At the end of the twentieth century, the Ayatollah Marʿashī Najafī Library acquired a fourteenth-century manuscript of munshaʾāt previously held in a private collection. This composite multitext manuscript contains about two hundred letters sent by or to officials of the Rūm Saljūq sultanate in the thirteenth century. The letters include official and private correspondence as well as decrees of nomination. They are all in Persian. This article is a first study of the codicological features, structure, and contents of this manuscript. (...) It suggests a production process that unfolded in several stages over a period of seventy years, from the reign of Ghiyāth al-Dīn Kay-Khusraw II to the second decade of the fourteenth century. The Marʿashī manuscript expands considerably the volume of documents available on Saljūq Anatolia during the beginning of Mongol period. It is poised to become a major source on the political history of the period and will also help to understand the integration of Anatolia into the Persianate sphere. (shrink)

Binding of antigen or lectin to the surface of a T lymphocyte initiates a complex sequence of events which result in both T cell proliferation and the acquisition of immunologic functions. This complex sequence of events is most likely programmed and precisely timed by a series of contingent gene activations in which one member of this series activates the next. The two most obvious examples of these stages are the set of genes activated when antigen interacts with the antigen receptor (...) and the set of genes activated when IL‐2 interacts with its receptor. However, it is likely that several other parallel pathways of gene activation are necessary to bring about T‐cell division. An example would be the antigen‐induced activation of the c‐myc gene, which in turn is likely to be involved in regulating an additional group of genes not directly controlled by either IL‐2 or antigen. A fundamental understanding of T‐lymphocyte activation necessitates identification of the factors involved in initiating each of these contingent levels of gene activation. (shrink)

De 1815 - avec le Congrès de Vienne qui inaugure une ère de Restauration - à mars 1848, avec les répercussions de la révolution de février en Europe, la période du Vormârz ("avant mars") se caractérise, au sein du monde germanique, par une vie intellectuelle d'une particulière effervescence. Les grandes philosophies qui se sont construites pour dépasser Kant, avec Fichte, Schelling et Hegel, autorisent bon nombre de penseurs allemands à considérer l'Allemagne comme étant philosophiquement en avance sur son temps, ou (...) tout au moins à la pointe de la modernité. Cette avance théorique tranche pourtant avec la réalité politique et sociale de l'époque, façonnée par Metternich. Une solution de cette contradiction dans laquelle se trouve l'Allemagne semble alors résider, aux yeux de certains auteurs, dans l'idée suivant laquelle il ne resterait plus à l'Allemagne qu'à réaliser sa philosophie. Le présent ouvrage entend contribuer à l'analyse de la façon dont le thème de la réalisation de la philosophie est élaboré par, ou à partir des réflexions de plusieurs auteurs de l'époque. Il s'agit des Jeunes Hégéliens, et principalement : Eduard Gans, Heinrich Heine, Arnold Ruge, Ludwig Feuerbach, Max Stirner, David Strauss, les frères Bruno et Edgar Bauer, Moses Hess, Michel Bakounine, August von Cieszkowski, Karl Marx et Friedrich Engels."--Page 4 of cover.

Si l’histoire des mobilités étudiantes constitue actuellement un champ de recherche dynamique, certains programmes de bourses internationales ont davantage été étudiés que d’autres. Alors que le regard des historiens et historiennes s’est principalement focalisé sur les bourses « Autour du monde » du banquier Albert Kahn, les bourses de la fondation Rockefeller, ou encore celles de la Fédération internationale des femmes diplômées des Universités, d’autres programmes comme les bourses David‑W...

Here the philosopher and physicist David Z Albert argues, among other things, that the difference between past and future can be understood as a mechanical phenomenon of nature and that quantum mechanics makes it impossible to present the entirety of what can be said about the world as a narrative of “befores” and “afters.”.

Once upon a time, the twentieth-century investigations of the behaviors of sub-atomic particles were thought to have established that there can be no such thing as an objective, observer-independent, scientifically realist, empirically adequate picture of the physical world.

