According to the received view Feynman diagrams are a bookkeeping device in complex perturbative calculations. Thus, they do not provide a representation or model of the underlying physical process. This view is in apparent tension with scientific practice in high energy physics, which analyses its data in terms of “channels”. For example the Higgs discovery was based on the observation of the decay H → γγ – a process which can be easily represented by the corresponding Feynman diagrams. I take (...) issue with this tension and show that on closer analysis the story of the Higgs discovery should be told differently. (shrink)

Die Autorinnen und Autoren präsentieren in diesem Buch Argumente, die die Unmöglichkeit des Reduktionismus aus philosophischer, naturwissenschaftlicher bzw. mathematisch-logischer Perspektive zu begründen suchen. Der Reduktionismus behauptet, dass Eigenschaften auch von komplexen Systemen vollständig auf ihre Bestandteile zurückgeführt werden können. Diese Position ist einflussreich, aber umstritten. Im Jahr 2019 hat der Kurt Gödel Freundeskreis einen Essaywettbewerb veranstaltet, um schlagende Argumente gegen den Reduktionismus zu finden. Unter den internationalen Teilnehmern waren neben weltweit führenden Forschern auch Wissenschaftler, die noch am Beginn ihrer Kariere (...) stehen. Dieser Band versammelt die Beiträge der Preisträger und weitere ausgewählte Aufsätze. Aus dem Inhalt: · Kausalität als antireduktionistisches Hausmittel – Martin Breul · Reduktionismus im Diskurs – Hanna Hueske · Monads, Types, and Branching Time – Kurt Gödel’s approach towards a theory of the soul – Tim Lethen · The limits of reductionism: thought, life, and reality – Jesse M. Mulder · True or Rational? A Problem for a Mind-Body Reductionist – Michał Pawłowski · Why reductionism does not work – George F. R.

Interference of more and more massive objects provides a spectacular confirmation of quantum theory. It is usually regarded as support for “wave–particle duality” and in an extension of this duality even as support for “complementarity”. We first give an outline of the historical development of these notions. Already here it becomes evident that they are hard to define rigorously, i.e. have mainly a heuristic function. Then we discuss recent interference experiments of large and complex molecules which seem to support this (...) heuristic function of “duality”. However, we show that in these experiments the diffraction of a delocalized center-of-mass wave function depends on the interaction of the localized structure of the molecule with the diffraction element. Thus, the molecules display “dual features” at the same time, which contradicts the usual understanding of wave–particle duality. We conclude that the notion of “wave–particle duality” deserves no place in modern quantum physics. (shrink)

Dieses Buch liefert dem Leser eine aktuelle und fundierte Einführung in die Philosophie der Quantenphysik. Obwohl sich die Quantentheorie durch spektakuläre empirische Erfolge auszeichnet, wird bis heute kontrovers diskutiert, wie sie zu verstehen ist. In diesem Werk geben die Autoren einen Überblick über die zahlreichen philosophischen Herausforderungen: Verletzen Quantenobjekte das Prinzip der Kausalität? Sind gleichartige Teilchen ununterscheidbar und daher keine Individuen? Behalten Quantenobjekte in der zeitlichen Entwicklung ihre Identität? Wie verhält sich ein zusammengesetztes Quantensystem zu seinen Teilen? Diese Fragen werden (...) im Rahmen verschiedener Deutungsansätze der Quantentheorie diskutiert. Ein Ausblick in die Quantenfeldtheorie verschärft das Hauptproblem der Nichtlokalität. Philosophie der Quantenphysik richtet sich an Philosophen mit Interesse für Physik, macht Physiker mit den philosophischen Fragen ihres Faches vertraut und liefert Anregungen für den gymnasialen Physik-Unterricht. Das Buch schließt damit eine Lücke zwischen populären Einführungen und spezialisierten Monografien zur Philosophie der Quantenphysik. In der vorliegenden zweiten Auflage wurde das Kapitel zu Verschränkung und Nicht-Lokalität deutlich erweitert und jedes Kapitel mit Übungsaufgaben und Musterlösungen ergänzt. (shrink)

