21Neurophenomenal Structuralism. A Philosophical Agenda for a Structuralist Neuroscience of ConsciousnessNeuroscience of Consciousness 2022 (1). 2022.The program of “neurophenomenal structuralism” is presented as an agenda for a genuine structuralist neuroscience of consciousness that seeks to understand specific phenomenal experiences as strictly relational affairs. The paper covers a broad range of topics. It starts from considerations about neural change detection and relational coding that motivate a solution of the Newman problem of the brain in terms of spatiotemporal relations. Next, phenomenal quality spaces and their Q-structures are…Read more

63The State Space of Artificial IntelligenceMinds and Machines 30 (3): 325-347. 2020.The goal of the paper is to develop and propose a general model of the state space of AI. Given the breathtaking progress in AI research and technologies in recent years, such conceptual work is of substantial theoretical interest. The present AI hype is mainly driven by the triumph of deep learning neural networks. As the distinguishing feature of such networks is the ability to self-learn, self-learning is identified as one important dimension of the AI state space. Another dimension is recogn…Read more

1492Medizin als Wissenschaft - eine wissenschaftstheoretische AnalyseIn Daniela Ringkamp & Héctor Wittwer (eds.), Was ist Medizin? Der Begriff der Medizin und seine ethischen Implikationen, Alber. 2018.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

49Socially Extended Cognition and Shared IntentionalityFrontiers in Psychology 9 351766. 2018.The paper looks at the intersection of extended cognition and social cognition. The central claim is that the mechanisms of shared intentionality can equally be considered as coupling mechanisms of cognitive extension into the social domain. This claim will be demonstrated by investigating a detailed example of cooperative action, and it will be argued that such cases imply that socially extended cognition is not only about cognitive vehicles, but that content must additionally to be taken into …Read more

38Philosophy of Quantum Physics (edited book)Springer International. 2018.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 …Read more

34Newton, Goethe and the Alleged Underdetermination of Ray OpticsJournal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 49 (4): 525-532. 2018.Did Goethe devise an empirically viable theory of classical ray optics? Or can we at least make use of his ideas to propose one? And if so, does this confront us with an intriguing case of theory underdetermination? In this paper, which is mainly a comment on the recent work of Olaf Müller, I shall address these three questions and argue for ‘no, yes, no’. This is in contrast to Müller, who has recently launched a vivid defense of Goethe-style ray optics :569–573, 2015b; Z Philos Forsch 69:588–5…Read more

57Structures, dynamics and mechanisms in neuroscience: an integrative accountSynthese 195 (12): 5141-5158. 2018.Proponents of mechanistic explanations have recently proclaimed that all explanations in the neurosciences appeal to mechanisms. The purpose of the paper is to critically assess this statement and to develop an integrative account that connects a large range of both mechanistic and dynamical explanations. I develop and defend four theses about the relationship between dynamical and mechanistic explanations: that dynamical explanations are structurally grounded, that they are multiply realizable,…Read more

63The paper has three parts. In the first part ExtOSR, an extended version of Ontic Structural Realism, will be introduced. ExtOSR considers structural properties as ontological primitives, where structural properties are understood as comprising both relational and structurally derived intrinsic properties or structure invariants. It is argued that ExtOSR is best suited to accommodate gauge symmetry invariants and zero value properties. In the second part, ExtOSR will be given a Humean shape by c…Read more

302Is 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

590Symmetrien, Strukturen, RealismusIn 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

140The principles of gaugingPhilosophy 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

48Metaphysik im “Handumdrehen” – Kant und Earman, Parität und moderne RaumauffassungPhilosophia Naturalis 42 (1): 49-76. 2005.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

201Humean perspectives on structural realismIn F. Stadler (ed.), The Present Situation in the Philosophy of Science, Springer. pp. 381--397. 2009.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.

2539Active Content ExternalismReview 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
