Social transmission is at the core of cultural evolutionary theory. It occurs when a demonstrator uses mental representations to produce some public displays which in turn allow a learner to acquire similar mental representations. Although cultural evolutionists do not dispute this view of social transmission, they typically abstract away from the multistep nature of the process when they speak of cultural variants at large, thereby referring both to variation and evolutionary change in mental representations as well (...) as in their corresponding public displays. This conflation suggests that differentiating each step of the transmission process is redundant. In this paper, I examine different forms of interplay between the multistep nature of social transmission and the metric spaces used by cultural evolutionists to measure cultural variation and to model cultural change. I offer a conceptual analysis of what assumptions seem to be at work when cultural evolutionists conflate the complex causal sequence of social transmission as a single space of variation in which populations evolve. To this aim, I use the framework of variation spaces, a formal framework commonly used in evolutionary biology, and I develop two theoretical concepts, ‘technique’ and ‘technical space’, for addressing cases where the complexity of social transmission defies the handy assumption of a single variation space for cultural change.

Both Russell and Donnellan proposed direct, non-descriptive cognitive relations between thinkers and objects. They agreed that such relations couldn’t be initiated in evidence cases, but Donnellan, unlike Russell, thought direct cognitive relations could be transmitted from person to person. Kaplan (2012) suggests the issues of initiation and transmission are separable—allowing one to deny that evidence yields direct cognition while believing direct cognition is transmittable. Here, cases involving transmission, evidence, ordinary perception, and perception aided by technology are considered. It (...) is concluded that the same mechanism is at work in each case, and that the initiation issue cannot be separated from the transmission issue since transmission cases are evidence cases. Finally, it is argued that this doesn’t threaten the directness of the cognitive relations involved. (shrink)

Literature on bodily habit has often emphasised the inculcation of new bodily skills and embodied ways of being in practice. However, recent work demonstrates that skilled experts do focus on the body, its sensuous information, and engage in conscious and deliberate forms of bodily awareness during the performance of bodily skills. In this article, I present data from interviews with barbell coaches and yoga teachers in order to explore the social transmission of bodily knowledge. I analyse accounts from (...) these experts about the techniques and approaches they use to teach bodily skills, focusing on objective, subjective, and intersubjective strategies. I argue that while bodily knowledge is difficult to articulate, its fundamentally social basis means that it can be translated through coordinated activities and shaped by social processes. I thus advance literature on bodily knowledge by accounting for deliberation and reflexivity in learning bodily skills. (shrink)

Maswood and Rajaram examine the transmission of false memories across small and larger networks. While the spread of false memories is not inherently beneficial, Maswood & Rajaram argued that a better understanding of the formation and propagation of false memories has practical and societal implications. For example, by better understanding how false memories transmit across groups, we might be better equipped to prevent detrimental behaviors that arise as a result of “fake news.”.

Evolved dispositions influence, but do not determine, how people think about economic problems. The evolutionary cognitive approach offers important insights but underweights the social transmission of ideas as a level of explanation. The need for asocialexplanation for the evolution of economic attitudes is evidenced, for example, by immense variations in folk-economic beliefs over time and across individuals.

Many evolutionary models assume that behaviors are caused directly by genes. An implication is that behavioral uniformity should be found only in groups that are genetically uniform. Yet, the members of human social groups often behave in a uniform fashion, despite the fact that they are genetically diverse. Behavioral uniformity can occur through a variety of psychological mechanisms and social processes, such as imitation, consensus decision making, or the imposition of social norms. We present a series of (...) models in which genes code for social transmission rules, which in turn govern the behaviors that are adopted. Transmission rules can evolve in randomly formed groups that concentrate phenotypic variation at the between-group level, favoring the evolution of altruistic behaviors and other group-advantageous traits. In addition, a direct bias toward adopting altruistic behaviors can evolve. Our models begin to show how group selection can be a strong force in human evolution, despite the absence of extreme genetic variation among groups. (shrink)

From a sociological perspective, Rational Choice Theory neglects an important question: How do agents come to conceptualise choices as they do? In particular, agents not only communicate about their choices and resulting outcomes but also draw attention to options unconsidered by others. This paper presents an agent-based simulation in which different kinds of information about choices are transmitted. This approach also provides a concrete model for certain aspects of hegemonic discourse . In standard Rational Choice where options are common knowledge, (...) all actors with the same preferences should make the same decisions. By contrast if information is transmitted socially, the concerns of a majority may reduce the ability of a minority to choose options appropriate to them even without any exercise of coercion or discrimination.

