The dynamics of ancient civilisations according to credited historians can be explained by means of a simple linear time-invariant feedback model whose loop only consists of a first-order process and a pure time delay. It is shown that, despite its simplicity, this model can give rise to a variety of responses, either oscillatory or aperiodic, such as those envisaged by A. Toynbee. Since modern civilisations are characterised by fast parameter variations, their description calls instead for a time-variant model. Simulations with (...) the linear parameter-varying model obtained from the aforementioned LTI model by letting its parameter vary are carried out to show the influence of different scenarios on the system response. Even if this model is elementary, it is believed that it may serve as a stimulating “tool for thought” in the ever-popular debate on the growth and decline of civilisations. (shrink)

Based on structural differences between spoken and written language, the purpose of this paper was to investigate whether spoken and written communication imply a different representation in reporting an experienced dream. In fact, the clausal-dynamic quality of the former and nominal-synoptic quality of the latter, with the consequent differences in length, cohesion and density, could enhance/reduce the perceptual character and narrative structure of report features often considered in order to assess sleep mentation. In particular, we wondered whether, after eliminating all (...) the elements responsible for the more conspicuous quantitative differences across the two forms , we would obtain two equivalent ways of reporting dreams. Three hundred and two subjects, raging in age from 18 to 40 years, participated as volunteers in the study and were asked to complete a dream diary daily for 14 days, by tape-recording their own dreams and putting them down in writing. The reports were analyzed by a psycholinguistic system. Results indicated that the report modality is able to affect the dream experience representation, conditioning the figurative translation carried out by the tester: written forms show a loss of hallucinatory information and a non-complete correspondence also of the bizarreness features with respect to the spoken texts. Partialling out for length eliminated any difference between spoken and written dream reports on bizarreness; on the other hand, controlling the sequence effect of the report did not introduce changes. Methodological and theoretical implications were discussed. (shrink)

It is common to hear talk of the aim of belief and to find philosophers appealing to that aim for numerous explanatory purposes. What belief 's aim explains depends, of course, on what that aim is. Many hold that it is somehow related to truth, but there are various ways in which one might specify belief 's aim using the notion of truth. In this article, by considering whether they can account for belief 's standard of correctness and the epistemic (...) norms governing belief, I argue against certain prominent specifications of belief 's aim given in terms of truth, and advance a neglected alternative.

The _Physics_ is a foundational work of western philosophy, and the crucial one for understanding Aristotle's views on matter, form, essence, causation, movement, space, and time. This richly annotated, scrupulously accurate, and consistent translation makes it available to a contemporary English reader as no other does—in part because it fits together seamlessly with other closely associated works in the New Hackett Aristotle series, such as the _Metaphysics_, _De Anima_, and forthcoming _De Caelo_ and _On Coming to Be and Passing Away_. (...) Eventually the series will include all of Aristotle's works. Sequentially numbered endnotes provide the information most needed at each juncture, while a detailed Index of Terms indicates places where focused discussion of key notions occurs. An illuminating general Introduction describes the book that lies ahead, explaining what sort of work it is and what sorts of evidence it relies on. (shrink)

O presente texto discute, em âmbito teórico, a relação entre acontecimento e narrativa midiática. Através de Louis Quéré, situa-se o acontecimento na dialética da experiência, originária da interação entre sujeitos e acontecimentos. Pensa-se a narrativa como um lugar de manifestação e representação das culturas e das ações dos sujeitos sobre o mundo. Volta-se para a narrativa por meio da tríplice mimese de Paul Ricoeur. No âmbito analítico, o texto realiza incursões e interpretações acerca da derrota da seleção brasileira de futebol (...) para a seleção alemã por sete gols a um na semifinal da Copa do Mundo de Futebol de 2014 e busca compreender como as capas de alguns jornais brasileiros produzem uma ressignificação do revés do Brasil na Copa de 1950, conhecido como Maracanaço.

Dans cet article j’analyse le concept de transmutatio corporalis dans la théorie des passions de Thomas d’Aquin. Je prends en considération surtout le traité sur les passions contenu dans la Somme de théologie, mais aussi d’autres textes du maître dominicain : le Commentaire sur les Sentences, les Questions disputées sur la vérité, le bref traité Sur le mouvement du cœur. Tout d’abord, je montre comment l’idée de transmutatio corporalis est essentielle pour la définition thomasienne de la passion, puis j’identifie en (...) quoi consiste cette modification corporelle dans les principales passions. Je termine avec l’analyse de la transmutatio corporalis dans la dynamique entre l’âme et le corps, m’arrêtant notamment sur l’idée de la redundantia, à savoir le processus circulaire par lequel l’âme modifie le corps et le corps modifié intervient sur l’âme.

