The more a social activity, a series of social processes, becomes too powerful for men’s conscious control and grows above their heads, and the more it appears a matter of pure chance, then all the more surely within this chance the laws peculiar to it and inherent in it assert themselves as if by natural necessity. Such laws also govern the chances of commodity production and exchange. To the individuals producing or exchanging, they appear as alien, at first often unrecognized, powers, whose nature must first be laboriously investigated and established. These economic laws of commodity production are modified with the various stages of this form of production; but in general the whole period of civilization is dominated by them. And still to this day the product rules the producer; still to this day the total production of society is regulated, not by a jointly devised plan, but by blind laws which manifest themselves with elemental violence in the final instance in the storms of the periodical trade crises.
