This article discusses the topic of algorithmic personalization and the creation of the so-called “filter bubble” effect, which is often understood as one of the most problematic influences of artificial intelligence on democratic social order. The author suggests that focusing on the issue of information diversity, which had far-reaching effect on the empirical research that tried to quantitatively measure and systematically prove the existence of the filter bubbles, was the wrong starting point for the discussion on the application of algorithmic (...) personalization. It has drawn our attention away from the deeper issue: habit. Habitual adaptation of algorithmic personalization, namely, stands in essential contradiction to the ideal image of a non-adaptive public sphere, upon which democratic societies should be based. Focusing on habitual adaptation could also explain why users addictively stick to certain kinds of information, even if they are not caught in an isolated chamber. (shrink)

Nicolas d'Autrécourt (c. 1298-1369) is one of the most daring thinkers in the history of philosophy, and Zénon Kaluza, who has devoted to him nearly thirty years of study, presents him to us through his sources, his doctrines and his manuscripts. The reader will find studies on some of the most relevant philosophical doctrines (such as perception, the final causality, the categories and the eternity of the world) as well as a new edition of the Prologues of the Exigit ordo, (...) enriched with a running commentary. The texts gathered here-some of which have been published previously but are difficult to access and others which have been unpublished until now-reveal a philosopher who wished to free philosophy from institutional constraints and dared to criticize Aristotle's metaphysics, at the risk of upsetting traditions and contradicting the dogmas of the faith, and who was condemned by the theological authorities of his time. Nicolas d'Autrécourt (c. 1298-1369) est l'un des penseurs les plus audacieux de l'histoire de la philosophie, et Zénon Kaluza, qui lui a consacré près de trente ans d'études, nous le fait découvrir par ses sources, ses doctrines et ses manuscrits. Ce livre propose notamment des analyses sur des thèmes importants (tels que la perception, la causalité finale, les catégories ou l'éternité du monde) ainsi qu'une nouvelle édition des Prologues de l'Exigit ordo, enrichie d'un commentaire suivi. Les études-dont certaines sont parues mais difficiles d'accès et d'autres sont inédites-dévoilent la figure d'un philosophe désirant de libérer la philosophie des contraintes institutionnelles et de critiquer la métaphysique d'Aristote, au risque de bouleverser les traditions, de contredire les dogmes de la foi et se voir condamner par les autorités théologiques de son temps.

In this article, we argue that Deleuze's philosophy could be understood as anarchistic in a specifically defined meaning. The imperative of immanence of thought, which we explicate mainly through the reading of Deleuze's Spinoza, on the one hand establishes indivisibility between theory and practice and on the other hand paradoxically orders disobedience. We argue for a thought that is immanent, adequate with its inner practice, for thought that cannot be forced. That is the basis on which we combine the reading (...) of Deleuze, Spinoza, Nietzsche and some basic ideas from the contemporary anarchistic movement and the anarchistic tradition. We do not try to argue for a certain form of political action. Our goal is to establish a field of thought, that is by its innermost ontological principles anarchistic: practice must be accompanied by its own theory. Adequate thought cannot be forced. This is a necessary condition for each consistent practice-theory. (shrink)

The article presents the concept of evil, as developed in the literary as well as philosophical works of Albert Camus. After a short, preliminary notice on the relationship between literature and evil, the article presents two spheres, in which the problem of evil was grasped by the author of The Rebel. In the main part of the article, the complexity of the problem of evil, as represented by Jean-Baptiste Clamence from The Fall is shown. It is seen as a development (...) of the concept of evil from The Plague, with the potency to disseminate onto others. It is also perceived, as something resulting from severe trauma of the main character. In conclusion, I claim, that the problem of evil, as experienced by Clamence may be understood as a still relevant metaphor of contemporary culture, struggling with passivity against the rise of social evil.

Coming Back to the Absurd is a celebration of the enduring significance and impact of Albert Camus's first philosophical essay The Myth of Sisyphus. This collection of essays, from some of the world's leading Camus scholars, examines Camus's unique contribution to philosophy through The Myth since its publication.

Certains penseurs médiévaux jugeaient la philosophie incapable de juger et d'interpréter la parole révélée donc supérieure. Pour d'autres, elle gardait son prestige antique et pouvait les mener à la perfection et à la félicité. Ces contributions étudient non pas la philosophie du Moyen âge dans son ensemble, ce qui n'est pas possible, mais des personnalités particulières, dont des théologiens.

