Note 90 — Chapter II · (continued 2)

In the first halt of the perpetuum mobile, i. e., in the suspension of the function of money as a medium of circulation, Boisguillebert at once suspects its independent existence from commodities. Money, he says, must be “in constant motion, it can be money only by being mobile, but as soon as it becomes motionless all is lost.” (“Dans un mouvement continuel, ce qui ne peut être que tant qu’il est meuble, mais sitôt qu’il devient immeuble tout est perdu.” (“Le Détail de la France,” p. 231.) What he overlooks is that this halt constitutes the condition of its movement. What he really wants is that the value form of commodities should appear merely in the transitory form of their change of matter, but should never become an end in itself.
