[The bioethics as a new paradigm]

The word "bioethics" is a key to understand the nature and the origins of this new discipline. Made up of bios and ethiké (life and ethics), that it conjugates biology and moral in paradigmatic synthesis of science and it makes aware, facts and values, to be and duty to be. If there is "two cultures" that seem unable to speak one to the other one, science and humanities, and if this is part of the reason for which the future is shown so uncertain, then we should spread a "bridge toward the future" building the discipline of the bioethics like a bridge among the two cultures. To what bios and to what ethos does the the bioethics refer? By definition, it is biology or biomedicine and of ethics applied to the human behavior. The bioethics, bridge toward the future and among the two cultures, he or she responds to the challenge of the crisis bioethics of the technological era, crisis at the same time vital and normative in whose warp stands out the ecological catastrophe, the new biology and the medicalization of the life.
