La pluralité des interprétations d'une théorie scientifique : le cas de la mécanique quantique

Abstract : Some scientific theories admit several interpretations, i. e. they are compatible with several images of the world. Here, I study the case of contemporary quantum mechanics as an example of a theory which admits varied interpretations. Among the most famous interpretations of quantum mechanics are the orthodox Copenhagen interpretation, Bohmian Mechanics, and Everett's many-worlds interpretation. There is presently no consensus vis-à-vis the right interpretation of quantum mechanics, whether it is among physicists or among philosophers. This thesis studies the stakes of such a plurality of interpretations, through several methodological viewpoints. The first one proposes a formal analysis of what quantum interpretations are and in which sense they are interpretations of the same theory, i. e. remain empirically equivalent. In a second part, I study the roles played by quantum interpretations in scientific practice. I study the unity in quantum research, in spite of the diversity of the quantum interpretations which are used. I propose a concept of unity based on the reuse of scientific works, when different interpretations are adopted. In a third part, I look at the normative aspects of the plurality of interpretations. I investigate under which conditions a plurality of interpretations can be good for research work and for epistemic progress. To this end, I propose a game-theoretic model.
