Moral consensus theory: paradigm cases of abortion and orthothanasia in Brazil.

Bioethics is a relatively new way of thinking about relationships in medical practice. It enables reflection on ethical conflicts, and opens up management options without dictating rules. Despite this historical context, medical ethics has been sidelined in the course of the development of bioethics. Bioethical reflection does not automatically result in changes to conflict resolution in daily doctor-patient relationships. However, these reflections are important because they promote the search for a "moral consensus" that establishes new ethical rules for day-to-day medical practice. We suggest that there is no conflict between bioethics and medical ethics; rather, these areas interact to establish new standards of behaviour among physicians. The legalisation of orthothanasia in Brazil is one example of how this theory of moral consensus might operate. On the other hand, the legal battle on abortion illustrates how the law cannot change without such a moral consensus.
