Current philosophical literature is saturated with the debate on biomedical enhancement, where bio-liberals and conservatives alike make compelling arguments for and against the enterprise. However, this literature is yet to consider the impact such enhancement would have on the individual’s actual lived experience. This article seeks to remedy that by situating the bioethics debate within the phenomenology of Maurice Merleau-Ponty, specifically theorising how biomedical enhancement of the physical kind would impact Merleau-Ponty’s notion of the body-subject. The central issue arises when (...) the reciprocal relationship between the physical body and phenomenal world (termed “body/world dynamic”) is shown to be off-balance because of the rapid rate at which human beings continue to “enhance” their environment. In this, we see that the development of the world has outweighed that of the body to the extent that we, as body-subjects, have become maladapted to the place we call home. This article will suggest that we can attempt to resolve this by restoring the balance of the body/world dynamic with “restrictive” enhancement, thereby providing an ethical justification for the pursuit of the enterprise.