Cumulative cultural knowledge [CCK], the knowledge we acquire via social learning and has been refined by previous generations, is of central importance to our species’ flourishing. Considering its importance, we should expect that our best epistemological theories can account for how this happens. Perhaps surprisingly, CCK and how we acquire it via cultural learning has only received little attention from social epistemologists. Here, I focus on how we should epistemically evaluate how agents acquire CCK. After sampling some reasons (...) why extant theories cannot account for CCK, I suggest that things aren’t as bleak as they might look. I explain how agents deserve epistemic credit for how CCK is transmitted in cultural learning by promoting a central need of their social group: The efficient and safe transmission of CCK. A good initial fit exists between this observation and Greco’s knowledge-economy framework. Ultimately, however, Greco’s account doesn’t straightforwardly account for CCK because of its strict focus on testimony. I point out two issues in the framework due to this focus. The resulting view advocates giving epistemic credit to agents when they act to promote their communities’ epistemic needs in the right way and highlights the various ways in which agents come to do this.

Cultural evolutionary theory has identified a range of cognitive biases that guide human social learning. Naturalistic and experimental studies indicate transmission biases favoring negative and positive information. To address these conflicting findings, the present study takes a socially situated view of information transmission, which predicts that bias expression will depend on the social context. We report a large‐scale experiment (N = 425) that manipulated the social context and examined its effect on the transmission of (...) the positive and negative information contained in a narrative text. In each social context, information was progressively lost as it was transmitted from person to person, but negative information survived better than positive information, supporting a negative transmission bias. Importantly, the negative transmission bias was moderated by the social context: Higher social connectivity weakened the bias to transmit negative information, supporting a socially situated account of information transmission. Our findings indicate that our evolved cognitive preferences can be moderated by our social goals. (shrink)

Humans have developed the capacity to approve or disapprove of the behavior of their children and of unrelated individuals. The ability to approve or disapprove transformed social learning into a system of cumulative cultural inheritance, because it increased the reliability of cultural transmission. Moreover, people can transmit their behavioral experiences (regarding what can and cannot be done) to their offspring, thereby avoiding the costs of a laborious, and sometimes dangerous, evaluation of different cultural alternatives. Our thesis is that, (...) during ontogeny, the evaluative communication (approval/disapproval) between parents and offspring is substituted by other evaluative communications among peers, like individuals of the same generation. Each person belongs to a reference social group with individuals that interact more intensively. Humans have developed psychological mechanisms that enable cultural transmission by being receptive to parental advice as well as their reference social group. The selective pressure that promoted these new evaluative interactions arose to facilitate the establishment of efficient cooperative relationships. In short, the social control of behavior is essential to understand human cultural transmission. (shrink)

It is argued that a shared agency account of large-scale knowledge transmission provides a viable way forward for understanding a variety of phenomena, including the transmission of knowledge via diverse technologies such as Wikipedia, Google Search, and Siri. In fact, the lessons learned arguably apply more generally than this. If the arguments of the paper are sound, much of what is said here will apply to large-scale knowledge generation as well, including knowledge generation via large-scale technologies. Finally, the (...) paper considers generative AI technologies such as ChatGPT, Gemini, and Med-PaLM, and asks whether these can be understood as either transmitting knowledge or generating it. Several models are considered for each of these possibilities. (shrink)

In rich detail Jonathan Berkey interprets the social and cultural consequences of Islam's regard for knowledge, showing how education in the Middle Ages played a central part in the religious experience of nearly all Muslims. Focusing on Cairo, which under Mamluk rule was a vital intellectual center with a complex social system, the author describes the transmission of religious knowledge there as a highly personal process, one dependent on the relationships between individual scholars and students. The great (...) variety of institutional structures, he argues, supported educational efforts without ever becoming essential to them. By not being locked into formal channels, religious education was never exclusively for the elite but was open to all. Berkey explores the varying educational opportunities offered to the full run of the Muslim population--including Mamluks, women, and the "common people." Drawing on medieval chronicles, biographical dictionaries, and treatises on education, as well as the deeds of endowment that established many of Cairo's schools, he explains how education drew groups of outsiders into the cultural center and forged a common Muslim cultural identity.

