[Human reason versus arrogance technoscience and the replacement shadow. -Ethical evaluation and social control to regain power on the means and ends from the work of José Sanmartín].

This essay analyzes from a personalistic bioethics the model of technological progress supported by an autonomy without controls and an imperative that is governed by the maxim: if it can be done, let's do it!, as a necessary and sufficient condition of progress. This puts us on the slippery slope between the technically feasible and the morally lawful. The pioneering work of the philosopher, José Sanmartin Esplugues 2 , urges reflection in the face of a technological profusion that sees the human being as a useful embodied object and offers powers of intervention on human life that were previously unimaginable. The reduction of the person to mere biological-material data opens the door to increasing deshumanization by subordination to the calculations of an instrumental rationalism. Underlying the desire to see ourselves at the top of the world and genetic techniques are the ultimate expression of a longing for human emancipation that aspires to take the reins of evolution through an abstract postbiological imaginary. Sanmartin proposes a model of ethical evaluation and social insertion of technoscientific activity that goes beyond the conventional categories of impact, use and effectiveness to distinguish social, cultural, economic, political and values correlates, in order to embroider a pattern that decides on the means and ends of human life through technologies that are neither innocuous nor neutral. A society without antidotes to manipulation that also teaches us to cultivate utopian dreams about human nature is easily malleable by elites who promise happy worlds and redeem us from our vulnerability.
