This paper aims to promote a dialogue with the Edgar Morin's intellectual autobiography, with the three greatest relevant subjects in his work "My demons": the epistemology, the ethics and the politics; and to enhance the importance of the complex thought in the process of producing health. The continuous investigating attitude makes Morin reflect on the provisionment of the "truths" and "conclusions". Mainly that the knowledge is never total, but multidimensional. The knowledge is proposed to be constructed which re-links, which is unaccomplished and unaccomplishable. It works with the concept of auto-ethics, the urgency of "constitution" of a humanitarian identity, a planetary conscience, the native land idea. In the politics it designates the necessity of a conscience of resistance among men, in all the times and areas, the mental, ideological, cultural and historical forces that can rouse errors and thus it strengthens the belief in the imperious necessity to rethink the politics. The logic of the complex thought of Morin has illuminated many of the arguments in the health field, since in that the phenomena that involve the health and illness process presents multiple dimensions, what makes us reflect on the complexity of the concept of health necessities.