This book provides a thorough and up-to-date introduction to the philosophy of quantum physics. Although quantum theory is renowned for its spectacular empirical successes, controversial discussion about how it should be understood continue to rage today. In this volume, the authors provide an overview of its numerous philosophical challenges: Do quantum objects violate the principle of causality? Are particles of the same type indistinguishable and therefore not individual entities? Do quantum objects retain their identity over time? How does a compound (...) quantum system relate to its parts? These questions are answered here within different interpretational approaches to quantum theory. Finally, moving to Quantum Field Theory, we find that the problem of non-locality is exacerbated. Philosophy of quantum physics is aimed at philosophers with an interest in physics, while also serving to familiarize physicists with many of the essential philosophical questions of their subject.

Many research fields concerned with the processing of information contained in human faces would benefit from face stimulus sets in which specific facial characteristics are systematically varied while other important picture characteristics are kept constant. Specifically, a face database in which displayed expressions, gaze direction, and head orientation are parametrically varied in a complete factorial design would be highly useful in many research domains. Furthermore, these stimuli should be standardised in several important, technical aspects. The present article presents the freely (...) available Radboud Faces Database offering such a stimulus set, containing both Caucasian adult and children images. This face database is described both procedurally and in terms of content, and a validation study concerning its most important characteristics is presented. In the validation study, all frontal images were rated with respect to the shown facial expression, intensity of expression, clarity of expression, genuineness of expression, attractiveness, and valence. The results show very high recognition of the intended facial expressions. (shrink)

“Father” Zachary Hale Comstock is a self‐professed prophet, religious zealot, and racist, who has kept his “heir” under lock and key in the floating city of Columbia. Booker DeWitt is a washed‐up, disgraced ex‐Pinkerton agent haunted by his participation in the Wounded Knee Massacre. He enters Columbia to rescue Elizabeth in exchange for having his gambling debts settled. After much bloodshed, Booker saves Elizabeth and kills Comstock. In the past, Booker attended a baptism to assuage his guilt over Wounded Knee. (...) In some worlds he rejected the baptism, got married, had a daughter, Anna, and ended up as an indebted alcoholic ex‐Pinkerton agent. In the Comstock world, Anna is renamed Elizabeth in order to conceal her true origins. BioShock Infinite paints a metaphysical picture that treats the many‐worlds interpretation of quantum mechanics as reality. (shrink)

Diffeomorphism invariance is sometimes taken to be a criterion of background independence. This claim is commonly accompanied by a second, that the genuine physical magnitudes (the ``observables'') of background-independent theories and those of background-dependent (non-diffeomorphism-invariant) theories are essentially different in nature. I argue against both claims. Background-dependent theories can be formulated in a diffeomorphism-invariant manner. This suggests that the nature of the physical magnitudes of relevantly analogous theories (one background free, the other background dependent) is essentially the same. The temptation (...) to think otherwise stems from a misunderstanding of the meaning of spacetime coordinates in background-dependent theories. (shrink)

The article seeks to stress the importance of two main innovations in Ernesto Laclau's recent work: what his theory of populism in On Populist Reason provides in terms of theoretical innovations is , a political theory of naming, and , a political theory of the heterogeneous. Furthermore, it is asked what it means to name, as Laclau himself does, the subject of the political "the people" and to define populism as the logic of all politics. It is argued against potential (...) criticism that these rather strong claims, far from being overstretched, in fact must be understood in the light of Laclau's new ideas on political naming and the heterogeneous, since his notions of populism and "the people" are the outcome of political nomination, that is, a political wager on Laclau's part , and the name of "the people," like every political name, will always cast a shadow on the heterogeneous as that which cannot be named.

