Both Medawar and Hamilton contributed key ideas to the modern evolutionary theory of ageing. In particular, they both suggested that, in populations with overlapping generations, the force with which selection acts on traits declines with the age at which traits are expressed. This decline would eventually cause ageing to evolve. However, the biological literature diverges on the relationship between Medawar’s analysis of the force of selection and Hamilton’s. Some authors appear to believe that Hamilton perfected Medawar’s insightful, yet ultimately erroneous (...) analysis of this force, while others see Hamilton’s analysis as a coherent development of, or the obvious complement to Medawar’s. Here, the relationship between the two analyses is revisited. Two things are argued for. First, most of Medawar’s alleged errors that Hamilton would had rectified seem not to be there. The origin of these perceived errors appears to be in a misinterpretation of Medawar’s writings. Second, the mathematics of Medawar and that of Hamilton show a significant overlap. However, different meanings are attached to the same mathematical expression. Medawar put forth an expression for the selective force on age-specific fitness. Hamilton proposed a full spectrum of selective forces each operating on age-specific fitness components, i.e. mortality and fertility. One of Hamilton’s expressions, possibly his most important, is of the same form as Medawar’s expression. But Hamilton’s selective forces on age-specific fitness components do not add up to yield Medawar’s selective force on age-specific fitness. It is concluded that Hamilton’s analysis should be considered neither as a correction to Medawar’s analysis nor as its obvious complement. (shrink)

Paraconsistent Weak Kleene logic is the 3-valued logic with two designated values defined through the weak Kleene tables. This paper is a first attempt to investigate PWK within the perspective and methods of abstract algebraic logic. We give a Hilbert-style system for PWK and prove a normal form theorem. We examine some algebraic structures for PWK, called involutive bisemilattices, showing that they are distributive as bisemilattices and that they form a variety, \, generated by the 3-element algebra WK; we also (...) prove that every involutive bisemilattice is representable as the Płonka sum over a direct system of Boolean algebras. We then study PWK from the viewpoint of AAL. We show that \ is not the equivalent algebraic semantics of any algebraisable logic and that PWK is neither protoalgebraic nor selfextensional, not assertional, but it is truth-equational. We fully characterise the deductive filters of PWK on members of \ and the reduced matrix models of PWK. Finally, we investigate PWK with the methods of second-order AAL—we describe the class \ of PWK-algebras, algebra reducts of basic full generalised matrix models of PWK, showing that they coincide with the quasivariety generated by WK—which differs from \—and explicitly providing a quasiequational basis for it.

In this commentary, I discuss the scientific changes brought by the exposome, asking what is new about this approach and line of research. I place the exposome in a historical perspective, by analyzing the conditions under which the exposome has been conceived, developed and established in the context of contemporary epidemiological research. I argue that the exposome has been developed by transferring approaches, methods and conceptualizations from other lines of research in the life and health sciences. I thus discuss the (...) conceptual and methodological innovations of the exposome as a result of the merging and adaptation of these elements for new uses and purposes. On this basis, I argue that the novelty of the exposome should be seen in incremental rather than revolutionary terms and, in this sense, the exposome shares significant elements with other projects and repertoires in postgenomics. I conclude by discussing the consequences of this analysis for the potential limitations and future development of exposome research. (shrink)

Aim of the paper is contributing to a context-informed understanding of Fichte’s theory of conscience. This crucial element in his moral philosophy (and, in fact, in his whole philosophy) represents the last of the many significant accounts of conscience in the 18th century, before in the following century the role of conscience in moral life was repeatedly put into question. Accordingly, in my paper I argue that: (1) Fichte puts forward an un-Kantian account of conscience, following, instead, a quite different (...) model; (2) Fichte’s views on conscience grew out of a complex conceptual milieu, from which Fichte borrows important (quasi-)sentimentalist elements; (3) Fichte’s idea of the infallibility of conscience must be distinguished from other similar views put forward in the same years.

The goal of this paper is to show that a particular view of emotion sharing and a specific hypothesis on infant social perception strengthen each other. The view of emotion sharing is called “the straightforward view.” The hypothesis on infant social perception is called “the pairing account.” The straightforward view suggests that participants in emotion sharing undergo one and the same overarching emotion. The pairing account posits that infants perceive others’ embodied experiences as belonging to someone other than the self (...) through a process of assimilation to, and accommodation of, their own embodied experience. The connection between the two theories lies in the domain-general process of association by similarity, which functions both in the individuation of a unitary emotion and in the interpretation of the sensory stimulus. By elaborating on this connection, the straightforward view becomes more solid from the cognitive-developmental standpoint and the pairing account expands its explanatory power. Since the straightforward view requires minimal forms of self- and other-awareness, the paper provides a characterization of the developmental origin of the sense of us, i.e., the experience of self and other as co-subjects of a shared emotional state.

