Bolingbroke was typical not only in his attempt to define the true interests of the state but also in his use of the analogy between the political society and the family to assert that not unity but discord was the natural relationship between states. The personal needs of men were met by the development of society out of the family. Self-love, which originally assisted this development and produced separate societies, then ensured that the development would spread no further. "The great commonwealth of mankind cannot be brought under one government, nor subsist without any." As Bolingbroke used these views to make himself an early advocate of a maritime, insular, colonial Great Britain, intervening in European affairs only when her interest in the balance of power required it, so the continental writers of his time completely abandoned the traditional belief in Christendom or Europe as a structure above or at least additional to its component states.
