Peace is a hallmark of human societies. However, certain ant species engage in long-term intergroup resource sharing, which is remarkably similar to peace among human groups. We discuss how individual and group payoff distributions are affected by kinship, dispersal, and age structure; the challenges of diagnosing peace; and the benefits of comparing convergent complex behaviours in disparate taxa.

This paper analyzes the specific shift in the meaning of “civilization” that took place in texts and documents of early American philosophical naturalism. Particularly, it will focus on the specific role that naturalization plays in the edification of a newly secularized, science-oriented, and democratic society, as well as of a naturalized conception of culture and civilization. Indeed, as the work of many philosophers and intellectuals of the Forties highlights, naturalism represents not only the banner of a new idea of civilization, (...) but at the same time becomes the symbol of a powerful postwar ideology.

The recent pandemic and consequent lockdown had a substantial impact on mental health and optimism regarding the future. Previous research showed that levels of depression, anxiety, and stress had increased throughout the pandemic. Nonetheless, how individuals cope when faced with adversity may be associated with positive expectations regarding the future. A sample of 274 Portuguese workers with a mean age of 40.86 and work experience of 19.68 years met inclusion criteria and agreed to participate in the proposed study. They represented (...) a variety of working classes. We investigated the associations between depression, stress, anxiety, adaptive and maladaptive coping, and optimism while controlling for working experience, gender, and work type. We found that depression was related to lower levels of optimism. However, for participants scoring high on adaptive coping and anxiety, higher scores of optimism were reported. Gender, work type, and experience did not significantly influence the results. These results provide evidence through which positive mental health can be promoted after the pandemic. (shrink)

Trustful and trustworthy behaviors have important externalities for the society. But what exactly drives people to behave in a trustful and trustworthy manner? Building on research suggesting that individuals’ social preferences might be a common factor informing both behaviors, we study the impact of a set of different motives on individuals’ choices in a dual-role Trust Game (TG). We employ data from a large-scale representative experiment ( N = 774), where all subjects played both roles of a binary TG with (...) real monetary incentives. Subjects’ social motives were inferred using their decisions in a Dictator Game and a dual-role Ultimatum Game. Next to self-interest and strategic motives we consider preferences for altruism, spitefulness, egalitarianism, and efficiency. We demonstrate that there exists considerable heterogeneity in motives in the TG. Most importantly, among individuals who choose to trust as trustors, social motives can differ dramatically as there is a non-negligible proportion of them who seem to act out of (strategic) self-interest whereas others are driven more by efficiency considerations. Subjects’ elicited trustworthiness, however, can be used to infer such motivations: while the former are not trustworthy as trustees, the latter are. We discuss that research on trust can benefit from adding the second player’s choice in TG designs. (shrink)

This paper develops the very basic notions of analysis in a weak second-order theory of arithmetic BTFA whose provably total functions are the polynomial time computable functions. We formalize within BTFA the real number system and the notion of a continuous real function of a real variable. The theory BTFA is able to prove the intermediate value theorem, wherefore it follows that the system of real numbers is a real closed ordered field. In the last section of the paper, we (...) show how to interpret the theory BTFA in Robinson's theory of arithmetic Q. This fact entails that the elementary theory of the real closed ordered fields is interpretable in Q. (shrink)

Given an argumentation network with initial values to the arguments, we look for algorithms which can yield extensions compatible with such initial values. We find that the best way of tackling this problem is to offer an iteration formula that takes the initial values and the attack relation and iterates a sequence of intermediate values that eventually converges leading to an extension. The properties surrounding the application of the iteration formula and its connection with other numerical and non-numerical techniques proposed (...) by others are thoroughly investigated in this paper.

There is a generic way to add any new feature to a system. It involves identifying the basic units which build up the system and introducing the new feature to each of these basic units. In the case where the system is argumentation and the feature is probabilistic we have the following. The basic units are: the nature of the arguments involved; the membership relation in the set S of arguments; the attack relation; and the choice of extensions. Generically to (...) add a new aspect to an argumentation network \ can be done by adding this feature to each component. This is a brute-force method and may yield a non-intuitive or meaningful result. A better way is to meaningfully translate the object system into another target system which does have the aspect required and then let the target system endow the aspect on the initial system. In our case we translate argumentation into classical propositional logic and get probabilistic argumentation from the translation. Of course what we get depends on how we translate. In fact, in this paper we introduce probabilistic semantics to abstract argumentation theory based on the equational approach to argumentation networks. We then compare our semantics with existing proposals in the literature including the approaches by M. Thimm and by A. Hunter. Our methodology in general is discussed in the conclusion. (shrink)

We prove two conservation results involving a generalization of the principle of strict ${\Pi^1_1}$ -reflection, in the context of bounded arithmetic. In this context a separation between the concepts of bounded set and binary sequence seems to emerge as fundamental.

