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)

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)

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...

A thriving literature has developed over logical and mathematical pluralism – i.e. the views that several rival logical and mathematical theories can be equally correct. These have unfortunately grown separate; instead, they both could gain a great deal by a closer interaction. Our aim is thus to present some novel forms of abstractionist mathematical pluralism which can be modeled on parallel ways of substantiating logical pluralism (also in connection with logical anti-exceptionalism). To do this, we start by discussing the Good (...) Company Problem for neo-logicists recently raised by Paolo Mancosu (2016), concerning the existence of rival abstractive definitions of cardinal number which are nonetheless equally able to reconstruct Peano Arithmetic. We survey Mancosu’s envisaged possible replies to this predicament, and suggest as a further path the adoption of some form of mathematical pluralism concerning abstraction principles. We then explore three possible ways of substantiating such pluralism—Conceptual Pluralism, Domain Pluralism, Pluralism about Criteria—showing how each of them can be related to analogous proposals in the philosophy of logic. We conclude by considering advantages, concerns, and theoretical ramifications for these varieties of mathematical pluralism. (shrink)

The present study aimed to verify the quarantine’s effects during a serious viral outbreak on the cardiovascular and performance associated with the Yo-Yo test in a sample of professional soccer players. 20 high-level soccer players participated in this study. The intermittent Yo-Yo test was performed pre- and post- COVID-19 quarantine in a random order. During each test, the soccer players’ running performance outcomes were monitored using a portable 5-Hz GPS with a 100 Hz accelerometer and a paired t-test was conducted (...) at a p-value of ≤ 0.05. The main results demonstrated significant differences between pre- versus post-COVID-19 quarantine in the following variables: relative distance, maximal speed, acceleration, deceleration, sprints > 19 km/h [0.8 % >0.5 %], and in high intensity running distance [16.48 m > 0.827 m]. We concluded that COVID-19-related restrictions and quarantine COVID-19 demonstrated adverse effects on professional soccer players’ Yo-Yo tests performance. (shrink)

First collected in Italy in 1985, _Art's Claim to Truth_ is considered by many philosophers to be one of Gianni Vattimo's most important works. Newly revised for English readers, the book begins with a challenge to Plato, Aristotle, Kant, and Hegel, who viewed art as a metaphysical aspect of reality rather than a futuristic anticipation of it. Following Martin Heidegger's interpretation of the history of philosophy, Vattimo outlines the existential ontological conditions of aesthetics, paying particular attention to the works of (...) Kandinsky, which reaffirm the ontological implications of art. Vattimo then builds on Hans-Georg Gadamer's theory of aesthetics and provides an alternative to a rationalistic-positivistic criticism of art. This is the heart of Vattimo's argument, and with it he demonstrates how hermeneutical philosophy reaffirms art's ontological status and makes clear the importance of hermeneutics for aesthetic studies. In the book's final section, Vattimo articulates the consequences of reclaiming the ontological status of aesthetics without its metaphysical implications, holding Aristotle's concept of beauty responsible for the dissolution of metaphysics itself. In its direct engagement with the works of Gadamer, Heidegger, and Luigi Pareyson, _Art's Claim to Truth_ offers a better understanding of the work of Vattimo and a deeper knowledge of ontology, hermeneutics, and the philosophical examination of truth.

We reedit in the dossier of this issue an essay of Luigi Luzzatti first came out in «Nuova Anthologia» in 1880. In it Luzzatti rereads the British constitutional history thanks to a set of biological metaphors and analogies, which are analyzed and historically framed in the introduction of Luca Ciancio. This approach of Luzzatti further enhances the reconstruction of history of Constitutions he offers analyzing the works of the greatest historians of his time.

Luca Ciancio discusses Luigi Luzzatti’s article starting from a reflection about the ubiquity of the biological metaphors used by him in order to reason on the method of constitutional science. Luzzatti bases on the classic distinction between historic "organic" constitutions, i.e. the British one, which is a true and spontaneous incarnation of the "national character", and abstract "mechanic" constitutions, artificially imposed by reason and therefore instable. In the late positivistic era the same recourse to a metaphorical evolutionistic repertoire, (...) like the one of the embryologic dynamic of the constitutions, on the one defines hand Luzzatti’s intent as a subscription to historicism and organicism, which is typical of his epoch, and on the other hand the free recourse to biology allows him to discuss cognitive strategies that are useful to constitutional science and freed from a dogmatic notion of scientificity. Through Luzzatti's text, though, Ciancio underlines the meaning and the function of an evolutionistic paradigm which defined in a rigid and ideological way the historic investigation and which Luzzatti uses to recall an idea of order, restoration and continuity.