The dynamics of knowledge transmission and acquisition, or how different aspects of culture are passed from one individual to another and how they are acquired and embodied by individuals, are central to understanding cultural evolution. In small-scale societies, cultural knowledge is largely acquired early in life through observation, imitation, and other forms of social learning embedded in daily experiences. However, little is known about the pathways through which such knowledge is transmitted, especially during middle childhood and adolescence. This (...) study presents new empirical data on cultural knowledge transmission during childhood. Data were collected among the Baka, a forager-farmer society in southeastern Cameroon. We conducted structured interviews with children between 5 and 16 years of age about group composition during subsistence activities. Children’s groups were generally diverse, although children tended to perform subsistence activities primarily without adults and with same-sex companions. Group composition varied from one subsistence activity to another, which suggests that the flow of knowledge might also vary according to the activity performed. Analysis of the social composition of children’s subsistence groups shows that vertical and oblique transmission of subsistence-related knowledge might not be predominant during middle childhood and adolescence. Rather, horizontal transmission appears to be the most common knowledge transmission strategy used by Baka children during middle childhood and adolescence, highlighting the importance of other children in the transmission of knowledge.

Almost everyone believes that testimony can transmit knowledge from speaker to hearer. What some philosophers mean by this is ordinary and pedestrian-- they mean only that, in at least some cases, a speaker S knows that p, S testifies that p to a hearer H, and H comes to know that p as a result of believing S's testimony. There is disagreement about how this occurs, but that it does occur is sufficient for the transmission of knowledge in the (...) intended sense. On this understanding of transmission, the natural questions are these: (1) What conditions, in addition to speaker knowledge and speaker testimony, are sufficient for the hearer to gain testimonial knowledge?; and (2) Is speaker knowledge always necessary for testimonial knowledge? That is: Is all testimonial knowledge transmitted knowledge? (shrink)

Abstract: Pluralistic ignorance is a nasty informational phenomenon widely studied in social psychology and theoretical economics. It revolves around conditions under which it is "legitimate" for everyone to remain ignorant. In formal epistemology there is enough machinery to model and resolve situations in which pluralistic ignorance may arise. Here is a simple first stab at recovering from pluralistic ignorance by means of knowledge transmissibility.

Culture, defined as shared behavior or information within a community acquired through some form of social learning from conspecifics, is now suggested to act as a second inheritance system. Cultural processes are important in a wide variety of vertebrate species. Birdsong provides a classic example of cultural processes: cultural transmission, where changes in a shared song are learned from surrounding conspecifics, and cultural evolution, where the patterns of songs change through time. This form of cultural transmission of (...) information has features that are different in speed and form from genetic transmission. More recently, culture, vocal traditions and an extreme form of song evolution has been documented in cetaceans. Humpback whale song ‘revolutions’, where the single population-wide shared song type is rapidly replaced by a new, novel song type introduced from a neighbouring population, represents an extraordinary example of ocean basin-wide cultural transmission rivalled in its geographic extent only by humans. In this review, we examine the cultural evolutions and revolutions present in some birdsong and whale song, respectively. By taking a comparative approach to these cultural processes, we review the existing evidence to understand the similarities and differences for their patterns of expression and the underlying drivers, including anthropogenic influences, which may shape them. Finally, we encourage future studies to explore the role of innovation vs. production errors in song evolution, the fitness information present in song, and how human-induced changes in population sizes, trajectories and migratory connections facilitating cultural transmission may be driving song revolutions.

