The good sense of this able people taught them to distinguish between the different elements in the civilization which they were introducing, to reject those which did not suit them, and to transform others which were better fitted to their inclination. A reaction, however, set in between the eighth and the eleventh centuries which enabled the Japanese to recover sufficient of their identity and yet retain most of the innovations in their industries, agriculture, and fine arts, in the culture of which latter they eventually surpassed their masters. The new religion suited them admirably, and it remains to this day much less corrupt in Japan than it is among the Chinese themselves. The official and administrative system introduced from China, being opposed to the natural bent of the Japanese mind, was, however, soon rejected, and they returned to their own, which suited them better. The mandarinate was never acclimatized, and the principle of heredity always remained in force. The divers degrees of dignity, at first twelve in number and then nineteen, were never given, as in China, to individuals, but to families as hereditary titles. The position, for instance, of Prime Minister, or _Kwambaku_, became hereditary in a great family of the Court, that of the Fujiwaras, from which, moreover, according to tradition, the Empress was invariably selected. Then began to manifest itself that very peculiar trait in the history of Japan of real authority very rarely being vested in the hand of the man supposed to exercise it. The Mikado, who, from the ninth century onwards, was invariably a child, and abdicated in youth to retire into a monastery, is supposed to reign and yet never govern. This was the beginning of a system of Imperial self-effacement which lasted over a thousand years. Presently we discover that the hereditary _Kwambaku_ also exercises no authority, which is exactly the opposite of what took place in Europe in the Middle Ages, where, if a Sovereign retired into privacy, his Prime Minister was pretty certain to become forthwith correspondingly prominent. In the Middle Ages, at an epoch when Europe was engaged in fighting and slaughtering, the Court of Kioto was a centre of art, pleasure and poetry, in which, however, authority was completely set aside.
