Araras, 4 de abril de 2017 Querido amigo José Esteves: Você não tem idéia do quanto fiquei contente ao receber a solicitação feita por sua amiga Cecília de uma bibliografia sobre o Centro Dom Vital. Foi você quem sugeriu que ela me telefonasse e eu fiquei feliz por ser lembrada depois de tanto tempo e lembrada por um amigo que me traz tantas e tão gratas recordações. Soube por ela, pela sua amiga, que você está aposentado e que continua muito (...) ativo, trabalhando em seus múltiplos interesses c... (shrink)

Enjoying great popularity in decision theory, epistemology, and philosophy of science, Bayesianism as understood here is fundamentally concerned with epistemically ideal rationality. It assumes a tight connection between evidential probability and ideally rational credence, and usually interprets evidential probability in terms of such credence. Timothy Williamson challenges Bayesianism by arguing that evidential probabilities cannot be adequately interpreted as the credences of an ideal agent. From this and his assumption that evidential probabilities cannot be interpreted as the actual credences of human (...) agents either, he concludes that no interpretation of evidential probabilities in terms of credence is adequate. I argue to the contrary. My overarching aim is to show on behalf of Bayesians how one can still interpret evidential probabilities in terms of ideally rational credence and how one can maintain a tight connection between evidential probabilities and ideally rational credence even if the former cannot be interpreted in terms of the latter. By achieving this aim I illuminate the limits and prospects of Bayesianism. (shrink)

On an evidentialist position, it is epistemically rational for us to believe propositions that are (stably) supported by our total evidence. We are epistemically permitted to believe such propositions, and perhaps even ought to do so. Epistemic rationality is normative. One popular way to explain the normativity appeals to epistemic teleology. The primary aim of this paper is to argue that appeals to epistemic teleology do not support that we ought to believe what is rational to believe, only that we (...) are permitted to do so. In arguing for that, I defend an epistemic teleological position that is radical in nature. It involves no commitment to aiming at the truth. I conclude by dispelling some worries that have been raised about my position. (shrink)

In everyday life and in science we acquire evidence of evidence and based on this new evidence we often change our epistemic states. An assumption underlying such practice is that the following EEE Slogan is correct: 'evidence of evidence is evidence' (Feldman 2007, p. 208). We suggest that evidence of evidence is best understood as higher-order evidence about the epistemic state of agents. In order to model evidence of evidence we introduce a new powerful framework for modelling epistemic states, Dyadic (...) Bayesianism. Based on this framework, we then discuss characterizations of evidence of evidence and argue for one of them. Finally, we show that whether the EEE Slogan holds, depends on the specific kind of evidence of evidence. (shrink)

The Stoic theory of knowledge was founded by Zeno on a perceptual and crudely materialistic base, but subsequently developed into an elaborate theory involving λεκτ which has proved difficult to reconstruct. The evolution of the school, influenced not only by internal differences but also by interaction with the Platonic Academy, certainly contributed to this development. Hence any adequate reconstruction of the Stoic theory of knowledge must take account of the differences among the positions of the different representatives of the school (...) with respect to the criticism put foward by the Academics. I propose here to clarify Zeno's position, showing how Arcesilaus' criticism helped to expose certain lacunae and thus to bring about changes in doctrine on the part both of Zeno himself and of his immediate successors.

A characterization of epistemic rationality, or epistemic justification, is typically taken to require a process of conceptual clarification, and is seen as comprising the core of a theory of (epistemic) rationality. I propose to explicate the concept of rationality. -/- It is essential, I argue, that the normativity of rationality, and the purpose, or goal, for which the particular theory of rationality is being proposed, is taken into account when explicating the concept of rationality. My position thus amounts to an (...) instrumentalist position about theories of epistemic rationality. Since there are different purposes, or goals, for which theories of rationality are proposed, the method of explication leaves room for different characterizations of rationality. I focus on two such (kinds of) purposes: first, the purpose of guiding the formation (or maintenance) of doxastic states and, second, the purpose of assessing (the formation or maintenance of) doxastic states. I conclude by outlining a pluralistic picture concerning rationality. (shrink)