As early as 1784, sharp-eyed engineers and scientists noted striking similarities between the dynamics of seagoing vessels and aerial vehicles. By the early twentieth century, naval engineers and scientists were developing and designing airplanes and dirigibles using empirical principles derived from naval architecture. Several key researchers in aerodynamics began their career as naval architects (David A. Taylor, William F. Durand and Jerome C. Hunsaker) and carried out their experiments in ship testing facilities. By the 1930s, however, the transfer (...) of knowledge was irrevocably reversed as empiricism gave way to more fundamental, physics-based research. The rapid evolution of complex aircraft systems and flight envelopes led to new theoretical developments in aerodynamics and maneuvering, which quickly found their way into naval ship design. The theoretical and experimental results for airfoils, rigid airships and fixed-wing aircraft developed by Ludwig Prandtl, Theodore von Kármán, Max M. Munk and Hilda M. Lyon were employed in the hydrodynamic development of surface ships and submarines. This paper examines how the ideas, concepts and data from one discipline influenced the other and explores the processes by which that knowledge was transferred between disciplines. (shrink)

Presentists, who believe that only present objects exist, face a problem concerning truths about the past. Presentists should (but cannot) locate truth-makers for truths about the past. What can presentists say in response? We identify two rival factions ‘upstanding’ and ‘nefarious’ presentists. Upstanding presentists aim to meet the challenge, positing presently existing truth-makers for truths about the past; nefarious presentists aim to shirk their responsibilities, using the language of truth-maker theory but without paying any ontological price. We argue that presentists (...) should be nefarious presentists. (shrink)

David Bohm was one of the foremost scientific thinkers and philosophers of our time. Although deeply influenced by Einstein, he was also, more unusually for a scientist, inspired by mysticism. Indeed, in the 1970s and 1980s he made contact with both J. Krishnamurti and the Dalai Lama whose teachings helped shape his work. In both science and philosophy, Bohm's main concern was with understanding the nature of reality in general and of consciousness in particular. In this classic work he (...) develops a theory of quantum physics which treats the totality of existence as an unbroken whole. Writing clearly and without technical jargon, he makes complex ideas accessible to anyone interested in the nature of reality. (shrink)

It is argued that certain recent advances in the construction of a theory of the collapses of Quantum Mechanical wave functions suggest the possibility of new and improved foundations for statistical mechanics, foundations in which epistemic considerations play no role.

This book uncovers the lost history of Christianity's encounters with Pythagorean ideas before the Renaissance. David Albertson skillfully examines ancient and medieval theologians, particularly Thierry of Chartres and Nicholas of Cusa, who successfully reconceived the Trinity and the Incarnation within the framework of Greek number theory. David Albertson challenges modern assumptions about the complex relationship between religion and science.

This paper argues that higher-order doubt generates an epistemic dilemma. One has a higher-order doubt with regards to P insofar as one justifiably withholds belief as to what attitude towards P is justified. That is, one justifiably withholds belief as to whether one is justified in believing, disbelieving, or withholding belief in P. Using the resources provided by Richard Feldman’s recent discussion of how to respect one’s evidence, I argue that if one has a higher-order doubt with regards to P, (...) then one is not justified in having any attitude towards P. Otherwise put: No attitude towards the doubted proposition respects one’s higher-order doubt. I argue that the most promising response to this problem is to hold that when one has a higher-order doubt about P, the best one can do to respect such a doubt is to simply have no attitude towards P. Higher-order doubt is thus much more rationally corrosive than non-higher-order doubt, as it undermines the possibility of justifiably having any attitude towards the doubted proposition. (shrink)

David and Mary Norton present the definitive scholarly edition of Hume's Treatise, one of the greatest philosophical works ever written. This set comprises the two volumes of texts and editorial material, which are also available for purchase separately. David Hume is one of the greatest of philosophers. Today he probably ranks highest of all British philosophers in terms of influence and philosophical standing. His philosophical work ranges across morals, the mind, metaphysics, epistemology, religion, and aesthetics; he had broad (...) interests not only in philosophy as it is now conceived but in history, politics, economics, religion, and the arts. He was a master of English prose. The Clarendon Hume Edition will include all of his works except his History of England and minor historical writings. It is the only thorough critical edition, and will provide a far more extensive scholarly treatment than any previous editions. This edition offers authoritative annotation, bibliographical information, and indexes, and draws upon the major advances in textual scholarship that have been made since the publication of earlier editions - advances both in the understanding of editorial principle and practice and in knowledge of the history of Hume's own texts.

