"The Structural Transformation of the Public Sphere" is a seminal work by Jürgen Habermas that explores how public discourse has evolved over time. Habermas argues that the public sphere, a space for rational debate and discussion among citizens, emerged in the 18th century with the rise of bourgeois society and print media. This space allowed individuals to engage in critical discussions about politics and society, fostering democratic ideals. However, Habermas also highlights the decline of the public sphere in modern times, influenced by factors such as mass media and consumer culture. He suggests that these changes have led to a more fragmented and commercialized public discourse, undermining the original democratic purpose of the public sphere.
