Abstract
The present work aims to develop, very briefly, some reflections on eugenics, as a method of social selectivity, and its relationship with liberalism in current societies. To this end, at first I presented the presence of eugenics sinc Antiquity, its intimate relationship with genetics, as well as the process of instrumentalization of science, externalized in the criticism of some epistemologists. In the second moment we seek to present the investigation regarding the ethical problems arising from research directed to biogenetics from the perspective of the German philosopher Jürgen Habermas, for whom such research may, in the very near future, begin to be regulated by a market logic, bringing with it This has profound consequences for the normative self-undestanding of the individual, whose life project becomes guided by the subjective preferences of third parties.
