every society based upon the production of commodities has this peculiarity: that the producers have lost control over their own social inter-relations. Each man produces for himself with such means of production as he may happen to have, and for such exchange as he may require to satisfy his remaining wants. No one knows how much of his particular article is coming on the market, nor how much of it will be wanted. No one knows whether his individual product will meet an actual demand, whether he will be able to make good his costs of production or even to sell his commodity at all. Anarchy reigns in socialized production. But the production of commodities, like every other form of production, has it peculiar, inherent laws inseparable from it; and these laws work, despite anarchy, in and through anarchy. They reveal themselves in the only persistent form of social inter-relations — i.e., in exchange — and here they affect the individual producers as compulsory laws of competition. They are, at first, unknown to these producers themselves, and have to be discovered by them gradually and as the result of experience. They work themselves out, therefore, independently of the producers, and in antagonism to them, as inexorable natural laws of their particular form of production. The product governs the producers. […] *With the seizing of the means of production by society, production of commodities is done away with, and, simultaneously, the mastery of the product over the producer.* Anarchy in social production is replaced by systematic, definite organization. The struggle for individual existence disappears. Then, for the first time, man, in a certain sense, is finally marked off from the rest of the animal kingdom, and emerges from mere animal conditions of existence into really human ones. The whole sphere of the conditions of life which environ man, and which have hitherto ruled man, now comes under the dominion and control of man, who for the first time becomes the real, conscious lord of nature, because he has now become master of his own social organization. The laws of his own social action, hitherto standing face-to-face with man as laws of Nature foreign to, and dominating him, will then be used with full understanding, and so mastered by him. Man's own social organization, hitherto confronting him as a necessity imposed by Nature and history, now becomes the result of his own free action. The extraneous objective forces that have, hitherto, governed history,pass under the control of man himself. Only from that time will man himself, more and more consciously, make his own history — only from that time will the social causes set in movement by him have, in the main and in a constantly growing measure, the results intended by him. It is the ascent of man from the kingdom of necessity to the kingdom of freedom. […] Solution of the contradictions. The proletariat seizes the public power, and by means of this transforms the socialized means of production, slipping from the hands of the bourgeoisie, into public property. By this act, the proletariat frees the means of production from the character of capital they have thus far borne, and gives their socialized character complete freedom to work itself out. *Socialized production upon a predetermined plan becomes henceforth possible.* The development of production makes the existence of different classes of society thenceforth an anachronism. *In proportion as anarchy in social production vanishes, the political authority of the State dies out. Man, at last the master of his own form of social organization, becomes at the same time the lord over Nature, his own master — free.* marxists.org/archive/marx/works/1880/soc-utop/ch03.htm