Is speaker knowledge necessary or sufficient for enabling hearers to know from testimony? Here, we offer a novel argument for the answer no, based on the systematic effects of partial belief and the hearer’s view prior to hearing testimony. Modelling partial belief by credence, we show that a requirement entailed by the principles of necessity and sufficiency apparent in the literature is inconsistent with Bayesian updating. Consequently, even when the other grounds of knowledge are in place, the audience correctly updating (...) their partial belief can block the transmission of speaker knowledge, so it need not be sufficient. Nor need speaker knowledge be necessary, because the hearer correctly updating their partial belief can put them in the position to know even though no one in the speaker’s chain knows. We articulate the correct principles of testimonial knowledge transmission. The first supports a shared-credit view of transmission. The second gives a novel and systematic argument for testimony sometimes being a generative (not transmissive) source of knowledge, an argument that makes Lackey’s statement account of testimony otiose. Finally, on at least one account of causation, the two amended principles together show how speaker knowledge can be a cause whose effect is hearer’s knowledge. (shrink)

How do we transmit or distribute knowledge, as distinct from generating or producing it? In this book John Greco examines the interpersonal relations and social structures which enable and inhibit the sharing of knowledge within and across epistemic communities. Drawing on resources from moral theory, the philosophy of language, action theory and the cognitive sciences, he considers the role of interpersonal trust in transmitting knowledge, and argues that sharing knowledge involves a kind of shared agency similar to giving a (...) gift or passing a ball. He also explains why transmitting knowledge is easy in some social contexts, such as those involving friendship or caregiving, but impossible in contexts characterized by suspicion and competition rather than by trust and cooperation. His book explores phenomena that have been undertheorized by traditional epistemology, and throws new light on existing problems in social epistemology and the epistemology of testimony. (shrink)

Active cultural transmission of fitness-enhancing behavior can be seen as a costly strategy: one for which its evolutionary stability poses a Darwinian puzzle. In this article, we offer a biological market model of cultural transmission that substitutes or complements existing kin selection-based proposals for the evolution of cultural capacities. We demonstrate how a biological market can account for the evolution of teaching when individual learners are the exclusive focus of social learning. We also show how this biological (...) market can affect the dynamics of cumulative culture. The model works best when it is difficult to have access to the observation of the behavior without the help of the actor. However, in contrast to previous non-mathematical hypotheses for the evolution of teaching, we show how teaching evolves, even when innovations are insufficiently opaque and therefore vulnerable to acquisition by emulators via inadvertent transmission. Furthermore, teaching in a biological market is an important precondition for enhancing individual learning abilities. (shrink)

Recent research into cultural transmission suggests that humans are disposed to learn, remember, and transmit certain types of information more easily than others, and that any information that is passed between people will be subjected to cognitive selective pressures that alter the content and structure so as to make it maximally transmittable. This paper presents a review of emerging research on content biases in cultural evolution with relevance to the transmission of popular narratives. This is illustrated with content (...) analysis of urban legends, which found that most exploited at least one known content bias, with emotional information and social information being the most frequent. We argue that the narratives do not succeed because of the transmission of adaptively relevant information but because of their exploitation of content biases in human cognition. (shrink)

This paper presents the hypothesis that linguistic capacity evolved through the action of natural selection as an instrument which increased the efficiency of the cultural transmission system of early hominids. We suggest that during the early stages of hominization, hominid social learning, based on indirect social learning mechanisms and true imitation, came to constitute cumulative cultural transmission based on true imitation and the approval or disapproval of the learned behaviour of offspring. A key factor for this (...) transformation was the development of a conceptual capacity for categorizing learned behaviour in value terms - positive or negative, good or bad. We believe that some hominids developed this capacity for categorizing behaviour, and such an ability allowed them to approve or disapprove of their offsprings- learned behaviour. With such an ability, hominids were favoured, as they could transmit to their offspring all their behavioural experience about what can and cannot be done. This capacity triggered a cultural transmission system similar to the human one, though pre-linguistic. We suggest that the adaptive advantage provided by this new system of social learning generated a selection pressure in favour of the development of a linguistic capacity allowing children to better understand the new kind of evaluative information received from parents.

