During this process of universal assimilation and annexation, the almost supernaturally active First August Emperor made tour after tour throughout his new dominions, showing a special predilection for the coasts, for Tartarland, and for the Lower Yang-tsz River; but not venturing far up or far south of that Great River; and even when he did so venture a short distance, never leaving the old and well-known water routes: nor did he risk a land journey to Sz Ch'wan, to which country there were at the time no roads of any kind at all possible for armies. It is well known that both he and the legal, international, political, and diplomatical adventurers who had been for a century or more from time to time at his court had been strongly imbued with the somewhat revolutionary and then fashionable democratic principles of the new Taoism, as defined by the philosopher Lao-tsz; but he showed no particular hostility to orthodox literature until, whilst on his travels, deputations of learned men, especially in the ritual centres of Lu and Ts'i, began to suggest to him the re-establishment of the old feudal system, and to "quote the ancient scriptures" to him by way of protesting mildly against his too drastic political changes. It has been explained in Chapter XIII. that in 626 B.C., when his great ancestor Duke Muh had availed himself of the advisory services of an educated Tartar (of Tsin descent), this Tartar had made use of the expression: "The King of the Tartars governs in a simple, ready way, without the aid of the Odes and the Book as in the case of China." Thus it was that, possibly with this ancient warning in his mind, he conceived a sudden, violent, and passionate hatred for didactic works generally, and two books in particular-the very two, passages from which pedants, philosophers, ambassadors, and ministers had for centuries hurled at each other's heads alike in convivial, argumentative, and solemn moments. In other words, the Odes and the Book, together with Confucius' "Springs and Autumns," with its censorious hints for rulers, and all the other local Annals and Histories, were under anathema, But more detestable even than these were the new philosophical treatises of a polemical kind, which girded at monarchs through their subtle choice of words and anecdotes, or which recalled the good old times of the feudal emperors and their not very obsequious vassals. His self-laudatory inscriptions upon stone, scattered about as he travelled from place to place, tell us plainly, in his own royal words, that this hatred of presumptuous vassal claims was his prime motive in destroying all the pedants and books he could secure. He denounces the vassals of bygone times who ignored the Supreme Emperor, fought with each other, and had the insolence to "carve stone and metal in order to record their own deeds." The Changes are quoted in history often enough by statesmen, as well as the Odes and the Book;
