Heredity has been dismissed as an insignificant object in Claude Bernard’s physiology, and the topic is usually ignored by historians. Yet, thirty years ago, Jean Gayon demonstrated that Bernard did elaborate on the subject. The present paper aims at reassessing the issue of heredity in Claude Bernard’s project of a “general physiology”. My first claim is that Bernard’s interest in heredity was linked to his ambitious goal of redefining general physiology in relation to morphology. In 1867, not (...) only was morphology included within experimental physiology, but it also theoretically grounded physiological investigations. By 1878, morphology and physiology were considered as completely independent sciences, and only the latter was perceived as suitable to experimentation. My second claim is that this reversal reflected the existence of two opposite attitudes towards heredity. In the late 1860s, Bernard was convinced that heredity would soon be accessible to experimental manipulation and that new species would be produced in the laboratory exactly like organic chemistry succeeded to do for raw bodies. Ten years later, he ascertained that this was impossible. My third claim is that Bernard was epistemologically ill-equipped to address the issue of heredity. Bernard was strongly committed to a general reasoning scheme that acknowledged only three categories: determining conditions, constant laws and phenomena. This scheme was a key factor in his successes as a physiologist who was able to capture new mechanisms in living bodies. Nonetheless, it also prevented him from understanding how time and history could be endowed with a causal action that cannot be reduced to timeless parameters. (shrink)

TheConstitution of Manby George Combe (1828) was probably the most influential phrenological work of the nineteenth century. It not only offered an exposition of the phrenological theory of the mind, but also presented Combe's vision of universal human progress through the inheritance of acquired mental attributes. In the decades before the publication of Darwin'sOrigin of Species, theConstitutionwas probably the single most important vehicle for the dissemination of naturalistic progressivism in the English-speaking world. Although there is a significant literature on the (...) social and cultural context of phrenology, the role of heredity in Combe's thought has been less thoroughly explored, although both John van Wyhe and Victor L. Hilts have linked Combe's views on heredity with the transformist theories of Jean-Baptiste Lamarck. In this paper I examine the origin, nature and significance of his ideas and argue that Combe's hereditarianism was not directly related to Lamarckian transformism but formed part of a wider discourse on heredity in the early nineteenth century.

This book places under sustained scrutiny some of our most basic modern assumptions about inheritance, genealogy, blood relations, and racial categories. It has at its core a deceptively simple question, one too often taken for granted: what constitutes "good" bonds among humans, and what compels us to determine them so across generations as both a physical and a metaphysical attribute? Answering this question is complex and involves a foray into a seemingly disparate array of early modern sources: from adages, common (...) law, and literature about bloodlines and bastardy to philosophical, political, and scientific discourses that both confirm and confound the "common sense" of familial, communal, national, and racial identity.  .

This paper aims to give an impression of how biologists, at the turn of the twentieth century, came to conceptualize and define the hidden entities presumed to govern the process of hereditary transmission. With that, the stage was set for the emergence of genetics as a biological discipline that came to dominate the life sciences of the twentieth century. The annus mirabilis of 1900, with its triple re-appreciation of Gregor Mendel’s work by the botanists Hugo de Vries, Carl Correns, and (...) Erich Tschermak, can be seen as the watershed after which theorizing about heredity and experimentation—selecting pure lines and Mendelian crossing—became tightly connected. As to concepts before this, this paper will analyze Carl von Nägeli’s ‘idioplasm’, Hugo de Vries’s ‘pangenes’, and August Weismann’s ‘germ plasm’. Carl Correns’s Anlagen and Wilhelm Johannsen’s ‘genes’ would replace them in the decade after 1900.Keywords: Idioplasm ; Pangenes ; Germ plasm ; Anlagen ; Gene; Genotype. (shrink)

This article explores the collaborative research of the Nobel laureate Hans Spemann (1869–1941) and the Swiss zoologist Fritz Baltzer (1884–1974) on problems at the intersection of development and heredity and raises more general questions concerning science and politics in Germany in the interwar period. It argues that Spemann and Baltzer’s collaborative work made a significant contribution to the then ongoing debates about the relation between developmental physiology and hereditary studies, although Spemann distanced himself from _Drosophila_ genetics because of his (...) anti-reductionist position. The article analyzes how Spemann framed the issues of heredity in terms of an epigenetic principle in the context of his work on the “organizer,” and it explores the experimental dynamics of research on newt merogones carried out by Baltzer in a methodological development of Spemann’s constriction experiments. Finally, these research attempts are discussed as part of a broader “prehistory” of the mid-twentieth century cell nuclear transplantation experiments, which provided the basis for later animal cloning.

