This article sketches an idealized strategy for the identification of neural correlates of consciousness. The proposed strategy is based on a state space approach originating from the analysis of dynamical systems. The article then focuses on one constituent of consciousness, phenomenal awareness. Several rudimentary requirements for the identification of neural correlates of phenomenal awareness are suggested. These requirements are related to empirical data on selective attention, on completely intrinsic selection and on globally unconscious states. As an example, neuroscientific findings on (...) synchronized γ activity are categorized according to these requirements. (shrink)

Philosophical discussions on causal inference in medicine are stuck in dyadic camps, each defending one kind of evidence or method rather than another as best support for causal hypotheses. Whereas Evidence Based Medicine advocates the use of Randomised Controlled Trials and systematic reviews of RCTs as gold standard, philosophers of science emphasise the importance of mechanisms and their distinctive informational contribution to causal inference and assessment. Some have suggested the adoption of a pluralistic approach to causal inference, and an inductive (...) rather than hypothetico-deductive inferential paradigm. However, these proposals deliver no clear guidelines about how such plurality of evidence sources should jointly justify hypotheses of causal associations. We here develop such guidelines by first giving a philosophical analysis of the underpinnings of Hill’s viewpoints on causality. We then put forward an evidence-amalgamation framework adopting a Bayesian net approach to model causal inference in pharmacology for the assessment of harms. Our framework accommodates a number of intuitions already expressed in the literature concerning the EBM vs. pluralist debate on causal inference, evidence hierarchies, causal holism, relevance, and reliability.

Narrative allegory is distinguished from mythology as reality from symbol; it is, in short, the proper intermedium between person and personification. Where it is too strongly individualized, it ceases to be allegory […]. In the community of scholars of intermedia research, the above quoted citation is commonly regarded as Coleridge’s coining of the term “intermedium” or “intermediality”. However, a short glance at the discursive strategy of his argument emphasizes that his notion of “intermedium” must be closely linked to the poetics (...) and aesthetics of 19th-century romanticism. For the romantic poet, the term of “intermedium” does not point to media relations or intermedia processes but to.. (shrink)

According to the objective Bayesian approach to inductive logic, premisses inductively entail a conclusion just when every probability function with maximal entropy, from all those that satisfy the premisses, satisfies the conclusion. When premisses and conclusion are constraints on probabilities of sentences of a first-order predicate language, however, it is by no means obvious how to determine these maximal entropy functions. This paper makes progress on the problem in the following ways. Firstly, we introduce the concept of a limit in (...) entropy and show that, if the set of probability functions satisfying the premisses contains a limit in entropy, then this limit point is unique and is the maximal entropy probability function. Next, we turn to the special case in which the premisses are categorical sentences of the logical language. We show that if the uniform probability function gives the premisses positive probability, then the maximal entropy function can be found by simply conditionalising this uniform prior on the premisses. We generalise our results to demonstrate agreement between the maximal entropy approach and Jeffrey conditionalisation in the case in which there is a single premiss that specifies the probability of a sentence of the language. We show that, after learning such a premiss, certain inferences are preserved, namely inferences to inductive tautologies. Finally, we consider potential pathologies of the approach: we explore the extent to which the maximal entropy approach is invariant under permutations of the constants of the language, and we discuss some cases in which there is no maximal entropy probability function.

Theories of binding have recently come into the focus of the consciousness debate. In this review, we discuss the potential relevance of temporal binding mechanisms for sensory awareness. Specifically, we suggest that neural synchrony with a precision in the millisecond range may be crucial for conscious processing, and may be involved in arousal, perceptual integration, attentional selection and working memory. Recent evidence from both animal and human studies demonstrates that specific changes in neuronal synchrony occur during all of these processes (...) and that they are distinguished by the emergence of fast oscillations with frequencies in the gamma-range.

