Mendelssohn's disagreement with Kant's definition survived on a two-sided Folio sheet (Statsbibliothek zu Berlin, Preuss. Kulturbesitz:, Nachlass 162, D I.4.). The dispute relates to Kant's inaugural lecture in Königsberg (August 1770): "De mundi sensibilis atque intelligibilis forma et principiis". A copy was immediately delivered to Mendelssohn by Kant's and Mendelssohn's mutual disciple, Marcus Herz. From Herz's long letter-report we know of a four-hour long discussion concerning Mendelssohn's intention to contrast Kant's definition of 'Raum' and 'Zeit' with that by Leibniz. Apparently (...) Mendelssohn's objection was never concluded or in print, hence, the _Kritik der reinen Vernunft (1781) still retains the interpretation that Mendelssohn's contested in 1770. (shrink)

Ideas about heredity and evolution are undergoing a revolutionary change. New findings in molecular biology challenge the gene-centered version of Darwinian theory according to which adaptation occurs only through natural selection of chance DNA variations. In Evolution in Four Dimensions, Eva Jablonka and Marion Lamb argue that there is more to heredity than genes. They trace four "dimensions" in evolution -- four inheritance systems that play a role in evolution: genetic, epigenetic, behavioral, and symbolic. These systems, they argue, can all (...) provide variations on which natural selection can act. Evolution in Four Dimensions offers a richer, more complex view of evolution than the gene-based, one-dimensional view held by many today. The new synthesis advanced by Jablonka and Lamb makes clear that induced and acquired changes also play a role in evolution.After discussing each of the four inheritance systems in detail, Jablonka and Lamb "put Humpty Dumpty together again" by showing how all of these systems interact. They consider how each may have originated and guided evolutionary history and they discuss the social and philosophical implications of the four-dimensional view of evolution. Each chapter ends with a dialogue in which the authors engage the contrarieties of the fictional "I.M.," or Ifcha Mistabra -- Aramaic for "the opposite conjecture" -- refining their arguments against I.M.'s vigorous counterarguments. The lucid and accessible text is accompanied by artist-physician Anna Zeligowski's lively drawings, which humorously and effectively illustrate the authors' points. (shrink)

'...a challenging and useful book, both because it provokes a careful scrutiny of one's own basic ideas regarding evolutionary theory, and because it cuts across so many biological disciplines.' -The Quarterly Review of Biology 'In my view, this work exemplifies Theoretical Biology at its best...here is rampant speculation that is consistently based on cautious reasoning from the available data. Even more refreshing is the absence of sloganeering, grandstanding, and 'isms'.' -Biology and Philosophy 'Epigenetics is fundamental to understanding both development and (...) gene expression, and not surprisingly, evolutionary biologists have long been fascinated with its proper place in evolutionary theory...Enter Jablonka and Lamb, who provide a thoughtful review of the recent molecular literature and suggest a number of potential consequences.' -EvolutionSince first publication of this controversial book, much of the initial opposition to the ideas it contained has been replaced by a general, although often grudging, acceptance of them. Advances in knowledge, especially at the molecular level, have enhanced general awareness and interest in epigenetics and the evolution of systems that store and transmit information and put any of the authors' speculations on a more solid basis. This paperback edition contains a new Preface that sets out the major changes in the scientific world and in the authors' own thinking that have occurred since the book was published. A new Appendix provides a selected bibliography of the many books and articles about epigenetic inheritance and its role in evolution that have appeared since first publication. (shrink)

For nearly two centuries, developmental biologists have known that body organs are derived from distinct germ layers. They have argued that adult stem cells formed in one of these, mesoderm for example, cannot give rise to cells that originate in another. We disagree. An exception to this “rule” has been described in crayfish recently. In this species, hemocytes appear to replenish neurogenic cells. This may happen in humans as well. In women who were given male bone marrow‐derived cells, Y chromosome (...) positive cheek cells and brain neurons were detected. While repopulation of these tissues by bone marrow derived cells may not occur normally, and while it does not appear to be terribly efficient, the phenomenon should be studied in more detail. Perhaps cells in the marrow could be used to regenerate tissues elsewhere. (shrink)

