Can any one tell me where this quote from Diderot comes from?

Question

“We can call the eighteenth century the age of the enlightenment because it was both a culmination and a new beginning. Fresh currents of thought were wearing down institutionalized traditions. New ideas and new approaches to old institutions were setting the stage for great revolutions to come.”

Answer 1

Diderot didn't say that.  The quote comes from someone writing about Diderot and his kind.  From the looks of the sources below, the someone was Gerhard Rempel, faculty member of Western New England College.
