Many attempts have been made to explain the rise of religious phenomena based on evolutionary models, which attempt to account for the way in which religion can constitute a useful system to increase the fitness of both the individual and the group. These models implicitly mean that beliefs are simply effective adaptations to the environment and in this sense they cannot be truly accepted by those who adhere to the religions in question. In this paper, I use the evolution of (...) culture model elaborated by Cavalli Sforza to propose an approach that can explain the change of institutionalized religions over a more limited time frame than the long times of biological evolution. This model could be heuristically effective in the study of religious phenomena and could also be applicable in terms of theology and philosophy of religion. Given the limits of space, I will only try to take a few steps in this direction, trying to answer some of the major questions that arise about such an approach. In particular, one may ask whether, unlike others, the evolution of culture model applied to religions can make it possible to put into brackets - or to remain agnostic about - the value and the truth of the beliefs and precepts of the religion which is studied.

From the 1960s, mathematical and computational tools have been developed to arrive at human population trees from various kinds of serological and molecular data. Focusing on the work of the Italian-born population geneticist Luigi Luca Cavalli-Sforza, I follow the practices of tree-building and mapping from the early blood-group studies to the current genetic admixture research. I argue that the visual language of the tree is paralleled in the narrative of the human diasporas, and I show how the tree (...) was actually mapped onto the surface of the earth. This visual and textual structure is mirrored in the liberal discourse of unity in diversity that has been criticized as running counter to the socio-political effects of human population genetics. From this perspective, one may ask how far the phylogenetic diagram in its various forms is a manifestation of the physics of power that according to Michel Foucault consists in mechanisms that analyse distributions, movements, series, combinations, and that uses instruments to render visible, to register, to differentiate and to compare. It is one among other disciplinary technologies that ensure the ordering of human diversity. In the case of intra-human phylogenetic trees, population samples and labels are one issue. Another is that the separated branches seem to show groups of people, who have in reality been interacting and converging, as isolated. Often based on so-called isolated peoples, molecular tree diagrams freeze a hierarchical kinship system that is meant to represent a state before the great historical population movements. (shrink)

Ever since The Origin of Species, but increasingly in recent years, parallels and analogies have been drawn between biological and cultural evolution, and methods, concepts, and theories that have been developed in evolutionary biology have been used to explain aspects of human cultural change (e.g., Muller 1870; Darwin [1871] 2003; Pitt-Rivers 1875; James 1880; Huxley 1955; Gerard et al. 1956; Campbell 1975; Cavalli-Sforza and Feldman 1981; Durham 1992; Henrich and McElreath 2003; Mesoudi et al. 2004, 2006; Boyd and (...) Richerson 2005; Richerson and Boyd 2005). Many others, however, while accepting the need for some form of evolutionary approach to culture, have consistently emphasized the differences between biological and cultural evolution (e.g., Gabora 2004; Sperber and Claidiere 2006; Tëmkin and Eldredge 2007), with these differences often presented as being problematic for existing evolutionary analyses of culture. Here I argue that this is largely a false debate, given that its protagonists agree on the majority of key points. Apparent disagreement may stem partly from simple differences in emphasis, and partly from the diversity of both biological and cultural evolutionary processes. (shrink)

Evolutionary models can explain the dynamics of populations, how genetic, genotypic, or phenotypic frequencies change with time. Models incorporating chance, or drift, predict specific patterns of change. These are illustrated using classic work on blood types by Cavalli-Sforza and his collaborators in the Parma Valley of Italy, in which the theoretically predicted patterns are exhibited in human populations. These data and the models display properties of ensembles of populations. The explanatory problem needs to be understood in terms of (...) how likely an observed change, in either a population or an ensemble, would be under drift alone; this is fundamentally a matter of chance. Understood in this way, issues of drift and chance undercut most recent philosophical, but not biological, discussions of the role of "genetic drift.". (shrink)

Linguists intuitions about language change can be captured by adynamical systems model derived from the dynamics of language acquisition.Rather than having to posit a separate model for diachronic change, as hassometimes been done by drawing on assumptions from population biology (cf.Cavalli-Sforza and Feldman, 1973; 1981; Kroch, 1990), this new modeldispenses with these independent assumptions by showing how the behavior ofindividual language learners leads to emergent, global populationcharacteristics of linguistic communities over several generations. As thesimplest case, we formalize the (...) example of two grammars and show that eventhis situation leads directly to a nonlinear (quadratic) dynamical system.We study this one parameter model in a variety of situations for differentkinds of acquisition algorithms and maturational times, showing howdifferent learning theories can have very different evolutionaryconsequences. This allows us to formulate an evolutionary criterion for theadequacy of grammatical and learning theories. An application of thecomputational model to the historical loss of Verb Second from Old French toModern French is described showing how otherwise adequate grammaticaltheories might fail the evolutionary criterion.

