August Weismann is famous for having argued against the inheritance of acquired characters. However, an analysis of his work indicates that Weismann always held that changes in external conditions, acting during development, were the necessary causes of variation in the hereditary material. For much of his career he held that acquired germ-plasm variation was inherited. An irony, which is in tension with much of the standard twentieth-century history of biology, thus exists – Weismann was not a Weismannian. (...) I distinguish three claims regarding the germ-plasm: (1) its continuity, (2) its morphological sequestration, and (3) its variational sequestration. With respect to changes in Weismann’s views on the cause of variation, I divide his career into four stages. For each stage I analyze his beliefs on the relative importance of changes in external conditions and sexual reproduction as causes of variation in the hereditary material. Weismann believed, and Weismannism denies, that variation, heredity, and development were deeply intertwined processes. This article is part of a larger project comparing commitments regarding variation during the latter half of the nineteenth century. (shrink)

This chapter offers a general outline of Schopenhauer’s peculiarly named concept of the 'acquired character’ and explains its basic function in his ethical thought. For Schopenhauer, a person of acquired character is someone who knows the ways of acting (Handlungsweise) that are most expressive of their individuality and who allows that self-knowledge to structure their practical and emotional life. In keeping with certain elements of his psychological determinism, acquired character is not the acquisition of a ‘new’ character; (...) rather, it is the acquisition of self-knowledge of one’s essentially fixed empirical character. It is part of the argument of this chapter that by introducing the acquired character into his reflections on human action and agency Schopenhauer weaves a certain view of individual flourishing (eudaimonia) into his ethics. There are two central ingredients of Schopenhauer’s conception of eudaimonia, and both are linked to the acquired character. The first is self-knowledge; the second is a sense of personal autonomy that follows in the wake of the first. The chapter ends with a brief attempt to connect Schopenhauer’s concept of acquired character to contemporary debates in ethics concerning autonomy, practical identity, and what some call the ‘normative significance of self’.

Scholars studying the history of heredity suggest that during the 19th-century biologists and anthropologists viewed characteristics as a collection of blended qualities passed on from the parents. Many argued that those characteristics could be very much affected by environmental circumstances, which scholars call the inheritance of acquired characteristics or "soft" heredity. According to these accounts, Gregor Mendel reconceived heredity - seeing distinct hereditary units that remain unchanged by the environment. This resulted in particular traits that breed (...) true in succeeding generations, or "hard" heredity. The author argues that polygenist anthropology (an argument that humanity consisted of many species) and anthropometry in general should be seen as a hardening of heredity. Using a debate between Philadelphia anthropologist and physician, Samuel G. Morton, and Charleston naturalist and reverend, John Bachman, as a springboard, the author contends that polygenist anthropologists hardened heredity by conceiving of durable traits that might reappear even after a race has been eliminated. Polygenists saw anthropometry (the measurement of humans) as one method of quantifying hereditary qualities. These statistical ranges were ostensibly characteristics that bred true and that defined racial groups. Further, Morton's interest in hybridity and racial mixing demonstrates that the polygenists focused as much on the transmission and recognition of "amalgamations" of characters as they did on racial categories themselves. The author suggests that seeing race science as the study of heritable, statistical characteristics rather than broad categories helps explain why "race" is such a persistent cultural phenomenon.

Advocates of Extended Evolutionary Synthesis claim that the gene-centric framework of Modern Synthesis (MS) inadequately addresses epigenetics and extended heredity. Historically, epigenetic inheritance relates to Lamarck's inheritance of acquired characters, which was widely accepted before the dominance of MS. In this talk, I argue that the challenge posed by epigenetic inheritance to the gene-centric view arises partly from the ambiguous use of "gene," "phenotype," and "environment" concepts. A functional analysis of the gene concept played in the formal (...) evolutionary models shows that the gene can include materials like exogenes, demonstrating the flexibility of evolutionary theory beyond the verbal MS. Properly understanding the evolutionary gene concept reveals that incorporating epigenetic inheritance does not demand a radical revision of the contemporary evolutionary theory. (shrink)

