Por qué investigar en bioética? / Why should we research in bioethics?

This article reviews the conceptual evolution of bioethics, conditioned by cultural changes. The discipline could be strengthened with new analytical methodologies and with an empirical approach. The dangers of a purely descriptive bioethics, solely linked to practical experience are also discussed. This may cause the loss of the regulatory frame, that allows bioethics to enrich medical practice from a humane and moral viewpoint. Therefore, there is a need to find the balance between the theoretical analysis and an empirical approach, to face the growing complexity of contemporary ethical problems.
