This collection offers a critical assessment of the published works of Piero Sraffa, one of the leading economists of the twentieth century, and their legacy for the economics profession. The topics covered explore Sraffa's interpretation of the classical economists; his theory of value and distribution; his critique of partial and general neoclassical equilibrium theory; his focus on the problem of capital; and his critique of Hayek's monetary overinvestment theory of the business cycle. Specific issues investigated include intertemporal general equilibrium theory (...) and the capital problem; the probability of reswitching; Ricardo, Malthus, and the corn model; and the meaning and implication of the capital controversy. Among the contributors are many of the world's leading students of Sraffian economics, including Nobel Laureate Paul Samuelson, Christian Bidard, Edwin Burmeister, John Eatwell, Pierangelo Garegnani, Samuel Hollander, Heinz Kurz, Lynn Mainwaring, Neri Salvadori, Bertram Schefold and Ian Steedman.

The last kilometers of the Berlin Wall were finally torn down during this last week before Christmas, but mentally, socially, economically it continues to exist, and for some in what used to be East Berlin it isn’t so clear anymore whether the actual wall made of concrete wasn’t easier to bear. To be sure, the wall that once separated the largest cities in each of the two Germanys is still present as a scar of empty space; but distances have shrunk, (...) and old views of the city have been reestablished—at least geographically, Berlin, no doubt, is slowly becoming one again. However, the social and economic differences as well as the mental walls erected in forty years of separate existence still divide the eastern from the western part. Now that the euphoria of unification has finally subsided, gains and losses are being counted, and many East Germans are beginning to ask themselves whether the price they paid for political freedom was not too high after all. The moral and economic bankruptcy of the old regime daily becomes more apparent: its structures of corruption and repression, its system of total surveillance that had become a part of everyday life and made use of even those whom the state had marginalized. And yet that system, corrupt as it was, had also provided a measure of stability, a predictable life that, although it had restricted individual choice, can now evoke nostalgic memories of warmth and security. Heinz Ickstadt is professor of American literature at the John F. Kennedy Institute for North American Studies at the Free University in Berlin. He has written and edited books on Hart Crane, Thomas Pynchon, and the 1930s, and has published widely on American literature and culture in the late nineteenth century, American modernism, postmodern fiction, and on the relation of literature and painting. A book on the changing functions of the American novel, coauthored with Winfried Fluck, is forthcoming. (shrink)

Previously published as special issues of _The European Journal of the History of Economic Thought_ and _The Review of Political Economy_, this volume contains the papers devoted to the life and work of Piero Sraffa. Sraffa was a leading intellectual of the twentieth century. He was brought to Cambridge by John Maynard Keynes and had an important impact on the philosopher Ludwig Wittgenstein. He received the golden medal Söderström of the Swedish Academy of Sciences for his edition of David Ricardo's (...) _Works and Correspondence_ and he is the author of _Production of Commodities by Means of Commodities_, one of the most often cited book in economics. Using hitherto unpublished material from Sraffa's literary heritage kept at Trinity College, Cambridge, the papers throw new light on the intellectual development of the young Sraffa and correct several of the received views on him and his contribution. Themes covered concern his: objectivism rediscovery and reformulation of the classical theory of value and distribution criticism of Alfred Marshall's analysis relationship with his Cambridge colleagues and friends biography around the time when he left Italy for the UK friendship with Wittgenstein and his impact on the latter's thinking.

