The origins and evolution of bioethics: some personal reflections

Bioethics was officially baptized in 1972, but its birth took place a decade or so before that date. Since its birth, what is known today as bioethics has undergone a complex conceptual metamorphosis. This essay loosely divides that metamorphosis into three stages: an educational, an ethical, and a global stage. In the educational era, bioethics focused on a perceived "dehumanization" of medicine by the rising power of science and technology. Remedies were sought by introducing humanities, ethics, and human "values" into the medical curriculum. Ethics was one among the humanistic disciplines, but not the dominant one. In the second era, ethics assumed a dominant role as ever more complex dilemmas emerged from the rapid pace of biological research. As such dilemmas were applied to medical practice, the need for a more rigorous and more formal analysis of their moral status was clear. Philosophically-trained ethicists had an obvious role. They began to teach, write, and profoundly influence medical education and practice. In the third -- and present -- period, the breadth of problems has become so broad that ethicists must, themselves, draw on disciplines well beyond their expertise -- e.g., law, religion, anthropology, economics, political science, psychology, and the like. The era of bioethics as a global enterprise is upon us. The original hope for humanizing medicine has not been overtly successful; however, much has been accomplished of value to patients, the profession, and society. Medical morality has been transformed into a formal, systematic study of a whole range of issues of the greatest significance to humanity. Now the major challenge is one of identity, or inter-relationships and connections between the theoretical and the practical. Bioethics has outgrown its beginnings.