Sometimes, learning about the origins of a belief can make it irrational to continue to hold that belief—a phenomenon we call ‘genealogical defeat’. According to explanationist accounts, genealogical defeat occurs when one learns that there is no appropriate explanatory connection between one’s belief and the truth. Flatfooted versions of explanationism have been widely and rightly rejected on the grounds that they would disallow beliefs about the future and other inductively-formed beliefs. After motivating the need for some explanationist account, we raise (...) some problems for recent versions of explanationism. Learning from their failures, we then produce and defend a more resilient explanationism. (shrink)

Infallibilism is the view that a belief cannot be at once warranted and false. In this essay we assess three nonpartisan arguments for infallibilism, arguments that do not depend on a prior commitment to some substantive theory of warrant. Three premises, one from each argument, are most significant: if a belief can be at once warranted and false, then the Gettier Problem cannot be solved; if a belief can be at once warranted and false, then its warrant can be transferred (...) to an accidentally true belief; if a belief can be at once warranted and false, then it can be warranted and accidentally true. We argue that each of these is either false or no more plausible than its denial. Along the way, we offer a solution to the Gettier Problem that is compatible with fallibilism. (shrink)

Supererogatory acts—good deeds “beyond the call of duty”—are a part of moral common sense, but conceptually puzzling. I propose a unified solution to three of the most infamous puzzles: the classic Paradox of Supererogation (if it’s so good, why isn’t it just obligatory?), Horton’s All or Nothing Problem, and Kamm’s Intransitivity Paradox. I conclude that supererogation makes sense if, and only if, the grounds of rightness are multi-dimensional and comparative.

A pergunta sobre o bem viver, a justiça e a reta ação moral acompanham a trajetória histórica do ser humano. Diante de uma sociedade plural e relativista como a nossa, a ética do discurso de Habermas apresentase como um procedimento fecundo de justificação e de validação do agir humano.

Background The increasing incidence of people affected by overweight or obesity is a significant health problem. The knowledge of the factors which influences the inappropriate eating behaviours causing excessive body fat is an essential goal for the research. In fact, overweight and obesity are significant risk factors for many health diseases, such as cardiovascular problems, diabetes, etc. Recently, many studies have focused on the relationship between body weight and cognitive processes. Objectives This systematic review is aimed to investigate the existence (...) and the nature of the relationship between excessive body weight (overweight/obesity) and executive functions, analysing cross-sectional and longitudinal studies in order to verify the evidence of a possible causality between these variables. Methods The review was carried out according to the PRISMA-Statement, through systematic searches in the scientific databases PubMed, Medline, PsychInfo, and PsycArticles. The studies selected examined performance on executive tasks by participants with overweight or obesity, aged between 5 and 70 years. Studies examining eating disorders or obesity resulting from other medical problems were excluded. Furthermore, the results of studies using a cross-sectional design and those using a longitudinal one were separately investigated. Results Sixty-three cross-sectional studies and twenty-eight longitudinal studies that met our inclusion and exclusion criteria were analysed. The results confirmed the presence of a relation between executive functions and overweight/obesity, although the directionality of this relation was not clear; nor did any single executive function emerge as being more involved than others in this relation. Despite this, there was evidence of a reciprocal influence between executive functions and overweight/obesity. Conclusions This systematic review underlines the presence of a relationship between executive functions and overweight/obesity. Moreover, it seems to suggest a bidirectional trend in this relationship that could be the cause of the failure of interventions for weight reduction. The results of this review highlight the importance of a theoretical model able to consider all the main variables of interest, with the aim to structuring integrated approaches to solve the overweight/obesity problems.

In Lukács: Praxis and the Absolute, Daniel Andrés López reassembles Lukács’s philosophy of praxis on a Hegelian basis, as a conceptual-historical totality, both defending him and proposing an unprecedented, immanent critique that raises problems for Marxian philosophy as a whole.

