Este trabalho analisa idéias e atividades de Karl Popper referentes à controvérsia sobre interpretações e fundamentos da mecânica quântica. Atenção especial será dedicada às relações entre Popper e o físico italiano Franco Selleri, ao longo da década de 1980. A interpretação proposta por Popper para os enunciados probabilísticos como propensões, bem como seu ponto de vista realista, contribuíram para estabelecer uma ponte entre suas investigações filosóficas e a pesquisa física em mecânica quântica, ainda que sua idéia sobre as propensões tenha (...) tido uma pequena repercussão entre físicos, matemáticos e filósofos. Argumentaremos neste trabalho que a influência de Popper na física foi possível devido à legitimação, a partir de 1970, da controvérsia sobre os fundamentos da teoria quântica como uma genuína controvérsia científica com implicações filosóficas. Popper foi beneficiado por essa legitimação, mas ele também contribuiu para fazer aquela controvérsia chegar a um público mais amplo que aquele dos físicos envolvidos na própria controvérsia.I intend to present in this paper Karl Popper’s ideas and activities concerning the controversy about the interpretations and foundations of quantum mechanics. I will pay special attention to Popper’s relationship with the Italian physicist Franco Selleri, during the 1980s. Popper’s ideas of propensity and realism contributed to build a bridge between his philosophy and physical research in quantum mechanics, even if his idea of propensity has had a weak reception among physicists, mathematicians and philosophers. I will argue that Popper’s contributions to physics were possible due to the legitimization in the 1970s of the controversy about the foundations of quantum mechanics, a process which permitted a trading zone between physics and philosophy. Popper was benefited by that process, but he also contributed to give to that controversy a larger audience thanthat of the physicists involved in that controversy. (shrink)

This paper offers a contribution to debates around integrative aspects of systems biology and engages with issues related to the circumstances under which physicists look at biological problems. We use oral history as one of the methodological tools to gather the empirical material, conducting interviews with physicists working in systems biology. The interviews were conducted at several institutions in Brazil, Germany, Israel and the U.S. Biological research has been increasingly dependent on computational methods, high-throughput technologies, and multidisciplinary skills. Quantitative scientists (...) are joining biological departments and collaborations between physicists and biologists are particularly vigorous. This state of affairs raises a number of questions, such as: What are the circumstances under which physicists approach biological problems in systems biology? What kind of interdisciplinary challenges must be tackled? The paper suggests that, concerning physicists’ move to work on biological systems, there are common reasons to move, the transition must be understood in terms of degrees, physicists have a rationale for simplifying systems, and distinct conceptions of model and modeling strategies are recurrent. We identified problems regarding linguistic clarity and integration of epistemological aims. We conclude that cultural unconformities within the systems biology community have important consequences to the flow of scientific knowledge. (shrink)

In 1966 the Brazilian physicist Klaus Tausk (b. 1927) circulated a preprint from the International Centre for Theoretical Physics in Trieste, Italy, criticizing Adriana Daneri, Angelo Loinger, and Giovanni Maria Prosperi`s theory of 1962 on the measurement problem in quantum mechanics. A heated controversy ensued between two opposing camps within the orthodox interpretation of quantum theory, represented by Leon Rosenfeld and Eugene P. Wigner. The controversy went well beyond the strictly scientific issues, however, reflecting philosophical and political commitments within the (...) context of the Cold War, the relationship between science in developed and Third World countries, the importance of social skills, and personal idiosyncrasies.

Neste artigo, analisamos os desafios historiográficos relacionados à produção de biografias no âmbito da História da Ciência. Em especial, discutimos as ideias apresentadas pelo historiador francês Jacques Le Goff em seu livro São Luís, publicado em 1996. Essa análise, de natureza teórica e metodológica, é cotejada com o esboço panorâmico da biografia do físico norte-americano David Bohm, recentemente publicada sob o título David Bohm – A Life Dedicated to Understanding the Quantum World. O tema tem relevância também para a história (...) da ciência no Brasil, uma vez que nosso personagem lecionou na Universidade de São Paulo entre fins de 1951 e início de 1955. (shrink)