English has plural terms as well as singular terms. But our standard formal languages, e.g., the predicate calculus, feature only singular terms. How can the plural idiom be formalized?‘Changing the subject’ is by far the most common plurals strategy among both philosophers and linguists: a plural term is replaced by a singular term standing for some complex object that ‘contains’ the individuals to which the plural term alludes. For example, one might simply replace ‘A, B imply C’ with ‘{A, B} (...) implies [singular] C’. We uncover a surprising variety of ways to change the subject, of ever‐increasing complexity and ingenuity. Our question is whether any can made to work. (shrink)

_Skepticism and Cognitivism_ addresses the fundamental question of epistemology: Is knowledge possible? It approaches this query with an evaluation of the skeptical tradition in Western philosophy, analyzing thinkers who have claimed that we can know nothing. After an introductory chapter lays out the central issues, chapter 2 focuses on the classical skeptics of the Academic and Pyrrhonistic schools and then on the skepticism of David Hume. Chapters 3 through 5 are devoted to contemporary defenders of skepticism—Keith Lehrer, Arne Næss, and (...) Peter Unger. In chapter 6, author Oliver A. Johnson dons the mantle of skeptic himself and develops and adds theories to the skeptical arsenal. He closes with an examination of the relationship between skepticism and cognitivism, reaching and defending conclusions on the nature and extent of possible human knowledge. (shrink)

This article proposes a theological emphasis to the definition of προσλαμβάνω in Romans 14–15. Previous accounts have emphasised the domestic and social implication of Paul's imperative—‘welcome one another’ (Rom. 15:7a). The result has been that what Paul might have meant by God's and Christ's ‘welcome’ (Rom. 14:3 and 15:7b) has been governed by the ethical imperative. In order to investigate the ‘welcome’ of God and Christ, this article proposes a context of three important Septuagintal antecedents as yet unconsidered: 1 Samuel (...) 12, Psalm 18, and Psalm 65: In this context, God's and Christ's ‘welcome’ in Rom. 14–15 incorporates notions of justification, election, salvation, and unified worship. A theological reading of προσλαμβάνω, using these intertextual resources, therefore provides a stronger position from which to understand Paul's imperative—‘welcome one another’. (shrink)

Immanuel Kant is often considered to be the source of the contemporary idea of human dignity, but his conception of human dignity and its relation to human value and to the requirement to respect others have not been widely understood. Kant on Human Dignity offers the first in-depth study in English of this subject. Based on a comprehensive analysis of all the passages in which Kant uses the term ;dignity, as well as an analysis of the most prominent arguments for (...) a value of human beings in the Kant literature, the book carefully examines different ways of construing the relationship between dignity, value and respect for others. It takes seriously Kant s Copernican Revolution in moral philosophy: Kant argues that moral imperatives cannot be based on any values without yielding heteronomy. Instead it is imperatives of reason that determine what is valuable. The requirement to respect all human beings is one such imperative. Respect for human beings does not follow from human dignity for this would violate autonomy but is an unconditional command of reason. Following this train of thought yields a unified account of Kant s moral philosophy. (shrink)

The concept of mediation plays a central part in several positions of contemporary philosophy of technology. Especially Don Ihde and Peter-Paul Verbeek have served to establish mediation as one of the core concepts in the postphenomenologically rooted philosophical analysis of human-technology-world relations. While meditation theory provides many important conceptual and empirical contributions to our knowledge of how material artefacts shape our embodied being in the world, too little attention has arguably been given to the development of concepts that enable a (...) philosophical analysis of the symbolic aspect of technological artefacts. This paper aims to develop the notion of ‘symbolic mediation’ by drawing on inspiration from the tradition of philosophical anthropology, more specifically, the work of Ernst Cassirer and his Philosophy of Symbolic Forms (PSF). Drawing on empirical examples of human-robot interactions (HRI), I coin two types of symbolic mediation: 1) mythic mediation and 2) aesthetic mediation. (shrink)

I argue that notions of relative fundamentality need to be invoked if there is to be something substantive at stake in the debate between proponents of Harvey Brown's dynamical approach to relativity and defenders of a more traditional interpretation of spacetime. I will review some problems that stand in the way of the advocate of the dynamical approach making good on their claim that dynamical symmetries are more fundamental than spacetime symmetries.

