Those with knowledge about scientific instruments come from many different fields. Prominent among them are (1) collectors and dealers, (2) curators, (3) historians, (4) instrument makers, (5) philosophers, and (6) scientists (the order is alphabetical, not value-laden). The annual symposium of the Scientific Instrument Commission often brings members of each of these groups together, and they learn from one another. What follows are brief reflections on the activities of each group when its members consider instruments.

The search for the Northwest Passage in the years following the Napoleonic Wars provided both a market and testing ground for marine chronometers. Long voyages and extreme temperatures challenged the best chronometers. Among the firms seeking to meet those challenges was that of William Parkinson & William James Frodsham. Their chronometers performed particularly well in the Arctic, as John and James Clark Ross, William Edward Parry, and Edward Sabine gladly recognized. The way in which chronometers were made and sold, however, (...) meant that there were sometimes controversies over who was entitled to claim credit for a particular instrument. A letter from Parkinson & Frodsham in 1821 illustrates the problem, and its causes in the nature of the trade; the text of that letter is published here in its entirety. Also problematic, and discussed here, was the craft aspect of the industry, in which the ‘mechanical construction’ of a chronometer might not reveal the process of manufacture that gave it its steady rate and accuracy.

Canada as a Neo-Europe is a relatively recent construct, although the people of its first nations, the Indians and Inuit, have been here for some twelve thousand years, since the beginning of the retreat of the last ice sheets. Western science came in a limited way with the first European explorers; Samuel de Champlain left a mariner's astrolabe behind him. The Jesuits followed with their organization and educational institutions, and from the eighteenth century science was established within European Canadian culture.

Magnetic observations were essential for polar navigation, and were carried out systematically on both sea and land-based expeditions to the Canadian Arctic throughout the nineteenth century. John Franklin took a particular interest in magnetic studies and encouraged the Admiralty to adopt Robert Were Fox's dip circle. The establishment of the Toronto magnetic observatory provided a base for John Henry Lefroy's survey of the North West Territories. The Royal Navy's programme of magnetic research, commenced in the aftermath of the Napoleonic Wars, (...) was maintained until the British Arctic Expedition of 1875–76, commanded by Nares. In all these expeditions, the nature and limits of the observations were determined by the available instruments. (shrink)

I bogen "Den store humor" undersøger Harald Høffding humoren som livsanskuelse. "Den store humor" er ifølge Høffding en etisk livsholdning, som et menneske kan leve sit liv efter. Inspireret af filosoffen Søren Kierkegaards stadieteori karakteriserer Harald Høffding humoren som et etisk standpunkt, der nægter at anerkende den kristnes tragiske syn på livet. I stedet formår humoristen, at balancere livets lyse og skyggefulde sider. Humoristen lever sit liv med åbne øjne og har derfor blik for såvel verdens komik som tragik. (...) Harald Høffding (1843-1931) var teolog og filosof og virkede gennem 30 år som professor ved Københavns Universitet. I løbet af sin karriere opnåede han en central position i det danske videns- og kulturliv og nød stor anerkendelse både i og udenfor Danmark. Høffding var yderst virksom hele sit liv, og tankegodset i hans bøger er stadig relevant i dag. Udover værkerne om etik, filosofihistorie og psykologi kendes han for monografier om Søren Kierkegaard, Jean-Jacques Rousseau og Baruch Spinoza. (shrink)