A. W. F. Edwards is one of the most influential mathematical geneticists in the history of the discipline. One of the last students of R. A. Fisher, Edwards pioneered the statistical analysis of phylogeny in collaboration with L. L. Cavalli-Sforza, and helped establish Fisher's concept of likelihood as a standard of statistical and scientific inference. In this book, edited by philosopher of science Rasmus Grønfeldt Winther, Edwards's key papers are assembled alongside commentaries by leading scientists, discussing Edwards's influence (...) on their own research and on thinking in their field overall. In an extensive interview with Winther, Edwards offers his thoughts on his contributions, their legacy, and the context in which they emerged. This book is a resource both for anyone interested in the history and philosophy of genetics, statistics, and science, and for scientists seeking to develop new algorithmic and statistical methods for understanding the genetic relationships between and among species both extant and extinct.

The idea that cultural evolution exhibits variation, competition, and inheritance and therefore can be studied by adjusting the Darwinian theory of evolution by natural selection is an attractive one. It has been argued by a number of authors (e.g., Campbell 1960; Monod 1970; Dawkins 1976; Cavalli-Sforza and Feldman 1981; Boyd and Richerson 1985; Durham 1991; Aunger 2002; Mesoudi et al. 2004) and pursued in a variety of ways, some (Dawkins and memeticists) staying close to the Darwinian model, others (...) (e.g., Boyd, Richerson, and their collaborators) being more innovative. We agree that there are relevant analogies between biological and cultural evolution and, in particular, that cultural items do exhibit variation, competition, and cumulative modification. On the other hand, we believe that a proper understanding of the mechanisms of cultural propagation drawing on the work of cognitive and social scientists (see Sperber and Hirschfeld 1999 for a review) contradicts the idea that culture exhibits inheritance in the strict sense needed for the theory of evolution by natural selection to apply straightforwardly to it. If so, it will take more than adjusting the Darwinian model to be faithful to the Darwinian inspiration. (shrink)

The question of monogenesis vs. polygenesis of human languages was essentially neglected by contemporary linguistics until the appearance of the research on the genetics of human populations by L. L. Cavalli-Sforza and his collaborators, which brought to light very exciting parallels between the distribution of human populations and that of language families. The present paper highlights some aspects of the history of the problem and some points of the contemporary discussion. We first outline the “Biblical paradigm”, which persisted (...) until the 18th century even in scientific milieus. Then, we outline some aspects of the 19th century debate about monogenesis vs. polygenesis of languages and about the relationships between languages and human populations: in particular, we will discuss the views of Darwin on the one hand and of some linguists on the other (Schleicher, M. Müller, Whitney and Trombetti). It will be seen that their positions only partly coincide; at any rate, it will be shown that Darwin was partly inspired by the problems of the genealogy of languages and that the linguists, for their part, took account of Darwin’s views. Turning to today’s debate, we first present the positions of the linguists arguing for monogenesis, namely J. Greenberg and M. Ruhlen, as well as the criticisms raised against their methods by the majority of linguists. Other scholars, such as D. Bickerton or N. Chomsky, essentially argue, from different points of view, that the problem of monogenesis vs. polygenesis of languages is a “pseudo-problem”. We however think that, although the question cannot be reasonably solved by linguistic means, it cannot be discarded as meaningless: it is an anthropological rather than a linguistic problem. We present some reflections and suggestions, in the light of which the monogenetic hypothesis appears as more tenable than the polygenetic one. (shrink)

