I want to know the answer to the following question:
Coffehouses were essential to what movement by becoming centers of free-thinking and self-discovery?
All the background I'm provided with is that "Coffeeshops became homes away from home for many who sought, for the first time, to engage in discourse with their neighbors and discuss intriguing and thought-provoking matters, especially those regarding philosophy to politics.". Is that enough to answer the question?
Answer: no