In his classic work, _Wholeness and the Implicate Order_, David Bohm develops a theory of quantum physics which treats the totality of existence, including matter and consciousness, as an unbroken whole. David Bohm presents a rational and scientific theory which explains cosmology and the nature of reality; written clearly, and without the use of technical jargon, it is essential reading for those interested in physics, philosophy, psychology and the connection between consciousness and matter. David Bohm was one (...) of the foremost scientific thinkers and distinguished theoretical physicists of his generation. His best-known works include: _Quantum Theory_,_Causality and Chance in Modern Physics_ and _The Undivided Universe_. (shrink)

David B. Wong proposes that there can be a plurality of true moralities, moralities that exist across different traditions and cultures, all of which address facets of the same problem: how we are to live well together. Wong examines a wide array of positions and texts within the Western canon as well as in Chinese philosophy, and draws on philosophy, psychology, evolutionary theory, history, and literature, to make a case for the importance of pluralism in moral life, and to (...) establish the virtues of acceptance and accommodation. Wong's point is that there is no single value or principle or ordering of values and principles that offers a uniquely true path for human living, but variations according to different contexts that carry within them a common core of human values. We should thus be modest about our own morality, learn from other approaches, and accommodate different practices in our pluralistic society. (shrink)

“What do you see when you look at your face in the mirror?” asks J. David Velleman in introducing his philosophical theory of action. He takes this simple act of self-scrutiny as a model for the reflective reasoning of rational agents: our efforts to understand our existence and conduct are aided by our efforts to make it intelligible. Reflective reasoning, Velleman argues, constitutes practical reasoning. By applying this conception, Practical Reflection develops philosophical accounts of intention, free will, and the (...) foundation of morals. This new edition of Practical Reflection contains the original 1989 text along with a new introduction and is the latest entry in The David Hume Series of Philosophy and Cognitive Science Reissues, which keeps in print previously published indispensable works in the area of cognitive science.

We discuss two recent attempts two solve Schrodinger's cat paradox. One is the modal interpretation developed by Kochen, Healey, Dieks, and van Fraassen. It allows for an observable which pertains to a system to possess a value even when the system is not in an eigenstate of that observable. The other is a recent theory of the collapse of the wave function due to Ghirardi, Rimini, and Weber. It posits a dynamics which has the effect of collapsing the state of (...) macroscopic systems. We argue that the modal interpretation cannot account for non-accurate measurements and that both accounts have the consequence that in ordinary measurement situations the observables that ends up well defined are not quite the ones that we want to be well defined. (shrink)

In the _The Undivided Universe_, David Bohn and Basil Hiley present a radically different approach to quantum theory. They develop an interpretation of quantum mechanics which gives a clear, intuitive understanding of its meaning and in which there is a coherent notion of the reality of the universe without assuming a fundamental role for the human observer. With the aid of new concepts such as active information together with non-locality, they provide a comprehensive account of all the basic features (...) of quantum mechanics, including the relativistic domain and quantum field theory. It is shown that, with the new approach, paradoxical or unsatisfactory features associated with the standard approaches, such as the wave-particle duality and the collapse of the wave function, do not arise. Finally, the authors make new suggestions and indicate some areas in which one may expect quantum theory to break down in a way that will allow for a test. _The Undivided Universe_ is an important book especially because it provides a different overall world view which is neither mechanistic nor reductionist. This view will ultimately have radical implications not only in physics but also in our general approach to all areas of life. (shrink)

Contrary to what many philosophers believe, Calvinism neither makes the problem of evil worse nor is it obviously refuted by the presence of evil and suffering in our world. Or so most of the authors in this book claim. While Calvinism has enjoyed a resurgence in recent years amongst theologians and laypersons, many philosophers have yet to follow suit. The reason seems fairly clear: Calvinism, many think, cannot handle the problem of evil with the same kind of plausibility as other (...) more popular views of the nature of God and the nature of God's relationship with His creation. This book seeks to challenge that untested assumption. With clarity and rigor, this collection of essays seeks to fill a significant hole in the literature on the problem of evil. (shrink)

I distinguish between two conceptually different kinds of physical space: a space of ordinary material bodies, which is the space of points at which I could imaginably place the tip of my finger, or the center of a billiard-ball, and a space of elementary physical determinables, which is the smallest space of points such that stipulating what is happening at each one of those points, at every time, amounts to an exhaustive physical history of the universe. In all classical physical (...) theories, these two spaces happen to coincide – and what we mean by calling a theory “classical”, and all we mean by calling a theory “classical”, is precisely that these two spaces coincide. But once the distinction between these two spaces in on the table, it becomes clear that there is no logical or conceptual reason why they must coincide – and it turns out that a very simple way of pulling them apart from one another gives us quantum mechanics.

