How Classical Particles Emerge From the Quantum World.Dennis Dieks &Andrea Lubberdink -2011 -Foundations of Physics 41 (6):1051-1064.detailsThe symmetrization postulates of quantum mechanics (symmetry for bosons, antisymmetry for fermions) are usually taken to entail that quantum particles of the same kind (e.g., electrons) are all in exactly the same state and therefore indistinguishable in the strongest possible sense. These symmetrization postulates possess a general validity that survives the classical limit, and the conclusion seems therefore unavoidable that even classical particles of the same kind must all be in the same state—in clear conflict with what we know about (...) classical particles. In this article we analyze the origin of this paradox. We shall argue that in the classical limit classical particles emerge, as new entities that do not correspond to the “particle indices” defined in quantum mechanics. Put differently, we show that the quantum mechanical symmetrization postulates do not pertain to particles, as we know them from classical physics, but rather to indices that have a merely formal significance. This conclusion raises the question of whether many discussions in the literature about the status of identical quantum particles have not been misguided. (shrink)
Molecular Codes Through Complex Formation in a Model of the Human Inner Kinetochore.Dennis Görlich,Gabi Escuela,Gerd Gruenert,Peter Dittrich &Bashar Ibrahim -2014 -Biosemiotics 7 (2):223-247.detailsWe apply molecular code theory to a rule-based model of the human inner kinetochore and study how complex formation in general can give rise to molecular codes. We analyze 105 reaction networks generated from the rule-based inner kinetochore model in two variants: with and without dissociation of complexes. Interestingly, we found codes only when some but not all complexes are allowed to dissociate. We show that this is due to the fact that in the kinetochore model proteins can only bind (...) at kinetochores by attaching to already attached proteins and cannot form complexes in free solution. Using a generalized linear mixed model we study which centromere protein can take which role in a molecular code . By this, associations between CENPs and code roles are found. We observed that CenpA is a major risk factor while CenpQ is a major protection factor . Finally we show, using an abstract model of copolymer formation, that molecular codes can also be realized solely by the formation of stable complexes, which do not dissociate. For example, with particular dimers as context a molecular code mapping from two different monomers to two particular trimers can be realized just by non-selective complex formation. We conclude that the formation of protein complexes can be utilized by the cell to implement molecular codes. Living cells thus facilitate a subsystem allowing for an enormous flexibility in the realization of mappings, which can be used for specific regulatory processes, e.g. via the context of a mapping.

Equality and Priority.Dennis Mckerlie -1994 -Utilitas 6 (1):25.detailsMoral egalitarianism will depend on one of two basic ideas. The first is the idea of equality itself. We might believe that it is a good thing if different people have equal shares of resources, or if their lives score equally well in terms of whatever makes lives valuable, at least if there is no reason based on some other moral value for one person to do better than the other. Equality is a relationship between the lives of different people. (...) This version of egalitarianism claims that the existence of the relationship makes an outcome better. It attributes value to relations between lives rather than to the content of lives. (shrink)
Special relativity and the flow of time.Dennis Dieks -1988 -Philosophy of Science 55 (3):456-460.detailsN. Maxwell (1985) has claimed that special relativity and "probabilism" are incompatible; "probabilism" he defines as the doctrine that "the universe is such that, at any instant, there is only one past but many alternative possible futures". Thus defined, the doctrine is evidently prerelativistic as it depends on the notion of a universal instant of the universe. In this note I show, however, that there is a straightforward relativistic generalization, and that therefore Maxwell's conclusion that the special theory of relativity (...) should be amended is unwarranted. I leave open the question whether or not probabilism (or the related doctrine of the flow of time) is true, but argue that the special theory of relativity has no fundamental significance for this question.

