I borrow enough money the bank becomes my slave” I was able to consult David Colmer’s wonderful translations.

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 119 alienated, as a result of their doctrines, a large segment of the Islamic community. As a matter of fact the mu'tazilites were branded as infidels by the community. The remainder of the book, i.e. chapters 4, 5, and 6, are respectively devoted to the expected deliverer, the emphasis on struggle (jihad) and the friends of god. The essays concerning the expected deliverer and the friends of (...) god are philosophically uninteresting, except I should add for some of the editor's commentaries. However the essays on struggle are illuminating, for they attempt to clear some of the standard misconceptions about the use of the term "jih~d," which is usually translated into English as "holy war." No doubt the early Muslims did engage in holy wars. The underlying justification for waging such a war was primarily for self-defense and secondarily for strengthening Islam. However the modern interpretation of fihad is in striking contrast to the traditional one. A modern writer expresses it as: It (jih~d) denotes a state of mind in which after undergoing sufferings, a man is forced to resort in self-defense to measures not necessarily warlike. In daily life we find people saying that they wish to carry on a ]ihad against drinking and smoking or against foreign goods. But this does not mean that they intend making a war on anybody.... It [i.e. fih~d] is an institution which enjoins on every Muslim to sacrifice his all for the protection of the weak and oppressed. He is duty bound to see that oppression and injustice, in whatever form, are stopped. (p. 300) As I indicated earlier this book is unlike many others dealing with Islamic civilization. What is needed now is for Western philosophers to start seriously entertaining some of the philosophical themes in the intellectual development of Islam. This is indeed a neglected area; hopefully then Themes o[ Islamic Civilization could be a starting point for some of us in philosophy. ROBERT ELIAS ABU SHANAB The Florida Stale University, Tallahassee Inventaire de la correspondance d'Andrd Rivet (1595-1650). By Paul Dibon. (La Haye: Nijhoff, 1971. xxiii and 406 pp., FI. 90) The French protestant A. Rivet (1572-1651), a confidant of La Tr6moille and of Duplessis-Mornay, was appointed professor of theology at Leyden University in 1620, immediately after the Dordrecht Synod. In 1632 he was appointed tutor to the Prince of Orange, the future William II, and was an advisor to the Stathouder FredericHenry. He maintained a lively correspondence with more than 450 personalities in the learned world, without regard to religion or nationality. Notable among his correspondents are Louis Cappel, Valentin Conrart, Jean Daille, Samuel Desmarets, Charles Drelincourt, Paul Ferry, Pierre Gouhier, J. F. Gronovius, C. Huygens, J.-M. de Langle, Antoine L~ger, Mersenne, Andr~ Pineau, Abraham Rambour, Guillaume Rivet (his brother), Claude de Saumaise, Philippe Vincent, G.-J. Vossius, David Willem. The correspondence, starting in 1595, includes about 4,350 letters, of which only 480 have hitherto been published. Topics of the correspondence are recently published books, diplomatic, political, and military events, ideological disputes, etc. Through his connections, Rivet received a considerable amount of qualified and, frequently confidential information, and this is an invaluable source for the study of the intellectual and political history of his time. Rivet published about sixty books, sermons, and pamphlets, in Latin and in French, mostly on theological subjects. The most important were collected in his 120 HISTORY OF PHILOSOPHY Opera theologica quae latine edidit, 3 vols. (Roterodami, 1651-1660). His religious polemics with Amyrault and Grofius were famous. Paul Dibon, professor at the Ecole Pratique des Hautes Etudes, is the most prominent contemporary historian of seventeenth-century Dutch philosophy and intellectual life; he is perfectly aware of the fact that genuine history can only be founded on solid erudition, and this inventory is a first-class contribution to it. Only those who ignore the difficulties of this kind of research will underestimate the enormous effort it involves--an effort which is, much more than a pedantic and mechanical listing of data, a kind of venatio, requiring a continuous alertness, a surprising amount of imagination and intelligence, a...