Le débat engagé dans le Phèdre à la suite des trois discours, constitue une enquête dialectique qui ne se limite pas, comme dans le Gorgias, aux seuls genres étudiés par les rhéteurs et sophistes, à savoir l'éloquence du barreau et de la tribune politique. Il examine toute la rhétorique en tant qu'art de conduire ou de provoquer l'âme. Tout discours, à quelque genre qu'il appartienne, est sujet à contradiction : en rhétorique comme en dialectique celui-là est le meilleur qui voit (...) la vérité, parce que, connaissant le pour et le contre, le vrai et le semblant de vérité, il saura défendre l'une et l'autre thèse. C'est là une doctrine reçue dans l'Académie. Pour la mettre en évidence Platon a recours à l'exemple des trois discours. Celui de Lysias, faute d'avoir établi une définition qui en soit le principe ou commencement, manque de suite et „nage à rebours". Les deux discours de Socrate posent un principe. Dans le premier une définition conventionnelle de l'amour le conduit à blâmer celui-ci, à juste titre. Vrai en lui-même, ce discours devient faux du moment qu'on lève la convention : or, dans le cas présent, il faut la lever, parce qu'elle méconnaît le divin. Sur l'intervention du „ signe" avertisseur, Socrate le corrige et le complète par le second discours, dont le principe n'est plus conventionnel et hypothétique, mais absolu : l'âme, principe moteur de tout. Nous avons ici l'antilogie parfaite qui repose sur l'unité de formes opposées, „l'un qui s'épand en multiplicité". Platon a choisi comme sujet l'amour parce que c'est lui qui, en tant qu'intermédiaire, unissant l'humain et le divin, réalise éminemment cette unité-multiplicité. L'exposé de la méthode diérétique contient bien des éléments que nous retrouverons dans les dialogues métaphysiques, mais nous aurions tort de la confondre avec celle du Sophiste, qui opère sur des notions „humaines" et a comme but de définir la forme indivisible en la cernant par une chaîne de divisions dichotomiques. Ici, grâce au mythe, il opère la jonction avec le trancendant, et il prouve que, par son caractère antilogique, le discours complet correspond à la structure de l'être un et multiple en affirmant l'unité et la contrariété des formes non-homonymes qui la constituent. Ce ne sont donc pas des exercices de dialectique formelle opérant sur de purs concepts. L'unité en question est réalisée dans l'ordre transcendant des Idées et c'est la réminiscence qui nous permet de la saisir et de reconnaître ainsi les rapports logiques et ontologiques à la fois entre les choses perçues. Cette méthode, nous devons la suivre „ pour être à même de parler et de penser". En fondant la rhétorique sur la dialectique, Platon entend reléguer au second plan les facteurs émotionnels que, sous l'influence du théâtre, la rhétorique attique d'inspiration Gorgienne avait mis en évidence comme constituant l'essence de la rhétorique. Après avoir, ici, revendiqué pour la dialectique la place qui lui revient, Socrate nous dira dans la suite ce que valent ces moyens et quel parti on peut en tirer. Il importe de bien distinguer ces deux thèses, comme Platon a eu soin de le faire. La première nous renvoie à la dialectique, la seconde à la philosophie de la nature. (shrink)

The Romance of Science pays tribute to the wide-ranging and highly influential work of Trevor Levere, historian of science and author of Poetry Realised in Nature, Transforming Matter, Science and the Canadian Arctic, Affinity and Matter and other significant inquiries in the history of modern science. Expanding on Levere’s many themes and interests, The Romance of Science assembles historians of science -- all influenced by Levere's work -- to explore such matters as the place and space of instruments in science, (...) the role and meaning of science museums, poetry in nature, chemical warfare and warfare in nature, science in Canada and the Arctic, Romanticism, aesthetics and morals in natural philosophy, and the “dismal science” of economics. The Romance of Science explores the interactions between science's romantic, material, institutional and economic engagements with Nature. (shrink)

This essay analyzes the view of evolution of Jan Lever (1922–2010), founder of the biology department at the Vrije Universiteit Amsterdam, and compares his view with those of J.H. Diemer and H. Dooyeweerd. Together with Dooyeweerd, Lever wrote a series of chapters on the species concept inPhilosophia Reformata(1948–1950) in which species were defined as constant types. In his book,Creatie en Evolutie(1956), Lever still subscribed to Dooyeweerd’s philosophy but also suggested that it is possible that biological evolution occurred, (...) including that of human beings, and that scientific research can shed light on these processes. Influenced by his idea of individuality structures, Dooyeweerd criticized Lever and suggested that species are constant; that science cannot speak to the topics that Lever discusses. It is argued that Dooyeweerd’s views are influenced by the typological thinking of the time and that reformational thought would benefit from de-emphasizing this aspect of reformational philosophy.