This paper explores the program of theology of science proposed by renowned Polish physicist and philosopher, Michael Heller, with a particular focus on its ontological dimensions through the lens of Trinitarian theology. Firstly, an overview of the status and current discussions of theology of science is presented. Next, drawing on Heller's key texts the Trinitarian doctrine is used to enhance the intelligibility of the Universe, wherein the dynamic interplay of unity, diversity, and relationality is mirrored in the structure of physical (...) reality itself. Most importantly, however, we examine how Heller's theological perspective thus equipped provides justification for the specificity of the method of science itself, thereby revealing new dimensions of relations between science and theology. Through critical engagement with Heller's thought, this paper seeks ultimately to illuminate the profound implications of a Trinitarian perspective in his theology of science, shedding light on the interconnectedness of Christian doctrine and ontology in shaping our understanding of the universe and its underlying structure.

I examine the relation between explanation and unification in both the original Kaluza–Klein theory, which originated in the works of Theodor Kaluza and Oskar Klein in the 1920s, and in the modern Kaluza–Klein theories which date back to the late 1970s and which are still considered by the majority of the physics community to be the best hope for a complete unified theory of all fundamental interactions. I use the conclusions of this case study to assess the merits of Philip (...) Kitcher's account of explanation as unification. I also draw lessons about physicists’ pursuit of the higher dimensional unification of the fundamental forces of nature. (shrink)

In this chapter I discuss the attempts by Theodor Kaluza [Kaluza, T., 1921. Zum Unitätproblem der Physik. Sitzungsber. der K. Ak. der Wiss. zu Berlin, 966–972] and by Oskar Klein [Klein, O., 1926a. Quantentheorie und fünfdimensionale Relativitätstheorie. Zeitschrift für Physik 37 (12), 895–906; Klein, O., 1926b. The atomicity of electricity as a quantum theory law. Nature 118, 516], respectively, to unify electromagnetism and general relativity within a five-dimensional Riemannian manifold. I critically compare Kaluza's results to Klein's. Klein's theory possesses more (...) explanatory power and unificatory strength and uses less types of brute facts than Kaluza's. The characteristic feature of Klein's theory is that it relies on an extrinsic element of unification, i.e. the wavefunction behavior, which is not intrinsic to EM or GR. Finally, I compare and discuss Kaluza's and Klein's theories in the context of Tim Maudlin's [Maudlin, T., 1996. On the unification of physics. Journal of Philosophy 93 (3), 129–144] ranking of unification and I clarify in what sense they constitute counterexamples to some of Margaret Morrison's [Morrison, M., 2000. Unifying Scientific Theories: Physical Concepts and Mathematical Structures. Cambridge University Press] assertions about unification. (shrink)

In his search for a unified field theory that could undercut quantum mechanics, Einstein considered five-dimensional classical Kaluza-Klein theory. He studied this theory most intensively during the years 1938-1943. One of his primary objectives was finding a non-singular particle solution. In the full theory this search got frustrated, and in the x 5 -independent theory Einstein, together with Pauli, argued it would be impossible to find these structures.

After the unexpected death of Professor Józef Kałuża at the age of 74 on the 26th of July 2003, not only Polish neuropathology but also Polish philosophy of medical investigations lost one of its most renowned minds. Beginning in 1949, Professor Kałuża studied medical sciences for five years at the Medical Faculty of the Jagiellonian University in Cracow. He did his Ph.D. thesis in neuropathology in the Department of Neuropathology of the Polish Academy of Science. In 1962 he (...) received a Rockefeller Foundation scholarship and spent one year at the National Institutes of Health. In 1981 Professor Kaluza was promoted to a tenured professorship in neuropathology. He is the author of more than 110 articles published in medical periodicals and coauthor of many chapters in medical handbooks. (shrink)

Topology change is discussed as a barrier penetration process and illustrated by explicit calculations in Witten's Kaluza-Klein bubble geometry. Initial values are given for other bubble geometries, including ones with negative total mass.

We relate personal encounters of three kinds with geometrical approaches in the development of a relativistic quantum field theory of the fundamental interactions—including interactions with Nathan Rosen. We characterize the geometrical structures involved and discuss the more recent attempts to develop a unified theory based on a Klein-Kaluza contraction of the eightfold extended supergravity.