" Qualia " is an unfamiliar term for something that could not be more familiar to each of us: the ways things seem to us. As is so often the case with philosophical jargon, it is easier to give examples than to give a definition of the term. Look at a glass of milk at sunset; the way it looks to you--the particular, personal, subjective visual quality of the glass of milk is the quale of your visual experience at the (...) moment. The way the milk tastes to you then is another, gustatory quale, and how it sounds to you as you swallow is an auditory quale; These various "properties of conscious experience" are prime examples of qualia. Nothing, it seems, could you know more intimately than your own qualia ; let the entire universe be some vast illusion, some mere figment of Descartes' evil demon, and yet what the figment is made of will be the qualia of your hallucinatory experiences. Descartes claimed to doubt everything that could be doubted, but he never doubted that his conscious experiences had qualia, the properties by which he knew or apprehended them. (shrink)

The social sciences playa variety of multifaceted roles in the policymaking process. So varied are these roles, indeed, that it is futile to talk in the singular about the use of social science in policymaking, as if there were one constant relationship between two fixed and stable entities. Instead, to address this issue sensibly one must talk in the plural about uses of dif ferent modes of social scientific inquiry for different kinds of policies under various circumstances. In some cases, (...) the influence of social scientific research is direct and tangible, and the connection between the find ings and the policy is easy to see. In other cases, perhaps most, its influence is indirect-one small piece in a larger mosaic of politics, bargaining, and compromise. Occasionally the findings of social scientific studies are explicitly drawn upon by policymakers in the formation, implementation, or evaluation of particular policies. More often, the categories and theoretical models of social science provide a general background orientation within which policymakers concep tualize problems and frame policy options. At times, the in fluence of social scientific work is cognitive and informational in nature; in other instances, policymakers use social science primarily for symbolic and political purposes in order to le gitimate preestablished goals and strategies. Nonetheless, amid this diversity and variety, troubling general questions persistently arise. (shrink)

The nature of mathematical objects outlined Abstract: The nature of mathematical objects is one of the themes in the process of teaching mathematics that reflects distinctive positions. Based on this premise, the present article aims to discuss the historical-logical process of development of Mathematics, taking into account the specifics of its objects, found on unrealistics and realistics concepts. Furthermore, it considers the manifestations in the comprehension of metaphysics inversion of these objects. This objective emerges from the following question: How is the comprehension of the nature of mathematical objects in the process of development of this science based on materialistic and idealistic, realistic and unrealistic concepts expressed? The discussion begins with the characterization of the mathematical objects from the realistics and unrealistics manifestations, with an emphasis on the process of entification which was carried out by pythagoreans, such as Plato and Aristotle. Subsequently, it provides the characterization of the comprehension of the mathematical objects based on idealism and materialism. The approaches applied are based on another one, that is the philosophical and historical one, which intends to unveil the essence by which it expresses the comprehension of the mathematical objects as paramount for the educational process. Key-words: Philosophy of Mathematics; Mathematical concepts; Mathematics Education.

This article aims to analyze some important categories of Lima Vaz’s ethics, such as: recognition, consensus, achievement, dignity and moral person, in order to prove the idea that there is no ethical act in the community ethics rather than recognizing that ethical subjects need to reciprocally recognize the dignity of every human being and consent to the pursuit of the good. Therefore, we seek to articulate the text in three moments. First, it seeks to argue that the human being, as (...) structural being and being relational, seeks to fulfill itself as such. Second, it is a matter of showing that ethical action is dialectically effective in the bosom and in the life of the community that takes as its end the horizon of the Good in which the ethical subject achieves its fulfillment. And, third, to present the category of moral person as the crowning achievement of Lima Vaz’s ethics, since realizing one’s own life fundamentally supposes an appeal to the human being to become on the plane of duty to be, that is, on the plane of ethics, that which is already on the ontological plane, namely, person. Keywords: Lima Vaz. Consensus. Realization. Dignity. Moral person. (shrink)

Supererogatory acts are those that lie “beyond the call of duty.” There are two standard ways to define this idea more precisely. Although the definitions are often seen as equivalent, I argue that they can diverge when options are infinite, or when there are cycles of better options; moreover, each definition is acceptable in only one case. I consider two ways out of this dilemma.

1. Happiness, then and now -- Happiness, eudaimonia, and practical reasoning -- Happiness as eudaimonia -- Happiness and virtuous activity -- New directions from old debates -- 2. Happiness then: the sufficiency debate -- Aristotle's case against the sufficiency thesis -- 3. Happiness now: rethinking the self -- Socrates' case for the sufficiency thesis -- Epictetus and the stoic self -- The Stoics' case for the sufficiency thesis -- The embodied conception of the self -- The embodied conception and psychological (...) well-being -- The Stoics' case against the embodied conception.

