Philosophers
Jürgen Habermas
Born in 1929 in Germany, Juergen Habermas is a philosopher and social theorist representing the second generation of the Frankfurt School. In The Theory of Communicative Action he proposed a dialogical rationality as an alternative to instrumental reason, and in The Structural Transformation of the Public Sphere he traced the rise and decline of the bourgeois public sphere. He laid the theoretical foundations of discourse ethics and deliberative democracy, defending the Enlightenment as an 'unfinished project.'
