Abstract:In the Economic Manuscripts of 1857—1858, Marx presents a systematic critique of capital power through labor discourse. By examining the historical evolution of wage labor from a materialist historical perspective, it reveals how laborers undergo threefold negation, losing ownership of both means of production and means of living, ultimately being propelled into the labor market under conditions of double freedom where they own nothing. The analysis of the dominated rights of wage labor explores the unity of capital and labor's opposing relationship: in an oppositional sense, the ability of living labor to preserve and transfer old value refl ects capital's self-preservation ability, while the productivity of labor unions represents the productivity of capital; their unity manifests as an unequal mutual dependence. In a specifi c context, the capital is referred to as dead labor, objectifi ed labor, unproductive labor, and total labor. The alienation of labor in relation to objective labor conditions, one's labor capability, and labor products exposes capital's exploitation of labor. The capital is described as a "living contradiction" that creates conditions for its own demise while promoting the unity of the proletariat, leading to the proletariat's goal of "using capital to eliminate capital", thereby restoring general labor and free time to the laborers themselves. Examining the capital through the lens of labor discourse not only offers an alternative perspective for critiquing the capital power but also provides signifi cant insights for advancing the unity of the contemporary proletariat and transforming social relations.