We study questionnaire responses to situations in which sacrificing one life may save many other lives. We demonstrate gender differences in moral judgments: males are more supportive of the sacrifice than females. We investigate a source of the endorsement of the sacrifice: antisocial preferences. First, we measure individual proneness to spiteful behavior, using an experimental game with monetary stakes. We demonstrate that spitefulness can be sizable—a fifth of our participants behave spitefully—but it is not associated with gender. Second, we find (...) that gender is consistently associated with responses even when we account for individual differences in the propensity to spitefulness. (shrink)

In this essay, we aim to provide an overview of the periodic table’s origins and history, and of the elements which conspired to make it chemistry’s most recognisable icon. We pay attention to Mendeleev’s role in the development of a system for organising the elements and chemical knowledge while facilitating the teaching of chemistry. We look at how the reception of the table in different chemical communities was dependent on the local scientific, cultural and political context, but argue that its (...) eventual universal acceptance is due to its unique ability to accommodate possessed knowledge while enabling novel predictions. Furthermore, we argue that its capacity to unify apparently disconnected phenomena under a simple framework facilitates our understanding of periodicity, making the table an icon of aesthetic value, and an object of philosophical inquiry. Finally, we briefly explore the table’s iconicity throughout its representations in pop art and science fiction. (shrink)

Augmented Reality (AR) is commonly defined as a digital layer of information viewed on top of the physical world through a smartphone, tablet or eyewear. Increasingly, this understanding of AR is shifting to a dynamic framework of ‘smart things’, including wearable technology, sensors and artificial intelligence (AI), with the ability to intercede in key moments and to deliver contextual and meaningful experiences. The things that come into context are the logical next steps in an evolutionary development towards computers that are (...) better able to show empathy in relation to people: even more human-oriented, anticipative and ubiquitous. Thus, this outsourcing of meaning to empathic technologies points to one of the fundamental questions concerning the relation of human and technology – the nature of the trust that users place in technology.

The present work carries us back to a period which, although chronologically no more than a generation or so behind us, has become as foreign to the present generation in Germany as if it were already a full hundred years old. Yet it was the period of Germany's preparation for the Revolution of 1848; and all that has happened in our country since then has been merely a continuation of 1848, merely the execution of the last will and testament of (...) the revolution. Just as in France in the eighteenth century, so in Germany in the nineteenth, a philosophical revolution ushered in the political collapse. But with what a difference! The French were in open combat with all official science, with the church and often also the state; their writings were printed beyond the frontier, in Holland or England, while they themselves were often on the point of landing in the Bastille. But the Germans were professors, state-appointed instructors of youth; their writings were recognized textbooks, and the system rounding off the whole development---the Hegelian system---was even raised, in some degree, to the rank of a royal Prussian philosophy of state! Was it possible that a revolution could hide behind these professors, behind their pedantically obscure phrases, their ponderous, wearisome sentences? Were not the liberals, the very people who then passed as the representatives of the revolution, the bitterest opponents of this brain-befuddling philosophy? But what neither governments nor liberals saw was seen by at least one man as early as 1833, and indeed by a man called Heinrich Heine. (shrink)

Epistemic scoring rules are the en vogue tool for justifications of the probability norm and further norms of rational belief formation. They are different in kind and application from statistical scoring rules from which they arose. In the first part of the paper I argue that statistical scoring rules, properly understood, are in principle better suited to justify the probability norm than their epistemic brethren. Furthermore, I give a justification of the probability norm applying statistical scoring rules. In the second (...) part of the paper I give a variety of justifications of norms for rational belief formation employing statistical scoring rules. Furthermore, general properties of statistical scoring rules are investigated. Epistemic scoring rules feature as a useful technical tool for constructing statistical scoring rules. (shrink)

As digital media becomes more central to the lives of adolescents, it also becomes increasingly relevant for their sexual communication. Sexting as an important image-based digital medium provides opportunities for self-determined digital communication, but also carries specific risks for boundary violations. Accordingly, sexting is understood either as an everyday, or as risky and deviant behavior among adolescents. In the affectedness of boundary violations gender plays an important role. However, it is still unclear to what extent digital sexual communication restores stereotypical (...) gender roles and restrictive sexuality norms or, alternatively, enables new spaces of possibility. In this sense, current research points to a desideratum regarding adolescents’ orientations toward sexting as a practice between spaces of possibility and boundary violations. This paper discusses the possibilities, but also the risks, of intimate digital communication among adolescents. The main question is, how adolescents themselves perceive sexting practices and how they position themselves between both spaces for possibility and for the exchange of unwanted sexual content. For this purpose, orientations toward normalities and gender of students are reconstructed. To answer these questions, twelve single-sex, group discussions were carried out with students aged 16 and 17 at five different secondary schools in northern Germany. A total of 20 boys and 22 girls took part. The group discussions were structured by a narrative generating guideline. The analysis draws its methodology from the Documentary Method, regarding implicit and explicit forms of knowledge and discourse. It results in a typology of three types with different orientations. The study shows, that most of the students consider sexting to be a risky practice; only one type shows normality in the use of sexting. At the same time, some of the young people are interested in experimenting with image-based intimate digital communication. Further, gender differences in use and affectedness are also documented. In this way, orientations toward gender stereotypes “favor” both the attribution of responsibility to girls, and overlook the responsibility of students who perpetrated the boundary violation. The orientations of adolescents should be taken more into account in research as well as in educational programs for the prevention of sexual violence. (shrink)