Von Neumann’s impossibility proof: Mathematics in the service of rhetorics.Dennis Dieks -2017 -Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 60:136-148.detailsAccording to what has become a standard history of quantum mechanics, von Neumann in 1932 succeeded in convincing the physics community that he had proved that hidden variables were impossible as a matter of principle. Subsequently, leading proponents of the Copenhagen interpretation emphatically confirmed that von Neumann's proof showed the completeness of quantum mechanics. Then, the story continues, Bell in 1966 finally exposed the proof as seriously and obviously wrong; this rehabilitated hidden variables and made serious foundational research possible. It (...) is often added in recent accounts that von Neumann's error had been spotted almost immediately by Grete Hermann, but that her discovery was of no effect due to the dominant Copenhagen Zeitgeist. We shall attempt to tell a more balanced story. Most importantly, von Neumann did not claim to have shown the impossibility of hidden variables tout court, but argued that hidden-variable theories must possess a structure that deviates fundamentally from that of quantum mechanics. Both Hermann and Bell appear to have missed this point; moreover, both raised unjustified technical objections to the proof. Von Neumann's conclusion was basically that hidden-variables schemes must violate the "quantum principle" that all physical quantities are to be represented by operators in a Hilbert space. According to this conclusion, hidden-variables schemes are possible in principle but necessarily exhibit a certain kind of contextuality. As we shall illustrate, early reactions to Bohm's theory are in agreement with this account. Leading physicists pointed out that Bohm's theory has the strange feature that particle properties do not generally reveal themselves in measurements, in accordance with von Neumann's result. They did not conclude that the "impossible was done" and that von Neumann had been shown wrong. (shrink)
Probability in modal interpretations of quantum mechanics.Dennis Dieks -2007 -Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 38 (2):292-310.detailsModal interpretations have the ambition to construe quantum mechanics as an objective, man-independent description of physical reality. Their second leading idea is probabilism: quantum mechanics does not completely fix physical reality but yields probabilities. In working out these ideas an important motif is to stay close to the standard formalism of quantum mechanics and to refrain from introducing new structure by hand. In this paper we explain how this programme can be made concrete. In particular, we show that the Born (...) probability rule, and sets of definite-valued observables to which the Born probabilities pertain, can be uniquely defined from the quantum state and Hilbert space structure. We discuss the status of probability in modal interpretations, and to this end we make a comparison with many-worlds alternatives. An overall point that we stress is that the modal ideas define a general framework and research programme rather than one definite and finished interpretation. (shrink)
Digital well-being under pandemic conditions: catalysing a theory of online flourishing.Matthew J.Dennis -2021 -Ethics and Information Technology 23 (3):435-445.detailsThe COVID-19 pandemic has catalysed what may soon become a permanent digital transition in the domains of work, education, medicine, and leisure. This transition has also precipitated a spike in concern regarding our digital well-being. Prominent lobbying groups, such as the Center for Humane Technology, have responded to this concern. In April 2020, the CHT has offered a set of ‘Digital Well-Being Guidelines during the COVID-19 Pandemic.’ These guidelines offer a rule-based approach to digital well-being, one which aims to mitigate (...) the effects of moving much of our lives online. The CHT’s guidelines follow much recent interest in digital well-being in the last decade. Ethicists of technology have recently argued that character-based strategies and redesigning of online architecture have the potential to promote the digital well-being of online technology users. In this article, I evaluate the CHT’s rule-based approach, comparing it with character-based strategies and approaches to redesigning online architecture. I argue that all these approaches have some merit, but that each needs to contribute to an integrated approach to digital well-being in order to surmount the challenges of a post-COVID world in which we may well spend much of our lives online.

A Kantian moral duty for the soon-to-be demented to commit suicide.Dennis R. Cooley -2007 -American Journal of Bioethics 7 (6):37 – 44.detailsIt has been argued that, on Kantian grounds, pedophiles, rapists and murderers are morally obligated to take their own lives prior to committing a violent action that will end their moral agency. That is, to avoid destroying the agent's moral life by performing a morally suicidal action, the agent, while he still is a moral agent, should end his body's life. Although the cases of dementia and the morally reprehensible are vastly different, this Kantian interpretation might be useful in the (...) debate on the permissibility of suicide for those facing dementia's effects. If moral agents have a duty to act as moral agents, then those who will lose their moral identity as moral agents have an obligation to themselves to end their physical lives prior to losing their dignity as persons.