Maldiney est né en 1912, année où le cinéma est quant à lui devenu un art, pour la première fois de type industriel. Ce philosophe en a donc été, toute sa vie durant, le contemporain. Et pourtant il ne s’y est manifestement jamais intéressé. Or cela est d’autant plus intrigant que, si la peinture a certes toujours été pour lui l’art de référence, il a toutefois su se tourner vers de nombreux autres arts. Pourquoi, même s’il ne connaissait pas, comme (...) Stanley Cavell, les comédies hollywoodiennes, ne s’est-il pas non plus, contrairement à son collègue de Lyon, Gilles Deleuze, intéressé à ce que cet art rend possible? Est-ce là une affaire de goût, alors privée et naïvement subjective? Ou ce désintérêt manifeste peut-il nous dire quelque chose de ce qu’il a cherché dans l’art, et ainsi de ce qu’on peut nommer son style philosophique? (shrink)

This article presents the Arabic text of al-Q's short geometric treatise, The Book of the centres of the tangent circles on lines, by the method of analysis, with translation and a mathematical commentary. In this treatise al-Q solves by analysis an ordered set of eight problems where the goal is to locate, on a given line, the centre of a circle which is tangent to two given elements, which may be points, straight lines or circles. For example, in the first (...) problem he wanted to find the centre of a circle which contains two given points. In fact, al-Q establishes the locus of the solutions, and this locus can be a straight line or a conic. The treatise is reminiscent of one of the purposes of al-Q's work on the perfect compass, namely to assign to the conics the status of regular lines. (shrink)

These outbreaks can be seen as a paradigm for ethical issues posed by epidemic emergencies, through the convergence of such themes as: isolation and quarantine, privacy and confidentiality and the interpretation of ethical norms across different ethnocultural settings. With an emphasis on the boundaries between public health investigations and research, this article reviews specific challenges, past practices and current normative documents relevant to the application of ethical standards in the course of outbreaks of filovirus hemorrhagic fevers. Aside from commonly identified issues of informed consent and institutional review processes, we argue for more clarity over the specification of which communities are expected to share benefits, and we advocate for the use of collective definitions of duty to care and standard of care. We propose new elaborations around existing normative instruments, and we suggest some pathways toward more comprehensive approaches to the ethics of research in outbreak situations.

We propose two alternatives to Xu’s axiomatization of Chellas’s STIT. The first one simplifies its presentation, and also provides an alternative axiomatization of the deliberative STIT. The second one starts from the idea that the historic necessity operator can be defined as an abbreviation of operators of agency, and can thus be eliminated from the logic of Chellas’s STIT. The second axiomatization also allows us to establish that the problem of deciding the satisfiability of a STIT formula without temporal operators (...) is NP-complete in the single-agent case, and is NEXPTIME-complete in the multiagent case, both for the deliberative and Chellas’s STIT.

Philosophers of science have recently focused on the scientific activity of modeling phenomena, and explicated several of its properties, as well as the activities embedded into it. A first approach to modeling has been elaborated in terms of representing a target system: yet other epistemic functions, such as producing data or detecting phenomena, are at least as relevant. Additional useful distinctions have emerged, such as the one between phenomenological and mechanistic models. In biological sciences, besides mathematical models, models now come (...) in three forms: in vivo, in vitro and in silico. Each has been investigated separately, and many specific problems they raised have been laid out. Another relevant distinction is disciplinary: do models differ in significant ways according to the discipline involved—medicine or biology, evolutionary biology or earth science? Focusing on either this threefold distinction or the disciplinary boundaries reveals that they might not be sufficient from a philosophical perspective. On the contrary, focusing on the interaction between these various kinds of models, some interesting forms of explanation come to the fore, as is exemplified by the papers included in this issue. On the other hand, a focus on the use of models, rather than on their content, shows that the distinction between biological and medical models is theoretically sound. (shrink)

The West African Ebola epidemic has set in motion a collective endeavour to conduct accelerated clinical trials, testing unproven but potentially lifesaving interventions in the course of a major public health crisis. This unprecedented effort was supported by the recommendations of an ad hoc ethics panel convened in August 2014 by the WHO. By considering why and on what conditions the exceptional circumstances of the Ebola epidemic justified the use of unproven interventions, the panel's recommendations have challenged conventional thinking about (...) therapeutic development and clinical research ethics. At the same time, unanswered ethical questions have emerged, in particular: the specification of exceptional circumstances, the specification of unproven interventions, the goals of interventional research in terms of individual versus collective interests, the place of adaptive trial designs and the exact meaning of compassionate use with unapproved interventions. Examination of these questions, in parallel with empirical data from research sites, will help build pragmatic foundations for disaster research ethics. Furthermore, the Ebola clinical trials signal an evolution in the current paradigms of therapeutic research, beyond the case of epidemic emergencies. (shrink)

ABSTRACT This paper presents the axioinatization—without the rule of irreflexivity—of the modal logic of inequality as well as a method for proving its completeness. This method uses the technics of the frame of subordination.