The paper tries to contribute to the discussion of the following problem: Nearly every government acts as if it has a natural right to collect taxes – if necessary by force. How legitimate is such an act of expropriation? To find an acceptable solution, three different theories of property are discussed – eventually favouring the Kantian approach. Subsequently, possible vindications of taxation are presented: (1) control of conduct, (2) financing public institutions, (3) reduction of social differences. All three justifications turn (...) out to be de ficient. What remains is John St. Mill's almost forgotten theory; he sees taxes as a sacrifice and, on this account, pleads for a proportional taxation. (shrink)

In _Conceptual Issues in Psychoanalysis_, John Gedo's mastery of Freudian theory and broad historical consciousness subserve a new goal: an understanding of "dissidence" in psychoanalysis. Gedo launches his inquiry by reflecting expansively on recent assessments of Freud's character. His acute remarks on the intellectual and personal agendas that inform the portraits of Freud offered by Frank Sulloway, Jeffrey Masson, and Peter Swales pave the way for his own definition of psychoanalysis in historical context. Then, in topical studies on Sandor Ferenczi, (...) Melanie Klein, and Heinz Kohut, he explicates the commonalities that bind together three generations of dissidents, each of whom undertook to supplant the edifice of hypotheses erected by Freud with alternative theories. Interspersed with these essays are quite insightful studies of Lou Andreas-Salome and David Rapaport, whom Gedo sees as "epistemological referees" attempting to reconcile viewpoints unique to their generations. In the second part of the book, Gedo argue that analysis now has the opportunity to move beyond this pattern of dissidence followed by mediation by drawing on observational research about infancy and early childhood to validate or refute its clinical hypotheses. In these chapters, Gedo offers critical commentary on recent efforts to extrapolate from infant research to the psychoanalytic theory of development. Only then does he offer his own measured estimation of the "legacy of infancy and the technique of psychoanalysis." This review of "the challenge of scientific method" as it bears on analysis culminates in concluding chapters that probe the status of analysis as a hermeneutic discipline and the contribution of analysis to "vocabularies of moral deliberation.".

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 23 (2003) 178-181 [Access article in PDF] Buddhist Perceptions of Jesus. Edited by Perry Schmidt-Leukel with Gerhard Koberlin and Thomas Josef Gotz, OSB. St. Ottilien: EOS-Verlag, 2001. 179 pp. The papers collected here represent a significant step forward in European scholarship on Buddhist-Christian relations. As Perry Schmidt-Leukel remarks in his helpful introduction, they are an experiment in correlating auto-interpretation and hetero-interpretation, introspection and extrospection.Each of the first (...) three sections—on China/Japan, Southeast Asia, and Europe—begins with a historical study. Iso Kern clears up some misconceptions about the Jesuits' approach to mission work in China, stating that they did in fact preach Jesus crucified (37) and the doctrine of Atonement (41) in the face of a grave danger that Christianity would simply be absorbed into Buddhism (33). Whereas Buddhism had no specifically religious clash with the state, Christianity did, and this was eventually sealed by martyrdom in both China and Japan. Introducing part 2, Heinz Murmel gives a sober reassessment of the vehement controversies between a certain segment of Buddhism and a certain type of Christianity in Ceylon. Only the high-caste highland nikayas were protected by the British (63); the more popular, rural Buddhists of the lowlands felt excluded and threatened and gave rise to what became known as "Protestant Buddhism." The "great debates" between bitterly anti-Christian monks and Protestant clergymen were not as important as the records may suggest, and even the fiery Anagarika Dharmapala later disclosed that he felt great devotion to Jesus. Finally, Frank Usarski reviews the heated debates between ill-informed Christians and overaggressive Buddhist converts such as Karl B. Seidenstucker as Buddhism established itself in Germany in the early decades of the twentieth century. The History of Religions school seemed to suggest that Christianity was culturally inferior to Buddhism, which was allegedly proved by Christian attitudes to [End Page 178] vegetarianism and the general anti-intellectualism of Christianity. Christianity was inauthentic, derivative, "Buddhism in Jewish garments" (120).Yet even Seidenstucker, the renegade Protestant, converted to Catholicism toward the end of his life.Each historical contribution is followed by an essay on the contemporary situation in the three regions, and these vary greatly in substance. Shizuteru Ueda offers a profound meditation on the significance of Keiji Nishitani for Buddhist approaches to Christianity. If Nietzsche posed the fundamental question of "life without why " (44-45), the thought of Meister Eckhart contains the answer (curiously, Ueda insists that this answer must be European, because Europe "determines the world" [47]). The "ground" on which we stand, interpreted as Nishida's "place (basho) of nothingness," is "ground-less." This is not nihilism but the overcoming of nihilism by nihilism, the shûnyatâ of shûnyatâ (46). Jesus as the Christ is the God/man and therefore the mediator, the absolute in history (53). He occupies the "place" (basho) of infinite openness, unconditioned ultimacy (55). He is thus unique, but not universal: the ultimate "for me" is not necessary "for the whole of mankind" (56). The actual encounter between Buddhist and Christian absolutes takes place in silence.Santikaro Bhikkhu, the friend and translator of Buddhadâsa Bhikkhu in the last eight years of his life, tells how his mentor gradually overcame his initial suspicion ofChristianity, perhaps because he was not confronted with colonial oppression as Dharmapala was in Ceylon. Distinguishing between "people language" and " dhamma language," he eventually arrived at a certain equivalence between the Christian God and Buddhist dhamma understood as a nonpersonal, nondual transcendent that is nevertheless not outside nature (85, 90). What Jesus the Teacher of Wisdom offers in the Sermon on the Mount, if practiced, is sufficient for salvation (93). In the perspective of dhamma language, however, the God of Christian convention is conditioned, and Jesus as Son of God cannot be unique. Though inconclusive and sometimes obscure because of Buddhadâsa's indifferent grasp of English, this is surely an astonishing journey for one who tried to understand each tradition, including his own, from the sources. It brought him fierce criticism from fellow Buddhists, however, who branded him a... (shrink)