Quantum Reality, Perspectivalism and Covariance.Dennis Dieks -2019 -Foundations of Physics 49 (6):629-646.detailsPaul Busch has emphasized on various occasions the importance for physics of going beyond a merely instrumentalist view of quantum mechanics. Even if we cannot be sure that any particular realist interpretation describes the world as it actually is, the investigation of possible realist interpretations helps us to develop new physical ideas and better intuitions about the nature of physical objects at the micro level. In this spirit, Paul Busch himself pioneered the concept of “unsharp quantum reality”, according to which (...) there is an objective non-classical indeterminacy—a lack of sharpness—in the properties of individual quantum systems. We concur with Busch’s motivation for investigating realist interpretations of quantum mechanics and with his willingness to move away from classical intuitions. In this article we try to take some further steps on this road. In particular, we pay attention to a number of prima facie implausible and counter-intuitive aspects of realist interpretations of unitary quantum mechanics. We shall argue that from a realist viewpoint, quantum contextuality naturally leads to “perspectivalism” with respect to properties of spatially extended quantum systems, and that this perspectivalism is important for making relativistic covariance possible.

Quantum statistics, identical particles and correlations.Dennis Dieks -1990 -Synthese 82 (1):127 - 155.detailsIt is argued that the symmetry and anti-symmetry of the wave functions of systems consisting of identical particles have nothing to do with the observational indistinguishability of these particles. Rather, a much stronger conceptual indistinguishability is at the bottom of the symmetry requirements. This can be used to argue further, in analogy to old arguments of De Broglie and Schrödinger, that the reality described by quantum mechanics has a wave-like rather than particle-like structure. The question of whether quantum statistics alone (...) can give rise to empirically observable correlations between results of distant measurements is also discussed. (shrink)
Reduction and understanding.Dennis Dieks &Henk W. de Regt -1998 -Foundations of Science 3 (1):45-59.detailsReductionism, in the sense of the doctrine that theories on different levels of reality should exhibit strict and general relations of deducibility, faces well-known difficulties. Nevertheless, the idea that deeper layers of reality are responsible for what happens at higher levels is well-entrenched in scientific practice. We argue that the intuition behind this idea is adequately captured by the notion of supervenience: the physical state of the fundamental physical layers fixes the states of the higher levels. Supervenience is weaker than (...) traditional reductionism, but it is not a metaphysical doctrine: one can empirically support the existence of a supervenience relation by exhibiting concrete relations between the levels. Much actual scientific research is directed towards finding such inter-level relations. It seems to be quite generally held that the importance of such relations between different levels is that they are explanatory and give understanding: deeper levels provide deeper understanding, and this justifies the search for ever deeper levels. We shall argue, however, that although achieving understanding is an important aim of science, its correct analysis is not in terms of relations between higher and lower levels. Connections with deeper layers of reality do not generally provide for deeper understanding. Accordingly, the motivation for seeking deeper levels of reality does not come from the desire to find deeper understanding of phenomena, but should be seen as a consequence of the goal to formulate ever better, in the sense of more accurate and more-encompassing, empirical theories.

Ancient Traditions, Modern Constructions: Innovation, Continuity, and Spirituality on the Powwow Trail.KelleyDennis F. -2012 -Journal for the Study of Religions and Ideologies 11 (33):107-136.detailsIn contemporary Indian Country, the majority of people who identify as “Indian” fall into the “urban” category: away from traditional lands and communities, in cities and towns wherein the opportunities to live one’s identity as Native can be restricted, and even more so for American Indian religious practice and activity. This article will explore a possible theoretical model for discussing the religious nature of urban Indians, using aspects of the contemporary powwow as exemplary, and suggest ways in which the discourse (...) on Native American religious practices can inform the larger discussion of religion in general by implying a comparative direction between urban Indians and other religious actors in American secular society.

Balancing Ethics and Shareholder Returns.Dennis Proffitt -2011 -Journal of Business Ethics Education 8 (1):181-198.details“Balancing Ethics and Shareholder Returns: The Case of Google in China” provides a timely example of a well-known firm who, in their attempt to act in an ethical manner, generated tremendous financial harm to their shareholders. It provides an interesting counterpoint to the assertion in the literature that shareholder wealth maximization provides an ethical basis for all business decisions. Google is a firm that many students know and admire, and this should spark interest in the case. It can be assigned (...) in the early stages of a corporate finance class, where the topic of discussion is the goal of the firm, or in a business ethics class, where the goal of the firm is evaluated. The case provides an opportunity to evaluate the ethical basis for Google’s actions, as well as the resulting impact on shareholder returns. The case may also represent a real-life counterpoint to the oft-repeated maxim that “Good ethics is good business”. Information in the case was compiled from secondary sources. (shrink)
Keeping Pace with the Movement of Life: On Words and Music.Dennis J. Schmidt -2013 -Research in Phenomenology 43 (2):193-203.detailsThe largest purpose of this paper is to ask about how it is that life is re-presented by us. The argument is that life should be considered as a matter not of a collection of objects, but of a movement, of time. Furthermore, the claim is that the conceptual language of philosophy has the liability of ossifying this movement of life but that music, which is time and movement above all, is able to keep pace with this movement of life.
Régis and Rohault.Dennis des Chene -2006 - In Donald Rutherford,The Cambridge companion to early modern philosophy. New York: Cambridge University Press.detailsIn the history of philosophy, Jacques Rohault and Pierre-Sylvain Régis bear a twofold burden. They are professed followers, epigones. Worse yet, the natural philosophy they teach has been consigned to the Tartarus of fable: not a theory that failed, but something that failed even to be a theory. In the years in which they were turning Cartesianism into a system, Newton and Huygens were preparing its demise. Its empirical claims were refuted, its mathematics was rendered obsolete by the calculus, its (...) vortices and channelled magnetic particles met with the same rough justice Descartes meted out to Scholastic forms and qualities. Canonical history has little use for such figures. It prefers originals. Yet if ideas and arguments are not to seem to pass magically from one great mind to the next, we must have some account of the channels through which what was once novel and unique sediments into cliché and common ground. Those channels are not without bias and noise. Inevitably, currents from different streams meet and mix more or less coherently in the works of secondary figures, especially in the competitive intellectual world of the later seventeenth century, with its sometimes ferocious polemics fuelled by religious and political opposition. Cartesianism became a movement and—to use Leibniz’s word—a sect, divided within by disputes over the legacy of its founder, and facing opposition without from steadfast Aristotelians, pious theologians, and the avant garde of the new science. In Régis and Rohault Descartes’ legacy took the outward form of “system”. They present themselves as reworking Cartesian concepts and arguments into something coherent and comprehensive. Rohault, the more modest of the two, aims to reform the teaching of physics, still weighed down by the dead hand of Aristotle. He retains for the old philosophy only what is true and conjoin it with the new physics of Descartes, in whom France is no less fortunate than Greece once was in Aristotle (Rohault 1718, “Præfatio”)..

On Hegel's Critique of Kant's Subjectivism in the Transcendental Deduction.Dennis Schulting -2017 - InKant's Radical Subjectivism: Perspectives on the Transcendental Deduction. London, UK: Palgrave-Macmillan. pp. 341-370.detailsIn this chapter, I expound Hegel’s critique of Kant, which he first and most elaborately presented in his early essay Faith and Knowledge (1802), by focusing on the criticism that Hegel levelled against Kant’s (supposedly) arbitrary subjectivism about the categories. This relates to the restriction thesis of Kant’s transcendental idealism: categorially governed empirical knowledge only applies to appearances, not to things in themselves, and so does not reach objective reality, according to Hegel. Hegel claims that this restriction of knowledge to (...) appearances is unwarranted merely on the basis of Kant’s own principle of transcendental apperception, and just stems from Kant’s empiricist bias. He argues that Kant’s principle of apperception as the foundational principle of knowledge is in fact incompatible with his empiricism. Hegel rightly appraises the centrality of transcendental apperception for the constitution of objectivity. But he is wrong about its incompatibility with Kant’s empirical realism. By virtue of a misapprehension of the formal distinction between the accompanying ‘I think’, i.e. the analytical principle of apperception, and what Hegel calls “the true ‘I’” of the original-synthetic unity of apperception, Hegel unjustifiably prises apart the productive imagination, which is supposedly this “true ‘I’”, and the understanding, which is supposedly just a derivative, subjective form of the productive imagination; the latter, according to Hegel, is Reason or Being itself, and is the truly objective. This deflationary reading of the understanding, which hypostatises the imagination as the supreme principle, rests on a distortion of key elements of Kant’s theory of apperception. In this chapter, I show that Hegel’s charge of inconsistency against Kant, namely, Hegel’s claim that the principle of apperception as the highest principle of cognition does not comport with Kant’s restriction thesis, is the direct consequence of a psychological misreading of Kant’s subjectivism.