This paper presents the contributions of Alcindo Flores Cabral, professor of Chemistry at the Faculdade de Agronomia Eliseu Maciel, nowadays part of the Universidade Federal de Pelotas, to chemistry teaching. It is a contribution almost unknown to the Brazilian chemical community, although recognized as valuable by several renowned chemists abroad, like W. Hückel, G. Charlot, F. Strong, E. Fessenden and others. Cabral’s innovative helical representation is presented in connection not only with contemporary representations, but also an incursion is made into (...) the first helical systems proposed, those of Hinrichs and of Baumhauer. Some comments are made not only on Cabral’s Classificação Natural dos Elementos, published in 1946, but also about other texts he wrote for an efficient chemistry teaching. (shrink)

The doxastic zoo contains many animals: belief, acceptance, belief in, belief that, certainty, conjecture, guess, conviction, denial, disbelief in, disbelief that, judgment, commitment, etc. It also contains belief’s “strange bedfellows”: credences, partial beliefs, tacit beliefs, subdoxastic states, creedal feelings, feelings of knowing, in-between believings, pathological beliefs, phobias, aliefs, delusions, biases, besires. How to order the zoo? I propose to distinguish doxastic attitudes from non-doxastic epistemic attitudes. The criterion is the existence of correctness conditions. Most bedfellows do not have such normative (...) conditions. So they should not be allowed in the Doxastic Club. (shrink)

Este artigo apresenta a contribuição de Alcindo Flores Cabral (1907-1982) - professor de química da Faculdade de Agronomia Eliseu Maciel, hoje incorporada à Universidade Federal de Pelotas - ao ensino de química, uma contribuição quase desconhecida pela própria comunidade química brasileira, embora reconhecida como relevante por diversos químicos estrangeiros importantes, como W. Hückel, G. Charlot, F. Strong, E. Fessenden e outros. A inovadora representação helicoidal de Cabral é apresentada não só em conexão com representações contemporâneas, mas também inclui-se uma incursão (...) pelos primeiros sistemas helicoidais propostos, os de Hinrichs e de Baumhauer. Apresentam-se alguns comentários não somente sobre a Classificação natural dos elementos, publicada em 1946, mas também sobre outros textos escritos para tornar mais eficaz o ensino de química.

O presente trabalho examina os aspectos históricos da extração do óleo de canela-sassafrás (Ocotea pretiosa Mez), rico em safrol, no Alto e Médio Vale do Itajaí, a partir de 1940, por iniciativa de Otto Grimm, no município de Rio do Sul. Apresenta-se o tema no contexto da memória química em Santa Catarina, e discutem-se os procedimentos utilizados, e principalmente os motivos que levaram tal indústria incipiente a não se converter em uma indústria de química fina. Para tanto, são apresentados alguns (...) dados pertinentes à química do safrol, indicando que tal indústria poderia ter evoluído, bem como os aspectos econômicos e sociais que, ao lado da proibição do corte da canela-sassafrás, levaram em 1990 à extinção definitiva dessa "química fina que poderia ter sido".

Dos diferentes fatores associados a uma mudança de paradigma e, portanto, a uma revolução química, o menos discutido é o que envolve os assim chamados experimentos exemplares, mudanças radicais na metodologia de trabalho e nos procedimentos empíricos da química, mudanças e modificações estas que, no caso de uma ciência natural empírica, podem ter como consequência dados experimentais antes inacessíveis, levando, por fim, a uma nova abordagem de conceitos, hipóteses e teorias e desencadeando uma "revolução" química, um novo paradigma. Muito mais (...) do que uma revolução química, dever-se-ia optar por uma gradativa evolução química. Escolhemos três dessas situações como "exemplares": a modificação no procedimento empírico da química pneumática, com o uso da cuba pneumática contendo mercúrio; a introdução de novos métodos de extração de compostos orgânicos naturais, com a substituição do método pirogênico pelo de extração com solventes; um novo entendimento de "análise química", com a substituição da comparação de amostras tidas como autênticas pela decomposição do analito.

