Dynamique épistémologique de la science : défense d'une gestion pragmatique des problèmes complexes
This thesis proposes an analysis of the epistemological role of complex scientific problems. Starting from the epistemological holism inherited from the philosophical positions of Pierre Duhem and Willard Van Orman Quine, and from the thesis that scientific practice is always based on a recognized theoretical and conceptual field, we develop a management model that proposes that researchers adopt a pragmatic attitude to react to complex problems. We explain in this research that these problems affect the applicability of theories and concepts that form scientific knowledge. To solve them, we must initiate research that will follow the steps of a pragmatic process to progressively assess the situation and gain a better understanding. During this period, the negative consequences of the complex problem are tolerated in order to ensure the maintenance of the scientific activities that it directly targets, or not, the achievement of a solution. The thesis defended in this study is that the management of the complex problems that it proposes is concluded by the rational elaboration, framed by pragmatic decisions and a favorable conjuncture, of an ad hoc hypothesis offering a solution to the problem. If the scientific community recognizes the epistemological value of this hypothesis, it will be integrated into the theoretical and conceptual field which will have the effect of enriching scientific knowledge and giving back to science its "normal" status.
