Jürgen Habermas (1929-2026)
Jürgen Habermas was one of the most influential philosophers of the twentieth century. As a leading thinker of the Frankfurt School, he developed the ‘Theory of Communicative Action’.
Throughout his work, Habermas consistently emphasized the importance of democracy, the rule of law and dialogue free from coercion. In recognition of his lifelong commitment to democracy, he was awarded the Erasmus Prize in 2013.
What holds a democratic society together when its citizens differ fundamentally from one another?
This question runs like a common thread through Habermas’s work and may be more urgent today than ever.
Habermas did not seek the answer in a shared heritage, religion, or way of life, but in the possibility of engaging in dialogue with one another as free and equal citizens.
Concepts such as communicative rationality, the public sphere and constitutional patriotism form the building blocks of this democratic ideal. Yet another concept, less frequently placed centre stage, also plays an important role: solidarity.
Habermas once described solidarity as the other side of justice. Justice protects the equal freedom of every individual; solidarity refers to the mutual commitment without which that freedom is difficult to conceive.
But is that enough? Can a just democracy itself generate the solidarity it needs? Can constitutional patriotism unite people who have little else in common? And what happens when citizens are no longer willing to listen to one another’s arguments?
In this session, we will not only reflect on Habermas’s legacy but, above all, engage in discussion with Habermas. Following a brief introduction to his thought, participants will discuss several key questions in small groups, based on a text they will have read in advance. We will conclude with a plenary reflection: is solidarity indeed the flip side of justice – or is it not?