A pesquisa em informação quântica sugere uma íntima conexão entre o conceito de informação e a teoria quântica, mas essa conexão envolve nuances cuja análise é o objeto deste trabalho. A sabedoria comum nesse campo divide-se em duas grandes áreas, não excludentes entre si. Há os que são movidos pela possibilidade de uso da teoria quântica em um novo campo, o da computação, independentemente do esclarecimento de seus fundamentos, aqui incluído o conceito de "informação". Alguns consideram que estamos diante de (...) um grande problema conceitual sem resposta satisfatória no momento, enquanto que outros, dentre os que reconhecem a magnitude do problema, têm proposto formulações com a pretensão de solução do problema. Este artigo tem pretensões modestas. Não pretendemos aportar novas soluções ao problema, nem apoiar uma das soluções existentes. Temos a expectativa de através da análise histórico-conceitual do problema mapear as diversas possibilidades, apontando o que nos parecem ser aspectos fortes e fracos nessas possibilidades. Research in quantum information suggests a close connection between information and quantum theory. The aim of this article is to analyze nuances involved in this connection. Scientists in this field are divided into two overlapping camps. Some are motivated only by the use of quantum features to improve information processing, in spite of concerns about the foundations of the quantum theory, while others recognize deep conceptual problems of this theory, and attempt to solve them. This article has modest ambitions. It aims only to chart, by way of historical and conceptual analysis, the diverse possibilities available, indicating the strengths and weaknesses of each of them.

This authoritative biography addresses the life and work of the quantum physicist David Bohm. Although quantum physics is considered the soundest physical theory, its strange and paradoxical features have challenged - and continue to challenge - even the brightest thinkers. David Bohm dedicated his entire life to enhancing our understanding of quantum mysteries, in particular quantum nonlocality. His work took place at the height of the cultural/political upheaval in the 1950's, which led him to become the most notable American scientist (...) to seek exile in the last century. The story of his life is as fascinating as his ideas on the quantum world are appealing. (shrink)

The rising interest, in the late 20th century, in the foundations of quantum physics, a subject in which Franco Selleri has excelled, has suggested the fair question: how did it become so? The current answer says that experiments have allowed to bring into the laboratories some previous gedanken experiments, beginning with those about EPR and related to Bell’s inequalities. I want to explore an alternative view, by which there would have been, before Bell’s inequalities experimental tests, a change in the (...) views shared by physicists concerning the intellectual status of that issue. I will take three cases which will serve as the threads of our story: the connections between Bohm’s causal interpretation and Bell’s inequalities; Wigner’s ideas on the measurement problem; and finally Everett’s relative states formulation. In the end, I will discuss how those threads were gathered together by creating foundations of quantum physics as a field of research. (shrink)

Crucial to most research in physics, as well as leading to the development of inventions such as the transistor and the laser, quantum mechanics approaches its centenary with an impressive record. However, the field has also long been the subject of ongoing debates about the foundations and interpretation of the theory, referred to as the quantum controversy. This Oxford Handbook offers a historical overview of the contrasts which have been at the heart of quantum physics for the last 100 years. (...) Drawing on the wide-ranging expertise of several contributors working across physics, history, and philosophy, the handbook outlines the main theories and interpretations of quantum physics. It goes on to tackle the key controversies surrounding the field, touching on issues such as determinism, realism, locality, classicality, information, measurements, mathematical foundations, and the links between quantum theory and gravity. This engaging introduction is an essential guide for all those interested in the history of scientific controversies and history of quantum physics. It also provides a fascinating examination of the potential of quantum physics to influence new discoveries and advances in fields such quantum information and computing. (shrink)

This book tells the fascinating story of the people and events behind the turbulent changes in attitudes to quantum theory in the second half of the 20th century. The huge success of quantum mechanics as a predictive theory has been accompanied, from the very beginning, by doubts and controversy about its foundations and interpretation. This book looks in detail at how research on foundations evolved after WWII, when it was revived, until the mid 1990s, when most of this research merged (...) into the technological promise of quantum information. It is the story of the quantum dissidents, the scientists who brought this subject from the margins of physics into its mainstream. It is also a history of concepts, experiments, and techniques, and of the relationships between physics and the world at large, touching on themes such as the Cold War, McCarthyism, Zhdanovism, and the unrest of the late 1960s.

