When families spread, patriarchal government is said by Pope to have been invariably merged in monarchical. He makes no mention of another elementary system which prevailed among the ancient Germans, and which was too natural to have been unfrequent. The tribe was composed of contiguous families, or clans, each of which had its separate territory. The head of every clan was ruler within his own domain, and the affairs which concerned the entire tribe were managed by a general assembly of the heads of clans. Under this arrangement the representative of the clan preserved his patriarchal power, and had an equal voice with his brother chiefs in regulating the common interests of the tribe. Pope completed his single genealogical principle of government by a rapid summary of the transitions through which monarchy passed. Conquest led to tyranny. An ambitious priesthood first threatened the despot with spiritual terrors, then went shares with him, and the double yoke of secular and ecclesiastical tyranny was fastened on the necks of mankind. The oppressed subjects at last rebelled against their rulers, kings were "forced into virtue by self-defence," and the world returned to the dominant principle of the state of nature, that "self-love and social are the same." These meagre doctrines were derived from Bolingbroke, whose political philosophy was hardly more profound than his moral and metaphysical; but Pope shows, here and there, that he had read Locke's treatise on Civil Government, and the passages from Hooker which Locke quoted, and with such masters to guide him the flimsiness of his views is without excuse. The investigations of Pope conducted him to the final conclusion that "the true end of all government" is unity among mankind, and he prescribes the methods by which harmony is to be preserved both in politics and religion. The panacea which was to cure political divisions is contained in the couplet, For forms of government let fools contest, Whate'er is best administered is best.[880]
