Ancients and Moderns down to the Encyclopædia, and from Bossuet and
Corneille down to Jean Jacques and Diderot. When he was born, the man of
letters did not exist. When he died, the man of letters was the most
conspicuous personage in France. But when Diderot first began to roam
about the streets of Paris, this enormous change was not yet complete.

For some ten years (1734-1744) Diderot's history is the old tale of
hardship and chance; of fine constancy and excellent faith, not wholly

in a shipwreck, only made for answer, _Jubet me fortuna expeditius
philosophari_. Once he had the good hap to be appointed tutor to the
sons of a man of wealth. He performed his duties zealously, he was well
housed and well fed, and he gave the fullest satisfaction to his
employer. At the end of three months the mechanical toil had grown
unbearable to him. The father of his pupils offered him any terms if he
would remain. "Look at me, sir," replied the tutor; "my face is as
yellow as a lemon. I am making men of your children, but each day I am
