Abstract
As one of the most prominent figures of dystopic posthumanism Francis Fukuyama views biotechnological revolution as presumably the most dangerous challenges we are going to face in what he calls our posthuman future. In his opinion human enhancement will lead inevitably to some forms of eugenic practices, blurring the difference between humans and other live forms, posing the problem of legal status of modified individuals, etc. Hence he calls for establishment of a new regulatory instruments for controlling biotechnological research and development. Those instruments, Fukuyama says, should refer to and protect his original notion of human nature. In the article I try to criticaly examine the way Fukuyama constructs this notion.
