" All earlier revolutionary appropriations were restricted; individuals, whose self-activity was restricted by a crude instrument of production and a limited intercourse, appropriated this crude instrument of production, and hence merely achieved a new state of limitation. Their instrument of production became their property, but they themselves remained subordinate to the division of labour and their own instrument of production. In all expropriations up to now, a mass of individuals remained subservient to a single instrument of production; in the appropriation by the proletarians, a mass of instruments of production must be made subject to each individual, and property to all. Modern universal intercourse can be controlled by individuals, therefore, only when controlled by all. "