Die Psychologie nimmt im Werk Christian Wolffs (1679-1754) eine zentrale Stellung ein. Sie begründet die Logik und die praktische Philosophie mit Naturrecht, Ethik, Politik und Ökonomik. Der vorliegende Band geht den vielfältigen Problemen nach, die sich mit Wolffs Konzeption einer rationalen und einer empirischen Psychologie einerseits, ihrer Grundlegungsfunktion innerhalb des Wolffschen Systems der Philosophie andererseits ergeben. Darüber hinaus stellt er die Psychologie Wolffs in den philosophie- und wissenschaftsgeschichtlichen Kontext von der Scholastik bis zur kritischen Philosophie Immanuel Kants.

Der Begriff der Autorität verortet sich im 20. Jahrhundert in einer komplexen Matrix zwischen zeitgeschichtlichem Problembewusstsein, »konservativem« Denken und politischer Theoriebildung. Drei Perspektiven kennzeichnen die Rede von Autorität im 20. Jahrhundert: erstens die vermeintliche Krise einer vormals fraglosen Gültigkeit, zweitens der Versuch genealogischer Rückversicherung durch Versatzstücke der Tradition und drittens die Behauptung, Autorität könne als Grundbegriff politischer Theoriebildung und insbesondere demokratischer Ordnungen dienen. Der Sammelband analysiert das Konzept der Autorität entsprechend entlang der drei Dimensionen der Krise, der Konstruktion und der (...) Konjunktur. Der Band arbeitet dabei interdisziplinär: Vereint werden historische, literaturwissenschaftliche und philosophische Ansätze. (shrink)

Anyone who's had an argument about politics with a friend may walk away wondering how this friend could possibly hold the beliefs they do. A few self-reflective people might even wonder about their own political beliefs after such an argument. This book is about the reasons that people have, and could have, for political beliefs: the evidence they might draw on, the psychological sources of their views, and the question of how we ought to form our political beliefs if we (...) want to be rational. The book's 24 chapters are divided into four larger sections, which cover: (1) the differences between political and other types of beliefs, (2) theories of political belief formation, (3) sources of our political beliefs and how we might evaluate them, and (4) contemporary phenomena-like polarization, fake news, and conspiracy theories-related to political beliefs. Along the way, the book addresses questions that will arise naturally for many readers, like: Does the news you choose to watch and your own social media leave you stuck in an "information bubble"? Are you committed to a certain ideology because of the history of your society? Are people who believe "fake news" always acting irrationally? Does democracy do a good job of figuring out what's true? Are some political beliefs good and some evil? As the book investigates these and other questions, it delves into technical, philosophical topics like epistemic normativity, the connection between belief and action, pragmatic encroachment, debunking arguments, and ideology critique. Chapter summaries and discussion questions will help students and all interested readers better grasp this new, important area on the border of politics and philosophy. (shrink)

Substantivalists believe that spacetime and its parts are fundamental constituents of reality. Relationalists deny this, claiming that spacetime enjoys only a derivative existence. I begin by describing how the Galilean symmetries of Newtonian physics tell against both Newton's brand of substantivalism and the most obvious relationalist alternative. I then review the obvious substantivalist response to the problem, which is to ditch substantival space for substantival spacetime. The resulting position has many affinities with what are arguably the most natural interpretations of (...) special and general relativity. I move on to consider and reject two recent antisubstantivalist lines of thought. The interim conclusion is that the best argument for relationalism is an appeal to Ockham's razor. However, for this to be successful there must be genuine relationalist theories that share the theoretical virtues of their substantivalist rivals but without the additional ontological commitment. The bulk of the paper is therefore an investigation of various concrete relationalist proposals. I distinguish three options for the relationalist in the face of the success of Galilean invariant physics and trace how these generalise to relativistic physics. One of the options is particularly promising but, since its basic objects end up being spacetime points, this does not help the prospects of relationalism as traditionally conceived. I end with some reflections on the fate of substantivalism in the aftermath of the Hole Argument, concluding that we have as yet to be given good reasons to abandon the natural, substantivalist interpretation of current physics.

