Jürgen Habermas

Jürgen Habermas was one of the most important philosophers of the 20th century. His work on the public sphere, communicative action, and deliberative democracy shaped not just philosophy but sociology, political science, and law. He argued that genuine democracy requires open, reasoned public debate — an idea that has become even more relevant in the age of social media and misinformation. He continued publishing into his 90s.
