We claim that, as it stands, the Deutsch–Wallace–Everett approach to quantum theory is conceptually incoherent. This charge is based upon the approach’s reliance upon decoherence arguments that conflict with its own fundamental precepts regarding probabilistic reasoning in two respects. This conceptual conflict obtains even if the decoherence arguments deployed are aimed merely towards the establishment of certain ‘emergent’ or ‘robust’ structures within the wave function: To be relevant to physical science notions such as robustness must be empirically grounded, and, on (...) our analysis, this grounding can only plausibly be done in precisely the probabilistic terms that lead to conceptual conflict. Thus, the incoherence problems presented necessitate either the provision of a new, non-probabilistic empirical grounding for the notions of robustness and emergence in the context of decoherence, or the abandonment of the Deutsch–Wallace–Everett programme for quantum theory.

The subjective Everettian approach to quantum mechanics presented by Deutsch and Wallace fails to constitute an empirically viable theory of quantum phenomena. The decision theoretic implementation of the Born rule realized in this approach provides no basis for rejecting Everettian quantum mechanics in the face of empirical data that contradicts the Born rule. The approach of Greaves and Myrvold, which provides a subjective implementation of the Born rule as well but derives it from empirical data rather than decision theoretic arguments, (...) avoids the problem faced by Deutsch and Wallace and is empirically viable. However, there is good reason to cast doubts on its scientific value. (shrink)

We provide an analysis of the empirical consequences of the AdS/CFT duality with reference to the application of the duality in a fundamental theory, effective theory and instrumental context. Analysis of the first two contexts is intended to serve as a guide to the potential empirical and ontological status of gauge/gravity dualities as descriptions of actual physics at the Planck scale. The third context is directly connected to the use of AdS/CFT to describe real quark-gluon plasmas. In the latter context, (...) we find that neither of the two duals are confirmed by the empirical data. (shrink)

The study of the autonomic nervous system (ANS) function has shown to provide useful indicators for risk stratification and early detection on a variety of cardiovascular pathologies. However, data gathered during different tests of the ANS are difficult to analyse, mainly due to the complex mechanisms involved in the autonomic regulation of the cardiovascular system (CVS). Although model-based analysis of ANS data has been already proposed as a way to cope with this complexity, only a few models coupling the main (...) elements involved have been presented in the literature. In this paper, a new model of the CVS, representing the ventricles, the circulatory system and the regulation of the CVS activity by the ANS, is presented. The models of the vascular system and the ventricular activity have been developed using the Bond Graph formalism, as it proposes a unified representation for all energetic domains, facilitating the integration of mechanic and hydraulic phenomena. In order to take into account the electro-mechanical behaviour of both ventricles, an electrophysiologic model of the cardiac action potential, represented by a set of ordinary differential equations, has been integrated. The short-term ANS regulation of heart rate, cardiac contractility and peripheral vasoconstriction is represented by means of continuous transfer functions. These models, represented in different continuous formalisms, are coupled by using a multi-formalism simulation library. Results are presented for two different autonomic tests, namely the Tilt Test and the Valsalva Manoeuvre, by comparing real and simulated signals. (shrink)

Dialogic leadership as ethics method respects, values, and works toward organizational objectives. However, in those situations where there may be conflicts and/or contradictions between what is ethical and what is in the material interest of individuals and/or the organization, the dialogic leader initiates discussion with others (peers, subordinates, superiors) about what is ethical with at least something of a prior ethics truth intention and not singularly a value neutral, constrained optimization of organizational objectives. Cases are considered where dialogic leadership: (1) (...) helped build ethical organizational culture; (2) was effective; and, (3) as a by-product, produced integrative win-win results. Philosophical foundations for the method as well as differences between dialogic leadership and Theory X forcing leadership, Theory Y win-win integrative leadership, industrial democracy, participative management, action inquiry, and double-loop learning action science are explored. Limitations of the method are also explored. (shrink)

