Abstract

The article considers human enhancement from the perspective of liminality. It defines the concept of liminality, introduced by ethnologist van Gennep in an attempt to generalise the rites of passage. It shows how, thanks to Turner, this concept has spread beyond anthropology to characterise the many situations ‘betwixt and between’ associated with transitioning from the original social structure to the new one. The article points out that, by definition, liminal situations break down traditional structures; hence, polemical debates on whether to allow human enhancement cannot be conducted from the position of existing normative standards. It argues, on the contrary, that these must be fundamentally expanded so as to reflect the current transitional phase from treatment to enhancement and that preparations must be made for the policies and institutions that will deal with the consequences. Otherwise, we will face threat of a new kind of totalitarianism.
