If, then, I demonstrate that political economy, with all its contradictory hypotheses and equivocal conclusions, is nothing but an organization of privilege and misery, I shall have proved thereby that it contains by implication the promise of an organization of labor and equality, since, as has been said, every systematic contradiction is the announcement of a composition; further, I shall have fixed the bases of this composition. Then, indeed, to unfold the system of economical contradictions is to lay the foundations of universal association; to show how the products of collective labor COME OUT of society is to explain how it will be possible to make them RETURN to it; to exhibit the genesis of the problems of production and distribution is to prepare the way for their solution. All these propositions are identical and equally evident. % 1.--Antagonistic effects of the principle of division. All men are equal in the state of primitive communism, equal in their nakedness and ignorance, equal in the indefinite power of their faculties. The economists generally look at only the first of these aspects; they neglect or overlook the second. Nevertheless, according to the profoundest philosophers of modern times, La Rochefoucault, Helvetius, Kant, Fichte, Hegel, Jacotot, intelligence differs in individuals only QUALITATIVELY, each having thereby his own specialty or genius; in its essence,--namely, judgment,--it is QUANTITATIVELY equal in all. Hence it follows that, a little sooner or a little later, according as circumstances shall be more or less favorable, general progress must lead all men from original and negative equality to a positive equivalence of talents and acquirements. I insist upon this precious datum of psychology, the necessary consequence of which is that the HIERARCHY OF CAPACITIES henceforth cannot be allowed as a principle and law of organization: equality alone is our rule, as it is also our ideal. Then, just as the equality of misery must change gradually into equality of well-being, as we have proved by the theory of value, so the equality of minds, negative in the beginning, since it represents only emptiness, must reappear in a positive form at the completion of humanity's education. The intellectual movement proceeds parallelly with the economic movement; they are the expression, the translation, of each other; psychology and social economy are in accord, or rather, they but unroll the same history, each from a different point of view. This appears especially in Smith's great law, the DIVISION OF LABOR.
