Abstract
This paper is based on three assumptions. The first is that bioethics is important. I define bioethics as: A study of the ethical questions posed by the application of man's knowledge to his own body, and or the ethical questions posed by our relationship to other organisms. In other words, bioethics considers some aspects of the question of man's place in nature.
