Considered in its essence, the division of labor is the way in which equality of condition and intelligence is realized. Through diversity of function, it gives rise to proportionality of products and equilibrium in exchange, and consequently opens for us the road to wealth; as also, in showing us infinity everywhere in art and Nature, it leads us to idealize our acts, and makes the creative mind--that is, divinity itself, mentem diviniorem--immanent and perceptible in all laborers. Division of labor, then, is the first phase of economic evolution as well as of intellectual development: our point of departure is true as regards both man and things, and the progress of our exposition is in no wise arbitrary. But, at this solemn hour of the division of labor, tempestuous winds begin to blow upon humanity. Progress does not improve the condition of all equally and uniformly, although in the end it must include and transfigure every intelligent and industrious being. It commences by taking possession of a small number of privileged persons, who thus compose the elite of nations, while the mass continues, or even buries itself deeper, in barbarism. It is this exception of persons on the part of progress which has perpetuated the belief in the natural and providential inequality of conditions, engendered caste, and given an hierarchical form to all societies. It has not been understood that all inequality, never being more than a negation, carries in itself the proof of its illegitimacy and the announcement of its downfall: much less still has it been imagined that this same inequality proceeds accidentally from a cause the ulterior effect of which must be its entire disappearance. Thus, the antinomy of value reappearing in the law of division, it is found that the first and most potent instrument of knowledge and wealth which Providence has placed in our hands has become for us an instrument of misery and imbecility. Here is the formula of this new law of antagonism, to which we owe the two oldest maladies of civilization, aristocracy and the proletariat: Labor, in dividing itself according to the law which is peculiar to it, and which is the primary condition of its productivity, ends in the frustration of its own objects, and destroys itself, in other words: Division, in the absence of which there is no progress, no wealth, no equality, subordinates the workingman, and renders intelligence useless, wealth harmful, and equality impossible. All the economists, since Adam Smith, have pointed out the ADVANTAGES and the INCONVENIENCES of the law of division, but at the same time insisting much more strenuously upon the first than the second, because such a course was more in harmony with their optimistic views, and not one of them ever asking how a LAW can have INCONVENIENCES. This is the way in which J. B. Say summed up the question:--
