How rapidly after the establishment of individual exchange and after the transformation of products into commodities the product manifests its rule over the producer, the Athenians were soon to learn. Along with the production of marketable commodities came the tilling of the soil by individual cultivators for their own account, soon followed by individual ownership of the land. Along came also the money, that general commodity for which all others could be exchanged. But when men invented money they little suspected that they were creating a new social power, that one universal power before which the whole of society must bow down. It was this new power, suddenly sprung into existence without the forethought and intention of its own creators, that vented its rule on the Athenians with the full brutality of youth. What was to be done? The old gentile organization had not only proved impotent against the triumphant march of money: it was also absolutely incapable of containing within its confines any such thing as money, creditors, debtors and forcible collection of debts. But the new social power was upon them and neither pious wishes nor a longing for the return of the good old times could drive money and usury from the face of the earth. Moreover, gentile constitution had suffered a number of minor defeats. The indiscriminate mingling of the gentiles and phrators in the whole of Attica, and especially in Athens, had assumed larger proportions from generation to generation. Still even now a citizen of Athens was not allowed to sell his residence outside of his gens, although he could do so with plots of land. The division of labor between the different branches of production--agriculture, trades, numberless specialties within the trades, commerce, navigation, etc.--had developed more fully with the progress of industry and traffic. The population was now divided according to occupations into rather well defined groups, everyone of which had separate interests not guarded by the gens or phratry and therefore necessitating the creation of new offices. The number of slaves had increased considerably and must have surpassed by far that of the free Athenians even at this early stage. Gentile society originally knew no slavery and was, therefore, ignorant of any means to hold this mass of bondsmen in check. And finally, commerce had attracted a great many strangers who settled in Athens for the sake of the easier living it afforded. According to the old constitution, the strangers had neither civil rights nor the protection of the law. Though tacitly admitted by tradition, they remained a disturbing and foreign element.
