Why Habermas Remains Urgently Relevant

At a time when public debate can seem to be running out of steam, the thinking of German philosopher Jürgen Habermas stands out as a singular compass and remains strikingly relevant today, as it offers a way of thinking about secular modernity, the place of religion, the nation-state and nationalism in a European context, and critical thought more broadly, all through the lens of “discourse ethics” and “dialogue free of domination.”

Within this framework, Habermas rejects the notion that good and evil can be defined by an absolute authority, a fixed tradition or an unquestionable metaphysical truth. Instead, he argues that they must be worked out rationally among free and equal individuals in an open space for dialogue.

Born in 1929 into a Germany in crisis, Habermas grew up in a relatively sheltered bourgeois household, yet one marked by the ideological divisions of the era. His father joined the Nazi Party – a heavy family legacy in a context where allegiance to the regime had become, for many, as much a social expectation as a political constraint. As a child, Habermas also suffered from a cleft lip, a visible disability in a society that had little tolerance for physical difference. Several surgical procedures marked his childhood, adding to an early experience of vulnerability and of being subject to social scrutiny.

As a teenager, he was briefly a member of the Hitler Youth, like nearly everyone of his generation. The end of the war and the gradual discovery of the crimes of Nazism came as a formative shock. This rupture – between indoctrination, reconstruction and the need to think anew – would play a decisive role in shaping his later reflections on memory and reason.

In the postwar years, he studied in a Germany still shaped by intellectual figures compromised by their ties to the Nazi regime. While still young, he mounted a forceful critique of Martin Heidegger, focusing in particular on Heidegger’s silence about, and involvement in, the Nazi era. The essay caught the attention of Theodor W. Adorno, a leading figure of the Frankfurt School, who brought him on as an assistant.

Habermas initially worked within that critical tradition but gradually moved away from it. Where the Frankfurt School’s early thinkers developed a pessimistic view of modernity and reason, he retained a strong faith in the capacity of language and discussion to foster social bonds and rationality.

It was in this context that he developed what he called discourse ethics. A norm is legitimate, he argued, only if it can be accepted by everyone affected by it through dialogue free of domination. Morality, then, rests not on some external truth but on the quality of the deliberative process itself. Unlike Socrates, who sought to draw out a truth presumed to already exist, Habermas emphasizes procedure: it is the discussion itself that establishes validity.

This line of thinking led to his theory of “communicative action.” Language, for Habermas, is not merely a tool for exchange but a space structured by implicit demands: truth, sincerity and rightness. To speak is already to enter into a relationship of mutual recognition. From this follows his conception of the public sphere, envisioned as a site of democratic deliberation where citizens exchange and weigh arguments as equals.

That vision extends to his political thinking on constitutional patriotism: political belonging, in this framework, no longer rests on national or cultural identity, but on a commitment to the democratic principles guaranteed by the Constitution. This idea is rooted in his rejection of nationalism, which the history of twentieth-century Germany made particularly problematic.

Continuing along these lines, his commitment to Europe seeks to move beyond the power politics of nation-states – not to weaken Germany, but to prevent any one nation from dominating the continent. Europe thus becomes a space where cooperation and dialogue take precedence over power struggles.

Later in his career, Habermas also revisited the question of religion. Long reserved toward religion, he came to adopt a more open position: the point is neither to incorporate faith into philosophy nor to reject it as irrational, but to recognize that it can still contain moral resources of value to public debate.

Religions, in his view, no longer provide comprehensive worldviews, but they continue to transmit essential ethical insights: attentiveness to human vulnerability, a sense of responsibility, recognition of suffering, and a commitment to solidarity. He also stresses that secular modernity did not emerge in a total break with religion but retains some of its legacies.

Habermas is, in short, a philosopher of striking contemporary relevance, one well worth discovering or revisiting.
