We examine the connections between several automorphism groups associated with a saturated differentially closed field U of characteristic zero. These groups are: Γ, the automorphism group of U; the automorphism group of Γ; , the automorphism group of the differential combinatorial geometry of U and , the group of field automorphisms of U that respect differential closure.Our main results are:• If U is of cardinality λ+=2λ for some infinite regular cardinal λ, then the set of subgroups of Γ consisting of (...) all pointwise stabilizers of Dcl's of finite subsets of U is invariant under Aut .• If U is of arbitrary infinite cardinality, then each automorphism of the differential combinatorial geometry is induced by a field automorphism of U that respects differential closure .• If U is of cardinality λ+=2λ for some infinite regular cardinal λ, then each automorphism of Γ is induced by an element of acting on Γ by conjugation .• If U is of cardinality λ+=2λ for some infinite regular cardinal λ, then the outer automorphism group of Γ is isomorphic to the multiplicative group of the rationals.

Arguably his most famous book, Moral Man and Immoral Society is Reinhold Niebuhr's important early study (1932) in ethics and politics. Widely read and continually relevant, this book marked Niebuhr's decisive break from progressive religion and politics toward a more deeply tragic view of human nature and history. Forthright and realistic, Moral Man and Immoral Society argues that individual morality is intrinsically incompatible with collective life, thus making social and political conflict inevitable. Niebuhr further discusses our inability to imagine (...) the realities of collective power; the brutal behavior of human collectives of every sort; and, ultimately, how individual morality can mitigate the persistence of social immorality. This new edition includes a foreword by Cornel West that explores the continued interest in Niebuhr's thought and its contemporary relevance. (shrink)

“[Niebuhr] is one of my favorite philosophers. I take away [from his works] the compelling idea that there’s serious evil in the world, and hardship and pain. And we should be humble and modest in our belief we can eliminate those things. But we shouldn’t use that as an excuse for cynicism and inaction. I take away... the sense we have to make these efforts knowing they are hard.”—President Barack Obama Forged during the tumultuous but triumphant postwar years when America (...) came of age as a world power, The Irony of American History is more relevant now than ever before. Cited by politicians as diverse as Hillary Clinton and John McCain, Niebuhr’s masterpiece on the incongruity between personal ideals and political reality is both an indictment of American moral complacency and a warning against the arrogance of virtue. Impassioned, eloquent, and deeply perceptive, Niebuhr’s wisdom will cause readers to rethink their assumptions about right and wrong, war and peace. “The supreme American theologian of the twentieth century.”—Arthur Schlesinger Jr., New York Times “Niebuhr is important for the left today precisely because he warned about America’s tendency—including the left’s tendency—to do bad things in the name of idealism. His thought offers a much better understanding of where the Bush administration went wrong in Iraq.”—Kevin Mattson, The Good Society “Irony provides the master key to understanding the myths and delusions that underpin American statecraft.... The most important book ever written on US foreign policy.”—Andrew J. Bacevich, from the Introduction. (shrink)

_The Children of Light and the Children of Darkness_, first published in 1944, is considered one of the most profound and relevant works by the influential theologian Reinhold Niebuhr, and certainly the fullest statement of his political philosophy. Written and first read during the prolonged, tragic world war between totalitarian and democratic forces, Niebuhr’s book took up the timely question of how democracy as a political system could best be defended. Most proponents of democracy, Niebuhr claimed, were “children of (...) light,” who had optimistic but naïve ideas about how society could be rid of evil and governed by enlightened reason. They needed, he believed, to absorb some of the wisdom and strength of the “children of darkness,” whose ruthless cynicism and corrupt, anti-democratic politics should otherwise be repudiated. He argued for a prudent, liberal understanding of human society that took the measure of every group’s self-interest and was chastened by a realistic understanding of the limits of power. It is in the foreword to this book that he wrote, “Man’s capacity for justice makes democracy possible; but man’s inclination to injustice makes democracy necessary.” This edition includes a new introduction by the theologian and Niebuhr scholar Gary Dorrien in which he elucidates the work’s significance and places it firmly into the arc of Niebuhr’s career.

