The course aims, on the one hand, to offer an introduction to the most important notions and debates in the philosophy of science, as well as to its fundamental authors. On the other hand, its objective will be to approach scientific research from a social, political and economic perspective, making it one more social activity. Thus, this subject is oriented to offer a realistic image of scientific research and of the perplexities and problems posed by the scientific image of reality. The student will end up knowing basic notions of epistemology and the ideological, sociological and political foundations of the scientific exercise. Finally, past and present initiatives for the organization of the scientific community for social and self-reflexive/critical purposes will be presented.
