Labor (n.) is a kind of productive activity, not a burden, but the distinctive human trait.
Labor (n.) is external to the laborer. . . . It is not part of his nature... consequently he does not fulfill himself in his labor but denies himself. . . . The laborer therefore feels himself at home only during his leisure time, whereas at work he feels homeless.
Labor (n.) is external to the worker rather than intrinsic to his nature. Therefore, in his work he does not affirm himself but denies himself, does not feel content but unhappy, does not develop freely his physical and mental energy but mortifies his body and his mind. The worker therefore only feels himself outside his work, and in his work feels outside himself.
Labor (n.) produces marvels for the rich but deprivation for the worker. It produces palaces, but hovels for the worker. It produces beauty, but deformity for the worker. It replaces labor by machines, but it throws one section of the workers back to barbaric labor, and it turns the remainder into machines.
Labor (n.) comes to belong to the object rather than to the laborer despite the fact that the laborer had put his life into the object.
Labor (n.) is the essence of human life. A thing produced (i.e. A statue, a house, or a piece of cloth) is therefore the essence of human life made into a physical object.
Labor (n.) is the father of material wealth, the earth is its mother.