Historians have emphasized the appearance of a productive research program in genetics after 1910, and philosophers and biologists have considered endorsement of genetics as a progressive move, indeed as a starting point for modern experimental biology. These efforts focus on what biology had changed to. This paper examines the condition from which biology moved, stressing the way in which Americans held heredity and development as a natural, intimately intertwined couple. Heredity accounts for likenesses, development for variation, and the (...) two act together throughout an individual's life. This discussion establishes the antecedent conditions necessary to explain the split of genetics and embryology and addresses the reasons for the split. (shrink)

The exploration of the mechanisms of cultural heredity has often been regarded as the key to explicating human uniqueness. Particularly early imitative learning, which is explained as a kind of simulation that rests on the infant’s identification with other persons as intentional agents, has been stressed as the foundation of cumulative cultural transmission. But the question of what are the objects of this mechanism has not been given much attention. Although this is a pivotal point, it still remains obscure. (...) I will characterize the notion of action-types and show why they are the genuine objects of cultural heredity. However, this answer is in conflict with the concept of imitation, and the problem arises that, if imitation is conceptualized as simulation and explained in terms of the cognition of infants, the objects of cultural transmission seemingly cannot be passed on by imitation. In order to solve this problem, I propose reconsidering the concept of imitation and to conceptualize imitation as a cooperative activity of infants and adults. (shrink)

Darwin's ideas on variation, heredity, and development differ significantly from twentieth-century views. First, Darwin held that environmental changes, acting either on the reproductive organs or the body, were necessary to generate variation. Second, heredity was a developmental, not a transmissional, process; variation was a change in the developmental process of change. An analysis of Darwin's elaboration and modification of these two positions from his early notebooks (1836-1844) to the last edition of the /Variation of Animals and Plants Under (...) Domestication/ (1875) complements previous Darwin scholarship on these issues. Included in this analysis is a description of the way Darwin employed the distinction between transmission and development, as well as the conceptual relationship he saw between heredity and variation. This paper is part of a larger project comparing commitments regarding variation during the latter half of the nineteenth century. (shrink)

The so-called “Baldwin Effect” has been studied for years in the fields of Artificial Life, Cognitive Science, and Evolutionary Theory across disciplines. This idea is often conflated with genetic assimilation, and has raised controversy in trans-disciplinary scientific discourse due to the many interpretations it has. This paper revisits the “Baldwin Effect” in Baldwin’s original spirit from a joint historical, theoretical and experimental approach. Social Heredity – the inheritance of cultural knowledge via non-genetic means in Baldwin’s term – is also (...) taken into consideration. I shall argue that the Baldwin Effect can occur via social heredity without necessity for genetic assimilation. Computational experiments are carried out to show that when social heredity is permitted with high fidelity, there is no need for the assimilation of acquired characteristics; instead the Baldwin Effect occurs as promoting more plasticity to facilitate future intelligence. The role of mind and intelligence in evolution and its implications in an extended synthesis of evolution are briefly discussed. (shrink)

We develop a conceptual framework that connects biological heredity and organization. We refer to heredity as the cross-generation conservation of functional elements, defined as constraints subject to organizational closure. While hereditary objects are functional constituents of biological systems, any other entity that is stable across generations—and possibly involved in the recurrence of phenotypes—belongs to their environment. The central outcome of the organizational perspective consists in extending the scope of heredity beyond the genetic domain without merging it with (...) the broad category of cross-generation stability. After discussing some implications, we conclude with a reflection on the relationship between stability and variation. 1Introduction2From Extended Heredity to Cross-generation Stability 2.1Extending the scope of heredity: A brief state of the art2.2Rethinking heredity: Conceptual challenges3Biological Heredity in Light of Organization 3.1Biological organization within organisms and beyond3.2Extending organization in time3.3What is biological heredity?4Implications and Objections 4.1Heredity as a specific kind of cross-generation stability4.2Heredity at various levels of description4.3Non-functional and dysfunctional objects5Conclusions: From Conservation to Variation.

