Abstract

To refuse new knowledge and new technologies is at long term a lost battle: this general constatation may, without doubt, be extrapolated to genetic engineering.The influence fundamental science-applied science is always mutual. Such as is also the influence science-society. If the genetics influences the society, the society influences the genetics and the sciences of the reproduction. The goal is indeed nowadays to have a limited number of children, and to offer a life of quality with minimal sufferings. Without doubt these social “norms” have indeed also an eugenetic effect. The interaction science-society appears at each important discovery by necessary adaptations.Before to decide what is moral and immoral, correct and false in the consequences of genetical techniques, one has to better understand the proposed applications and the signification of their results. It would be necessary that the society would develop a better information or even a biological culture.To fear that human beings would destroy the natural mechanisms, to phantasm on the fact that humans would go too far, corresponds in fact to make a scandal of his intelligence, to separate human beings from the nature, it is at the limit to want to limit humans to their animal origin. In this field, such as in others, humans do not need repressive morals: the ethically responsible choice is the choice of the publicity of knowledge. This education must help him to remain honest and free, to remove false sciences and prejudices.