Reinhold's Letters on the Kantian Philosophy is arguably the most influential book ever written concerning Kant. It provides a helpful introduction to Kant's philosophy and a valuable explanation of how that philosophy can be understood as an appropriate Enlightenment solution to the 'pantheism dispute' which dominated thought in the era of German Idealism. The first edition of Kant's Critique of Pure Reason was slow in gaining a positive reception, but after Reinhold's Letters appeared Kant's Critical Philosophy suddenly attained (...) the central position which it has held to this day. The Letters also brought fame to Reinhold, who developed his own influential 'Elementary Philosophy' and was succeeded by the leading figures of German Idealism: Fichte, Schelling, and Hegel. This English edition of Reinhold's work includes the original 1786–7 version as well as all the major additions and changes from the 1790 edition. (shrink)

This article considers the expropriation, description, and cultivation of land as a central problem for media history and political ecology. Recent work in the history and theory of media has posited the cultivation of land as a primordial cultural technique or a material operation that underlies signification. Such work stops short, however, of considering that operation—which begins with the drawing of lines on the ground—as a form of labor and hence a dimension of political economy comparable to Rousseau’s account of (...) the origin of property. John Bellamy Foster has shown how Marx’s early development of a neo-Epicurean materialism led, when informed by mid-nineteenth-century scientific agriculture, to what Foster calls Marx’s theory of “metabolic rift,” the disruption of the metabolic interchange between nature and society mediated by human labor. This article returns to the unfinished business of critical theory that rejoins the critique of culture with the critique of nature, by showing how a mediapolitics of land governs the dialectical processes described by eco-Marxists like Foster. Specifically, the article considers the material production of land for both agriculture and industry, informed by scientific agriculture and with plantation slavery as a limit case, through the work of Henry Charles Carey. Rethinking the political economy of land in this way extends the cultural materialism predominant in media history and theory into a more fully historical materialism adequate to an ecological situation in which all that may once have been solid has truly melted, or burned, into air.

This 1935 book answered some of the theological questions raised by Moral Man and Immoral Society (1932) and articulated for the first time Niebuhr's theological position on many issues.

Wie vielleicht kein anderes seiner Werke reprasentieren Reinholds Verhandlungen sein lebenslanges Bemuhen, die Aufklarung in Kooperation und Auseinandersetzung mit anderen Selbstdenkern voranzutreiben. Sie umfassen drei Beitrage. Der zweite, der Entwurf zu einem Einverstandnisse unter Wohlgesinnten, resultiert aus Diskussionen, die Reinhold mit freimaurerischen Freunden fuhrte. Hier geht es im Kern um die Frage, wie sich dem aufgeklarten Denken kantischer Pragung die notige soziale Wirkung und organisatorische Kraft verschaffen liesse. Dieser Entwurf wurde weithin an Freunde und Bekannte verschickt, mit der Bitte, (...) dem Einverstandnis beizutreten. Aber auch konstruktive Kritik erbat Reinhold. Von den Antworten, die er erhielt, druckte er neun Briefe mit seinen eigenen Repliken ab - der dritte Beitrag. Der erste Beitrag enthalt Reinholds ausfuhrliche, im Umfang stark erweiterte Umarbeitung des Entwurfs. (shrink)

