Abstract

Bioethics has been in existence now for more than twenty years. Much has changed, however, since Van Rensselaer Potter2 first used the term bioethics in 1971. For Potter, bioethics was an applied science with its roots in the biological sciences and its orientation towards the betterment of human life. Today the concept is used in a different context. It has become the name given to the ethical research that has become necessary in light of the new possibilities created by revolutionary developments in medical science. Generally speaking, bioethics is concerned with the beginning and the end of life. In a certain sense, however, this is merely a de facto definition which does not possess a great deal of internal logical consistency.If we attempt to reconstruct the incredibly rapid evolution of bioethics we quickly realize how the times were truly ripe for this new discipline to begin to mature. In a very short space of time bioethics was taken seriously in just about every University and medical centre the world over. There is no part of the world which has not organised a colloquium or developed a study programme or created a Centre for Biomedical Ethics. Yet this advance is hardly surprising if we consider the fact that there have been revolutionary developments in themedical world in the 1960’s which have made it necessary to engage in serious ethical reflection on the borderline questions of human life.From the start, bioethicists have concerned themselves primarily with ethical problems related to reproductive technology such as in vitro fertilization, medically assisted fertilization with donor gametes, pregnancy termination, and the status of the embryo. More recently, however, questions concerning the end of life have entered the bioethicist’s field of interest, e.g. ethical questions related to euthanasia and the problems surrounding the artificial nutrition and hydration of persistently vegetative patients. In the meantime, of course, bioethics has broadened its field of interest beyond questions related to the beginning and end of life. Serious ethical and juridical reflection has resulted from the problems surrounding organ transplantation, transplantation of brain tissue, and the problem of AIDS.With the many recent developments in genetics, the first applications of gene therapy, and the world-wide human genome research project bioethics is assured an exciting future. It is clear that the issues which grab the bioethicist’s attention are rather disparate. Moreover, we are now beginning to realize that a whole gamut of specific questions cannot be addressed unless the broader context of the ethics of health care in general is taken into account. Such a realization has led to something of a new movement within the bioethical sphere which is interested in widening the notion of ‘medical ethics’ or ‘ethics of health’.The purpose of this article is to help familiarize the reader with the world of bioethics. Such a task is both simple and complex; bioethics has become a house with many rooms, a house, furthermore, which is being constantly renovated and rebuilt. By way of introduction, we shall take an investigative and evaluative stroll through the broad landscape bioethics has traced in the first twenty years of its existence