The DAP (Death Associated Protein) kinase family is a novel subfamily of pro-apoptotic serine/threonine kinases. All five DAP kinase family members identified to date are ubiquitously expressed in various tissues and are capable of inducing apoptosis. The sequence homology of the five kinases is largely restricted to the N-terminal kinase domain. In contrast, the adjacent C-terminal regions are very diverse and link individual family members to specific signal transduction pathways. There is increasing evidence that DAP kinase family members are involved (...) in both extrinsic and intrinsic pathways of apoptosis and may play a role in tumor progression. This review will focus on structural composition and subcellular localization of DAP kinase family members and on signal transduction pathways leading to their activation. Potential mechanisms of DAP kinase family-mediated apoptosis will be discussed. BioEssays 23:352–358, 2001. © 2001 John Wiley & Sons, Inc. (shrink)

Die Frage nach dem Verhältnis Osteuropas zum Westen ist nicht nur aktueller denn je, sondern hat auch eine lange und ambivalente Geschichte. Diese hing jeweils stark von den Selbstwahrnehmungen der beteiligten Kulturen ab. Brücken bauen beschäftigt sich nicht nur mit den Selbst- und Fremdwahrnehmungen aus historischer, literaturwissenschaftlicher, philosophischer und politikwissenschaftlicher Sicht, sondern beleuchtet auch die Beziehungen zwischen West und Ost sowie gemeinsame ebenso wie jeweils eigene Phänomene und Strömungen. Mit den Beiträgen soll Leonid Luks, Direktor des Zentralinstitutes für Mittel- und (...) Osteuropastudien an der Katholischen Universität Eichstätt-Ingolstadt und einer der fleißigsten Brückenbauer zwischen Ost und West, zu seinem 65. Geburtstag geehrt werden. So spiegelt Brücken bauen Luks' eigene Forschungsschwerpunkte wider.