The emerging field of neuroeducation, concerned with the interaction between mind, brain and education, has proved revolutionary in educational research, introducing concepts, methods, and technologies into many advanced institutions around the world. The Educated Brain presents a broad overview of the major topics in this new discipline: Part I examines the historical and epistemological issues related to the mind/brain problem and the scope of neuroeducation; Part II provides a view of basic brain research in education and use of imaging techniques, (...) and the study of brain and cognitive development; and Part III is dedicated to the neural foundations of language and reading in different cultures, and the acquisition of basic mathematical concepts. With contributions from leading researchers in the field, this book features the most recent and advanced research in cognitive neurosciences. (shrink)

Aim of this work is to dispel the myth of the "vagueness" of naturalism. Between the Thirties and the Forties, naturalism moves “from old Europe to dynamic America” (as the historian Larrabee said). The controversy with visionary and fascist European theories was indeed very strong in the academic culture of the Thirties and Forties. The idea was to oppose to the former the virtue of a liberal democracy, supported by the liberality of the scientific method.In short, the cultural fight was (...) between naturalism and metaphysics (considered as theology). Naturalizing the "spirit" was the great ambition of American naturalistic programs of the Forties. They culminated with the publication of the ideological manifesto “Naturalism and the Human Spirit” (New York, 1944), edited by the John Dewey's group of Columbia. From Ernest Nagel to Sydney Hook, Roy Wood Sellars, William Sheldon and Arthur E. Murphy, all prominent American philosophers took part, in one way or another, to the naturalistic project. This latter aimed to be more than a simple "doctrine", by presenting itself as an expression of a new “mental attitude”, a fresh way of considering traditional unsolved problems. All this lead to the production of a new form of rhetoric, which in turn carried with itself a hidden ideology. Objective rationality embodied by scientific procedures became the totem to play against everything that would present itself as “just-subjective”, metaphysical, all-encompassing. A new idea of philosophy began to emerge, one that was less metaphysical, more humanistic and democratic, and concerned itself with “restricted, but manageable questions” (E. Nagel). (shrink)

Vertebrates respond to light with more than just their eyes. In this article, we speculate on the intriguing possibility that a link remains between non‐visual opsins and neurohormonal systems that control neuronal circuit formation and activity in mammals. Historically, the retina and pineal gland were considered the only significant light‐sensing tissues in vertebrates. However over the last century, evidence has accumulated arguing that extra‐ocular tissues in vertebrates influence behavior through non‐image‐forming photoreception. One such class of extra‐ocular light detectors are the (...) long mysterious deep brain photoreceptors. Here, we review recent findings on the cellular identity and the function of deep brain photoreceptors controlling behavior and physiology in zebrafish, and discuss their implications. (shrink)

In this paper, I would like to focus upon two things. The first concerns the intertwining of naturalism and religion, namely the fact that early American naturalism defined itself as a “secular religion”. This expression sounds like an oxymoron, but the analysis of a dazzling text by Francis Ellingwood Abbot will help us to clarify the concept of “godless religion”, which will be taken up in the following years by all the major naturalists of the time. The second concerns the (...) power of the symbolic dimension of naturalism, especially in the debates of the 1940s. In those years naturalism was engaged in a battle for the survival of democracy. “Science”, “democracy” and “freedom” were not only concepts debated on a theoretical level, but they outlined a system of archetypes by virtue of which post-war liberal and democratic America would build a relevant part of its self-image.

Este artículo afronta el concepto de “laicidad”. El primer paso es clarificar los distintos términos y sobre todo los conceptos que se usan en este argumento. Después se hace un recorrido por la historia del cristianismo sobre la laicidad, comenzando por el comportamiento del mismo Jesús. En la Iglesia se fue pasando de esta situación a la más rígida sacralización del cristianismo hasta convertirlo en una verdadera “religión”, aunque por encima de todas las demás. En este camino, después de siglos, (...) el Concilio Vaticano II ha superado la situación anterior de sociedad sacralizada, a la distinción y separación neta entre el plano social y el plano eclesial. Este cambio lleva a consecuencias claras y concretas tanto de puertas adentro de la Iglesia, como en su relación con la sociedad laica en que vive la propia institución eclesial como cada cristiano personalmente.

