Farming, according to Rousseau, is the most honourable of industries. After farmers he places blacksmiths and carpenters. Berquin brings his children into a natural contact with men of various crafts, the farmer, the blacksmith, the mason. They watch the building of a house and learn the need for division of labour. He can dispense with Rousseau’s artifice. He never hampers himself with theory, but allows Emile’s virtues to appear in common adventures with men and birds and animals.
