In spite, however, of this fundamental difference between these schools, both assumed the premise that, at the beginning, individuals were _free_, _equal_ politically and economically, and that it was from such an original social order there had developed, through gradual differentiation, the fully developed State with its class hierarchy. This is the _law of previous accumulation_.
But we should err if we believed that this thesis was originally intended as a historical account. Rationalism is essentially unhistoric, even anti-historic. On the contrary, the thesis was originally put forward as a “fiction,” a theory, a conscious unhistorical assumption. In this form it acquired the name of _natural law_. It was under this name that it came into modern thought, tinctured stoically in Grotius and Puffendorf, and epicureanally in Hobbes. It became the operative weapon of thought among the rising third estate of the capitalists.
The capitalists used the weapon, first against the feudal state with its privileged class, and, later against the fourth estate, with its class theory of Socialism. Against the feudal domination it argued that a “Law of Nature” knows and permits no privileges. After its victories in the English Revolution of 1648, and the great French Revolution of 1789, it justified, by the same reasoning, its own _de facto_ pre-eminence, its own social and economic class superiority, against the claims of the working classes. According to Adam Smith, the classes in a society are the results of “natural” development. From an original state of equality, these arose from no other cause than the exercise of the economic virtues of industry, frugality and providence. Since these virtues are pre-eminently those of a bourgeoisie society, the capitalist rule, thus sanctioned by natural law, is just and unassailable. As a corollary to this theorem the claims of Socialism cannot be admitted.
Thus, what originally was put forward as a “fiction,” became first, a hypothesis and finally the _axiom_ of all bourgeoisie sociology. Those who support it accept the axiom as self-evident, as not requiring proof. For them, class domination, on this theory, is the result of a gradual differentiation from an original state of general equality and freedom, with no implication in it of any extra-economic power. Robert Malthus applied this alleged law to the future, in his attempt to demonstrate any kind of Socialism to be purely Utopian. His celebrated _Law of Population_ is nothing but the _law of original accumulation_ projected into the future. He claims that if any attempt were made to restore the state of economic equality, the workings of the law would have the effect--because of the difference in economic efficiency--of restoring modern class conditions. All orthodox sociology begins with the struggle against this supposed law of class formations. Yet every step of progress made in the various fields of the science of sociology, has been made by tearing up, one by one, the innumerable and far-spreading roots which have proceeded from this supposed axiom. A sound sociology has to recall the fact that class formation in historic times, did not take place through gradual differentiation in pacific economic competition, but was the result of violent conquest and subjugation.
