    C. F. von Weizsäckers Philosophie des Geistes
    Acta Historica Leopoldina 63 201-210. 2014.
    The paper deals with Weizsäcker’s position within the philosophy of mind. It turns out that Weizsäcker’s ontology is based on an unorthodox conception both in the philosophy of physics and in the philosophy of mind. His quantum information theoretic reductionism is based on a subtle combination of atomism and holism, his philosophy of mind connected to this is a neutral monism, which proposes a bold intertwining of mind, matter, and space.

    Erweiterte Kognition und mentaler Externalismus
    Zeitschrift für Philosophische Forschung 64 (2): 190-215. 2010.
    Recent developments under the keywords dynamicism, embodiment and situated cognition suggest the view that cognitive systems are not confined to the neural sys‐tem but leak into the world beyond the traditional system boundaries. This is the thesis of extended cognition. Such an extension of the cognitive vehicles leads to a new kind of content externalism, known as active externalism. The essay pursues three objectives: firstly, to distinguish the theses of extended cognitive and active externa…Read more

    Active Content Externalism
    Review of Philosophy and Psychology 7 (1): 17-33. 2016.
    The aim of this paper is to scrutinize active externalism and its repercussions for externalism about mental content. I start from the claim that active externalism is a version of content externalism that follows from the extended cognition thesis as a thesis about cognitive vehicles. Various features of active content externalism are explored by comparison with the known forms of passive externalism – in particular with respect to the multiple realizability of the relevant external content-det…Read more

    Gegenstand dieses Beitrags ist eine Auseinandersetzung mit der Wissenschaftlichkeit der Medizin. Den Leitfaden der Analyse bildet dabei ein jüngerer Ansatz in der analytischen Wissenschaftstheorie, wonach Systematizität als zentrales Kriterium von Wissenschaft anzusehen ist (Hoyningen-Huene 2013). Ich werde im Detail zeigen, dass die Medizin dieses mehrdimensionale Kriterium insgesamt erfüllt, dass aus der Wissenschaftlichkeit der Medizin aber gleichwohl normative Konsequenzen folgen, die beispi…Read more

    Der Aufsatz lotet den zeitgenössischen Reduktionismus aus. Im ersten Teil wird in zentrale Stationen der wissenschaftstheoretischen Debatte um Theorien-Reduktion eingeleitet, wobei das Schaffner-Hooker-Modell und die Bedeutung von Näherungsbegriffen hervorgehoben werden. Der zweite Teil behandelt die multiple Realisierbarkeit als eines der nach wie vor zentralen anti-reduktionistischen Argumente. Die Analyse soll zeigen, dass es sich hierbei nicht um ein einheitliches Phänomen handelt, sondern d…Read more

    Im ersten Abschnitt illustrierte ich die These der erweiterten Kognition und diskutiere einige mögliche Missverständnisse. Im zweiten Abschnitt werde ich vier Domänen kognitiver Erweiterung auseinanderhalten, nämlich eine Erweiterung in die körperliche, physikalische, 'informatorische' und soziale Umgebung betreffend. Um die These der erweiterten Kognition vor dem Einwand der kognitiven Inflation zu schützen, muss man für jeden dieser Bereiche (und gegebenenfalls noch spezieller) spezifische Bed…Read more

    The “Multirealization” of Multiple Realizability
    In A. Hieke & H. Leitgeb (eds.), Reduction, Abstraction, Analysis, Ontos. pp. 79. 2009.
    Multiple Realizability (MR) must still be regarded as one of the principal arguments against type reductionist accounts of higher-order properties and their special laws. Against this I argue that there is no unique MR but rather a multitude of MR categories. In a slogan: MR is itself “multi-realized”. If this is true then we cannot expect one unique reductionist strategy against MR as an anti-reductionist argument. The main task is rather to develop a taxonomy of the wide variety of MR cases an…Read more

    Handedness, self-models and embodied cognitive content
    Phenomenology and the Cognitive Sciences 7 (4). 2008.
    The paper presents and discusses the “which-is-which content of handedness,” the meaning of left as left and right as right, as a possible candidate for the idea of a genuine embodied cognitive content. After showing that the Ozma barrier, the non-transferability of the meaning of left and right, provides a kind of proof of the non-descriptive, indexical nature of the which-is-which content of handedness, arguments are presented which suggest that the classical representationalist account of cog…Read more

    Must Structural Realism Cover the Special Sciences?
    In Vassilios Karakostas & Dennis Dieks (eds.), Epsa11 Perspectives and Foundational Problems in Philosophy of Science, Springer. pp. 383--390. 2013.
    Structural Realism (SR) is typically rated as a moderate realist doctrine about the ultimate entities of nature described by fundamental physics. Whether it must be extended to the higher-level special sciences is not so clear. In this short paper I argue that there is no need to ‘structuralize’ the special sciences. By mounting concrete examples I show that structural descriptions and structural laws certainly play a role in the special sciences, but that they don’t play any exclusive role nor …Read more

