The public sphere is a space where individuals come together to discuss and debate societal issues, forming public opinion. It is often associated with areas like cafes, parks, and online platforms where people can freely express their thoughts and engage in dialogue. The concept emphasizes the importance of open communication in a democratic society. Historically, the idea of the public sphere was popularized by philosopher Jürgen Habermas, who argued that it plays a crucial role in fostering democracy and accountability. In this space, citizens can challenge authority and influence political decisions, making it essential for a healthy civic life.