Transformations of Lamarckism is an edited volume arising from a workshop to commemorate the bicentenary of the publication of Philosophie Zoologique. The contributed chapters discuss the history of Lamarckism, present new developments in biology that could be considered to vindicate Lamarck, and argue for a revision, if not a revolution, in evolutionary theory. My review argues that twentieth and twenty-first century conceptions of Lamarckism can be considered a reaction to August Weismann’s uncompromising rejection of the inheritance of acquired (...) class='Hi'>characters in the late nineteenth century. Weismann rejected the inheritance of acquired characters both as a proximate mechanism of heredity and as an ultimate cause of adaptation. I argue that Weismann’s proximate claim is still valid for the kind of mechanism that he had in mind but that the inheritance of acquired characters has come to refer to many different processes, some of which undoubtedly do occur. However, processes of physiological adaptation and adaptive plasticity, even if transgenerational, do not challenge Weismann’s claim about the ultimate causes of adaptation because these processes can be understood as evolving by natural selection. Finally, I discuss some of the emotional and aesthetic reasons why many find Lamarckism an attractive alternative to hard-core neo-Darwinism. (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)

This chapter contains section titled: The Relation of Genotype to Phenotype Statistical Approaches to the Study of Quantitative Characters Problems Raised by Statistical Methodologies Making Quantitative Trait Genes Real Bibliography.

This article shows how Lamarckism was essential in the birth of the French school of molecular biology. We argue that the concept of inheritance of acquired characters positively shaped debates surrounding bacteriophagy and lysogeny in the Pasteurian tradition during the interwar period. During this period the typical Lamarckian account of heredity treated it as the continuation of protoplasmic physiology in daughter cells. Félix d’Hérelle applied this conception to argue that there was only one species of bacteriophage and (...) Jules Bordet applied it to develop an account of bacteriophagy as a transmissible form of autolysis and to analyze the new phenomenon of lysogeny. In a long-standing controversy with Bordet, Eugène Wollman deployed a more morphological understanding of the inheritance of acquired characters, yielding a particulate, but still Lamarckian, account of lysogeny. We then turn to André Lwoff who, with several colleagues, completed Wollman’s research program from 1949 to 1953. We examine how he gradually set aside the Lamarckian background, finally removing inheritance of acquired characters from the resulting account of bacteriophagy and lysogeny. In the conclusion, we emphasize the complex dual role of Lamarckism as it moved from an assumed explanatory framework to a challenge that the nascent molecular biology had to overcome. (shrink)

Galton greeted Darwin's theory of pangenesis with enthusiasm, and tried to test the assumption that the hereditary particles circulate in the blood by transfusion experiments on rabbits. The failure of these experiments led him to reject this assumption, and in the 1870s he developed an alternative theory of heredity, which incorporated those parts of Darwin's theory that did not involve the transportation of hereditary particles throughout the system. He supposed that the fertilized ovum contains a large number of hereditary (...) elements, which he collectively called the "stirp," a few of which are patent, developing into particular cell types, while the rest remain latent; the latent elements can be transmitted to the next generation, while the patent elements, with rare exceptions, cannot since they have developed into cells. The problem with this theory is that it does not explain the similarity between parent and child unless there is a high correlation between latent and patent elements. Galton probably came to realize this problem during his subsequent statistical work on heredity, and he quietly dropped the idea that patent elements are not transmitted in Natural Inheritance (1889). Galton thought that brothers and sisters had identical stirps, and he attributed differences between them to variability in the choice of patent elements from the stirp, that is to say to developmental variability. He attributed the likeness of monozygotic twins to the similarity of their developmental environment. Galton's twin method was to track the life history changes of twins to see whether twins who were similar at birth diverged in dissimilar environments or whether twins who were dissimilar at birth converged in similar environments. It is quite different from the modern twin method of comparing the similarities between monozygotic and dizygotic twins, on the assumption that monozygotic twins are genetically identical whereas dizygotic twins are not. It has been argued that Galton foreshadowed Weismann's theory of the continuity of the germ-plasm, but this is only true in a weak sense. They both believed that the inheritance of acquired characters was either rare or impossible, but Galton did not forestall the essential part of Weismann's theory, that the germ-plasm of the zygote is doubled, with one part being reserved for the formation of the germ-cells.