It has been shown that the orbits of motion for a wide class of non-relativistic Hamiltonian systems can be described as geodesic flows on a manifold and an associated dual by means of a conformal map. This method can be applied to a four dimensional manifold of orbits in spacetime associated with a relativistic system. We show that a relativistic Hamiltonian which generates Einstein geodesics, with the addition of a world scalar field, can be put into correspondence in this way (...) with another Hamiltonian with conformally modified metric. Such a construction could account for part of the requirements of Bekenstein for achieving the MOND theory of Milgrom in the post-Newtonian limit. The constraints on the MOND theory imposed by the galactic rotation curves, through this correspondence, would then imply constraints on the structure of the world scalar field. We then use the fact that a Hamiltonian with vector gauge fields results, through such a conformal map, in a Kaluza-Klein type theory, and indicate how the TeVeS structure of Bekenstein and Saunders can be put into this framework. We exhibit a class of infinitesimal gauge transformations on the gauge fields ${\mathcal{U}}_{\mu}(x)$ which preserve the Bekenstein-Sanders condition ${\mathcal{U}}_{\mu}{\mathcal{U}}^{\mu}=-1$ . The underlying quantum structure giving rise to these gauge fields is a Hilbert bundle, and the gauge transformations induce a non-commutative behavior to the fields, i.e. they become of Yang-Mills type. Working in the infinitesimal gauge neighborhood of the initial Abelian theory we show that in the Abelian limit the Yang-Mills field equations provide residual nonlinear terms which may avoid the caustic singularity found by Contaldi et al.

In the presented essay, I would like to focus on the relationship between force and power. The idea that power, without resorting to forceful, even violent solutions, is less problematic, is both deceitful and dangerous. Once accepted, it can cause an oversight of violence‐free but possibly harmful forms of power. My focus in the article will be on the two reinterpretations of Master‐Slave dialectics, as presented by Alexandre Kojève and Albert Camus. This will be presented with reference to the position (...) of Hannah Arendt and her remarks on power and force. In conclusion, I will be abstemious: my goal is rather to diagnose and bind the existentialist judgement with the contemporary situation and suggest that thinking outside the force‐power relationship may be continuously fruitful and an important part of reflection on the nature of political power.

We unify three approaches within the vast body of gauge-theory research that have independently developed distinct representations of a geometrical surface-like structure underlying the vector-potential. The three approaches that we unify are: those who use the compactified dimensions of Kaluza–Klein theory, those who use Grassmannian models models) to represent gauge fields, and those who use a hidden spatial metric to replace the gauge fields. In this paper we identify a correspondence between the geometrical representations of the three schools. Each school (...) was mostly independently developed, does not compete with other schools, and attempts to isolate the gauge-invariant geometrical surface-like structures that are responsible for the resulting physics. By providing a mapping between geometrical representations, we hope physicists can now isolate representation-dependent physics from gauge-invariant physical results and share results between each school. We provide visual examples of the geometrical relationships between each school for \\) electric and magnetic fields. We highlight a first new result: in all three representations a static electric field has a hidden gauge-invariant time dependent surface that is underlying the vector potential. (shrink)

The host of SUSY(supersymmetry) based string theories is considered. Superstrings are comprehended as possible candidates on Quantum Gravity basic objects. It is argued that superstring theories constitute mainly mathematical progress and can reconcile general relativity with quantum field theory at best. Yet they cannot provide the genuine synthesis. Superstring unification of all the four forces at hand is a formal one . It is contended that genesis and proliferation of superstrings can better be described not by philosophy of science models (...) but in terms of modern sociology of science. The formal character of gravity and quantum fields fusion and the lack of experimental verification make the transition to superstring theories ad hoc in Lakatosian standards. Possible way of explanation is proposed based on social interests conception of Andrew Pickering. -/- Key words: superstrings, unification, Kaluza-Klein, sociology of science . (shrink)

It is shown in the present paper that the transformation relating a parallel transported vector in a Weyl space to the original one is the product of a multiplicative gauge transformation and a proper orthochronous Lorentz transformation. Such a Lorentz transformation admits a spinor representation, which is obtained and used to deduce the transportation properties of a Weyl spinor, which are then expressed in terms of a composite gauge group defined as the product of a multiplicative gauge group and the (...) spinor group. These properties render a spinor amenable to its treatment as a particle coupled to a multidimensional gauge field in the framework of the Kaluza–Klein formulation extended to multidimensional gauge fields. In this framework, a fiber bundle is constructed with a horizontal, base space and a vertical, gauge space, which is a Lie group manifold, termed its structure group. For the present, the base is the Minkowski spacetime and the vertical space is the composite gauge group mentioned above. The fiber bundle is equipped with a Riemannian structure, which is used to obtain the classical description of motion of a spinor. In its classical picture, a Weyl spinor is found to behave as a spinning charged particle in translational motion. The corresponding quantum description is deduced from the Klein–Gordon equation in the Riemann spaces obtained by the methods of path-integration. This equation in the present fiber bundle reduces to the equation for a Weyl spinor, which is close to but differs somewhat from the squared Dirac equation. (shrink)

Recently, Michael Redhead has argued that the grouping of particles into multiplets by grand unified gauge theories (GUT's) does not, by itself, imply an ontological reduction in the number of elementary particles. While sympathetic to Redhead's argument, in this note I argue that under certain conditions involving Kaluza-Klein theories, GUT's would provide such an ontological reduction.

The usual equivalence between the Palalini and metric (or affinity and vielbein) formulations of Einstein theory fails in two spacetime dimensions for its “Kaluza-Klein” reduced (as well as for its standard) version. Among the differences is the necessary vanishing of the cosmological constant in the first-order forms. The purely affine Eddington formulation of Einstein theory also fails here.

Das Problem einer einheitlichen Grundlage alles Bestehenden hat seit jeher eine große Rolle in der Philosophie gespielt und stets auch eine große Ausstrahlung auf die Naturwissenschaft gehabt. Exemplarisch werden verschiedene Entwürfe für eine höherdimensionale einheitliche Feldtheorie diskutiert. -/- Es wird der Frage nachgegangen, was überhaupt unter der „Einheit von Theorien“ zu verstehen ist. Dabei zeigt sich, dass sich zwischen unterschiedlichen Ebenen der „Einheit von Theorien“ unterscheiden lässt. Die „Einheit von Theorien“ kann sich beziehen auf übergreifende Begriffe (z. B. Feldbegriff), auf (...) eine formal mathematische Zusammenfassung unterschied­licher Phänomene (z. B. im Rahmen der Projektiven Einheitlichen Feldtheorie), auf einen genetischen Zusammenhang von Theorien (z. B. zwischen newtonscher und relativistischer Mechanik), auf ein einheitliches Gesetz zur Erklärung unterschiedlicher Phänomene (z. B. die Maxwelltheorie als Erklärungsgrundlage elektromagnetischer Erscheinungen), aber auch auf einen gemeinsamen Referenzbereich verschiedener Theorien (z. B. phänomenologische und statistische Thermodynamik). -/- Die Verwendung höherdimensionaler Geometrien wirft die Frage nach dem ontologischen Status höherdimensionaler Raum-Zeiten auf. Handelt es sich lediglich um mathematische Formalismen, oder kommt ihnen eine eigene Realität zu? Es zeigt sich, dass beide Interpretationskonzepte ihre Berechtigung besitzen. Spielt etwa bei der Klasse der Projektiven Einheitlichen Feldtheorien (kurz: PUFT) der höherdimensionale Raum die Rolle eines Instruments zur mathematisch eleganten Darstellung, so lassen sich bei der Klasse der Kaluza-Klein-Theorien Eigenschaften ableiten, die als Hinweis auf einen ontologisch eigenständigen Realitätsstatus gedeutet werden können. Folgt man Poppers Realitätskriterium, wonach als real zu betrachten ist, was sich durch physikalische Wirkungen nachweisen lässt, so kann etwa der Einfluss der Extradimensionen auf die Dynamik des physikalischen Geschehens in der vierdimensionalen Raum-Zeit als Hinweis auf deren Realität gedeutet werden. -/- Interessant sind die höherdimensionalen einheitlichen Feldtheorien auch unter dem Blickwinkel der Wissenschaftstheorie. Da sie recht gut dem Modell des Forschungsprogramms im Sinne von Lakatos entsprechen, stellen sie gute Musterbeispiele für theoriedynamische Betrachtungen dar. (shrink)