Il breve saggio si propone di esaminare la centralità della figura materna nell’opera di un ingegnoso costruttore di storie della letteratura italiana del Novecento: Alberto Moravia. La scelta dell’Autore nasce dalla rilevanza della tematica nella sua opera, in cui peraltro è quasi sempre assente il punto di vista femminile delle “voci” delle donne. Ciò sembra paradossale e questa circostanza è di grande interesse critico. In particolare, a dispetto delle interpretazioni più canoniche, secondo cui Moravia – negli scritti realizzati tra il (...) 1929 e il 1964 – ha inteso compiere una “distruzione” dell’immagine materna nel quadro di una visione pessimista della famiglia borghese, dovremo considerare un più complesso e articolato universo materno nello scrittore romano, in cui è possibile ricostruire cinque modelli – la “madre autoritaria”, la “madre-non madre”, la “madre padrona”, la “madre-angelo custode” e la “madre-seduttrice” –, ben esemplificati nei principali romanzi ma che si ritrovano nei racconti che Moravia scrive ininterrottamente dagli anni Trenta agli anni Sessanta, la cui mole ha determinato, ancor oggi, una mancanza di studi sistematici. In secondo luogo, la tematica della madre sarà esaminata nelle trasposizioni cinematografiche italiane delle opere letterarie di Moravia. Va ricordato che il rapporto dello scrittore con il cinema fu particolarmente intenso. Per un verso, la “settima arte” rivestì un ruolo non secondario nella formazione ed esperienza estetica dell’Autore romano, che al cinema si interessò anche professionalmente nelle vesti di critico cinematografico, a partire dal primo dopoguerra, dapprima, per La nuova Europa e Libera stampa, poi, per L’Europeo e L’Espresso, a cui dobbiamo aggiungere l’attività di saggista per numerose riviste specializzate. Per altro verso, il cinema italiano non solo ha attinto a “mani basse” dall’opera di Moravia per sceneggiature di pellicole, che furono pietre miliari della sua storia. L’elenco dei romanzi e racconti adattati al grande schermo rende conto della grande influenza nella cultura italiana degli anni Cinquanta e Sessanta: La provinciale (1953) di Mario Soldati, La romana (1954) di Luigi Zampa, Peccato che sia una canaglia (1954) di Alessandro Blasetti, Racconti romani (1955) di Gianni Franciolini, La ciociara (1960) di Vittorio de Sica, La giornata balorda (1960) di Mauro Bolognini, Risate di gioia (1960) di Mario Monicelli, Agostino (o la perdita dell’innocenza) (1962) di Mauro Bolognini, La noia (1963) di Damiano Damiani, Gli indifferenti (1964) di Francesco Maselli, Le ore nude (1964) di Marco Vicario, La donna invisibile (1969) di Paolo Spinola, Una ragazza piuttosto complicata (1969) di Damiano Damiani, L’amore coniugale (1970) di Dacia Maraini, Il conformista (1970) di Bernardo Bertolucci, e molti altri ancora. Come avremo modo soltanto di accennare, il successo della letteratura moraviana nel mondo del cinema italiano si deve a molteplici fattori, tra cui la raffigurazione dei personaggi e degli ambienti, la focalizzazione su certe tematiche e, non da ultimo, lo stile narrativo, particolarmente adatto alle trasposizioni cinematografiche. Come caso di studio, ci soffermeremo, infine, sulla figura materna della versione filmica de La noia di Damiani, con l’obiettivo di verificare se nel passaggio dal libro alla pellicola, quella particolare connotazione della madre autoritaria abbia subito delle alterazioni. L’ipotesi che muove l’analisi è che la stesura delle sceneggiature, la raffigurazione dei personaggi e la messa in scena delle sequenze filmiche facciano emergere un riadattamento adeguato al largo pubblico, con il sovvertimento dell’andamento cronologico, alcune “lacune” di ordine psicologico nella raffigurazione dei protagonisti e un certo cedimento moralistico alla cultura ancora dominante negli anni ’50 e ’60, in cui la figura materna, sia quando è incattivita dalla povertà che quando è inaridita dalla ricchezza, anela comunque agli affetti familiari, trovando in essi una qualche forma di redenzione.

This paper offers a critical analysis of two central issues in Luigi Ferrajoli’s Principia iuris , and more generally of his theory of rights. One is the way in which ‘expectations’ play a crucial role in his deontic theory by establishing the logical basis for his guarantee-based conception of law and rights. The axiomatic way in which Ferrajoli arrives at his conception of fundamental rights is questioned, for it fails to give a full account of the nature of subjective (...) rights. The other issues discussed here is Ferrajoli’s own defence of the universality of fundamental rights, and how this is made to depend on a ‘normative technique’ that one can associate with legal discourse and modern law in Western societies. This, however, poses the problem of how this formal universalism can be reconciled with the intercultural dialogue that Ferrajoli also advocates. (shrink)

German MS. 2 is a previously unstudied armorial dating from the mid-sixteenth century. This article shows that it was produced in the workshop of Lucas Cranach the Younger for Elector August of Saxony, and that it was copied from an earlier armorial of c.1500 which was kept in Cranach’s workshop, probably as reference material. Much of the original content and structure of this ‘old armorial’ has been preserved in Rylands German 2. On this basis, the original armorial can be located (...) in a late fifteenth-century Upper German tradition of armorial manuscripts known as the ‘Bodensee’ group. It was also closely linked to the Habsburg dynasty, and appears to have been dedicated to Empress Bianca Maria Sforza. The armorial therefore opens significant new perspectives on the relationships between artists and heraldry and between women and heraldic knowledge, and on ways of visualising the Holy Roman Empire through heraldry.

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.

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)

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.

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.

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)
