Nobel Laureate in physics Wolfgang Pauli studied philosophy and the history of ideas intensively, especially in his later years, to form an accurate ontology vis-à-vis quantum theory. Pauli's close contacts with the Swiss psychiatrist C.G. Jung gave him special qualifications for also understanding the basic problems of empirical knowledge. After Pauli's sudden death in 1958, this work was maintained mainly in his posthumously published correspondence, which so far extends only to 1939. Because Pauli's view differs essentially from the direction physics (...) research took after the deaths of the founding fathers of quantum theory, this article attempts to describe the main features in Pauli's revolutionary thought, which is based on nature's “epistemological lesson” as revealed by Pauli's atomic research. Pauli's conclusions have important implications for various issues in Western culture, not least with the limits of science and the relation of science to religion. (shrink)

Wolfgang Pauli is known as one of the most famous physicists of the 20th century. Next to an intensive treatment of physics, his impressive correspondence with fellow physicists also demonstrates a vivid interest in psychology and biology. Reflections on the mind-brain problem and on topics such as causality and evolutionary theory are readily present. In this paper, some central passages in this correspondence are discussed and linked to more current debates in philosophy of science and philosophy of biology. It is (...) shown how Pauli speculatively explored how evolutionary theory can find inspiration in quantum theory and in its related concept of observer-dependency. Contra Kalervo Laurikainen's interpretation, it is argued that Pauli's criticism remains true to a naturalistic view on science and biology. (shrink)
