Problem: Question: "What philosopher participated?" Context: "The Republic of Letters was the sum of a number of Enlightenment ideals: an egalitarian realm governed by knowledge that could act across political boundaries and rival state power. It was a forum that supported "free public examination of questions regarding religion or legislation".

They were also commonly donated to mosques, which often amassed large collections of them." Answer:
