[Biomedical update in bioethics: a primordial ethical imperative].

In this brief article we continue our reflection about the relations that should exist between the knowledge of biomedical sciences and the development of bioethics. After stating the principle of not absolute concordance between empirical and philosophical data as well as the former data are partial truths and highly contextualized by the experiment, we propose a certain criteria that should govern the use of biomedical sciences in bioethics. These criteria are based on ability to distinguish the two areas of knowledge and, without confusing each other, achieve their integration in a new unit of knowledge. Approximating the two disciplines in this way each will be more able to accommodate the other. From contiguity to integration into a higher order unit, without that both losing their own nature. We conclude that not only this posture avoid the mistake of deducting the bioethics from experimental scientific date but also not to manipulate biomedical data based on previous philosophical positions. Furthermore we also reached a more comprehensive and real understanding of bioethics. This implies that both scientists and humanists that work in bioethics must live an ethical imperative in their research that we have described as essential. This consist in a continuously update in biomedicine for research and development the bioethics.