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 20 (2000) 257-259 [Access article in PDF] Jesus through Buddhist Eyes: 3rd Conference of European Network of Buddhist-Christian Studies, Archabbey St. Ottilien, Germany, February 26-March 1, 1999 John D'Arcy MayIrish School of Ecumenics, DublinThis ambitious conference, attended by well over 100 participants including a number of practitioners of Buddhist meditation from southern Germany and Austria, has put the European Network of Buddhist-Christian Studies firmly on its feet. (...) Intended mainly for academics working in the field and held entirely in English, the conference, on "Buddhist Perceptions of Jesus," traced various paths from the polemics which characterized relations between Buddhists and Christians well into the century now ending to the remarkable progress made by Buddhist-Christian dialogue in recent decades. The Archabbey of St. Ottilien has itself been the scene of intermonastic exchanges between the Benedictine monks and their Japanese Zen counterparts.The architecture of the conference brought out clearly the distance that has been traveled. Iso Kern (Berne) examined the missionary methodology of the Jesuits in sixteenth- and seventeenth-century China. He showed how they preferred to rely on arguments from reason rather than affront the Chinese with the full implications of Christian revelation, treading a thin line between absorption into harmony with Chinese religion as "a special type of Buddhism" and controversy about the uniqueness of Jesus and his redemptive death on the cross. The Christian idea of a Creator who redeems a sinful world by the substitutionary sacrifice of his own Son was so repugnant to Confucian sensibility that the Jesuits chose a different route, though Professor Kern defended them against Pascal's accusation that they 'hid' the scandal of the cross. Heinz Murmel (Leipzig, in a paper read in his absence) sketched the sterile polemics which characterized early Buddhist-Christian encounters in Ceylon/Sri Lanka, while Frank Usarski (São Paulo) analyzed the equally bitter exchanges between early German converts to Buddhism and their Christian opponents. We were to find not only that these controversies are still remembered in Southeast Asia, but that the obstacles to understanding encountered by the Jesuits in China and Japan still cause problems in Buddhist-Christian relations today. [End Page 257]Of fundamental importance to the development of the conference was a difficult paper by Shizuteru Ueda (Kyoto) on "Jesus in Contemporary Japanese Zen." Starting with his teacher Nishitani's presentation on "Nietzsche and Eckhart" to Heidegger's seminar in 1938, Professor Ueda set out to show how both European nihilism and Christian absolutism can be overcome by Nishitani's understanding of s´unyata: "The last ground of 'I am‚' is without ground and groundless." S´unyata is itself subject to s´unyata: nihilism can only be surmounted through nihilism itself. This dynamic relationship between Into-Nothingness and Out-of-Nothingness is Zen's point of access to Paul's characterization of Christian life-out-of death: "I live no more, Christ lives in me" (Gal. 2:20). Confronted by the question "Who said this?" as Nishitani confronted his Christian friend Muto, the Christian is challenged to ask whether he or she can actually say it, thereby bearing true witness. Ueda's problem is not with this witness, but with the Christian claim that Jesus is unique, for God is not only infinite Person but infinite Openness (basho).Some of these themes were echoed by two speakers who based themselves on experience rather than philosophy: Karl Schmied, a lay associate of Thich Nhat Hanh, and Than Santikharo Bhikkhu, an American monk at Suan Mokkh and Buddhadasa's translator in the last eight years of his life. Without repudiating his Catholic roots, Schmied said that he had simply found more joy in Buddhism. If Jesus is Son of Man and Son of God non-dualistically, could not the relationship between Buddhism and Christianity be one of non-duality, despite obvious differences (rebirth/ historical uniqueness; no-self/person; emptiness/being). Cannot Jesus be seen as a universal Bodhisattva whose 'center,' is everywhere rather than as God's 'only' son?Santikharo Bhikkhu, who still visits... (shrink)

The editing of the correspondence of major figures in intellectual history is an essential scholarly activity. Yet in this country in recent years it has neither been the priority it should be, nor has it received the support that it deserves. Of course there have been exceptions to this, perhaps notably – for the early modern period – the epic one-man effort of Esmond de Beer in his later years in producing The Correspondence of John Locke (though this regrettably, and (...) frustratingly, lacks a composite index). A further exception, the edition of The Correspondence of Henry Oldenburg by A. R. and M. B. Hall, was unfortunately flawed by the need to change publishers midway in the series, which has led to a marked disparity in the availability of the latter part of the set compared with its early volumes. In any case, like the Locke edition, this was conceived in the heady days of the 1960s and early 1970s, and few have ventured such enterprises since. Virtually the only exception is Noel Malcolm's edition of the manageable-sized Correspondence of Thomas Hobbes (two volumes, 1994). Moreover, it is revealing of the acute need to justify the publication of such material felt by editors and publishers alike that the promotional leaflet for this edition went so far as to claim that it was ‘one of the most important scholarly publications of the twentieth century’ – a claim that is the more ironic in view of the quite significant shortcomings in its method of presenting the material that it contains.