The late Vivienne Westwood sketched a role for fashion that elevates it from the prosaic to the status of art, as something important, life-enhancing, and worthy of pursuit. Here, a philosophical treatment of Westwood’s vision of fashion that does justice to the artistic and life-enhancing value that fashion can realise is offered, using an emergent theory in contemporary analytic aesthetics. The virtue theory of art delineates the intrinsic worth of art in terms of the opportunities it provides for us to (...) exercise and cultivate virtues such as courage, self-expression, imagination, wit, or authenticity. Our engagement with art can subsequently be genuinely life-enhancing in lieu of the constitutive role the virtues play in living well. The present study takes Westwood’s claims as a jumping-off point, considering how they speak not just to her own designs but to our relationship with our clothes more broadly. Fashion is defended as a practice that performs this function in analogous ways to other genres of art and thus has clear artistic value as well as enables us to live well. Given this potential, just as Westwood claimed, there are reasons to perform the practice well because it has importance for the ways in which it can realise artistic value and aid us in living well.

Kant's Transition Project and Late Philosophy is the first study to provide a close reading of the connection between texts written by Kant during 1796 and 1798. Connecting Kant's unfinished book project, the Opus postumum, with the Metaphysics of Morals, it identifies and clarifies issues at the forefront of Kant's focus towards the end of his life. Labelled by Kant as the “Transition Project”, the Opus postumum generates debate among commentators as to why Kant describes the project as filling a (...) “gap” within his system of critical philosophy. This study argues for a pervasive transition project that can be traced through Kant's entire critical philosophy and is the key to addressing current debates in the scholarship. By showing that there is not only a Transition Project in Kant's theoretical philosophy but also a Transition Project in his practical philosophy, it reveals why an accurate assessment of Kant's critical philosophy requires a new understanding of the Opus postumum and Kant's parallel late writings on practical philosophy. Rather than seeing Kant's late thoughts on a Transition as afterthoughts, they must be seen at the centre of his critical philosophy. (shrink)

In den letzten Jahren ist der Begriff der ›Person‹ zu einem Schlüsselbegriff des philosophischen wie des gesellschaftlichen Diskurses geworden. Eine systematisch interessante und bisher vernachlässigte historische Rückversicherung in der Personendebatte bieten die Überlegungen Friedrich Heinrich Jacobis (1743–1819) und Johannes Paul Richters (1763–1825), genannt Jean Paul. Jean Paul ist um 1800 nicht nur ein erfolgreicher Autor humoristischer Romane, sondern auch ein gut informierter Beobachter der zeitgenössischen Philosophie und philosophischer Vertrauter Friedrich Heinrich Jacobis. Wie Jacobi in einer konstitutiv doppelsinnigen Bewegung Spinozas Ethik (...) und Fichtes Wissenschaftslehre als unwiderlegbare Entwürfe einer streng rationalen Immanenzphilosophie dechiffriert, um sie im Namen der ›Vernunft‹ zu überwinden, so verbindet auch Jean Pauls philosophisches und poetisches Werk die Wertschätzung der Transzendentalphilosophie unmittelbar mit einem transrationalen Widersprechen gegen die Ansprüche der neuen Systemphilosophie. Um Individualität, Zeitlichkeit und Handlungsfreiheit als Grunderfahrungen menschlichen Daseins philosophisch zureichend zu würdigen, bedarf es für Jean Paul wie für Jacobi einer grundsätzlichen Umwertung des Verhältnisses von individuellem personalem Dasein und rationaler Welt- und Selbsterklärung.

Die Simmel-Cassirer-Kontroverse behandelt den grundlegenden technikphilosophischen Gegensatz zwischen Kulturpessimismus und Kulturoptimismus. Diesen virtuellen Dialog beider Denker arbeitet Oliver Honer neu auf und entwickelt in einem aufsteigenden Reflexionsgang die Simmel'sche Rede von der »kulturellen Logik der Objekte« zum Begriff. Damit modelliert er das Verhältnis agierender Individuen zu ihren jeweiligen Möglichkeitsräumen und zeigt deren prekären Subjektstatus in diesen Räumen auf. Die dabei freigelegten Verhältnisse eröffnen angesichts technisch induzierter Eigenlogiken neue Wege einer dialektischen Kulturkritik.
