This article by Curtis Wilson is an account of the origin of Hansen’s powerful systematic method for finding contributions of higher order perturbations in celestial mechanics. Hansen’s method was developed in the course of improving on Laplace’s treatment of the mutual perturbations of Jupiter and Saturn. This method, an entirely new way of doing celestial mechanics when it first appeared, later made possible the successful treatment of the complicated motions of our moon (see Wilson 2010). In this (...) paper Wilson gives a brief historical introduction followed by an account of relevant technical details of the Laplacian background, an account illustrating technical details in Hansen’s initial development in his Disquisitions of 1829, and a treatment illustrating details contributing to the achievement of Hansen’s more refined development in his Untersuchung of 1831. These details include conditional equations Hansen provides for checking the accuracy of calculations. Wilson also includes a detailed assessment showing the extraordinary improvement in empirical accuracy of Hansen’s treatment over the best earlier treatment of the Jupiter-Saturn interactions.

In lieu of an abstract, here is a brief excerpt of the content: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 painstaking precision, and an enormous background of knowledge. The letters are arranged in chronological order (with the exception of a few which are undated). Each entry lists the date, the names and locations of the sender and addressee, and the opening words of the letter. The status of the letter (original/ minute/copy/printed) is indicated, as is the library in which the letter is located (and the call number), and/or, if the letter was published, the printed source. Thirty-two libraries were explored. GIORGIO TONELLI State University o/ New York at Binghamton Introduction to Newton's Principia. By I. Bernard Cohen. (Cambridge, Mass.: Harvard University Press, 1971. Pp. xxx+380. $30.00) Over the past dozen years or so Newtonian scholarship has burgeoned as never before, and a first and fundamental result has been the publication of more and more of the wealth of manuscript material and letters that Newton left as a legacy of potential insight and confusion to future scholars. To date, the most imposing of the undertakings in publication have been The Correspondence (1959- ), begun under the editorship of H. W. Turnbull and continued more recently under that of J. F. Scott, and the Mathematical Papers (1967- ), started and continuing under the editorship of D. T. Whiteside. Selected documents of importance have been published by I. Bernard Cohen, assisted by Robert E. Schofield, in Isaac Newton's Papers and Letters on Natural Philosophy... (1958), by A. R. Hall and Marie Boas Hall in Unpublished Scientific Papers o/ Isaac Newton (1962), and by J. W. Herivel in The Background of Newton's Principia (1965); additional documentary material has appeared in studies by Alexandre Koyr6, I. Bernard Cohen, Johannes A. Lohne, D. T. Whiteside, Richard S. Wesffall, J. E. McGuire and P. M. Rattansi, and still others--a full bibliography would run to considerable length. Nor, although the uncertainties in the interpretation of the documents are sometimes overwhelming, has this spate of publication merely served to replace one set of scholarly puzzles by another. The traditional, monolithic and impenetrable image of Newton "with his prism and silent face, / The marble index of a mind for ever / Voyaging through strange seas of Thought, alone..." has lost something of its hypnotic hold, and we begin to discern some of the steps, not to say jogs and leaps, in Newton's actual journey of thought and discovery. The volume here under review introduces another major enterprise in Newtonian scholarship, a "variorum" edition of the Principia. The edition itself, which has yet to appear, will consist primarily of a facsimile reproduction of the third edition (1726)-the last edition that Newton himself supervised----collated line by line with the variant readings in the two prior editions and in a manuscript of the first edition, and with the BOOK REVIEWS 121 corrections, improvements, and additions that Newton entered into copies of the first and second editions. This textual part of the edition was delivered to the press in 1966; additional parts are in various stages of preparation. There is to be a Commentary dealing with the prefaces, definitions, laws of motion, and the first three sections of Book I and most of Book III, along with English versions and modern analytical paraphrases of the sections dealt with, a glossary, and a number of short essays on such topics as the astronomical and physical data used by Newton, the mathematical background to the understanding of the Principia, and the analysis of...

The present volume, like other volumes in this series, has the aim of introducing nonspecialists to the work of “a difficult and challenging thinker”. Galileo’s thought is often difficult to penetrate; scholars often clash in their interpretations of it.

In response to its current crisis, scholars call for the revitalisation of democracy through democratic innovations. While they make ample use of life metaphors describing democracy as a living organism, no comprehensive understanding of ‘life’ has been established within democratic theory. The Black Lives Matter (BLM) movement articulates the urgency of refocusing on life and its meaning through radical democratic practice. This article employs a grounded theory approach, enriched with participatory methods, to develop a radical democratic concept of life in (...) conversation with BLM. It conceptualises life as the existence of a perspective that constantly transforms through its fundamental interconnectedness. Building on this concept, the article outlines four principles of a living democracy that go beyond the revitalisation discourse. A living democracy (1) safeguards the existence of all humans and nonhumans, (2) nurtures a diversity of perspectives, (3) fosters social and planetary connectivity, and (4) enables self- and collective transformation.