Partiendo de la invitación hecha por el Papa Juan Pablo II en su Carta Apostólica "Tertio Millennio Adveniente" a reflexionar sobre la estrecha relación existente entre los misterios de la Encarnación y de la Eucaristía (perspectiva central del Jubileo 2000: TM 55), este trabajo estudia en profundidad las claves bíblicas y teológicas desde las que estos dos misterios que se pueden ver y considerar. Entre las muchas claves desde las que sería posible leer e interpretar estos misterios, este trabajo ha (...) seleccionado seis de ellas, que perfectamente aplicables a ambos misterios, y que constituyen el hilo conductor de la presente reflexión: el trinitario, el pascual, la unidad, la presencia mutuamente vinculante y redentora, la plenitud y las claves marianas.

The word “organism” represents an original keyword of the early-modern philosophical world. As it was first developed by Leibniz, it seems to blend together two different conceptual paradigms: the Cartesian model of the “machines” and the Aristotelian legacy of the “individual natures”. According to the first, nature represents itself the prototype of any good mechanical functioning, but at the same time its inner development is explained by the occurrence of a normative dimension that rules the world of primitive forces in (...) the dynamics. For such reasons, the “organism” lexicon is affected by an internal stress that is extremely interesting to analyze for it seems to posit a normative turn acting from the within of a mechanically conceived notion of life.

What kind of relationship subsists between an “organism” and a “monas dominans »? In some texts, Leibniz claims that the soul « actuat » the organic body and in the late debate with Stahl he describes the « monas dominans » as a « monas actuatrix ». But how does the monas « actualize » the organic body ? and what implies the semantic of the word « agere » here used by Leibniz ? Is it also possibile to describe (...) this event in terms of « whole/part » relationship ? The aim of this paper is to sketch out the status quaestionis of the topic by discussing some of the most recent studies. More specifically to propose an interpretation of the « monas dominans » as the « nota distinguens » of the whole organism. (shrink)

It is certainly true that in early modern thought the emergence of a new science changed the image of the universe in a mechanistic way. It must be considered, though, that most of the main protagonists of this revolution (Kepler, Newton, Leibniz, ‘biologists’ like Leeuwenhoek, Hartsoeker, Hooke, Malpighi, Redi, etc.) still continued to consider the importance and the utility of a finalistic explanation of natural phenomena. Concepts like “function”, “self-organization”, “organism” have roots in early modern thought: not only from a (...) linguistic and semantic point of view. They were the basis of an epistemology in which different kinds of categories are strictly related. The aim of the paper is to take into account the relevance of the mechanical explanation of natural phenomena in Leibniz’s thought and at the same time to highlight the polarization between mechanical explanations and finalistic consideration that emerges in his philosophy. The specific aim of the paper is to analyze and to develop this kind of dialectic between “teleology” and "mechanism", with particular reference to the concept of “living being”. (shrink)

The aim of this paper is twofold. First, I would like to bring into the light the almost unexplored Sellars’s theory of particulars. Second, I would like to show its surprising degree of compatibility with the thesis supported by some contemporary tropists, Tropes, Universals and the Philosophy of Mind, Ontos Verlag, 2008; Moltmann, Mind 113:1–41, 2004 and Moltmann, Noûs 47:346–370, 2013). It is difficult to establish whether Sellars possessed an own theory of tropes, developed independently by the classical form it (...) took in Williams 1953, but as a matter of fact the peculiar features of his “complex particulars” model it is very much like Williams’s theory. So much so that to all intents and purposes it represents a tropes variation. One of its strengths is that it is not part of a constituent ontology, since it is essentially developed from a linguistic and phenomenological point of view. It is for these reasons that this theory manages to avoid some of the classic objections to tropes and it shows to be compatible with the argument of Jonathan Lowe’s “proper visibility” as well as with Friederike Moltmann’s exquisitely linguistic interpretation of tropes.