The opening chapter of this work is a comprehensive “Historical Overview of the Hereditary Puzzle.” Goldie Morgentaler's analysis of theories of heredity before Mendel will interest students of biological science. She admits that “resurrecting such theories without contamination from subsequent knowledge often requires an imaginative leap.” Very true. There have been such profound advances in the science of genetics since that time, with the avalanche of discoveries during the past half century, that much of the previous thought now falls (...) in the realm of philosophical fantasy.These early concepts were those to which Charles Dickens was exposed for most of his life. His literary reaction to them is exhaustively analyzed in the subsequent two parts of the book. The first of these is entitled “Heredity and the Individual,” and the second is “The Public Face of Heredity.” The latter includes interesting discussion of class and race, with analyses of the last three novels. These indicate that Dickens's views on heredity changed during his later life, perhaps influenced by Darwin, whose work he had read … and vice versa.The author is to be admired for her detailed knowledge of Dickens's works and his characters. For a reviewer who has been steeped in evidence‐based medicine and science for most of his career, it seems that much of the speculation regarding heredity in the nineteenth century is tenuous and far‐fetched. While Dickens engaged the topic of heredity many times, he appears to have followed the general trend of that era by showing little consistency in his views. This is not surprising in light of the paucity of scientific evidence at that time.While the title implies a study of Dickens and heredity, the substance covers a much wider field, with ventures into ethics, morality, religion, psychology, philosophy, sociology, and more. The appended notes tell of assiduous research and concentration. To the pragmatic reader it sometimes appears that Morgentaler makes observations and draws conclusions that are more profound than Dickens himself might have achieved, or admitted. This is, of course, a common diversion in revisionist studies of well‐known authors and other celebrities.It is inevitable that the perennial question of the relative strength of nature and nurture must have prominence in this study. In his earlier novels Dickens implied support for the notion that goodness and virtue were heritable traits allied to beauty and good physical appearance. Morgentaler returns repeatedly to this question in many aspects. In her final chapter she points out that Dickens's views changed, paradoxically, after The Origin of Species was published, toward the end of his life. He then gave less weight to the influence of heredity. She has, perhaps, missed an opportunity of recording that Dickens noticed hereditary factors in alcoholism and longevity. In the case of Jenny Wren's family, Mr. Cleaver was “like his own father, a weak wretched trembling creature, falling to pieces, never sober” . The Wardle family in Pickwick Papers showed familial longevity in that “only one member hasn't lived to eighty‐five, and he was beheaded by one of the Henrys.”The relationship of some of the discussion to heredity is profound, often remote, even cryptic. To those who are hybrids of a scientific historian and an obsessive Dickens aficionado, this work will be absorbing. Unfortunately for the author and the publisher, such hybrids are probably rare—but I hope not extinct. To the pure scientist this work might be an uphill exercise. The production of the book is faultless. (shrink)