In the literature, one finds two accounts of the normative status of rational belief: the ought account and the permissibility account. Both accounts have their advantages and shortcomings, making it difficult to favour one over the other. Imagine that there were two principles of rational belief or rational degrees of belief commonly considered plausible, but which, however, yielded a paradox together with one account, but not with the other. One of the accounts therefore requires us to give up one of (...) the plausible principles; whereas the other allows us to save them both. The fact that it allows us to save both of the plausible principles might well be considered a strong reason in favour of the relevant account. The permissibility-account-based resolution of the lottery paradox suggests that the permissibility account is a candidate for being supported in this way, since the account seems to save two plausible principles of rational belief and rational degrees of belief. I argue that even if the permissibility account were supported in this way the support would be defeated, since one cannot provide an analogous resolution of the preface paradox. The principles remain unsaved by the permissibility account. (shrink)

Adults who stutter (AWS) have demonstrated atypical coordination of motor and sensory regions during speech production. Yet little is known of the speech-motor network in AWS in the brief time window preceding audible speech onset. The purpose of the current study was to characterize neural oscillations in the speech-motor network during preparation for and execution of overt speech production in AWS using magnetoencephalography (MEG). Twelve AWS and twelve age-matched controls were presented with 220 words, each word embedded in a carrier (...) phrase. Controls were presented with the same word list as their matched AWS participant. Neural oscillatory activity was localized using minimum-variance beamforming during two time periods of interest: speech preparation (prior to speech onset) and speech execution (following speech onset). Compared to controls, AWS showed stronger beta (15-25Hz) suppression in the speech preparation stage, followed by stronger beta synchronization in the bilateral mouth motor cortex. AWS also recruited the right mouth motor cortex significantly earlier in the speech preparation stage compared to controls. Exaggerated motor preparation is discussed in the context of reduced coordination in the speech-motor network of AWS. It is further proposed that exaggerated beta synchronization may reflect a more strongly inhibited motor system that requires a stronger beta suppression to disengage prior to speech initiation. These novel findings highlight critical differences in the speech-motor network of AWS that occur prior to speech onset and emphasize the need to investigate further the speech-motor assembly in the stuttering population.

Definition of the problemIn medicine and bioethics, the term “suffering” is not clearly defined from a normative point of view. Nevertheless, suffering due to infertility is the starting point for medical interventions in assisted reproductive medicine. This implies that the unfulfilled desire to have children is a form of suffering, but the validity of this statement has not yet been clarified.ArgumentsBased on descriptions of some common concepts, certain characteristics of suffering are identified. We discuss the significance of suffering as an (...) anthropological condition in connection with the mission of medicine to alleviate human suffering. Furthermore, the risks of reproductive treatment and their significance for health are addressed.ConclusionWe conclude that the unfulfilled desire to have children is a form of suffering, and therefore has a normative value. The legitimacy of appropriate somatic intervention can only be established by taking the psycho-existential dimension of suffering into account. (shrink)

