This paper relates the development of bioethics and the issue of euthanasia to social control. It suggests that, contrary to appearances, developments in these areas indicate increasing government control of health care practice. Specifically, it argues that, although the emergence of bioethics may appear to indicate health care professionals engaging in self-regulation, the reality is more a case of re-regulation or a shift of regulatory control from health care professionals to governments or agents of governments. By contrast, the issue of euthanasia appears to be proceeding in a different direction in that it seems to be a dispute over de-regulation of health care practice. In reality, though, it is similar to the development of bioethics. The issue of euthanasia, especially in recent years, rests on the same type of re-regulation of health care practice--a shift from medical control to increasing control by government.
