Rousseau believes that "labor is the unshirkable responsibility of people in society. Any citizen, rich or poor, strong or weak, is a hooligan as long as he does not work. " Only labor can make people "live a free, healthy, honest, hardworking and upright life." Rousseau asked Emil to study agricultural labor first, because agriculture is the most honest and beneficial to mankind. But he also made it clear to the Amir that agricultural workers were bound to the land and had no freedom. So Emil must learn another labor skill. He believes that among all the occupations in which human beings can make a living, manual labor is the most close to the natural state, and carpentry is the most beneficial and suitable for students' interest. Woodworking can make people nimble and alert, and develop people's sense of beauty and elegance. He asked Emil to go to the carpenter's workshop two days a week to learn carpentry skills. The education in this period made Emil have both the hands of a craftsman and the mind of a philosopher.
