There were branches of classical philology in which the Renaissance was backward. The general purpose was to set up Plato in the place of Aristotle, discredited as as accomplice of the obscurest schoolmen. Under the Medici, a Platonic academy flourished at Florence, with Ficino and Politian at its head. But there was a tendency to merge Plato in Neoplatonism, and to bridge over what separated him from Christianity. Neither the knowledge of Plato, nor the knowledge of the Gospel, profited by the endeavour. The only branch of literature in which the Renaissance gave birth to real classics, equal to the ancients, was politics. The medieval theory of politics restrained the State in the interest of the moral law of the Church, and of the individual. Laws are made for the public good, and, for the public good, they may be suspended. The public good is not to be considered, if it is purchased at the expense of an individual. Authorities are legitimate if they govern well. Whether they do govern well those whom they govern must decide. The unwritten laws reigns supreme over the municipal law. Modern sentiments such as these could not be sustained in the presence of indifference to religion, uncertainty as to another world, impatience of the past, and familiarity with Hellenistic thought. As the Church declined the ancient State appeared, a State which knew no Church, and was the greatest force on earth, bound by no code, a law to itself. As there is no such thing as right, politics are an affair of might, a mere struggle for power. Such was the doctrine which Venice practised, in the interest of a glorious and beneficent government, and which two illustrious writers, Machiavelli and Guicciardini, made the law of modern societies.
