Biotechnological experiments on 'human material'1 are therefore associated with particular socio-cultural, legal, scientific and religious responsibilities, since they potentially awaken a logic of self-referential creation that can lead to the exclusion of any other methodology, alien to its 'objective' purposes. It is important to remember that many of the difficulties faced by researchers are ethical in nature. There is an emerging need for a discussion, including in the field of law, that can work out the limits of experimental research and impose an obligation to give up and understand the imperfections of the ontological capacities of human beings.