The Action of Centripetal and Centrifugal Forces in Religious Discourse about People with Disabilities: Reflections Based on Bakhtin and the Circle.Dennis Souza da Costa &Ivana Siqueira Teixeira -2024 -Bakhtiniana 19 (2):e63573p.detailsRESUMO Este artigo analisa a atuação das forças centrípetas e centrífugas em enunciados da esfera religiosa que evidenciam cosmovisões do segmento cristão evangélico acerca da deficiência. Para tanto, selecionamos um vídeo disponível na plataforma YouTube contendo enunciados dos apresentadores Tito Rocha e Leandro Quadros relativos à temática da deficiência, bem como a resposta de uma internauta acerca do posicionamento desses sujeitos. A reflexão teórico-metodológica fundamenta-se na orientação dialógica da linguagem, sobretudo nas considerações acerca das relações dialógicas, vozes e forças centrípetas (...) e centrífugas. Também recorremos a estudos sobre cosmovisão, inclusão da pessoa com deficiência, discurso religioso e teologia cristã. Os resultados indicam que os discursos dos apresentadores refletem e refratam uma cosmovisão cristã que unifica o entendimento da deficiência como resultado da condenação divina ocasionada pelo pecado. O comentário da internauta, por sua vez, apresenta movimentos de centralização e dispersão dessa perspectiva cristã. (shrink)

Springer. pp. 315--333.detailsWe take another look at Reichenbach’s 1920 conversion to conventionalism, with a special eye to the background of his ‘conventionality of distant simultaneity’ thesis. We argue that elements of Reichenbach earlier neo-Kantianism can still be discerned in his later work and, related to this, that his conventionalism should be seen as situated at the level of global theory choice. This is contrary to many of Reichenbach’s own statements, in which he declares that his conventionalism is a consequence of the arbitrariness (...) of coordinative definitions. (shrink)
Skepticist philosophy as ethnomethodology.AlexDennis -2003 -Philosophy of the Social Sciences 33 (2):151-173.detailsEthnomethodology is in trouble, its conceptual apparatus prone to indifference or misunderstanding both from "conventional" sociologists and from its own practitioners.

Ingenium, Memory Art, and the Unity of Imaginative Knowing in the Early Descartes.Dennis L. Sepper -1993 - In Stephen Voss,Essays on the philosophy and science of René Descartes. New York: Oxford University Press.detailsThis chapter proposes to take the first few steps toward understanding the problematics of imagination in Descartes. It aims to show that in writings preceding the Regulae, Descartes conceived imagination as the chief faculty in the work of cognition, indeed the chief faculty for unifying knowledge. In this light the Regulae appears not simply as an early formulation of the principles of method, but as the tension-filled outcome of an attempt to think through the heuristic and cognitive competencies of imagination (...) on the basis of a human psychology strongly correlated with human physiology. Although the inadequacies of this attempt ultimately led to the cognitive demotion of imagination, there are nevertheless reasons for thinking that the early framework, shaped by the primacy of imagination, was not so much rejected as transformed in Descartes' mature work. The chapter further explains that imagination is the foundation of physics and mathematics and that it is both corporeal and spiritual. In addition imagination also serves as agent of all intelligent perception and the chief faculty for rising to higher level of spiritual truths. It further explains phantasia, a crucial organ of the brain where images occur, either derived from the senses, memory or from the intellect. (shrink)