Species evolve, very slowly, through selection of genes which give rise to phenotypes well adapted to their environments. The cultures, including the languages, of human communities evolve, much faster, maintaining at least a minimum level of adaptedness to the external, non- cultural environment. In the phylogenetic evolution of species, the transmission of information across generations is via copying of molecules, and innovation is by mutation and sexual recombination. In cultural evolution, the transmission of information across generations is by learning, and (...) innovation is by sporadic invention or borrowing from other cultures. This much is the foundational bedrock of evolutionary theory. But things get more complicated; there can be gene-culture co-evolution. Prior to the rise of culture, the physical environment is the only force shaping biological evolution from outside the organism, and cultures themselves are clearly constrained by the evolved biological characteristics of their members. But cultures become part of the external environment, and influence the course of biological evolution. For example, altruistic cultures with developed medical knowledge reduce the cost to the individual of carrying genes disposing to certain pathologies (such as diabetes); and such genes become more widespread in the populations maintaining such cultures. Assortative mating can affect biological evolution, and particular cultures may influence the factors which are sorted for in mating. (For a careful discussion of the effects of cultural evolution on natural selection, see Cavalli-Sforza and Bodmer, 1971:774- 804). This paper examines mechanisms involved in the co-evolution of a biological trait, the critical period for language acquisition, and a property of human cultures, the size of their languages. A gene/culture interaction will be shown that can be described as a kind of symbiosis, but perhaps more aptly as an `arms race'. In this introduction, we will sketch the basic mechanics of the interaction in very broad terms; the rest of the paper will explain and justify the details. The implications of our model for second language acquisition are given toward the end of the paper. (shrink)

Since the first phase of the formal effort to sequence the human genome, geneticists, social scientists and other scholars of race and ethnicity have warned that new genetic technologies and knowledge could have negative social effects, from biologizing racial and ethnic categories to the emergence of dangerous forms of genetic discrimination. Early on in the Human Genome Project, population geneticists like Luigi Luca Cavalli-Sforza enthusiastically advocated for the collection of DNA samples from global indigenous populations in order to (...) track the history of human ancestry, migration, and languages, while social scientists like Troy Duster insisted that the new genetics was in danger of ushering in insidious practices of eugenics. The Human Genome Diversity Project's 1991 proposal to archive human genetic variation around the world quickly came under intense scrutiny by indigenous peoples and advocacy groups who worried that such measures could exploit indigenous groups as research populations and even resurrect racist taxonomies from the nineteenth century.

Italian Life sciences in post-WWII faced important challenges: the reconstruction of a scientific panorama suffering heavily after two decades of Fascism and the damages of war. Modernization was not only a matter of recreating a favorable environment for research, by modernizing Italian biomedical institutions and connecting the Italian scientists with the new ideas coming from abroad. The introduction of new genetics required a new array of concepts and instruments, but also, the ability to connect to international networks and to become (...) active members of a broader scientific community. Because of the several socio-cultural issues involved (eugenics, racism, religion, politics), human genetics is a good case study in order to analyze how Italian life sciences managed the transition towards a new research system, and the influences Italian human geneticists received. The paper focuses primarily on the development of the early career of Luigi Luca Cavalli-Sforza, probably the most prominent scientist in post-WWII human genetics in Italy, and his friend and colleague Ruggero Ceppellini. In following their path, a healthy mix of local traditions and international stimuli emerges, allowing for the establishment—within and beyond national borders—of the discipline. (shrink)

Four theoretical monographs, written by biologists in the wake of the sociobiology debate, and which treat, or purport to treat, the topic of sociocultural evolution are examined in this paper. On the biosocial spectrum they range from Trivers' pure sociobiology, to Lumsden and Wilson's sociobiology "in drag," to Boyd and Richerson's genuinely dual approach, to Cavalli-Sforza and Feldman's purely cultural transmission and evolution. The latter is likely to prove of greatest interest to social scientists and represents a major (...) advance in theorizing mathematically about social change. While the most comprehensive, Boyd and Richerson's "dual inheritance" model ultimately places more emphasis on the biological evolution of the capacity for culture than on genuine gene/culture coevolution even though it is conceivable that cultural transmission and evolution could be providing the selective force responsible for some fundamental biological phenomena such as sexual reproduction in long-lived vertebrates for example. The relationship between contemporary evolutionary and non-evolutionary theories of social change is not dealt with here but the former are very relevant to the latter because evolutionists believe they have available sophisticated solutions to problems which continue to plague other theoretical traditions.

Nella prefazione del suo libro L’evoluzione della cultura (2004), il genetista italiano Luigi Luca Cavalli-Sforza scriveva: «L’evoluzione della cultura è un argomento che ha stranamente ricevuto pochissima attenzione […] Spero che quest’operetta aiuti a suscitare l’interesse che l’argomento merita e che dia vita completamente nuova a una scienza che in America sta morendo e in Europa non ha mai fatto molta strada, l’antropologia culturale, e convinca della necessità di un approccio multidisci...

