The article deals with present day challenges related to the employ of technology in order to reduce the exposition of the human being to the risks and vulnerability of his or her existential condition. According to certain transhumanist and posthumanist thinkers, as well as some supporters of human enhancement, essential features of the human being, such as vulnerability and mortality, ought to be thoroughly overcome. The aim of this article is twofold: on the one hand, we wish to carry out (...) an enquiry into the ontological and ethical thinking of Hans Jonas, who was among the first to address these very issues with great critical insight; on the other hand, we endeavour to highlight the relevance of Jonas’ reflections to current challenges related to bioscience and biotechnological progress. In this regard, we believe that the transcendent and metaphysical relevance of the «image of man» introduced by Jonas is of paramount importance to understand his criticism against those attempts to ameliorate the human being by endangering his or her essence.

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.

El presente aporte trata de reconstruir el largo recorrido intelectual de Hans Jonas que parte de la gnosis tardía, pasa por la filosofía de la biología, la ética y llega a la bioética. Este trabajo se propone como objetivo evidenciar la posición de Jonas confrontándola con aquellas de las cuales ha partido. En pocas palabras, intenta ser apenas una introducción de este fascinante filósofo de nuestro tiempo.