Values for a Post-Pandemic Future.Matthew JamesDennis,Georgy Ishmaev,Steven Umbrello &Jeroen van den Hoven (eds.) -2022 - Cham: Springer.detailsThis Open Access book shows how value sensitive design (VSD), responsible innovation, and comprehensive engineering can guide the rapid development of technological responses to the COVID-19 crisis. Responding to the ethical challenges of data-driven technologies and other tools requires thinking about values in the context of a pandemic as well as in a post-COVID world. Instilling values must be prioritized from the beginning, not only in the emergency response to the pandemic, but in how to proceed with new societal precedents (...) materializing, new norms of health surveillance, and new public health requirements. -/- The contributors with expertise in VSD bridge the gap between ethical acceptability and social acceptance. By addressing ethical acceptability and societal acceptance together, VSD guides COVID-technologies in a way that strengthens their ability to fight the virus, and outlines pathways for the resolution of moral dilemmas. This volume provides diachronic reflections on the crisis response to address long-term moral consequences in light of the post-pandemic future. Both contact-tracing apps and immunity passports must work in a multi-system environment, and will be required to succeed alongside institutions, incentive structures, regulatory bodies, and current legislation.

Freedom and Creation in Schelling.Henning Tegtmeyer &Dennis Vanden Auweele (eds.) -2022 - Stuttgart-Bad Canstatt: Frommann-Holzboog.detailsThis volume is dedicated to the exploration of the connection between freedom and creation in Schelling’s late philosophy. It contains contributions of internationally renowned and younger Schelling scholars from several countries. The scholarly interest in Schelling’s late philosophy has considerably increased during the last decades. Together with the rising number of available primary texts and translations, this has led, among other things, to a received scholarly view of Schelling’s Erlangen, Munich, and Berlin years that partly challenges and partly rejects many (...) claims of the older literature on Schelling. For example, his late philosophy is not conceived as a straightforward defence of orthodox theism anymore but seen within the context of his philosophical development, with a focus on the continuity between his early, middle, and late philosophy. The concepts of freedom and creation occupy a central position in these studies. The present volume examines the complex interrelations between these two concepts in detail, in a well-balanced combination of exegesis, systematic reconstruction and philosophical analysis. (shrink)
The unconscious and Eduard von Hartmann.Dennis N. Kenedy Darnoi -1968 - The Hague,: Martinus Nijhoff.detailsNo man can live without ideas, for every human action, internal or external, is of necessity enacted by virtue of certain ideas. In these ideas a man believes; they guide his actions, and ultimately his whole life. Study of these ideas and principles is one of the distinctive tasks of the history of philosophy. But were we to restrict the field of interest of the history of philosophy to a mere detached academic "cataloguing" of past ideas, the history of philosophy (...) itself would have joined long ago the interminable line of barren catalogued ideas. The study of the wisdom of past ages, however, is very much alive. Not only is it alive, but in the words ot Wilhelm Dilthey: "What man is, he learns through history. "l Thus, the culture of every generation is inevitably related, whether thetically or antithetically, to the previous one, and the politi cal and economic struggles of any present are always the consequences of an earlier and perhaps even fiercer battle of ideas.

John Muir and the origin of Yosemite Valley.Dennis R. Dean -1991 -Annals of Science 48 (5):453-485.detailsThough virtually unknown before 1851, the exceptionally scenic Yosemite Valley of California soon attracted continuing attention as a geological anomaly. J. D. Whitney, state geologist and Harvard professor, advocated a tectonic theory of its origin. Despite its seemingly official status, Whitney's theory even failed to convince some of his own subordinates. An unexpectedly effective dissenter not associated with Whitney was John Muir, then a tatterdemalion vagrant. Though the two men never met, conflict between their inflexible and mutually exclusive geological theories (...) persisted well into the twentieth century. Eventually, both dogmatists were proved wrong, but Muir had come closer to what we now accept. Several geological and geomorphological issues of importance entered into later discussions of Yosemite. The whole controversy, moreover, illuminates such further issues as the influence of preconceptions on theorizing, the role of authority in science, and the interactions of professionals with amateurs.