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

In the svārthānumāna chapter of his Pramāṇavārttika, the Buddhist philosopher Dharmakīrti presented a defense of his claim that legitimate inference must rest on a metaphysical basis if it is to be immune from the risks ordinarily involved in inducing general principles from a finite number of observations. Even if one repeatedly observes that x occurs with y and never observes y in the absence of x, there is no guarantee, on the basis of observation alone, that one will never observe (...) y in the absence of x at some point in the future. To provide such a guarantee, claims Dharmakīrti, one must know that there is a causal connection between x and y such that there is no possibility of y occurring in the absence of x. In the course of defending this central claim, Dharmakīrti ponders how one can know that there is a causal relationship of the kind necessary to guarantee a proposition of the form “Every y occurs with an x.” He also dismisses an interpretation of his predecessor Dignāga whereby Dignāga would be claiming non-observation of y in the absence of x is sufficient to warrant to the claim that no y occurs without x. The present article consists of a translation of kārikās 11–38 of Pramānavārttikam, svārthānumānaparicchedaḥ along with Dharmakīrti’s own prose commentary. The translators have also provided an English commentary, which includes a detailed introduction to the central issues in the translated text and their history in the literature before Dharmakīrti.

S There is a long tradition of representing causal relationships by directed acyclic graphs (Wright, 1934 ). Spirtes ( 1994), Spirtes et al. ( 1993) and Pearl & Verma ( 1991) describe procedures for inferring the presence or absence of causal arrows in the graph even if there might be unobserved confounding variables, and/or an unknown time order, and that under weak conditions, for certain combinations of directed acyclic graphs and probability distributions, are asymptotically, in sample size, consistent. These results (...) are surprising since they seem to contradict the standard statistical wisdom that consistent estimators of causal effects do not exist for nonrandomised studies if there are potentially unobserved confounding variables. We resolve the apparent incompatibility of these views by closely examining the asymptotic properties of these causal inference procedures. We show that the asymptotically consistent procedures are ‘pointwise consistent’, but ‘uniformly consistent’ tests do not exist. Thus, no finite sample size can ever be guaranteed to approximate the asymptotic results. We also show the nonexistence of valid, consistent confidence intervals for causal effects and the nonexistence of uniformly consistent point estimators. Our results make no assumption about the form of the tests or estimators. In particular, the tests could be classical independence tests, they could be Bayes tests or they could be tests based on scoring methods such as  or . The implications of our results for observational studies are controversial and are discussed briefly in the last section of the paper. The results hinge on the following fact: it is possible to find, for each sample size n, distributions P and Q such that P and Q are empirically indistinguishable and yet P and Q correspond to different causal effects.

In lieu of an abstract, here is a brief excerpt of the content:264 HISTORY OF PHILOSOPHY right at hand, without getting in the way. If it had been printed in as readable type and as elegant form as Steinmann's edition, it might be the ideal easily accessible version to familiarize us with the Pens~es as they were actually written and classified by Pascal himself. RICHARD H. POPKIN University of California, San Diego Pascal. Quinta edizione riveduta e aumentata. By Michele (...) Federico Sciacca. (Milano: Carlo Marzorati Editore, 1962. Pp. 250. 2000 L.) This Pascal by Sciacca consists of three parts. The first gives and considers the Life of Pascal (1623-1662) in connection with his complex and restless century (pp. 13--72). The second part (pp. 75-112) analyzes the relationship of Pascal with Jansenism. Pascal is both dependent on and independent of it. The Jansenists discussed while Pascal felt. Jansenism could not find a stable equilibrium between nature and grace which Jansenism either contrasted or confused while Pascal well distinguishes these two orders. They are for him heterogeneous but the lower order leads to the higher. Without God, man is misery and darkness. With God, man can do all things (p. 118). The third part (pp. 115-219) is entitled The Christian Philosopher. It shows that man is made for the infinite. The true call of humanity is religious (p. 206). The final conclusion is that Pascal can still teach us to exist (p. 216). PAUL Y. FUHRMANN Columbia Theological Seminary Louis Thomassin (1619-95), ~tude bio-bibliographique avec vingt lettres et deux textes in~dits. By Pierre Clair. (Vol. I of the series Le mouvement des idles au XVH" si~cle, Collection dirig~e par Andr~ Robinet.) (Paris: 1964. Pp. 160. NF 12.) This small volume is the first in a new series devoted to bringing to light various figures and aspects of seventeenth-century thought that have either been set aside, forgotten, or are only dimly known. Louis Thomassin (as well as Bernard Lamy who is the subject of the second volume that has appeared in this series) certainly falls in these categories. Although his name often turns up in discussions of Cartesianlsm, Jansenism, Malebranchism, etc., very little consideration is ever given to him as a fairly important personage of the time, or to his ideas and the role they played. This volume by Dr. Clair will be of much use to seventeenth-century scholars in providing the basic data about his life, his connections with several of the vital movements of the period, the fundamental bibliographical materials, as well as publishing two texts and twenty letters not before available. The biographical section (pp. 1-84) traces (a bit too episodically) Thomassin's education, his career among the Oratorians as a professor of humanities, philosophy, and theology, his possible involvements with the Jansenists, his difficulties as a result of his first published work, Dissertations sur les Conciles (1667) (suppressed the same year), his later successes for his many other works in theology, philosophy, history, and pedagogy, and his relations with various major and minor figures of the mid- and late seventeenth century, like Arnauld, Malebranche, Richard Simon, Bayle, Huet, etc. Section II (pp. 85-99) gives a detailed bibliography of Thomassin's published works, plus a list of his manuscripts located in various French libraries. This is followed by twenty letters of Thomassin, an intriguing and interesting discourse on the difference between history and science, and one on the nature of chronology, plus three letters by Thomassin's secretary, Nicolas Barat. In a brief BOOK REVIEWS 265 concluding chapter (pp. 150-52), Dr. Clair deals with "Comment lire l'oeuvre du P. Thomassin," providing much guidance to anyone who wishes to avail himself of the rich resources in Thomassin's writings. From the point of view of the history of philosophy, the most interesting aspects of Thomassin's thought seem to be (1) his "Cartesianism," that is, the extent to which he early imbibed Descartes' new ideas, and played a role in the fusion of the views of Augustine, B6rulle, and Descartes that developed in the Oratory, (2) his attempt to find a viable theory of the nature of Grace somewhere between Arnauld and Malebranche, and (3) his...

