Como convém a uma autêntica interdisciplinaridade, é difícil separar comcontornos nítidos os dois aspectos da relação de Goethe com a História daCiência que me propus a discutir: como a História da Ciência vê a ciênciade Goethe?

Apesar da coerência interna, que permiteque “façamos nossos lances” como um enxadrista do livre-arbítrio, talestudo nos reserva muitas reflexões e surpresas.As (...) expected for an authentic interdisciplinary view of the subject, it isdifficult to establish a rigorously outlined separation of the twofold relationbetween Goethe and the History of Science: how History of Science viewsGoethe’s science?

ZusammenfassungEs ist in der Literatur weithin bekannt, dass im Gesundheitswesen auf unterschiedlichen Ebenen Allokationsentscheidungen getroffen werden. Während es auf der Makroebene um gesellschaftlich-politische Strukturfragen geht, stehen die Akteure der Mikroebene vor der Aufgabe, begrenzte Ressourcen in einer Organisation sinnvoll einzusetzen. In den ethischen Analysen der Mikro-Allokationsebene werden zumeist Entscheidungen der Healthcare Professionals thematisiert, weil sie eine unmittelbare Auswirkung auf die konkreten Patienten haben. Weniger in den Blick geraten Allokationen des Managements, welche die Rahmenbedingungen für Ressourcenzuteilungen beim Patienten betreffen. Hierbei geht (...) es nicht bloß um den Einsatz von Sachmitteln, sondern auch um den Personaleinsatz. Das Personalmanagement ist damit in wichtige Allokationsentscheidungen eingebunden und trägt eine dreifache Verantwortung: für die Gesundheit der Patienten, der Mitarbeiter und der Organisation. Der vorliegende Beitrag geht der Frage nach, welche Aspekte der Allokationsethik aus der Sicht des Personalmanagements in einem Krankenhaus zu bedenken sind, um der dreifachen Verantwortung gerecht zu werden. Dadurch zeigt sich, dass Allokationsethik in einem Krankenhaus nicht adäquat erfasst werden kann, ohne sich mit dem Personalmanagement zu beschäftigen, da das Personal die wertvollste Ressource ist, die es in einem Krankenhaus zu allozieren gilt.

Spengler’s Untergang des Abendlandes (The Decline of the West) (1918–22) was a sensational success in its own time, but has since slipped into oblivion. In this article I attempt to restore those aspects of his doctrine which could speak to us today and alert us to a crisis of the European Geist and its survival exigencies. This involves a reorientation on several issues on which our present perspectives differ from those that were current 100 years ago, such as the precedence (...) of his philosophical approach over the historical approach; the diminished importance of his extensive analysis and depiction of defunct civilisations, which serve at best as illustrative material rather than as direct comparisons on a somewhat risky notion of “simultaneity.” I also propose more relevant criteria in justification of his Faustianism (its sources and inception), and, not least, point to a differentiation between prediction and prognosis. The intention is to highlight the rationale behind Spengler’s enquiries into history—namely to situate Western civilisation in the overall scheme of human civilisations by alerting us to a decisive crossroads. This required of its author a means of identifying the symptoms that we must be aware of in order to sustain our world without tumbling unawares into a major catastrophe. The Untergang does not compulsorily wipe our civilisation out unless we provoke this to occur; instead, our civilisation may merge or blend peacefully with whatever culture(s) may be waiting to inaugurate a new cycle.

Counterfactual thought experiments in history have become increasingly popular in the last two decades, and a new and controversial branch of history has originated from their use: counterfactual history, also known as virtual history. Despite its popularity amongst the general public, most academic historians consider historical counterfactuals as having little epistemic value. This paper investigates three alleged uses of counterfactual thinking in historical explanations: the claim that counterfactual thinking gives historians useful insights; that it is a useful tool to evaluate (...) an event’s causal significance; that it shows much of history to be essentially ‘chaotic’. I argue that only convincingly justifies the use of counterfactual thought experiments in history, as it allows historians to illustrate how they perceive events’ degrees of sensitivity to changes to their causal history, being an important part of providing a causal explanation.

Isaiah Berlin famously attacked a view he called historical inevitability. He believed that a causal view of history entails the adoption of an extreme deterministic position – a kind of determinism which would rule out the possibility of free will, turning moral responsibility a notion void of meaning. His thesis was also based on the assumption that historians are not just chroniclers of the past but need to engage in moral judgments; therefore should determinism hold true of our world, our (...) moral language – and consequently much of our historical language – would need to undergo serious revision. In this brief article we look in some detail at the arguments offered by Berlin in support of his thesis and offer criticism. (shrink)

_ Source: _Volume 10, Issue 3, pp 349 - 369 A theory of causation suitable for historiography must accommodate the many types of causal claims historians make. In this paper, I examine the advantages of applying D. K. Lewis’s counterfactual theory of causation to the philosophy of historiography. I contend that Lewis’s possible world semantics offers a superior framework for making sense of historical causation, and that it lays the foundation for historians to look at history as causal series of (...) events, remaining agnostic as to whether there may be historical regularities or laws. Lewis’s theory can also accommodate important notions often used by historians, such as absences as causes, historical necessity and contingency, and the role they play in the formulation of historical counterfactuals.