This commentary acknowledges the importance of Davey's biocognitive approach to the uneven distribution of fears on the basis of its contribution to a human model for understanding fear. An integrated heredity-environment and developmental transactional approach based on field/system theory is recommended in place of the mechanistic heredity × environment interactionism that Davey uses to explain behavioral ontogeny.

In 1894, William Bateson objected to the terms “heredity” and “inheritance” in biology, on grounds of contamination with misleading notions from the everyday world. Yet after the rediscovery of Mendel's work in the spring of 1900, Bateson promoted that work as disclosing the “principles of heredity.” For historians of science, Bateson's change of mind provides a new angle on these terms at a crucial moment in their history. For philosophers of science, the case can serve as a reminder (...) of the potential of Putnam's hypothesis of a division of linguistic labor for analyzing the semantic lives of scientific kind terms.

This paper argues that our modern concept of biological heredity was first clearly introduced in a theoretical and practical setting by the generation of French physicians that were active between 1810 and 1830. It describes how from a traditional focus on hereditary transmission of disease, influential French medical men like Esquirol, Fodéré, Piorry, Lévy, moved towards considering heredity a central concept for the conception of the human bodily frame, and its set of physical and moral dispositions. The notion (...) of heredity as a natural force, with a wide ranging capabilities of transmitting differentially both fundamental and accidental characters was generalized by that generation of physicians with the help of contemporary naturalists and physiologists. By 1830 the term hérédité was widespread, and it shared the explanatory and semantic qualities of traditional medical concepts like constitution and temperament. An analysis is given of the main developments that led to the conception of biological (including human) bodies as consisting of a layered, hierarchical organization of characters, differentially affected by the laws of conservation (Heredity) and change (Inneity, Variation). The mid-century work of the French physician Prosper Lucas, Traité Philosophique et Physiologique de L'Hérédité Naturelle, is shown to be the culmination of the efforts of several generations of French physicians towards having a feasible, complexly structured notion of how heredity works.

This study explores the principles of meritocracy and heredity as formulated in the three works of early Daoist philosophy, the Laozi, Zhuangzi and Wenzi. Because Daoist philosophy emerged in critical response to the Confucian worldview, this investigation is placed against the backdrop of pertinent Confucian propositions. To this end, the study begins with a review of Confucian positions on the issue of meritocracy and heredity as expressed in the main transmitted works, as well as newly excavated texts that (...) can be associated with this intellectual tradition. The paper concludes that, while indeed rejecting the Confucian understanding of meritocracy, Daoist texts operated with their own concepts on human excellency. Moreover, the opposition between meritocracy and heredity characteristic of some Confucian works appears less pronounced in early Daoist philosophy. (shrink)

Spätestens mit Carsten Curator setzt sich das novellistische Werk Theodor Storms mit Fragen der Vererbung und des familiären Verfalls auseinander, kulminierend in Der Schimmelreiter. Die Denkfiguren, die diese Novellen strukturieren, speisen sich, wie damals üblich, aus dem Darwinismus, vor allem aber aus der psychiatrischen Lehre von der Degeneration. Letztere verdankt, wie sie selbst freimütig zugibt, ihre zentrale Grundfigur, das Aussterben eines Geschlechts über drei oder mehr Generationen, der Androhung des Zorns Gottes bei Missachtung der Zehn Gebote (Exodus 20,3ff.). Während Carsten (...) Curator und Der Schimmelreiter psychiatrisch-biologische und (para-)theologische Denkfiguren (rund um den Zorn Gottes) in Form zweier analoger, keineswegs vollständig aufeinander abbildbarer Lesarten einander gegenüberstellen, geht es in Hans und Heinz Kirch darum, das hereditäre Verhältnis der Geschlechter und deren (möglichen) Verfall rein theologisch durchzuspielen. Die Novelle stellt jedoch nicht nur den Versuch dar, das alttestamentliche Modell des Zorns Gottes zu exemplifizieren. Vielmehr werden weitere biblische Gleichnisse und Denkfiguren aus dem Neuen Testament mit diesem Modell verknüpft. Insgesamt entsteht so eine literarische Theologie des familiären Untergangs, aber auch – und das ist eine Besonderheit des rein theologischen Modells und des damit verbundenen Rückgriffs auf das Neue Testament – die Möglichkeit, diesen aufzuhalten. Alles in allem handelt es sich um ein Strukturmodell, das allen späteren novellistischen Arbeiten Storms zumindest partiell zugrunde liegt, wenn auch nie wieder so explizit auserzählt wie hier.
