[The application of technoscience to man: ethical discernment in relation to the transhumanist-posthumanist proposal]

Transhumanism-posthumanism is a current of thought that appears closely linked to the development of technoscience and its application to man. At the same time that this current must be subject to criticism, an anthropological and ethical paradigm must be illuminated that allows accepting or not the new technoscientific advances, making a discernment between them. Such discernment should lead us to weigh the goodness of these advances, rejecting only those that represent a degradation of the human being, and accepting those that help man to be more fully man. To do this, the article proposes starting the discernment from an ethical principle such as respect for the integrity of man. Together with him, it is necessary to act with caution regarding human health, considered in relation to his psychosomatic unity. It will also be necessary to avoid deriving the ethics of the advances from the same technoscience. Finally, discernment requires, ultimately, starting from an idea about what man is, proposing the need to do so from a dual rather than dualistic conception of the human person. Based on all of the above, various ethical criteria are indicated in the work that complete the principle of respect for human integrity indicated above: respect and promote human life in all its dimensions, use of technology at the service of human beings in a controlled manner and that report social benefit or value by each technique, not only from a therapeutic perspective, but also from the improvement of the human psychosomatic unit. In conclusion, it is necessary to recognize in man the uniqueness of him as he is a bodily being who knows and loves in freedom, whose ends are not limited to material or sensible things, but which are only achievable in and from his own material condition. Consequently, any techno-scientific intervention that substantially alters his body condition is inhuman, not instead when it repairs or enhances -without abolishing them- his own qualities.
