Looking back over the space of a thousand years, which we call the Middle Ages, to get an estimate of the work they had done, if not towards perfection in their institutions, at least towards attaining the knowledge of political truth, this is what we find: Representative government, which was unknown to the ancients, was almost universal. The methods of election were crude; but the principle that no tax was lawful that was not granted by the class that paid it--that is, that taxation was inseparable from representation--was recognised, not as the privilege of certain countries, but as the right of all. Not a prince in the world, said Philip de Commines, can levy a penny without the consent of the people. Slavery was almost everywhere extinct; and absolute power was deemed more intolerable and more criminal than slavery. The right of insurrection was not only admitted but defined, as a duty sanctioned by religion. Even the principles of the Habeas Corpus Act, and the method of the Income Tax, were already known. The issue of ancient politics was an absolute state planted on slavery. The political produce of the Middle Ages was a system of states in which authority was restricted by the representation of powerful classes, by privileged associations, and by the acknowledgment of duties superior to those which are imposed by man. As regards the realisation in practice of what was seen to be good, there was almost everything to do. But the great problems of principle had been solved, and we come to the question, How did the sixteenth century husband the treasure which the Middle Ages had stored up? The most visible sign of the times was the decline of the religious influence that had reigned so long. Sixty years passed after the invention of printing, and thirty thousand books had issued from European presses, before anybody undertook to print the Greek Testament. In the days when every State made the unity of faith its first care, it came to be thought that the rights of men, and the duties of neighbours and of rulers towards them, varied according to their religion; and society did not acknowledge the same obligations to a Turk or a Jew, a pagan or a heretic, or a devil worshipper, as to an orthodox Christian. As the ascendency of religion grew weaker, this privilege of treating its enemies on exceptional principles was claimed by the State for its own benefit; and the idea that the ends of government justify the means employed was worked into system by Machiavelli. He was an acute politician, sincerely anxious that the obstacles to the intelligent government of Italy should be swept away. It appeared to him that the most vexatious obstacle to intellect is conscience, and that the vigorous use of statecraft necessary for the success of difficult schemes would never be made if governments allowed themselves to be hampered by the precepts of the copy-book.