In lieu of an abstract, here is a brief excerpt of the content:Humanism and Truth: Valla Writes against the Donation of ConstantineRiccardo FubiniTranslated by Anastasia Ananson and William ConnellThere has existed for a long time now in studies of Renaissance humanism (and not only as these have developed in a single country or disciplinary area) a tendency to consider from a prevalently formalist point of view what was instead an innovative and complex cultural experience. A particularly privileged position has been (...) reserved for the ars rhetorica, which, considered in its “purely formal instrumentality,” has been treated as though immune from ideological contamination. 1 The fear of becoming entangled in matters of ideological interpretation may, in turn, give rise to new and more seriously flawed readings. Although this is a matter which I shall not now emphasize, it should be clear that when the interpretation of a text is limited to its “purely formal instrumentality,” the vacuum that results can be filled more easily with matter that is new and different. Ideology chased from the doorstep may yet sneak in through the window, sometimes completely stripped of its real historical context. However, what is more important to note here as a premise to my discussion is that, along with the formalism already referred to, one finds in recent studies a tendency to diminish or minimize the significance of writings that were celebrated by the historical traditions of the last century and felt to belong to a shared cultural, religious, or political legacy.Among such writings the De falso credita et ementita Constantini donatione of Lorenzo Valla has certainly played an important part, beginning at least with the clamor that was raised on its behalf by Ulrich von Hutten and Martin Luther. Yet it is quite typical that the work’s most recent [End Page 79] editor, who has dedicated much careful research to Valla’s treatise and its reception, should have attempted to disconnect the meaning of Valla’s treatise in its own time from the influence it would later have, concluding that “the influence [of Valla’s work] manifested itself in accents quite different from those that have resulted from [current] interpretation.” 2 In the view of this scholar, at the time of the composition of Valla’s work, Constantine’s alleged “donation” was no longer a matter of contemporary relevance; rather, it furnished the theme for a brilliant exercise in legal rhetoric. He writes: “By then the Donation of Constantine was no longer an urgent theme for political theory. (Die Konstantinische Schenkung war damals kein beherrschendes Thema der politischen Theorie mehr.)” 3My discussion takes its cue from this point. Without dwelling at length on the various contributions of other scholars, I shall begin first by trying, on the basis of documentary evidence, to restore Valla’s treatise to life, to the climate of its day, in order then to gather and present its meaning along interpretative lines I have already laid out elsewhere. 4According to that usually trustworthy Florentine chronicler, Giovanni Cavalcanti, Filippo Maria Visconti, duke of Milan, at the end of 1443 made a diplomatic avance toward Florence. Principal among the issues dividing the two powers had been the protection afforded by the regime of Cosimo de’ Medici to Francesco Sforza, then holed up in his fiefdoms in the March of Ancona. The Duke now proposed that they should unite in common defense against the Pope, insofar as the latter was sovereign lord of the March. Beyond these particular circumstances, the accord was supposed to find its warrant in the partners’ shared interest in affirming the superiority of civil over ecclesiastical jurisdiction. So the Duke, according to Cavalcanti, advanced his proposal with words that allow us to suspect an early but not surprising echo of Valla’s treatise (first circulated in that very year): “It so happens that even if Constantine consigned to Sylvester so many and such rich gifts—which is doubtful, because such a privilege can nowhere be found—he could only have granted them for his [Sylvester’s] lifetime, [because] the Empire takes precedence over any lordship.” No differently from Valla, Duke Filippo Maria thought the sovereign impersonality of the [End Page 80] law was the prerogative only of the Empire (and...

Peirce considered the principal business of logic to be the analysis of reasoning. He argued that the diagrammatic system of Existential Graphs, which he had invented in 1896, carries the logical analysis of reasoning to the furthest point possible. The present paper investigates the analytic virtues of the Alpha part of the system, which corresponds to the sentential calculus. We examine Peirce’s proposal that the relation of illation is the primitive relation of logic and defend the view that this idea (...) constitutes the fundamental motive of philosophy of notation both in algebraic and graphical logic. We explain how in his algebras and graphs Peirce arrived at a unifying notation for logical constants that represent both truth-function and scope. Finally, we show that Shin’s argument for multiple readings of Alpha graphs is circular. (shrink)

The deep comprehension of a text is tantamount to the construction of an articulated mental model of that text. The number of correct recollections is an index of a learner's mental model of a text. We assume that another index of comprehension is the timing of the gestures produced during text recall; gestures are simultaneous with speech when the learner has built an articulated mental model of the text, whereas they anticipate the speech when the learner has built a less (...) articulated mental model. The results of four experiments confirm the predictions deriving from our assumptions for both children and adults. Provided that the recollections are correct, the timing of gestures can differ and can be considered a further measure of the quality of the mental model, beyond the number of correct recollections.

