Thus, from the time when the economic type had multiplied sufficiently to hire a police, the strength of the State came to depend on its revenue, and financiers grew to be the controlling element of civilization. Before the crusades, the high offices of the kingdom of France, such as the office of the seneschal, were not only held by nobles, but tended to become hereditary in certain warlike families. After the rise of the Eastern trade the royal council was captured by the bourgeoisie. Jacques Cœur is a striking specimen of the class which ruled in the fifteenth century. Of this class the lawyers were the spokesmen, and men like Flotte and Nogaret, the chancellors of Philip the Fair, expressed the notion of centralization as perfectly as the jurists of ancient Rome. No one has understood the movement better than Luchaire. He has pointed out, in his work on French institutions, that from the beginning of the reign of Saint Louis (1226) the Privy Council steadily gained in consequence.[159] The permanent civil service, of which it was the core, served as a school for judges, clerks, seneschals, and all judicial and executive officers. At first the administration retained a strong clerical tinge, probably because a generation elapsed before laymen could be equally well trained for the work, but after the accession of Philip the Fair, toward the end of the century, the laymen decisively predominated, and when they predominated, the plunder of the Church began. Abstract justice is, of course, impossible. Law is merely the expression of the will of the strongest for the time being, and therefore laws have no fixity, but shift from generation to generation. When the imagination is vivid and police weak, emotional or ecclesiastical law prevails. As competition sharpens, and the movement of society accelerates, religious ritual is supplanted by civil codes for the enforcement of contracts and the protection of the creditor class. The more society consolidates the more legislation is controlled by the wealthy, and at length the representatives of the monied class acquire that absolute power once wielded by the Roman proconsul, and now exercised by the modern magistrate. “The two great figures of Saint Louis and of Philip the Fair which dominate the third period are profoundly unlike, but considering the facts as a whole ... [they] have but moderately influenced the direction of the communal development. With the bailiffs and Parliament the monarchical machine is in possession of its essential works; it operates and will stop no more. In vain the king shall essay to arrest its march, or to direct it in another course: the innumerable army of agents of the crown does not cease for a moment to destroy rival jurisdictions, to suppress embarrassing powers, to replace everywhere private jurisdictions by the single authority of the sovereign.