Reinholds Briefe uber die Kantische Philosophie gehoren zu den wirkungsmachtigsten Produkten seines umfangreichen Schaffens. Von den Zeitgenossen teils mit grosser Begeisterung aufgenommen, tragen sie wesentlich zur Etablierung der ersten Kant-Bewegung bei. Durch ihr Bestreben, die Vernunftkritik als Theorie der moralisch-religiosen Erneuerung zu prasentieren, gelten sie als die brisanteste unter den damaligen philosophischen Neuerscheinungen. Sie sind wegweisend fur einen Kantianismus, der sich im Laufe der 1790er Jahre als eine die politischen Umwalzungen in Frankreich flankierende Geistesrevolution begreift. Der neu herausgegebene Band enthalt (...) zwolf Briefe, welche die auffallendsten Resultate von Kants Vernunftkritik ausgehend von den dringendsten wissenschaftlichen und moralischen Bedurfnissen unserer Zeit darstellen. Der Adressat erfahrt, dass mit Kants Erkenntniskritik und moralischer Neubegrundung der speziellen Metaphysik ein taugliches Mittel zur Bewaltigung gegenwartiger Grundlagenkrisen im Gebiete von Moral, Naturrecht, Theologie und Asthetik bereitsteht. Mit Nachdruck wird das problemlosende Potential von Kants moraltheologischen Resultaten hervorgehoben. In Kants Vernunftglauben und Statuierung eines moralischen Erkenntnisgrundes fur das Dasein Gottes und die Unsterblichkeit der Seele sieht Reinhold die besten Voraussetzungen fur die Beendigung einer Reihe aufklarungshemmender Debatten. Im Visier steht allem voran der als Pantheismusstreit beruhmt gewordene Disput zwischen Mendelssohn und Jacobi, in dessen Einflussbereich ein wenig ergiebiger Kampf zwischen Naturalisten und Supernaturalisten dominant werden sollte. Die Darstellung geschichtlicher Kontexte zur Idee der Unsterblichkeit der Seele und die eingehende Auseinandersetzung mit den antiken Seelenlehren kulminieren in der These, durch Kants Kritik und Neufundierung der rationalen Psychologie konne auch der bisherige, Antike und Neuzeit durchziehende Gegensatz zwischen Spiritualisten und Materialisten als aufgelost gelten. Wiederholt wird zu Reflexionen uber die Geschichte der Menschheit angesetzt, die deutlich machen, dass Reinhold das Geschichtsbild der Illuminaten mehr und mehr in Anlehnung an Lessings Idee einer kommenden Menschheitsepoche des dritten Evangeliums sowie an Kants Vision eines weltburgerlichen Endzustandes vortragt. Die Neuedition ist mit einer ausfuhrlichen Einleitung und einem Kommentar versehen. In diesen Teilen wird unter anderem auf die Entstehungsgeschichte der Briefe, auf Reinholds Kant-Rezeption sowie auf sein Kant-Verstandnis, das mit der damals gangigen Ansicht uber den Alleszermalmer kontrastiert, eingegangen. Vermerkt werden zudem inhaltlich relevante Abweichungen von fruheren Fassungen der in den Band von 1790 eingeflossenen Textteile. (shrink)

Traditionally, the impairment of cognitive functions in Alzheimeŕs disease (AD) is thought to result from a reduction in neuronal and synaptic activities, and ultimately cell death. Here, we review recent in vivo evidence from mouse models and human patients indicating that, particularly in early stages of AD, neuronal circuits are hyperactive instead of hypoactive. Functional analyses at many levels, from single neurons to neuronal populations to large‐scale networks, with a variety of electrophysiological and imaging techniques have revealed two forms of (...) AD‐related hyperactivity and provided first insights into the synaptic mechanisms. The unexpected finding that hyperactivity is an early neuronal dysfunction represents a major conceptual shift in our understanding of AD that may have important implications for the development of therapeutic approaches.

Some twenty years after the Gregorian calendar reform, towards the end of his life, François Viète published his own calendar proposal. This treatise contains a sharp attack against the Jesuit scholar Clavius, the mathematical mind behind the reform. Understandably enough, Clavius prepared a negative reply. Viète heard of it and exploded in a fit of rage, ``I demonstrated that you are a false mathematician [... ], and a false theologian.'' Sadly, Clavius' rejection, added as a chapter to his monumental apology (...) of the Gregorian reform, appeared when Viète had already passed away.Viète seriously believed that the true aim of the Gregorian reform has been betrayed and he was furious about some logical inconsistencies which he claimed to have found in Clavius' calendar. Clavius apparently confused solar day and epactal day (or ``tithi''), the thirtieth part of a lunar month. This is the very core of Viète's attack against Clavius whom he accused of having introduced a false lunar period (``falsa periodus lunaris''). But his own work has some logical inconsistencies too. For instance, he reproaches Clavius for having introduced lunar months of 31 days which, indeed, are unrealistic. Grievously, his own rules can likewise give rise to lunations of unnatural lengths.In order to understand these subtle twists reader and author must work largely through both Clavius and Viète's methods of Easter reckoning. The fruit of all those efforts might be an insight into Viète's clear mathematical thinking. His calendar, however, was never considered. (shrink)

Volume V covers the period from September 1530 to May 1531. It therefore mainly contains information about Bucer¹s diplomatic journey after the Augsburg Diet, his correspondence with the Valdesian synod of Mérindol, his attempts to mediate between Luther and Zwingli with the help of his Konkordienschrift and to integrate the Swiss party in the Schmalcaldic confederation.

We question the assumption of serial attention shifts and the assumption that saccade programs are initiated or canceled only after stage one of word identification. Evidence: (1) Fixation durations prior to skipped words are not consistently higher compared to those prior to nonskipped words. (2) Attentional modulation of microsaccade rate might occur after early visual processing. Saccades are probably triggered by attentional selection.
