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.

I argue that some utterances of sentences containing occurrences of indexical expressions should not be evaluated with respect to the context of utterance. I suggest that we distinguish between context of utterance and context of interpret‐ation, and I employ this distinction in the analysis of recorded messages and other interesting linguistic phenomena. I then discuss the implications of my views on contexts with respect to the logic of indexicals. Against the traditional view, I argue that sentences such as ‘I am (...) here now’ or ‘something exists’ should not be treated as logical truths. (shrink)

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.

This book explores what it means to exist in virtual worlds. Chiefly drawing on the philosophical traditions of existentialism, it articulates the idea that — by means of our technical equipment and coordinated practices — human beings disclose contexts or worlds in which they can perceive, feel, act, and think. More specifically, this book discusses how virtual worlds allow human beings to take new perspectives on their values and beliefs, and explore previously unexperienced ways of being. Virtual Existentialism will be (...) useful for scholars working in the fields of philosophy, anthropology, media studies, and digital game studies. (shrink)

I present a novel explanation of the apparent truth of certain remarks about fiction, such as an utterance of ''Salieri commissioned the Requiem'' during a discussion of the movie Amadeus. I criticize the traditional view, which alleges that the uttered sentence abbreviates the longer sentence ''it is true in the movie Amadeus that Salieri commissioned the Requiem''. I propose a solution which appeals to some independently motivated results concerning the contexts relevant for the semantic evaluation of indexical expressions.

The main aim of this paper is that of providing a unified analysis for some interesting uses of quotation marks, including so-called scare quotes. The phenomena exemplified by the cases I discuss have remained relatively unexplored, notwithstanding a growing interest in the behavior of quotation marks. They are, however, of no lesser interest than other, more widely studied effectsachieved with the help of quotationmarks. In particular, as I argue in whatfollows, scare quotes and other similar instances bear interesting relations with (...) someimportant themes in the study of natural languages, such as questions regarding alleged devicesof conventional implicature, cases of so-called metalinguistic negation, and, moregenerally, problems pertaining to the distinction between semantic and pragmatic fieldsof inquiry.In Section 1, I begin with a description of some examples involvingthe uses of quotation marks I intend to discuss, and I hint at some desiderata fortheir analysis. In Section 2, I temporarily abandon quotation marks, and, inspired by therecent work of Stephen Neale and Kent Bach on alleged devices of conventional implicature,I present what I call the theory of message and attachment. In Sections 3 and 4,I return to my initial examples, I employ the theory of message and attachment in theiranalysis, and I discuss certain features regarding the behavior of negation in some related cases.

How is scientific data used to represent phenomena and as evidence for claims about phenomena? In this paper, I propose that a specific type of claims – evidential claims – is involved in data practices to define and restrict the representational and evidential content of a dataset. I present an account of data practices in the epidemiology of the exposome based on the notion of evidential claims, which helps unpack the approaches, assumptions and warrants that connect different stages of research. (...) I identify three different strategies to generate different types of evidential claims in this case. The macro strategy, which individuates the dataset that serves as the initial evidential space for research. The micro strategy, which is used to generate evidential claims about the microscopic and individual component of target phenomena. The association strategy, that uses evidence from the other strategies to identify a dataset as representation of the different levels and relations of exposure and disease. Differentiating between these strategies sheds light on the multi-faceted landscape of biomedical research on environment and health; and the roles of data and evidence in the process of inquiry.

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)

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)

This essay proposes a systematic semantic account of Davidson’s demonstrative theory of pure quotation (Davidson Theory and decision, 11: 27–40, 1979) within a classic Kaplan-style framework for indexical languages (Kaplan 1977). I argue that Davidson’s informal hints must be developed in terms of the idea of ‘character-external’ aspects of meaning, that is, in terms of truth-conditionally idle restrictions on the class of contexts in which quotation marks may appropriately be used. When thus developed, Davidson’s theory may correctly take into account (...) the intuitively special status of disquotational sentences, such as “Boston’ refers to Boston’, and “‘Boston” refers to ‘Boston”, and is thus immune from the important objections recently raised in Cappelen and Lepore 2007.

