Abstract : Between ethics and epistemology, the thesis aims to clarify the contribution of experimental sciences to moral philosophy. Moral systems are today subject to two pressures, one due to the development of cognitive sciences and the other to the globalization of human interactions. They have to respond to these pressures without harming their role in regulating local social groups. Experimental philosophers have sought to use cognitive sciences to discuss philosophical questions. The thesis is based on this XPhi experience, the results of which, neither insignificant nor decisive, have raised many reservations from moral philosophers. The thesis has three chapters describing the moral and experimental domains, then a central chapter with five case studies using experimental results in philosophical debates. The key role of operationalization in these debates is then analyzed: how to know that an experience is relevant to study a psychological entity? The reluctance of moral philosophers and the responses of scientists are finally taken up. From this work, the thesis draws methodological lessons and defends three proposals. 1- The operationalization of entities is a nodal point of experimental psychology. 2- The theory of evolution suggests fruitful paths, distinguishing three time scales, speciation, social groups and individuation. 3- Little can be said of moral philosophy in general with regard to experimentation, but useful analyzes can be offered from four perspectives: descriptive, prescriptive, meta-ethical and applied ethics.