The attitude of biologists to the history of their discipline varies. For some, a hazy knowledge of the recent past is all that is necessary to provide an explanatory basis for their work. They take it for granted that everything of value from the less recent past has been appropriately incorporated into present-day thinking. Other biologists see history as an integral part of their research: the historical roots of accepted facts and theories help in the evaluation of present positions. These (...) biologists bring to history their specialized knowledge, which can be an advantage, but often they also bring an agenda that biases what they investigate and how they present it. We illustrate this by describing our own foray into history, which was motivated by findings in cell biology that suggested that some accepted views about heredity and evolution were wrong. (shrink)

Current knowledge of the genetic, epigenetic, behavioural and symbolic systems of inheritance requires a revision and extension of the mid-twentieth-century, gene-based, 'Modern Synthesis' version of Darwinian evolutionary theory. We present the case for this by first outlining the history that led to the neo-Darwinian view of evolution. In the second section we describe and compare different types of inheritance, and in the third discuss the implications of a broad view of heredity for various aspects of evolutionary theory. We end with (...) an examination of the philosophical and conceptual ramifications of evolutionary thinking that incorporates multiple inheritance systems. (shrink)

It is important to understand the processes behind how and why individuals emerge as leaders, so that the best and most capable individuals may occupy leadership positions. So far, most literature in this area has focused on individual characteristics, such as personality or cognitive ability. While interactions between individuals and context do get research attention, we still lack a comprehensive understanding of how the social context at work may help individuals to emerge as leaders. Such knowledge could make an important (...) contribution toward getting the most capable, rather than the most dominant or narcissistic individuals, into leadership positions. In the present work, we contribute toward closing this gap by testing a mediation chain linking a leader's leader self-awareness to a follower's leadership emergence with two time-lagged studies (nstudy1 = 449, nstudy2 = 355). We found that the leader's leader self-awareness was positively related to (a) the follower's leadership emergence and (b) the follower's nomination for promotion and that both relationships were serially mediated by the follower's self-leadership and the follower's leader self-efficacy. We critically discuss our findings and provide ideas for future research. (shrink)

Cognitive science is experiencing a pragmatic turn away from the traditional representation-centered framework toward a view that focuses on understanding cognition as "enactive." This enactive view holds that cognition does not produce models of the world but rather subserves action as it is grounded in sensorimotor skills. In this volume, experts from cognitive science, neuroscience, psychology, robotics, and philosophy of mind assess the foundations and implications of a novel action-oriented view of cognition. Their contributions and supporting experimental evidence show that (...) an enactive approach to cognitive science enables strong conceptual advances, and the chapters explore key concepts for this new model of cognition. The contributors discuss the implications of an enactive approach for cognitive development; action-oriented models of cognitive processing; action-oriented understandings of consciousness and experience; and the accompanying paradigm shifts in the fields of philosophy, brain science, robotics, and psychology.

In his theory of evolution, Darwin recognized that the conditions of life play a role in the generation of hereditary variations, as well as in their selection. However, as evolutionary theory was developed further, heredity became identified with genetics, and variation was seen in terms of combinations of randomly generated gene mutations. We argue that this view is now changing, because it is clear that a notion of hereditary variation that is based solely on randomly varying genes that are unaffected (...) by developmental conditions is an inadequate basis for evolutionary theories. Such a view not only fails to provide satisfying explanations of many evolutionary phenomena, it also makes assumptions that are not consistent with the data that are emerging from disciplines ranging from molecular biology to cultural studies. These data show that the genome is far more responsive to the environment than previously thought, and that not all transmissible variation is underlain by genetic differences. In Evolution in Four Dimensions (2005) we identify four types of inheritance (genetic, epigenetic, behavioral, and symbol-based), each of which can provide variations on which natural selection will act. Some of these variations arise in response to developmental conditions, so there are Lamarckian aspects to evolution. We argue that a better insight into evolutionary processes will result from recognizing that transmitted variations that are not based on DNA differences have played a role. This is particularly true for understanding the evolution of human behavior, where all four dimensions of heredity have been important. (shrink)

