Changing the Rules: A New Epistemology of Science

Abstract This chapter discusses the measurement problem in the context of modern epistemology of science, setting out an epistemological framework which will be used throughout the book. I suggest that the literature on the measurement problem typically assumes that quantum mechanics is confirmed by the empirical evidence regardless of interpretation, and I argue that this ultimately founders for reasons similar to logical positivism. I then invoke recent work in the epistemology of measurement by van Fraassen, Chang and Tal to argue that we cannot make sense of scientific epistemology without a satisfactory understanding of what is going on during the process of measurement. Finally, I propose an approach to the epistemology of science inspired by Chang’s progressive coherentism, and argue that this is the right way of thinking about epistemic situations in which our understanding of the operation of our measuring devices depends crucially on the very physics we are trying to find out about.

Soviet attitude towards Bohr reflects changes in the ideological approach to science. During the last period before Stalin's death Ždanov proclaimed the campaign against Western influence in Soviet philosophy and science. Nevertheless the physicist M. A. Markov tried to introduce complementarity as a materialistic interpretation of quantum‐mechanics in 1948. He was officially condemned. This was followed by a period (1948–54) during which heavy attacks were made against the Copenhagen school. In 1958, after a personal exchange of thoughts with Bohr, academician Fock declared complementarity and probability to be irreversible steps towards a new insight into physical reality, at the same time correcting some of Bohr's epistemological conceptions.

Gaston Bachelard (1884-1962), French philosopher, followed a period of ruptures, that is, of conceptual and methodological changes in contemporary physics. He is one of several thinkers who presented important reflections for the understanding of contemporary atomistics. This article highlights the main philosophical reflections of Gaston Bachelard about the foundations of quantum mechanics. For that, it uses important concepts of its epistemology without which its ideas become incomprehensible. Thus, this work highlights how this science breaks with traditional scientific and philosophical ideas in the first half of the 20th century by presenting a new object of knowledge, namely, the quantum corpuscles. Furthermore, in order to characterize the philosophy of bachelardian quantum physics, according to the author, the nature of atomic particles stands out, as the scientific activity of this science in the creation of new phenomena is emphasized and its rationalism applied as philosophy is emphasized best suited to the new physics. Finally, it is emphasized in this work that Bachelard's ideas are different from other interpretations of quantum mechanics.
