Ontologie et physique quantique chez Schrödinger: un retour au continu

Erwin Schrödinger is an Austrian physicist of the XXth century who took part in the elaboration of quantum mechanics and offered some alternatives to the Copenhagen interpretation. This thesis shows the whole of his thought to shed light on the origins of his wrongly understood opinions. His ontology consists of a universal-Spirit monism combined with a strong interest in the evolution of species, which lead to a double definition of consciousness : seen as a supra-individual memory in the broadest sense and as a synonym for attention in the narrower sense. A key theme of his thought is identity, from which it follows that classical bodies have a formal identity, as for quantum bodies, which are treated in a holistic way and reduced to observables. With regard to the theory of knowledge he requires the possibility to form clear images of theoretical elements, even though they don’t reflect any objective reality, and this is one of the reasons why he confronts the Copenhagen school. He reports a set of inconsistencies within quantum theory, which are presented in this work, and remained unsolved. This allows us to conclude that it is necessary to get back over these unsolved issues.