Determinism is a doctrine or assumption best defined in the realm of the natural sciences. In this paper I explain in detail the four senses of determinism, from the most fundamental metaphysical sense, to the most complex epistemic (predictive) sense. I take as a starting point the analysis of determinism offered by Stephen Kellert. Each of these senses is then expounded and commented with a view to explore some of the implications of each of them in theoretical physics. The most (...) important of my tasks in this paper is to differentiate between the metaphysical and epistemic consequences of the deterministic assumption. My objective is to show that determinism as an ontological tenet is capable of withstanding criticism, even though predictive determinism is likely to be false. (shrink)

Este artigo investiga a “Tese” do primado do objeto na obra de Theodor W. Adorno, central ao seu materialismo não dogmático e relativamente pouco estudada. O primado do objeto será apresentado em seus elementos constitutivos, como crítica ao modo essencialmente idealista da dialética que perpassa o conjunto da obra de Adorno, em especial nos textos e discussões que precederam a publicação da Dialektik der Aufklãrung, para se explicitar no período de elaboração da Negative Dialektik. A “Tese” desenvolve momentos apresentados por (...) Lukács, Benjamin e Horkheimer, particularmente quanto ao nexo entre razão e experiência e se fundamenta especialmente no trajeto Kant – Hegel, como crítica ao idealismo, incorporando de modo estruturante as perspectivas de Marx e de Nietzsche. Ao romper a pretensa “simetria” entre sujeito e objeto, a “Tese” do primado do objeto revela como é insustentável a alegação habermasiana do Discurso filosófico da modernidade segundo a qual Adorno e Horkheimer incidiriam num ceticismo total frente à razão e à sua totalização ideológica. Ao contrário: estes autores, ao articularem de um modo original substância material histórica e argumentação teórica, contribuíram de modo fundamental para examinar o problema da reificação mediante sua relação à objetividade – como o não-idêntico – no âmbito da razão.

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 materialist approach of One-Dimensional Man emerges in a later work in which Marcuse connects the notion of “new sensibility” to a “complex intermediary function of the intellect.” Revolutionary praxis “is not simply negation but contradiction,” and thus Marcuse’s “new idea of reason” constructs a liberating rationality upon a technological one. This is accomplished by moving from an abstract “concept” of possibility to the perception of possibility as a “social alternative.” Here I examine the “dialectical logic” of human rights, which (...) critiques an unfree world and asserts itself as a political determinant dependent on the rupturing of established power.

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)

This paper highlights the role of Lewis’ Principal Principle and certain auxiliary conditions on admissibility as serving to explicate normal informal standards of what is reasonable. These considerations motivate the presuppositions of the argument that the Principal Principle implies the Principle of Indifference, put forward by Hawthorne et al..

ZusammenfassungIn den letzten Jahren wird intensiv darüber diskutiert, ob und in welcher Weise das Gewissen im Kontext der Apotheke zu schützen ist. Der Status quo in Deutschland und Österreich sieht keine gesetzliche Regelung für dieses Problem vor. Der ethische Rahmen für eine Bewältigungsstrategie im Umgang mit dem Problem der Gewissensfreiheit in der Apotheke wird deutlich gemacht. Unter Anwendung des rechtsethischen Verhältnismäßigkeitsprinzips wird das Problem mit Berücksichtigung des deutschen und österreichischen Verfassungsrechts sowie der Europäischen Menschenrechtskonvention auf individueller, korporativer und gesellschaftlicher Ebene (...) analysiert. Auf individueller Ebene sind die berechtigten Interessen und Güter des Apothekers einerseits und der Patientin andererseits durch eine grundrechtliche Verhältnismäßigkeitsprüfung zu einem schonenden Ausgleich zu bringen. Auf korporativer Ebene legitimiert das auf der Religions- und Weltanschauungsfreiheit basierende Selbstbestimmungsrecht die ideologisch profilierte Apotheke als Organisation und kann in der Binnenbeziehung der Apotheke einen Loyalitätskonflikt verursachen. Auf gesellschaftlicher Ebene stehen vier Optionen der proaktiven rechtspolitischen Gestaltung der Gewissensproblematik zur Verfügung: sozialstaatlich, libertär, professionsbezogen und kommunitär. Wie Konflikte auf individueller oder korporativer Ebene gelöst werden können, hängt von den Optionen ab, die auf gesellschaftlicher Ebene gewählt werden. Für den Fall einer Änderung des Status quo wird für zwei Lösungsansätze argumentiert: a) die Einführung einer qualifizierten Gewissensklausel für Apotheker (mit Beratungs-, Verweis-, Notfall- und Verständigungspflicht); b) die auf einen Kompromiss zwischen ideologisch profilierter pharmazeutischer Korporation (Apotheke oder Apothekervereinigung) und Sozialstaat abzielende „weiche“ kommunitäre Option.

