Step 1: Understanding Jurgen Habermas’ concept of the public sphere.
Habermas' idea of the public sphere refers to a space where individuals can come together and discuss matters of public interest in an open, rational, and communicative environment. This sphere facilitates public debate and the formation of public opinion, which is free from state or commercial interference.