Public discussions of political and social issues are often characterized by deep and persistent polarization. In social psychology, it’s standard to treat belief polarization as the product of epistemic irrationality. In contrast, we argue that the persistent disagreement that grounds political and social polarization can be produced by epistemically rational agents, when those agents have limited cognitive resources. Using an agent-based model of group deliberation, we show that groups of deliberating agents using coherence-based strategies for managing their limited resources tend (...) to polarize into different subgroups. We argue that using that strategy is epistemically rational for limited agents. So even though group polarization looks like it must be the product of human irrationality, polarization can be the result of fully rational deliberation with natural human limitations. (shrink)

From an early age, humans know a surprising amount about basic physical principles, such as gravity, force, mass, and shape. We can see this in the way that young children play, and manipulate objects around them. The same behaviour has long been observed in primates - chimpanzees have been shown to possess a remarkable ability to make and use simple tools. But what does this tell us about their inner mental state - do they therefore share the same understanding to (...) that of a young child? Do they understand the simple, underlying physical principles involved? Though some people would say that they do, this book reports groundbreaking research that questions whether this really is the case. -/- Folk Physics for Apes challenges the assumptions so often made about apes. It offers us a rare glimpse into the workings of another mind, examining how apes perceive and understand the physical world - an understanding that appears to be both similar to, and yet profoundly different from our own. The book will have broad appeal to evolutionary psychologists, developmental psychologists, and those interested in the sub-disciplines of cognitive science (philosophy, anthropology). The book additionally offers for developmental psychologists some valuable new non-verbal techniques for assessing causal understanding in young children. (shrink)

Sometimes it takes years of debate for philosophers to discover what it is they really disagree about. Sometimes they talk past each other in long series of books and articles, never guessing at the root disagreement that divides them. But occasionally a day comes when something happens to coax the cat out of the bag. "Aha!" one philosopher exclaims to another, "so that's why you've been disagreeing with me, misunderstanding me, resisting my conclusions, puzzling me all these years!".

A remarkable number of Nietzsche's substantive moral psychological views have been borne out by evidence from the empirical sciences. Moral judgments are products of affects on Nietzsche's view, but the latter are in turn causally dependent upon more fundamental features of the individual. Nietzsche accepts a doctrine of types. The path is short from the acceptance of the Doctrine of Types to the acceptance of epiphenomenalism, as Leiter, and more recently, Riccardi argue. This chapter explains Nietzsche's phenomenological account of willing, (...) which serves as independent motivation for the view that Nietzsche denies the causal efficacy of conscious acts of willing. It also explores that in spite of an absence of volitional freedom, self‐control can be usefully understood on a strength‐model of motivational resources. The chapter concludes with a brief discussion of how Nietzsche, without employing the contemporary methods of empirical psychology, could nonetheless be such a prescient moral psychologist. (shrink)

Philosophers have found postulating possible worlds to be very useful in a number of areas, including philosophy of language and mind, logic, and metaphysics. Impossible worlds are a natural extension to this use of possible worlds, and can help resolve a number of difficulties thrown up by possible‐worlds frameworks.

It has become customary to conceptualize the living cell as an intricate piece of machinery, different to a man-made machine only in terms of its superior complexity. This familiar understanding grounds the conviction that a cell's organization can be explained reductionistically, as well as the idea that its molecular pathways can be construed as deterministic circuits. The machine conception of the cell owes a great deal of its success to the methods traditionally used in molecular biology. However, the recent introduction (...) of novel experimental techniques capable of tracking individual molecules within cells in real time is leading to the rapid accumulation of data that are inconsistent with an engineering view of the cell. This paper examines four major domains of current research in which the challenges to the machine conception of the cell are particularly pronounced: cellular architecture, protein complexes, intracellular transport, and cellular behaviour. It argues that a new theoretical understanding of the cell is emerging from the study of these phenomena which emphasizes the dynamic, self-organizing nature of its constitution, the fluidity and plasticity of its components, and the stochasticity and non-linearity of its underlying processes.

Realists about possible worlds typically identify possible worlds with abstract objects, such as propositions or properties. However, they face a significant objection due to Lewis (1986), to the effect that there is no way to explain how possible worlds-as-abstract objects represent possibilities. In this paper, I describe a response to this objection on behalf of realists. The response is to identify possible worlds with propositions, but to deny that propositions are abstract objects, or indeed objects at all. Instead, I argue (...) that realists should follow Prior (1971) and others in treating higher-order quantification (e.g. quantification into predicate or sentence position) as a genuine form of quantification in its own right, and so in particular, not to be analysed in terms of first-order quantification over abstract objects. I argue that from this ‘higher-orderist’ perspective, there is a relatively straightforward answer to the question of how possible worlds-as-propositions succeed in representing possibilities.

One way of being responsible for an action is being praiseworthy for it. But what is the “praise” of which the praiseworthy agent is worthy? This paper provides a survey of answers to this question, i.e. a survey of possible accounts of praise’s nature. It then presents an overview of candidate norms governing our responses of praise. By attending to praise’s nature and appropriateness conditions, we stand to acquire a richer conception of what it is to be, and to regard (...) another as, a responsible agent. (shrink)
