““In fact, the words perfectibilité and civilisation made their first appearance in any European language in the 1750s. The adjective ‘social’ acquired currency at the same time, pointing to a new secular order, civil society, which was distinct from the state and from religion. Only a few years separated the publication of such major works of enlightened philosophy as Buffon’s Natural History and Condillac’s Treatise on Systems in 1749 and Montesquieu’s hugely influential The Spirit of the Laws in 1748.””