Este ensaio introdutório faz uma breve apresentação do tratado de óptica atribuído a Euclides de Alexandria, inserindo-o no contexto das teorias sobre a visão formuladas pelas doutrinas filosóficas antigas. Ressalta-se o antagonismo entre a análise geométrica da visão, empreendida por Euclides, e as considerações filosóficas acerca dos processos físicos subjacentes à sensação visual. Pretende-se mostrar que o objeto da óptica euclidiana é a percepção visual daquilo que Aristóteles denomina "sensível comum". This introductory essay provides an abridged presentation of the optical (...) treatise attributed to Euclid of Alexandria, placing it in the context of theories about vision formulated by the ancient philosophical doctrines. I emphasize the antagonism between the geometric analysis of vision, undertaken by Euclid, and the philosophical considerations about the physical processes underlying visual sensation. In addition, I aim to show that the object of Euclidean optics is the visual perception of what Aristotle calls "common sensible". (shrink)

John Lachs, Centennial Professor of Philosophy Emeritus, Vanderbilt University, passed away on 14 November 2023. Notably, he ends his book In Love with Life with a quote from George Santayana: “The time will doubtless come for each of us, if not for the universe at large, to cease from care; but our passage through life will have added a marvelous episode to the tale of things” (Lachs, In Love with Life 125). John’s life indeed was a marvelous episode. He was (...) born in Budapest, Hungary, on 17 July 1934, living through World War II as a child.

The question of the subject seems to occupy much of the current psychiatric/psychological landscape. Some theoreticians affirm that the subject or the self is an imaginary fiction, not a substantial entity in whose structure causes of psychological disorders and their respective antidotes are latent. “Subject,” they continue, “is what the vernacular speech says it is, that is, a self-reference marker that indexes human organisms’ sensory/motor singularity.” This marker, however, has nothing in common with a supposed metaphysical ethereal substrate, made up (...) of particles such as will, freedom, autonomy, ineffable consciousness, reason, emotions, desires, beliefs, judgments, aspirations, or interests.

This essay explores how the doctrine of the Resurrection informs theological reflection on reconciliation in post‐Apartheid South Africa. It begins by establishing the fragile and liminal state of reconciliation, despite the efforts of the Truth and Reconciliation Commission. It then argues that the Resurrection offers an ecstatic and relational understanding of the human, which in turn provides a basis for advancing claims regarding human dignity and well‐being. In conversation with the work of Oliver O'Donovan and James Alison on the Resurrection, (...) this view is further contextualized by incorporating insights from ubuntu and from the work of Judith Butler on grieving. The essay closes with proposals for how the church in post‐Apartheid South Africa can give witness to the Resurrection in its immediate life and work through advocacy and carrying on the politics of grieving.

O presente texto narra uma experiência de formação de alfabetizadores de jovens e adultos: uma alfabetização filosófica de 40 horas com 300 alfabetizadores em julho de 2022, como primeira etapa do Programa “Supera RN” em Pau dos Ferros, dentro da Política de Superação do Analfabetismo do Estado do Rio Grande do Norte (RN). O texto tematiza em que sentido a experiência de Alfabetização filosófica se inspira e ao mesmo tempo se diferencia do curso de Alfabetização oferecido por Paulo Freire (...) em Angicos em 1963. Inspirado na curiosidade e no compromisso de Paulo Freire com os esfarrapados do mundo, o conceito “alfabetização filosófica” propõe uma formação experiencial sustentada nas seguintes disposições: escutar atentamente o mundo humano e não humano que nos rodeia; pensar juntos com cuidado e calma; relacionarmo-nos cooperativa e não competitivamente com as ideias das outras pessoas; perguntarmo-nos, colocando em questão, nossa vida e a maneira como nos relacionamos com ela, num tempo especial, singular, suspendido; conversar como iguais na busca de enfrentar as exigências de nossa comunidade; inventar novas formas de estar com outras e outros. O texto apresenta como essas disposições foram pensadas e praticadas durante a alfabetização filosófica em Pau dos Ferros, RN, através de cinco princípios (perguntar; escutar; tempo de infância; igualdade; pensar juntos) e lança algumas perguntas sobre possíveis desdobramentos da alfabetização filosófica no campo de formação de professores.

