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 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)

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.

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)

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)

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.

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 Euclidean ‘Division of the canon’ and Pythagorean harmonics: The article presents the first Polish translation of a short Ancient Greek treatise entitled The division of the canon, which is commonly dated to the 3rd century BC, with a doubtful assumption that the author of the treatise is Euclid himself. It is the oldest surviving text derived from the mathematical school of harmonics, which combined the mathematical theory of proportion with the musical laws of harmony. The main purpose of this (...) Euclidean treatise is to describe the instrument called canon, which consists in determining the successive notes of the Greek musical system by means of mathematical principles. The treatise essentially consists of two distinct parts: an introduction and twenty propositions in the style of Euclid’s Elements. To bring this highly esoteric text closer to the modern reader, the translation is preceded by a brief introduction, which deals with the basic issues of the transmission of the text, its structure, and the problem of authorship. The philosophical problems of the treatise and its basic concepts are also discussed. An underlying idea of both the introduction and the work on the translation is that The division of the canon is an eminently Pythagorean text, which both expressed and proved their conviction about the mathematical structure of the universe.

Bien qu’il tende à interpréter l’ἐποχή comme une position personnelle d’Arcésilas, Thomas Bénatouïl admet cependant que cette interprétation n’est pas pleinement justifiée par nos sources, lesquelles, loin d’être unanimes, font également état d’une interprétation exclusivement dialectique de l’ἐποχή περὶ πάντων. Mais s’il en est ainsi, il est également difficile de soutenir qu’Arcésilas utilise un vocabulaire qui lui est propre pour exposer son point de vue ; en conséquence de quoi le mot ἄδη...

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)

La Collection Les Alchimistes Grecs della CUF si arricchisce d'un altro volume con un'opera del tutto nuova rispetto ai due volumi già pubblicati, l'Anonyme de Zuretti: il testo, che prende il nome da C. O. Zuretti, il quale ne curò nel 1930 l'editio princeps nel VII volume del Catalogue des manuscrits alchimistes grecs, è «un traité pratique, complet et systematique, rédigé à l'époque médiévale par un Grec d'Italie du Sud. Celui-ci se base sur de nombreuses sources latines et arabo-latines, sans (...) renier pour autant la tradition grecque, et il écrit dans une langue déroutante … respectée au maximum» (p. VII). Come scrive l'Editrice nell'Avant-propos, questa sintesi delle conoscenze alchemiche mediterranee degli inizi del 1300 è il più lungo dei testi alchemici greci e presenta diversi motivi di interesse: • è il testimone del sincretismo culturale che fioriva nel regno di Napoli in epoca angioina; • è un documento interessante per lo studio della lingua greca medievale della Calabria; • permette di affrontare problemi filologici legati al fenomeno della traduzione.

Previous studies have reported a significant positive association between ability emotional intelligence and attachment security. However, these studies may, to some extent, be misleading because they relied on self-report measures of attachment security. Furthermore, to our knowledge, no study has yet investigated the relationship between ability EI and mentalization, operazionalized as reflective functioning, although EI and RF were assumed to be “conceptual cousins.” In an attempt to overcome some of the limitations of the previous research, the current study investigated the (...) relationships between ability EI, attachment security, and mentalization measured via the Adult Attachment Interview. Ninety-three volunteer participants from an Italian community population, aged from 27 to 55 years, took part in the study. Significant positive correlations were found between ability EI, attachment security, and RF. The results shed some light on the relationship between different attachment strategies and ability EI. Hyperactivating attachment strategies correlated negatively with ability EI, while the correlation between ability EI and attachment deactivating strategies depend on which defensive strategy is used: avoiding the painful emotional contact with the memory of unpleasant childhood attachment experiences positively correlated with experiential EI, whilst the resort to derogation of the attachment needs correlated with impairment in EI. Findings from the current study suggest that future studies in developmental psychology are needed to investigate the development of the ability EI in relation to the quality of the attachment models more in-depth.

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.

The paper is about the connotations of the philosophical novel. It explores the question of whether and how the philosophical novel can become functional model for philosophical praxis. I argue that the philosophical novel is a tool for activating a relational process whereby the concept of “situated relationship” becomes clear and is enhanced in conjunction with the activation of philosophical praxis. A “situated relationship” is identified as a relational practice which is contextualized and exerted in and between thinking, language and (...) action, within the framework of an educational process which becomes a dialogue-oriented research through relational networks. This form of thinking is not only Logos, but also Pathos and Ethos, inasmuch as the interconnection of thinking, language, meaning and behavior is made manifest, recognized and practiced in thinking and with thinking. By fostering awareness of the cognitive and affective dimensions, this form of thinking can extend such awareness to the relational dimension, interpersonal and intrapersonal, within a constant circular form of complementarity.

ABSTRACT Even if Lotman’s theory has often been presented as a semiotic theory based on categories of space, temporal categories are crucial as well. And as we can speak of polyglotism as one of the main features of culture, we should speak of polychronism as well. In each state of culture, in fact, we find many temporal codes, and the internal dialogue is not only based on codes coming from different spaces (in the normal sense of polyglotism), but also as (...) coming from different times (in the sense of a sort of polychronism). Lotman’s reflections about this aspect of culture could be very useful in order to understand some aspects of our society, where we find a form of presentism, the temporal dimension corresponding to localism within the spatial dimension, which globalization has produced.

The subject of this contribution concerns the evolution of Eco’s thought on the problem of the false, from the first writings (in which the sign is just what can be used to lie) to the reflections of the late 1980s on the strength of the false, in a more culturological perspective. The essay will therefore trace an evolution that establishes in Eco’s theory a continuity between reflection on falsehood, reflection on falsification and the theory of fiction, while in a second (...) time it will retrace all of Eco’s narrative going to highlight how all novels have to do with the false, or at least with the non-verifiability of the true. From this point of view, it will be argued that novels are the best place for Eco to affirm the strength of the false, for the nomothetic power of fictions. (shrink)

The aim of my contribution is to analyse the role that common sense has played in Umberto Eco’s work. After making clear the distinction between good sense and common sense, and highlighting a number of differences with the Scottish philosophy of common sense, I will consider the uses and functions that common sense assumes in Eco’s philosophy: namely, a phenomenological function, a regulatory function and a communicative function. I will demonstrate how the characterisation of common sense in Eco emphasises the (...) importance of the historical dimension of Sens, the importance of the public and social dimension of semiosis, and how common sense plays a fundamental, pragmatic role in the disposition to act, whilst revealing the importance of the Peircian lesson and Eco’s consonance with Peirce’s positions.
