Abstract
The first part of this article shows that oureffective means to know and modify directly thehuman genetic make-up generates singular anddifficult situations for the application offundamental medical categories. Specifically,we demonstrate that in dealing with thesesituations, some predominant views on health,such as descriptivism or that which reduces thestate of health to not having presentdisabilities, cannot provide adequate answerseither from the point of view of medicalscience or in terms of our ordinary intuitions.The second part of the article examines thereasons for the failure of these views totackle the mentioned situations, proposessolutions to urgent problems and, finally,offers some foundations for an alternativetheoretical development, id est, for atheory of health able to satisfactorilyintegrate our genetic dimension
