The encyclopedia project reflected the age of Enlightenment because it was a project to educate the general population. It didn't just offer to educate the people of the upper classes, but the encyclopedia as it contained so much information about a vast number of different things, it let the people who wouldn't normally have as much information have an opportunity to have a broader view on a number of aspects. Denis Diderot was the co-founder, chief editor and contributor the Encyclopedia with Jean le Rond D'Alembert.