David Bloor's challenging new evaluation of Wittgenstein's account of rules and rule-following brings together the rare combination of philosophical and sociological viewpoints. Wittgenstein enigmatically claimed that the way we follow rules is an "institution" without ever explaining what he meant by this term. Wittgenstein's contribution to the debate has since been subject to sharply opposed interpretations by "collectivist" and "individualist" readings by philosophers; in the light of this controversy, Bloor argues convincingly for a collectivist, sociological understanding of Wittgenstein's later (...) work. Accessible and simply written, this book provides the first consistent sociological reading of Wittgenstein's work for many years. (shrink)

[David Papineau] This paper disputes the common assumption that the normativity of conceptual judgement poses a problem for naturalism. My overall strategy is to argue that norms of judgement derive from moral or personal values, particularly when such values are attached to the end of truth. While there are philosophical problems associated with both moral and personal values, they are not special to the realm of judgement, nor peculiar to naturalist philosophies. This approach to the normativity of judgement is (...) made possible by naturalist views of truth, that is, views which do not presuppose normativity in explaining truth. /// [Julia Tanney] This paper attempts to describe why it is not possible to account for normative phenomena in non-normative terms. It argues that Papineau's attempt to locate norms of judgement 'outside' content, grounded in an individual's desires or reasons, mislocates the normativity that is thought to resist appropriation within a 'world that conceives nature as the realm of law'. It agrees, however, that a theory of content that locates norms 'inside' content will not be forthcoming-at least if this is to require fashioning the norms that in some sense govern judgment or thought into individually necessary conditions for contentful states.

David Hume's Dialogues concerning Natural Religion, first published in 1779, is one of the most influential works in the philosophy of religion and the most artful instance of philosophical dialogue since the dialogues of Plato. It presents a fictional conversation between a sceptic, an orthodox Christian, and a Newtonian theist concerning evidence for the existence of an intelligent cause of nature based on observable features of the world. This new edition presents it together with several of Hume's other, shorter (...) writings about religion, and with brief selections from the work of Pierre Bayle, who influenced both Hume's views on religion and the dialectical style of the Dialogues. The volume is completed by an introduction which sets the Dialogues in its philosophical and historical contexts. (shrink)

Aron Gurwitsch’s theory of the structure and dynamics of consciousness has much to offer contemporary theorizing about consciousness and its basis in the embodied brain. On Gurwitsch’s account, as we develop it, the field of consciousness has a variable sized focus or "theme" of attention surrounded by a structured periphery of inattentional contents. As the field evolves, its contents change their status, sometimes smoothly, sometimes abruptly. Inner thoughts, a sense of one’s body, and the physical environment are dominant field contents. (...) These ideas can be linked with (and help unify) contemporary theories about the neural correlates of consciousness, inattention, the small world structure of the brain, meta-stable dynamics, embodied cognition, and predictive coding in the brain.

Actions that go 'beyond the call of duty' are a common though not commonplace part of everyday life - in heroism, self-sacrifice, mercy, volunteering, or simply in small deeds of generosity and consideration. Almost universally they enjoy a high and often unique esteem and significance, and are regarded as, somehow, peculiarly good. Yet it is not easy to explain how - for if duty exhausts the moral life there is no scope to praise supererogatory acts, and if the consequentialist is (...) right there are no grounds for awarding them a special status. However, despite the distinctiveness of supererogation and the difficulty of accounting for it, philosophers have paid surprisingly little attention to the concept, and until now no thorough and systematic treatment of it has been proposed. This is what David Heyd offers in this book. His study will stimulate philosophers to recognise the importance of this rather neglected topic, and to take a fresh critical look at their theories in the light of its singular importance.