Research indicates that religious values and ethical behavior are closely associated, yet, at a firm level, the processes by which this association occurs are poorly understood. Family firms are known to exhibit values-based behavior, which in turn can lead to specific firm-level outcomes. It is also known that one’s family is an important incubator, enabler, and perpetuator of religious values across successive generations. Our study examines the experiences of a single, multigenerational business family that successfully enacted their religious values in (...) their business. Drawing upon intergenerational solidarity and values-based leadership theory, and by way of an interpretive, qualitative analysis, we find that the family’s religious values enhanced their cohesion and were manifested in their leadership style, which, in turn, led to outcomes for the business. Our findings highlight the processes that underlie the relationship between religious values and organizational outcomes in family firms and offer insights into the role of solidarity in values-based leadership.

Deepfake technology can be used to produce videos of real individuals, saying and doing things that they never in fact said or did, that appear highly authentic. Having accepted the premise that Deepfake content can constitute a legitimate form of expression, it is not immediately clear where the rights of content producers and distributors end, and where the rights of individuals whose likenesses are used in this content begin. This paper explores the question of whether it can be plausibly argued (...) that Deepfake content involving the likenesses of real individuals violates the rights of these individuals. (shrink)

Modal Meinongianism is the most recent neo-Meinongian theory. Its main innovation consists in a Comprehension Principle which, unlike other neo-Meinongian approaches, seemingly avoids limitations on the properties that can characterize objects. However, in a recent paper A. Sauchelli has raised an objection against modal Meinongianism, to the effect that properties and relations involving reference to worlds at which they are instantiated, and specifically to the actual world or parts thereof, force a limitation of its Comprehension Principle. The theory, thus, is (...) no better off than other neo-Meinongian views in this respect. This article shows that the notion part of actuality in Sauchelli’s paper is ambiguous from the modal Meinongian viewpoint. Accordingly, his objection splits into two, depending on its disambiguation. It is then explained how neither interpretation forces modal Meinongianism to limit its Comprehension Principle. A third problem connected to Sauchelli’s objection is addressed: how to account for our felicitously referring to nonexistent objects via descriptions that embed reference to properties not actually instantiated by the objects. Overall, the replies to these difficulties provide good insights into the workings of the new Meinongian theory. (shrink)

This paper argues that Umberto Eco had a sophisticated theory of abductive reasoning and that this theory is fundamentally akin to Peirce’s both in the analysis and in the justification of this kind of reasoning. The first section expounds the essentials of Peirce’s theory of abduction, and explains how Peirce moved from seeing abduction as a kind of reasoning to seeing it as a stage of the larger process of inquiry. The second section deals with one of Eco’s paradigmatic examples (...) of abduction, i.e., William of Baskerville’s abduction concerning the horse Brunellus in the overture of The Name of the Rose, and shows that, just like in Peirce’s three-stages model of inquiry, William’s abductions are verified by means of deduction and induction. The third section examines the problem of the justification of abductive reasoning, and argues that both Peirce and Eco solved this problem through the idea that the justification of abduction is itself abductive (meta-abduction in Eco, ur-abduction in Peirce).

In Soph. 237b7–239a11 Plato lays out a sequence of arguments that are generally considered homogenous. An analysis of each argument can shed light on the need to differentiate their respective nature. Firstly, it will be shown that the arguments do not work only at the linguistic level, contrary to the way these passages are interpreted by most of commentators. The meta–linguistic nature of the third argument will be particularly emphasised. Secondly, it will be argued that the three arguments follow each (...) other according to a crescendo. The implications of this argumentative structure will be specifically appreciated. Both these results of the analysis induce to attribute a crucial importance to the notion of medamos on: the arguments do not aim to definitively exclude the possibility of a Parmenidean non–being; they play a positive role within the inquiry of the Stranger of Elea, inasmuch the thematisation of Parmenidean non–being is seriously taken into account and embraced at this stage of the dialogue. In fact it is only through this dialectical step that the Stranger gains the chance to proceed in the direction of a relational ontology and a new concept of non–being. The positive role played by the medamos on presupposes that this expression and the equivalent ones are not mere absurdities and can find place in the Platonic use of language; this implies that the notion of medamos on must have a justification in the framework of Platonic relational ontology and conception of language. The consideration of this aspect eventually gives the opportunity to return to the three arguments and present an explanation of their positioning in that stage of the dialogue. (shrink)
