  Of particular interest in current philosophical debates about justice and the genome is the consensus which has emerged among participants that our usual ways of thinking about justice are themselves challenged by the new genetic technologies (Buchanan et al.  2000).[64] Theories of justice are typically based on conceptions of human nature, but with the capacity to remake human nature, this foundation disappears. Approaches to distributive justice seek to compensate for natural inequalities existing at birth among individuals of fixed identities, but considerations of justice are now implicated earlier, in decisions about the distribution of genetic characteristics, decisions which affect the identities of those born. The potential for genetic stratification places at risk the assumption central to all theorizing about justice—that we share a moral community.