The probing readings of Putting On Virtue offered by Sheryl Overmyer, Darlene Weaver, and James Foster provide a welcome opportunity for further reflection on key questions: Was Aquinas really concerned with the status of pagan virtues? Can we properly understand a thinker whose driving questions are not the same as our own without taking up a stance of pure deference? Can an inquiry into hyper-Augustinian anxiety over acquired virtue assist us in arriving at an account of positive self-regard? Can (...) an account that stresses the graced character of all virtue formation be coherent? And can it do justice to the ways in which Christians reached for accounts of infused virtue precisely in order to affirm how grace overcomes the ways in which fortune hounds acquired virtue? I respond affirmatively to all of the above. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Nature and Nurture in French Ethnography and Anthropology, 1859-1914Martin StaumThe adaptability of non-European peoples to "civilization" was a critical issue deriving from the perennial nature-nurture question that haunted debates in the human sciences in late nineteenth-century France.1 The emerging scholarly disciplines of anthropology and ethnography helped provide a scientific veneer that bolstered existing cultural prejudices concerning the innate limitations or retarded development of non-Europeans. Certainly there were many other (...) pragmatic reasons for imperial expansion, and racists did not automatically become imperialists. But if, as Edward Said contended, imperialism "depends upon the idea of having an empire," there is no doubt that many ethnographers and anthropologists helped legitimate the idea.2 Their debates retain a resonance in our twenty-first century postcolonial world struggling with questions of identity, integration, and cultural diversity.Relying on reports from travelers, missionaries, or colonial officials, human scientists from across the political and religious spectrum justified European superiority. Although a few journalists and philosophers outside the scholarly societies represented a minority anti-imperialist counter-current, the remarkable pervasiveness of hierarchical thinking affected both socially radical anthropologists and more conservative ethnographers.3 While ethnographers proclaimed universal fraternity, they conceded that physical differences affected [End Page 475] intellect and character. The later attack on hereditarianism by Durkheimian sociologists and isolated anthropologists with the catalyst of the Dreyfus Affair is all the more striking.4 As George Stocking has argued concerning a British Victorian thinker, the cultural differences between Europeans and non-Europeans became so entangled with biological issues that there was "difficulty conceptualizing them except in terms of 'race.' "5The two most notable anthropological scholarly societies of the late nineteenth century, both founded in 1859, were the Société d'ethnographie orientale et américaine and the Société d'anthropologie de Paris. Historians have justifiably noted their mutual aversion and have contrasted their differences over scientific method, politics, and religion.6 The ethnographers, inspired by a student of Japanese language and Asian religion, Léon de Rosny (1837-1914), were largely linguists and specialists in Asian texts and pre-Columbian codices that represented partly civilized peoples. Rosny invented the term "ambiantisme" for a philosophy that ostensibly privileged the cultural milieu rather than inborn human nature.7 The society membership varied between 115 in 1864 and 470 in 1878, though it declined to 165 by 1903.8 As a group, compared to the anthropologists, they were more politically conservative, more socially elite, and more inclined toward conventional religion, with its belief in the unity of the species. Their "science of destiny" stressed human freedom and unalterably opposed philosophical materialism.9 [End Page 476]The anthropologists, headed by physician and anatomist Paul Broca (1824-80) consisted of a hard core of like-minded medically trained colleagues. The anthropologists' membership peaked around 500 both in 1885 and 1905, though, they, too declined to 165 by 1914.10 Historians have analyzed the nature-nurture issue more subtly for the anthropologists.11 While the Society almost always expressed interest in both physical and cultural spheres, they privileged the study of crania as an index to the intellectual and moral characteristics of "races." The more extreme hereditarians thought that the nature of allegedly inferior "races" precluded perfectibility. Armand de Quatrefages (1810-92), professor of anthropology at the Muséum national d'histoire naturelle and pioneer of the so-called Muséum school, in his later years cast doubt on whether physical indicators actually demonstrated human superiority. However, the Muséum school did not generally renounce racial hierarchy, though they believed that environmental influences formed and continued to shape human varieties.12 In addition, philosophical materialists, militant atheists, and politically radical thinkers dominated the society in the generation after Broca's death. Almost all were neo-Lamarckians who leavened the idea of a fixed human nature with the possibility of adaptation to a milieu and transmissible acquired characteristics.13 The medical physiologist Charles Richet reported that "heredity and milieu are not antagonistic, but synergistic."14 However, many accounts underplay the differential application of neo-Lamarckianism. In this "racial evolutionist paradigm" already noticed by Laurent Mucchielli, even the Muséum school found only civilized people adaptable... (shrink)

The author engages a question raised about theories of nonexistent objects. The question concerns the way names of fictional characters, when analyzed as names which denote nonexistent objects, acquire their denotations. Since nonexistent objects cannot causally interact with existent objects, it is thought that we cannot appeal to a `dubbing' or a `baptism'. The question is, therefore, what is the starting point of the chain? The answer is that storytellings are to be thought of as extended baptisms, and the (...) details of this response receive attention in the paper. Once the storytelling is complete, and the characters have been baptized, a priori metaphysical principles linking the storytelling with the realm of nonexistent objects provide the referential, non-causal connection between the names used in the storytelling and the objects denoted by such names.

The argument of this paper is that we should think of the extension of cognitive abilities and cognitive character in integrationist terms. Cognitive abilities are extended by acquired practices of creating and manipulating information that is stored in a publicly accessible environment. I call these cognitive practices (2007). In contrast to Pritchard (2010) I argue that such processes are integrated into our cognitive characters rather than artefacts; such as notebooks. There are two routes to cognitive extension that I (...) contrast in the paper, the first I call artefact extension which is the now classic position of the causal coupling of an agent with an artefact. This approach needs to overcome the objection from cognitive outsourcing: that we simply get an artefact or tool to do the cognitive processing for us without extending our cognitive abilities. Enculturated cognition, by contrast, does not claim that artefacts themselves extend our cognitive abilities, but rather that the acquired practices for manipulating artefacts and the information stored in them extend our cognitive abilities (by augmenting and transforming them). In the rest of the paper I provide a series of arguments and cases which demonstrate that an enculturated approach works better for both epistemic and cognitive cases of the extension of ability and character.

