Jürgen Habermas: a prophetic voice in the face of contemporary excesses in bioethics
The death of Jürgen Habermas on 14 March at the age of 96 marks the passing of one of Europe’s great philosophical minds, whose work has consistently shed light on the ethical challenges of modernity, particularly in the field of science and technology. A leading figure in critical philosophy, Habermas profoundly influenced contemporary debates in bioethics, particularly through his reflections on what he termed ‘liberal eugenics’.
As early as the early 2000s, in *The Future of Human Nature* (trans. Gallimard, 2002), the German philosopher warned of the anthropological changes brought about by advances in biotechnology, particularly in the fields of prenatal diagnosis and embryo selection. Contrary to a purely technocratic or individualistic view, Habermas emphasised the ‘intersubjective’ implications of these practices: choosing the genetic characteristics of an unborn child is not merely a matter of individual freedom, but affects the very structure of the relationship between parents and children, as well as the fundamental equality between human beings.
His concept of ‘liberal eugenics’ was specifically intended to expose an insidious drift: that of genetic selection no longer imposed by the state, as in the totalitarian eugenics of the 20th century, but encouraged by the market, social norms and parental expectations. In this context, Habermas presciently foresaw that freedom of choice would quickly risk becoming a diffuse constraint, guided by criteria of performance, health or social conformity.
Recent developments in national and European legislation regarding prenatal screening seem to lend particular resonance to these warnings. The expansion of genetic testing (detection of an ever-increasing number of ‘risks’; non-invasive prenatal testing; pre-implantation diagnosis as part of assisted reproductive technology, or even pre-conception testing), their widespread adoption (systematic recommendation by healthcare professionals and coverage by the National Health Service) and their integration into routine medical care are contributing to a silent transformation of social norms.
The risk, already identified by Habermas and now evident in more ways than one, is that of a shift towards a form of systematic selection, where certain human lives would be deemed less worthy of being lived.
Born himself with a slight deformity (a cleft lip) and having witnessed in his youth the horrors of eugenic policies (Aktion T4 in particular) based on Nazi ideology, this experience undoubtedly fostered in him a lasting mistrust of any form of power that claims to define the value of human lives.
InThe Future of Human Nature, however, Habermas emphasises that the danger no longer lies in coercion imposed by an authoritarian regime, but in a diffuse, socially internalised normalisation that could lead to more subtle yet equally problematic forms of exclusion.
From this perspective, Habermas’s thinking invites us to fundamentally re-examine certain practices in the field of bioethics. It reminds us that human dignity cannot be conditioned by biological or functional criteria, and that scientific advances must be guided by rigorous ethical reflection, grounded in respect for autonomy, the dignity of each individual and the equality of all.
Now more than ever, at a time when genetic technologies and artificial intelligence are opening up entirely new fields, Jürgen Habermas’s intellectual legacy serves as an essential guide. His prescient critique urges us not to succumb to a purely utilitarian or technological logic, but to preserve what underpins our shared humanity: mutual recognition between free and equal individuals.
