Introduction
I am an assistant professor in philosophy at the University of Münster working mainly in philosophy of science and metaphysics. In my Ph.D. thesis “Entanglement and Causation” (2014) I argue for the claim that even the fundamental quantum realm can be understood in causal terms, if one modestly generalizes the theory of causal Bayes nets. I am interested in scientific methodology as well as in metaphysical consequences of accepted scientific results. I pursue a modest form of metaphysics, which is informed by science and well aware of the epistemic limits of human enquiry. Where appropriate, I appreciate the assistance of formal methods in answering philosophical questions.

Article
Full-text available
The most serious candidates for common causes that fail to screen off (“interactive common causes”, ICCs) and thus violate the causal Markov condition (CMC) refer to quantum phenomena. In her seminal debate with Hausman and Woodward, Cartwright early on focussed on unfortunate non-quantum examples. Especially, Hausman and Woodward's redescriptions...
Article
Full-text available
It is widely accepted that the violation of Bell inequalities excludes local theories of the quantum realm. This paper presents a new derivation of the inequalities from non-trivial non-local theories and formulates a stronger Bell argument excluding also these non-local theories. Taking into account all possible theories, the conclusion of this st...
Chapter
Entangled states are a specific feature of quantum physics that neither have a counterpart in classical physics nor in the realm of our ordinary experiences. In this chapter we outline the debate about these particular states both historically and systematically. We delineate how the debate originated in an argument for the incompleteness of quantu...

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 q...

Chapter
Verschränkte Zustände sind einer der charakteristischen Züge der Quantenphysik, für die es weder eine Entsprechung in der klassischen Physik noch in unserer alltäglichen Erfahrungswelt gibt. In diesem Kapitel umreißen wir historisch und systematisch die Debatte um diese besonderen Zustände. Wir stellen ihren Ursprung in einem Argument von Einstein,...
Chapter
Van Inwagen proposes that besides simples only living organisms exist as composite objects. This paper suggests expanding van Inwagen’s ontology by also accepting composite objects in the case that physical bonding occurs (plus some extra conditions). Such objects are not living organisms but rather physical bodies. They include (approximately) the...

Book
Full-text available
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 Herausforde...
Book
Full-text available
This book discusses the philosophy of influential contemporary philosopher Peter van Inwagen. Looking at perennial philosophical problems from a modern point of view, Peter van Inwagen’s philosophy masterfully combines positions that have been considered irreconcilable: incompatibilism concerning free will, materialism, organicism, theism and reali...
Chapter
Contemporary debates about mechanisms in the philosophy of science raise the question about the relation between constitutive and causal relations. These discussions so far have not received Ernest Sosa’s “Varieties of Causation” (1980), which addresses similar questions from a metaphysical point of view. The present paper reconstructs and evaluate...
Chapter
Die Probleme, die wir in diesem Kapitel diskutieren, haben ihren formalen Ursprung in der Art und Weise, wie in der Quantentheorie zusammengesetzte Systeme beschrieben werden (vgl. Abschn. 3.1.2).
Article
This paper expounds that besides the well-known spatio-temporal problem there is a causal problem of entanglement: even when one neglects spatio-temporal constraints, the peculiar statistics of EPR/B experiment is inconsistent with usual principles of causal explanation as stated by the theory of causal Bayes nets. The conflict amounts to a dilemma...

Einführung und Diskussion der zentralen Begriffe und Problemstellungen der Quantentheorie für Physiker und Philosophen
Article
Full-text available
It is widely accepted that the violation of Bell inequalities excludes local theories of the quantum realm. This paper presents a stronger Bell argument which even forbids certain non-local theories. The remaining non-local theories, which can violate Bell inequalities, are characterised by the fact that at least one of the outcomes in some sense p...
Article
Full-text available
We examine possible causal structures of experiments with entangled quantum objects. Previously, these structures have been obscured (i) by assuming a misleading probabilistic analysis of quantum non locality as 'Outcome Dependence or Parameter Dependence' and (ii) by directly associating these correlations with influences. Here we try to overcome...
Article
Full-text available
Loops are abundant in native RNA structures and proliferate close to the unfolding transition. By including a statistical weight approximately l(-c) for loops of length l in the recursion relation for the partition function, we show that the heat capacity depends sensitively on the presence and value of the exponent c, even for a short explicit tRN...
