Son of a blacksmith and cutler at Langres, Diderot entered at an early age the college of Harcourt, directed by the Jesuits. But showing no aptitude for the theological career, he was placed with a lawyer, at whose office he occupied himself exclusively with the study of literature, philosophy, and mathematics. After a time the chief of the office remonstrated with him, and asked him how he expected to live. “I am fond of study,” he replied, “I can exist on very little, I am perfectly happy; why, then, should I trouble myself about a regular profession?” On being informed of these views Diderot’s father began by stopping his son’s allowance. Then Diderot gave lessons, but not, it would seem, on very remunerative principles; for if the pupil pleased him he was ready to go on teaching him all day, whereas, in the contrary case, he did not give a second lesson. He accepted payment in the form of books, clothes, or anything else which, in the absence of money, the pupil could offer. After a time he was engaged in a private family, where for three months he taught incessantly, walking out with his pupils, taking all his meals with them, and not leaving them for a moment. He disliked, however, living in another person’s house, and retired after three months to his own garret. He was now in the direst poverty. He was often without food, and one Shrove Tuesday, in 1741 (he was then twenty-eight years of age), he returned home in a fainting condition from having eaten nothing all day. His landlady, seeing his enfeebled state, gave him some toast steeped in wine; “and I then swore,” said Diderot afterwards to his daughter, “that, if ever I possessed anything, I would not, so long as I lived, refuse help to a fellow creature who might find himself in a similar position.” On the whole, however, apart from occasional bad days, Diderot led a lively existence. He could write in any style, and was ready to execute any kind of literary work. He even composed sermons. He wrote six for a missionary, who paid him 300 crowns (about £36) for the half-dozen. This he afterwards declared to be one of the best strokes of business he had ever done. From time to time he wrote to his father, who did not answer him. His mother, however, sent him, from time to time, a portion of her savings by a faithful servant who, without saying anything about it, added to the amount some savings of her own. On these occasions the poor woman had to make a journey on foot of some 300 miles, 150 each way. In spite of this assistance Diderot was often in distress. It may be, as Heine somewhere suggests, that writers and artists, like medlars, ripen best on straw. It is certain, in any case, that the talent and courage of Diderot developed in spite, if not in consequence, of his poverty. His energy grew in proportion as he exercised his power of resistance.
