At the same time, in the eighteenth century a whole college of literary men and a distinct school of literature rose, whose principal object was the study of the ancient texts, to collate, publish, and interpret them, whereby certain political and religious conclusions were arrived at, tending to prove that the only legitimate power in Japan was the autocracy of the Mikado, the descendant of the gods, and the only true religion Shintoism, and that patriotism, moreover, demanded the restoration of the ancient political and social organization which had existed in the Empire long before the introduction of Buddhism, feudalism, and of Chinese ideas in general. If these theories did not interest the people, they certainly, and very effectively, created a breach between the literary classes and the _samourai_, on the one hand, and the Shogunate and its supporters, who by this time had become not only unpopular with the productive classes of the nation, but were even looked upon in the light of a tax, against which the people very naturally rebelled, failing to see why they should be called upon to support an idle and otherwise useless caste. In 1700 the Government, financially embarrassed, was compelled to diminish the number of charges imposed upon it by the feudal system, and to increase taxation, whereupon the merchants deemed it prudent to conceal the exact amount of their fortunes, and the peasants, who paid their lords a third or a half of their harvests, were not infrequently ransomed by the _ronin_. Under these circumstances the feudal system could no longer endure, since it was now brought into contact with a society richer and better organized than itself, and thus it became impossible for the Japanese Government to prevent the penetration into the Empire of European ideas, which filtered through the one port, Nagasaki, left partially open for the benefit of the Dutch. From the eighteenth century onwards certain young _samourai_ were always to be found at this port endeavouring to place themselves in contact with the Dutch. The Shogun Tzunayoshi (1650–1709) pretended not to notice what was happening, although his Government was ostentatiously endeavouring to repress any kind of intercommunication between the natives and foreigners.
