Abstract

According to Hans Jonas (1903–1993), the modern technological progress endowed humanity with wondrous power, which in the long run risks altering the nature of human action. This is especially true for the realm of collective action, the effects of which evidence an unpredicted issue: the ecological crisis, which is the “critical vulnerability” of nature to technological intervention. This discovery brings to light that the whole biosphere of the planet has been added to that which human beings must be responsible for because of their power over it. There is, however, a further dimension of vulnerability (and responsibility) to be considered, namely the one which characterizes organic life as such. Indeed, the essence of all living organisms–human beings included–is characterized by vulnerability, given their precarious and unstable condition of “needful freedom” towards the environment. Nevertheless, terrestrial life fl ourished through a multifaceted and unplanned (thus, again, vulnerable) evolution of living forms, ranging from bacteria to human beings – these evidencing a unique degree of freedom, which Jonas refers to as a “metaphysical gap” towards other living beings. The problem is that the present-day technology provides the possibility to manipulate the very essence of life and human nature. Is this process to be accepted and accomplished? And what about the related risks? Indeed, according to Jonas, issues such as genetic manipulation, euthanasia, organ transplantation, assisted reproduction, exploitation of other living beings etc., raise ethical dilemmas which can be addressed thanks to the idea of vulnerability.