In the Theaetetus, Plato looks afresh at a problem to which, he now realizes, he had earlier given an inadequate answer: the problem of the nature of knowledge. What Plato has to say on this question is of great interest and importance, not only to scholars of Plato, but also to philosophers with wholly contemporary interests. This book is a sustained philosophical analysis and critique of the Theaetetus. David Bostock provides a detailed examination of Plato's arguments and the issues (...) that they raise. He adjudicates on rival interpretations of the text, and looks at the relations between this and other works of Plato. The book does not presuppose any knowledge of Greek. (shrink)

Terry Eagleton is the foremost Marxist cultural theorist of our time. In the first book-length study of this highly influential figure, David Alderson provides detailed discussions of Eagleton's Marxism and his engagements with postmodernism, as well as an evaluation of his interventions in Irish Studies. Each of the chapters in this important intervention in current theoretical debates offers accessible contextualization of the key issues and provides detailed analyses of Eagleton's literary criticism. Alderson shows that the complex relations between nature, (...) culture and ideology, body, subjectivity and authority are at the heart of Eagleton's ethical and political concerns. He goes on to demonstrate that these relations inform the theorist's critical examinations of such literary works as Wuthering Heights and The Merchant of Venice, and his treatment of W.B. Yeats and Oscar Wilde. (shrink)

David Egan offers an original comparative study of Wittgenstein and Heidegger, identifying a similar concern with authenticity in their work. By examining their divergent ideas on how to exist and philosophize authentically, Egan demonstrates Wittgenstein and Heidegger's continued relevance to contemporary thought in a novel way.

Tom Beauchamp presents the definitive scholarly edition of two famous works by David Hume, both originally published in 1757. In A Dissertation on the Passions Hume sets out his original view of the nature and central role of passion and emotion. The Natural History of Religion is a landmark work in the study of religion as a natural phenomenon. Authoritative critical texts are accompanied by a full array of editorial matter.

[David Charles] Aristotle, it appears, sometimes identifies well-being with one activity, sometimes with several, including ethical virtue. I argue that this appearance is misleading. In the Nicomachean Ethics, intellectual contemplation is the central case of human well-being, but is not identical with it. Ethically virtuous activity is included in human well-being because it is an analogue of intellectual contemplation. This structure allows Aristotle to hold that while ethically virtuous activity is valuable in its own right, the best life available (...) for humans is centred around, but not wholly constituted by, intellectual contemplation. /// [Dominic Scott] In Nicomachean Ethics X 7-8, Aristotle distinguishes two kinds of eudaimonia, primary and secondary. The first corresponds to contemplation, the second to activity in accordance with moral virtue and practical reason. My task in this paper is to elucidate this distinction. Like Charles, I interpret it as one between paradigm and derivative cases; unlike him, I explain it in terms of similarity, not analogy. Furthermore, once the underlying nature of the distinction is understood, we can reconcile the claim that paradigm eudaimonia consists just in contemplation with a passage in the first book requiring eudaimonia to involve all intrinsic goods.

The devotion of a full article in the Paris Agreement to loss and damage was a major breakthrough for the world’s most vulnerable nations seeing to gain support for climate impacts beyond what can be adapted to. But how will loss and damage be paid for, and who will pay it? Will ethics be part of this decision? Here we ask what are the possible means of raising predictable and adequate levels of funding to address loss and damage? Utilizing a (...) framework developed by Marco Grasso, we argue that making the ethical connections between addressing climate impacts and finance mechanisms could significantly enhance their likelihood of being adopted. We briefly review insurance mechanisms and catastrophe bonds, and then move on to six “innovative finance” approaches to funding loss and damage. We utilize six criteria in assessing them: adequacy, predictability, technical feasibility, fairness, and indirect effects, and whether each has a clear link to loss and damage. Several mechanisms for gathering funds emerged as most promising. Three of the six financial mechanisms we reviewed to raise funding involved airline transport: clearly, there is a huge opportunity to tax this sector in one form or another, in recognition of airline emissions’ role in creating losses and damages in vulnerable nations from sea level rise, droughts, floods or hurricanes. Funding loss and damage response is a contentious issue that will get only more unwieldy if Parties’ conceptions of loss and damage are at odds: a common definition of loss and damage needs to be agreed upon under the UNFCCC. Most immediately, to meet any equity criteria, wealthy countries should do more to support the premiums of those who cannot afford insurance. (shrink)

It is inquired how much an observer can ascertain of the quantum state of a system of which he and his measuring apparatus form a part; how much, for example, observers like ourselves can ascertain of the quantum state of the Universe. It turns out that no practicable experiment (and: perhaps, no experiment whatever) can establish that that state is not the vacuum. Some of the implications of this curious result are discussed.
