Two thinkers of the French Enlightenment, Anne-Robert-Jacques Turgot, Baron de Laume (1727-81), and  Marie Jean Caritat, Marquis de Condorcet (1743-1794), integrated reflection on scientific discoveries into their writings on progress. Turgot, a minister to Louis XVI, produced two influential works, A Philosophical Review of the Successive Advances of the Human Mind and On Universal History.  Condorcet was inspired by Turgot to write Outlines of an historical view of the Progress of the human mind, a piece that echoes many of Turgot's convictions.  Although Condorcet wrote his essay in prison during the Terror, he, like Turgot, evinces optimism about the future of France and of humanity as a whole.
