Abstract
Notions of human nature and what is natural are vague and contradictory within the field of bioethics, especially evident through individuals critical of bodily diversity through nanobiology and biotechnology in general. This paper discusses the paradoxical aspects of these notions of human nature, while showing that they rely on a notion of a standard body that all humans allegedly share. I examine several writings on biotechnology by bioethicists, specifically by people working in policy—it is here that the normativity of human nature becomes a pressing concern. Once it has been shown that there is no standard body, and indeed typical bioethical notions of human nature are internally contradictory, a more productive conversation can be engaged in that allows for morphological diversity, be it through biotechnological change or via nature itself.