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)

The idea of autonomy, presented as Kant’s main achievement in the Groundwork and the second Critique, is hardly present in the ethics of the “Doctrine of Virtue”. Against Pauline Kleingeld’s recent interpretation, I argue that this does not amount to a disappearance of the Principle of Autonomy, but to an important development of the notion of autonomy. I first show that Kant still advocated the Principle of Autonomy in the 1790s along with the thought of lawgiving through one’s maxims. I (...) then argue that the role of autonomy in Kant’s later ethics has a different focus than in the previous works, which requires to connect autonomy with autocracy. Conversely, in the “Doctrine of Virtue”, autocracy, which Kant had employed before as an independent notion, is construed as a new layer of autonomy. What Kant there calls subjective autonomy is thereby considered as reason’s self-government in the maxims of each rational agent. -/- . (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.

This article explores whether and under which circumstances it is ethically viable to include artificial beings worthy of moral consideration in virtual environments. In particular, the article focuses on virtual environments such as those in digital games and training simulations – interactive and persistent digital artifacts designed to fulfill specific purposes, such as entertainment, education, training, or persuasion. The article introduces the criteria for moral consideration that serve as a framework for this analysis. Adopting this framework, the article tackles the (...) question of whether including artificial intelligences that are entitled to moral consideration in virtual environments constitutes an immoral action on the part of human creators. To address this problem, the article draws on three conceptual lenses from the philosophical branch of ethics: the problem of parenthood and procreation, the question concerning the moral status of animals, and the classical problem of evil. Using a thought experiment, the concluding section proposes a contractualist answer to the question posed in this article. The same section also emphasizes the potential need to reframe our understanding of the design of virtual environments and their future stakeholders. (shrink)

This essay proposes a semantic analysis of biscuit-conditionals, such as Austin's classic example "there are biscuits in the cupboard if you want some". The analysis is grounded on the ideas of contextual restrictions, and of non-character encoded aspects of meaning, and provides a rigorous framework for the widespread intuitions that the if-clause in a biscuit-conditional is truth-conditionally idle, but it 'qualifies' the speech-act in question. In the concluding section of this essay, the analysis is also applied to the importantly similar (...) phenomenon of speech-act adverbs. (shrink)

This essay defends an analysis of malapropisms consistent with the Simple Picture of communication, namely the view that speakers communicate that P by employing expressions associated with P by the regularities appropriate for the linguistic community to which they belong. My analysis, grounded on the distinction between traces, shapes, and forms, is consistent with an intuitive assessment of the contents conveyed by instances of malapropisms, and with a standard, ‘fully articulated’ approach to semantic interpretation.

Classical arguments about the legitimate use of force have profoundly shaped the norms and institutions of contemporary international society. But what specific lessons can we learn from the classical European philosophers and jurists when thinking about humanitarian intervention, preventive self-defense or international trusteeship today? The contributors to this volume take seriously the admonition of contextualist scholars not to uproot classical thinkers' arguments from their social, political and intellectual environment. Nevertheless, this collection demonstrates that contemporary students, scholars and policymakers can still (...) learn a great deal from the questions raised by classical European thinkers, the problems they highlighted, and even the problematic character of some of the solutions they offered. The aim of this volume is to open up current assumptions about military intervention, and to explore the possibility of reconceptualizing and reappraising contemporary approaches. (shrink)

I present a Russellian analysis of Donnellan’s classic examples involving empty definite descriptions, such as a use of ‘the man with the Martini’ in a scenario in which the intended target is a teetotaler with water in his glass. Unlike the traditional Kripke‐style responses to Donnellan, my analysis grants semantic significance to the intuition that, in appropriate circumstances, such a use picks out the teetotaler. I then argue that the apparatus developed in my discussion of Donnellan’s examples may be successfully (...) applied to the semantic treatment of improper definite descriptions, such as ‘the table’ in Strawson’s ‘the table is covered with books.’.

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.

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.

William Kneale famously noted that "it is obviously trifling to tell [a man] that Socrates was called Socrates" . Leaving aside some debatable details in Kneale's example, it would indeed seem trivial to tell someone that, say, Socrates bears "Socrates."The reason why this sort of communication strikes us as eminently uninformative has occasionally been treated as the symptom of a semantic phenomenon—more precisely, as evidence in favor of nominal descriptive approaches to the semantic behavior of proper names such as "Socrates." (...) According to these approaches, it is obviously trifling to tell someone that Socrates bears "Socrates" because the descriptive condition of bearing "Socrates" is part of the meaning of "Socrates" in some semantically significant sense of "meaning." The aim of this essay is to present a novel counter-argument against nominal descriptivism, and to defend a nondescriptivist explanation of cases such as . In particular, it is argued that nominal descriptivism is independently untenable, since it yields incorrect logical verdicts, and even disregarding its independent inadequacy, nominal descriptivism does not provide an analysis of the peculiar status of preferable to the treatment proposed in what follows.