We analyze whether companies involved in a security class action suit (SCAS) exhibit differential capital structure decisions, and if the information revealed by a corporate scandal affects the security issuances and stock prices of industry peers. Our findings show that before a SCAS is filed, companies involved in a scandal show a greater amount of security offerings than their peers and, due to equity mispricing, are more likely to use equity as a financing mechanism. Following a SCAS filling, these companies (...) exhibit a decreasing amount of total external finance raised and lower levels of book and market leverage. Industry peers' issuance patterns exhibit significant contagion, with reduced debt and equity issuance following the SCAS filing. Corporate scandals also have meaningful negative effects on stock prices and bond ratings. Similar to capital structure, we document contagion at the industry level with peers' share prices yielding negative returns as well. (shrink)

Philosophical games are games designed to invite players to think philosophically within (and about) their gameworlds. They are interactive fictions allowing players to engage with philosophical themes in ways that often set them apart from non-interactive kinds of speculative fictions (such as philosophical novels or thought experiments). To better understand philosophical games, this entry proposes to distinguish two primary ways in which a philosophical game can approach its themes: dialectically or rhetorically.

We analyze and compare geometrical theories based on mereology (mereogeometries). Most theories in this area lack in formalization, and this prevents any systematic logical analysis. To overcome this problem, we concentrate on specific interpretations for the primitives and use them to isolate comparable models for each theory. Relying on the chosen interpretations, we introduce the notion of environment structure, that is, a minimal structure that contains a (sub)structure for each theory. In particular, in the case of mereogeometries, the domain of (...) an environment structure is composed of particular subsets of Rn. The comparison of mereogeometrical theories within these environment structures shows dependencies among primitives and provides (relative) definitional equivalences. With one exception, we show that all the theories considered are equivalent in these environment structures. (shrink)

We aim to show that far-related primates like humans and the capuchin monkeys show interesting correspondences in terms of artifact characterization and categorization. We investigate this issue by using a philosophically-inspired definition of physical artifact which, developed for human artifacts, turns out to be applicable for cross-species comparison. In this approach an artifact is created when an entity is intentionally selected and some capacities attributed to it (often characterizing a purpose). Behavioral studies suggest that this notion of artifact is not (...) specific to the human kind. On the basis of the results of a series of field observations and experiments on wild capuchin monkeys that routinely use stone hammers and anvils, we show that the notions of intentional selection and attributed capacity appear to be at play in capuchins as well. The study also suggests that functional criteria and contextualization play a fundamental role in terms of artifact recognition and categorization in nonhuman primates. (shrink)

Face aux attitudes passives et violentes de certains jeunes scolarisés, les enseignants expriment de façon permanente la volonté de " rendre les élèves autonomes ". Mais la démarche qui mène à cet objectif est parsemée de pièges. Loin de présupposés non-directifs, cet ouvrage cherche à recenser et à présenter de façon simple l'ensemble des modèles théoriques capables de faire comprendre les processus de modifications d'attitudes de l'élève dans la classe. D'abord vis-à-vis des contenus d'apprentissage, puis vis-à-vis des personnes (le professeur, (...) les autres élèves). Chacun de ces modèles est illustré par des exemples de mises en œuvre en éducation physique. Afin de rendre cohérente l'action du professeur en direction de ces " deux autonomies " (par rapport aux contenus et aux, personnes), la troisième partie de l'ouvrage propose une approche globale qui interprète les conduites observées chez les élèves selon différents niveaux d'intégration des règles dans la situation d'enseignement.

In the middle of the 12th century the traditional core of divination techniques receives some innovation. New techniques appear, one of them particularly successful: chiromancy. It emerges almost simultaneously in Spain and in Plantagenet England, in association with the less fortunate spatulomancy. All six of the vernacular chiromantical texts prior to the 15th century so far recorded are in the langue d’oil and five of the six come specifically from the Anglo-Norman domain. This confirms the Anglo-Norman area as one of (...) the main crossroads of medieval divination, which nevertheless is still awaiting for an overall scholarly treatment, probably due to its linguistical complexity, due to the trilinguistical dynamics Latin/Anglo-Norman/Anglo-Saxon.

