It continues the aims of the Springer series “The Philosophy of Science in a European Perspective” and is meant to give a new impetus to European research in the philosophy of science. The main purpose of the series is to provide a publication platform to young researchers working in Europe, who will thus be encouraged to publish in English and make their work internation- ally known and available. In addition, the series will host the EPSA conference proceedings, selected papers coming from workshops, edited volumes on specifi c issues in the philosophy of science, monographs and outstanding Ph.D. disserta- tions. There will be a special emphasis on philosophy of science originating from Europe. In all cases there will be a commitment to high standards of quality. The Editors will be assisted by an Editorial Board of renowned scholars, who will advise on the selection of manuscripts to be considered for publication.

For the universe is variegated and manifold, a fabric woven of many qualities no two of which are exactly alike. A formal metaphysical monism, with its principle that all being is in truth one , does not give an adequate account; it must be supplemented with some sort of pluralistic principle. Moritz Schlick – General Theory of Knowledge, 1918/1974, p. 333 Acknowledgements The issues raised in this book have been with me since my time as an undergraduate student at Free University Berlin. When I decided to study philosophy in 2002, my intellectual landscape was dominated by a handful of critical theorists in the tradi- tion of the Frankfurt School. My fi rst contact with contemporary academic philosophy came as a shock that impressed me so deeply that I quickly changed my enrollment from philosophy and ancient history to philosophy and cognitive science. As far as I remember, this decision was made during Holm Tetens’ lecture on “Computers, Brains, and other Machines” and one of his melancholic pleas for a naturalist theory of the mind. Holm’s uncompromising insistence on intellectual honesty left us students with the pessimistic suggestion that naturalism was a tragic truth, but a truth nonetheless. The anti-naturalists’ obsession with qualia and other supposedly irreducible entities was well motivated but unfortunately not well justifi ed. Challenged by this pessimistic naturalism, I decided that my philosophical inter- ests require more than anecdotal knowledge about the natural sciences. The cognitive science program at the University of Potsdam offered a great opportunity to learn about a large range of fascinating disciplines from excellent teachers like Johannes Haack and Reinhold Kliegl. Now focusing on debates about mind and cognition, my new subjects suggested a neat division of labor. As a student of cognitive science, I would learn about empirical problems of human memory, perception, problem solving, and so on. As a student of philosophy, I would be concerned with the remaining metaphysical problems such as consciousness, intentionality, self- knowledge, or free will. However, the problems with this division of labor soon started to appear. While I did my best to follow lectures from neurolinguistics to artifi cial intelligence, the convenient philosophical distinction between “easy” empirical problems and “hard” metaphysical problems made less and less sense. On the one hand, the “easy” empirical problems weren’t so easy after all and the reductive explanations from my Introduction to Philosophy of Mind courses nowhere to be found. On the other hand, there appeared to be a wealth of fascinating empirical research on consciousness, ix x Acknowledgements intentionality, and other entities that were claimed to fall in the philosophers’ realm of competence. Of course, I was soon introduced to a number of philosophical strat- egies of explaining this discomfort away. Models of reductive explanation in philosophy of mind were not supposed to provide a realistic account of explanations in scientifi c practice. Furthermore, the “hard problem of consciousness” did not imply that scientists have nothing to say about consciousness. Instead, one just had to separate the empirically unproblematic issues such as access consciousness or neu- ral correlates from the philosophically troubling issue of phenomenal consciousness. My discomfort about the relation between philosophy of mind and the reality of scientifi c practice might have faded without three lucky coincidences during my time as student in Berlin. First, I started to work as a student assistant for Peter Bieri who had been highly infl uential in establishing analytic philosophy of mind in German philosophy but had become disenchanted with the entire discipline. I do not know whether Peter Bieri would agree with the core claims of this book, but our discussions about Wittgenstein, Goodman, and the state of philosophy of mind were the single most important event in the formation of the thoughts of this book. The second lucky coincidence was a seminar on mereology with Olaf Müller at the same time as I was exposed to Peter Bieri’s staunch criticism of the analytic mainstream that he so successfully co-established in Germany. Olaf Müller’s broadly Putnam- inspired criticism of current developments in ontology provided me with a much- needed theoretical framework to formulate my ideas. My term paper on “mereological physicalism” was a fi rst attempt to articulate my discomfort with current philosophy of mind and to sketch a broadly pluralist alternative. The third lucky coincidence was that I started working as a student assistant for Tania Munz at the Max - Planck Institute for the History of Science . I rarely talked with history of science colleagues about philosophy of mind and I rarely talk about history of science thorough this book. Still, this book would not have been possible without a perspective on science that I do not owe to philosophers but to historians. I had learned to approach philosophy of mind by starting with sweeping metaphysical doctrines (mostly physicalism and dualism in their countless varieties) and by looking at the cognitive sciences for support. It took history of science to invert this perspective. Instead of asking
