This project is a clue to understanding why so much of the philosophical and religious speculation of the 16th and 17th centuries consists of a true vivisection of the human body, whereby it was decided which of its properties could live and which, instead, had to die. It was a social alchemy that did not turn base metals into gold, but bodily powers into work-powers. For the same relation that capitalism introduced between land and work was also beginning to command the relation between the body and labor. While labor was beginning to appear as a dynamic force infinitely capable of development, the body was seen as inert, sterile matter that only the will could move, in a condition similar to that which Newton's physics established between mass and motion, where the mass tends to inertia unless force is applied to it. Like the land, the body had to be cultivated and first of all broken up, so that it could relinquish its hidden treasures. For while the body is the condition of the existence of labor-power, it is also its limit, as the main element of resistance to its expenditure. It was not sufficient, then, to decide that in itself the body had no value. The body had to die so that labor-power could live.
Silvia Federici, Caliban and the Witch, pp. 140-141.
The project to which Federici refers is the social transformation of the body into a work-machine. She works through Descartes and Hobbes to examine what she claims is a bourgeois spirit whereby work is “the condition and motive of existence of the body” and all bodily powers need to be transformed into work powers.