Using samples from three diverse populations, we test evolutionary hypotheses regarding how people reason about the inheritance of various traits. First, we provide a framework for differentiat-ing the outputs of mechanisms that evolved for reasoning about variation within and between biological taxa and culturally evolved ethnic categories from a broader set of beliefs and categories that are the outputs of structured learning mechanisms. Second, we describe the results of a modified “switched-at-birth” vignette study that we administered among children and adults (...) in Puno, Yasawa, and adults in the United States. This protocol permits us to study perceptions of prenatal and social transmission pathways for various traits and to differentiate the latter into vertical versus horizontal cultural influence. These lines of evidence suggest that people use all three mechanisms to reason about the distribution of traits in the population. Participants at all three sites develop expectations that morphological traits are under prenatal influence, and that belief traits are more culturally influenced. On the other hand, each population holds culturally specific beliefs about the degree of social influence on non-morphological traits and about the degree of vertical transmission—with only participants in the United States expecting parents to have much social influence over their children. We reinterpret people's differentiation of trait transmission pathways in light of humans' evolutionary history as a cultural species. (shrink)

The new disciplines of experimental psychology and physical chemistry which emerged in late-nineteenth-century Germany were transmitted rapidly to North America, where they flourished. At the time, American higher education was growing fast and undergoing important organizational changes. It was then especially receptive to such European ideas as these new growth points in German science. However, although there were important similarities in the transmission of the two sciences, experimental psychology was changed far more than physical chemistry by the transfer. Physical (...) chemistry was able to fit into a flourishing pattern of German-inspired chemistry in higher education. Psychology was more dependent on its intellectual and social context, and the American context was quite different from that of Germany. (shrink)

Social learning and imitation is central to culture in cetaceans. The training technology used with cetaceans facilitates reinforcing imitation of one dolphin's behavior by another; the same technology, now widely used by pet owners, can lead to imitative learning in such unlikely species as dogs and horses. A capacity for imitation, and thus for cultural learning, may exist in many species.

Recently, it has been reported that maternal ACEs increase the risk of developmental delay in the offspring across generations. This mini review focuses on the direct relationship between maternal ACEs and child developmental delay, and potential mediators/moderators that associate their relationship. Six studies were identified using three search engines. The results indicated that four out of six studies reported at least one significant direct association (...) between maternal ACEs and child development. Additionally, maternal biological, psychological, and social factors were identified as mediators or moderators. In summary, we identified that maternal ACEs increased the risk of developmental delay in children via biological and psychosocial pathways. Future research should examine potential buffering factors and identify when it is crucial to break the intergenerational transmission. (shrink)

Three related issues are addressed. First, Hurley treats emulation and imitation as a straightforward dichotomy with emulation emerging first. Recent conceptual analyses and chimpanzee experiments challenge this. Second, other recent chimpanzee experiments reveal high-fidelity social transmission, questioning whether copying fidelity is the brake on cumulative culture. Finally, other cognitive processes such as pretence need to be integrated.

Ong, Caroline There was once a strong belief amongst global HIV/AIDS organisations that the key to the prevention of the sexual transmission of HIV was condom use. Other measures such as abstinence and being loyal to one partner were seen as beneficial, but secondary. Thirty years later, the evidence is mounting that behavioural change is much more effective in halting the spread of HIV than condoms.

We provide a computational model of semantic alignment among communicating agents constrained by social and cognitive pressures. We use our model to analyze the effects of social stratification and a local transmission bottleneck on the coordination of meaning in isolated dyads. The analysis suggests that the traditional approach to learning—understood as inferring prescribed meaning from observations—can be viewed as a special case of semantic alignment, manifesting itself in the behaviour of socially imbalanced dyads put under mild pressure (...) of a local transmission bottleneck. Other parametrizations of the model yield different long-term effects, including lack of convergence or convergence on simple meanings only. (shrink)

The susceptible-transmissible-removed (STR) model is a deterministic compartment model, based on the susceptible-infected-removed (SIR) prototype. The STR replaces 2 SIR assumptions. SIR assumes that the emigration rate (due to death or recovery) is directly proportional to the infected compartment’s size. The STR replaces this assumption with the biologically appropriate assumption that the emigration rate is the same as the immigration rate one infected period ago. This results in a unique delay differential equation epidemic model with the delay equal to the (...) infected period. Hamer’s mass action law for epidemiology is modified to resemble its chemistry precursor—the law of mass action. Constructing the model for an isolated population that exists on a surface bounded by the extent of the population’s movements permits compartment density to replace compartment size. The STR reduces to a SIR model in a timescale that negates the delay—the transmissible timescale. This establishes that the SIR model applies to an isolated population in the disease’s transmissible timescale. Cyclical social interactions will define a rhythmic timescale. It is demonstrated that the geometric mean maps transmissible timescale properties to their rhythmic timescale equivalents. This mapping defines the hybrid incidence (HI). The model validation demonstrates that the HI-STR can be constructed directly from the disease’s transmission dynamics.

