at the beginning of the _History_ of Thucydides, and Polybius will be found discoursing of the progress that had been made in all the arts, while Cicero, Quintilian, and several others trace the progress of rights and of literature. There are also touches of human value in conflict with one another in the narratives of the struggles between Greeks and barbarians, between the truly civil and active life of the former and the proud, lazy habits of the latter. Other similar conceptions of human values will be found in many comparisons of peoples, and above all in the way that Tacitus describes the Germans as a new moral power rising up against that of ancient Rome, and perhaps also in the repugnance which the same historian experiences at seeing before him the Jews, who follow rites _contrarius ceteris mortalibus._ Finally, Rome, mistress of the world, will sometimes assume in our eyes the aspect of a transparent symbol of the human ideal, analogous to Roman law, gradually idealized in the form of natural law. But here it is rather a question of symbols than of conceptions, of our own conclusions than of the thoughts proper to the ancients. When, for instance, we examine the history of philosophy of Aristotle as outlined by him, we find that it consists above all in a rapid critical account to serve as propædeutic to his system; and literary and artistic histories and histories of civilization seem often to be weakened by the prejudice that these are not really necessary mental forms, but luxuries and refinements. At the utmost we can speak of exceptions, incidents, tentatives; which does not in any way alter the comprehensive impression and general conclusion to the effect that the ancients never possessed explicit histories of civilization, philosophy, religions, literature, art, or rights: none, in fact, of the many possessed by ourselves. Nor did they possess 'biography' in the sense that we do, as the history of the ideal function of an individual in his own time and in the life of humanity, nor the sense of development, and when they speak of primitive times they rarely feel that they are primitive, but are rather disposed to transfigure them poetically, in the same way that Dante did by the mouth of Cacciaguida that Fiorenza which "stood soberly and modestly at peace" within the circle of the ancient days. It was one of the "severe labours" of our Vico to recover the crude reality of history beneath these poetic idylls. In this work he was assisted, not by the ancient historiographers, but by documents and mostly by languages.