Animal and human studies suggest that parenting style is transmitted from one generation to the next. The hypotheses of this study were that a mother’s rearing experiences would predict her own parenting resources and current maternal mood, motivation to care for her offspring, and relationship with her parents would underlie this association. In a subsample of 201 first-time mothers participating in the longitudinal Maternal Adversity, Vulnerability and Neurodevelopment project, we assessed a mother’s own childhood maltreatment and rearing experiences using the (...) Childhood Trauma Questionnaire and the Parental Bonding Instrument. At 6 months postpartum, mothers completed questionnaires on parenting stress, symptoms of depression, maternal motivation, and current relationship with their own parents. The sample consisted of mostly high socioeconomic status mothers recruited from Montréal or Hamilton, Canada, with an age range from 18 to 43 years. More severe maltreatment and less supportive rearing by the mother’s parents predicted increased parenting stress at 6 months. These associations were mediated through distinct psychosocial pathways: maltreatment on parenting stress through symptoms of depression ; maternal rearing on parenting stress through maternal motivation and symptoms of depression ; and paternal rearing on parenting stress through current relationship with the father. Maternal rearing experiences predict a mother’s own parenting resources though distinct psychosocial pathways, including depressed mood, maternal motivation, and social support. (shrink)

THEN GO TO YOUR WORK WITH JOY - SOCIALITY AND SACRAMENTAILITY IN MARTIN LUTHER'S TEACHING OF THE CALLINGThe article investigates Martin Luther’s teaching of the calling in a social perspective. In the tradition following the pioneering work of Max Weber, the Reformation has often been interpreted a steppingstone towards processes of disenchantment, secularization and rationalization. In recent years, a growing body of literature has argued that this tradition overlooks crucial elements of reformation spirituality such as sacramentality, sociality and the affirmation (...) of ordinary life. With his conceptualization of work as a calling, Luther elevated and sanctified the everyday life and activities as a central component of the Christian life and the constitution of society. Here we might find the seed for the exceptionally high value ascribed to work in contemporary, Lutheran Nordic societies. (shrink)

In responding to three reviews of Evolution in Four Dimensions (Jablonka and Lamb, 2005, MIT Press), we briefly consider the historical background to the present genecentred view of evolution, especially the way in which Weismann’s theories have influenced it, and discuss the origins of the notion of epigenetic inheritance. We reaffirm our belief that all types of hereditary information—genetic, epigenetic, behavioural and cultural—have contributed to evolutionary change, and outline recent evidence, mainly from epigenetic studies, that suggests that non-DNA heritable variations (...) are not rare and can be quite stable. We describe ways in which such variations may have influenced evolution. The approach we take leads to broader definitions of terms such as ‘units of heredity’, ‘units of evolution’, and ‘units of selection’, and we maintain that ‘information’ can be a useful concept if it is defined in terms of its effects on the receiver. Although we agree that evolutionary theory is not undergoing a Kuhnian revolution, the incorporation of new data and ideas about hereditary variation, and about the role of development in generating it, is leading to a version of Darwinism that is very different from the gene-centred one that dominated evolutionary thinking in the second half of the twentieth century.

According to a mainstream position in contemporary cognitive science and philosophy, the use of abstract compositional concepts is amongst the most characteristic indicators of meaningful deliberative thought in an organism or agent. In this article, we show how the ability to develop and utilise abstract conceptual structures can be achieved by a particular kind of learning agent. More specifically, we provide and motivate a concrete operational definition of what it means for these agents to be in possession of abstract concepts, (...) before presenting an explicit example of a minimal architecture that supports this capability. We then proceed to demonstrate how the existence of abstract conceptual structures can be operationally useful in the process of employing previously acquired knowledge in the face of new experiences, thereby vindicating the natural conjecture that the cognitive functions of abstraction and generalisation are closely related.