Non-pharmaceutical interventions, including social distancing, quarantine, and isolation, are a potentially attractive means to limit the transmission of a pandemic virus. Many of these interventions are directed at children given children’s disproportionate role in amplifying epidemics. The ethics of non-pharmaceutical interventions can be analyzed using Nancy Kass’ ethics framework for public health. Such an analysis highlights the limited data supporting these interventions’ effectiveness. It also suggests the framework itself needs to be expanded to consider harms other than constraints (...) on liberty and to consider affirmative programs to mitigate these broader harms. (shrink)

John Greco (2020) sets out to create a unified virtue-theoretic account of knowledge generation and transmission in his book The Transmission of Knowledge. One of the advantages of his view is that it can defend the achievement view from a known strand of counterexamples. To accomplish that, he relies on joint agency being essential to knowledge transmission. Joint agency can be characterized as a sort of interdependent and interactive cooperation between speaker and hearer that share an intention (...) to transmit knowledge. This paper introduces the phenomenon of unwanted knowledge transmission which shows that joint agency, as Greco presents it, is not essential to knowledge transmission. Four types of unwanted knowledge transmissions will be introduced that pose threats to Greco’s account by showing that shared intention, a key characteristic of joint agency, is not present in all instances of knowledge transmission. Finally, some potential ways to defend Greco’s view will be considered and discussed. (shrink)

This is the first book to address the social organisation of modern yoga practice as a primary focus of investigation and to undertake a comparative analysis to explore why certain styles of yoga have successfully transcended geographical boundaries and endured over time, whilst others have dwindled and failed. Using fresh empirical data of the different ways in which posture practice was disseminated transnationally by Krishnamacharya, Sivananda and their leading disciples, the book provides an original perspective. The author draws upon (...) extensive archival research and numerous fieldwork interviews in India and the UK to consider how the field of yoga we experience today was shaped by historic decisions about how it was transmitted. The book examines the specific ways in which a small group of yogis organised their practices and practitioners to popularise their styles of yoga to mainstream audiences outside of India. It suggests that one of the most overlooked contributions has been that of Sivananda Saraswati (1887-1963) for whom this study finds his early example acted as a cornerstone for the growth of posture practice. Outlining how yoga practice is organised today on the world stage, how leading brands fit into the wider field of modern yoga practice and how historical developments led to a mainstream globalised practice, this book will be of interest to researchers in the field of Yoga Studies, Religious Studies, Hindu Studies, South Asian History, Sociology and Organisational Studies.

Abstractabstract:Long before COVID-19 made social distancing familiar, people with cystic fibrosis (CF) already practiced such behaviors. CF is held up as a classic example of genetic disease, yet people with CF are also susceptible to bacteria from the environment and from other CF patients. Starting in the 1980s, a bacterial epidemic in the CF population highlighted clashing priorities of connection, physical safety, and environmental protection. Policymakers ultimately called for the physical separation of people with CF from one another via (...) recommendations that reconfigured the CF community. Simultaneously, medical researchers recognized that one highly transmissible CF pathogen called cepacia was being developed for environmental applications and got the EPA to limit cepacia's environmental deployment. Environmental regulations speak to the challenge of useful microbes that harm a minority, but CF cross-infection also involves legal implications for microbial and genetic discrimination, social consequences for CF communities, and ethical questions about balancing autonomy, harms, and benefits. As scientists increasingly study connections between host genetics, microbial genetics, and infectious risks, CF is a vital referent. (shrink)