The concept of Nothingness—Japanese mu or Chinese wú 無—is central both to the Kyoto School and to important strands of Chinese philosophy. The Kyoto School, which has been active since the 1930s, is arguably modern Japan’s most philosophically sophisticated challenge to Western thought. Further, as contemporary East Asia continues to rise in importance, East Asians and Westerners alike are beginning to consider anew the contemporary philosophical relevance of Confucianism, Daoism, and East-Asian Buddhism. These originally Chinese traditions were certainly important influences (...) directly and indirectly on Kyoto School philosophy itself. At the very least, Kyoto thought and Chinese thought share foundational structural resemblances, especially regarding the concept of Nothingness. This study summarizes the concept of Nothingness in the Kyoto School and in Chinese philosophy, and then offers an evaluation of the contemporary relevance and general coherence of this concept.

Heidegger and East-Asian thought have traditionally been strongly correlated. However, although still largely unrecognized, significant differences between the political and metaphysical stance of Heidegger and his perceived counterparts in East-Asia most certainly exist. One of the most dramatic discontinuities between East-Asian thought and Heidegger is revealed through an investigation of Kitarō Nishida’s own vigorous criticism of Heidegger. Ironically, more than one study of Heidegger and East-Asian thought has submitted that Nishida is that representative of East-Asian thought whose philosophy most closely (...) resembles Heideggerian thought. In words that then and now resound discordantly within the enshrined, established view of Heidegger’s relationship to East-Asian thought, Nishida stated uninhibitedly his own view of Heidegger in the noteworthy statement: “Heidegger is not worth your time… He…does not recognize that which is indispensible and decisive, namely, God.” This present study lays out for the first time in English, the significant differences between the metaphysical and political stances of Nishida and Heidegger, Nishida’s own critique of Heidegger, and Heidegger’s own rather dismal assessment of non-Western philosophy, all of which demonstrate a remarkable, hitherto unrecognized discontinuity between Heidegger and East-Asian thought.

Despite the central role that the concept of God played in Kitarō Nishida's philosophy—and more broadly, within the Kyoto School which formed around Nishida—Anglophone studies of the religious philosophy of modern Japan have not seriously considered the nature and role of God in Nishida's thought. Indeed, relevant Anglophone studies even strongly suggest that where the concept of God does appear in Nishida's writings, such a concept is to be dismissed as a 'subjective fiction', a 'penultimate designation', or a peripheral Western (...) intrusion with no genuine relationship to the core of Nishida's thought. However, a careful study of Nishida's own writings reveals that for Nishida, in his own words, God is 'that which is indispensable and decisive'. For the first time in English, this present study reveals Nishida's view of God, especially examining Nishida's debt to the theologian Karl Barth and Christianity. (shrink)

Evidence of an emerging focus on the role of farmer knowledge in developed countries is highlighted by the debate on the nature of local and scientific knowledge. Less attention has been paid to the interaction of different ways of knowing for sustainable capital-intensive agriculture. This paper explores the relationship between local and scientific knowledge in managing temperate pasture and grazing systems in Australia. The nature of farmer knowledge is firstly examined by describing the experiences of farm families in managing native (...) and introduced perennial grasses in upland areas of the Murray-Darling Basin. The building of knowledge and skills through social learning was explored in group case studies and interviews with stakeholders involved in pasture research and development. The interchange of local and scientific knowledge in groups was shown to have a synergistic effect, whereby local knowledge was broadened and strengthened, and scientific knowledge adapted and molded to specific situations. The effectiveness of social learning was greatest in collaborative programs based on small, local groups involved in monitoring and evaluation of whole farm pasture and grazing systems. (shrink)

There are over 2,500 Landcare groups with 65,000 members operating across Australia. With considerable evidence of program impact, Landcare is an important example of state sponsored community participation in natural resource management. However, the authors suggest excessive emphasis has been placed upon attitudinal change - the development of landholder stewardship, as the lever for effecting major changes in land management. Analysis of data from a landholder survey failed to establish predicted stewardship differences between Landcare and nonLandcare respondents or between those (...) who joined early/late, or participated more/less in group activities. And there was no relationship between stewardship and adoption for most of the sustainable agriculture practices surveyed. Further analysis clearly linked Landcare participation and concern about the environmental and economic impacts of land degradation. Whilst respondents were significantly more concerned about economic impacts, research findings were consistent with earlier work indicating that most land managers have a strong stewardship ethic. The authors also suggest that concerns that Landcare is not addressing biodiversity conservation are largely unjustified and reflect urealistic expectations of these voluntary groups. (shrink)