In lieu of an abstract, here is a brief excerpt of the content:Ephraim Chambers’s Cyclopædia (1728) and the Tradition of CommonplacesRichard YeoIn the fifth volume (1755) of the Encyclopédie in his entry on “En-cyclopædia,” Denis Diderot forecast a time in which the sheer number of books would require a division of intellectual labor. Some people, he said, will not do much rea ding but rather “devote themselves to investigation which will be new, or which they will believe to be new.” (...) The majority, unable to produce anything of their own, “will be busy night and day leafing through these books, taking out of them the fragments they consider worthy of being collected and preserved.” 1 Although Diderot set this prospect in the future, he believed the signs were already visible and offered his encyclo-pædia as a response. Part of this image, however—the selection of passages from a range of authors—was already a familiar one. Re commended by the Ancients, it was widely practised during the Renaissance by the educated elite who kept commonplace books for recording quotations on various themes from Classical authors. Even the epigram from Horace on the title page of the Encyclop édie suggests this lineage: “What grace may be added to commonplace matters by the power of order and connection.” 2In the classical period, the Latin term, locus communis, referred to a general argument capable of being used in different situations. In his Institutiones Oratoriae Quintilian discussed the notion of copia verborum in connection with the ability of a good orator to produce copious illustrations [End Page 157] and embellishments from particular ideas. Renaissance writers thought this facility was enhanced by a record of similar ideas in the same place in a notebook. This practice had been followed in the medieval period, but it became more systematically taugh t as part of rhetoric from the sixteenth century. Commenting on this, R. R. Bolgar wrote:The whole purpose of the Humanists in transmogrifying Greek and Latin literature into a series of notes was to produce a body of material which could be easily retained and repeated. They made titanic efforts to remember the contents of the note-books the y compiled. 3Quintilian’s work, and more immediately, that of the German humanist, Rudolph Agricola, influenced Erasmus in his De Copia, first published in 1512 as De Duplici Copia Verborum ac Rerum Commentarii Duo. This offered advice on how to collect words and passages under various topoi or loci (places) as a means of storing extracts from books that could later be brought together and embellished in either writing or conversation. The set of ideas or themes grouped under one “Head” wer e known as “common-places,” and the notebooks kept for this purpose were commonplace books. 4 These were also called “copie” books in the sense of collections enabling copia, or free flow of material for oratory. Versions of this practice continued into the nineteenth century: figures such as John Milton, George Berkeley, Robert Southey, R obert Burns, and David Thoreau kept commonplace books, some of which were subsequently published. Some of these included less than elevated content: Kenneth Lockridge has uncovered a string of misogynist remarks and anecdotes in the commonplace book of Th omas Jefferson. 5In the only major study of the commonplace tradition, Sister Joan Marie Lechner analyzed its status in Renaissance rhetorical training from the sixteenth to the early seventeenth century, identifying some confusion and [End Page 158] tensions, partly as result of dissatisfaction with the “doctrine of places” taught by classical writers, and also because “commonplace” had come to refer both to a “locus or seat of arguments” and a “speech-within-a-speech.” 6 Her work shows that commonplace books were kept as aids to recall reading and as storehouses (thesauri) of topics and phrases suitable for speeches and conversation, as recommended by Erasmus and other writers. However, Lechner noted a new need pa rtly satisfied by the commonplace collections, which was that they accommodated Renaissance passions for “accumulating universal knowledge.” Thus, in her words:The commonplace book with its encyclopaedic array of topics or places was thought of as a compend of knowledge displayed in a systematic pattern...