A growing and substantial body of research suggests that female sex workers play a disproportionately large role in the transmission of HIV in many parts of the world, and they are often referred to as core groups by epidemiologists, mathematical modellers, clinicians and policymakers. Male sex workers, by contrast, have received little attention and it is not known whether it is helpful to conceptualize them as a core group. This paper draws upon ethnographic research documenting social and sexual (...) networks in London and looks at the position of five male sex workers within a network comprising 193 men and seven women (as well as 1378 anonymous sexual contacts and 780 commercial contacts). In so doing, it suggests that there is no evidence to show that male sex workers are more or less likely to acquire or transmit HIV in the course of commercial sex compared with other types of sexual relationships. In addition, men engaging in non-commercial sex all reported having unprotected sex in a variety of contexts and relationships and there is no evidence to suggest that men who are not sex workers play less of a role in the transmission of HIV. In short, these data suggest that it would be inappropriate to conceptualize male sex workers as a core group. This is not to suggest that public policy should continue to overlook male sex workers.

In lieu of an abstract, here is a brief excerpt of the content:Communicating Conversion:Penitential Turn Transmission in the Early Franciscan FraternityKrijn PanstersIntroductionThe literature on religious conversion shows that there is no comprehensive inventory of individual conversion stories that may provide the basic materials for a genealogy of Christian conversion, or of a further examination of its tradition.1 The scholarly interpretations that we have almost exclusively concern conversion narratives about anonymous masses, such as the Saxons under Charlemagne, or the conversions (...) of a limited number of famous people.2 These include the "usual suspects" such as St. Paul, whose conversion led him to become a follower of Jesus,3 St. Augustine, who also converted to Christianity,4 John Wesley, whose conversion led him to begin his own ministry,5 and Thomas Merton, who converted to Catholicism and became a priest.6 To this exclusive crowd of icons of Christian conversion certainly belongs St. Francis of Assisi (†1226), [End Page 171] whose exemplary conversion experience centers on penance (recognition of himself as a sinner, conversion of the heart, rejection of worldly life, imitation of Christ) and whose case is special and exceptional in that the event of the commencement of his penitential life remains the essence of the core of his spiritual preaching and teaching.In this article, I will therefore deal with Francis's penitential turn transmission—his communication of a spiritual propositum based on conversion from sin to virtue—and thus with his main spiritual message.7 I will start with a short description of how Francis turned his conversion experience, an episode that has been studied extensively as an important part of his biography, into the cornerstone of his spiritual transmission, viz., his promotion of a new religious program. I will continue with a contextualization of Francis's communication of conversion from a broader historical-theological perspective. I will then analyze the deeper dimensions of his call to conversion, viz., his instruction of "doing penance" in terms of turning from sin to virtue. I will conclude with a reflection on the continuation of his spiritual transmission within the Franciscan order and, furthermore, on the comparison with other "conversional communications" in the Christian tradition.Francis's Communication of ConversionFrancis described his conversion to a life of "doing penance" as the outcome of an encounter with outcasts, after which "what had seemed bitter to me was turned into sweetness of soul and body" and he "delayed a little and left the world."8 In this confession, he conceptualized his religious [End Page 172] turnabout as the start of the penitential life and, with this, as an invitation to his readers to also change the orientation and direction of their lives and to switch from worldliness to otherworldliness—to the realization, from now on, not of worldly but of heavenly goods. It is very likely that Francis had already heard the call to conversion and penitential life in the encounter with certain Gospel texts.9 As is evident from his conversional account, however, he truly "first recognized himself as a sinner"10 in an encounter with lepers. It was this spiritual event, causing a moral shift from selfishness to social concern,11 that brought about a radical reorientation toward a life of faith, a remarkable religious renewal, and a rapid replacement of sin with salvation. It was also this existential experience, this self-perceived transition "from damnation to redemption," that came to represent the essence of the evangelical program that Francis developed in the following years. In the words of André Vauchez:The text of the Gospel to which Francis and his companions never ceased referring in their preaching included this dimension: "Do penance! The kingdom of heaven is at hand!" (or "is coming," according to the other version of Matthew 4:17 then in circulation). But the conversion to which they were inviting [End Page 173] their listeners was not presented as a simple preparation or preliminary step that was necessary to pass through in order to attain perfection. It already included entry into this "kingdom of heaven," which it was helping to create here and now (hinc et nunc). Far from any millenarian speculation or complex divisions of the history of salvation which certain ecclesiastical authors... (shrink)

