In this article, I argue that concern with the public sphere and the necessary conditions for a genuine democracy can be seen as a central theme of Jurgen Habermas's work that deserves respect and critical scrutiny in the contemporary moment, when throughout the world liberal democracies are in crisis. My study intends to point to the continuing importance of Habermas' problematic of the public sphere and its relevance for debates over democratic politics and social and cultural life in the present age, in an era in which the Occupy Movements, Black Lives Matter, #MeToo, the Trump Resistance Movement, and Ukraine and Palestine Solidarity groups use social media to struggle against multiple forms of oppression. At stake is delineating a concept of the public sphere which facilitates maximum public participation and debate over the key issues of the contemporary era and which consequently promotes the cause of radical democracy and social transformation.