En las pocas ocasiones en que Kant aborda el tema de la verdad, lo suele hacer en función de los problemas implicados en la definición nominal de verdad y en la búsqueda de un criterio de verdad. El objetivo de este trabajo es ofrecer una visión sinóptica del modo en que Kant plantea estas dos cuestiones. En la primera sección del trabajo se aborda el tema de la definición de la verdad. Primero explico qué es una definición y qué implica (...) esto para el caso de la verdad. Tras esto, expongo las consecuencias y problemas que Kant extrae al respecto. En la segunda sección del trabajo se desarrolla el tema del criterio de verdad. Para comenzar expongo las expectativas de Kant respecto de dicho criterio y los límites con que se encuentra. Tras esto ofrezco una clasificación y explicación de los criterios de verdad que menciona a lo largo de su obra. (shrink)

In order to appreciate the rich implications of the transcendental reduction, one has to distinguish the different contexts where it acquires different meanings. The present paper focuses on a particular epistemological context and clarifies the contribution of the reduction within this context. The contribution consists in the formulation and solution of the problem of exhibiting the evidence supporting the belief in the world’s existence. In a nutshell, world-experience grounds the world-belief and world-experience entails a bedrock of experience legitimizing the positing (...) of others. I argue that this contribution is possibly an enduring achievement of Husserl’s transcendental philosophy against common objections that are raised against it. I show that both the necessity and the viability of the transcendental reduction are a consequence of the general structure of critical examination. Overall, a picture of Husserl’s philosophy emerges that emphasizes embodiment, intersubjectivity, and facticity without giving up the rigor of radical epistemological analysis, aiming at overcoming both naïve pseudo-problems and subtle forms of dogmatism.

Computation and Simulation have always played a role in economics – whether it be pure economic theory or any variant of applied, especially policy-oriented, macro- and microeconomics or what has increasingly come to be called empirical or experimental economics. Computations and simulations are also intrinsically dynamic. This triptych – computation, simulation and dynamic – is given natural foundations, mainly as a result of developments in the mathematics underpinnings in the potentials of computing, using digital technology. A running theme in this (...) essay is the recognition that, increasingly, the development of economic theory seems to go hand in hand with advances in the theory and practice of computing, which is, in turn, a catalyst for the move away from too much reliance on any kind of mathematics for the formalisation of economic entities that is inconsistent with the mathematical, methodological and epistemological foundations of the theory of computation.

A relatively common approach in game studies understands gameworlds as constituting an existential situation for the player. Taking that stance, which is rooted in the European philosophical tradition of Existentialism, in this chapter we investigate the relationships and similarities between our existence within and without gameworlds. To do so, we first provide a review of existing literature in ‘existential ludology’ - work in game studies which considers our engagement with gameworlds from an existential perspective. In the second part of the (...) chapter, we then engage with some of the most notable ideas of the Norwegian philosopher Peter Wessel Zapffe. Zapffe understood human life as inherently meaningless and identified four ways in which human beings typically protect themselves from the existential panic that accompanies the awareness of that meaninglessness: isolation, anchoring, distraction, and sublimation. These four categories are used as the foundation for an examination of gameworlds as technologies for repressing existential panic. (shrink)

Transhumanism and Gnosis: A Parallelism The aim of this paper is to draw a parallel between the phenomenon of gnosis and transhumanism together with its ultimate version, posthumanism. After some methodological clarifications, the paper focuses on four confrontational axes: self-recognition, cosmic and anthropological dualism, the meaning of morality, death and suffering, and finally the promise of salvation. Finally, the two doctrines are framed within the context of the Gnostic revolution, emphasizing the sense of uprootedness and post-modernity to explain the resurgence (...) of these phenomena.

This book offers a broad and timely perspective on research on olfaction and its current technological challenges. It specifically emphasizes the interdisciplinary context in which olfaction is investigated in contemporary research. From aesthetics to sociology, from bioengineering to anthropology, the different chapters discuss a wide variety of issues arising from olfaction research and its application in different contexts. By highlighting the overlaps between different areas of research, the book fosters a better communication between disciplines and leads towards a better understanding (...) of the role of olfaction in human perception and cognition. This inspiring read is of interest to students, researchers and practitioners in psychology, philosophy, bioengineering, and cultural studies. (shrink)

This paper aims to discuss ridicule in Plato. Often neglected in modern accounts of emotions, ridicule is in fact considered a pathos by Plato and extensively deployed in his dialogues. I will analyse ridicule from a descriptive, a normative, and a “practical” perspective, paying attention to how Plato understands its basic functioning, how he thinks that it should be regulated, and how he uses it in his dialogues. More generally, this paper will be an opportunity to explore some issues related (...) to the “pathe of the dialogue”, by which I mean both the emotions that are staged through the characters of Platonic fiction and the emotions which Plato aimed to elicit in his audience.

The Expanse does not provide an easy answer to the vexing question on making a decision when competing, but considering conflicts of values on the show can help us reason about tough choices in real life. Sometimes, scientific progress conflicts with the prudential value of self‐preservation. This chapter explains three ways of understanding value conflicts: as situations in which every option is forbidden, situations in which every option is permissible, or situations in which some options are obligatory and some options (...) are forbidden. The idea that all these different kinds of value can be traded with a common currency is tempting. But contra Keats, beauty is not truth; and it certainly is not goodness, as Tolstoy says. Epistemic, moral, prudential, and aesthetic values are very different. (shrink)