Die Entscheidung für oder gegen lebensverlängernde Behandlungsmaßnahmen geht inzwischen der Hälfte aller Todesfälle in Europa voraus. Sie wird im klinischen Alltag häufig als ethische Herausforderung wahrgenommen, zudem sind unter Klinikern juristische Unsicherheiten und Fragen der korrekten Vorgehensweise verbreitet. Die hier vorgestellte Münchner Leitlinie zu Entscheidungen am Lebensende soll rechtliche Unsicherheit reduzieren, Klinikumsmitarbeiter für die ethische Dimension von Therapieentscheidungen am Lebensende sensibilisieren und ethisch begründete Entscheidungen fördern. Aus organisationsethischer Perspektive soll mit der Leitlinie eine Reflexion und Meinungsbildung zu einem ethisch relevanten (...) Themenbereich erfolgen und ein Beitrag zur Qualitätssicherung der Patientenversorgung und damit auch zur Patientenzufriedenheit geleistet werden. Die Prozesse der Leitlinienentwicklung, -aktualisierung und -implementierung werden vorgestellt. Die wesentlichen inhaltlichen Elemente der Leitlinie mit Darstellung der Rechtslage, der Definition zentraler Begriffe und Klärung medizinischer Entscheidungskriterien werden an Hand eines Entscheidungsalgorithmus dargestellt. Inhalt und Prozess der Leitlinienentwicklung werden auf die folgenden organisationsethischen Qualitätskriterien hin überprüft: deliberativer Prozess, inhaltliche Transparenz, repräsentative Zusammensetzung der Arbeitsgruppe, Implementierung und Evaluation der Leitlinie. Institutionen, die diese Leitlinie übernehmen wollen, sollten diese von einem autorisierten Gremium überprüfen lassen und auf die spezifischen Bedürfnisse ihrer Institution adaptieren. Hierfür ist eine vorgeschaltete Bedarfserhebung hilfreich. In dem Gremium sollten all diejenigen vertreten sein, die in der Folge mit der Leitlinie arbeiten werden. (shrink)

Adaptive evolution is usually assumed to be directed by selective processes, development by instructive processes; evolution involves random genetic changes, development involves induced epigenetic changes. However, these distinctions are no longer unequivocal. Selection of genetic changes is a normal part of development in some organisms, and through the epigenetic system external factors can induce selectable heritable variations. Incorporating the effects of instructive processes into evolutionary thinking alters ideas about the way environmental changes lead to evolutionary change, and about the interplay (...) between genetic and epigenetic systems.

The commentaries on Evolution in Four Dimensions reflect views ranging from total adherence to gene-centered neo-Darwinism, to the acceptance of non-genetic and Lamarckian processes in evolution. We maintain that genetic, epigenetic, behavioral, and cultural variations have all been significant, and that the developmental aspects of heredity and evolution are an important bridge that can unite seemingly conflicting research programs and different disciplines.

The fundamental mechanisms of protein and lipid organization at the plasma membrane have continued to engage researchers for decades. Among proposed models, one idea has been particularly successful which assumes that sterol‐dependent nanoscopic phases of different lipid chain order compartmentalize proteins, thereby modulating protein functionality. This model of membrane rafts has sustainably sparked the fields of membrane biophysics and biology, and shifted membrane lipids into the spotlight of research; by now, rafts have become an integral part of our terminology to (...) describe a variety of cell biological processes. But is the evidence clear enough to continue supporting a theoretical concept which has resisted direct proof by observation for nearly twenty years? In this essay, we revisit findings that gave rise to and substantiated the raft hypothesis, discuss its impact on recent studies, and present alternative mechanisms to account for plasma membrane heterogeneity.