Abordamos en este trabajo la imagen de Dios que nos revela el cántico evangélico del Magnificat (Lucas 1, 46-55) y la imagen de María que en él aparece. Partiendo de su contexto en la obra de Lucas y de un breve análisis exegético del cántico, los autores profundizan en sus claves teológicas en relación con dos núcleos: la imagen de Dios y la figura de María introducida por el evangelista. El trabajo concluye con una propuesta de relectura del Magnficat acorde (...) con nuestro tiempo, centrada en su dimensión profética y liberadora. (shrink)

Ion channels are transport proteins present in the lipid bilayers of biological membranes. They are involved in many physiological processes, such as the generation of nerve impulses, hormonal secretion, and heartbeat. Conformational changes in the ion channel-forming protein allow the opening or closing of pores to control the ionic flux through the cell membranes. The opening and closing of the ion channel have been classically treated as a random kinetic process, known as a Markov process. Here the time the channel (...) remains in a given state is assumed to be independent of the condition it had in the previous state. More recently, however, several studies have shown that this process is not random but a deterministic one, where both the open and closed dwell-times and the ionic current flowing through the channel are history-dependent. This property is called long memory or long-range correlation. However, there is still much controversy regarding how this memory originates, which region of the channel is responsible for this property, and which models could best reproduce the memory effect. In this article, we provide a review of what is, where it is, its possible origin, and the mathematical methods used to analyze the long-term memory present in the kinetic process of ion channels.

Usually scholars think of Marvin Farber as an American pupil of Husserl and his figure is given historical and institutional credit. It is also said that his thought misrepresented the intentions of the master and that his idea of a naturalization of phenomenology was devoid of hermeneutical grounds. All this has fed the myth of his heresy, the idea that his philosophical proposal could be summarized as a deviation from the orthodox canon. In this paper the legitimacy of this perspective (...) is widely discussed. Is it really correct to think of him as a child of the phenomenological continental tradition transplanted on American soil? Or would it not be more fruitful to consider him, beyond the canon, as an American philosopher fully immersed in the epistemological debates of his time? The paper argues in favor of this way of interpretation, discussing Farber’s own theoretical proposal in conjunction with the ecosystem of the American philosophical history. (shrink)

Este trabajo consiste en una reconstrucción de los motivos de reflexión en ese ámbito privilegiado de la experiencia filosófica al que de la mano de Habermas, vamos a denominar pensamiento postmetafísico, como superación mediadora de la eterna disputa entre el pensar metafísico y el pensar antimetafísico. En él desarrollaremos aquellas categorías empírico-trascendentales que van a constituir las condiciones de posibilidad de esta nueva experiencia filosófica, a saber, racionalidad procedimental, razón sin trascendencia, razón comunicativa, giro lingüístico y deflación de lo extracotidiano.

Knowledge and true relations represent the principal task of Theory of Knowledge. This paper argues about various solutions to the justification of knowledge, given by William James, Richard Rorty and Jürgen Habermas. For classic Pragmatism Knowledge and Truth converge with the idea of a guideline, direction and orientation with an effective value for men. The Newpragmatism represented by Rorty tries out the way of the widest possible widening of justification contexts, taking as last referent the features of a western liberal (...) culture. Habermas pleads for a strong idealization in his discussion with Rorty up to the ideal speech situation. (shrink)

La tesis que deseo discutir en este trabajo es la siguiente: las ciencias humanas (ciencias del espíritu según Dilthey, ciencias histórico-hermenéuticas según Habermas) son posibles en la medida en que pueda ser epistemológicamente justificado el método que las hace posibles, a saber, la comprensión hermenéutica del sentido cuyo núcleo central lo constituye el círculo hermenéutico. Se trata, pues, de justificar epistemológicamente la hermenéutica como comprensión del sentido de las vivencias propias y ajenas, para lo cual es preciso analizar la reflexividad (...) y reciprocidad que impregna la estructura del lenguaje ordinario. En el diálogo que Habermas establece con Dilthey en Conocimiento e interés aparecen los suficientes argumentos para dicha fundamentación. Nuestro texto hará especial hincapié en los siguientes tópicos: distinción entre ciencias de la naturaleza y ciencias del espíritu, comprensión hermenéutica del sentido, lenguaje ordinario y reflexividad, especificidad del círculo hermenéutico, ciencia y contexto vital, y, finalmente, haremos un balance de la interpretación habermasiana de Dilthey a partir de las relaciones entre ciencias histórico-hermenéuticas e interés práctico del conocimiento.
