Parsimonia ontológica : el caso de los objetos cuánticos

In this paper I will use the conceptual change between Quantum and Classical Mechanics to support the science demarcation proposed by Richard Rorty. I will rescue some characteristics of the historical development on Quantum Mechanics until the Prnciple of Complementarity´s formulation to dissolve the di"erence between the search of the truth and practical deliberation. Then I will to criticize a representational conception of knowledge to defend a pragmatist one, such as the american philospher does. As a conesequence, I will dissolve the epistemological distinction between science and other speeches, and so, the ontological one too.
