What are conspiracy theories? And what, if anything, is epistemically wrong with them? I offer an account on which conspiracy theories are a unique way of holding a belief in a conspiracy. Specifically, I take conspiracy theories to be self-insulating beliefs in conspiracies. On this view, conspiracy theorists have their conspiratorial beliefs in a way that is immune to revision by counter-evidence. I argue that conspiracy theories are always irrational. Although conspiracy theories involve an expectation to encounter some seemingly disconfirming (...) evidence (allegedly planted by the conspirators), resistance to all counter- evidence cannot be justified on these grounds.

The official documents of the Parisian Faculty of Arts (starting from the Statute of March 1255) show a close identification between the philosophical sciences and the corresponding textbooks: to learn a particular science means essentially to read certain, prescribed books. The case of theology seems to be different, however. In spite of the fact that the Bible served as a paradigm for the ‘textualization’ of all kinds of knowledge, and even of the whole world, it did not fit perfectly the (...) epistemological criteria which Aristotle’s Posterior analytics established as necessary for every science. Already in the second half of the 13thcentury, both Thomas Aquinas and Henry of Ghent tried to construct theology as a science, in the Aristotelean sense, by appealing respectively to the theory of the subalternation of the sciences and to the doctrine of the lumen medium. The different reactions to these two models by Godfrey of Fontaines, Durandus of Saint-Pourçain and Peter Auriol seem to indicate a process in which theology can constitute itself as a true science only through a broadening of its textual basis, outside the scope of Sacred Scripture.

Born out of a major international dialogue held at the Fondazione Giorgio Cini in Venice, Italy, this collection of essays presents innovative and provocative arguments about the claims of universal knowledge schemes and the different aesthetic and material forms in which such claims have been made and executed. Contributors take a close look at everything from religious pilgrimages, museums, and maps of the world, to search engines and automated GPS. Current obsessions in information technology, communications theory, and digital culture often (...) concern the value and possibility of a grand accumulation of universally accessible forms of knowledge: total libraries, open data bases, ubiquitous computing, and 'smart' technologies. These obsessions have important social and philosophical origins, and they raise profound questions about the very nature of knowledge and its organization. This volume's contributors draw on the histories of maps and of encyclopedias, worldviews and visionary collections, to make sense of the crucial relation between the way the world is known and how it might be displayed and transformed.

In much of the current academic and public discussion, conspiracy theories are portrayed as a negative phenomenon, linked to misinformation, mistrust in experts and institutions, and political propaganda. Rather surprisingly, however, philosophers working on this topic have been reluctant to incorporate a negatively evaluative aspect when either analyzing or engineering the concept conspiracy theory. In this paper, we present empirical data on the nature of the concept conspiracy theory from five studies designed to test the existence, prevalence and exact form (...) of an evaluative dimension to the ordinary concept conspiracy theory. These results reveal that, while there is a descriptive concept of conspiracy theory, the predominant use of conspiracy theory is deeply evaluative, encoding information about epistemic deficiency and often also derogatory and disparaging information. On the basis of these results, we present a new strategy for engineering conspiracy theory to promote theoretical investigations and institutional discussions of this phenomenon. We argue for engineering conspiracy theory to encode an epistemic evaluation, and to introduce a descriptive expression—such as ‘conspiratorial explanation’—to refer to the purely descriptive concept conspiracy theory.

Ante el panorama político doctrinario del siglo XIX caracterizado por dos filosofías opuestas y predominantes, como eran el liberalismo y el socialismo, en el presente artículo se sistematiza, por medio de una reconstrucción histórica y filosófica, la evolución del movimiento político de la Democracia Cristiana en Europa, en particular en Francia y Alemania, a través de las obras y acciones políticas de sus pioneros. Esta corriente ideológica se presenta como una �vía intermedia o alternativa� para un proyecto político fundado sobre (...) una visión cristiana de la vida y del hombre, equidistante de las posiciones del liberalismo y del socialismo radicales.

Researching for the sources of the Ars geomantiae – the oldest divinatory handbook of Western geomancy, translated from Arabic into Latin by Hugo of Santalla in 12th-century northern Spain – led to a double outcome: on the one hand, it showed the nature of Hugo’s cultural competence, imbued with the texts and scientific knowledge of his time; on the other hand, it revealed a series of historico-philosophical and philological data relating to the appearance of his version. In particular, the analysis (...) of the three explicit sources of the Sayings attributed to Socrates, of the Centiloquium of pseudo-Ptolemy and of the Isagoge ad Techne Galieni of Iohannitius has allowed not only to give a direct insight into the fundamental contribution of Arabic culture in the 12th-century translation of scientific studies, but also to carry out a more certain clarification on the dating of the Ars geomantiae and its placement within the translating activity of the master of Santalla. Finally, the question of the hermeticity of the text, raised by the reference to Enoch, one of the three Hermes of Abu- Ma’šar’s legend, has specified to what extent the Ars geomantiae belongs to the Hermetic tradition.

