La aparición de la bioética y el porqué de la misma

In the first part, the author searches, randomly taking some historical events of the first half of last century, some choose both events in political, social and scientific to be showing that the West was slowly changing especially with the maintenance of a conflict continuum, while also allowed to express the desire to search and research in the scientific field. But all that has a great breaking point from the decade of the sixties thereafter... things are different. Is allowed to speak the facts that are considered significant during those first five decades of the last century. In the second part some events that can be considered as precursors to the emergence of bioethics in the West, from the hand of Van Rensselaer Potter, to the end, try to answer the question of why bioethics addresses: for a bridge to ensure the survival of LIFE on this planet is needed.