Après les traités 38, 50 et 25, les Éditions du Cerf récidivent avec un nouveau titre, le traité 20 Sur la dialectique. Il faut toutefois aborder ce livre d’une manière toute spéciale, car il se distingue radicalement des autres parutions de cette collection. L’auteur, Vladimir Jankélévitch, s’est en effet éteint à Paris en 1985, à l’âge de quatre-vingt-deux ans. Le travail qu’on offre au public prend donc la forme d’un hommage posthume à ce philosophe français dont les publications s’étendent sur (...) cinquante ans, de 1924 à 1974. C’est précisément sa toute première composition d’importance, celle de 1924 lors de son diplôme d’études supérieures, qui s’ajoute désormais à l’ensemble de ses écrits et permettra de voir à quel état d’élévation se trouvait alors sa pensée du haut de ses vingt ans. L’édition moderne qu’on en propose respecte autant que possible l’original manuscrit. Par exemple, toutes les annotations que fit Émile Bréhier en marge du travail de son étudiant apparaissent au bas des pages. Même les quelques erreurs de langage subsistent dans leur intégralité. Nos attentes doivent alors s’ajuster au type de travail qu’on s’apprête à lire. En tant que relique et témoignage d’une intelligence en plein développement, il prend une tout autre tangente que les ouvrages plus matures qu’a écrits P. Hadot sur les traités 38 et 50. La division de la recherche en introduction, traduction et commentaire, si constante d’un livre à l’autre, s’évanouit dans le traité Sur la dialectique. On n’y trouve aucune traduction et seulement un commentaire plus ou moins suivi sur la seconde moitié du traité. Le lecteur fera bien de se munir au préalable de son édition de Plotin chez Les Belles Lettres, afin de se rafraîchir au besoin la mémoire sur le traité I, 3. (shrink)

To demarcate the limits of experimental knowledge, we probe the limits of what might be called an experiment. By appeal to examples of scientific practice from astrophysics and analogue gravity, we demonstrate that the reliability of knowledge regarding certain phenomena gained from an experiment is not circumscribed by the manipulability or accessibility of the target phenomena. Rather, the limits of experimental knowledge are set by the extent to which strategies for what we call ‘inductive triangulation’ are available: that is, the (...) validation of the mode of inductive reasoning involved in the source-target inference via appeal to one or more distinct and independent modes of inductive reasoning. When such strategies are able to partially mitigate reasonable doubt, we can take a theory regarding the phenomena to be well supported by experiment. When such strategies are able to fully mitigate reasonable doubt, we can take a theory regarding the phenomena to be established by experiment. There are good reasons to expect the next generation of analogue experiments to provide genuine knowledge of unmanipulable and inaccessible phenomena such that the relevant theories can be understood as well supported. This article is part of a discussion meeting issue ‘The next generation of analogue gravity experiments’. (shrink)

