Abstract
Eugenics is bringing misunderstandings linked to eugenism as socio-political movement.Eugenism is the political movement, which estimated that eugenics could ameliorate the qualities of “race”. This idea, that the gene pool of the human species could be ameliorated, is not new and is even a part of the history of our nations. It is on the United States that, between 1900 and 1930, eugenism found its first socio-political successes.Eugenism has roots in the conservative movements of the 19th century and will condemn itself by the Nazi exactions. Indeed, it is abnormal that a political movement, or even nations, would impose laws with genetical implications: this eugenism must be totally rejected. However, we must continue to favour individual and free kinds of eugenics, based on precise studies and objective information.It seems normal to human beings, in his struggle against natural forces, to use his reproductive capacities on a non-animal way: a plannified and intentional reproduction must be natural to rational human beings. Not to allow this rule consists to start from theological opinions, such as the idea that the sexual act not desiring to be procreative consists in a refusal of a divine principle.