In lieu of an abstract, here is a brief excerpt of the content:On David Bentley Hart's Account of TraditionMatthew LeveringIn Tradition and Apocalypse, David Hart argues that "the concept of 'tradition' in the theological sense, however lucid and cogent it might appear to the eyes of faith, is incorrigibly obscure and incoherent."1 This claim coheres with the New Testament scholar Ernst Käsemann's notion of apocalyptic, as set forth in Käsemann's well known rhetorical questions—to which he answers in the negative—"Has there (...) ever been a theological system which has not collapsed? Have we been promised that we should know ourselves to be in possession of a theologia perennis?"2 For Käsemann, Christian theological "continuity" (if such there is) consists in "the hope of the manifestation of the Son of Man on his way to enthronement"3—Easter hope. Hart follows his own version of this path.Hart contends that he does not intend to overthrow the truth of the Nicene Creed.4 But he bemoans the claims of various Christian communities—Catholic, [End Page 215] Orthodox, Protestant—to have faithfully communicated the Gospel: "All Christian communions of any size or duration have their distinctive traditionalisms, their myths of continuity amidst rupture and rupture amidst continuity, their claims of doctrinal pedigree and of allegiance to the authority of the Christian past."5 Hart rejects all such ecclesial claims of dogmatic continuity and fidelity. Theologically, he deems it impossible for anyone "to say with absolute finality what the one true tradition is."6 Historically, he thinks it impossible to discern any "rational unity within the course of Christian tradition that one could confidently claim has been sustained intact amid the flux of times and cultures."7There are certain rhetorical emphases that stand out as Hart describes his own constructive view of Christian "tradition." He states that tradition is "the constant creative recollection of a promise whose fulfillment and ultimate meaning are yet to be unveiled"—not in the sense that the Church awaits the fullness that is to come and that dogmatic propositions, while true, are always inadequate to divine realities, but in the stronger sense of appealing to "a future apocalyptic horizon where the tradition's ultimate meaning is to be found" and rejecting "any reduction of that final revelation to whatever formulations of belief happen to be available at any given stage of doctrinal development." Hart depicts Christian tradition as an active transmission of a gift that remains fundamentally hidden and unknown. He invokes the image of "the impartation of a gift that remains sealed, a giving always deferred toward a future not yet known." There is a giving, but this giving is "always deferred," its future is "not yet known," and the gift itself "remains sealed." Hart argues that the "gift must remain sealed until the very end, so that the glory will not dissipate into ordinary time, whose atmosphere is incapable of sustaining and nourishing it." Time—history—cannot sustain or nourish the divine gift, and so it must be "sealed" until the end of time; and yet it can be known "in and as" ever-changing, historical tradition.8Tradition accomplishes this handing on of the sealed gift, says Hart, through its "ceaseless flow of... intertwining variations." Hart adds with regard to historicity and to "the animating impulse of the tradition": "Once that vital force has moved on to assume new living configurations, the attempt unnaturally to preserve earlier forms can achieve nothing but... the perfumed repose of a cadaver."9 The "earlier forms" that once [End Page 216] contained the "vital force" must constantly be reconfigured within tradition's "ceaseless flow."Hart pictures a destabilizing "play of tension and resolution, stability and disintegration," and he holds that we must possess a "positive desire for moments of dissolution" if we are to be faithful to "whatever is most original and most final in a tradition." Only thus can whatever is "most imperishable in a tradition... be fitfully perceived, or at least sensed," by those few persons spiritually and intellectually able to do so. By comparison, I would suggest that the core realities of faith can be much more than "fitfully perceived" or "sensed"; I think dogmatic formulations serve... (shrink)

This book is a Festschrift offered by twelve Catholic theologians and philosophers to the great Jewish theologian David Novak. Each of the twelve essays is followed by a response by David Novak, and it thereby represents a significant addition to his oeuvre. The book includes an introduction by Matthew Levering surveying Novak's many contributions to Jewish-Christian dialogue, as well as a transcribed conversation between Robert George and David Novak that encapsulates Novak's sense of the present situation for Jews and Christians. (...) Among the topics treated by the authors are religious engagement in a pluralist and secular culture, the question of whether Jews and Christians worship the same God, the morality of suicide, the role of divine commandments in Catholic moral theology, the question of whether classical versions of natural-law doctrine are susceptible to the critiques proffered by Novak, the pedagogical impact of Dabru Emet, religious freedom, the recent debate about Pope Pius IX and Edgardo Mortara, the nature of justice, the relationship of reason and revelation, the sanctity of human life and the death penalty, and supersessionism.
