Etica ed eugenetica

Abstract

Recent developments in molecular biology and genetic engineering open the possibility of rethinking the meaning of an eugenic project in contemporary society. Whereas the old eugenic movement aimed at an “improvement of the race” and explicitly adopted coercitive means, eugenetics in a liberal society would be the result of the free and equal access of the public to the genetic technologies available. Buchanan, Brock, Daniels and Wikler suggest in a recent book that access to genetic therapy and enhancement can be permitted without generatine any discrimination, provided that it is regulated by rules of fairness that guarantee the equality of opportunities. Things are not so simple, anyway, because a normative model of a “perfectly healthy” individual will impose itself in the social perception, and equality of access does not protect against the discrimination of those who depart from such “perfectionist” model. A different approach is also suggested by Habermas in a recent book, where he maintains that the self-normative image of man as free and equal needs to be protected leaving the genome untouched.