Seeing philosophy as conversation with a number of fruitful avenues of discourse, Rorty seems to be caught in limbo, unwilling to follow through or commit himself to any particular line of discourse for fear of closing himself off to alternative discourses. Choosing to adopt this particular attitude he still has made a choice: he has made a commitment to non-commitment, or as Ortega puts it, “decided not to decide.” Jose Ortega y Gasset, The Revolt of the Masses, trans. anonymously (New (...) York: W.W. Norton & Company, 1957), p. 48. Such a commitment or decision is in no way neutral, for it attempts to enforce, by moral requirement, Richard Rorty, Philosophy and the Mirror of Nature, p. 394. a new vocabulary which views philosophy as conversation between speakers, with a whole range of obligations and implications included. Thus the Rortian alternative, like the alternatives he criticizes, plays the role “of the cultural overseer who knows everyone's common ground — the Platonic philosopherking who knows what everybody else is really doing whether they know it or not, because he knows about the ultimate context ... within which they are doing it.” Ibid., pp. 317–318. In fact, Rorty even refers to “conversation as the ultimate context” Ibid., p. 389. In assuming to know everyone's common ground, that every-one is participating in the conversation of humankind whether they realize it or not, Rorty seems to fall prey to a similar “self-deceptive ... absurdity of thinking that the vocabulary [he uses] ... has some privileged attachment to reality which makes it more than just a further set of descriptions.” Ibid., p. 361.One implication of such a position is that despite its holder's claims that he or she will at least attempt to incorporate abnormal discourses of all sorts, the conversationalist will not be able to consider seriously a number of types of discourse. If the edifying, hermeneutical philosopher were really “willing to pick up the jargon of the interlocutor rather than translating it into his own terms,” Ibid., p. 318. it would often be necessary to drop the notion of conversation as being a fundamental practice or moral obligation. Rorty is obviously unwilling to really pick up the jargon of the epistemologist and the meta-physician he criticizes, or of Nietzsche and Stirner, for each of these does not have contained within them, at least as a primary consideration, the continuing of the conversation of humankind. Because he imposes his vocabulary and descriptions on them - they are merely speakers in a conversation - he will see them as merely threads in a larger social fabric, he will be translating their “jargon” into his own, and thus will never be able to take their position seriously, never be prepared to adopt their position as his own. Being possessed by the notion of continuing the conversation, he is closing himself off to traditional epistemological and metaphysical projects, as well as to the perspectives of thinkers like Stirner and Nietzsche, despite his claim to be open to all of them. He can only consider them as topics of conversation as long as he remains committed to conversation, and thus never consider them as live options, or consider them as alternative life-projects to be pursued on their own terms. In insisting on the moral obligation of philosophers to continue the conversation of the West, he is insisting on the moral obligation of philosophers not to whole-heartedly adopt any of the alternatives which would tend to close off this conversation. Therefore, instead of decrying “the very notion of having a view, while avoiding having a view about having views,” Ibid., p. 371. Rorty has a rather clear view about having views: one should not hold any view whole-heartedly except the view that philosophy should be conversation, and this conversation should be the way to decide among views; that is, the way to decide among all views except the view that conversation should be the way to decide, which for Rorty is not open to discussion, but is a moral obligation. All perspectives are encouraged in the conversation, but the conversational morality has already prescribed that these views should not be whole-heartedly adopted by responsible individuals. Requiring that philosophy be conversation, Rorty closes off numerous possible life-styles, and almost all traditional philosophical projects: he merely saves the appearances of these alternatives. Morally required to continue the conversation, philosophy becomes just talk. Along the same lines, when Rorty claims that the normal and abnormal discourses “do not compete, but rather help each other out,” Ibid., p. 346. he assumes that the epistemological and metaphysical discourses will be helped by various abnormal discourses, and assumes thinkers like Nietzsche and Stirner will be helped by being made to see the significance of societies which have fallen together and are united by civility. Yet, in doing this, Rorty is not attempting to understand - either sympathetically or intellectually - what it would mean to help these projects on their own terms, and as such is not trying to understand and assimilate these alternatives as he claims he is. Rather, he is holding each of these alternatives up to his own ideal of an “open conversation,” and judging what it would mean to “help out” these alternatives only according to his own particular standards. In continually translating what others are offering into his own particular frame of reference, he does not appreciate these philosophical alternatives for their worth as individual activities which can contribute to life and/or society, but values them only for what they can contribute to his larger project, the conversation of humankind. However, if these alternatives were taken seriously, then they would surely be seen to compete with his view which advocates social criteria for adjudicating disputes, thereby denying many of the fundamental aspects of the above-mentioned alternative philosophical under-takings. It should be seen that contrary to what Rorty suggests, edification also “provides only some, among many, ways of describing ourselves,” Ibid., p. 361. and is only one type of human project among many others. In suggesting that we shift our focus “from the relation between human beings and the objects of their inquiry to the relation between alternative standards of justification, and from there to the actual changes in these standards which make up intellectual history,” Ibid., pp. 389–390. Rorty neither breaks free from traditional concerns, nor brings the focus of attention onto our own lives. As Bernstein notes, “there is a sense in which Rorty himself is obsessed. It is almost as if he can't quite ‘let go’ and accept the force of his own critique. It is as if Rorty himself has been more deeply touched by what he is attacking than he realizes.... He himself is obsessed with the obsessions of philosophers.” R.J. Bernstein, “Philosophy in the Conversation of Mankind,” pp. 767, 775.As a result of this, Richard Eldridge correctly notes that Rorty is unable to realize that “[c]riticism matters just insofar as it enables us fruitfully to develop our lives and our practices out of the past.” Richard Eldridge, “Philosophy and the Achievement of Community: Rorty, Cavell and Criticism,” Metaphilosophy 14, No. 2 (1983), p. 124. As an alternative to the Rortian attitude, I invite the reader to entertain a perspective which is not primarily concerned with identifying oneself in accordance with, or in opposition to, particular traditions, but rather with assimilating and utilizing all previous philosophical labors in order to achieve the greatest appreciation of one's own personal possibilities, and the fullest expression of one's own powers.