Healthcare ethics consultation has been developed, practiced, and analyzed internationally. However, only a few professional standards have evolved globally in this field that would be comparable to standards in other areas of healthcare. This article cannot compensate for this situation. It contributes to the ongoing debate on professionalization by presenting experiences with ethics consultation in Austria, though. After exploring its contexts and providing an overview of one of its primary ethics programs, the article analyzes the underlying assumptions of “ethics consultation” (...) as an essential effort on the path to professionalize ethics consultation.

In this article, I present and explain ten different possible meanings of a chance event – some ontological, some epistemic – and provide examples whenever possible. I describe and illustrate more carefully the view of chance (tychē) expressed by Aristotle in his Physics, a demanding and complex notion, and contrast it to the other senses examined. The etymology of chance also reveals a cross-reference between chance and indeterminism. I draw attention to the fact that most of the definitions of chance (...) on offer need not conflict with causal determinism. (shrink)

Entlang der Verschiebungen des Kollektivbegriffs seit 1989 und seiner Verwendung in den performativen Künsten – und in Gegenüberstellung zu einer eher netzwerkartig organisierten Gesellschaft der Individuen – beschreibt der Beitrag, wie durch den Fokus auf Praktiken, die nicht das abgeschlossene Werk, sondern den gemeinsamen Prozess des Voneinander-Lernens unter Einbeziehung spezifischer Publika (z.B. aktivistischer Initiativen) fokussieren, die dem Kunstbetrieb zugrunde liegenden Infrastrukturen verändert werden können.

As a philosopher of science, Pierre Duhem is most often remembered as the earliest contributor to what became known as the Duhem-Quine thesis. This thesis casts doubt on our ability to isolate and test theories, and to choose between empirically equivalent rivals. By extension, it offers important criticism of the rationality of deductivist science. In contrast with the vast literature produced during the 20th century addressing the problem of empirical underdetermination of theories, little has been said on the viability of (...) the solution Duhem himself proposed to the problem: good sense. In this paper, we offer an analysis of two varieties of underdetermination, discuss when and why they matter, and how good sense is supposed to aid theory choice. We also look at two recent reconstructions of Duhemian good sense, and argue that one is to be favoured. (shrink)

On the basis of the concepts of culture industry and semiformation, this paper presents Adorno's dialectical perspective as it uncovers the objective determinations of the social realm, following the Marxist investigation of the social objectivity of the social forms of production. In this dialectic, the universal - as social submission or reification- is immanent and objectively present, which does not occur in Habermas' intersubjective and non-dialectical construction.A partir dos conceitos de indústria cultural e semiformação, procura-se apresentar a perspectiva dialética de (...)

Father Frederick Copleston is best known for his carefully crafted works History of Philosophy and Thomas Aquinas. Copleston’s most notable metaphysical thesis is his interpretation of the argument from contingency, which he sees as the superior choice for theists. He draws on Aquinas and distinguishes between causa fieri and causa esse to argue that God is a higher order cause of contingent causal series. Copleston presents God not as a temporal first cause, but an ontologically ultimate cause necessary to explain (...) a contingent universe. His contribution changed the way we read Aquinas. Copleston’s willingness to debate his thesis with different philosophical perspectives is illustrated by his acceptance to discuss God’s existence with Bertrand Russell, in 1948. This BBC radio debate epitomises the dispute between theists and atheists from the 1940s onwards. I undertake to expound and comment Copleston’s contribution to metaphysics, present relevant parts of the debate and provide criticism. (shrink)

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".

A pandemia de COVID-19 deu maior visibilidade ao trabalho de epidemiologistas, e em particular ao uso de modelos epidemiológicos. Projeções da expansão da doença, número de casos e o seu pico esperado, são amplamente divulgadas na mídia. Políticas de saúde pública, como medidas de isolamento social, são justificadas à população com base na necessidade de se ‘achatar a curva’, e evitar o colapso do sistema de saúde. Mas o público não é informado sobre os usos e limitações dos modelos. A (...) necessidade de recalibrarmos os modelos com novos dados e de revisarmos projeções também são pouco compreendidas e por vezes se tornam fonte de frustração, alimentando ceticismo para com a verdade científica. Neste artigo eu discuto brevemente de que maneira a reflexão filosófica sobre os usos dos modelos, e de suas propriedades epistêmicas – cognição, explicação e entendimento – pode mitigar esses problemas.