Im Zentrum des Werkes von Michael Oakeshott (1901-1990) steht die Frage nach der Vernunft der Praxis und der Praxis der Vernunft. Dieses klassische Thema der praktischen Philosophie, das heute im Hintergrund verschiedener Debatten in Philosophie und Politikwissenschaft steht, leitete Oakeshott in seiner Auseinandersetzung mit der modernen Politik. Die in dem Sammelband vereinigten Beitrage bieten einen Uberblick uber die internationale Forschungslage; ihr gemeinsamer Angelpunkt ist Oakeshotts Praxisbegriff: Diskutiert wird seine praktische Bedeutung im Durchgang durch die grundlegenden politischen und gesellschaftlichen Problemfragen der (...) Gegenwart, seine theoretische Leistungsfahigkeit ist Gegenstand vergleichender Perspektiven, die vor allem die deutschen Zeitgenossen wie H. Arendt, H.-G. Gadamer, G. Simmel oder L.

Oliver Wendell Holmes, Jr, is considered by many to be the most influential American jurist. The voluminous literature devoted to his writings and legal thought, however, is diverse and inconsistent. In this study, Frederic R. Kellogg follows Holmes's intellectual path from his early writings through his judicial career. He offers a fresh perspective that addresses the views of Holmes's leading critics and explains his relevance to the controversy over judicial activism and restraint. Holmes is shown to be an original legal (...) theorist who reconceived common law as a theory of social inquiry and who applied his insights to constitutional law. From his empirical and naturalist perspective on law, with its roots in American pragmatism, emerged Holmes's distinctive judicial and constitutional restraint. Kellogg distinguishes Holmes from analytical legal positivism and contrasts him with a range of thinkers. (shrink)

The digitalisation of healthcare is transforming nursing practice, presenting unique opportunities and challenges that demand more than technical competence from nursing professionals. Despite the growing integration of digital tools, nursing remains in the ‘foothills of digital transformation’, with significant gaps in the critical and theoretical frameworks required to navigate this shift effectively. This article explores how Paulo Freire's critical pedagogy may address these gaps by fostering critical digital skills in nursing students. Drawing on Freire's concepts of problem‐posing education, (...) conscientization, dialogue and praxis, the article proposes a pedagogical model that encourages students to critically examine the socio‐political and ethical implications of digital tools within their practice. By aligning Freirean principles with contemporary nursing challenges, the article argues for a shift away from solely competency‐based frameworks toward educational approaches that promote reflective, dialogical, and ethically informed engagement with technology. The limitations of Freirean pedagogy, including its difficulty in evidencing direct outcomes, are discussed alongside its potential to cultivate a philosophically engaged nursing workforce capable of navigating the complexities of a digital healthcare environment and its associated impact on the profession. This approach underscores the importance of preserving nursing's core ethical and relational values while embracing the transformative potential of digital technologies. (shrink)

This book explores the cultures of philosophy and the law as they interact with neuroscience and biology, through the perspective of American jurist Oliver Wendell Holmes’ Jr., and the pragmatist tradition of John Dewey. Schulkin proposes that human problem solving and the law are tied to a naturalistic, realistic and an anthropological understanding of the human condition. The situated character of legal reasoning, given its complexity, like reasoning in neuroscience, can be notoriously fallible. Legal and scientific reasoning is to be (...) understood within a broader context in order to emphasize both the continuity and the porous relationship between the two. Some facts of neuroscience fit easily into discussions of human experience and the law. However, it is important not to oversell neuroscience: a meeting of law and neuroscience is unlikely to prove persuasive in the courtroom any time soon. Nevertheless, as knowledge of neuroscience becomes more reliable and more easily accepted by both the larger legislative community and in the wider public, through which neuroscience filters into epistemic and judicial reliability, the two will ultimately find themselves in front of a judge. A pragmatist view of neuroscience will aid and underlie these events. (shrink)

