Another of Sun's programs relates to the question: How can democracy be reconciled with ideological control? The Chinese had lived in a society so completely under the rule of common ideas that independent individual thinking had to be moderate, careful, and orthodox in appearance before it met with any welcome. The individual was not free to think freely; but since most did not think freely, sensing no need for it, they were unconscious of control. A problem larger than that of individual freedom is raised by the question of ideological control, since the controlled individual himself transmits control to his neighbors and his dependents. The ideology must be filtered, as it were, at some point. Sun believed that democracy would effectuate the filtering, allowing long-range revision from outside the bureaucracy. He expected that the bureaucracy of democratic China would rule well but would be subject to control from a people not completely under its thumb. The ideology was to be officially fostered, but it was to be subject to the check of the electorate. The Chinese were still to use orthodoxy as a tool of control and social pressure as the major instrument of constraint, but they were not to be allowed to fall into a blind traditionalism which would isolate them. The old ideology was to be adjusted and supplemented with Western science, so that the new would be compounded of three things: old Chinese social and political experience, old Chinese ethical knowledge, and modern scientific truth. With respect to Western science, the Nationalists had to present few startling governmental innovations, since the need for a knowledge of the physical and technical sciences was widely recognized in China--not only by the Nationalists. That the Western technology should serve to build the new China was obvious; trade schools needed encouragement rather than initiation. As to the old Chinese social and political experience, the Kuomintang stressed study of China's past. They attempted to mend the gap between the generation born in the 1880's and that born in the 1910's by encouraging concentration on the classical texts, reverently, but critically as well. Archaeology has heightened interest of the Chinese in their past. As a consequence, their sense of national value has deepened.