We introduce ‘model migration’ as a species of cross-disciplinary knowledge transfer whereby the representational function of a model is radically changed to allow application to a new disciplinary context. Controversies and confusions that often derive from this phenomenon will be illustrated in the context of econophysics and phylogeographic linguistics. Migration can be usefully contrasted with concept of ‘imperialism’, that has been influentially discussed in the context of geographical economics. In particular, imperialism, unlike migration, relies upon extension of the original model (...) via an expansion of the domain of phenomena it is taken to adequately described. The success of imperialism thus requires expansion of the justificatory sanctioning of the original idealising assumptions to a new disciplinary context. Contrastingly, successful migration involves the radical representational re-interpretation of the original model, rather than its extension. Migration thus requires ‘re-sanctioning’ of new ‘counterpart idealisations’ to allow application to an entirely different class of phenomena. Whereas legitimate scientific imperialism should be based on the pursuit of some form of ontological unification, no such requirement is need to legitimate the practice of model migration. The distinction between migration and imperialism will thus be shown to have significant normative as well as descriptive value. (shrink)

This fourth edition of one of the classic logic textbooks has been thoroughly revised by John Burgess. The aim is to increase the pedagogical value of the book for the core market of students of philosophy and for students of mathematics and computer science as well. This book has become a classic because of its accessibility to students without a mathematical background, and because it covers not simply the staple topics of an intermediate logic course such as Godel's Incompleteness Theorems, (...) but also a large number of optional topics from Turing's theory of computability to Ramsey's theorem. John Burgess has now enhanced the book by adding a selection of problems at the end of each chapter, and by reorganising and rewriting chapters to make them more independent of each other and thus to increase the range of options available to instructors as to what to cover and what to defer.

Installation and initial setup of the device is simple. It is only necessary to measure and enter in the device height of its (...) arrangement. In the article the possibility of using a smartphone with an integrated set of necessary technical means for implementing the technology of video recording of vehicle speed is investigated and established. The smartphone has a low cost and power consumption, the ability to operate in the required temperature range, as well as a set of physically built-in necessary technical means: several video cameras, accelerometers, gyroscope, magnetometer, GPS sensor, GSM and Wi-Fi wireless communication. Due to its low power consumption, it can also run on solar panels during the day when no other power source is available. The cost of a smartphone with very good characteristics does not exceed 10,000 UAH. The paper proposes the main components of the algorithmic support of the device. The use of the Lucas-Kanade method for the implementation of tracking and the calculation in the interpixel space of the coordinates of the points of the vehicle's trajectory will improve the accuracy of measurements of the traveled distance and the vehicle's speed on short sections of the trajectory. The proposed algorithm for calculating the vehicle speed requires entering only one parameter - the height of the device. Therefore, installation and initial setup of the device is simple. It is enough to measure and enter this parameter into the device. Large-scale introduction of a device for measuring vehicle speed, built on the basis of a smartphone, is possible due to relatively small investments in the development of its mechanical part, algorithmic and software.