Die Ansicht, dass Leibniz urn 1700 oder einige Zeit danach ein überzeugter Idealist war oder wurde, der allein an die Realität der Geister und ihrer Ideen glaubte, hält sich merkwürdigerweise in der neueren Sekundärliteratur. In diesem Beitrag beurteilen wir die Textgrundlage für diese Behauptung nach von uns für solide gehaltenen Kriterien einer historischen Interpretation, wobei sich die Behauptung unserer Ansicht nach als unzureichend erweist. Obwohl Leibniz zur Überzeugung gelangt war, dass wirkliche "Atome" der Natur keine Ausdehnung hätten, war er sein (...) Leben hindurch auf die Geistesunabhängigkeit lebender Kreaturen festgelegt, in der Art, die eindeutig Idealismus ausschließt. Wir versuchen, die tieferen Gründe für die Beharrlichkeit der idealistischen Sichtweise, trotz ihrer textlichen und konzeptualen Schwierigkeiten, aufzudecken, indem wir sie letztlich in den ahistorischen Präferenzen der Kommentatoren lokalisieren.

Contract cheating refers to students paying a third party to complete university assessments for them. Although opportunities for comercial contract cheating are widely available in the form of essay mills, only about 3% of students engage in this behaviour. This study examined the reasons why most students do not engage in contract cheating. Students (n = 1291) completed a survey on why they do not engage in contract cheating as well as measures of several individual differences, including self-control, grit and (...) the Dark Triad traits. Motivation for learning and morality received the greatest endorsement for why students do not engage in contract cheating. Controlling for gender, individual differences predicted students’ reasons for not contract cheating. This study supports the use of criminological theories relating to self-control and opportunity to explain why students do not engage in contract cheating. Practically, this study may inform academic policies and assessment design that may reduce contract cheating. (shrink)

Initially identified as a key phosphoinositide that controls membrane trafficking at the Golgi complex, phosphatidylinositol‐4‐phosphate (PI4P) has emerged as a key molecule in the regulation of a diverse array of cellular functions. In this review we will discuss selected examples of the findings that in the last few years have significantly increased our awareness of the regulation and roles of PI4P in the Golgi complex and beyond. We will also highlight the role of PI4P in infection and cancer. We believe (...) that, with the increasing number of regulators and effectors of PI4P identified, the time is ripe for a more integrated approach of study. A first step in this direction is the delineation of PI4P‐centered molecular networks that we provide using data from low and high throughput studies in yeast and mammals. (shrink)

Functional diversity holds the promise of understanding ecosystems in ways unattainable by taxonomic diversity studies. Underlying this promise is the intuition that investigating the diversity of what organisms actually do—i.e. their functional traits—within ecosystems will generate more reliable insights into the ways these ecosystems behave, compared to considering only species diversity. But this promise also rests on several conceptual and methodological—i.e. epistemic—assumptions that cut across various theories and domains of ecology. These assumptions should be clearly addressed, notably for the sake (...) of an effective comparison and integration across domains, and for assessing whether or not to use functional diversity approaches for developing ecological management strategies. The objective of this contribution is to identify and critically analyze the most salient of these assumptions. To this aim, we provide an “epistemic roadmap” that pinpoints these assumptions along a set of historical, conceptual, empirical, theoretical, and normative dimensions. (shrink)

During spring of 2020, environmental ethics students at a medium sized metropolitan university in the Southeastern United States were asked to read and comment on classic essays from Robert Heilbroner and Garrett Hardin, essays regarding our responsibilities towards future generations. In general, students seemed to hold more with Heilbroner’s stance, which left room for compassion, while condemning Hardin’s harshness. Students were then asked to provide written responses stating whether they would personally sacrifice their eventual retirement in order to stop COVID-19 (...) and the reasons for their views. Responses were analyzed and categorized to detect inconsistencies between students’ described views and their willingness to personally sacrifice for the sake of others. Almost 72% of respondents asserted that they would be willing to intervene to stop the novel coronavirus by sacrificing their retirement. A fair number of respondents that stated they would sacrifice said that they would do so because they would benefit personally from the avoidance of guilt and/or from the opportunity to feel good about themselves, suggesting that even seemingly selfless behaviors are sometimes driven by egoistic motivations. Forty percent of all respondents held inconsistent views. Most notably, a number of students condemned Hardin for his lack of compassion, yet were not willing to act compassionately themselves.

In education, we are concerned with the teaching and learning of subjects, but the word “subject” can refer to the discipline being studied as well as the individual who is studying. In this essay, Teresa Strong-Wilson explores this “double entendre” of curriculum studies through the analogy afforded by German author-in-exile W. G. Sebald's working through of difficult subjects by way of semi-autobiographical writing that takes the form of an “invisible subject”: a preoccupation with an unnamed injustice entangled with his (...) own upbringing. Curriculum theory, as currere, has foregrounded the autobiographical. While the place of autobiography in curriculum studies has often been taken to mean writing, currere is more an allegorical method of study, of intellectual engagement, of learning through reading and writing, and of teaching so as to open spaces for agency. Strong-Wilson suggests that Sebald can provide a strong example for us in curriculum studies of how to ethically bring into being an allegorical, autobiographical practice focused on “invisible” subjects of deep concern.