According to Thagard and Stewart :1–33, 2011), creativity results from the combination of neural representations, and combination results from convolution, an operation on vectors defined in the holographic reduced representation framework. They use these ideas to understand creativity as it occurs in many domains, and in particular in science. We argue that, because of its algebraic properties, convolution alone is ill-suited to the role proposed by Thagard and Stewart. The semantic pointer concept allows us to see how we can apply (...) the full range of HRR operations while keeping the modal representations so central to Thagard and Stewart’s theory. By adding another combination operation and using semantic pointers as the combinatorial basis, this modified version overcomes the limitations of the original theory and perhaps helps us explain aspects of creativity not covered by the original theory. While a priori reasons cast doubts on the use of HRR operations with modal representations :5039–5054, 1987) such as semantic pointers, recent models point in the other direction, allowing us to be optimistic about the success of the revised version.

While many sociocultural, contextual, biological, behavioral, and psychological variables may contribute to the widespread under-representation of girls and women in the science, technology, engineering, and mathematics field, this study focused on STEM-gender stereotypes, school experiences, and adolescence as critical factors in driving students' interest and motivation in STEM. Based on this, the study investigated differences by gender and national context in adolescents' STEM-gender stereotypes, school empowerment, and school engagement in a preliminary step, and simultaneously examined how adolescents' STEM-gender stereotypes were (...) related to school empowerment and school engagement as well as to socioeconomic status. These latter relations were considered within the context of the potential moderating role of gender and national context. Participants included 213 Italian adolescents and 214 Nigerian adolescents, who completed measures of school empowerment and engagement, STEM-gender stereotypes, and SES. A multivariate analysis of covariance showed that Nigerian girls and boys reported significantly higher levels of school empowerment, school engagement, and STEM-gender stereotypes than their Italian peers. Moreover, regardless of the national context, boys scored significantly higher on school empowerment and STEM-gender stereotypes than girls. Furthermore, a multiple-group path analysis revealed how higher school empowerment was related to lower STEM-gender stereotypes in both Italian and Nigerian girls' groups, while higher school engagement was associated with lower STEM-gender stereotypes only in the Nigerian groups. Regardless of gender and nationality, higher SES was linked to lower STEM-gender stereotypes. These findings particularly suggest that school empowerment and school engagement can be relevant dimensions to be studied and to develop strategies to counteract STEM-gender stereotypes in adolescence. Nonetheless, gender and national context are key factors to be considered. Limitations, strengths, future research, and educational implications are discussed. (shrink)

Previous studies consistently showed age-related differences in temporal judgment and temporal memory. Importantly, emotional valence plays a crucial role in older adults’ information processing. In this study, we examined the effects of emotions at the intersection between time and memory, analysing age-related differences in a temporal source memory task. Twenty-five younger adults (age range 18–35), 25 old adults (age range 65–74), and 25 old–old adults (age range 75–84) saw a series of emotional pictures in three sessions separated by a one-day (...) rest period. In the fourth session, participants were asked to indicate in which session (1, 2, or 3) they saw each picture. Results showed that old–old adults tended to collocate negative pictures distant in time, while positive stimuli were remembered as more recent than real, compared to neutral pictures. To a lower extent, people over 65 showed the same pattern of results. In contrast, emotional valence did not affect younger adults’ temporal positioning of stimuli. Current findings fit well with the Socio-Emotional Selectivity Theory’s assumptions and extended the literature on the positivity effect to temporal source memory. (shrink)

In the U.S., ‘employee wellness’ programs are increasingly attached to employer-provided health insurance. These programs attempt to nudge employees, sometimes quite forcefully, into healthy behaviors such as smoking cessation and exercise routines. Despite being widely promoted as saving on healthcare costs, numerous studies undermine this rationale. After documenting the programs’ failure to deliver a positive return on investment, we analyze them as instead providing an opportunity for employers to exercise increasing control over their employees. Based on human capital theory and (...) neoliberal models of subjectivity that emphasize personal control and responsibility, these programs treat wellness as a lifestyle that employees must be cajoled into adopting, extending the workplace not just into the home but into the bodies of workers, and entrenching the view that one belongs to one’s workplace. At the same time, their selective endorsement of health programs (many scientifically unsupported) produce a social truth of wellness framed as fitness for work. We conclude by arguing that the public health initiatives occluded by the private sector’s promotion of wellness programs would be a much better investment of resources. (shrink)

On the basis of an analysis of the relevant parts of Tractatus logico-philosophicus, a definition of the property of saying something, and of the obviously correlated property of saying nothing, is given. By applying that definition, both tautologies and contradictions are sanctioned as saying nothing, as lacking sense, in full agreement with Wittgenstein's explicit statements. On the other hand, a recent systematic attempt by A. Negro to extract from the Tractatus a criterion for sense containment and a criterion for saying (...) more, that is, for comparing the amount of sense of propositions, leads to the conclusion that the sense of any proposition is contained in the sense of a contradiction and that contradictions say more than any other propositions. The problem faced in this paper is that of restoring consistency between Negro's criteria, which on the whole give a correct interpretation of the text of the Tractatus, and Wittgenstein's thesis that, not only tautologies, but also contradictions say nothing.
