espanolThe present study suggest that evil of modern man is represented by a particular epistemology, which was set forth by german philosopher Immanuel Kant; to support this approach, the analysis start at Kant’s Copernican turn metaphor and emphatizes the importance of the contributions made by this philosopher. From that point it will be developed a second thesis: that the sciences, are a kind of expert and authorized knowledge to enunciate the truths about madness in the West, pointing out that such knowledge is based on the foundations of Kantian epistemology. This last approach involves a reflection on ethical positions and policies about disciplines such as psychology and psychiatry, and is related to their practices of social normalization, in this order of ideas the role of the technique and the role of the psi scientist in the contemporary world are critically analyzed. espanolEl presente trabajo plantea que la maldad del hombre moderno, es representada por una epistemologia particular, pensada y expuesta por el filosofo aleman Immanuel Kant; para sustentar tal planteamiento, se parte del analisis de la metafora el giro copernicano con la cual, se resalta la importancia de los aportes hechos por este pensador. A partir de alli se desarrolla una segunda tesis, que lleva a considerar a las ciencias psi como saberes autorizados y expertos para enunciar las verdades sobre la locura en occidente, senalando que estas, se cimentan sobre las bases de una epistemologia kantiana. Este ultimo planteamiento conlleva a una reflexion sobre las posturas eticas y politicas de disciplinas como la psicologia y la psiquiatria, relacionadas con sus practicas de normalizacion social, por lo que se analiza criticamente la funcion de la tecnica y el rol del cientifico psi en el mundo contemporaneo.
