[Reflections derived from report: The Lancet commission on medicine, nazism, and the holocaust: historical evidence, implications for today, teaching for tomorrow].

Although, in principle, the Lancet article Commission on Medicine, Nazism, and the Holocaust, aims to provide medical students with a moral compass to guide the future of medical practice as a social retaining wall against anti-Semitism, it deals with the Holocaust not from a philosophical point of view, but from a pedagogical one, resorting to didactic strategies from a historiographical approach. What seemed to be a plea against the behaviour of the Nazi doctors' experiments becomes a justification of the positive law of the liberal democracies in use. However, what it ignores is of the utmost importance: that the majority of the regime's doctors were tried and sentenced for their iniquitous actions, and yet, in contemporary Western society, an even greater danger is very much present: techno-science, which, as it stands, can once again compromise the identity, dignity and very life of the human person. Going deeper into the causes, the target of our study, and preventing their repetition means rethinking human nature from the perspective of aristotelian-thomistic thought, which is the basis of the moral laws that derive from the natural law. This moral rearmament supposes assuming, from philosophical realism, the ontological order of being, the anthropological order of being-with, insofar as reason knows as the order of ought to be, which is transmuted into an ethical order thanks to the exercise of the freedom of the human person.
