Causalità e realtà nel dibattito sulla meccanica quantistica degli anni '30 del Novecento : una possibile ricostruzione

A possible reconstruction. As with any scientific revolution, quantum mechanics entailed a profound revision of our fundamental epistemological concepts and also of our worldview as a whole. This was the case for the concepts of causality and reality. Around these concepts, there arose in the third decade of the last century a heated debate in which almost all the scientists and philosophers of the time took part and which in a certain sense is still going on today. The Author provides a reconstruction of the various different positions, from the “conservative” attempt to defend determinism to the most radical stochastic positions, and singles out in Ernst Cassirer’s solution the most convincing approach.
