Entwickelung der Gesetze des menschlichen Verkehrs, und der daraus fließenden Regeln für menschliches Handeln [Development of the laws of human intercourse, and the rules following therefrom for human action](en alemán). Braunschweig, (Germany): Friedrich Vieweg und Sohn. p. 231. "... nur durch Feststellung des Privateigenthums ... deren Lösung die Kräfte einzelner Menschen weit übersteigt." ("... only through the establishment of private property is to be found the measure for determining the quantity of each commodity which it would be best to produce under given conditions. Therefore, the central authority [that is] proposed by the communists for the distribution of the various tasks and their reward, would very soon find that it had undertaken a task the solution of which far exceeds the abilities of individual men.")