Der Begriff Leiden ist in der Medizin und in der Bioethik bisher kaum reflektiert und dahingehend in normativer Hinsicht wenig bestimmt. Dennoch bildet das Leiden an einer Unfruchtbarkeit den Ausgangspunkt für die medizintechnischen Interventionen der assistierten reproduktionsmedizinischen Behandlung. Dabei wird implizit angenommen, dass der unerfüllte Kinderwunsch ein Leiden ist. Ob der unerfüllte Kinderwunsch allerdings ein Leiden darstellt, ist bisher nicht eindeutig geklärt worden.Ziel dieses Beitrages ist es, die Annahme, dass es sich beim unerfüllten Kinderwunsch um ein Leiden handelt, zu überprüfen. (...) Anhand der Darstellung einiger gängiger Leidenskonzeptionen werden Merkmale von Leiden herausgearbeitet, die als treffende Grundannahmen für eine Leidensbestimmung gelten können. Es wird sich zeigen, dass der unerfüllte Kinderwunsch, entsprechend der Leidenskonzeptionen, als ein Leiden angesehen werden sollte, und ihm somit ein normativer Stellenwert zukommt. In einem weiteren Schritt ist zu klären, ob das Leiden an einem unerfüllten Kinderwunsch als ein Rechtfertigungsgrund für reproduktionsmedizinische Interventionen gelten kann. Dafür wird zum einen der Stellenwert von Leiden, als eine anthropologische Grundbedingung, im Zusammenhang mit dem Leidenslinderungsauftrag der Medizin diskutiert. Zum anderen werden die Risiken der reproduktionsmedizinischen Therapien sowie deren Bedeutung als Gesundheitsressourcen erörtert. Dabei wird deutlich, dass Leiden an einem unerfüllten Kinderwunsch immer ein psychosomatischer Komplex ist. Nur unter Berücksichtigung der psychoexistenziellen Dimension des Leidens ergibt sich eine Legitimation für eine angemessene somatische Intervention. (shrink)

This book explores the question of whether the ideal right to science and culture exists. It proposes that the human right to science and culture is of a utopian character and argues for the necessity of the existence of such a right by developing a philosophical project situated in postmodernity, based on the assumption of ‘thinking in terms of excendence’. The book offers a new way of thinking about access to knowledge in the postanalogue, postmodern society, and is inspired by (...) twentieth-century critical theorists such as Levinas, Gadamer, Bauman and Habermas.

This paper is the introduction to the Special Issue “Philosophical Methods”. The Special Issue will be published by Synthese.

In March 1986, a public symposium took place in Heidelberg about the “unresolved potential dangers of genetic engineering”. The event was organized by institutions affiliated with the environmental movement. Choosing this symposium as an example, the article shows how the public appearance of scientists can be understood as a form of political activism. The article shows how specialists from fields as diverse as biology, chemistry, physics, law and political sciences tried to place political messages by putting themselves in the limelight (...) as independent scientists. I argue that the symposium was both: a place of science communication intertwined with political agitation that, as should be noted, happened in a time when the West German government was working on the legislation of genetic engineering, legitimated by relying on independent expertise. It can be concluded that the discourse of scientific independence became a strategic tool in the controversial debate about the uses and dangers of genetic engineering. Thus, it draws attention to a dimension of political-scientific activity which cannot be fully grasped by the concept of ‘the expert’ that is established in the history of science. (shrink)

This study investigated the impact of maternal reflective functioning (RF) and attachment security on children’s mentalization. The Adult Attachment Interview (AAI) was administered to mothers in a sample of 41 mother–preadolescent dyads. AAI transcripts were rated in terms of the Berkeley AAI System ( Main and Goldwyn, 1998 ) and the Reflective Functioning Scale (RFS; Fonagy et al., 1998 ). Preadolescent mentalization was assessed using a semi-structured interview adapted from O’Connor and Hirsch (1999) and also by analyzing mental-state talk produced (...) during an autobiographical interview. Relationships between maternal RF and children’s mentalization were analyzed, with consideration given to the different RFS markers and references to positive, negative, and mixed-ambivalent mental states. Children’s mentalization was positively correlated with the mother’s RF, particularly the mother’s ability to mentalize negative or mixed-ambivalent mental states. No significant differences in mentalization were observed between children of secure and insecure mothers. (shrink)