    Symmetrien, Strukturen, Realismus
    In Michael Esfeld (ed.), Philosophie der Physik, Suhrkamp. pp. 368-389. 2012.
    In der modernen Physik spielen Symmetrien eine herausragende Rolle zur Identifikation und Klassifizierung der fundamentalen Theorien und Entitäten. Symmetrien dienen der Darstellung invarianter Strukturen, das geeignete mathematische Werkzeug hierfür ist die Gruppentheorie. Eine Struktur lässt sich als eine Menge von Relationen verstehen, die einer Menge von Objekten aufgeprägt sind. Strukturell charakterisierte Objekte sind daher wesentlich über ihre relationalen Eigenschaften charakterisiert. …Read more

    Is structural underdetermination possible?
    Synthese 180 (2). 2011.
    Structural realism is sometimes said to undermine the theory underdetermination (TUD) argument against realism, since, in usual TUD scenarios, the supposed underdetermination concerns the object-like theoretical content but not the structural content. The paper explores the possibility of structural TUD by considering some special cases from modern physics, but also questions the validity of the TUD argument itself. The upshot is that cases of structural TUD cannot be excluded, but that TUD is p…Read more

    Holism and structuralism in U(1) gauge theory
    Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 35 (4): 643-670. 2004.
    After decades of neglect philosophers of physics have discovered gauge theories--arguably the paradigm of modern field physics--as a genuine topic for foundational and philosophical research. Incidentally, in the last couple of years interest from the philosophy of physics in structural realism--in the eyes of its proponents the best suited realist position towards modern physics--has also raised. This paper tries to connect both topics and aims to show that structural realism gains further cred…Read more

    Why quantum theory is possibly wrong
    Foundations of Physics 40 (9-10): 1429-1438. 2010.
    Quantum theory is a tremendously successful physical theory, but nevertheless suffers from two serious problems: the measurement problem and the problem of interpretational underdetermination. The latter, however, is largely overlooked as a genuine problem of its own. Both problems concern the doctrine of realism, but pull, quite curiously, into opposite directions. The measurement problem can be captured such that due to scientific realism about quantum theory common sense anti-realism follows,…Read more

    Curve it, gauge it, or leave it? Practical underdetermination in gravitational theories
    with Tim Oliver Eynck
    Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 34 (2): 277-303. 2001.
    Four empirically equivalent versions of general relativity, namely standard GR, Lorentz-invariant gravitational theory,and the gravitational gauge theories of the Lorentz and translation groups, are investigated in the form of a case study for theory underdetermination. The various ontological indeterminacies (both underdetermination and inscrutability of reference) inherent in gravitational theories are analyzed in a detailed comparative study. The concept of practical underdetermination is pro…Read more

    The paper is a kind of opinionated review paper on current issues in the debate about Structural Realism, roughly the view that we should be committed in the structural rather than object-like content of our best current scientific theories. The major thesis in the first part of the paper is that Structural Realism has to take structurally derived intrinsic properties into account, while in the second part key elements of aligning Structural Realism with a Humean framework are outlined.

    The principles of gauging
    Philosophy of Science 68 (3). 2001.
    The aim of this paper is twofold: First, to present an examination of the principles underlying gauge field theories. I shall argue that there are two principles directly connected to the two well-known theorems of Emmy Noether concerning global and local symmetries of the free matter-field Lagrangian, in the following referred to as "conservation principle" and "gauge principle". Since both these express nothing but certain symmetry features of the free field theory, they are not sufficient to …Read more

    Does the Higgs mechanism exist?
    International Studies in the Philosophy of Science 22 (2): 119-133. 2008.
    This paper explores the argument structure of the concept of spontaneous symmetry breaking in the electroweak gauge theory of the Standard Model: the so-called Higgs mechanism. As commonly understood, the Higgs argument is designed to introduce the masses of the gauge bosons by a spontaneous breaking of the gauge symmetry of an additional field, the Higgs field. The technical derivation of the Higgs mechanism, however, consists in a mere reshuffling of degrees of freedom by transforming the Higg…Read more

    The paper deals with an attempt to present an “abductive-transcendental” argument in favour of a particular version of structural realism (SR), dubbed Intermediate SR. In the first part of the paper the general structure of transcendental arguments is scrutinized with a close view on Kant’s original version and the prospect of their abductive variation. Then the role of symmetries in modern physics, especially symmetries without real instantiations and in particular gauge symmetries is discussed…Read more

    The Just-So Higgs Story: A Response to Adrian Wüthrich (review)
    Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 43 (2): 289-294. 2012.
    I give a response to Adrian Wüthrich’s critical review of my analysis of the Higgs mechanism, in which I try to clarify some possible misunderstandings. I concede that, as Wüthrich points out, many physicists see the Higgs mechanism as the roll-over from a symmetrical potential in the initial Lagrangian to a symmetry-breaking potential, while my former analysis had basically focused on the gauge-invariant transformation of the initial Lagrangian into the intended form. My main contention, howeve…Read more

    In 1768 Immanuel Kant presented an argument showing the necessity of absolute space, i.e. substantivalism in contrast to relationalism, based on the property of handedness. While there is large consensus about the fallacy of Kant’s argument, a more recent debate exists – mainly stimulated by John Earman – about the status of the Kantian argument in view of modern physics and its fundamentally built-in parity violation, which leads to a preferred handedness. According to Earman the relationalist …Read more