Résumé Les missions et transmissions qui s’engagent dans les liens sociaux et familiaux ont prise sur le corps, ici défini dans sa double composition de corps biologique et de corps érotique. Les messages du sexuel inconscient infiltrent l’architecture psychosomatique et subvertissent les relations familiales, sociales, intersubjectives. Après quelques rappels théoriques, l’article aborde plusieurs situations cliniques prises dans la littérature psychanalytique (cas de Dora pour Freud) et dans la pratique clinique récente avec des patients présentant des pathologies somatiques diverses : pelade (...) totale décalvante, infarctus du myocarde, suivi post-greffe cardio-pulmonaire.

This article introduces an agent-based and a system-dynamics model investigating the cultural transmission of frequent collective rituals. It focuses on social function and cognitive attraction as independently affecting transmission. The models focus on the historical context of early Christian meals, where various theoretically inspiring trends in cultural transmission of rituals can be observed. The primary purpose of the article is to contribute to theorizing about cultural transmission of rituals by suggesting a clear operationalization of their (...) social function and cognitive attraction. Furthermore, the article challenges recent trends in the field by providing a theoretically feasible model for how, under certain conditions, cognitive attraction can influence the transmission to a relatively greater extent than social function. In the system dynamics model we reproduce the results of our agent-based model while putting some of our basic operational assumptions under scrutiny. We consider approaching social function and cognitive attraction in isolation as a preliminary but necessary step in the process of creating more complex models of the cultural selection of rituals, where the two aspects will be combined to produce ritual forms with greater correspondence to real-world religious rituals.

L’étude de l’impact émotionnel des séparations entre les mères migrantes, leurs enfants confiés au pays d’origine et ceux nés en pays d’accueil permet d’apporter un éclairage sur une problématique non négligeable au sein d’institutions médico-sociales. Cet article vise à analyser certains effets de ces séparations à partir de l’analyse de cinq entretiens avec des mères migrantes et au travers d’une méthode d’analyse qualitative. Les paramètres mis en avant sont ceux qui influent sur les modalités de choix de confiage des enfants (...) au moment du départ du pays d’origine, les conséquences dépressogènes pour les mères des séparations à long terme et leurs effets sur les interrelations entre frères et sœurs. L’absence de lien proximal avec les enfants confiés conduit les mères à faire appel à des stratégies de transmission de valeurs culturelles éducatives pour maintenir les liens dans la fratrie.

Greco argues that knowledge by transmission involves joint agency whose norms are governed by the quality of the social relations in the transmission, and these norms differ from the norms generating knowledge in the source. This approach to the transmission of knowledge allows Greco to respond to three common arguments against the rationality of religious belief on testimony: the argument against belief in miracles, the argument from luck, and the argument from peer disagreement. I agree with (...) Greco’s position on the transmission of knowledge or reasonable belief in these cases and argue that the distinction between first person and third person reasons for belief can strengthen his position. The experience upon which a belief is based can be transferred intersubjectively and strengthens the ground for the belief based on experience, including the belief in miracles. Trust is another first person reason for belief, not only a background condition for reasonable transmission, and it also can be transmitted and is an important component in the formation and preservation of traditions. This feature permits a reply to the arguments from luck and from disagreement with people outside the tradition. But this feature also shows why we find these arguments threatening since we are rationally committed to a minimal degree of trust in all other reasonable persons. (shrink)

The principal contrasts that Jagiello et al. highlight are among many cultural transmission biases we now know of. I suggest they are also reflected more widely in social learning decisions among nonhuman animal cultures governing whether cultural innovations spread, or are instead over-ridden by immigrants' conformity in their new group. Such conformity may serve either informational or social-integrative functions.

Pluralistic ignorance is a nasty informational phenomenon studied widely in social psychology and theoretical economics. It revolves around conditions under which it is "legitimate" for everyone to remain ignorant. In formal epistemology there is enough machinery to model and resolve situations in which pluralististic ignorance may arise. Here is a simple …rst stab at recovering from pluralistic ignorance by means of knowledge transmissibility.