The aim of the study was to examine the role of self-esteem in resisting the influence of materialistic goals of four social role models in adolescents. Previous studies showed a negative correlation between the psychological health of teens and striving for materialistic goals, one of the main sources is the social modeling of materialism. Two studies were carried out. The first, correlational study, was conducted on target teens and their mothers, fathers, and peers of their choice. It examined if self-esteem (...) is a moderator of the relationship between the materialism of social role models and the materialism of teens. The second, experimental study, was conducted on target teens only. It examined how boosting the self-esteem of teens and activating materialism of social role models may affect the materialism of teens. Study 1 showed a significant interaction effect of self-esteem and the materialism of peers on the materialism of teens. The interaction effects of self-esteem and other role models were not significant. Study 2 showed that elevated self-esteem lowered the influence of the materialism of peers on the materialism of teens. The results were not significant when other role models were analyzed. The results obtained in the presented studies indicate that the self-esteem of teens may have an important role in resisting the influence of materialism role models of peers. Practical implications of the studies for the psychological health of teens are also discussed. (shrink)

In many applications we have a set of objects together with their properties. Since the available information is usually incomplete and/or imprecise, the true knowledge about subsets of objects can be determined approximately only. In this paper, we discuss a fuzzy generalisation of two pairs of relation-based operators suitable for fuzzy set approximations, which have been recently investigated by Düntsch and Gediga. Double residuated lattices, introduced by Orlowska and Radzikowska, are taken as basic algebraic structures. Main properties of these operators (...) are presented. (shrink)

Aristoxenus's "Elements of Rhythm" stands as the earliest extant scientific treatise on rhythm, with only the second book enduring to our present day, albeit in an incomplete state. Demonstrating his allegiance to Aristotle, Aristoxenus employs Aristotelian concepts and investigative methods throughout his work. Notably, he introduces a conceptual division between the substance of rhythm (rhythmizomenon) and its rhythmic structure (rhythmos). Drawing parallels to Aristotle's temporal theory, Aristoxenus goes further by proposing a novel concept—the "protos chronos," denoting the smallest unit of (...) time. This nuanced exploration not only enriches our understanding of rhythm but also exemplifies Aristoxenus' adept application of Aristotelian principles in advancing the discourse on musical theory.

I focus on the No-Paradise Dilemma, which results from some initially plausible epistemic ideals, coupled with an assumption concerning our evidence. Our evidence indicates that we are not in an epistemic paradise, in which we do not experience cognitive failures. I opt for a resolution of the dilemma that is based on an evidentialist position that can be motivated independently of the dilemma. According to this position, it is rational for an agent to believe a proposition on the agent’s total (...) evidence just in case the (total) evidence stably supports the proposition. Based on this evidentialist position, I argue that it is not an epistemic ideal in the actual world that we hold rational beliefs that are logically equivalent to our rational beliefs. The dilemma is resolved by giving up this ideal for the actual world and adopting the evidentialist position in terms of stable evidential support. (shrink)

Material artefacts consist of many smaller – and ultimately natural – objects such as molecules and atoms that have been intentionally rearranged in such a way as to take the shape of a particular artefact and fulfil its functions. Whenever the arrangement of several parts results in properties that go beyond the properties of the individual parts or their sum, it can be said that this arrangement has resulted in a new object. Once created, material artefacts may take part in (...) natural processes such as reproduction and evolution and cannot be fundamentally distinguished from fully natural objects. This article provides a number of – mainly biological – examples that show the traditional Aristotelian dichotomy between nature and artefacts to be highly problematic and suggest a continuum instead. Most importantly, it is argued that living beings and artefacts are equally capable – or sometimes incapable – of self-reproduction and that there are numerous objects which are both living beings and artefacts.

When members of a group doxastically disagree with each other, decisions in the group are often hard to make. The members are supposed to find an epistemic compromise. How do members of a group reach a rational epistemic compromise on a proposition when they have different (rational) credences in the proposition? I answer the question by suggesting the Fine-Grained Method of Aggregation, which is introduced in Brössel and Eder 2014 and is further developed here. I show how this method faces (...) challenges of the standard method of aggregation, Weighted Straight Averaging, in a successful way. One of the challenges concerns the fact that Weighted Straight Averaging does not respect the evidential states of agents. Another challenge arises because Weighted Straight Averaging does not account for synergetic effects. (shrink)
