Contemporary Medicine is characterized by an episteme based on complexity, promoted by the recognition of the inherent limit in science, despite impressive results in technology. This change refers to the “Complexity Theory” of Morin and Prigogine [1–2] with the end of the classical rationalism, and the beginning of a new concept, where the Person is placed at the centre of the analysis. Morin develops the concept of complex systems as a global entity: a system that is different from the simple sum of the parts that compose it, in a process of adaptation to external events.
