The schooldays were all too short. The practical master-cutler at Langres soon intimated to Denis that it was time to choose a profession. But Denis declines to be a doctor, because he has no turn for murder; or a lawyer, because he has no taste for doing other people’s business. In brief, he does not want to be anything. He wants to learn, to study, to look round him. But a shrewd old tradesman is not going to give, even if he could afford to give, any son of his the money to do that. Denis had at home a younger brother, who was to be a priest (‘that cursed saint,’ the graceless Denis called him hereafter), a sister, good and sensible like her father, and a mother, who was tender and foolish over her truant boy, after the fashion of mothers all the world over. Here were three mouths to feed. Denis loved his father with all the impetuous affection of his temperament. He was delighted when, some years later, he went back to Langres and a fellow-townsman grasped him by the arm saying: ‘M. Diderot, you are a good man, but if you think you will ever be as good a man as your father, you are much mistaken.’ But Diderot had never the sort of affection that consists in doing one’s utmost for the object of the affection. He preferred to be a care and a trouble to his family and to live by his wits, harum-scarum, merry, and poor. He chose that life, and abided by the choice for ten years. Three times in that period the old servant of the family tramped all the way from Langres to Paris with little stores of money hidden in her dress for this dear, naughty scapegrace of a Master Denis; but except for this, he lived on his wits in the most literal sense of the term. He made catalogues and translations; he wrote sermons and thought himself well paid at fifty écus the homily; he became a tutor--until the pupil’s stupidity bored him, when he threw up the situation and went hungry to bed. He once indeed so far commanded himself as to remain in this capacity for three months. Then he sought his employer; he could endure it no more. ‘I am making men of your children, perhaps; but they are fast making a child of me. I am only too well off and comfortable in your house, but I must leave it.’ And he left.
