Division of labor is the law of all existing things and therefore it should be present in human societies.  It is very possible that this is so; but still the question remains of what nature is that division of labor which I behold in my human society? Is it that division of labor which should exist?  And if people regard a certain division of labor as unreasonable and unjust then no science whatever can convince men that that should exist which they regard as unreasonable and unjust.
