[Becoming a scientist: the perspective of Bruno Latour].

The purpose of this article is to raise some points for an understanding of contemporary French philosopher Bruno Latour's perspective on the professionalization process for scientists. We review part of the sociological literature that has attempted to conceptually differentiate occupations from professions. We thus intend to establish a number of comparative parameters for such concepts. The field of knowledge and its role in the stages of the professionalization process assume an important place in this reflection.
