Foredrag — On 17 June, Michael Stoeltzner (University of South Carolina) will give a talk titled “The Specter of Copenhagen Positivism: Bohr and the Logical Empiricists 1936,” in which he discusses the famous 1936 Copenhagen Congress for the Unity of Science and the debates about causality, quantum indeterminism, and Bohr’s complementarity that took place during the congress.

Abstract: While the movement of Logical Empiricism emerged from within the debates about modern logic and relativity theory, quantum theory had not been among its primary concerns until the 1930s. What prompted the Logical Empiricists eventually to address it more substantively were debates that, to their mind, took an increasingly metaphysical twist. Even physicists had interpreted the new theory as a sign of the limits of scientific knowledge or a return of spontaneity into the foundations of nature. Such tendencies had to be combatted by a suitable interpretation of Bohr’s concept of complementarity, an analysis of ‘measurement’ and ‘observable’, and an embedding of quantum indeterminism into the tradition of statistical physics. Or such was the objective set for the 1936 Copenhagen Congress for the Unity of Science that was opened in Bohr’s house. This association has often been taken to indicate that Logical Empiricists advocated a positivism in the style of Heisenberg’s writings. But such an understanding neglects the plurality of views within the movement and introduces a criterion of meaning that was disputed by most, despite its alleged promise to bar metaphysics.

Michael Stöltzner is Professor of Philosophy at the University of South Carolina. He has been a founding member of the Research Unit “Epistemology of the LHC”. Besides the philosophy of particle physics, he has worked on the philosophy and history of physics and applied mathematics; core principles of mathematical physics, among them the principle of least action; history of logical empiricism and of philosophy of science, among them Logical Empiricism; and the philosophy of applied science, in particular the role of models and ceteris paribus laws.
