Abstract
The concept of paradigm postulated by Thomas Kuhn got an important focus within the historical framework of the scientific thinking. This article presents the Martinez proposal which points out on a New Rationality in the context of building a society based on plurality of knowledge. In order to understand this notion, the evolution of the term is involved by emphasizing the understanding of the scientific exercise in the course of history until today, a limit we are trying to surpass in order to base a new version for science-making in 21st Century.
