Based on an excerpt (read below) from Marquis de Condorcet's The History of Human Progress (1794), he's optimistic - he constantly states to stay positive and not to fear.
Are we not arrived at the point when there is no longer anything to fear, either from new errors, or the return of old ones; when no corrupt institution can be introduced by hypocrisy, and adopted by ignorance or enthusiasm, when no vicious combination can affect the infelicity of a great people? Accordingly would it not be of advantage to know how nations have been deceived, corrupted, and plunged in misery?
Everything tells us that we are approaching the era of one of the grand revolutions of the human race. What can better enlighten us as to what we may expect, what can be a surer guide to us, amidst its commotions, than the picture of the revolutions that have preceded and prepared the way for it? The present state of knowledge assures us that it will be happy. But is it not upon condition that we know how to assist it with all our strength? And, that the happiness it promises may be less dearly bought, that it may spread with more rapidity over a greater space, that it may be more complete in its effects, is it not requisite to study, in the history of the human mind, what obstacles remain to be feared, and by what means those obstacles are to be surmounted?
While he was in prison awaiting execution by the Jacobins during the Terror, Condorcet wrote this extraordinarily optimistic prediction about the inevitability of the spread of liberty and prosperity across the globe.
Condorcet was a French philosopher of the Enlightenment and advocate of educational reform and women’s rights. He was one of the major Revolutionary formulators of the ideas of progress, or the indefinite perfectibility of humankind.
He was descended from the ancient family of Caritat, who took their title from Condorcet, a town in Dauphiné. He was educated at the Jesuit college in Reims and at the College of Navarre in Paris, where he showed his first promise as a mathematician. In 1769 he became a member of the Academy of Sciences, to which he contributed papers on mathematical and other subjects.
He died in prison at the hands of Jacobins for his liberal republican beliefs.