The opening words of the second book of Aristotle’s Nicomachean Ethics are as familiar as any in his corpus: Excellence of character results from habituation [ethos]—which is in fact the source of the name it has acquired [êthikê], the word for ‘character-trait’ [êthos] being a slight variation of that for ‘habituation’ [ethos]. This makes it quite clear that none of the excellences of character [êthikê aretê] comes about in us by nature; for no natural way of being is changed (...) through habituation [ethizetai]. Equally familiar, unfortunately, is the characterization of Aristotle’s notion of character formation as a form of habituation by means of the repetition of actions which results in a “habit” in the same way that a weight lifter produces muscles through the repetition of exertions. As a 19th century commentator remarked on the passage above, “[insert Grant].” From a Socratic perspective, such a view of becoming good seems hopelessly rigid and unconnected to the intellectual development which knowledge of the good requires. Habit and habituation in Aristotle seem eminently familiar and eminently unphilosophical. Such a view would be mistaken on at least three counts. First, the notion of character formation (to use the broadest possible term for the phenomenon of habituation) in Aristotle is significantly more complicated than the notion that through habituation one develops good habits which are what we mean by ethical virtue. Although character formation includes the development of proper emotional responses, such as taking pleasure in what is fine and being repulsed by what is shameful, it is equally concerned with cognitive development independent of the intellectual virtues. Second, although Aristotle’s terms for “ethics” (êthica), character-trait (êthos), and habituation (ethos, ethismos, or ethizetai) are linguistically and conceptually interrelated, his notion of “ethical state” (hexis) is both linguistically and conceptually quite distinct from the notion of “habit,” at least as we use that term today. As one Aristotle translator has put it, “A hexis is not only not the same thing as a habit, but is almost exactly its opposite.” For Aristotle, a hexis is a dynamic equilibrium which, although always productive of virtuous actions, is nonetheless the basis for being virtuous in varied circumstances. Thirdly, once Aristotle’s notion of a character state is retrieved from its false association with “habit” and repetitive habituation, one sees that its apparent divorce from practical reason is more a fixture of Aristotle’s analytical method and its connotations of inflexibility or fixedness are in fact antithetical to Aristotle’s description of ethical virtue. Rather than view ethical “character” in its Greek etymological sense as an indelibly fixed or engraved mark or stamp (charactêr) upon one’s soul, Aristotle’s notion of ethical character (êthos) or virtue (aretê) captures the notion of a virtuoso who is responsive in an excellent fashion to what reason perceives in particular and changing circumstances.

Prosper Lucas (1808–1885) is a unique figure in the history of psychiatric genetics. A physician-alienist, he authored one of the most important books on human genetics in the mid-19th century cited frequently by Darwin: the 1,500 page treatise—Philosophical and Physiological Treatise on Natural Heredity (1847–1850). This book contained a novel theory of the nature of inheritance and a detailed review of the heredity of a range of human traits and disorders, including various forms of insanity. Lucas postulated four (...) forms of heredity (direct, crossed, indirect, and atavistic), supported the importance of hereditary factors in insanity, accepted the inheritance of acquired characteristics, considered it important to examine both ancestors and collateral relatives, and recognized that heredity could influence both primary insanity and insanity secondary to other medical conditions. He reviewed the then available literature on most major forms of insanity including separate sections on hallucinations and suicidal monomania. The literature consisted of case reports of unusual families with high concentrations of illness. Lucas advocated for the homogeneity of transmission of forms of illness in families but recognized that—just as the form of illness could evolve within individuals over time—it could change forms when transmitted between relatives.

Determinants of synesthetic color choice for the Japanese logographic script, Kanji, were studied. The study investigated how synesthetic colors for Kanji characters, which are usually acquired later in life than other types of graphemes in Japanese language , are influenced by linguistic properties such as phonology, orthography, and meaning. Of central interest was a hypothesized generalization process from synesthetic colors for graphemes, learned prior to acquisition of Kanji, to Kanji characters learned later. Results revealed that color choices (...) for Kanji characters depend on meaning and phonological information. Some results suggested that colors are generalized from Hiragana characters and Arabic digits to Kanji characters via phonology and meaning, respectively. Little influence of orthographic information was observed. The findings and approach of this study contributes to a clarification of the mechanism underlying grapheme-color synesthesia, especially in terms of its relationship to normal language processing.

This is a response paper to Daniel Russell's paper in the same volume. I raise some challenges to Russell's model of virtue acquisition which draws extensively on the CAPS model in psychology and on parallels between virtues and skills.

