Alves, Pedro M. S.2011-05-112011-05-11http://hdl.handle.net/10451/3379In this paper I address some philosophical questions regarding the impact quantum mechanics has in the classical conceptions about reality and knowledge. I stress that onto-gnosiological realism still is an option to the issues regarding the relationship between knowledge and reality. Rejecting some radical aspects of Copenhagen interpretation of quantum formalism, I emphasize the advantages of de Broglie’s realistic and causal model. To finish with, I discuss the limits of the Cartesian concept of matter and the split between matter and mind.engRealismQuantum mechanicsGnosiologyNatural philosophyRealismoTeoria quânticaGnoseologiaFilosofia da naturezapreprint
