The independence of the individual has always been tempered by the necessity of belonging to some form of organization. In these days a man belongs to a party, or a trades union or an association, and sacrifices a portion of his independence to the advantages gained by sharing in the strength of an organized coherent body; in ancient times even a modified independence of this kind was not possible, and in early times at Rome a man was expected to vote for his patron through thick and thin. To us it would appear that a man lost personal dignity by following blindly the fortunes of a greater man than himself; to a Roman it would seem that the individual had no personal dignity, if he were not recognizably attached to a patron. Individual independence is only possible in a very highly civilized society. Men may be technically equal in the eyes of the law long before they are so practically; even in modern England it has been found necessary to form associations whose members are bound to mutual assistance in defending or instituting some actions-at-law. The difference between ancient and modern society, and indeed between modern society before and after the French Revolution, lies in this, that the modern association is most commonly one of equal individuals for certain definite purposes, while the ancient association was one of inferiors of various degrees with a superior for all purposes. It would be rash to attempt to define too closely, but the general statement that in ancient Roman society there was no such thing as a free and independent individual, except among the wealthiest or otherwise most powerful, is near the truth. Numberless conditions unknown to modern society contributed to produce the same result; among them the following may be mentioned. Residence as a means of acquiring political status was not recognized by the ancients; a man might reside in the same town all his life, and his children might succeed him, but neither he nor they could buy or sell, plead in the law courts, intermarry with the citizens, acquire real property, or in fact enjoy any of the benefits of civilized society, without making special arrangements; the resident was an alien until the authorities of the town in which he dwelt had conferred upon him a political status. Towns such as Rome and Athens, which admitted resident aliens comparatively readily to a modified form of citizenship, expanded more quickly than other towns, and the history of the expansion of Rome is from this point of view the history of the processes by which she gradually admitted the stranger within her gates, and then the stranger without her walls to the privileges of citizenship.
