I want to know the answer to the following question:
How was the public sphere defined?
All the background I'm provided with is that "One of the primary elements of the culture of the Enlightenment was the rise of the public sphere, a "realm of communication marked by new arenas of debate, more open and accessible forms of urban public space and sociability, and an explosion of print culture," in the late 17th century and 18th century.". Is that enough to answer the question?
Answer: yes