Everyday media consumption leaves no doubt that the perception of moving images from various media is characterized by experience and understanding. Corresponding research in this field has shown that the stimulus patterns flooding in on us are not only processed mentally, but also bodily. Building on this, the following study argues that incoming stimuli are processed not only visually, but multimodally, with all senses, and moreover affectively. The classical binding of a sensory organ to a medium, on whose delimitation the (...) common understanding of multimodality is based, is thus abolished. Can arguments for this assumption be found? Building on the research of cultural anthropologist Ernst Cassirer and his successors, the two American philosophers Susanne K. Langer and John M. Krois, and supported by research from the life sciences in which, in parallel, the arts also play an important role in understanding image formation, as in the work of Heinz Werner and, following on from this, in the more recent research of the child psychologist Daniel N. Stern in collaboration with mirror neuron research by the group of neuroscientists around Giacomo Rizzolatti in Parma, justifications for this will be provided. What the multimodal processing of film images is concretely based on will finally be made clear by means of an exemplary analysis of a video film by the Swiss artist Pipilotti Rist. It aims to prove, that the prerequisites for the thesis can only lie in the fact, that both the modes of perception (visual, tactile, auditory, olfactory, gustatory) as well as the medially conditioned modes of image formation are based on non-discursive, formal-abstract structures that are also processed affectively. At the same time, the analysis thus shows how the selection and composition of the vital experienced forms can provide information about the socio-culturally shaped self-image of the producer and the viewer.

An important distinction between phonology and syntax has been overlooked. All phonological patterns belong to the regular region of the Chomsky Hierarchy, but not all syntactic patterns do. We argue that the hypothesis that humans employ distinct learning mechanisms for phonology and syntax currently offers the best explanation for this difference.

This compelling book contains a comprehensive analytical treatment of the theory of production in a long-period framework. Although the authors take a 'Classical' approach to their subject, the scope of investigation and methods employed should interest all economic theorists. Professors Kurz and Salvadori explore economic systems that are characterised by a particular kind of primary input in the production process, such as different kinds of labour and natural resources. These systems and the corresponding prices can be understood to reflect characteristic (...) features of a capitalist market economy in an ideal way: they express the pure logic of the relationship between value and distribution in an economic system. Specific chapters deal with prices and income distribution, economic growth, joint production, fixed capital, scarce natural resources, and heterogeneous labour. The historical origins of the concepts used are also discussed in considerable detail. (shrink)

The present work critically examines two assumptions frequently stated by supporters of cognitive neuroenhancement. The first, explicitly methodological, assumption is the supposition of effective and side effect-free neuroenhancers. However, there is an evidence-based concern that the most promising drugs currently used for cognitive enhancement can be addictive. Furthermore, this work describes why the neuronal correlates of key cognitive concepts, such as learning and memory, are so deeply connected with mechanisms implicated in the development and maintenance of addictive behaviour so that (...) modification of these systems may inevitably run the risk of addiction to the enhancing drugs. Such a potential risk of addiction could only be falsified by in-depth empirical research. The second, implicit, assumption is that research on neuroenhancement does not pose a serious moral problem. However, the potential for addiction, along with arguments related to research ethics and the potential social impact of neuroenhancement, could invalidate this assumption. It is suggested that ethical evaluation needs to consider the empirical data as well as the question of whether and how such empirical knowledge can be obtained. (shrink)