The chemist Max von Pettenkofer studied with Justus von Liebig, and after leaving Giessen in 1844 did not immediately find an academic position. During the period 1844/1845 he wrote a cycle of 16 Chemical Sonnets, but published them only in 1886. The Sonnets have with few exceptions a historiographical character. We present a translation of the Sonette into Portuguese as well as commentaries about their content and their philosophical significance. We also comment rather briefly on Pettenkofer’s career as an empirical (...) chemist and later as a somewhat heterodox hygienist. (shrink)

The author takes the interdisciplinary seminar on Evolutionary Epistemology at the 7th International Wittgenstein Symposium as the occasion to discuss the question of the status, achievements and limits of Evolutionary Epistemology. She comes to the conclusion that neither its critique of thequid juris question in traditional epistemology nor its own philosophical pretensions can be justified. But it is a new science which is relevant and a challenge to traditional epistemology and philosophy of science in that it opens up a horizon (...) of new questions which they will have to take seriously. Sie sind den Kindern ähnlich, die, wenn sie in einen Spiegel geguckt, ihn sogleich umwenden, um zu sehen, was auf der anderen Seite ist. Johann Wolfgang von Goethe Es gab Ewigkeiten, in denen (der menschliche Intellekt) nicht war;... nur sein Besitzer und Erzeuger nimmt ihn so pathetisch, als ob die Angeln der Welt sich in ihm drehten. Könnten wir uns aber mit der Mücke verständigen, so würden wir vernehmen, daß auch sie mit diesem Pathos durch die Luft schwimmt und in sich das fliegende Zentrum dieser Welt fühlt. Es ist nichts so verwerflich und gering in der Natur, was nicht durch einen kleinen Anhauch jener Kraft des Erkennens sofort wie ein Schlauch aufgeschwellt würde; und wie jeder Lastträger seinen Bewunderer haben will, so meint gar der stolzeste Mensch, der Philosoph, von allen Seiten die Augen des Weltalls teleskopisch auf sein Handeln und Denken gerichtet zu sehen.

Creating education systems that promote democratic sustainability has been the concern of political thinkers as diverse as J. S. Mill, Dewey, Benjamin Barber and Derek Bok. The classic dichotomisation of democratic theory between deliberative democrats and Schumpeterian democrats suggests that education in the service of democracy can be constructive—that is, provide a student with the skills necessary to elect her leaders without changing her nature—or reconstructive—that is, fundamentally and radically reshape the student to produce a citizen whose goals are transformed (...) to be congruent with society. Michael Oakeshott, who has written extensively both on political regimes and on the purpose of liberal education, offers a third way to assess the connection between government and education. Despite his own dismissal of civic or political education as fundamentally vocational and thus beyond the boundaries of the liberal arts, this paper provides a potentially surprising Oakeshottian defence of political education within the liberal arts with reference to the importance he places on experience as a pedagogic tool. Thus, Oakeshott's educational philosophy has a certain resonance with the recent calls to locate the relevance of liberal arts within the burgeoning development of experiential civic engagement programmes in American universities.

According to the mysteriousness objection, moral rights are wholly mysterious, metaphysically suspect entities. Given their unexplained character and dubious metaphysical status, the objection goes, we should be ontologically parsimonious and deny that such entities exist. I defend Tom Regan's rights view from the mysteriousness objection. In particular, I argue that what makes moral rights seem metaphysically mysterious is the mistaken tendency to reify such rights. Once we understand what moral rights are and what they are not, we will see that (...) rights talk is neither mysterious nor nonsensical. I then consider a second aspect of Regan’s rights view that some critics have found “mystifying.” I circumvent this objection by identifying and defending an alternative rights-conferring property. I conclude by pointing out the moral significance of these findings vis-à-vis our current treatment of nonhuman animals. (shrink)