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.

The thesis of the priority of the object, essential to Adorno's non dogmatic materialism, is analyzed in its constitutive elements, as a criticism of idealism which is present mainly at the works Dialectic of enlightenment and Negative dialectic. As a criticism of idealism, particularly on the relationships between reason and experience as first developed from Kant to Hegel, the thesis is based on Lukács, Benjamin, and Horkheimer contributions and is embedded on the perspectives of Marx and Nietzsche. With its disruption (...) of symmetry between subject and object, the thesis of the priority of the object reveals the frailty of Habermas assertion, in his Philosophical discourse of modernity, of Adorno's and Horkheimer's skepticism towards reason. The present author argues that, in opposition to this claim, Adorno and Horkheimer contributed, with their new way of relating historical material and theoretical approach, to the analysis of the problem of reification in its relations to objectivity - as the non-identical - within the realm of reason, and not outside of it.Este artigo investiga a "Tese" do primado do objeto na obra de Theodor W.

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 impediment of individuals affected by mental illness at risk of suicide is well justified. But the impediment to rational suicide is complicated by the conflict between defending life and defending autonomy, as illustrated by the various philosophical approaches to the ethical dimension of suicide. In this article we argue that, insofar as punctual in nature and limited in scope, paternalistic intervention of the autonomous individual is also justified. To do so, we will use the distinction between shallow and deep (...) autonomy, as well as complicating factors from recent medical literature: the question of ambivalence and the cry for help model. We will also pay special attention to the ethical implications of new strategies for risk detection that use artificial intelligence applied to social network databases like Facebook. Although preliminary evidence suggests these are effective tools, their lack of transparency, regulation and consent puts civil liberties and rights at risk. (shrink)

For Herbert Marcuse, rationality today—amidst advanced capitalism and neoliberalism—is not confronted with an external irrational universal, as it was in the earlier period of liberalism. “General ‘harmony’” is converted into a goal that pacifies because it is technically feasible. Through the critique of everyday experiences, it is possible to distinguish between how individuals immediately appear in actual society and what is essential to society and humanity—by revealing the dependency on capital as a dehumanizing factor. Dependency remains hidden in the relations (...) between universals such as “capitalist society” and technical targets in the everyday lives of individuals. Only social movements that can decipher the rule of capitalism over everyday experiences have any chance of overcoming domination. (shrink)

The objective of the article is to examine the work of the "early Habermas" prior to the linguistic turn, localized in the preparatory studies at the Theorie des kommunikativen Handels and later works. We intend to investigate the essay Arbeit und Interaktion, of 1967, in which Habermas, discussing with Lukács, aims to legitimate his conception of history as emancipatory evolution of man as generic being, from Hegel's texts in Jena's time, besides suggesting a new reading of the young Marx.O objetivo (...) deste artigo consiste em examinar a obra do primeiro Habermas, anterior à virada lingüística, localizada a partir dos estudos preparatórios à Teoria da ação comunicativa.

Objective Bayesian epistemology invokes three norms: the strengths of our beliefs should be probabilities, they should be calibrated to our evidence of physical probabilities, and they should otherwise equivocate sufficiently between the basic propositions that we can express. The three norms are sometimes explicated by appealing to the maximum entropy principle, which says that a belief function should be a probability function, from all those that are calibrated to evidence, that has maximum entropy. However, the three norms of objective Bayesianism (...) are usually justified in different ways. In this paper we show that the three norms can all be subsumed under a single justification in terms of minimising worst-case expected loss. This, in turn, is equivalent to maximising a generalised notion of entropy. We suggest that requiring language invariance, in addition to minimising worst-case expected loss, motivates maximisation of standard entropy as opposed to maximisation of other instances of generalised entropy. Our argument also provides a qualified justification for updating degrees of belief by Bayesian conditionalisation. However, conditional probabilities play a less central part in the objective Bayesian account than they do under the subjective view of Bayesianism, leading to a reduced role for Bayes’ Theorem.

Varied evidence confirms more strongly than less varied evidence, ceteris paribus. This epistemological Variety of Evidence Thesis enjoys widespread intuitive support. We put forward a novel explication of one notion of varied evidence and the Variety of Evidence Thesis within Bayesian models of scientific inference by appealing to measures of entropy. Our explication of the Variety of Evidence Thesis holds in many of our models which also pronounce on disconfirmatory and discordant evidence. We argue that our models pronounce rightly. Against (...) a backdrop of failures of the Variety of Evidence Thesis, the intuitive case for the Variety of Evidence Thesis emerges strengthened. Our models do however not support the general case for the thesis since our explication of it fails to hold in certain cases. The parameter space of this failure is explored and an explanation for the failure is offered. (shrink)
