Abstract
According to many scientists and philosophers, recent biotechnological discoveries and advances lead inescapably to the new, fundamental question: why consider the existing nature of man as untouchable, as sacred? Whereas the general public feels fear and outrage at the very thought of the creation of 'monsters', leading bioethicists find all this talk about the sacredness of human nature unacceptable or prejudiced. It is argued here that an answer to the question "is the existing human nature sacred?" cannot be given unless another question is answered first: "why preserve our ethical way of life ?" In the remaining part of this paper, the desire to transcend existing human nature is understood by linking it to two different forms of dissatisfaction with the human way of life: it can find its origin either in the unwillingness to accept certain 'lotteries' producing all kinds of unequality among people, or in the desire to willingly lose oneself in a game of endless genetic experimentation
