This inclusive policy directed against physical exportation, was still more stringently carried out when applied to imports affecting the minds of the Japanese. The "government deliberately attempted to establish a society impervious to foreign ideas from without, and fostered within by all sorts of artificial legislation. This isolation affected every department of private and public life. Methods of education were cast in a definite mould; even matters of dress and household architecture were strictly regulated by the State, and industries were restricted or forced into specified channels, thus retarding economic developments."[3] Starving of the Mind. In the science of keeping life within stunted limits and artificial boundaries, the Japanese genius excels. It has been well said that "the Japanese mind is great in little things and little in great things." To cut the tap-root of a pine-shoot, and, by regulating the allowance of earth and water, to raise a pine-tree which when fifty years old shall be no higher than a silver dollar, has been the proud ambition of many an artist in botany. In like manner, the Tokugawa Shōguns (1604-1868) determined to so limit the supply of mental food, that the mind of Japan should be of those correctly dwarfed proportions of puniness, so admired by lovers of artificiality and unconscious caricature. Philosophy was selected as a chief tool among the engines of oppression, and as the main influence in stunting the intellect. All thought must be orthodox according to the standards of Confucianism, as expounded by Chu Hi. Anything like originality in poetry, learning or philosophy must be hooted down. Art must follow Chinese, Buddhist and Japanese traditions. Any violation of this order would mean ostracism. All learning must be in the Chinese and Japanese languages--the former mis-pronounced and in sound bearing as much resemblance to Pekingise speech as "Pennsylvania Dutch" does to the language of Berlin. Everything like thinking and study must be with a view of sustaining and maintaining the established order of things. The tree of education, instead of being a lofty or wide-spreading cryptomeria, must be the measured nursling of the teacup. If that trio of emblems, so admired by the natives, the bamboo, pine and plum, could produce glossy leaves, ever-green needles and fragrant blooms within a space of four cubic inches, so the law, the literature and the art of Japan must display their normal limit of fresh fragrance, of youthful vigor and of venerable age, enduring for aye, within the vessel of Japanese inclusion so carefully limited by the Yedo authorities.