This essay builds on recent work by Susan Haack to suggest that Oliver Wendell Holmes Jr.’s conception of the common law was influenced by Darwinian evolution and classical pragmatism. This is no small claim: perceptions of what the common law is and does within the constitutional framework of the United States continue to be heavily debated. Holmes’s paradigm for the common law both revised and extended the models set forth by Sir Edward Coke, Thomas Hobbes, Sir Matthew Hale, and Sir (...) William Blackstone. Adding additional substance to Haack’s argument by pointing out passages in Holmes’s opinions and in his only book, The Common Law, that corroborate her claims about the particular features of Holmes’s pragmatism, this essay concludes by suggesting that, because of his connections with the classical pragmatists and his reverence for Emerson, Holmes is the best place to begin answering the famous question formulated by Stanley Cavell: “What’s the Use in Calling Emerson a Pragmatist?”.

The Pragmatism and Prejudice of Oliver Wendell Holmes, Jr. examines the varied categories scholars have used to describe the philosophy of Oliver Wendell Holmes, Jr. These include, “Jobbist,” Nihilist, Realist, Social Darwinist, Utilitarian, Positivist, Natural Law Theorist, and Pragmatist.

Oliver Wendell Holmes, Jr. is, arguably, the most important American jurist of the twentieth century, and his essay The Path of the Law, first published in 1898, is the seminal work in American legal theory. In it, Holmes detailed his radical break with legal formalism and created the foundation for the leading contemporary schools of American legal thought. He was the dominant source of inspiration for the school of legal realism, and his insistence on a practical approach to law and (...) legal analysis laid the basis for the realists' later concentration upon the pragmatic and empirical aspects of law and legal procedures. This volume brings together some of the most distinguished legal scholars from the United States and Canada to examine competing understandings of The Path of the Law and its implications for contemporary American jurisprudence. For the reader's convenience, the essay is republished in an Appendix. (shrink)

By any measure, Oliver Wendell Holmes, Jr., led a full and remarkable life. He was tall and exceptionally attractive, especially as he aged, with piercing eyes, a shock of white hair, and prominent moustache. He was the son of a famous father, a thrice-wounded veteran of the Civil War, a Harvard-educated member of Brahmin Boston, the acquaintance of Longfellow, Lowell, and Emerson, and for a time a close friend of William James. He wrote one of the classic works of American (...) legal scholarship, The Common Law, and he served with distinction on the Supreme Court of the United States. He was actively involved in the Court's work into his nineties. In Justice Oliver Wendell Holmes, G. Edward White, the acclaimed biographer of Earl Warren and one of America's most esteemed legal scholars, provides a rounded portrait of this remarkable jurist. We see Holmes's early life in Boston and at Harvard, his ambivalent relationship with his father, and his harrowing service during the Civil War. White examines Holmes's curious, childless marriage and he includes new information on Holmes's relationship with Clare Castletown. White not only provides a vivid portrait of Holmes's life, but examines in depth the inner life and thought of this preeminent legal figure. There is a full chapter devoted to The Common Law, for instance, and throughout the book, there is astute commentary on Holmes's legal writings. Indeed, White reveals that some of the themes that have dominated 20th-century American jurisprudence--including protection for free speech and the belief that "judges make the law"--originated in Holmes's work. Perhaps most important, White suggests that understanding Holmes's life is crucial to understanding his work, and he continually stresses the connections between Holmes's legal career and his personal life. For instance, his desire to distinguish himself from his father and from the "soft" literary culture of his father's generation drove him to legal scholarship of a particularly demanding kind. White's biography of Earl Warren was hailed by Anthony Lewis on the cover of The New York Times Book Review as "serious and fascinating," and The Los Angeles Times noted that "White has gone beyond the labels and given us the man." In Justice Oliver Wendell Holmes, White has produced an equally serious and fascinating biography, one that again goes beyond the labels and gives us the man himself. (shrink)