Written for non-experts, this volume introduces the mechanisms that underlie reticulate evolution. Chapters are either accompanied with glossaries that explain new terminology or timelines that position pioneering scholars and their major discoveries in their historical contexts. The contributing authors outline the history and original context of discovery of symbiosis, symbiogenesis, lateral gene transfer, hybridization or divergence with gene flow, and infectious heredity. By applying key insights from the areas of molecular (phylo)genetics, microbiology, virology, ecology, systematics, immunology, epidemiology and computational (...) science, they demonstrate how reticulate evolution impacts successful survival, fitness and speciation. Reticulate evolution brings forth a challenge to the standard Neo-Darwinian framework, which defines life as the outcome of bifurcation and ramification patterns brought forth by the vertical mechanism of natural selection. Reticulate evolution puts forward a pattern in the tree of life that is characterized by horizontal mergings and lineage crossings induced by symbiosis, symbiogenesis, lateral gene transfer, hybridization or divergence with gene flow, and infective heredity, making the “tree of life” look more like a “web of life.” On an epistemological level, the various means by which hereditary material can be transferred horizontally challenges our classic notions of units and levels of evolution, fitness, modes of transmission, linearity, communities, and biological individuality. The case studies presented examine topics including the origin of the eukaryotic cell and its organelles through symbiogenesis; the origin of algae through primary and secondary symbiosis and dinoflagellates through tertiary symbiosis; the superorganism and holobiont as units of evolution; how endosymbiosis induces speciation in multicellular life forms; transferrable and non-transferrable plasmids and how they symbiotically interact with their host; the means by which pro- and eukaryotic organisms transfer genes laterally (bacterial transformation, transduction and conjugation as well as transposons and other mobile genetic elements); hybridization and divergence with gene flow in sexually-reproducing individuals; current (human) microbiome and viriome studies that impact our knowledge concerning the evolution of organismal health and acquired immunity; and how symbiosis and symbiogenesis can be modelled in computational evolution.

Indirect situationist critiques of virtue ethics grant that virtue exists and is possible to acquire, but contend that given the low probability of success in acquiring it, a person genuinely interested in behaving as morally as possible would do better to rely on situationist strategies - or, in other words, strategies of environmental or ecological engineering or control. In this paper, I develop a partial answer to this critique drawn from work in early Confucian ethics and in contemporary philosophy and (...) psychology. From early Confucian ethics, I lean on the concept of li, or ritual. Ritual represents both a set of situational manipulations that are especially effective at directly producing moral behavior and at indirectly cultivating virtue over time, and also a virtue that consists of facility with and expertise in these situational manipulations. Appealing to the particular example of social power, I then argue that one is justified in attempting to acquire virtue if one knows that one will frequently encounter circumstances in which purely situationist strategies lose effectiveness, if these circumstances also carry moral urgency: the risk of great harm or opportunity for great benefit to others is high, and if utilizing the potent combination of situationist strategies and virtue envisioned by the early Confucians as ritual is possible.

I The existence of the legal profession is something most lawyers take for granted. Lawyers of course do many different things, and lead different sorts of lives, but those who make their living in the law tend to assume, without much reflection, that they have a bond or association of some sort with others who do the same and believe they share something important in common with them. It is not at all clear, however, what this common element is, and (...) the great diversity of tasks that lawyers perform – representing litigants, counseling clients, advising legislators, administering government programs, and deciding cases – can easily make one doubt whether the search for a link leads to anything but empty generalities. One may, of course, conclude that the main law jobs, as Karl Llewellyn called them, have nothing important in common, and that the legal profession is only a name for a disconnected collection of pursuits with no substance or reality of its own. This is not, however, a very satisfying view, to lawyers at least, and is likely to provoke the quick reply that what lawyers share in common is after all quite easy to discern. All lawyers, regardless of the nature of their work, possess a general knowledge of the law which they have acquired through a specialized program of instruction; laypersons lack such knowledge and it is this, one might argue, which marks the line between those who are lawyers and those who are not and, thus, defines the scope and nature of the profession.

The application and practice of virtue ethics raises an important question: How do we become virtuous? The pessimistic mainstream view is that virtue can only be cultivated in children who still have malleable characters and virtuous predispositions. This paper argues that even adults can cultivate virtues. We can cultivate virtues by using the empirically tested techniques of cognitive behavioural therapy (CBT) – if they work in the treatment of difficult problems like depression or phobias, then they should also work (...) to ameliorate our character. This paper develops an account of cognitive behavioural virtue. To this purpose, it first introduces CBT’s theoretical framework, second it shows how this framework naturally integrates with Aristotelian rather than Stoic virtue theory, third it proposes how CBT’s techniques can be applied in the cultivation of virtue. Finally, it examines some of the proposal’s theoretical consequences and shows its advantages over competing accounts, notably Stichter’s account of virtue cultivation as skill acquisition. (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.

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)

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)

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)