In this article, I examine Luhmann’s, Bunge’s and others’ views on emergence, and argue that Luhmann’s epistemological construal of emergence in terms of Totalausschluss (total exclusion) is both ontologically flawed and detrimental to an appropriate understanding of the distinctive features of social emergence. By contrast, Bunge’s rational emergentism, his CESM model, and Wimsatt’s characterization of emergence as nonaggregativity provide a useful framework to investigate emergence. While researchers in the field of social theory and sociology tend to regard Luhmann as the (...) sole representative of systems theory, the latter has been characterized by its diversity, and the writings of such systems theorists as Mario Bunge deserve more (critical) attention from social researchers than they receive at present. Finally, this article suggests that the perennial debate over methodological individualism and holism in social science may make real progress if such ambiguous terms as reduction and reductionism are elucidated before they are employed.

This essay grows out of the conviction that recent work by psychologists studying human reasoning has important implications for a broad range of philosophical issues. To illustrate our thesis we focus on Nelson Goodman's elegant and influential attempt to "dissolve" the problem of induction. In the first section of the paper we sketch Goodman's account of what it is for a rule of inference to be justified. We then marshal empirical evidence indicating that, on Goodman's account of justification, patently invalid (...) inferential rules turn out to be "justified." We conclude that something is seriously wrong with Goodman's story about justification. In the second section we attempt to patch Goodman's account. The notion of epistemic authority and the social aspect of justification play central roles in the alternative account of justification that we propose. (shrink)

A possible solution is offered to help resolve the “two times problem” regarding the veridical and illusory nature of time. First it is recognized that the flow of time is part of a wider array of temporal experiences referred to as manifest time, all of which need to be reconciled. Then, an information gathering and utilizing system model is used as a basis for a view of manifest time. The model IGUS robot of Hartle that solves the “unique present” debate (...) is enhanced with veridical and illusory components of not only the flow of time but also the larger entity of manifest time, providing a dualistic IGUS robot that represents all of the important temporal experiences. Based upon a variety of prior experiments, that view suggests that the veridical system is a reflection of accepted spacetime cosmologies and through natural selection begets the illusory system for functional purposes. Thus, there are not two opposing times, one outside and one inside the cranium. There is just one fundamental physical time which the brain developed, now possesses and is itself sufficient for adaption but then enhances. The illusory system is intended to provide a more satisfying experience of physical time, and better adaptive behavior. Future experiments to verify that view are provided. With a complete veridical system of temporal experiences there may be less need to reify certain temporal experiences so that the two times problem is less of a problem and more of a phenomenon.

On one popular view, the general covariance of gravity implies that change is relational in a strong sense, such that all it is for a physical degree of freedom to change is for it to vary with regard to a second physical degree of freedom. At a quantum level, this view of change as relative variation leads to a fundamentally timeless formalism for quantum gravity. Here, we will show how one may avoid this acute ‘problem of time’. Under our view, (...) duration is still regarded as relative, but temporal succession is taken to be absolute. Following our approach, which is presented in more formal terms in, it is possible to conceive of a genuinely dynamical theory of quantum gravity within which time, in a substantive sense, remains. 1 Introduction1.1 The problem of time1.2 Our solution2 Understanding Symmetry2.1 Mechanics and representation2.2 Freedom by degrees2.3 Voluntary redundancy3 Understanding Time3.1 Change and order3.2 Quantization and succession4 Time and Gravitation4.1 The two faces of classical gravity4.2 Retaining succession in quantum gravity5 Discussion5.1 Related arguments5.2 Concluding remarks.

The second edition of Aquinas, _On Law, Morality, and Politics _ retains the selection of texts presented in the first edition but offers them in new translations by Richard J. Regan--including that of his Aquinas, _Treatise on Law_. A revised Introduction and glossary, an updated select bibliography, and the inclusion of summarizing headnotes for each of the units--Conscience, Law, Justice, Property, War and Killing, Obedience and Rebellion, and Practical Wisdom and Statecraft—further enhance its usefulness.
